高压电缆故障分析及检测方法研究

Research on Fault Analysis and Testing Methods of High Voltage Cable

分析了高压电缆故障产生原因,包括生产制造过程、安装调试过程、绝缘老化原因、外力破坏原因。在此基础上对电力电缆故障进行分类,并详细介绍了电缆故障的检测方法,对电缆运行维护工作具有积极作用。最后,给出四点高压电力电缆故障预防措施,对减小故障发生率具有重要意义。

This paper analyzed the causes of the fault of high voltage cable, including the manufacturing process, installation and debugging, insulation aging and external force on the basis of which the classification of fault of power cable was made, and dete- ction methods of cable fault were introduced. All this has exerted a positive effect on the operation and maintenance of power cable. Finally, the paper pointed out four measures for preventing the faults of high-voltage power cable, which is of great significance to the reduction in the occurrence rate of faults.
