Research on Fault Diagnosis Method of Sliding Ring Box Based on High Temperature Area Detection
During the operation of the slip ring box,the friction between the slip ring and the carbon brushes will easily lead to the wear and tear of the carbon brushes,which will affect the normal operation of the slip ring box,and thus cause electrical accidents.The working mechanism and common infrared diagnostic methods of the slip ring box are introduced,and the feasibility of the high temperature area detection algorithm is discussed.Using infrared temperature data,a slip ring box fault diagnosis algorithm based on high temperature area detection is proposed,which realizes the timely discovery of slip ring box faults and arranges for overhauling by detecting high temperature zones inside the area and using the average temperature rise of high temperature areas as well as the average temperature difference of adjacent high temperature zones to carry out fault diagnosis.After on-site verification,the program can effectively identify slipring box faults with hightemperature phenomena.
