Abstract

The invention discloses a high-temperature superconducting Rutherford cable. The cable comprises a conductor, a plurality of superconductive strands and a metal sheath. The plurality of superconductive strands are tightly and spirally wound on the outer wall of the conductor. The metal sheath is of a hollow structure, the conductor and the superconductive strands are arranged in the metal sheath, and the outer walls of the superconductive strands make contact with the inner wall of the metal sheath. A gap formed between the inner wall of the metal sheath and the outer wall of the conductor is filled with a cooling medium. The high-temperature superconducting Rutherford cable provided by the invention has the advantages that the thermal stability of the cable can be effectively improved, the installation space is saved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature superconducting Rutherford cable. Background technique [0002] With the increasing demand for electricity and the rapid development of the power industry, people have put forward higher requirements for the safety and reliability of the power industry and power quality. Stability and reliability can also greatly increase the capacity of a single machine and the transmission capacity of the power grid. Superconducting cable is currently the most promising superconducting power device in the field of superconducting power technology. The zero-resistance characteristic of superconductors makes the loss of power in the transmission circuit almost zero, and can realize low-voltage, high-current and high-density power transmission. Under the circumstances, superconducting cables can carry greater power than ordinary cables. In the past ten years, with the great imp...
