Current heating type equipment heating prediction method and system and medium

The invention discloses a current heating type equipment heating prediction method and system and a medium. The current heating type equipment heating prediction method comprises the steps that the contact initial temperature T0 of current heating type equipment at the initial moment is collected; the method comprises the following steps: when the heating prediction of the current heating type equipment needs to be carried out, acquiring an environment temperature Ts, a load current I of the current heating type equipment and a time t of a current relative initial moment, and calculating a contact temperature T of the current heating type equipment by taking a contact initial temperature T0, the environment temperature Ts, the load current I and the time t as automatic variables and adopting a preset function model; wherein the preset function model is T = (a * I2 + Ts-T0) * (1-e-bt) + T0, T is contact temperature, I is load current, Ts is environment temperature, a and b are constant coefficients, t is time,
