Maglev train power system

Abstract

The invention provides a maglev train power system which comprises a levitating power deice, a control power supply provided with a direct current output end and an alternating current output end, and a battery pack. The battery pack is used for starting the control power supply and supplying power to the control power supply when a train ground power supply system fails in power supply. An input end of the levitating power device is connected to the train ground power supply system. An output end of the levitating power device is connected to a train-power first direct-current trunk network. Both the battery pack and the train-power first direct-current trunk network are connected with an input end of the control power supply. A first contactor is connected between the battery pack and the input end of the control power supply. The control power supply is used as a power supply for control systems and emergency systems in medium- and low-speed maglev trains. Two prior independent power systems are combined by optimization, the original power system is simplified, train weight is lowered, noise is lowered, and reliability of train electrical systems is improved.

Description

technical field [0001] The invention relates to power supply technology, in particular to a power supply system for a maglev train. Background technique [0002] The medium and low-speed maglev transportation system has a series of characteristics such as low noise, small vibration, no pollution, large climbing ability, strong line adaptability, and easy implementation. It is safe, reliable, and comfortable in the environment. It is especially suitable for complex terrain and high requirements for noise and vibration. , a city with a large flow of people but not suitable for the construction of subway or light rail lines. According to estimates by relevant experts, 10% of the lines that need to be built for subways or light rails in my country are suitable for the construction of medium and low speed maglev transportation systems. It can be seen that medium and low speed vehicles have broad market prospects. [0003] The medium and low-speed maglev trains at the present sta...

Problems solved by technology

[0006] The vehicle is equipped with two independent power supply units and two independent battery packs, including DC110V control power supply unit, DC110V battery pack and emergency inverter, DC330V suspension power supply unit, and DC330V battery pack. There are too many on-board power supply devices, which increases the weight of the train When all devices are running at the same time, the noise is large; the system reliability is not high
