The present invention relates to a power supply circuit for an engine warming apparatus, and more specifically, to a power supply circuit for an engine warming apparatus, preventing power from being applied to an unused socket when external power is connected through a plurality of external power supply sockets to supply the power to an engine warming apparatus of a diesel-electric locomotive, so as to prevent an accident in advance. The features of the present invention comprises: the engine warming apparatus; a first and a second engine warming sockets connected to the external power to supply the power to the engine warming device; and an interlock contact device installed between the first and the second engine warming sockets, and the engine warming device to connect the power. The interlock contact device selectively connects a power line of the first or second engine warming sockets to a device line connected to the engine warming device.

    본 발명은 엔진예열장치 전원공급 회로에 관한 것으로, 보다 상세하게는 디젤전기기관차 엔진예열장치 전원공급을 할 때 외부 전원공급용 복수 소켓을 통해 외부 전원을 연결할 시, 사용하지 않는 소켓에 전원이 인가되지 않도록 하여 안전사고를 미연에 방지할 수 있도록 하는 엔진예열장치 전원공급 회로에 관한 것이다. 이와 같은 본 발명의 특징은 엔진예열장치; 상기 엔진예열장치에 전원을 공급하기 위해 외부전원이 연결되는 엔진예열소켓1 및 엔진예열소켓2; 상기 엔진예열소켓1 및 엔진예열소켓2와 엔진예열장치 사이에 구비되어 전원연결하는 인터록접촉기를 포함하며, 상기 인터록접촉기는 엔진예열장치로 연결되는 장치회선, 엔진예열소켓1 및 엔진예열소켓2의 전원선 중에서 어느 하나의 전원선을 선택적으로 연결시키는 것을 특징으로 한다.
