Based on infrared temperature measurement technology,a new intelligent perception method of thermal state of intelligent substation equipment was proposed.Combined with the Tophat transformation method,the bright-ness of the infrared temperature measurement image was equalized,and the effective separation of the thermal state area and the background area was realized by judging the signal-to-noise ratio.The third-order color moments were defined and fused to obtain the color features of the infrared temperature measurement image.By constructing gray-scale criteria for images,the operational status of substation equipment was clarified.The perception effect of this method was tested,and the results showed that the method had a high sensitivity to the perception of the thermal state of the equipment.
