摘　　要：架设耦合地线是一种有效降低线路反击跳闸率的防雷措施。本文选取了典型的220 kV同塔双回线路杆塔结构,利用ATP软件建立了输电线路建立了输电线路Jmarti模型和绝缘子先导闪络判据模块,研究不同杆塔接地电阻下耦合地线的不同配置方案时同塔双回输电线路单回及双回闪络耐雷水平,为同塔双回输电线路的前期设计和后期运维改造提供参考和依据。Mounting coupling ground wire is an effective lighting protection measure to reduce trip- out rate of back flashover. In order to study the effect of lightning protection, reduce the occurrence probability of insulation flashover caused by ng, ATP simulation software is used to establish the transmission line Jmarti model and insulator string flashover mode. Typical tower structure of the 220 kV double circuit transmission line is chosen to research the single back flashover and double-loop simultaneous flashover withstanding level under different reference and basis for preliminary design and coupling ground wire mounting options. This provides late reformation of double circuit transmission line.
