摘　　要：阐述了避雷器的污秽性能及长期气候特性,分析了避雷器有关标准要求和5000h气候老化试验。结果表明:在持续施加工作电压、阳光辐射、人工雨、加热、潮湿和盐雾等综合效应的作用下,憎水性、迁延性及耐漏电起痕特性均有较好的表现;建议在典型的自然环境条件下,建立户外自然污秽试验场,以研究带电情况下避雷器的长期特性。The anti-pollution and anti-weathering performance of MOA was described and the requirements for MOA stipulated in relevant standards and 5 000 h weathering test results were analyzed. The result shows that the MOA performs well in respects of hydrophobility, migration and tracking re- sistance under synthetic subjection of continious operating voltage, solar radiation, artificial rain, heat- ing, moisturizing and salt fog. It is suggested to built an outdoor natural pollution test site under typical natural environment conditions for verification of the long life performance of MOA.
