摘　　要：针对某风电场35kV风机集电线路电缆中间接头接地故障,引发35kV母线PT柜内相间短路,结合现场实际情况和故障录波波形全面分析接地故障产生的原因,认为是典型的接地故障。可以确认故障性质和范围,为查找故障点提供依据。对照防范措施要求,防止类似不安全事件重复发生并提出相应的处理办法及改进措施。In view of the grounding fault of the middle joint of the cable of the 35kV fan collecting line in a wind farm, the phase to phase short circuit in the PT cabinet of the 35kV bus bar is caused. Combined with the actual situation on the spot and the fault wave recording waveform, the causes of the grounding fault are comprehensively analyzed, and it is considered to be a typical grounding fault. It can confirm the nature and scope of the fault, and provide the basis for finding the fault point. According to the requirements of preventive measures, I need to prevent the recmTence of similar unsafe events and hereby put forward the corresponding treatment and improvement measures.
