VS1 (ZN63A) type indoor high-voltage vacuum circuit breaker is the rated voltage 12KV, 24KV, three-phase AC 50HZ indoor high-voltage switchgear, equipped with the motor ---- spring operating mechanism, can realize electric and manual switching and closing, can be loaded into the hand switchgear, can also be matched with the fixed switchgear. The fixed circuit breaker can be added with special interlock to meet the needs of fixed cabinets such as XGN2 and GG1A. At the same time, 24KV vacuum circuit breaker can also be applied to 12KV distribution system in plateau areas (up to 4000 meters above sea level).
Main features of VS1-12KV indoor high voltage vacuum circuit breaker:
1. It is convenient for adjustment due to the vacuum circuit breaker adopt the design of arcing chamber is located on the upper, the operating mechanism is located on the down.
2. It adopt the structure of combination of air and organic composite insulating material.
3. Simple spring operating mechanism, 10000 operating times.
4. Smooth and good self-locking performance due to lead-screw propulsion mechanism.
