| 摘 要： | 应用ATP-EMTP对配网架空线路雷电感应过电压下,线路避雷器的保护效果进行了仿真计算研究。仿真计算结果表明,安装线路避雷器可以对配网架空线路雷电感应过电压进行防护,其保护效果与避雷器的配置方式及线路杆塔接地电阻有关,降低杆塔接地电阻可以减小线路避雷器的安装密度。

| Abstract: | Using the electromagnetic transient program ATP-EMTP,a simulation study of the lightning-induced overvoltage protection by line surge arresters in the overhead transmission line is presented.The simulation results show that the overhead transmission line can be protected from the lightning-induced overvoltage by the installation of line surge arresters.The configuration of surge arresters and grounding resistance of transmission line can have influence on the lightning protection effects,thus the density of line arrester installation can be reduced by lowering tower grounding resistance. |
