고속 종합 검측 시스템 도시철도 적용시 시스템 전원 공급 방안 연구

The company conducts regularly inspection for the safe transport of passengers such as catenary, track and signal sector in the railway company. Measuring and inspection vehicles imported 100% remain difficult maintenance in KOREA due to the fact that the vehicle was operating stop for a long time because of heavy broken and expensive components. In this paper, we propose power supply way of urban railway when equipped with high-speed inspection system in national R&D project. Furthermore, we researched the optimized power supply of the system due to the fact that we reviewed for load usage of measuring and inspection system and urban rail vehicle power supply margin.
