摘要
介绍了某220 k V电流互感器在运行中出现油色谱异常情况,分析了该电流互感器的局部放电试验、介质损耗试验及绝缘油试验数据,结合解体检查情况找出故障原因,并提出相应的防范措施。
This paper introduces oil chromatogram anomalies condition in given 220 k V current transformer. Through the analysis of partial discharge test data,dielectric loss test and insulating oil test data,combining disintegration inspection to find out the fault cause,the corresponding preventive measures are put forward.
