General DescriptionVA and VAA vacuum circuitbreakers are front-mounted switches for application in medium-voltage indoor switchgear. They can be fixed installations in switchgear or can be mounted on a switchgear truck, a drawing-unit truck or a drawing unit. In railway applications, vacuum circuitbreakers VXA or VXB (single-/ two-pole units respectively) are used. VXC circuit-breakers which are designed for an especially high number of mechanical and electrical switching operations are suitable to operate electric melting furnaces. Vacuum circuit-breakers are capable of performing all switching operations and tasks encountered in industrial plants and distribution networks or in railway applications, especially for operation of:

short-circuit currents

underground and overhead

lines

motors

transformers

generators

capacitors

Essential Features ■ High number of mechanical and electrical switching operations ■ No critical current range ■ Long service life ■ High switching capacity reserve ■ Minimum maintenance

VA Mechanical design

ApplicationVacuum circuit-breakers are designed as front switches. The three-pole VA and VAA vacuum circuit-breakers master all switching cases occurring in medium-voltage systems. The VXA and VXB vacuum types satisfy specific circuit-breaker requirements. VXA vacuum circuit-breakers are single-pole, VXB types feature two poles, both types being mainly suited for railway applications. Threepole vacuum circuit-breakers VXC are used for extremely high operating frequencies, as are required e.g. for furnaces. Vacuum circuit-breakers can be fixed installations in switchgear or can be mounted on a drawing unit, a drawing-unit truck or a switchgear truck.

Design and method of operationEach of the switch poles with 1 interrupter chamber per phase is fastened to a common base frame with 2 cast-resin post insulators. All drive components, auxiliary and release devices are located in the base frame which is designed as a closed housing. Vacuum circuit- breakers can be equipped with control switches, auxiliary releases, secondary releasesand undervoltage releases, as required.Vacuum circuit-breakers are equipped with a snap-action mechanism with manually or electrically operated spring charging motor and can beequipped at choice with a reclosing facility (auto-reclosure).Power transmission between the energy-storing device and the switch poles which is required for switching ON and OFF is effected by means ofan operating rod made of highquality glass-fibre reinforced insulating material which is largely free of constraints while the vacuum circuit-breaker is ON.

VA

Pole SectionThe pole section is of extremely robust design. The solid support provides for a suspension free of external forces for the interrupter chamber. Due to this statically closed support system, the axial forces produced on closingand opening only act on the contact system, whereas the vacuum interrupter chamber remains free of constraints. The power transmission acts from the contact spring onto the moving contact via a lever system with pendulum rod to make sure the closing and opening forces are applied in precisely axial direction.

Drive MechanismThe drive mechanism has been designed as a making/breaking spring mechanism. The closing spring of the making storedenergy mechanism is charged either via an electric motor installed in the drive housing or by hand using an insertable crank. If the electric motor‘s power supply fails, the spring can still be charged at any time via the crank. The openingspring is charged during the closing operation (ON). Once closing is concluded, the closing spring - now discharged - can be charged again by the spring-charging motor automatically or by hand. In this state, the drive mechanism is ready to perform the operating sequence O–t’–CO. Thechargedclosing spring can eitherbe released by hand, by actuation of the ON pushbutton, or by a shunt closingrelease installed in the drive box. The opening procedure is initiated by actuation of the OFF pushbutton or via a shunt opening release, an undervoltage release or a secondary release.

VA Optional equipment

Releases

Auxiliary release(Shunt releases)The coil of the auxiliary release is supplied with exciter voltage from an auxiliary supply source via a release contact. Pulsing can be initiated by hand, via control switches, overcurrent releases or undervoltage releases.If AC voltage is supplied, a rectifier located in the switch housing is installed upstream of the coil. As the coil is designed for short-term excitation only, the exciter circuit is routed via an auxiliary switch contact controlled by the circuit- breaker shaft, thus - once released - interrupting the current circuit.

Secondary release(Transformer-operated release) Secondary releases are used for automatic release of switching devices in case of short-circuits and overcurrent. Once the protector has reacted, the release is excited by the transformer current, thus causing the switch to be tripped. These releases are supplied for transformer secondary currents of 0.5 A and 5 A.

