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 ...

Dianci bileiqi, 1992 采用60m长的138kV电力电缆产生的几十万伏、2万安以上的电流、波头时间约50ns的脉冲。被试品为9kV金属氧化物及碳化硅避雷器。避雷器的电压响应包括陡的过冲电压在20kA下达80kV,然后回降至残压水平。过冲系由避雷器回路内的感抗所致。ZnO 及SiC避雷器二者相近似。而残压则ZnO低,即表示其保护性能较好。用一根铝管取代避雷器接入测试回路,其感性响应过冲即消除,这可证明避雷器的响应是很快的 ...
