Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The invention provides a rail car traction power supply system. When a rail car enters a station, a platform power supply device installed at the rail car station will contact a receiver on the rail car, thereby providing an energy storage power supply connected to the receiver. Charging, and then the energy storage power supply provides traction power for the rail car to ensure the normal operation of the rail car, no catenary is required, the structure...

Abstract

The invention provides a traction power supply system of a track car. When the track car enters a station, a station power supply device arranged on the track car station will make contact with a current collector on the track car, so that energy storage power sources connected with the current collector are charged, and then the energy storage power sources provide traction power for the track car to guarantee that the track car normally operates without arranging an overhead line system; in this way, the structure of the power supply system is simplified, and when the track car brakes, all generated braking energy will be recovered by the energy storage power sources, so that the utilization rate of energy is greatly increased, and heat discharged into the environment is reduced; moreover, because steel rails in the power supply system are only used as walking rails, reflowing is not borne any more, and electro-corrosion on roadside facilities is avoided.

Description

technical field [0001] The invention relates to the technical field of energy saving of rail cars, and more specifically relates to a traction power supply system for rail cars. Background technique [0002] At present, in the rail transit system, the traditional rail cars are usually contact rail cars, which use catenary or third rail power supply. When traction, the rail car absorbs energy from the catenary; Grid feedback electric energy. However, it has been found through research that when braking, when the network pressure rises due to the limited absorption capacity of the catenary, the rail car will switch to resistance braking or friction braking, so that the kinetic energy of the vehicle is converted into heat energy and wasted. It will cause environmental problems such as temperature rise in the tunnel; moreover, since the rails of the rail car also serve as running rails and return rails, it is easy to cause electrical corrosion to the facilities along the line, ...
