Abstract

The invention relates to a maglev traction device of a high-temperature superconducting high-speed maglev train, and belongs to the technical field of intelligent devices. The traction device comprises a high-temperature superconducting maglev device and a traction power device; the high-temperature superconducting magnetic levitation device comprises vehicle body rail holding frames installed onthe left side and the right side of a vehicle body bogie, magnetic conductive rails installed on ground rails on the left side and the right side, a feedback control system, an air gap position detection controller, high-temperature superconducting electromagnets and guide electromagnets, wherein the high-temperature superconducting electromagnets and the guide electromagnets are installed on thevehicle body rail holding frames respectively. The traction power device comprises an iron-core-free long-stator permanent magnet synchronous linear motor which comprises two stators, two rotors and two installation supports. Each stator is vertically installed in the center of a ground track, and each rotor is vertically installed between the two sides of the two stators and installed on a bogieof a vehicle body. The problems of large coil volume and weight, serious heating and easy insulation aging in a traditional magnetic suspension structure are avoided, and the structure of a magnetic suspension system is simplified.

Description

technical field [0001] The application relates to a magnetic levitation traction device of a high-temperature superconducting high-speed maglev train, which belongs to the field of high-temperature superconducting maglev trains. Background technique [0002] The magnetic levitation device of traditional maglev trains generally adopts a constant electromagnet. When the weight of the train increases and the levitation force of the maglev train needs to be increased, the power supply current of the electromagnet must be increased. This not only causes a sharp increase in the heat generation of the levitation device, but also may It will make the magnetic flux density of the electromagnet tend to be saturated, which is not conducive to the increase of electromagnetic attraction. In addition, the coils made of copper or aluminum wires often used in conventional electromagnets have small current capacity, generally less than 8A / mm 2 , to produce the required number of ampere-turn...
