摘　　要：针对甘肃某供电局输电线路氧化锌避雷器(Line MOA)应用现状,对Line MOA结构进行分析。筛选了两只运行两年多,动作次数较多的220 kV线路氧化锌避雷器,通过试验分析,得出,选型时应优先选用复合外套和耐污型瓷外套氧化锌避雷器;应选用"免维护"型线路避雷器。Aiming at MOA application status of a power supply bureau transmission line in Gansu, the structure of line MOA has been analyzed in this paper. It screen out two 220 kV MOA of running over two years and having more action number, this study summarize the attentive question of model choice,h point out that it is necessary to firstly choose polymer and porcelain housings MOA and generalize maintenance-free MOA.
