摘要
对一起10kV交联聚乙烯电缆缺陷分析,采用振荡波试验进行缺陷原因分析并成功发现电缆金属外金属屏蔽层熔断的故障,避免了振荡波检测中误判造成的误切电缆,并根据缺陷分析结果提出了相应的解决办法和巩固措施。
For the analysis of 10 k V XLPE cable defects,the oscillating wave test was used to analyze the cause of the defect and the fault of the metal shield of the cable metal was successfully found.The miscut cable caused by misjudgment in the oscillating wave detection was avoided and analyzed according to the defect.The results propose corresponding solutions and consolidation measures.
