摘要
在某500 kV变电站500 kV系统中,进行一次正常操作过程时,如果开关的一相机构出现问题,将有可能引发断路器失灵保护动作的情况,对此进行了探讨并提出了解决办法。
In the 500 kV power system of a 500 kV substation, a normal operation may lead to circuit breaker failure protection responding if any single- phase operation mechanism of breaker is wrong. The problem is analyzed and the measures are given to resolve it.
