对运行中的金属氧化物避雷器进行红外检测是重要的缺陷诊断手段,通过一起10k V避雷器发热故障的发现与确诊,认为避雷器缺陷原因为受潮,结论证明红外检测技术在避雷器缺陷检测方面有较高的准确度。
Infrared detection of running metal oxide surge arresters is an important method of fault diagnosis. Through the discovery and diagnosis of a 10kV arrester heating failure, it is considered that the reason of arrester defects is damp. The conclusion shows that the infrared detection technology has a higher detection limit in arrester defects Accuracy
