1 Summary
1.1 General(Figures 2/1 to 2/8)
The vacuum circuit-breakers of type VD4 areintended for indoor installation in air-insulatedswitchgear systems. They have a switchingcapacity capable of handling the loads occuringat start-up and shutdown of equipment and plantunits both in normal and in fault state.
Vacuum circuit-breakers have particular advan-tages for use in networks where there is a highswitching frequency in the working current rangeand/or where a certain number of short-circuitbreaking operations are expected. Type VD4vacuum circuit-breakers are suitable for autore-closing, and have exceptionally high operatingreliability and long life.
The vacuum circuit-breakers of type VD4,designed in column form, can be supplied bothas individual units for fixed installation andmounted on chassis. Their basic structure isshown in figures 2/1 to 2/8.

4 Structure and function
4.1 Basic structure of the circuit-breaker onwithdrawable breaker assembly(Figures 4/1 to 4/3 and 7/1)
The withdrawable part, which can be movedmanually or by a motor if fitted, consists of a steelsheet structure on which the circuit-breaker with itsancillary components is mounted.
Insulated contact arms 6 with the spring-loadedcontact systems 7 are fitted to the circuit-breakerpoles. These create the electrical connection to thepanel when the withdrawable part is inserted intothe service position.
A multi-pole control wiring plug connector 8connects the signalling, protection and controlwiring between the panel and the withdrawablepart.
The withdrawable assembly and the circuit-breakerare connected via a multi-pole control wiring plugconnector 8.3.
As soon as the withdrawable part has been slidinto the panel and its base frame has engaged inthe test/disconnected position, it is positively con-nected to the panel. At the same time, it is earthedby its travel rollers in their rails. The stored-energyspring mechanism of the circuit-breaker, includingits controls and indicators, is accessible at the frontof the withdrawable part.
Withdrawable parts of the same version areinterchangable. With the same dimensions but dif-ferent circuit-breaker equipment, coding of thecontrol wiring plug prevents impermissiblecombinations of withdrawable parts and panels.
4.2 Structure of the breaker poles(Figures 4/2, 4/5 and 4/6)
The poles in column design are mounted on thebracket-shaped rear part of mechanism enclosure 9.1.The live parts of the breaker poles are enclosed incast resin and protected from impacts and otherexternal influences.
With the breaker closed, the current path leadsfrom the upper breaker terminal 21 to the fixedcontact 20.2 in the vacuum interrupter 20, then viathe moving contact 20.3 and flexible connector 23(or via multi-contact strips, depending on ratedcurrent) to the lower breaker terminal 22.
The switching motions are effected by means ofthe insulated link rod 26 with internal contact forcesprings 25.
4.3 Structure of the breaker operating mechanism(Figures 4/4, 4/6 and 4/7)
The operating mechanism is of the stored-energyspring type. The necessary operating energy isstored ready for activation by charging the springenergy storage mechanism.
The stored-energy spring mechanism essentiallyconsists of drum 33 containing the spiral spring,the charging system, the latching and operatingmechanism and the linkages which transmit theforce to the breaker poles. In addition, there aresupplementary components such as the chargingmotor, releases, auxiliary switches and the controlsand instruments located on the front of themechanism enclosure 9.1.
The operating mechanism is fundamentally suitablefor auto-reclosing and, due to the short chargingtimes, also for multi-shot auto-reclosing.
In the basic version of the circuit-breaker, thespring energy storage mechanism is chargedmanually. The operating mechanism can optionallybe fitted with a charging motor.
There is one rating plate with the main data of theswitch equipment on front plate 9.2, and another atthe lower front right in mechanism enclosure 9.1.
The basic version of the stored-energy springmechanism is fitted with the following auxiliaryequipment:
• Shunt release OFF -Y2
• Five-pole auxiliary switch -S4 forannunciation purposes
• Auxiliary switch -S7 for fault annunciation
• Mechanical ON push-button 11
• Mechanical OFF push-button 12
• Mechanical position indicator 13
• Charging condition indicator 18 for thespring energy storage mechanism
• Mechanical operating cycle counter 14.
The following additional equipment can be installed:
• Blocking magnet -Y1 with auxiliary switch -S2
• Shunt release ON -Y3
• Second shunt release OFF -Y9
• Indirect overcurrent release -Y7
• Undervoltage release -Y4
• Five-pole auxiliary switches -S3 and -S5
• Charging motor -M0
• Five-pole auxiliary switch -S1 to switch thecharging motor.
4.3.1 Releases, blocking magnet and auxiliary switches(Figures 2/15, 4/4, 4/7 and 8/1 to 8/3)
• The releases and the blocking magnet aremounted at the top left on the spring operatingmechanism.
• The allocation of the auxiliary switches can beseen in the wiring diagram of figure 2/15.
33
• The five-pole auxiliary switch -S1 is operated bythe charging condition indicator 18. It controls thecharging motor -M0, serves as an electrical inter-lock for shunt release ON -Y3 when the springmechanism is not sufficiently charged, and alsoprovides an electrical switching readiness signal.
• Operation of the five-pole auxiliary switches-S3, -S4 and -S5 is dependent on the switchingposition of the circuit-breaker.
