A Transposition Method for Winding Two Parallel Superconducting Tape Spiral Coils

Abstract

The invention belongs to the electrical application field of super-conduction, in particular to transposition method of two parallel superconducting tapes during winding of a solenoid coil. At least two superconducting tapes are provided. The transposition method comprises the steps as follows: step one, the two superconducting tapes are wound along the top end of one axial side of a coil framework after overlapped vertically; step two, when the two superconducting tapes are wound to one fourth of the axial height of the coil framework, first time transposition is performed; step three, the two superconducting tapes are wound backwards continuously in an axial direction of the coil framework after overlapped vertically again; step four, when the two superconducting tapes are wound to three fourths of the axial height of the coil framework, second time transposition is performed; step five, one layer of an insulating material is wound around a completed winding layer after the two superconducting tapes are overlapped vertically again; and step six, whether the number of the winding layers of the superconducting tapes is equal to a set value is judged, if not, the former five steps are repeated, and otherwise, winding is stopped. With the adoption of the transposition method, the capacity of a superconducting coil can be improved, and the stability of the superconducting coil is enhanced.

Description

technical field [0001] The invention belongs to the field of superconducting engineering applications, and in particular relates to a transposition method for winding two superconducting strip material spiral coils in parallel. Background technique [0002] The application of superconducting and strong electricity is a very important aspect in the application of superconducting technology, and superconducting coils, as the key technology for strong electricity applications, are the core components of many superconducting power devices, such as superconducting magnets and superconducting generators , Superconducting motors, superconducting transformers, superconducting current limiters, etc. [0003] Generally, there are two winding methods for high-temperature superconducting coils: solenoid coil and double pie coil. Since the double pie coil requires two single pies to be welded in series, contact resistance is unavoidable. The current passing through the superconducting ...
