摘　　要：安装线路避雷器是输电线路最有效的防雷方法之一,常规的避雷器安装方式未考虑实际杆塔的结构、地形以及闪络成本等问题,导致技术经济性较差,存在一定的盲目性。为研究避雷器的经济性安装方案,基于ATP-EMTP与电气几何模型建立了同塔双回杆塔电磁暂态分析模型。研究了杆塔结构、地形地貌对双回线路闪络风险的影响,并考虑线路闪络成本对避雷器安装方式的影响,提出利用技术经济性指标W对避雷器不同安装方式下的防雷效果和经济性进行综合评估,当W>0时,避雷器安装具有经济性,W值越大,技术经济性越强。Installing line arresters is one of the most effective lightning protection methods for transmission lines.Conventional arrester installation methods do not consider the actual tower structure,terrain,and flashover cost,which leads to poor technical and economic efficiency and a certain degree of blindness.In order to study the economical installation plan of the arrester,based on the ATP-EMTP and the electrical geometric model,the electromagnetic transient analysis model of the double-circuit tower on the same tower was established.The impact of tower structure,topography and landform on the flashover risk of double-circuit lines is studied,and the impact of line flashover cost on the installation of arresters is considered.And it is proposed to use the technical and economic index W to comprehensively evaluate the lightning protection effect and economy of the arrester under different installation methods.When W>0,the installation of the arrester is economical.The larger the W value,the stronger the technical economy.
