摘要
某水电厂新投运的220 kV交联电缆运行中突然发生故障,电缆导体对屏蔽形成贯穿性故障。为分析寻找引发故障原因,对电缆进行解剖试验分析,认为电缆可能存在外半导层贯穿性损伤,并对结果进行了验证试验和有限元电场模拟计算分析,结果与结论相吻合。
A new 220 kV XLPE cable was burst with fault in server at a hydraulic power station, and results that the cable conductor flashes to shield. The cable was dissected and tested, The cause of fault was that the cable out shield with transfixion damage, the results of test research accorded with calculation of finite element.
