平煤矿区输电线路防止雷击和舞动灾害的研究与实践

摘要

针对平煤矿区35 kV及以下输电线路的雷击和舞动问题,分析了矿区雷电和舞动灾害的基本活动规律,给出了具体的防雷及防舞动措施.实际应用表明,该防雷及防舞动措施可有效降低矿区输电线路事故跳闸率.%In view of problems of lighting and galloping of 35 Kv transmission line of Pingmei Mining Area, the paper analyzed basic active regularity of lighting and galloping disasters and gave concrete measures of preventing lighting and galloping. The actual application showed that the measures can reduce accident trip rate of transmission line of mining area effectively.
