摘要
本文介绍了一起进相试验过程中由于励磁调节器与功率柜通信丢失后跳开灭磁开关而引起失磁事故的经过,分析了事故的原因,并结合工程实例给出了进相试验较为合理的试验方法,最后针对试验方法提出了改进意见。
The article introduces the process of a case of loss excitation accident caused by communication failure between Automatic voltage regulator and rectifier cabinet and trip the field circuit breaker,which occurred in the leading power factor test,and analyzes the cause of the accident,combined with an engineering example,reasonable test method is given.Finally,puts forward suggestions for improvement of leading power factor test.
