AI Technical Summary
The challenge lies in the rational arrangement of heating units on the rail web to achieve good heating and energy-saving effects, especially in electromagnetic induction turnout snow melting devices. Existing technologies suffer from uneven rail heating and cost waste due to unreasonable spacing between heating units.
By establishing a solid heat transfer simulation model of the rail, simulation calculations were performed to obtain heating effect data of heating units at different spacings, the final arrangement distance of the heating units was determined, and an electromagnetic induction coil was used to integrate the heating unit into a heating device. The cable arrangement was simplified by cascading units.
It achieves uniform heating of the rails, improves the integration and installation performance of the heating device, reduces the number of cables, improves layout efficiency and maintainability, and ensures safety and energy saving.
