Abstract

The invention discloses a high-field superconducting solenoid coil with dispersive stress and a winding method thereof. The superconducting coil is divided into a plurality of layers by a stainless support layer; the superconducting coil is firstly wound into a superconducting line layer from inside to outside according to a radial direction; the outer surface of the superconducting line layer is wound with stainless steel wires by 1-2 layers, wherein the stainless steel wire is the same as the superconducting line in diameter, therefore, a stainless steel wire support layer is formed. Then alternative winding is carried out in sequence, finally the outermost end of the superconducting coil uses rectangular stainless steel wires to wind a support structure at the end so as to strengthen the whole coil and form the whole superconducting solenoid coil with dispersive stress. The invention not only can reduce the stress concentration in the superconducting winding, but also can greatly reduce the quench exercise times of the coil, and effectively improve the density of running current of the magnet. The coil with the structure is suitable for a high-field superconducting magnet system, in particular to a 25 to 30 T high-field superconducting magnet system.

Description

technical field [0001] The invention relates to a high magnetic field superconducting magnet coil and its winding method, in particular to a high magnetic field superconducting solenoid coil with a dispersing stress support structure and its winding method. Background technique [0002] Superconducting magnets have the characteristics of small size, light weight, and low energy consumption. For the development of high-field superconducting magnet systems for physics, biomedical and other scientific research applications, superconducting magnets have greater advantages than hybrid magnets and pulsed magnets. At present, the development of large-scale superconducting magnets and nuclear magnetic resonance magnet systems with high magnetic fields of 25-30T is an important direction for the application and development of high-magnetic field superconducting magnets. Usually, high-field superconducting magnets are realized by a variety of superconducting wires in the form of non-...
