关于110kV线路避雷器故障的分析与探讨

在架空输电线路的运行过程中,有时会因为种种原因将部分线路改建为地下电缆。为解决电缆线路的防雷问题,需在电缆两终端安装线路避雷器,保护高压电缆和电缆头不受到线路过电压的损害。本文从110KV泸柏线线路避雷器爆炸断裂、终端连接导线被灼断这一事故,就110KV线路避雷器故障进行分析和探讨,并提出了防范类似故障的一些设想。

Analysis and Discussion on Fault of the 110kV Line Lightning Arrester

In the operation of overhead transmission lines, sometimes it may change some of the lines into underground cables for various reasons. To address the issue of lightning protection of cable lines, the arrester need installing in the two terminals of the cable line to prevent the high-voltage cables and cable head from the line over-voltage. This paper analyzed and discussed the fault of 1 IOKV line lightning arrester from the accident of the explosion of 1 IOKV Lu-Bai line arrester and the terminal connecting wire burning off, and put forward some suggestions to prevent similar failures.
