摘　　要：对金属氧化物避雷器状态评价的过程方法进行了详细阐述,对花220 kV南母东金属氧化物避雷器评价结果的应用进行了深入的分析,指出:影响避雷器评价结论的关键因素是密封性、外绝缘防污水平、外套与法兰结合情况、在线监测泄漏电流表状态及指示情况、电气试验等权重比较大的状态量。避雷器评价最常见的问题是:设备基础资料完整性较差,生产管理系统设备信息不全面,格式不统一,信息变更录入及时率低等。The method and procedure of the condition evaluation about the metal oxide arrester are expounded in detail, and analyzes the application of the evaluation results of 220 kV Nanmudong metal oxide arrester is analyzed deeply, the key factors that influence MOA evaluation result are the eriterias which has large weight, such as the leak tightness, external insulation level, the combine condition of sheath and flange, On-line monitoring leakage current meter status and instructions, electrical test, etc. The most common problem of arrester evaluation are： the poor integrity of equipment foundation data, the uncomprehensive equipment information of production management system, non-uniform format, low timeliness rate of input for Information changes, etc.
