一种改进的劣化盘形悬式瓷绝缘子红外热像诊断方法

A Improved Method of Detecting Deterioration Insulator Based on Infrared Thermal Image

在对盘形悬式瓷绝缘子的发热机理进行研究分析的基础上,结合绝缘子串的红外热像实验室模拟试验及现场实测,提出了一种改进的基于红外热像原理的劣化绝缘子诊断方法。现场检测结果显示,该方法能够有效提高基于红外热像原理的劣化绝缘子检测的正确率。

An improved method of deterioration insulator diagnosis is proposed in detail based on the study of heating mechanism of ceramic cap and pin insulator and the experimental data from both laboratory simulation test and on-site test on insulator strings by infrared thermal image method. Onsite test results show that the method can effectively improve the detection accuracy of deterioration insulator on the basis of the principle of infrared thermal image.
