摘要
针对一起由于水轮发电机定子端部铁心松动致使硅钢片沿径向移动,引起定子线棒绝缘破坏,引发的定子接地故障,详细分析了故障产生的原因及发生过程,介绍了故障处理方法,并提出了预防类似故障的建议。
This paper introduces a generator stator ground fault caused by stator bar insulation damage that is resulted from the stator end winding looseness and radial movement of silicon steel sheet. The paper analyzes the reason and process of fault in detail. The fault treatment method is introduced and prevention suggestion is put forward.
