摘　　要：开展输电线路耐雷水平影响因素的研究是科学的输电线路防雷设计的基础。由于我国规程规定,35 k V的配电网是不需要全线架设避雷线的,这对农网35 k V配网的线路防雷工作带来了非常大的困难。选择雷击事故较为严重的35 k V某线作为研究对象,结合该线路的具体参数,利用电力系统电磁暂态计算程序(ATP-EMTP)进行仿真计算。利用所建立的仿真模型,针对接地电阻、绝缘子片数、有无避雷线、杆塔呼称高度、线路档距等因素进行了仿真,分析了其对35 k V输电线路耐雷水平的影响。同时,分析研究了加装线路型避雷器以及避雷器多种不同布置方式下,对输电线路绕击和反击线路耐雷水平的影响,为工程实际中35 k V线路的综合性防雷提供理论依据。The study on the influence factors of foundation of science of the lightning protection stipulates that the 35 kV distribution network is not lightning withstand level of transmission line is the design of transmission line. National regulations required to set up lightning lines across the board, which on the 35 rural kV network distribution line lightning protection work has brought great difficulties. In this paper, a 35 kV line with severe lightning accident is chosen as the object of study. According to the specific parameters of the circuit, the electromagnetic transient program （ATP-EMTP） simulation, analyzes its influence on the lightning withstand level of 35 kV Transmission lines. At the same time, the analysis of installation of line surge arrester and lightning arrester various different arrangement under, on transmission line shielding failure and counter the effects of the lightning withstand level of the line, so as to provide a theoretical basis for the comprehensive lightning protection of 35 kV line engineering.
