The invention provides a ground power supply system for an electric vehicle, and the system comprises a ground power supply module which is disposed between two steel rails, and comprises a ground power supply positive electrode module and a negative electrode backflow contact rail; the electricity receiving shoe is arranged at the bottom of the electric vehicle, and the electricity receiving shoe comprises a positive electrode electric brush and a negative electrode electric brush; wherein the anode electric brush is in sliding contact with the ground power supply anode module, the cathode electric brush is in sliding contact with the cathode backflow contact rail, so that the ground power supply module supplies power to the electric vehicle through the power receiving shoe, and the cathode backflow contact rail is grounded, so that stray current generated during backflow of the cathode of the power supply module is limited in the ground power supply module. Therefore, electric corrosion damage of stray current to sleepers and steel rails is avoided. Through the negative electrode module, the ground power supply system does not generate stray current to the outside, and railway facilities are protected from being damaged.
本公开提供了一种电气车辆的地面供电系统,包括:地面供电模组,地面供电模组设置在两条钢轨之间,且包括地面供电正极模块和负极回流接触轨;受电靴,受电靴设置在电气车辆的底部,受电靴包括正极电刷和负极电刷;其中,正极电刷与地面供电正极模块滑动接触,负极电刷与负极回流接触轨滑动接触,以用于地面供电模组通过受电靴为电气车辆供电,负极回流接触轨接地,以使供电模组负极回流时产生的杂散电流限定在地面供电模组内,以避免杂散电流对枕木和钢轨产生电蚀损坏。本发明通过负极模块,使地面供电系统对外部不产生杂散电流,保护铁路设施不受损坏。
