摘要
针对500kV包丰线和丰徐2号线频繁发生雷击跳闸的问题,围绕线路耐雷水平从自然条件、气象条件、塔头间隙、绝缘子串长、防雷与接地等方面进行了对比分析,找出了频繁发生雷击跳闸的原因,并提出了改进方法。
Comparison Analysis is made in aspects concerning lightning withstanding level of transmission line such as natural conditions, weather conditions, tower top gap, insulator string length, protection against lighting and lightning stroke tripping, The causes of frequent lightning stroke tripping are founded and improvement is proposed.
