Abstract

The invention relates to a bismuth-series high-temperature superconducting wire component and a preparation method thereof. The superconducting wire component comprises at least two single superconducting wires with superconductivity, the width surfaces among the single superconducting wires are parallelly connected together in an electrical contact manner, and at least one metal reinforcing band is parallelly connected on the outer width surface of each of the two outermost superconducting wires in parallel connection. In order to further improve mechanical strength of the superconducting wire component, at least one metal coating with the mechanical strength higher than that of single metal reinforcing band is coated on the outer surface of the superconducting wire component. The superconducting wire component prepared by the method is high in mechanical strength and critical current.

Description

technical field [0001] The invention relates to a superconducting wire assembly, in particular to a high-temperature superconducting wire assembly prepared by using a bismuth-based high-temperature superconducting material and a metal reinforcing tape and a preparation method thereof. Background technique [0002] Bismuth-based high-temperature superconducting tape is currently the only high-temperature superconducting material that can be produced on a large scale. Superconducting cables, superconducting motors, superconducting current limiters, and superconducting magnetic separators made of bismuth-based high-temperature superconducting tapes are used. Major breakthroughs have been made in the research and development of products such as superconducting maglev trains and superconducting energy storage systems, and many projects have entered the stage of prototype trial operation. Bismuth-based high-temperature superconducting strips are made by Powder-In-Tube (PIT) method...
