| 摘 要： | 为求解装有避雷器的220kV输电线路反击耐雷水平，基于杆塔的多波阻抗模型，根据求解分布参数线路波过程的Bergeron特征线法和求解开关电路的补偿法，建立了装有避雷器的输电线路防雷计算模型，比较了雷直击杆塔时安装不同支数避雷器的防雷效果，探讨了接地电阻、线路档距等对线路型避雷器使用效果的影响。

| Abstract: | To solve the back striking ers, based on multi-wave impedance lighting withstand level of 220 kV transmission lines equipped with arrestmodel, according to the method of Bergeron traveling wave and switching circuit compensation, a computational model of transmission line with arresters installed is constructed in this paper. The impact of some factors such as a number of arresters, ground resistance of tower and span of line, on lightning with stand level were analyzed. |
