水轮发电机转子动态接地故障原因分析及处理

Analysis and Treatment for Dynamic Grounding Fault of Hydrogenerator Rotor

针对水轮发电机转子动态接地故障的特点,从制造、检修安装、运行等方面进行了分析,通过对保护装置、外围设备、磁极等进行反复检查、试验,提出建设性的空转测量方法,找出故障点,彻底处理故障,这种特殊的转子接地故障处理经验具有现实指导意义。

In view of hydrogenerator rotor dynamic grounding fault characteristics, analysis is carded out from aspects of manufacture, overhaul installment, operation and so on. Through repeated examinations and tests, constructive proposals for the measurement of no-load operation is given, to find out the fault location and eliminate the fault thoroughly. This special experience of rotor ground fault treatment is of great practical significance.
