摘　　要：大型发电机的转子绕组故障较为频繁,而对转子绕组的检查特别是对绕组匝间短路的检测和判断方法虽然比较多,但大都不是很准确和实用,在故障发生的初期很难判断出来。文章阐述了发电机转子故障的情况,通过各项电气试验,很好地解决了转子绕组的故障。Large generators have frequent rotor winding failures.Although there are many methods to examine rotor windings,especially for inspection and judgment of turn-to-turn short circuit in rotor windings,most of them are not accurate and practical,being hard to recognize the failures at the very beginning.This paper introduces a special failure in rotor windings of the generator,which has been solved at last through several electrical tests.
