摘　　要：为分析线路避雷器对1 000 kV交流输电线路耐雷水平的影响,用ATP-EMTP软件建立相应的元件仿真模型,并就避雷器安装方式、工频电压和接地电阻对反击与绕击耐雷水平的影响进行仿真分析,分析结果表明:线路避雷器可显著提高1 000 kV交流输电线路的耐雷水平,减少雷击跳闸事故。To analyze the impact of line arrester on lightning withstand level for 1 000 kV AC transmission line, the corresponding component models are created by ATP-EMTP, and the effect of line arrester installation mode, the frequency voltage and the grounding resistance on back striking and shielding failure lightning withstand level are simulated and analyzed. The results show that： line arrester can significantly increase lightning withstand level for 1 000 kV AC transmission line and reduce lightning trip-out accidents.
