The invention discloses a substation infrared detection method and system. An infrared temperature measurement instrument collects an infrared temperature measurement image in the preset same image acquisition area by presetting the same detection parameter. The infrared temperature measurement instrument carries out collecting at a field preset standard temperature measurement coordinate point of a substation. According to the infrared temperature measurement image, whether the substation has a heating defect is detected. According to the invention, the temperature is detected at the same temperature measurement coordinate to realize fixed point detection; the infrared temperature measurement instrument generates a reference image from a standard image through a diagnostic rule setting system, so as to calibrate an image collecting area and realize the purpose of image fixing; in addition, the same detection parameter is used for repeated detection, so as to realize calibration; the infrared detection of the substation is more standard; the infrared detection workload of operation and maintenance staff is reduced; the infrared detection quality is improved; the equipment state is enhanced; and missed infrared detection is avoided.
Description
technical field [0001] The invention relates to the technical field of infrared detection of electric power technology, in particular to a substation infrared detection method and system. Background technique [0002] Infrared electrification detection is currently the main means to discover equipment current-induced heating and voltage-induced heating defects, and it is of great significance in daily maintenance of substations and equipment status control. At present, according to the relevant requirements of infrared live detection work, power substation operation and maintenance personnel should complete infrared live detection of power substation equipment every month, and conduct general inspection of equipment in the station once. If problems are found, they need to collect maps and report defects in the PMS2.0 system. It is also necessary to complete the collection, analysis and entry of the temperature measurement maps of all equipment twice a year. [0003] At pres...
