Problems solved by technology

Among them, the current-carrying conductor is the current-carrying part of the high-temperature superconducting cable, and is the core component of the superconducting cable system. A circumferential magnetic field is generated between the layers, and the strength of the magnetic field at different positions is uneven, which affects the power transmission of the superconducting cable

Abstract

The invention provides a manufacturing method of a high-temperature superconducting cable electrified conductor. The manufacturing method comprises the following steps: providing a flexible framework;spirally winding a first insulating layer on the flexible framework; spirally winding an A-phase superconducting layer on the first insulating layer in a first direction by using a superconducting tape; spirally winding a second insulating layer on the A-phase superconducting layer; spirally winding a B-phase superconducting layer on the second insulating layer in a second direction by using a superconducting tape; spirally winding a third insulating layer on the B-phase superconducting layer; spirally winding a C-phase superconducting layer on the third insulating layer in the first direction by using a superconducting tape; spirally winding a fourth insulating layer on the C-phase superconducting layer; spirally winding a copper shielding layer on the fourth insulating layer; spirally winding a fifth insulating layer on the copper shielding layer; and spirally winding a protective layer on the fifth insulating layer. The superconducting cable electrified conductor manufactured by the method 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 a method for manufacturing an electrified 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 l...
