【Abstract】 The heating of transformer bushing has a negative effect on the safe operation of transformer. Therefore, it is very important to detect and judge the heating fault of transformer bushing accurately. The causes of the transformer bushing heating are introduced. Based on a heating fault of high voltage bushing happened in a 110 kV substation, the infrared detection process is introduced. The cause of the heating is analyzed accordingly. Corresponding treatment is proposed. By summarizing the experience obtained from the analysis of infrared thermal image and oil chromatographic data of transformer high-voltage bushing, the method for judging heating defect of entire transformer high-voltage bushing is proposed. Specific suggestions are made for the analysis and treatment of such problems, so as to improve the detection and treatment efficiency of transformer high-voltage bushing defects.更多还原
