Abstract

The present invention provides a method for realizing magnetic suspension state through adoption of a closed loop constant current high-temperature superconducting coil which takes places of the novel superconductive suspension mode of high-temperature superconductor materials. The high-temperature superconductor materials are wound on a coil framework through a certain winding method (a drying winding method and a wet winding method), a closed loop structure is formed by employing the superconduction welding technology; and the closed loop high-temperature superconducting coil (1) is disposed in the low-temperature container and is located at the upper portion of a high-intensity magnetic field source, and field cooling enters the superconducting state. The superconducting coil has zero resistance property in the superconducting state, the induced current forms a constant current state in the closed loop high-temperature superconducting coil and maintains the interaction between an induced magnetic field and the high-intensity magnetic field source so as to realize passive and self-stable suspension similar to the high-temperature superconductor materials suspension.

Description

technical field [0001] The invention belongs to superconducting technology, in particular to a novel suspension mode formed by a strong magnetic field source and a closed-loop high-temperature superconducting coil, and relates to the high-temperature superconducting suspension field. technical background [0002] Below its critical temperature, high-temperature superconductors mainly exhibit two characteristics of zero resistance and diamagnetism. Based on the above two characteristics, there are two types of superconducting bulk materials and superconducting tapes. Superconducting tapes made of superconducting materials can withstand large currents due to their zero-resistance properties. Compared with traditional conductors (copper, aluminum, etc.), superconducting strips can transmit large currents without loss, which has broad application prospects in power systems and energy. Among them, superconducting magnets made of superconducting strips can generate strong magnet...
