摘要
为保证金属氧化物避雷器(MOA)的安全运行,必须测试避雷器的电气性能。目前,检测避雷器的方法主要有周期性停电预试、带电测试和在线监测等。重点介绍了周期性停电预试和带电测试的应用情况,并对其进行了比较。认为带电测试时,当IRIP/IX<20%,可判断避雷器是正常运行的。对于MOA的维护,可以带电测试为主,停电预试为辅相结合的方式,效果较好。
In order to ensure reliable service of metal-oxide surge arresters （MOA） , the electrical properties of MOA must be monitored. Now there are some methods of MOA testing such as regularly de-energized testing, energized testing and on-line monitoring. According to practice of our bureau, the practical application of regularly de-energized testing and energized testing are presented, and the testing results of those are compared. It is considered that the MOA is deemed normal when IRIP/IX〈20% at energized testing. And the energized testing combined with the de-energized testing at the MOA maintenance is satisfactory.
