Vacuum Circuit Breaker(VCB)12KV 24KV 36KV Fixed type VS1 12/630 VCB

Product Description

BKV3(VS1)-12KV vacuum circuit breaker

VS1-Series embedded pole. vacuum circuit breakers are applicable to 12kV, three-phase AC 50Hz indoor switchgear and can serve as protection and control units for industrial and mining establishment transformer substation equipment. With modular and independent-frame design for their spring operating mechanisms, VS1-Series circuit breakers can operate with XGN15-12(24) mid-set and fixed switchgear. These circuit breakers are subject to both fixed installation and assembly with truck as a handcart unit

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.

Applicable standards

1EC62271-100 High-voltage switchgear and control-gear-Part 100: Alternating-current circuit-breakers

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
