Summary:The invention provides a heat effect analysis method and device for a superconducting coil in an over-current state. The method comprises the following steps: measuring the temperature of a superconducting strip in a superconducting direct current limiter and the corresponding resistivity at the temperature; calculating the calorific value of the superconducting tape according to the temperature of the superconducting tape and the corresponding resistivity at the temperature; calculating the heating power of the heat source at each moment according to the heating value of the superconducting strip; constructing a simulation model of the superconducting DC current limiter according to the heating power of the heat source at each moment; and calculating the heating power of the simulation model of the superconducting direct current limiter by adopting multi-physical field simulation software. By adopting the above method, the heat production-resistivity corresponding relation is deduced by using the heat accumu
