摘要
针对2011年山西电网110 kV及以上输电线路雷击跳闸故障,从地形地貌、保护角、接地电阻等方面分析了故障产生的原因,剖析了防雷工作中存在的问题,并从规划设计、建设施工、生产运维方面提出了相应的防范措施。
In view of the frequent lightning trip-out on 110 kV and above transmission lines in Shanxi power grid in 2011,the causes of the faults are analysed from the aspects as topography,protection angle and grounding resistance.This paper analysed the problems existing in the lightning protection,and precaution measures are proposed accordingly from the aspects of designing,construction and operation.
