In order to realize the detection of surface discharge by the temperature sensor inside the composite insulator sheath, we used silicone rubber plate as research object, and established a thermal model to realize the indirect calculation of surface temperature on the silicone rubber plate based on internal temperature. Firstly, according to the heat transfer theory, a thermal model of silicone rubber plate was established. Considering the influence of nonlinear factors in the process of atmospheric convection, the air convection index n was introduced to modify the model, and the solution method of convection heat transfer coefficient h was proposed. Then, temperature rise tests were carried out to simulate the heating condition of silicone rubber plate surface, and the temperature data of the upper and lower surfaces of silicone rubber plate were measured. The measured value of upper surface was compared with the calculated value of model. The results show that the relative error of the steady-state temperature of silicone rubber plate surface calculated by the model based on internal temperature is less than 10%, which meets the accuracy requirement.
