摘　　要：为了研究不同避雷器配置方案的防雷效果,有选择地加装线路避雷器来减少雷电引起的绝缘闪络。本文利用ATP软件建立了先导闪络判据模块,选取了典型的220k V同塔双回和220/110 k V同塔混架四回杆塔结构,研究不同避雷器配置方案下的线路单回及多回闪络耐雷水平,为同塔多回输电线路的前期设计和后期运维改造提供参考和依据。In order to study the effects of different arrester installation configuration on the lightning protection and to reduce the insulation lightning flashover probability by a selective installation of transmission line surge arresters, ATP simulation software is used to establish the leader flashover judgment criteria model. The typical 220kV double circuits and the mixed four circuit with both 220kV and 110kV are chosen to study the line withstand lightning levels of the single circuit or multi-circuits under the different surge arrester installations. The results can be as reference to the earlier stage design or later stage maintenance of the multi-circuits transmission lines.
