The present invention relates to an apparatus and method for supplying power for a railway signal. The apparatus for supplying power to loads for railway signals may comprise: a bus; a first power supply unit outputting a bus voltage, which is a direct current (DC) voltage, to the bus from one or more power sources; a second power supply unit connected to the bus and generating output voltages for supply voltages provided to the loads from the bus voltage; and one or more bypass circuit breakers connected to the second power supply unit. The second power supply unit may include: a first power module and a second power module which respectively generate a first output voltage and a second output voltage, which have the same size. The one or more bypass circuit breakers may include a first bypass circuit breaker which is configured to respectively transfer the first output voltage and the second output voltage to a first load and a second load in a normal mode, and to commonly transfer the first output voltage or the second output voltage to the first load and the second load in an emergency mode. Therefore, the stability of railway system can be improved.

    철도 신호용 부하들에 전력을 공급하기 위한 장치는, 모선(bus), 적어도 하나의 전원(power source)으로부터 모선에 DC(direct current) 전압인 모선 전압을 출력하는 1차 전원부, 모선에 연결되고, 모선 전압으로부터 부하들에 제공되는 공급 전압들을 위한 출력 전압들을 생성하는 2차 전원부, 및 2차 전원부에 연결된 적어도 하나의 바이패스 차단기를 포함할 수 있고, 2차 전원부는, 동일한 크기의 제1 출력 전압 및 제2 출력 전압을 각각 생성하는 제1 전력 모듈 및 제2 전력 모듈을 포함할 수 있고, 적어도 하나의 바이패스 차단기는, 정상 모드에서 제1 출력 전압 및 제2 출력 전압을 제1 부하 및 제2 부하에 각각 전달하도록 구성되고, 비상 모드에서 제1 출력 전압 또는 제2 출력 전압을 제1 부하 및 제2 부하에 공통으로 전달하는, 제1 바이패스 차단기를 포함할 수 있다.
