Disclosed is a streetcar line thawing apparatus for a DC traction power supply system. The streetcar line thawing apparatus for a DC traction power supply system of the present invention includes: a power supply substation which supplies electric power to a first streetcar line and connects the electric power returned to a second streetcar line to a streetcar line sub-feed line; a power connection substation which forms a closed loop in which the first and second streetcar lines are electrically connected, to return the power supplied from the power supply substation through the first streetcar line to the power supply substation through the second streetcar line; and a control module which controls the power supply substation and the power connection substation, to remove ice formed on at least one of the first and second streetcar lines.

    직류 급전계통 전차선 해빙 장치가 개시된다. 본 발명의 직류 급전계통 전차선 해빙 장치는 제 1전차선에 전력을 공급하고 제 2전차선으로 귀환하는 전력을 전차선 부급전선에 연결하는 전원공급 변전소; 상기 제 1전차선과 상기 제 2전차선이 전기적으로 연결되는 폐루프를 형성하여 상기 전원공급 변전소로부터 상기 제 1전차선을 통해 공급된 전력을 상기 제 2전차선을 통해 상기 전원공급 변전소로 귀환시키는 전원연결 변전소; 및 상기 전원공급 변전소 및 상기 전원연결 변전소를 제어하여 상기 제 1전차선과 상기 제 2전차선 중 적어도 하나에 형성된 결빙을 제거하는 제어 모듈을 포함하는 것을 특징으로 한다.
