Abstract

The invention discloses a high-temperature superconducting conductor. Each high-temperature superconducting conductor comprises a superconducting wire core, a metal foil and a metal sheath. The superconducting wire core comprises a metal framework and a superconducting tape group. According to the superconducting wire core, the structure that the superconducting strips are arranged on the outer side is adopted, large critical current can be obtained on the premise that the sectional area of the superconducting strips and the sectional area of the metal framework are not changed, and thereforethe engineering current density is improved, and the stability of a superconducting conductor can also be improved through the structure; and the critical current can be flexibly adjusted by adjustingthe proportion of the sectional areas of the superconducting tape and the metal framework in the superconducting conductor according to specific power transmission or magnet application requirements,so that the operation economy of the superconducting conductor is improved.

Description

Technical field [0001] The invention relates to the technical field of superconducting conductor application, in particular to a high-temperature superconducting conductor. Background technique [0002] As the power system develops toward greater system capacity, and the power grid develops toward large-scale and ultra-large-scale development, superconductivity has the advantages of extremely low power transmission loss, high current density, and strong current carrying capacity. Application becomes possible. With the second generation of REBCO (REBa 2 Cu 3 O z ) The successful development of high-temperature superconducting tape, the development of superconductivity technology has grown stronger, and superconducting equipment such as superconducting cables, superconducting transformers, superconducting current limiters, and superconducting generators have appeared successively. At present, the development of superconducting cables is very rapid, but the development of supercond...
