Components
Drive unit
Essential features
• Single-shaft system with single helical spring for closing (ON) and opening (OFF)
• Optimum adaptation to the small contact travel of the vacuum inter-rupters
• Minimum energy reqirement
Description
The new vacuum circuit-breaker ge-neration has optimised drive kine-matics thanks to the use of state-of-art vacuum interrupters.Method of operation: The energyfor a complete operating cycle canbe stored in the helical spring. Camdiscs control the closing and ope-ning movements of the vacuum in-terrupters. After closing, the springcharging can be continued, whichsaves the energy for a completeauto-reclosing cycle.
The drive is supplied in both stan-dard models as hand-operatedspring mechanism FH 2-01 or as motorised spring mechanism FK 2-01. Appropriate interlockspreclude faulty operation.
Besides the local mechanical actua-tion of the tripping elements byhand, electric remote control or pri-mary relay actuation of the drives isalso possible.

Pole section
The supporting component of thecomplete pole section is the polehousing of multifunction design. Itserves amongst other things as amechanical support for the upperand lower terminal contacts whichsupport the vacuum interrupter freefrom mechanical stress. There arethus no ”bridges“ of insulating ma-terial between the phases.
We were able to minimise the num-ber of single parts by integrating alarge number of functions in thepole housing.

Description of secondaryequipment
Releases
Auxiliary release (Shunt release)
The solenoid of the auxiliary releaseis excited via auxiliary energy sup-ply and tripping contact can beinitiated by hand, via an indepen-dent switch, an overcurrent releaseor an undervoltage release. Whenconnected to A.C. supply, the coil issupplied with voltage via a rectifierinstalled in the drive housing. Aftertripping has been accomplished,the solenoid is de-energised.
Indirect overcurrent release (CT operated)
Indirect overcurrent releases areused to trip switching devices auto-matically in case of short-circuitsand overcurrent. When the protec-tive system reacts, the release is ex-cited by the transformer current,causing the switch to be tripped.These releases are supplied fortransformer secondary currents of0.5 A, 1 A and 5 A.
Under-voltage release
Under-voltage releases are perma-nently applied to auxiliary voltage.When the auxiliary circuit is inter-rupted or the voltage drops excessi-vely, the switching device is trippedwithout delay.
Auxiliary switches
Auxiliary switches
Auxiliary switches are always ac-tuated directly from the switch shaftvia a linkage, i.e. their position al-ways coincides with that of themain contacts. Circuit-breakers areequipped with an 8-pole auxiliaryswitch.
Additional auxiliary switches canbe fitted on request.
Electronic pulse stretcher
The electronic pulse stretcher, typeC27 900, extends the impulse dura-tion to 50 ms and offers the follo-wing advantages:- suitable for wiper contact
impulse signals > 1 ms- independent of input voltage,
i.e. 24 V – 240 V AC/DC- independent of climatic and en-
vironmental influences- constant reproduction of wiping
impulse- potential-free wiping impulse- easy retrofitting, i.e. no inter-
vention in the circuit-breaker’s mechanical system
Push switches
The p.s. are snap-action switcheswhich are mounted to the drive.
Push switches are actuated by camsor various other elements and aretherefore not positively dependingon the position of the switching de-vice. They are wired up to the termi-nal strip or on request supplied witha connector (with plug and socket).
Coding with pins in the LV connec-tor prevents racking in and closingin panels where it is not intendedfor, e.g. because of small currentcarrying capacity.
Relays
Anti-pumping relays
If the circuit-breaker is constantlysubject to simultaneous ON andOFF commands, it will return to itsOFF position after being switchedON. It remains in this OFF positionuntil the ON command is issuedanew. This prevents the switch frombeing continually switched ON andOFF (=“pumping“).
Operations counter
To count the number of operationsof the breaker, a counter has beenintegrated. The service life or theservice cycles can be determinedbased on the number of operationcycles.

