The present invention describes various embodiments related to an electric railroad power supply system which is able to, in order to supply power in a power supply line to an electric access unit of a railroad vehicle in a stable manner, make the electric access unit electrically come in contact with the power supply line without abrasion. According to an embodiment of the present invention, the electric railroad power supply system can comprise: an electric access unit placed on an upper end of a railroad vehicle, and placed in a longitudinal direction of the railroad vehicle; a power supply unit placed on a plurality of electric poles placed along a railroad at regular intervals and supplying power to the electric access unit in accordance with an electric contact when the railroad vehicle comes near; and a line contact unit placed on an end of the power supply line and rolled when being pressed by elastic force so that the electric access unit can electrically come in contact with the power supply line.

    본 발명은 전원공급라인의 전원을 안정적으로 철도 차량의 전기 접속부에 공급하기 위해 상기 전기 접속부와 상기 전원공급라인이 마모 없이 전기적으로 접촉시키는 전기철도 전원 공급 시스템과 관련된 다양한 실시예들이 기술된 바, 한 실시예에 따르면, 전기철도 전원 공급 시스템은, 철도 차량의 상단에 배치되고, 상기 철도 차량의 길이방향을 향하여 배치되는 전기 접속부; 철도 선로를 따라 일정간격으로 배치된 복수개의 전주들에 배치되고, 상기 철도 차량의 근접시 전기적 접촉에 따라 상기 전기 접속부에 전원을 공급하는 전원공급라인; 및 상기 전원공급라인의 끝단에 배치되고, 상기 전기 접속부와 상기 전원공급라인이 서로 전기적으로 접촉하기 위해 탄성력에 의해 가압됨과 아울러 롤링되는 라인 접촉부;를 포함할 수 있으며, 이외에도 다양한 다른 실시예들이 가능하다.
