带电检测在金属氧化物避雷器状态检修中的应用

摘要

探讨了MOA带电检测的有效性和重要性，论述红外热像检测和阻性电流检测两种技术的特点和适用范围。利用这两种带电检测技术，发现一起110 kV主变中压侧避雷器的受潮缺陷，成功避免了避雷器接地故障和主变短路冲击事故的发生。%This article discusses the effectiveness and importance of MOA electrified test, and summaries the characteristics and scope of application of infrared thermography test and resistive current test technology. Through with these two live detection technologies, an arrester damp defect on the medium voltage side of a 110 kV transformer was found, a ground fault of the arrester and a short-circuit impact accident of the transformer were successfully avoided.