Applications
Rated short-circuit-breaking currentand part-load currents
To determine the switching capacityof the various circuit-breaker types,extensive switching test series wereperformed in high-capacity test la-boratories in Germany and abroad.The tests not only focused on regis-tration of the breaking current andthe recovery voltage by oscillo-graphs, but also on determinationof other essential physical data,such as arc power, arc voltage andtime-way diagrams. These data giveaccess to extensive findings as re-gards optimum dimensioning orcontinuous technical improvements.
Unsymmetrical breaking currents
If contact separation in case ofshort-circuit in a circuit-breaker is ef-fected during the decaying DC com-ponent of the initial symmetricalshort-circuit current, the switchingdevice must withstand a currentwhose peak value is increased bythe value of the DC component asshown in the diagrams on the left.
Alternating currents with a DC com-ponent impose a higher load on theinterrupting chambers. The suitabili-ty was proven in the case of swit-ches with short opening times in thescope of particular tests.
Auto-reclosure
A very large number of system dis-turbances are short-circuits due toan arc on overhead lines, as maybe caused by thunderstorms, stormsor animals, for example. Such dis-turbances are mostly transitory andafter switching off the short-circuitcurrent, they feature a quick dielec-tric recovery so that the system canbe switched ON again after a
dead time of 0.2 to 0.3 sec. Ourswitches allow such short deadtimes between opening and closing,meaning that system operation ispractically not affected. If the short-circuit is still ”on“ when the systemis switched ON again, it is finallyeliminated by a subsequent brea-king operation.
Due to vacuum being used as di-electric, the vacuum circuit-breakerenables performing an essentiallyhigher number of switching opera-tions in quick succession than in thecase of all the other switching prin-ciples which are being used at pre-sent.
Switching of unloaded cables andoverhead lines
In case of short circuits to ground,isolated neutral systems may feature1.4 times the phase recovery volta-ge in the initial quenching phase,besides the physical processeswhich are in principle identical tothose for single capacitors.

Switching under phase oppositionconditions
The conditions within the systemwhich on principle prevail duringphase opposition are shown in thesingle-pole block diagram. The reco-very voltage is particularly high dueto the asynchronous voltage charac-teristic of the two power supplyunits.
Switching of off-load transformers
The chopped current is very low (3to 5 A), due to the materials selec-ted for our circuit-breakers. Theovervoltages to be expected onswitching off-load transformers arebelow the values which can occurwith switches following other princi-ples; thus, overvoltage limitationmeasures are normally not neces-sary.
Switching under double line-to-ground fault conditions
In this case, a maximum short-circuitcurrent results which corresponds to√3/2 times the value of the maxi-mum three-phase short-circuit cur-rent.
Switching off short-circuit currentswith very high initial rates of rise ofthe transient recovery voltage
When switching off short-circuit cur-rents with the fault location directlydownstream of high inductances(e.g. transformers), the initial ratesof rise of the transient recovery vol-tage may substantially exceed thevalues specified by DIN VDE 0670or IEC 60056. On breaking, ratesof rise of several kV/µs may occur.Mastering extremely high rates ofrise under transient conditions isone of the vacuum circuit-breaker’sspecial feature.
Switching of motors and induc-tances with air gap
When switching off low-power high-voltage motors while starting up orat standstill, switching surges occurdue to the single-phase choppingprocedure which is specific for va-cuum circuit-breakers. Due to the operating principle of vacuum cir-cuit-breakers, irrespective of type or
brand, all must be provided with asurge voltage protection via theZnO surge arresters which are parti-cularly suited for such cases.

Insulating level(tested according to IEC 60 694or EN 60 694)
HVX vacuum circuit-breakers aresuited for installation at high altitu-des. They can be used in buildingswith a low thermal insulation or lowthermal capacity, with heating orcooling, without temperature moni-toring. The heating or cooling mayfail over several days. The specifiedinsulating level values are referredto sea level (altitude: 0 m). In case of installation higher than1000 m, the reduction of the insula-tion level must be taken into consi-deration via the altitude correctionfactor (ka = correction factor).
Thus, the following applies for theselection of devices and switchgear:
