摘　　要：针对500kV输电线路盘式绝缘子串所用招弧角保护失效的问题,进行了招弧角与绝缘子串不同配合比下的雷电冲击放电试验,根据招弧角对绝缘子串的保护效果,得出推荐配合比。对推荐配合比下的绝缘子串和招弧角开展操作冲击试验,验证了推荐配合比下装设招弧角的绝缘子串绝缘强度满足系统运行要求。Ai ming at the protection failure of parallel gap device on disc insulator insulators of 500 kV transmission lines,lightning impulse tests are carried out under different ratios of parallel gap and insulator string.According to the protection effect of parallel gap,the recommended ratio is obtained.Switching impulse test is carried out under the recommended ratio of parallel gap and insulator string,in order to verify the recommended ratio design can meet the demand of system operation.