• Auxiliary switch -S3 interrupts the circuit of theoptional additional shunt release OFF -Y9 withthe circuit-breaker in the open position, and thecircuits of shunt release ON -Y3 and the optionalblocking magnet -Y1 with the circuit-breaker inthe closed position. There is one further NOC forother purposes.
• On failure or absence of the control voltage,blocking magnet -Y1 mechanically locks the ONhalf shaft and simultaneously acts on the corre-sponding auxiliary switch -S2 to interrupt thecircuit of shunt release ON -Y3.
• Blocking magnet -Y1 is accessible when frontplate 9.2 is removed.
• Auxiliary switch -S4 interrupts the circuit of shuntrelease OFF -Y2 with the circuit-breaker inthe open position. One further NOC and threeNCCs are available for annunciation, control andinterlock purposes.
• Auxiliary switch -S5 can be optionally designedwith any possible combination of contacts fromfive NOCs to five NCCs. Its contacts are availa-ble for any required control, annunciation or in-terlock functions. The auxiliary switch is normallyconfigured as shown in figure 2/15.
• The single pole auxiliary switch -S7 (fleeting con-tact time ≥ 30 ms) serves to provide a fault signal("breaker released").With remote control, the auxiliary switch isnecessarily operated by:
– Shunt release OFF -Y2 or
– Shunt release OFF -Y9 or
– Undervoltage release -Y4 or
– Indirect overcurrent release -Y7.
Note:
1. Shunt releases OFF (-Y2) and ON (-Y3) are ex-clusively provided for opening and closing in nor-mal operation. For safety breaking operations,the second shunt release OFF (-Y9) must beused, in most cases with a separate controlvoltage supply.
These three releases are of the solenoid typeand suitable for a large number of operatingcycles.
2. The undervoltage release (-Y4) and/or indirectovercurrent release (-Y7) are pure safety andprotection releases and must not be used forswitching in normal operation.
4.3.2 Mounting of the VD4 on trucks from othermanufacturers
VD4 circuit-breakers which are not installed onABB withdrawable parts must be fitted with oneor two additional auxiliary switches which aredependent on the mechanical lock and releasedevice. These must interrupt the circuit of shuntrelease ON -Y3.
Similary to auxiliary switches -S8 and -S9 in CalorEmag withdrawable parts, no electrial pulse mayarrive during and before mechanical blocking of thespindle mechanism, and may only be applied againafter the end of mechanical blocking.This ensures that the shunt release ON cannot beloaded with an electrical ON pulse when thewithdrawable part is in an intermediate position,which could burn out the coil.
4.4 Function
4.4.1 Charging of the spring energy storage mechanism
(Figures 4/6, 4/7 and 7/1)
To provide the necessary motive energy, the springenergy storage mechanism, either charged auto-matically by a charging motor or manually in avertical pumping action with charging lever 19,depending on the equipment fitted to the circuit-breaker. The current charging condition is shown atcharging condition indicator 18.
As a precondition for an auto-reclosing sequence,the operating mechanism is either (re-)charged aftera closing operation automatically by the chargingmotor, or it requires (re-)charging by hand if theoperating mechanism is of the manual type.
4.4.2 Closing procedure
(Figures 4/4, 4/6 and 4/7)
The closing process is started by the mechanicalON push-button 11, or by activation of shunt releaseON -Y3. The release mechanism 31 then permitsdrive shaft 30 to be rotated by the (previously)charged spiral spring. The moving contact 20.3 invacuum interrupter 20 is moved until the contactstouch by cam disk 29 and further kinematic links. Inthe further sequence of motion, spring arrangement25 is tensioned and the appropriate amount ofcontact force thus applied. The available overtravelis higher than the maximum value of contact erosionduring lifetime of the interrupter. During the closingprocess, opening springs 27 are simultaneouslytensioned.
34
4.4.3 Opening procedure
(Figures 4/4, 4/6 and 4/7)
The opening procedure is initiated by mechanical OFFpush-button 12 or by activation of one of releases -Y2,-Y4, -Y7 or -Y9. Observe the notes in section 4.3.1 oncontrol of the releases. Release mechanism 31 thenpermits drive shaft 30 to be turned further by the springenergy storage mechanism, which is still sufficientlycharged. Opening spring 27, which is thus released,moves contact 20.3 into the open position at a definedspeed.
4.4.4 Auto-reclosing sequence
An OFF-ON or OFF-ON-OFF auto-reclosing sequen-ce is activated and checked by the protectionsystem. It is necessary for the spiral spring in theoperating mechanism to be in the (re-)chargedcondition, with the circuit-breaker in the closedposition. The (re-)charging process is carried outautomatically after closing of the breaker onbreakers with motor charging mechanisms, butmust be carried out manually on breakers withoutcharging motors (or when the charging motor hasbroken down). Opening of the breaker is alsopossible during the (re-)charging process, but sub-sequent closing of the breaker is however blockeduntil the charging process has been completed.
4.4.5 Quenching principle of the vacuum interrupter
Due to the extremely low static interrupter cham-ber pressure of 10-4 to 10-8 mbar, only a relativelysmall contact gap is required to achieve a highdielectric strength. The arc is extinguished on oneof the first natural current zeros.
Due to the small contact gap and the highconductivity of the metal vapour plasma, the arcdrop voltage, and additionally, due to the shortarcing time, the associated arc energy, are extre-mely low, which has advantageous effects onthe life of the contacts and thus on that of thevacuum interrupters.
