The invention discloses a power equipment wireless infrared temperature measurement temperature correction method in the field of relay protection, for correcting the temperature, measured by a wireless infrared temperature measurement apparatus, of power equipment. The method comprises the following steps: obtaining a curve of change of the temperature of the equipment along with time on the day last year, a curve of change of an ambient temperature along with time on the day last year and a curve of change of the current of the equipment along with the time on the day last layer, which are measured by the wireless infrared temperature measurement apparatus, and calculating a historical current temperature rise value; obtaining the current of the equipment on the day, the ambient temperature of the day, and the temperature of the equipment on the day, which is measured by the wireless infrared temperature measurement apparatus; calculating a current temperature rise value of the day; and obtaining a temperature correction value, and finally obtaining the real-time temperature of the equipment after correction. The method provided by the invention has the technical advantages of being simple to realize and improving the correction accuracy.
