VS1-12 Indoor high-voltage vacuum circuit breaker/fixed type|Hongtuo Transformer Co., Ltd

summary:

VS1-12 series indoor fixed high-voltage vacuum circuit breaker is a three-phase AC 50Hz indoor switchgear with rated voltage of 12kV, which can be used for the control and protection of industrial and mining enterprises, power plants, substations and electrical facilities, and is suitable for frequent operation places. The operating mechanism and the circuit breaker body are integrated, which can be designed as a fixed installation unit, or can be equipped with a special propulsion mechanism to form a handcart unit for use. The main circuit part can adopt the integral fixed pole pole to realize the miniaturization, high reliability and maintenance-free of the circuit breaker. It can be equipped with KYN28A-12 (GZS) and other central handcart switch cabinets, and the fixed type can also be used with XGN series fixed switch cabinets.
