摘　　要：为改善传统高压输电电缆故障分析方法的局限性,提出从高压输电电缆投入运行至故障退运的全寿命运维周期进行分析的方法,从电缆接头制作工艺、现场运行环境、运维检测数据和故障后试验检测等方面综合分析电缆故障,利用该方法对华北地区某实际电缆故障案例进行了多角度分析,追溯故障的根本原因,结果表明了此方法的有效性,可为同类型故障分析提供参考。In order to improve the limitations of the traditional high-voltage transmission cable fault analysis method,this paper proposes a method to analyze the whole life operation and maintenance cycle of high-voltage transmission cables from putting into operation to fault return,comprehensively analyzing cable faults from the aspects of cable joint manufacturing process,field operating environment,operation and maintenance detection data and post-fault test detection.This method is used to analyze a real cable fault case in North China from multiple angles.Through tracing the root cause of the fault,the results show that the method is effective and can provide reference for the analysis of the same type of fault.
