Problems solved by technology

The copper skeleton is used as the support material in the middle of the spiral superconducting composite conductor. When the critical current is insufficient, the current density is lower than the other two superconducting composite conductors; The process is difficult; although the superconducting tape stacked conductors, the manufacturing process is relatively simple, but due to the large current-carrying stack thickness, it can only be wound on a cylinder with a large radius

Abstract

The invention discloses a high-temperature superconducting composite conductor containing an inner superconducting layer and an outer superconducting layer. The superconducting composite conductor includes the inner superconducting layer and the outer superconducting layer. The inner superconducting layer includes inner superconducting layer units and filling factors which are arranged in a metalskeleton. The outer superconducting layer includes outer superconducting units winding the metal skeleton and an insulating layer outside the outer superconducting units. The superconducting compositeconductor has a simple structure and comprehensive functions, has high current-carrying performance and high current density due to the influence of a spatial magnetic field of the inner superconducting layer and the outer superconducting layer, and can further achieve good current-carrying performance in a low-temperature environment, and alternating-current loss is reduced.

Description

technical field [0001] The invention relates to a superconducting wire, in particular to a large current-carrying high-temperature superconducting composite conductor with high current density. Background technique [0002] With the continuous advancement of high-temperature superconducting material preparation technology, a series of superconducting materials with excellent performance have come out. For example, the critical current of a single superconducting strip under the self-field can reach 200A, which has laid a foundation for the development of superconducting technology. . However, with the gradual increase in people's demand for large current-carrying power devices, the current carrying capacity of a single superconducting strip can no longer meet the needs of practical applications, and the simple parallel winding structure of multiple superconducting strips will cause problems due to wire branches. The small leakage reactance between the circuits will cause a ...