4.5 Interlocks/protection against maloperationfor the withdrawable circuit-breaker part
A series of interlocks are provided to preventdangerous situations and any maloperation. Theinterlocks of the panel system ZS and/or themounting frame, which are normally effective, areas follows (concerning the circuit-breaker):
• The withdrawable part can only be moved fromthe test/disconnected position into the serviceposition (and back) with the circuit-breaker openand the earthing switch open (that means thatthe breaker must opened before)
• The circuit-breaker can only be closed when thewithdrawable part is precisely in the defined testposition or service position (mechanical inter-lock, with additional electrical interlock forcircuit-breakers with electrical releases).
• The circuit-breaker can only be openedmanually in the service or test position when nocontrol voltage is applied, and cannot be closed(electromechanical interlock).
• Connection and disconnection of the controlwiring plug connector (8.1) is only in the test/disconnected position possible.
• The earthing switch can only be closed when thewithdrawable part is in the test/disconnectedposition or the removed position (mechanicalinterlock).
• The withdrawable part cannot be moved fromthe test/disconnected position into the serviceposition when the earthing switch is closed(mechanical interlock).
• Details of any additional interlocks, e.g. inconnection with a blocking magnet on thewithdrawable part and/or earthing switchoperating mechanism, can be found in the orderdocuments for each individual case (see alsosection 8.5.6).

• This switchgear may only be operated byspecially trained personnel who are familiar withthe characteristics of the particular device.
• Observe the relevant instructions in section„Standards and specifications“.
7.2 Preparatory activities(Prior to application of primary voltage)• Check the circuit-breaker for any kind of damage
or other injurious environmental influence, andrestore to the proper condition where necessary.
• Remove any contamination, particularly oninsulating parts, which has occurred duringtransit, storage or installation.
• Lifting lugs for high current circuit-breakers, if stillfitted, must be removed.
• Check the primary and secondary connectionsand the protectiv conductor terminal.
• Check mechanical and electrical interlocks foreffectiveness, without using force.
• Charge the spring energy storage mechanismby hand (see section „Charging the springenergy storage mechanism“).
• For test purposes, switch the mechanism on andoff using the mechanical operating elements 11 or12 (note in this context any specified designsupply voltage and any interlocks installed).
• Check the charging motor on circuit-breakerswith motor-operated mechanisms by applyingsupply voltage.
• On motor-driven withdrawable parts, check thedirection of rotation of the travel motors asdescribed in section „Checking the direction ofrotation of the travel motors ...“.
• For any further questions on the functions of thewithdrawable circuit-breaker part and its testing,see section „Testing withdrawable parts“.
• Ensure that the Instruction Manual is available tothe operators at all times.
7.3 Movement of the withdrawable breaker part(Figures 4/1, 4/2, 4/3, 7/1 to 7/4)Perform switching operations with the front doors shut.
7.3.1 Manual insertion from the test/disconnectedposition to the service position
• Connect control wiring plug 8.1.• Close the front door.• Ensure that the circuit-breaker is in the OFF
position.• Fit hand crank 5 on square spigot 4.2 of the
spindle mechanism 4.
6 Installation and mounting of thebreakerCareful and professional installation of the switch-gear is one of the fundamental conditions oftrouble-free circuit-breaker operation.
• Install the mechanism enclosure in the panelwithout tension or distortion, inserting dishedwashers below the nuts or bolt heads at each ofthe four mounting points (dependent on theorder).
• Connect the main terminals without any perma-nent tension or pressure forces, exerted forexample by the conductor bars.
• When connecting the conductor bars, the boltsmust be inserted to the depth shown on thedimensional drawing.
• Take account of any tested terminal zone.
• Use DIN bolts of tensile class 8.8, fasteningconductor bars together with dished washers.
• Make a short-circuit proof connection betweenthe PE conductor and the main earthing bar inthe switchgear, using contact washers.
• Remove any dirt. See also section „Servicing“.

It is recommended that the threads or head contact surfacesof the bolts be lightly oiled or greased, so as to achieve aprecisely defined rated tightening torque.
39
Note:In order to avoid damage to the operatingmechanism, use the original hand crank only:
– Standard version without slip clutch– Optional version with slip clutch.
• Turn the crank clockwise according the tableuntil the stop is reached and the withdrawablepart is in the service position.
Note:
Do not force to move the withdrawablebreaker part (max. torque 25 Nm)!
Comply with the conditions for movement of thewithdrawable part as set out in section 8.5.6!

• Observe the position indicator.
• Remove hand crank 5 by pressing first againstthe hand crank and then remove.
Note:
When removing the crank, it is essential to ensurethat the spring-loaded scene head 4.1 slides intothe untensioned front position. Spindle 4 is thuslocked in place, preventing inadvertent turning ofthe spindle. Turning of the spindle opens auxiliaryswitches -S8/-S9 and thus prevents the circuit-breaker from being operated.
Note:
The withdrawable part must not be stopped at anyposition in the travel range between the serviceposition and test/disconnected position!
7.3.2 Manual withdrawal from the service position intothe test/disconnected position
• Ensure that the circuit-breaker is in the OFFposition.
• Reverse the procedure described above forinsertion into the service position.
