红外测温技术在架空输电线路故障诊断中的应用

Applications of Infrared Thermometry Technology in Fault Diagnosis of Overhead Transmission Line

针对架空输电线路负荷电流不断攀升的现状,提出采用红外测温技术诊断架空输电线路故障的方案,介绍红外测温技术理论依据及其注意事项,从导线的连接形式、施工质量、环境因素等方面分析影响导线温度的因素,并通过实例验证了该方法的准确性。

In view of the present situation about the rising ofload current of overhead transmission line, this article adoptsthe infrared thermometry technology in the fault diagnosis ofoverhead transmission line. The theory and matters needingattention of the infrared thermometry technology are intro-duced, and the factors affecting the conductor temperatureare analyzed from the aspects of connection mode of the con-ductors, construction quality, environment, and so on.Through several examples, the accuracy of this method isverified.
