摘要
某220k V电缆线路在进行耐压试验时,加压4min发生绝缘击穿事故。为了判断事故原因,对电缆终端进行解剖试验,分析故障产生的原因,为类似电缆故障处理提供了经验。
When a 220kV cable line is withstanding voltage test, an insulation breakdown accident occurs at the curent of loading 4 minutes. In order to judge the cause of the accident, the cable terminal is dissected and the causes of the fault arc analyzed, which provides experience for similar cable fault treatment.
