摘要
结合辽宁电力有限公司某变电站油浸式电流互感器局部放电的故障实例,对该设备结构、故障情况、试验数据和解体检查等方面进行阐述和分析,得出导致此次局部放电的原因是绝缘受潮的结论。最后,对电流互感器的制造工艺和检测方法提出了具体建议。
This paper elaborates and analysis device structures,fault conditions,experimental data and strip inspection combining with partial discharge failure of the oil-immersed current transformer in a substation in Liaoning Electric Power Co., LTD., and drews the conclusion that the internal damp leads partial discharge. Finally, some suggestions of current transformer manufacturing process and testing methods are put forward.
