[Abstract]:This paper introduces the basic principle of infrared detection of electrical equipment, the method of infrared diagnosis, the factors affecting the accuracy of diagnosis and the countermeasures. Based on the infrared diagnostic technology, the infrared thermal image of the defects of each electrical equipment is given and analyzed and judged. The advantages and disadvantages of infrared detection technology in practical application are analyzed by taking the infrared image of electrical equipment in Jiangyin power grid as an example. The full text is divided into five chapters: the first chapter describes the research background and significance of the topic. The present situation of development at home and abroad is briefly introduced. The second chapter introduces the basic theory of infrared detection technology, the causes and types of heating failure of electrical equipment, briefly describes the basic principle of infrared detection of electrical equipment and the basic instruments used in infrared detection. Using the infrared detection technology to judge the fault condition of the equipment, it is necessary to diagnose according to the type that causes the equipment to heat up and combine with the equipment itself and the operation condition, and to take into account the situation that may cause the wrong judgment. The third chapter summarizes the methods and judgment basis of infrared diagnosis technology, and the factors affecting infrared diagnosis, puts forward the methods and precautions to reduce the errors, and improves the accuracy of infrared diagnosis of electrical equipment defects to the maximum extent. In the fourth chapter, the structure characteristics of electrical equipment are briefly introduced, and the infrared thermal image of each equipment is analyzed briefly according to the typical spectrum obtained by infrared detection of electrical equipment in Jiangyin power network. By giving three examples of defects found in infrared detection and technical improvement of one testing method, the formation, causes and treatment measures of defects are analyzed in detail. It is shown that infrared detection technology plays a very important role in condition based maintenance. With the development of technology, infrared detection technology is becoming more and more diversified. In the fifth chapter, the work of this paper is summarized, and the further work and research direction are prospected.
