Multi-stator traction high-speed maglev train system

Abstract

The invention discloses a multi-stator traction high-speed maglev train system. A plurality of linear motor sets are averagely dispersed on a magnetic levitation channel line; four linear stators of each linear motor set are concentrated together to drag a strip-shaped plate long rotor under the whole maglev train; the maglev train is continuously dragged to run in an uninterrupted seamless relaymanner; the distance between the magnetic suspension air gaps of about 8mm is small; the powerful magnetic levitation force and guiding force are generated between the strip-shaped electromagnet and the strip-shaped iron core; wireless power supply operation of the high-speed maglev train system is achieved through a high-voltage long-wire power supply system, a photovoltaic cell panel and a storage battery power supply system. Double braking of an electromagnetic braking system and a mechanical braking system of the high-speed maglev train is organically matched. The safety of the maglev train during high-speed operation is ensured, the stability and reliability of the maglev height of the train are improved through the mechanical positioning effect of the front pulleys and the rear pulleys, and a supporting pressure difference constant device enables the supporting pressure and resistance of the front pulleys and the rear pulleys to be small.

Description

technical field [0001] The invention relates to a high-speed magnetic levitation train system, specifically, a multi-stator traction high-speed magnetic levitation train system. Background technique [0002] At present, China's low- and medium-speed maglev trains have been successfully tested and commercialized, realizing the full coverage of China's maglev trains from research and development to application, and becoming one of the few countries in the world that have mastered this technology. However, low- and medium-speed maglev trains Compared with wheel-rail high-speed trains, the advantages of trains are not outstanding. Medium and low-speed maglev trains not only have high costs, but also have lower practical value than mature high-speed trains. However, the wheel-rail high-speed train cannot be further increased in speed due to the limitation of the wheel resistance, while the resistance of the maglev train is very small, and the speed is easy to increase. Therefore,...

[0002] At present, China's low- and medium-speed maglev trains have been successfully tested and commercialized, realizing the full coverage of China's maglev trains from research and development to application, and becoming one of the few countries in the world that have mastered this technology. However, low- and medium-speed maglev trains Compared with the wheel-rail high-speed trains, the advantages of the trains are not outstanding. The low- and medium-speed maglev trains are not only expensive, but also not as practical as the technically mature high-speed trains.

However, the speed of the wheel-rail high-speed train cannot be further increased due to the limitation of wheel resistance, while the resistance of the maglev train is very small, and the speed is easy to increase.

The maglev train scheme of existing technology in the world is made up of maglev system, guide system and traction system at present, and the existing technical scheme of three major systems is not perfect, and its shortcoming is: the one, the electromagnetic control technology of maglev system and guide system is complicated, The cost is high; the second is that the long stator of the linear motor of the traction system is composed of high-density distribution of copper and iron materials. The length of the long stator is equal to the length of the maglev train line. The copper and iron of the long stator is large, and the cost is very high

In addition, the contact power supply method of maglev trains using high-voltage wires has obvious defects, especially affected by the climate.
