Effective thermal management measures are of great significance for improving the reliability of relay protection equipment. Firstly, the paper establishes a temperature calculation function for components based on the thermal superposition model, calculates the minimum heat dissipation distance between components, and converts the functional coordination of components into coordinate constraints. An optimised layout scheme for components is obtained quickly based on the minimum heat dissipation distance and coordinate constraints. The finite element simulation results show that the optimized layout significantly improves the temperature of the components, with a maximum temperature reduction of 8.6%. Then a component overheating warning strategy has been proposed based on state recognition. By monitoring the operating temperature of the components, the life accelerated decay ratio of the components is calculated, and the allowable operating time and alarm signal of the components at a specific temperature are combined to accurately reflect the operating status of the components.
