Abstract

The embodiment of the invention provides a railway vehicle. The railway vehicle comprises a direct current bus, an auxiliary converter connected with the direct current bus, a charger connected with the auxiliary converter, and a superconducting magnet energy storage device connected with the charger; when the direct current bus provides direct currents, the auxiliary converter converts the directcurrent into an alternating current to supply power to the charger, the charger converts the alternating current provided by the charger into a direct current to charge the superconducting magnet energy storage device, and the superconducting magnet energy storage device stores energy; and when the direct current bus has no direct current, the superconducting magnet energy storage device suppliespower to a direct current load connected with the charger. According to the embodiment, the technical problems that a traditional energy storage device of a railway vehicle is heavy and large in sizeare solved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a rail vehicle. Background technique [0002] With the gradual maturity of the large-capacity, high-density, public transportation organization model of the railway sector and the improvement of various measures for the convenience and benefit of the people, it has become more and more people's choice to travel by low-carbon, environmentally friendly, and green high-speed rail vehicles. choose. In the case that the railway sector invests a large number of rail vehicles in operation, it is of great practical significance to effectively control or reduce the energy consumption of rail vehicles and make use of them. [0003] figure 1 It is a schematic diagram of the principle of a traditional rail train. Such as figure 1 As shown, the rail vehicle is provided with a storage battery 10 and a braking resistor 20 . The storage battery 10 is mainly responsible for ...
