摘要
简要叙述了由一次匝间保护动作引起的发电机跳阐事件,对可能致动的因素进行分析,归结出电压互感器刀闸一相接触不良引起的电压不平衡是误动起因的结论,最后就防止类似故障的发生提出了一些意见。
Synopsis described a occurrence of protection for interturn short-circuits action causing trip of the generator,combining to proceed the analysis now, keeping similar the occurrence of accident finally putting forward some opinion and makes a conclusion that false action is caused by poor contact of transformer isolating switch.
