远红外线技术在氧化锌避雷器故障检测中的应用

The application of infrared ray technique for failure checking in arrestrs

利用远红外热成像仪 ,对氧化锌避雷器进行绝缘故障带电检测的试验 ,测试结果表明 ,当检测到某相氧化锌避雷器各节间温差大于 1℃时 ,则表明该相氧化锌避雷器 (MOA)发生了绝缘劣化 ,应进行停电检测。

This paper introduces a testing method using infrared hot imaging instrument to check insulated failure of MOA on-line.When temperature differences beyond 1℃ between each section of the MOA,the result indicates insulation defect.It should be checked the MOA off-line.
