高压瓷质绝缘子红外检测盲区分析
Analysis of High-voltage Ceramic Insulators Infrared Detection Blind Areas
摘要
Abstract
In order to solve false negative problems of the insulator detection,we propose a method to compute the blind areas of the infrared detection by using the Thevenin equivalent circuit method.In the process of quantitatively analyzing the disc suspension insulator voltage distribution,we take the infrared detection blind areas range into consideration.The results show that voltage distribution and temperature range are two core influential factors of the infrared blind areas detection,at the same time,the variation curves between the two factors and the blind areas are also found.On the basis of blind areas variation detection data,we propose some methods to narrow blind areas such as segmenting insulator strings while detecting and choosing different temperature ranges and so on.Finding the range of blind areas will facilitate the application of infrared detection technology.Narrowing the blind areas will be of great guiding significance to the discovery of severe deterioration of the insulator and the improvement in the accuracy of infrared detection and reduction of the grid failure.关键词
