A ground charging station for energy storage rail transit vehicles

Abstract

Disclosed in the invention is a ground charging station for an energy storage type rail transport vehicle. The ground charging station comprises a high-voltage power distribution cabinet, a transformer, a charging device, a networking isolation switch cabinet, and a catenary; a switching device is arranged at a circuit between an input terminal and an output terminal of the networking isolation switch cabinet; the input terminal of the networking isolation switch cabinet is electrically connected with an output terminal of the charging device; and an input terminal of the catenary is electrically connected with the output terminal of the networking isolation switch cabinet. When the energy storage type rail transport vehicle stops in the station, an output terminal of the catenary is electrically connected with an energy storage power supply of the energy storage type rail transport vehicle; and the high-voltage power distribution cabinet, the transformer, the charging device, the networking isolation switch cabinet, and the catenary are arranged in the station. On the basis of arrangement, the ground charging station enables the weight of the rail transport vehicle to be effectively reduced and the space utilization rate of the rail transport vehicle to be effectively improved.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a ground charging station for energy storage rail transit vehicles. Background technique [0002] The energy storage type rail transit vehicle is a rail vehicle equipped with an energy storage power supply, and the energy storage power supply of the rail vehicle can store electric energy for traction power. Energy storage rail transit vehicles are suitable for urban traffic with frequent starts and stops, and there is no need to erect wires for power supply. Compared with traditional power transmission rail transit vehicles, energy storage rail transit vehicles can save the power loss of transmission lines. [0003] Energy-storage rail transit vehicles can be charged in the station during the stationary time at the station, and a ground power supply station is installed in the station of the rail transit vehicle, and the ground power supply station can charge the vehic...

AI Technical Summary

Problems solved by technology

[0005] However, since the charging and voltage regulating device of the energy storage type rail transit vehicle in the prior art is arranged on the vehicle, the self-weight of the vehicle is too large, the vehicle consumes more energy in operation, and the vehicle space occupied by the charging and voltage regulating device is relatively large , reducing vehicle space utilization

[0006] Therefore, how to solve the problems of high self-weight of energy storage rail transit vehicles and low utilization rate of vehicle space has become an important technical problem to be solved by those skilled in the art.
