Abstract: Electric point heating system (hereinafter referred to as point heating system) provides a strong guarantee for the safe operation of high-speed railways in winter. In the actual application of point heating system, it is found that when the point heating effect is insufficient and the system needs to be reinforced, factors such as insufficient power and power capacity of the existing point heating isolation transformer will limit the reinforcement of the system. The power module can effectively solve such problems. This paper introduces the working principle of power module and describes the advantages of adding a power module to point heating system.

Key words: electric point heating system, power module, point heating isolation transformer
