摘要

避雷器是保证电力系统安全运行的重要保护设备之一

而氧化锌避雷器（metal oxide arrester

MOA）以其优异的电气性能逐渐代替其他类型的避雷器

成为电力系统的换代保护设备。文中介绍了一起典型的MOA故障情况

对故障相MOA进行了解体

并对造成MOA故障的原因进行了总结分析;同时

结合解体和运行工况详述了该次MOA发生爆炸击穿的原因

MOA自身设备的不良受潮是导致这次事故的主要原因。最后

提出了一些反事故措施及合理化建议

确保及时掌握避雷器的运行状况

预防同类事故再次发生。

Abstract

A typical explosion accident of metal oxide arrester（MOA）was analyzed. And disassembly inspection of the faulty MOA was conducted to investigate the causes of the accident. The result indicates that the explosive breakdown accident was mainly induced by the damp in MOA. Some countermeasures and suggestions are offered to monitor the operation state of MOA in time

so as to prevent similar accidents.
