摘要
从线路温度过高引发断线、绝缘故障、单相接地故障、过电流保护缺陷性故障、接地系统故障等方面对10 kV电力电缆运行过程中的常见故障进行了分析,并提出有效对策,包括电力电缆绝缘性能定期检测、对运行负荷和温度进行检测、做好清洁和防雷、做好短路和断路的维护处理。
The common faults during 10 kV power cable operation were analyzed from the aspects of circuit break caused by circuit overtemperature,insulation fault,single-phase ground fault,over-current protection defect fault and grounding system failure.Meantime,the effective solutions were proposed including insulation property regular test of power cable,operation load and temperature test,cleaning and lightning protection,maintenance on short circuit and open circuit.
