The invention discloses a steel rail backflow device for a direct-current traction power supply system and a detection system. The steel rail backflow device comprises a T-shaped busbar, a first moving contact, a second moving contact, a first shunt, a second shunt and a steel rail insulation joint; the steel rail insulation joint comprises an insulation sheet and a steel rail fishplate which arearranged at a seam of a steel rail; the T-shaped busbar comprises a first port, a second port and a third port; the first port and the second port are both static contacts; the first port and the second port are connected with the moving end of the first moving contact and the moving end of the second moving contact respectively; the first moving contact is connected with one end of the steel railinsulation joint through the first shunt and a cable; and the second moving contact is connected with the other end of the steel rail insulation joint through the second shunt and a cable. Connectionor disconnection between the T-shaped busbar and the steel rail insulation joint is achieved by moving the first moving contact and the second moving contact. Through the arrangement of all modules and the connection between the modules, the steel rail can be electrically segmented conveniently and quickly under the condition of not changing the whole-line electrical connection state of an existing main line steel rail, and stray current is prevented from being generated to the maximum extent.
