BKV3-12GD indoor type of VCB with disconnector&grounding 12KV

BKV3-12GD series indoor high-voltage vacuum circuit breaker(3 positions) has excellent electrical and mechanical properties, reliable and stable mechanism, long life. The main circuit adopts solid sealing pole, which improves the environmental adaptability and insulation reliability of the circuit breaker. Reliable mechanical and electronic performance and extended mechanical and electronic life make maintenance-free circuit breakers possible. It can be used in 3.6-12kV power system, as a power grid equipment, industrial and mining enterprises power design protection box control unit, suitable for a variety of different nature of the load and frequent operation, multiple times to break the short-circuit current occasions. The product has a perfect mechanical and electrical interlocking device, with high operational stability and reliability, to ensure the safety of operators and equipment, to ensure the safety of electricity.

Using solid sealing pole technology.

The product adopts modular design: frame structure, integrated isolation switch, solid sealed vacuum circuit breaker, ground switch, sensor, interlock mechanism, operating mechanism as one of the high-performance miniaturized high voltage electrical products. Rotary isolation switch with visible fracture after opening.

There is a forced mechanical interlock between the isolation switch, circuit breaker and ground switch to prevent misoperation.
