A break anywhere in the circuit may cause the lights in the neighbourhood to go out.

电路上断路,都会使这带的电灯熄灭。

In a10kV distribution system,when shunt ca-pacitors are switched off by vacuum circuit breakers,restrike overvoltage often occurs.

电力系统中使用真空断路器切除无功补偿用并联电容器时,容易产生重燃过电压,重影响并联电容的安全运行。

This paper introduces the working principle and blockdiagram of impulse magnet controlled discharge method that is used in the vacuity tester.

真空度测仪在测高压真空断路器真空灭弧室真空度时具有操作及安装简便、测可信等优点。
