电力设备典型缺陷红外诊断研究

Research of Infrared Diagnosis of Electrical Equipment Typical Defects

电力设备红外诊断技术已成为电力设备状态评价工作的重要手段之一。通过对生产实际中发现的电气连接不良、导线螺旋发热和变压器油箱螺栓发热等典型设备缺陷进行分析,总结了电力设备热缺陷的典型特征,并给出了缺陷致热的内在机理。

Infrared diagnosis technology of electric equipment has become one of the important means to evaluate the state of electric equipment. In this paper, the typical equipment defects such as poor elctr ic connection, electric wire spiral heat and transformer tank bolt heating were analyzed. Based on the analysis, the typical characteristics of thermal defects were summarized. Furthermore, the inner mechanism of heating defects were analyzed.
