Abstract

The invention provides a high-temperature superconducting cable electrifying conductor. The high-temperature superconducting cable electrifying conductor comprises a flexible framework; a first insulating layer which is spirally wound on the flexible framework; an A-phase superconducting layer which is formed by spirally winding a superconducting tape on the first insulating layer in a first direction at a preset winding angle theta; a second insulating layer which is spirally wound on the A-phase superconducting layer; a B-phase superconducting layer which is formed by spirally winding a superconducting tape on the second insulating layer in a second direction at a preset winding angle theta; a third insulating layer which is spirally wound on the B-phase superconducting layer; a C-phasesuperconducting layer which is formed by spirally winding a superconducting tape on the third insulating layer in a first direction at a preset winding angle theta; a fourth insulating layer which isspirally wound on the C-phase superconducting layer; a copper shielding layer which is spirally wound on the fourth insulating layer; a fifth insulating layer which is spirally wound on the copper shielding layer; and a protective layer which is spirally wound on the fifth insulating layer; wherein the first direction and the second direction are symmetrical about the central axis of the cable. The high-temperature superconducting cable electrifying conductor can reduce a circumferential magnetic field and homogenize the magnetic field, is suitable for occasions of short-distance power transmission, and realizes low-loss, high-efficiency and high-capacity power transmission.

Description

technical field [0001] The invention relates to the technical field of superconducting cables, in particular to an electric conductor of a high-temperature superconducting cable. Background technique [0002] High-temperature superconducting cable system is a power facility that uses unimpeded superconducting materials that can transmit high current density as a conductor and can transmit large currents. It has the advantages of small size, light weight, low loss and large transmission capacity. Realize low-loss, high-efficiency, large-capacity power transmission. The high temperature superconducting cable system will first be used in short-distance power transmission occasions (such as generators to transformers, substation centers to substations, underground substations to urban power grid ports) and short-distance transmission of large currents such as electroplating plants, power plants and substations. occasions, as well as large or very large urban power transmission ...
