断路器

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

电力系统中使用断路切除无功补偿用并联电容时,容易产生燃过电压,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.

测试仪在测试高压断路灭弧室时具有操作及安装简便、测试结果可信等优点。
