Axial forcing device and adjustment method for winding displacement of superconducting coil

Abstract

An axial forcing device for winding displacement of a superconducting coil comprises a support arm, a guide arm, a forcing spring, a wire pressing wheel, an angular displacement sensor and a signal processing module. The axial forcing device is fixedly installed at the top portion of a winding machine creel stand through the supporting arm, abuts tightly against the superconducting coil through the wire pressing wheel, applies axial pressing force, and is connected with a control component of a winding machine system through the angular displacement sensor and the signal processing module. The guide arm is wholly in a C-shaped structure, the upper end of the guide arm is hinged to the support arm, the middle portion of the guide arm is connected and fixed with the forcing spring, and the lower end of the guide arm is connected with the wire pressing wheel. The angular displacement sensor is used for measuring the included angle between the guide arm and the support arm, and the signal processing module is used for receiving real-time angle signals transmitted by the angular displacement sensor and real-time position signals of the winding machine creel stand, and regulating the operation of the winding machine creel stand. On the premise that an existing superconducting coil automatic winding displacement device is not changed, a few components are added, and accurate control of the inter-turn interval of the superconducting coil is achieved.

Description

technical field [0001] The invention relates to a coil winding force applying device and an adjustment method, in particular to an axial force applying device and an adjusting method for automatic wire arranging during the superconducting coil winding process. Background technique [0002] Due to the existence of the electromagnetic effect during the electrification process of the superconducting coil, the huge current will cause a strong magnetic field around the magnet. Under the action of the magnetic field force, the axial and radial directions of the coil will be subject to tension or pressure, which is manifested on the single wire of the magnet as the tensile stress inside the superconducting wire and the inter-turn axial thrust between the superconducting wires. The superconducting wire will deform or move under the action of external force, and the local movement of the superconducting wire will cause the superconducting wire to suddenly lose its superconducting pro...
