中文摘要:
      通过对两个220kV故障中间接头和一个运行中完好的中间接头进行解剖分析,判断电缆中间接头故障原因是整体预制绝缘件中内半导电屏蔽管与硅橡绝缘界面发生局部放电从而引发电树,最终形成贯穿性通道造成中间接头击穿故障。
英文摘要:
      Through the analysis of two fault 220 kV cablejoint and a good operated cable joint,it came to the conclusion that the failure of the cable joints wasthat partial discharge occuredat the conductor shielded and silicon rubber insulation interface in overall prefabricated insulation,then the partial discharge caused electrical tree and ultimately thepenetrating conducting pathway andthe breakdown failure of thejoints
