Abstract:

We study the heat transfer performance of the railway switches and establish a calculation model for minimum heating power at different snow melting positions under different environment conditions. The calculation model provides the reliable theory for the engineering applications of electric heating snow-melting system.

Key words: railway switch, snow-melting system, electric heating, minimum heating power
