断路器

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,严重影响并联电容运行。

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

真空仪在压真空断路器真空灭弧室真空时具有操作及装简便、结果可信等优点。
