Product Description

BKV3(VS1)-12KV vacuum circuit breaker

BKV3-12 indoor H.V. vacuum circuit breaker is an indoor switchgear with three-phase, rated voltage of 12kV, control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and for frequent operation place adopting VET operating mechanism and circuit breaker integrated design can be used as a fixed installation unit can also be equipped with special advance mechanism, the composition of handcart unit used some of the main circuit can use the whole solid seal post with high reliability, maintenance-free, in order to achieve smaller circuit breakers, can be equipped with KYN28A 12 and other handcart switch cabinet. In the home it can also be used with fixed XGN switchgear.

VS1-Series circuit breaker features high stability and high reliability

In terms of mechanisms, VS1-Series vacuum circuit breakers are given special optimization to transmission parts. Modular spring mechanisms have such advantages as convenient maintenance, short power-off maintenance, high versatility of parts, and boast better compatibility with vacuum interrupters which greatly improves the technical parameters and delivers more excellent performance.

Secondary circuit

VS1-Series vacuum circuit breakers adopt modular design for their secondary control circuit boards. The electric connection of the mechanisms employs high-grade self-fastener plugs, which both facilitates replacement and ensures reliable electrical connection * High-performance oil buffer

High-performance oil buffer

High-performance breaking buffer can markedly reduce the overshoot and rebounding amplitudes of the moving contact of a vacuum circuit breaker in breaking thus avoiding the loss of mechanical endurance due to partial over fatigue of vacuum interrupter bellows resulting from moving contact overshoot. As the rebounding amplitudes of the moving contact reduces, No re-ignition and restrike is found during the switching capacitor bank test