Undervoltage releaseUndervoltage releases are suppliedby the auxiliary sourcepermanently.Whenever the auxiliary current is interrupted or its voltage drops essentially, the switching device is tripped straight away. If the undervoltagerelease is supplied by a voltage transformer located downstream of the switch, a holding device can be installed which prevents the switch frombeing released, when it is not yet closed completely.

Control Switches

Auxiliary switchAuxiliary switches are always actuated directly by the switch shaft via an intermediate linkage, their position always corresponding to that of themain contacts. The circuitbreakers are equipped with an auxiliary switch with 12 contact elements on principle; 8 contact elements have been assigned to the internal switching operation (see circuit diagrams).For additional current circuits, up to 8 contact elements can be arranged additionally. Moreover, the switching device can be equipped with a mechanically time-delayed contact element (1-pole pulse contact, T 50 ≥ ms).

Push switchesThe push switches are snapaction switches mounted to the drive mechanism. Unlike auxiliary switches, push switches are not necessarily dependent on the switching device‘s position, but are actuated e.g. via cams or via various elements attached to the switch. The control switches are wired to the terminal strip; on request, a plug-andsocket connection (with connectorand connector base) is also available.

Chassis FramesChassis frames for circuitbreakers are manufactured of folded sheet metal or sectional steel, and are equipped with castors. Binding dimension drawings are available on request.

Surge ArrestersSurge arresters must be used to protect the high-voltage motor circuits against overvoltage.The following data are required to determine the surge arrester: motor rated voltage max. ambient temperature transformer neutral point earth fault duration


VA Vacuum circuit-breakerwith reclosing facility (auto-reclosure)

All vacuum circuit-breakers can be supplied with reclosing facility (KU).

Method of operationIf a short-circuit occurs, an overcurrent relay issues a pulse to the shunt opening release, after expiry of the preset instantaneous zone, switching the circuit-breaker OFF.Once the preset dead time has expired, an ON command is issued to the shunt closing release via a NO contact of the auto-reclosing relay.If the short-circuit is still present, another OFF command is issued by the overcurrent relay, and the circuit-breaker is switched off for good. The auto-reclosing relay does not issue another ON command.The vacuum circuit-breaker‘s economic efficiency is based on its excellent maintenance characteristics. The interrupter chamber need not normally be replaced during the switching device‘s service life. The admissiblenumbers of switching operations at different breaking currents are indicated in the diagrams.The high value of the service life is considered in comparisons of economic efficiency with other switch principles, especially in applications requiringhigh operating frequencies. In other cases, maintenance of the drive mechanism and the expense required to this effect for electric isolationdecisively affect availability and maintenance costs. The requirement of having a single inspection of the drive mechanism after 10,000 operatingcycles or 20 years of operation means that maintenance expense is reduced to a minimum.The VXC vacuum circuit-breakers can be used for extremely high numbers of operating cycles, e.g. as furnace-type switches.After 25,000 switching operations, the drive mechanism should be checked and the vacuum interrupter chambers replaced at the same time. The mechanical service life of the VXC vacuum circuit-breaker is 75,000 operating cycles.

VA Specificationsand tests (contd.)

Vacuum tester VT 60 (Optional)The vacuum tester VT 60 can be used to verify the dielectric strength of the contact gap of the vacuum circuit-breakers.This test is also used to determine indirectly whether the vacuum interrupter chambers are subject to an inside pressure of ≤10 -2 mbar.This unit enables the operator

■ to determine easily and quickly, without disassembling the switching device, ■ without extensive testing ■ with a sufficient precision whether the vacuum level in the interrupter

chamber still satisfies the requirements.

Special features ■ Straightforward handling ■ Compact design (unit incl. case approx. in the size of a briefcase) ■ Rugged design ■ Low weight (approx. 8 kg) ■ Low cost of investment

Physical bases of the test methodThe dielectric strength of the vacuum contact gap depends on the chamber pressure „P“.Thus, the vacuum can be checked indirectly by means of voltage measurement. The test point „A“ has been arranged conveniently so that it features a sufficient distance from point „B“ (state with the chamber filledwith air), but so that the vacuum interrupter chamber is not subjected to an unnecessarily high load.