Note:
Withdrawable parts with blocking magnet -Y0 maynot be forcibly moved during power failures. Insuch a case they are blocked in the service and testpositions. For deblocking, see section 8.5.6.
7.3.3 Motor-driven movement of the withdrawable part
• Briefly operate the electrical control for insertionor withdrawal (the withdrawable part thenautomatically moves into the opposite position).
• Observe the position indicator.Note:
When the motor fails, the withdrawable part can bemoved in emergency manual operation. If the drivemotor fails during movement of the withdrawablepart, the withdrawable part must be moved into alimit position in emergency manual operation.
As a precondition for an auto-reclosing sequence,the operating mechanism is either (re-)chargedafter a closing operation automatically by thecharging motor, or it requires (re-)charging byhand if the operating mechanism is of the manualtype.
Emergency manual operation:
Emergency manual operation is carried out with thehand crank 5 on the spindle mechanism 4, in asimilar manner to operation of a withdrawablebreaker part with manual systems:
• Turn off the supply voltage (m.c.b.), since themotor would otherwise be braked electrically.
• Turn hand crank 5 in the required direction.
When the withdrawable part moves, the motorturns. The motor functions in such a case like agenerator, i.e. it can lead to reverse voltages inthe terminals.
The motor protection device must not bechanged from the specified type and ratedvalue, or the behaviour of the permanent magnetmotor could be irreversibly impaired
7.3.4 Withdrawal from the test/disconnected positiononto the service truck
• Open the door of the circuit-breaker compartment.• Release control wiring plug 8.1 and engage it in
the storage position on the withdrawable part.
• Position service truck 48 with the guide pins48.2 of the adjustable bench top at the correctheight facing the panel front, and allow catch48.3 to engage.
• Move sliding handles 3.1 inwards against thesprings to release withdrawable part 1, withdrawonto the service truck and secure it in thecatches on the truck.
• Press the release lever (at the front underneaththe bench top) and release the service truckfrom the panel.
40
7.3.5 Insertion from the service truck into the test/disconnected position
• Carry out the procedure as described above forwithdrawal, changing the order accordingly.
7.4 Operation of the circuit-breaker
(Figures 4/4 and 7/1)
7.4.1 Charging the spring energy storage mechanism
Circuit-breakers with charging motors:• Charging takes place automatically.• If the charging motor breaks down, the charging
process can be carried out or completed manually.
Circuit-breakers with manual charging mecha-nisms:• Insert charging lever 19 into recess 15 and
pump up and down for approx. 25 strokesuntil the charged condition is displayed.
• When the charged condition is reached, thecharging mechanism automatically disengages,and further strokes of the charging lever have noeffect.
Key to the charging condition indications:
Discharged Charged
As a precondition for an autoreclosing sequence,the operating mechanism is either (re-)chargedafter a closing operation automatically by thecharging motor, or it requires (re-)charging byhand if the operating mechanism is of the manualtype.
7.4.2 Closing and opening the circuit-breaker
With the withdrawable part in the service position,on and off switching operations should only becarried out with the doors closed.
• Closing operation:
Press mechanical ON push-button 11, oroperate the electrical control unit.
• Opening operation:
Press mechanical OFF push-button 12, oroperate the electrical control unit.
Observe the notes in section 4.3.1.
The operating cycle counter 14 is automaticallyincremented by one complete figure with eachswitching cycle. On completion of a switchingoperation the position indicator 13 in the windowof front plate 9.2 shows the appropriate positionof the circuit-breaker.
• Anti-pumping relay:
The anti-pumping relay-K0 (wiring diagram infigure 2/15) prevents repeated ON-OFF swit-ching operations if, for example, the breaker istripped by a protection relay in response to aprimary side fault while a permanent electricalclosing command is simultaneously applied. Thecircuit-breaker can then only be closed after theclosing command has been interrupted.
• Closing on failure of supply voltage:
– With standard equipment:
On failure of the control voltage, mechanicalclosing by means of ON push-button 11 ispossible at any time.
– With blocking magnet -Y1 fitted:
On failure of the control voltage, blockingmagnet -Y1 mechanically locks the ONhaflshaft and simultaneously interrupts thecircuit shunt release ON -Y3 via the cor-responding auxiliary switch -S2.
Closing with the blocking magnet de-energised requires manipulation of the circuit-breaker operating mechanism:
– Remove front plate 9.2.
– Take care to avoid rotating parts!
• Opening on failure of supply voltage:
On failure of the supply voltage, mechanicalopening by means of OFF push-button 12 ispossible at any time.

8 Maintenance
Maintenance serves to ensure trouble-freeoperation and achieve the longest possible work-ing life of the switchgear. In accordance withDIN 31 051 / IEC 61208 it comprises the followingclosely related activities:
Inspection:Determination of the actual conditionServicing: Preservation of a functional condition
Repair: Measures to restore the functionalcondition
8.1 General
Vacuum circuit-breakers are characterized bytheir simple and robust construction. They have along life expectancy. Their operating mechanismshave a low maintenance requirement, and theinterrupters are maintenance-free during theirworking life. There is no adverse effect on thevacuum, even from frequent switching of operatingand short-circuit currents.
The servicing intervals and scope are determined byenvironmental influences, the switching sequencesand number of short-circuit breaking operations.
