摘要

针对泸州电厂雷雨季节期间经常发生 10 kV 架空线路跳闸现象，对架空线路跳闸率高的原因进行了分析，探讨可能的改善措施，提出了将氧化锌避雷器更换为带间隙避雷器的解决方案。理论分析和现场应用表明这一措施有效减少了感应过电压引发的线路跳闸，提高了架空线路运行可靠性。

Abstract

The 10 kV overhead lines of Luzhou power station frequently trip out due to lightning overvoltage in thunderstorm season． The reasons of high trip － out rate are analyzed and the potential solutions are discussed． Theory analysis and field application show that substituting the existing MOA with arrester with gaps can effectively reduce the trip － out rate，which can significantly improve the operational reliability of overhead lines．
