A production process of liquid helium-free skeleton superconducting magnet

Abstract

The invention discloses a production process of a liquid-helium-free and framework-free superconducting magnet, which solves the problem that a large number of superconducting magnets are scrapped if the superconducting magnet fails to pass the inspection during the production process at the present stage. The main point of the technical plan is a production process of a liquid helium-free and framework-free superconducting magnet, including: S1, producing superconducting coils through a winding machine; S2, after all superconducting coils of the superconducting magnet are produced, the superconducting The coil is installed on the mounting frame; S3, using superconducting joint technology to connect adjacent superconducting coils; S4, using a gauss meter to measure the magnetic induction intensity of the superconducting magnet; the production process of the liquid-free helium-free superconducting magnet can reduce Damage to superconducting wires when superconducting magnets generate defects, and improve the production efficiency of liquid helium-free skeleton-free superconducting magnets.

Description

technical field [0001] The invention relates to the field of nuclear magnetic resonance instruments, in particular to a production process of a liquid helium-free skeleton-free superconducting magnet. Background technique [0002] In the production process of the superconducting magnet of the nuclear magnetic resonance instrument, it is necessary to wind the superconducting wire on the skeleton of a superconducting magnet. refer to figure 1 , a superconducting magnet skeleton, comprising a skeleton main body 1', the skeleton main body 1' is arranged at intervals along its length direction with skeleton wire slots 11' for winding superconducting wires. [0003] At present, the steps of winding the superconducting wire on the skeleton of the superconducting magnet include: A1. Winding the superconducting wire in the skeleton wire slot 11' on one side of the superconducting magnet skeleton, using resin for each layer of superconducting wire wound Solidify the superconducting ...

AI Technical Summary

Problems solved by technology

[0004] During the winding process of the above-mentioned superconducting wire, it is easy to cause the insulation of the superconducting wire to break or the superconducting wire to break

If the defect point of the superconducting coil is on the surface of the superconducting coil, it can also be compensated by insulation repair or superconducting joint; but when the defect point of the superconducting coil is inside, it will often cause all defects on the entire superconducting magnet skeleton Superconducting coil scrapped