Performance of the auditAfter connecting the vacuum tester VT 60 to the circuitbreaker to be checked, the test can be performed easily and quickly:

■ Select the test voltage (40 or 60 kV) ■ Switch on power supply; the red warning lamp „Attention

□ high voltage“ lights up. ■ At the same time, turn knobs „Test“ with your left and right hands to their

stop in the direction of the arrow and wait for a few seconds for the lamps „not faulty“ or „faulty“ to light up.If the green lamp (not faulty) goes on, the test is completed, the vacuum chamber can be considered to be functional.

■ If the red lamp goes on, the test is repeated twice. If the green lamp does not go on even after the 3rd attempt, the vacuum interrupter chamber is considered to be faulty.The vacuum tester VT 60 thus permits straightforward, quick and reliable testing of highquality switching devices.

VA Electric circuit diagrams

Vacuum circuit-breakers without reclosing facility (Auto-Reclosure) Basic designThis circuit diagram shows the max. possible secondary equipment. Depending on the order volume, components shown may not be included.with terminal strip with anti-pumping relay

Devices which may be installed in the circuit-breaker depending on order specificationF 11 Shunt opening release (shunt release)F 2 Shunt closing release (shunt release)M 1 Motor to charge the energy-storing deviceS 1 Auxiliary switchS 21–S 25 Push switch actuated by energy storing deviceS 41 Push switch actuated by the buttons ON / OFFS 43 Push button actuated by the button OFFS 6 Push-button actuated by the switchgear truckV 1 DiodeV 2 RectifierX 1 Terminal strip

Charging the energy-storingdeviceAs the switch (F 101) is closed, the motor (M) is energized and the energy-storing device is charged. Once charging is finished, the push switches (S 22 and S 23) are actuated by a shaft, and the motor switchedoff.

Switching ON (Closing)Closing can be effected

■ mechanically via the button „ON“ ■ electrically via the contact element „ON“ (SOE), which excites the shunt closing release (F 2).

As soon as closing operation (ON) is terminated, the motor charges the energy-storing device, as the push switches (S 22 and S 23) are closed with the energy-storing device discharged.

Switching OFF (Opening)Opening can be effected

■ mechanically via the button „OFF“ ■ electrically via the contact element „OFF“ (SOA), which excites the shunt opening release (F 11). ■ electrically via an overcurrent relay (F 321) which excites the shunt opening release (F 11).

MessageIn closed state („ON“), the pilot lamp „ON“ (HOE) is lit, in open state („OFF“), the pilot lamp „OFF“ (HOA) is lit. The „malfunction“ signalling relay (KOS) only receives a switching pulse via the passing contact (239/230) from the auxiliary switch of the circuit-breaker (S 1) if tripping is effected by the overcurrent relay (F 321), as in case of manual operation, either the NC contact of the push switch (S 41) of the button„ OFF“ opens, or, in case of electrical operation, the NC contact of the contact element „OFF“ (SOA).The „malfunction“ signalling relay features a self-holding contact, but can be de-excited via its shut-down element (SOR). The „malfunction“ pilot lamp (HOS) is energized via the „malfunction“ signalling relay.

The operations „charging the energy-storing device, switching ON, switching OFF and signalling“ are effected as in case of vacuum circuit-breakers without reclosing facility.

Reclosing facility (auto-reclosure)If a short-circuit occurs, the overcurrent relay (F 321) issues a pulse to the shunt opening release (F 11 ), after expiry of the preset instantaneous zone, switching the circuit-breaker OFF.Once the preset dead time has expired, a ON command is issued to the shunt closing release (F 2) via a NO contact of the auto-reclosing relay (F 371).If the short-circuit is still present, another OFF command is issued by the overcurrent relay, and the circuit- breaker is switched off for good. The auto-reclosing relay does not issue another ON command.
