摘　　要：对浙江电网2011年至2015年的高压电缆故障、缺陷和隐患情况进行了统计,介绍了故障、缺陷和隐患的主要类型,分析了主要原因及其形成机理。结果表明,电缆附件施工工艺不合格和外力破坏是引起电缆故障的最主要原因。基于高压电缆故障、缺陷和隐患分析,对目前高压电缆安装、施工及运维中存在的问题进行了总结分析,并针对性地提出了应对措施和建议,为高压电缆的安全稳定运行提供保障。High-voltage cable faults, defect and hidden trouble of Zhejiang power grid are statistically analyzed from 2011 to 2015. By introducing the main kinds of faults, defect and hidden trouble, the main cause and its mechanism of cable faults are analyzed. The conclusion is given that the unqualified cable accessory construction and external damage are the principal causes of cable faults. Based on the analysis of high-voltage cable faults, the problems of ca-ble accessory installation construction and operation are summarized. Responses and suggestions are pertinently given to guarantee the safe and steady operation of high-voltage cables.
