摘要
本文通过分析一起220kV线路的不正确动作行为,指出日常防跳功能试验方法的缺陷,在分析防跳回路后,提出了一种断路器防跳功能试验的新方法。
By analyzing an incorrect operation action of 220 kV line, the defects of routine test method of trip proof func tion were found. A novel test method of circuit breaker trip proof function was put forward after analyzing the trip proof circuit.
