摘要
薛家湾地区属于丘陵地带,沟壑纵横,环境恶劣,每年的平均雷暴率较高,属于多雷地区,该地区输电线路近年来频繁发生雷击跳闸故障,严重危害了输电线路的安全、稳定运行,给该地区的电网造成了严重危害。本文针对准格尔地区输电线因雷击而造成的高跳闸率进行研究与分析,找出符合准格尔地区实际应用的防雷整改措施,从而有效地降低该地区的雷击跳闸率。
Xue jia wan area is located in hilly land, gully aspect and the environment is bad, the annual average thunderstorms rate is higher, which belongs to many mine areas, The transmission line in this area occurs lightning trip-out failure frequently in recent years, which harms to the safety and stable operation of the transmission line seriously, for the region＇s power grid caused serious harm. This paper researches and analyzes the high trip rate of ZhunGeEr area transmission line, it is resulted by lightning strike, and find out rectification measures about avoiding lightning strike so as to effectively reduce the region＇s lightning trip-out rate ang this measures accord with the actual application of ZhunGeEr region.