Note:
The following must be observed for all maintenancework:
• The relevant specifications in section “Standardsand specifications“
• Notes on safety at work in section “Commis-sioning/Operation“
• Standards and specifications in the country ofinstallation.
Maintenance work may only be performed by fullytrained personnel, observing all the relevant safetyregulations. It is recommended that ABB after-sales service personnel should be called in, at leastduring the performance of servicing and repairwork.
While the work is in progress, all supply voltagesources must also be disconnected and securedto prevent reconnection.
Note:
In order to prevent accidents (particularly injury tohands!) extreme care should be taken duringall repair work on the operating mechanism,especially with front plate removed.
The spiral spring in the spring energy storagemechanism, for instance, retains a basic tensionwhich is independent of the charging anddischarging processes during switching, so as toensure correct function. This spring energy canbe inadvertently released if work is performedincorrectly on the spring mechanism!
8.1.1 Service-life
Typical life-expectancies for VD4 circuit-breakers:
• Vacuum interrupter chambers: Up to 30,000switching cycles, depending on chamber type(see section “Permissible numbers of switchingcycles“)
• Device: Up to 30,000 cycles under normaloperating conditions, depending on breakertype, and given regularly and conscientiouslyperformed maintenance
• Withdrawable assembly: With careful operationand appropriately performed inspection work,up to 1000 movement operations can beachieved.See also IEC 60298
The service life data fundamentally apply to allcomponents which are not directly influenced bythe operator.
Components operated manually (movement of thewithdrawable part, etc.) may deviate.
8.2 Inspection and functional testing
8.2.1 Switching devices in general
• The proper condition of the switching device isto be verified by regular inspection.
• The checks are to be performed in accordancewith BGV A3 standard.
• Inspection at fixed intervals may be waived if theswitchgear is permanently monitored by aqualified personnel.
• The checks first and foremost comprise visualexamination for contamination, corrosion,moisture and discharge phenomena.
• In unusual operating conditions (includingadverse climatic conditions) and/or special envi-ronmental pollutions (e.g. heavy contaminationand aggressive atmosphere), inspection mayalso be necessary at shorter intervals.
• Visual checking of the isolating contact system.We recommend to turn alternately the contactsystem in order to clean the inner contact pointsof the contact system.
The contact points should be cleaned if signs ofunperminable overheating (discoloured surface)are visible (see section “Repair“)
• If an incorrect condition is found, appropriateservicing measures are to be initiated.
8.2.2 Stored-energy spring mechanism
Functional testing of the operating mechanism is tobe performed:
• after 5000 operating cycles or
• during servicing work as set out in section„Inspection, switching devices in general“.
43
necessary in accordance with the safetyregulations of DIN VDE/IEC.
• Cleaning of surfaces in general:
– Dry, lightly adhering dust deposits with a soft,dry cloth.
– More strongly adhering contamination withslightly alkaline household cleanser or RivoltaBWR 210.
• Cleaning of the insulating material surfaces andconductive components:
– Light contamination:with Rivolta BWR 210.
– Strongly adhering contamination:with cold cleanser 716.
Wipe down after cleaning, using clean water,and dry properly.
• Observe the manufacturer’s instructions and thespecial ABB Instruction Manuals BA 1002/E orBA 1006/E on safety at work.
Note:
Use only halogen free cleansers, and in no case1.1.1-trichloroethane, trichloroethylene or carbontetrachloride!
8.3.2 Stored-energy spring mechanism
Servicing of the operating mechanism is to beperformed after 10,000 operating cycles.
Prior to servicing, switch the breaker off, and
• move it out of the panel (with withdrawablebreakers) or
• isolate the outgoing feeder (with stationarymounted breakers).
Observe the safety regulations.
Details of the servicing:
• Switch off the charging motor (if fitted), anddischarge the spring energy storage mechanismby closing and opening the breaker once.
• Replace parts subject to high climatic andmechanical stresses as a precaution.
• For replacing highly stressed parts neutralizebasic tension of the spiral spring, state the rate.Be careful when carrying out!
• Relubricate pawls, support shafts, sliding androtating bearing surfaces. Lubricant:
Isoflex Topas NB 52.
• Check the fit of fasteners (e.g. locking pins) incranks, pins, bolts etc. Check the tightnessof fastening bolts.
• Always replace any spring lock washers, splitpins and other fasteners removed during thework with new parts when reassembling theequipment.
• Check the general condition of the operatingmechanism and recharge the spring energystorage mechanism.
Prior to functional testing, switch the breaker offand
• move it into the test position (withdrawablebreaker) or
• isolate the outgoing feeder (with stationarymounted breakers).
Note:
Isolate and secure the working area in accor-dance with the safety regulations specified byDIN VDE/IEC.
Scope of functional testing:
• Perform several switching operations under no-load, above all with circuit-breakers seldomoperated in normal service.
• Switch off the charging motor (if fitted) anddischarge the spring energy storage mechanismby ON/OFF switching operations.
• Examine visual the condition of the lubrication onrotary bearings, sliding surfaces, etc.
• Check the proper mechanical/electrical sequenceof the individual functions.
8.2.3 Breaker pole
No inspection of the breaker pole above andbeyond the stipulations of section „Inspection,switching devices in general“ is necessary.
