摘要
介绍了3种目前常用的运行中金属氧化物避雷器(MOA)故障诊断的方法,即预防性试验、监测或检测、红外热成像,并分析了环境条件对测量结果的影响。每种方法都有其优缺点,因此在进行MOA故障诊断时应综合运用,并结合长期测试经验对测量结果进行纵向和横向比较,以便作出正确的判断,提高MOA的运行可靠性。
The 3 kinds of fault diagnosis method （preventive testing, inspection or detection and infrared photography） for metal oxide atrester （MOA） in operation were introduced, and the influence of ambient conditionson measuring results was analyzed. Each kind of method has its advantages and shortcomings.It should be synthesized to utilize and combine the test experiences for a long period, and compare with measuring results longitudinally and laterally when carrying out MOA fault diagnosis,in order to make correct judgment and improve operation reliability of MOA.
