220kV电流互感器带电检测数据异常分析及处理

Analysis and Disposal of On-line Detection Data of 220kV Current Transformer

通过对出现介损偏大的220 kV电流互感器进行介损电容量带电检测、带电油色谱检测、停电试验及解体检查,分析出缺陷原因,并提出预防措施。

Through on-line detection of dielectric loss and capacitance,on-line chromatographic detection,off-line testing and disassembly of a 220 kV current transformer,whose dielectric loss is abnormal,the defects cause was analyzed and corresponding preventive measure was proposed.
