摘　　要：针对500 kV油浸式电流互感器批次缺陷展开调查,通过诊断试验和解体分析综合研判该电流互感器缺陷的主要原因为器身与储油柜之间的挤压、摩擦造成局部皱纹纸损伤,在高频过电压下,局部皱纹纸发生击穿产生乙炔。最后提出相应的建议措施,为同类型电流互感器的故障诊断和运行维护提供参考。In this paper,the batch defects of a 500 kV oil immersed current transformer were investigated.Through the diagnosis test and disassembly analysis,the main reasons for the defects of this type of current transformer are found to be the local wrinkled paper damage caused by the extrusion and friction between the body and the oil conservator.Under the high frequency overvoltage,the local wrinkled paper breaks down to produce acetylene.Finally,the corresponding suggestions and measures are put forward to provide reference for fault diagnosis and operation maintenance of the same type of current transformer.
