Switchgear Type 8DH10, up to 24 kV, Gas-Insulated, Extendable
Features
• According to IEC 62 271/VDE 0671-100(standards see page 41)
• Application of all 8DH10switchgear in hermeticallysealed vessel in conformitywith the system
• Climate-independent vacuuminterrupter poles in thegas-filled switchgear vessel
• Maintenance-free for indoorinstallation according toIEC 60 694/ VDE 0670-1000(standards see page 41)
• Individual secondary equipment
• A metal bellows is used forgasketless separation of theSF6-insulation and the operat-ing mechanism – as alreadyused with success for over100000 vacuum interrupters
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.
1) Motor rating at24 V to 220 V DC: 350 W110 V and 230 V AC:400 VA
2) With closing solenoid

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
