Commonly used interrupter circuit breaker switching capacitor does not conform
High reactive power compensation device has been widely used in power systems, as reactive power compensation to improve power factor, reduce losses, stabilize the voltage has been very common, requiring a circuit breaker switching capacitor banks frequently operate 30 times a day or more, but the domestic production of vacuum
air circuit breaker 40.5kV vacuum circuit
mcb circuit breaker of basic performance reached this product development needs, usually used interrupter circuit breaker switching
Air circuit breaker does not conform to the requirements of domestic and no similar special vacuum circuit breakers, foreign using products such as ABB HD4 SF6 gas insulated to meet with, but the price is high and not environmentally friendly.
