Railway transportation power supply construction

摘要

A railway transportation power supply construction comprising a power supply rail and a return current rail respectively secured on two sides of an insulating base and isolated by the insulating base. A power supply arm and a return current arm are mounted to a bogie of a vehicle and insulated from the vehicle body by means of insulation rings, the bogie provided with a drive mechanism. The power supply arm has a front end connected to one end of an input port of the drive mechanism, and a terminal end in contact with the power supply rail. The return current arm has a front end connected to the other end of the input port of the drive mechanism, and a terminal end in contact with the return current rail. During operation, the power supply arm has friction with the power supply rail to be powered, and the return current arm has friction with the return current rail, enabling the vehicle to travel through a junction section with uninterrupted power supply while the structure and operating condition of a junction remain unchanged.
