Railway vehicle charging system

Abstract

The invention provides a railway vehicle charging system, and the system comprises a geothermal power generation device used for generating power by using geothermal energy; an energy emitting devicewhich is connected with the geothermal power generation device, and the energy emitting device is arranged on the rail; an energy receiving device which is arranged on the rail vehicle, wherein the geothermal power generation device transmits electric energy to the energy transmitting device, and the energy transmitting device provides the electric energy for the energy receiving device in a magnetic resonance coupling mode so as to charge the rail vehicle. According to the rail vehicle charging system, renewable clean energy can be reasonably utilized for power generation, wireless power supply is conducted on the rail vehicle through the independent power grid, and therefore, the complexity of rail transit power supply is reduced, environmental protection is facilitated, and the convenience of rail vehicle charging is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail vehicle charging system. Background technique [0002] At present, in the rail transit system, the power traction system of rail vehicles is mostly guaranteed by a complex power supply system, which is introduced through the urban power grid or power station using high-voltage cables and transformers, and then passed through a series of electrification equipment, such as medium-voltage Cabinets, rectifier transformers, rectifiers, low-voltage cabinets, DC switch cabinets, etc., to convert high-voltage power into direct current for rail transit. [0003] However, the above scheme through a series of electrical equipment and power supply protection system involves many modules and equipment, the whole system is huge, and the cost is high. The solution and the various protection functions of the circuit lead to a long construction period of this kind of scheme, a wide r...
