摘要
介绍一起由于局部放电引起的电容型电流互感器介损值增大的绝缘故障,对故障设备进行带电测试、油化试验、高压介损试验、局部放电试验和解体检查,分析故障产生原因,并提出预防措施,对类似情况的检查和预防具有一定借鉴意义。
A capacitive current transformer abnormal dielectric loss fault caused by partial discharge was introduced. Through the live detection, oil chromatography test, high voltage dielectric loss test, partial discharge test and disassemble inspection of the failure equipment, causes of the fault were＇ analyzed and treatment measures were proposed. Analysis results and improvement measures have reference significance for inspection and prevention of the similar situation.
