Abstract

The invention provides an electromagnetic levitation structure for a maglev train. The electromagnetic levitation structure includes a plurality of superconducting levitation frames and a plurality of normal conduction levitation frames arranged at intervals at the bottom of the car body of the maglev train, wherein: the superconducting levitation frame includes The superconducting magnet, the low-temperature Dewar and the first support structure are used to provide the suspension suction force between the magnetic levitation train body and the suspension track; the normal conduction suspension frame includes the normal conduction magnet, the iron core and the second support structure, which are used for The suspension air gap between the car body of the magnetic levitation train and the suspension track is adjusted. In the hybrid electromagnetic levitation structure of superconductivity and normal conduction proposed by the electromagnetic levitation structure used for maglev trains provided by the present invention, the superconducting magnet provides the main magnetic field for suspension, and the constant conduction magnet provides the magnetic field for adjusting the air gap, which has a large levitation air gap Moreover, the advantage of low suspension loss can reduce the requirements for smoothness of the track, which is conducive to line construction and line cost reduction, and is also conducive to the static floating of the maglev train and the simplification of the electromagnet cooling system.

Description

technical field [0001] The invention relates to the technical field of high-speed maglev traffic levitation systems, in particular to an electromagnetic levitation structure for maglev trains. Background technique [0002] For a constant conduction electromagnetic suspension (EMS) train, no matter the train is running or stationary, the train can be suspended, so the constant conduction electromagnetic suspension system is suitable for both low-speed maglev trains and high-speed maglev trains. However, the levitation force of the constant conduction electromagnetic levitation train is provided by the constant conduction levitation electromagnet. Since the constant conduction has a certain resistance, the levitation will consume part of the power and generate heat, and the heat dissipation performance of the levitation electromagnet is not good. This has become the constant conduction maglev system. one of the engineering problems. [0003] In addition, the power of the susp...
