VS1 10kV 12kV Indoor Circuit Breaker Spring Operating Mechanism
VS1 -12 series type indoor high voltage vacuum circuit breaker is rated voltage 12kV, three-phase AC 50Hz/60Hz Indoor high-voltage switchgear, applied for power stations, substations, and industrial and mining enterprises to control or protection transmission and distribution systems, specially for the important high altitude breaking load and frequent operation place.
The VS1 spring operating mechanism has simple structure and reliable action. Product parts of different specifications have a great versatility. Because the mechanism is independently developed by us, we can make special products subjest to different requests from users.
Circuit breaker manufacturing accordance with our national standard GB1984-2003 <AC high voltage circuit breakers>, DL / T403-2000<3.6 ~ 40.5kV Indoor Vacuum Circuit Breaker ordering technology>; and the related IEC standards And reliable interlock function.
Circuit breaker operating mechanism for the spring energy storage type, can use AC and DC energy storage operations, can also be used manually.
Circuit breaker can also be equipped with long life permanent magnetic actuator, mechanical life can reached 60000 times, can be used for extremely frequent operation place,
Circuit breaker designed to repackage the structure before and after, both can be used as a fixed installation unit, Can also be equipped with the chassis as used in the mounted unit.
The spring operating mechanism is mainly composed of seven mechanical mechanisms
1. Motor: convert electrical energy into mechanical energy
2. Reduction gearbox: reduce speed and increase output torque
3. Eccentric wheel: rotate at low speed into reciprocating linear motion
4. Ratchet: stored energy (energy storage process)
5. Cam: Instantly release energy
6. Four-link mechanism: keep closed position, open, trip
7. Accessories (closed loop, jump loop, position indicator, auxiliary contacts, etc.
