유도가열 기술을 활용한 에너지 저감형 분기기 히팅시스템의 유효성 검증 = Validation of The Heating System for Saving Energy with Induction Heating Technology on Railway Switch

다국어 초록 (Multilingual Abstract)

Recently, when railways are opened in winter, the number of railway accidents tends to increase. Conventional rail heaters in railway switches consist of bus wires. Although it has the advantage of being simple and convenient, it consumes a lot of power, but the disadvantage is that it takes a long time to melt. In this paper, a commonly used Induction Heating(IH) technology is applied to the heating system of a railway switch to improve this. The electric power of the induction heater was targeted to be reduced compared to the conventional one. At the same time, induction heaters are designed in a similar size to replace rail heaters.
The inverter is designed to meet the operating frequency and output required by the induction heater. Based on this, multi-physics analysis and experiments using the prototypes were performed. In addition, it was confirmed that there is an energy-saving effect through frequency control compared to the conventional system.
