发电机转子绕组不稳定接地处理办法

摘要

Hydro-generator rotor winding of yantan power generation company in unstable ground preventive test of introduction, analyzes the reasons of rotor grounding and judgment,this paper introduces the use of megger constant high pressure test volt-age applied combined with external force and the change of surface temperature insulation malfunction point method theory,can be used for reference in the similar situation%对岩滩发电公司水轮发电机转子绕组预防性试验中出现不稳定接地的情况进行介绍,对转子接地的原因进行了分析与判断,介绍了使用兆欧表施加恒定高压试验电压结合外力作用及改变绝缘表面温度查找故障点的方法理论,可供类似情况参考.
