The invention provides a power supply system for intercity rail vehicles, and the system comprises a power supply system conversion switch, a trunk line power supply, an urban power supply, a voltage processing unit and a super capacitor. When an intercity rail vehicle operates in a trunk line, one end of the power supply system conversion switch is connected to the trunk line power supply; the other end of the power supply system conversion switch is connected to the voltage processing unit; a voltage output by the trunk line power supply is adjusted and then is supplied to a to-be-powered device in the intercity rail vehicle. When the intercity rail vehicle operates in an urban area, one end of the power supply system conversion switch is connected to the urban power supply; the other end of the power supply system conversion switch is connected to the super capacitor; the super capacitor obtains electric energy from the urban power supply when the vehicle arrives at a station in order to power the to-be-powered device. The trunk line power supply and the urban power supply are switched via the power supply system conversion switch; the to-be-powered device is powered by the energy stored in the super capacitor in the urban area; and an overhead line system does not need laying in the urban area. The system is resource-saving and environment-friendly and also avoids hidden dangers caused by the overhead line system to urban safety.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a power supply system for intercity rail vehicles. Background technique [0002] With the expansion of cities and people's wider travel needs, urban rail transit tools such as subways and light rails that are only suitable for cities can no longer meet the needs of urban expansion. As a resource-saving, environment-friendly, safe and convenient large-capacity public transportation mode, intercity (city) rail transit will play an important role in the future intercity passenger transportation between central cities, new cities, and satellite cities in my country's major cities. [0003] The existing intercity rail vehicles still use catenary (third rail) power supply mode during operation. However, with the development of cities and the continuous expansion of the coverage of intercity rail transit, the contact power supply method not only has a negative impact on the beauti...
