摘要
该文以减少线路雷击跳闸次数、缩短停电时间为目的,通过对架空输电线路雷害过程的简要分析,结合矿区电网特点和供电要求,总结了防雷电过电压、防绝缘击穿的架空线路防雷双重保护思想。
By analyzing lightning of overhead transmission line and the power grid in mining area, This article have dual protection method to reduce the number of lightning trip and shorten the Blackout time： one is preventing lightning over- voltage , one is preventing insulation breakdown.
