由转子接地故障引发的水轮发电机转子磁极引线方式探讨

Discussion of Pole-lead Arrangement of Hydrogenerator Caused by Rotor Grounding Fault

以某抽水蓄能电站发生的一起由转子接地故障引发的典型转子磁极引线故障为研究对象,介绍了故障发生及故障点确认过程,并分析了水轮发电机转子磁极引线发生故障的原因,最后从设计和维护角度提出了防止转子磁极引线故障的改进措施。

With a typical pole-lead fault caused by rotor grounding alarm in a pump storage power station, the process of fault occurrence and determination of fault point were introduced in detail. The reason for the fault of pole-lead was analyzed. In addition, improvement measurements for preventing the pole-lead fault were proposed in the aspect of generator design and equipment maintenance.
