Problems solved by technology

[0004] However, since the electric energy that can be stored by supercapacitors is low, and the electric energy consumed by rail vehicles is relatively large, the electric energy stored in supercapacitors can usually only drive the vehicles for a few minutes. When the power supply system is separated from the power supply system for a long time, the supercapacitor alone cannot provide the initial voltage source for the long-distance operation of the vehicle, so it will affect the safe operation of the rail vehicle

Embodiment Construction

[0020] An embodiment of the present invention provides a power supply device for a hybrid rail vehicle, and the power supply device includes a supercapacitor and a battery pack.

[0021] The supercapacitor and the battery pack are connected in parallel, and are respectively connected to the power supply system in the vehicle, and are used to provide a power supply voltage source for the power supply system in the vehicle when the catenary is disconnected from the power supply system of the vehicle.

[0022] A hybrid rail vehicle is a vehicle in which two or more power sources provide an initial voltage source for the vehicle's power supply system.

[0023] The power supply system in a vehicle is a device that converts the voltage provided by the initial voltage source into the voltage required by the traction motor in the vehicle. The power supply system usually includes a pantograph, a traction converter, and a control unit. The function of the pantograph is to introduce the ...

Abstract

The invention provides a power supply device and a power supply system of a hybrid railway vehicle, and a railway vehicle, wherein the power supply device comprises a super capacitor and a storage battery bank; the super capacitor is connected in parallel with the storage battery bank; and the super capacitor and the storage battery bank are connected to the power supply system in the vehicle, respectively, thereby providing a power supply voltage source for the power supply system in the vehicle in a state that a contact network is separated from the power supply system of the vehicle. The power supply device is characterized in that the characteristics of the super capacitor and the storage battery bank are combined and the super capacitor and the storage battery bank are connected in parallel, so that the electric energy output by the super capacitor and the storage battery bank serves as the power supply voltage source for the power supply system together when the contact network is separated from the power supply system or the contact network has a power failure; and the electric energy needed for driving the vehicle to run can be conterminously output for a long time and power supply to the traction motor of the vehicle through the power supply system for a long time can be realized; and therefore, safe running of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to electrical control technology, in particular to a power supply device, a power supply system and a rail vehicle of a hybrid rail vehicle. Background technique [0002] A hybrid rail vehicle is a vehicle in which two or more power sources provide the initial voltage source for the vehicle's power supply system. At present, in a hybrid rail vehicle, the catenary + on-board supercapacitor is mainly used as the initial voltage source of the vehicle power supply system. The traction motor is powered through the power supply system to drive the traction motor, thereby providing traction power for the vehicle through the traction motor. [0003] In this form of power supply system, when the catenary has power, the catenary is used as the initial voltage source to supply power to the traction motor to drive the traction motor; when the vehicle power supply system is separated from the catenary or the catenary has no power, the supercap...
