摘　　要：电力电缆是城市配电网的重要组成部分,是保证电力可靠供应的重要桥梁。电缆终端是电力电缆体系中最薄弱的环节,一旦发生故障就将影响正常供电,并有进一步扩大事故的风险。介绍了热缩型高压电缆终端结构,分析电场分布及故障原因。结合热缩型高压电缆终端绝缘故障典型案例,探讨终端故障原因,提出检修与防范措施建议。Power cables are of great importance to urban distribution networks and reliable electric supply.Cable terminals are the weakest part in cable system,and will affect normal supply and may cause further accidents when encountering faults.This essay focuses on the heat-shrinkable high-voltage cable terminals,outlines their structural features,and analyzes the electric field distribution and the main fault causes.It also conceives preliminarily fault countermeasures from the perspectives of both maintenance and prevention through a typical case of insulation failure fault.