8.2.4 Withdrawable assembly
• The inspection should always include a visualexamination of the withdrawable part assembly.Special attention is to be paid to those partswhich may possibly be damaged by improperhandling. (See section “Inspection/Circuit-breaker in general“.)
• Visual checking of the isolating contact system.We recommend turning the contact systemalternately in order to clean the inner contactpoints.
The contact points should be cleaned if signs ofimpermissible overheating (discoloured surface)are visible (see section “Repairs“).
• The interlock conditions and the ease ofmovement of the lock and release device are tobe checked as described under “Repairs“.
When checking the interlock conditions, it isessential to ensure that no force is used.
Maximum torque 25 Nm!
8.3 Servicing
8.3.1 Switching devices in general
If cleaning is found to be necessary duringinspections as set out in „Inspection, switchingdevices in general“, the following procedure is tobe adopted:• Prior to cleaning, the working area is to be
isolated and secured against reclosing where
44
• Perform comprehensive mechanical and electricalfunctional tests. Observe the instructions onsetting.
• Ensure that the bolted joints at the contactlocations of the conductor bar system and theearthing connections are tight.
Note:
Above mentioned work may only be performed bythe after-sales service personnel of ABB or ade-quately qualified personnel.
8.3.3 Breaker pole
The breaker pole with the vacuum interrupter ismaintenance-free up to reaching the permissiblenumber of vacuum interrupter operating cycles inaccordance with section „Permissible number ofvacuum interrupter switching operations“.
The working life of the vacuum interrupter isdefined by the sum current limit corresponding tothe equipment data in individual cases inaccordance with section „Permissible number ofvacuum interrupter switching operations“:
• When the sum current limit is reached, thecomplete breaker poles are to be replaced.
Note:Dismantling and Replacement of the completebreaker poles should only be carried out byABB after-sales service personnel or by speciallytrained personnel, particularly as proper adjust-ment is necessary.
For testing the vacuum without dismantling thecircuit-breaker you may use:
• Vaccuum tester VIDAR, from ProgrammaElectric GmbH, Bad Homberg v.d.H.
The following test values have to be set forchecking of the internal interrupter chamberpressure with the VIDAR vacuum tester:
Rated voltage of DC test voltagethe circuit-breaker
12 kV 40 kV
17.5 kV 40 kV
24 kV 60 kV
Testing must always be performed with the deviceswitched off:
• 12 to 24 kV: with rated contact distance
• 36 kV: with additional provisions(obtainment of information frombreaker manufacturer necessary)
Procedure for vacuum interrupter testing forstationary mounted switching devices:
• Isolate and secure the working area inaccordance with the Safety Regulations toDIN VDE / IEC.
• Open the circuit-breaker.
• Earth all poles of the circuit-breaker on one side.
• Connect the earthed test lead of the the VIDARvacuum checker conductively to the stationearth.
• Connect the high voltage test lead of the VIDARvacuum checker with phase L1 of the unearthedpole side and test the vacuum interrupterchamber with the circuit-breaker contact gapopen. Repeat for phases L2 and L3.
Note:Connected cables may lead to a “detective“indication on the vacuum checker as a result oftheir cable capacitance. In such cases, the cablesare not be removed.
8.4 Repair
8.4.1 VD4 circuit-breaker run-on block
In case of any irregularity in the area of the innercontrol mechanism and of the charging function ofthe stored-energy spring mechanism, the run-onblock disables the immediately subsequentswitching operation.
This is a protective measure to prevent damage tothe circuit-breaker
Release of the run-on block is described ininstruction manual BA 383/E.
8.4.2 Replacement of circuit-breaker parts andaccessories
Only remove and reassemble circuit-breaker partsand accessories when the breaker has been switchedoff and the working area is to be isolated andsecured against reclosing. The spring energy storagemechanism must be discharged.
All supply voltage sources must be disconnectedand secured against reclosing during the removaland installation work.
8.4.3 Touch up of surfaces
• Sheet steel parts, painted:
– Remove rust, e.g. with a wire brush.
– Grind off paint coat and degrease.
– Apply anti-rust primer and top coat.
– Use top coat paint in the standard colourRAL 7035.
• Sheet steel parts, with zinc surface andpassivated functional parts:
– Remove white rust with a wire brush orcleaning pad (e.g. Scotch-Brite white).
– Remove loosely adhering particles with a drycloth.
– Apply zinc spray or zinc dust primer.
• Functional parts, phosphated:
– Remove rust with a wire brush or cleaning pad(e.g. Scotch-Brite white).
45
– Clean with a dry cloth.
– Grease with Isoflex Topas NB 52.
8.4.4 Circuit-breaker in general:
• Check that the bolt connections at the contactpoints in the busbar system are tight, and thatthe isolating contact system functions correctly.
• Regrease the contact points and mechanism ofthe withdrawable part insertion system asnecessary, or, when lubrication is inadequate ormissing, thoroughly clean the areas concernedand regrease with Isoflex Topas NB 52 lubricant.
• Where required, regrease or thoroughly cleanslide plates and bearings in the panel andregrease them with Isoflex NB 52 lubricant.
8.4.5 Replacement of contact systems
(Cover illustration of „Maintenance“ section)
Remove the contact system for thoroughlycleaning as described below (Figures)
– Slide the two inner annular tension springsfacing the breaker pole to a position beside theother two outer annual tension springs, thusreleasing contact system, and remove thecontact system from contact arm.
