The present invention relates to an electric railway power supply system, which comprises: an electric connection unit (100) disposed on an upper end of a railway vehicle (10), having a predetermined width, and disposed in a longitudinal direction of the railway vehicle (10); a power supply line (200) disposed to be inclined downward from an upper end of an electric pole (20) disposed at regular intervals along a railway track, and having one end (210) to be in contact with the electric connection unit (100) of the railway vehicle (10) when the railway vehicle (10) is close; a guide unit (300) installed on an upper end of the railway vehicle (10), and guiding the power supply line (200) to allow the power supply line (200) to be in stable contact with the electric connection unit (100); and a power supply line protection device (400) for protecting the power supply line (200) to allow one end (210) of the power supply line (200) to be exposed to the outside only when the railway vehicle (10) is close, based on interaction with the guide unit (300). Accordingly, the possibility of an electric malfunction of the power supply line due to contamination or rain or dust can be minimized.

    본 발명은 전기철도 전원공급 시스템에 관한 것으로서, 철도차량(10)의 상단에 배치되며, 소정의 폭을 가지고 상기 철도차량(10)의 길이 방향으로 배치되는 전기 접속부(100); 철도선로를 따라 일정간격으로 배치된 전주(20)의 상단으로부터 하측으로 경사지게 배치되며, 철도차량(10)의 근접시, 일측 단부(210)가 상기 철도차량(10)의 전기 접속부(100)에 접촉되는 전원공급라인(200); 상기 철도차량(10)의 상단에 설치되어, 상기 전원공급라인(200)이 상기 전기 접속부(100)에 안정적으로 접촉되도록 상기 전원공급라인(200)을 가이드하는 가이드부(300); 및 상기 가이드부(300)와의 상호 작용에 의거하여, 상기 전원공급라인(200)의 일측 단부(210)가 철도차량(10)의 근접시에만 외부로 노출되도록 상기 전원공급라인(200)을 보호하는 전원공급라인 보호장치(400)를 포함함으로써, 전원공급라인이 오염되거나, 강우 또는 먼지 등으로 인한 전기적인 오작동 가능성을 최소화할 수 있는 장점이 있다.
