摘　　要：本文分析了大型汽轮发电机转子在生产过程中,产生匝间短路的原因。并着重探讨了转子剩磁和转子槽楔导磁率对转子匝间短路检测的影响,具体来说就是通过探测线圈用动态波形法检测匝间短路时,这些因素会将一个没有匝间短路的转子,非正常地检测到有匝间短路故障。This paper analysis the cause of inter-turn short circuit phenomenon of large turbo generator during the manufacturing phase in manufactory, as well as discusses the influence of rotor residual magnetism and coil wedge magnetic conductivity to inter-turn short circuit, while the dynamic wave pattern method is introduced to check it.
