摘要
针对电力系统近些年所使用的F-C真空接触器型开关出现的操作过电压的现象,对F-C型开关的多种过电压的产生原因和危害程度进行分析,并提出了相应的解决方法。
Several kinds of the overvoltage appearance of F-C type switch and their danger degrees are analyzed according to the operation phenomena of inducing overvoltage of F-C vacuum-direct-contact-type switch used in electric power systems in recent years. And the corresponding methods to solve these problems are presented here.
