基于阻性电流检测与红外热像技术的避雷器故障诊断

Arrester Fault Diagnosis Based on Resistive Current Detection and Infrared Thermal Imaging Technology

综合多种带电检测技术对避雷器(MOA)故障进行诊断,能有效的发现避雷器缺陷。案列说明当发现避雷器阻性电流异常时,应结合红外热像技术进行诊断,停电诊断试验说明了综合阻性电流测量与红外热像对避雷器状态检测准确判断的重要性。

The arrester（MOA） fault diagnosis based on the integrated multi-charged detection technologies, can effectively find arresters defects. Case column explains when the abnormal of MOA leakage current is found, the diagnosis should be carried out combined with infrared thermal imaging technology, power cut diagnostic test illustrates the importance of an integrated resistive current measurements and infrared thermal imaging on accurate judgments of detecting the state of the arrester.
