Switching duties andoperating mechanisms

The switching duties of thevacuum circuit-breaker are de-pendent, among other factors, onits type of operating mechanism.Three operating mechanism ver-sions are available:

• Motor operating stored-energymechanism

– For auto-reclosing (K),– For synchronization and

rapid load transfer (U)

• Manual operating stored-energy mechanism

– For auto-reclosing (K)

• Manual spring-operated me-chanism (= spring CLOSED,stored-energy OPEN)

– Not for auto-reclosing (K)– For normal closing and– For storage of one opening

operation

Further operating mechanismfeatures

• Located outside the switch-gear vessel in the operatingmechanism box and behindthe control board

• Stored-energy springmechanism for 10000operating cycles

3AH vacuum circuit-breaker

Operating mechanismfunctions

Motor operating mechanism 1)

(M1 *)

In the case of the motor oper-ating mechanism, the closingspring is charged by means ofa motor and latched in thecharged position (the “springcharged” indication is visible).Closing is effected either bymeans of an ON pushbutton ora closing solenoid. The closingspring is recharged automati-cally (for auto-reclosing).

Manual operating stored-energy mechanism

The closing spring is chargedby means of the hand crank sup-plied until latching of the closinglatch is indicated(= “spring charged” indication).

Subsequently the vacuumcircuit-breaker can be closedeither manually or electricallyand the closing spring can berecharged manually. The “possi-bility to close” is thus storedonce more (for auto-reclosing).

Manual spring-operatedmechanism(= spring CLOSED, stored-energyOPEN)

The closing spring of the vacuumcircuit-breaker is charged bymeans of the hand crank sup-plied until the vacuum circuit-breaker closes. Subsequentlyeither manual or electrical open-ing is possible.

Vacuum circuit-breakers withspring-operated mechanism arenot suitable for auto-reclosing.

Trip-free mechanism

The vacuum circuit-breakeris fitted with a trip-freemechanism.

Standards

The 8DH10 switchgearcomplies with the relevantstandards and specificationsapplicable at the time oftype tests.

In accordance with theharmonization agreementreached by the countries of theEuropean Community, theirnational specificationsconform to the IEC standard.

Dielectric strength

See also Catalog HA 40.1“Standards”.

Terms

“Make-proof earthing switches”are earthing switches withshort-circuit making capacityaccording to IEC 62 271-102/VDE 0671-102.

Protection against solid for-eign objects, electric shockand ingress of water

The switchgear types 8DH10fulfill acc. to the standards

the following degrees of pro-tection (for explanations re-garding the degrees of protec-tion, please refer to Catalog HA40.1, page 38)

Climate and ambientconditions

8DH10 switchgear types arefully enclosed and insensitive toclimatic conditions.

• Climatic tests fulfilled inaccordance with IEC 60 932(report)

• All medium-voltage devices(except for HV HRC fuses)are installed in a gas-tight,welded stainless steelswitchgear vessel which isfilled with SF6 gas

• Live parts outside the switch-gear vessel are provided withsingle-pole enclosure

• At no point can creepagecurrents flow from high-voltage potentials to earth

• Operating mechanism partswhich are functionally impor-tant are made of corrosion-proof materials

• Bearings in operating mech-anisms are designed as dry-type bearings and do notrequire lubrication

• Suitable instrument trans-former designs

• Plug-in busbar system,insulated or screened

• Operating conditions accord-ing to IEC 62 271-200,among other, relative airhumility: 95 %(24-hour mean value)

• Metering panel ME1(air-insulated) according toIEC 60 694: “Normal operat-ing conditions”

Type of service location

8DH10 switchgear can beused as indoor installations inaccordance with IEC 61 936(Power installations exceeding1 kV AC) and VDE 0101:

• Outside lockable electricalservice locations at placeswhich are not accessible tothe public. Enclosures ofswitchgear can only beremoved with tools.

• Inside lockable electricalservice locations. A lockableelectrical service location is aplace outdoors or indoors thatis reserved exclusively forhousing electrical equipmentand which is kept under lockand key. Access is restrictedto authorized personnel andpersons who have been prop-erly instructed in electricalengineering. Untrained orunskilled persons may onlyenter under the supervision ofauthorized personnel or prop-erly instructed persons.

Internal arc classification(option)

The possibility of arc faults ingas-insulated switchgear type8DH is improbable and a merefraction of that typical of earlierswitchgear types, due to:

• Use of gas-filled switchgearcompartments

• Use of suitable switchingdevices such as three-position switches with make-proof earthing switch

• Logical mechanical interlocks

• Use of metal-coated voltagetransformers and three-phasering-core current transformers.

Optionally, switchgear type8DH can be designed with in-ternal arc classification:

• Internal arc classification IAC

• Type of accessibility A(for authorized personnelonly)

• Accessible sides– Side F (front)– Side L (lateral)– Side R (rear) as an option for

switchgear with pressureabsorber

• Arc test current up to 21 kA /1 s
