摘要
发电机是水力发电厂的主要设备之一,消除接地的难点在于接地点的查找。介绍几种较为简便、快速查找发电机转子一点接地故障点的方法,分析了这几种方法的优缺点和适用范围,这些方法已经通过实例验证,可为转子一点接地故障的查找提供参考。
Generator is one of the main equipment in hydropower plants .When a one point grounding fault occurs in the generator rotor , it should be detected and eliminated timely .However , detection of the grounding point is rather diffi-cult .Several simple and quick detection methods of the grounding point are presented , which have been verified by en-gineering practice .Also, the advantages and disadvantages , as well as the application conditions are discussed .It could be a useful reference for the detection of one point grounding fault in hydro-turbine generator rotor .
