The invention belongs to the technical field of cable and cable accessory temperature monitoring, and provides a cable accessory temperature data abnormity judgment method, which comprises the following steps of 1, acquiring a surface temperature image and an environment temperature image of a cable accessory; 2, analyzing and processing the surface temperature image of the cable accessory and the environment temperature image to obtain a difference value between the surface temperature of the cable accessory and the environment temperature; 3, analyzing and processing the surface temperature image of the cable accessory in the set time period to obtain the rising rate of the surface temperature of the cable accessory in the set time period; 4, when the difference value between the surface temperature of the cable accessory and the environment temperature is larger than zero, and the speed of the surface temperature of the cable accessory in a set time period is larger than a threshold value, temperature alar
