Bearing of large cake-shaped high-temperature superconductive magnet

Abstract

A large scale loading plate for high temperature super conducting magnet includes inner canisters, outer canister and supporting clapboard. The supporting clapboard is of a thickness t in torus shape, with its inner hole matching to the outer boss of the inner canister and radial cooling channels along its two surfaces. The inner canister is of a height h equal to that of the two annular notchs on the outer canister, and equal to the total thickness of double pie loops and its spacers. There is a flute of depth h1 on the inner wall to the bottom of the inner canister, and a boss of height h2 on the outer wall to the top of the inner canister. Two inner canisters match together through the boss and the flute with the supporting clapboard fixing to the boss at the relation of h2=h1+t. There are cooling holes on the inner and outer canisters.

Description

technical field [0001] The invention belongs to the technical field of superconducting technology, and relates to a load-bearing device for a pie-type high-temperature superconducting magnet. Background technique [0002] High-temperature superconducting magnets (especially those working at 20K and below) have the advantages of high stability, high current density, and high critical magnetic field that low-temperature superconductors cannot achieve. It has broad prospects in application. [0003] The conductors currently available for winding high-temperature superconducting magnets include bismuth-based silver-coated strips (Bi-2223 / Ag, Bi-2212 / Ag) that have been commercially produced and YBCO-coated high-temperature superconducting strips that are currently under development. , the length is very limited, usually 100 meters to 200 meters, and the longer the conductor, the lower the yield of the product and the higher the corresponding price. Due to the strip structure an...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defect of poor mechanical properties of the existing high-temperature superconducting tapes in transverse extrusion resistance, and to provide a large-scale pie-type high-temperature superconducting magnet for the electromagnetic stress distribution of large-scale high-temperature superconducting magnets and the structural characteristics of the magnets. The force-bearing device can effectively avoid the damage caused by the axial extrusion force caused by the huge electromagnetic stress to the superconducting magnet, improve the axial anti-extrusion ability of the magnet, improve the axial mechanical strength of the magnet, and thus improve the large-scale high-temperature Mechanical Stability of Superconducting Magnets
