A high temperature superconducting magnet winding method

Abstract

A method for winding high-temperature superconducting magnet includes such step as winding magnet with a skeleton, winding odd-even single-cake coil through positive and reverse skeleton, and electrically connecting adjacent single-cake coil through internal connector or external connector. The inner thread head is fixed to the skeleton from the outside of the skeleton, and the skeleton rotates counterclockwise; The inner thread head of the second single cake coil enters the skeleton from the inner side of the skeleton and is used as a joint to connect the inner thread heads of the first and second single cake coils, and the skeleton rotates in a clockwise direction; The third single-cake coil is wound the same as the first single-cake coil, and the outer heads of the second and third single-cake coils are connected; The fourth single cake coil is wound identically to the second single cake coil, and so on. The invention compensates for the shortage of the length of the strip caused bythe processing technology and the processing cost, and has the characteristics of simple design of the winding tool, small performance degradation of the superconducting wire, simple and convenient winding process, etc.

Technical field: [0001] The invention belongs to the field of electrical engineering of superconducting magnets, and mainly relates to a winding method of high-temperature superconducting magnets. Background technique: [0002] High-temperature superconducting magnets have the advantages of simple low-temperature systems, low operating costs, higher stability, and high current density. They have broad application prospects in superconducting energy storage, magnetic separation, nuclear magnetic resonance imaging, strong magnetic fields, and superconducting motors. . [0003] Most of the superconductors used in high-temperature superconducting magnets are commercially produced bismuth-based silver-coated strips (Bi-2223 / Ag) or YBCO-coated high-temperature superconducting strips. Bi-2223 / Ag is mostly prepared by powder casing method, and YBCO is mostly prepared by thin film deposition technology. They all have certain mechanical brittleness and are easily damaged, and their p...