– Fit a new contact system back to front on thethin end of arbor, and slide it forwards onto thethicker part of the shank.
– Fit arbor onto the relevant contact arm, slide thecontact system over onto the contact arm, andwithdraw the arbor.
– Check all contact fingers and annular tensionsprings for perfect fit.
Note:
The set installation position of contact arms mustnot be changed by the improper use of force.
8.4.6 Replacement of the withdrawable assembly
(Figures 8/7, 8/10 and 8/11)
• Disconnect plug connector 8.3 (only forwithdrawable assembly of type B)
• Remove interlock rod 46.5 with pin 46.4 fromthe withdrawable assembly
• For motorized withdrawable assemblies,remove the two socket head bolts which areaccessible from below the assembly
• Unbolt the circuit-breaker from the withdrawableassembly (4 x M12 bolts)
• Mount the circuit-breaker on a new with-drawable assembly in the reverse order, usingnew circlip and special pliers for pin 46.4
• Check the setting of interlocking rod 46.5:
– Turn spindlel 4 anti-clockwise to the stop forthe disconnected position:
The distance between lever 46.3 and cam46.2 must be 2+1 mm.
The distance between roller 46.1 andblocking bracket 46.8 must be 0.2-0.5 mm.
– Turn spindle 4 clockwise to the stop for theservice position:
The distance between lever 46.3 and cam46.2 must be 2+1 mm.
The distance between roller 46.1 andblocking bracket 46.8 must be 0.2-0.5 mm.
– Loosen bolts 46.7 or 46.9 for any necessaryadjustment.
8.5 Testing withdrawable parts with a VD4 typecircuit-breaker
When functional tests are carried out onwithdrawable parts, compliance with the con-ditions listed below should also be checked. Inthis context, a distinction should be madebetween two types of the devices for the VD4withdrawable part:
• Type A: Withdrawable assembly without inte-grated auxiliary switches (manual operationonly).
• Type B: Withdrawable assembly with integratedauxiliary switches (manual or motorizedoperation).
8.5.1 Motor-driven withdrawable parts
(non-standard)
Carry out testing of motor-driven withdrawableparts in the same way as for manually operatedwithdrawable part:
• Turn off the supply voltage (m.c.b.), since themotor could otherwise be braked electrically.
• Turn hand crank 5 in the required direction.
Note:
When the withdrawable part moves, the motorturns. The motor functions in such a case like agenerator, i.e. it can lead to reverse voltages in theterminals.
8.5.2 Checking the correctness of dimensional settings
(Figures 8/7 to 8/11)
1. The distance between lever 46.3 operated bylink rod 46.5 and plastic cam 46.2 should be2+1 mm. If adjustment is required, release thetwo bolts 46.6 and 46.7. Deviations from thespecified value can have the following effects:
• Dimensions too large: blocking system for thedrive spindle deactivated.
• Dimensions too small: proper action of theelectrical interlock no longer guaranteed.
46
2. The distance between roller 46.1 and angle lever46.8 should be 0.2-0.5 mm when the circuit-breaker is closed.
If adjustment is required, release the two bolts46.7 and 46.6.
8.5.3 Checking auxiliary switch settings on type Awithdrawable parts
(Figure 8/7 )
Compliance with the interlock conditions in theareas of the test/disconnected position and theservice position is ensured by auxiliary switch -S6,located in the breaker housing and factory-set.
In test operations, the withdrawable part must bemoved by hand with the crank fitted.
1. Settings in the area of the test/disconnectedposition
• Move the withdrawable part out of the test/disconnected position towards the serviceposition with a few turns of the crank.
• Slowly move the withdrawable part back tothe stop.
Auxiliary switch -S6 must then operate whenthe hand crank has a remaining angle of ≥ 60o
of turn to reach the stop.
• Slowly insert the withdrawable part from thetest/disconnected position towards theservice position until auxiliary switch -S6 justoperates.In this position, it must still just be possible tomove closing push rod 11.1. For this test, thefunction of the blocking magnet -Y0(dependent on the order) must be deactivatedmanually.
This condition ensures that the electricalinterlock takes effect before the mechanicalinterlock in the motion sequence involved.
2. Settings in the area of the service position
• Move the withdrawable part out of the limitposition towards the test/disconnectedposition with a few turns of the crank.
• Slowly move the withdrawable part forwardsagain to the stop:
Auxiliary switch -S6 must then operate whenthe hand crank has a remaining angle of ≥ 60o
of turn to reach the stop.
8.5.4 Checking auxiliary switch settings on type Bwithdrawable parts
(Figures 4/3 and 8/7)
Compliance with the interlock conditions in thetest/disconnected and service position areas isensured by position signalling switches -S8 and-S9 located in the withdrawable assembly andfactory-set.
In test operations, the withdrawable part must bemoved by hand with the crank fitted with the motorpower switched off.
1. Settings in the area of the test/disconnectedposition
• Move the withdrawable part out of the test/disconnected position towards the serviceposition with a few turns of the crank.
• Slowly move the withdrawable part back tothe stop.
Auxiliary switch -S8 must then switch overjust before the stop is reached.
• Slowly insert the withdrawable part from thetest/disconnected position towards the serviceposition until auxiliary switch -S8 just operates.
