以二滩水电站为例,介绍了大型水轮发电机组接地故障的类型及危害,对发电机转子一点接地故障进行了分析,提出了发电机组发生转子一点接地故障时的查找及处理方法,指出二滩电站发电机组转子一点接地属于动态不稳定接地,很难查明故障原因。
以二灘水電站為例,介紹瞭大型水輪髮電機組接地故障的類型及危害,對髮電機轉子一點接地故障進行瞭分析,提齣瞭髮電機組髮生轉子一點接地故障時的查找及處理方法,指齣二灘電站髮電機組轉子一點接地屬于動態不穩定接地,很難查明故障原因。

Taking Ertan hydropower station as an example , the patterns and consequences of grounding faults occurred in large-scale water turbine generator sets are discussed .The one point grounding fault of generator rotor is specifically analyzed .Searching and treatment measures for this kind of fault are proposed .It is found that the one point grounding faults of generator rotor occurred in Ertan hydropower station are dynamic unstable grounding , therefore the causes are difficult to identified .
