Product details
Overview of VS1-12 series indoor fixed high-voltage vacuum circuit breaker:
The VS1-12 series indoor fixed high-voltage vacuum circuit breaker is a three-phase AC 50Hz indoor switchgear with a rated voltage of 12kV. It can be used for control and protection of industrial and mining enterprises, power plants and substations, electrical facilities, and is suitable for frequent operation in places.
By integrating the operating mechanism with the circuit breaker body, it can be designed as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit for use. The main circuit section can be equipped with integral sealing columns to achieve miniaturization, high reliability, and maintenance free of circuit breakers. It can be used with KYN28A-12 (GZS) and other mid mounted handcart style switchgear, and can also be used with XGN series fixed switchgear.
VS1-12 series indoor fixed high voltage vacuum circuit breaker normal daily use environment:
1. Environmental temperature: not higher than 40C, not lower than -10C (allowed for storage and transportation at -30C);
2. Altitude: not exceeding 1000m (if higher altitude is required, the rated insulation level will be correspondingly increased);
