摘要
通过对一起发生故障的110kV架空电缆混合线路瓷套充油户外电缆终端进行解剖,分析推断造成故障的主要原因是电缆终端上端封盖与导体芯棒间的防水密封胶圈密封失效,引起电缆终端进水造成击穿故障。
Based on the failure of the 110kV overhead cable mixed lines porcelain sleeve oil-filled outdoor cable terminal were dissected, analyze and deduce the cause of failure is the main cause of cable terminal end cap with the conductor between the mandrel waterproof sealing rubber ring seal failure, caused by water caused by breakdown of cable terminal.