In this position, it must still just be possible tomove closing push rod 11.1. For this test, thefunction of the blocking magnet -Y0(dependent on the order) must be deactivatedmanually.
This condition ensures that the electricalinterlock takes effect before the mechanicalinterlock in the motion sequence involved.
2. Settings in the area of the service position
• Move the withdrawable part out of the limitposition towards the test/disconnectedposition with a few turns of the crank.
• Slowly move the withdrawable part forwardsagain to the stop:
Auxiliary switch -S9 must then switch overjust before the stop is reached.
8.5.5 Checking the direction of rotation of the travelmotors on motor-driven withdrawable parts
• Move the withdrawable part by hand into acentral position between the test/disconnectedposition and the service position.
• Remove the hand crank.
• Switch the supply voltage for the travel motor on.
• Use the local electrical controls to check that thewithdrawable part moves in the correct direction.
Caution:
Do not allow the withdrawable part to run upagainst a block when the travel direction isincorrect! Switch the motor power off immediately(the travel process functions electrically by a seal-insystem with limit position switch-off).
There may be a danger of injury when the door isopen!
8.5.6 Testing of interlock conditions
(Figures 7/1, 7/2 and 8/7)
The testing procedures for type A and type Bwithdrawable parts are identical.
1. The withdrawable part must only be movablefrom the test/disconnected position into theservice position when the circuit-breaker is openand the earthing switch is open.
47
Check the following conditions individually:
• With the circuit-breaker closed, insertion ofthe withdrawable part towards the serviceposition must be blocked after only half a turnof the crank in the clockwise direction, andthe travel motor on motor-operatedwithdrawable parts must not be capable ofbeing switched on.
• With the earthing switch closed, insertion ofthe withdrawable part towards the serviceposition must be blocked after only twoclockwise turns of the crank, and the travelmotor on motor-operated parts must not becapable of being switched on.
Do not use force (max. torque 25 Nm)!
2. The withdrawable part must only be movablefrom the service position into the test/disconnected position with the circuit-breakeropen.
Check this condition as follows:
• With the circuit-breaker closed, withdrawalmovement of the withdrawable part must beblocked after only half a turn of the crank inthe anti-clockwise direction, and the travelmotor on motor-operated withdrawable partsmust not be capable of being switched on.
3. Closing of the circuit-breaker must only bepossible when the withdrawable part is in thedefined test/disconnected position or serviceposition.
The control wiring plug 8.1 must previously havebeen inserted.
Check this condition as follows:
• It must not be possible to close the circuit-breaker with the withdrawable part in anyposition between the test/disconnectedposition and the service position.
• Enabling of switching when the withdrawablepart moves into the service position iseffected electrically by operation of auxiliaryswitch -S6 in the breaker housing (for type A),or of auxiliary switch -S9 in the withdrawableassembly (for type B), and mechanicallyslightly earlier; the latter corresponds to aposition approximately half a turn of the crankbefore stop.
• For motion into the test/disconnectedposition, the same enabling conditions applyanalogously, in this case by means of auxiliaryswitch -S6 in the breaker housing(for type A)or the auxiliary switch -S8 in the withdrawableassembly (for type B).
4. It must only be possible to open the circuit-breaker (manually) when the withdrawable partis in the service position or test/disconnectedposition and the control voltage has failed.
Check this condition.
5. Withdrawable parts with order-related blockingmagnet -Y0 may not be moved in case of controlpower failure, or when there is no control power.Do not forcibly move blocked withdrawableparts! The blocking magnet -Y0 is only presenton manually operated withdrawable parts.
Releasing the blocking magnet -Y0.
• Remove front plate 9.2,
• Disengage blocking magnet -Y0 by pulling themagnet armature,
• While doing so, turn crank 5 about one halfturn (either direction of rotation is permissible).
The blocking magnet is only active in the testposition and service position. In intermediatepositions it has no effect.
6. Disconnection of the control wiring plug 8.1 aswell as later insertion must be blocked in thewithdrawable part’s service position.
Check this condition.

9 Application of the X-ray regulationsOne of the physical properties of vacuum insulationis the possibility of X-ray emissions when the con-tact gap is open. The specified test performed bythe Physikalisch-Technische Bundesanstalt (PTB)in Braunschweig demonstrates that the local dos-age output of 1 µSv/h at a distance of 10 cm fromthe touchable surface is not exceeded when therated voltage is applied.
The results are as follows:
• Testing of the switching device or the vacuuminterrupter to VDE 0671 part 100 or IEC 62271-100 at the relevant rated power frequencywithstand voltage may only be performed bytrained personnel observing the stipulations of theEU basic standard (Stipulation 96/29/Euratomof the senate from 13 May 1996 (ABI.L 159 from29 June 1996)).
• Application of the rated power frequency with-stand voltage specified for the switching deviceby VDE 0671 part 100 or IEC 62271-100 iscompletely safe.
• Higher voltages than the rated power frequencywithstand voltage or DC test voltage specified inVDE or IEC standards must not be applied!
• The containment of the above mentioned localdosage output with the vacuum interrupter in theopen position is dependent on maintenance ofthe specified distance between the contacts(which is automatically ensured with correctmechanism function and force transmission).
• Safety clearances must be maintained.
