Dianci bileiqi, 2013 500 kV线路雷击事故是引起线路跳闸的主要原因,对于复杂地形下的线路尤其如此。本文采用ATP-EMTP和电气几何模型对典型500 kV线路受地形因素影响下的绕击耐雷水平进行了分析,对线路避雷器在防雷中的工作原理进行了解释,对500 kV普洪一线的雷害治理情况进行了说明。研究表明,在线路防雷过程中,应该更加重视地形地貌的影响,对于复杂地形多雷区线路使用线路避雷器进行雷害治理是有效手段。

Dianci bileiqi架空配电线路分布广泛且线路绝缘水平低，易发生直击雷和感应雷闪络故障，为了考虑配电线路受直击雷和感应雷过电压的综合影响，建立了配电线路耐雷性能计算模型。首先基于ATP-EMTP建立线路直击雷和感应雷过电压模型对线路耐雷水平进行仿真计算，然后通过电气几何模型并结合线路感应雷耐雷水平关于雷击点至线路距离的拟合关系式，对线路直击雷和感应雷闪络区域进行划分，进而计算得到线路直击雷和感应雷跳闸率，最后，计算分析了杆塔高度和大地电导率对配电线路耐雷水平以及雷击跳闸率的影响规律。计算结果表明 ...
