一起110kV复合套管充油终端故障分析及对策

110kV Composite Bushing Oil Terminal Fault Analysis and Countermeasures

通过对一起发生故障的110kV电缆线路户外电缆终端进行解剖,分析认为造成故障的主要原因是应力锥与电缆表面界面压力不足及电缆绝缘表面处理可能存在缺陷,并提出防止该类故障的对策。

Based on the fault of 110kV cable line outdoor cable terminal were dissected,analysis the main reasons of causing faults is a stress cone and cable surface interface pressure is insufficient and cable insulation surface treatment may be put in blemish,put forward to prevent the fault countermeasures.
