Method for improving stability of high temperature superconducting magnetic suspension system

Abstract

A method for increasing the stability of a high-temperature superconductor magnetic suspension system comprises the following: (A) a step of field cooling, during which, a suspension body of the high-temperature superconductor magnetic suspension system is supported at a preset position through a support system, and then refrigeration equipment is started to ensure that a superconducting block enters superconducting state; (B) a step of support release, during which, the support system releases the support on the suspension body so as to ensure that the suspension body is in an idling stable state; (C) a step of loading, during which, external force is applied on the suspension body so as to ensure that the suspension body is in a stable suspension state under external force loading; and (D) a step of loading and the external force release, during which, the suspension body is in the stable suspension state again, and the state is taken as an initial state for the operation of the high-temperature superconductor magnetic suspension system. The method does not need to change the construction of the high-temperature superconductor magnetic suspension system, and ensures simple structure and operation and cost reduction; moreover, the method can obviously improve the stability of the high-temperature superconductor magnetic suspension system, and is suitable for any high-temperature superconductor magnetic suspension systems based on the high-temperature superconducting block type magnetic suspension principle.

Description

technical field [0001] The invention relates to the performance improvement of a high-temperature superconducting magnetic levitation system, in particular to a method for improving the stability of the high-temperature superconducting magnetic levitation system. Background technique [0002] The high-temperature superconducting magnetic levitation system is mainly divided into two application directions: if the axisymmetric rotary motion is used in the fields of bearings or flywheels; if the translational symmetric linear motion is used as a magnetic levitation (maglev) device for parallel motion, Such as linear motor conveyors and magnetic levitation vehicles. At present, the technological research in these two aspects is already on the eve of large-scale practical application. Various high-temperature superconducting maglev prototypes have been developed and successfully tested. Since 2000, China, Germany, and Russia have developed manned maglevs. High-temperature superc...

Problems solved by technology

[0006] However, limited by the current high-temperature superconducting block material preparation technology and magnetic material technology, there is not much room for improving the stability of the high-temperature superconducting maglev system in methods two and three; There is also limited room for improvement in stability

Moreover, during the implementation of the above methods, it is usually necessary to change the components of the high-temperature superconducting maglev system. The implementation process is relatively complicated, the cost is large, and the effect is not ideal.
