High current density circular stacked HTS degaussing cable structure

Abstract

The invention relates to a high-current-density circular stacking type high-temperature superconducting demagnetization cable structure which can bear large current, wherein the structure belongs to the field of a high-temperature superconducting demagnetization cable. The high-temperature superconducting demagnetization cable comprises a core body, an insulating layer, an isolating strip, a liquid nitrogen channel, a low-temperature dewar pipe and an outer protective sleeve, wherein the core body, the insulating layer, the isolating strip, the liquid nitrogen channel, the low-temperature dewar pipe and the outer protective sleeve are successively arranged from inside to outside in a radial direction. The core body is obtained through stacking superconducting belts. According to the structure of the invention, the stacking type cable core body structure is utilized, and current density of a current carrying conductor can be further improved. The high-current-density circular stacking type high-temperature superconducting demagnetization cable structure has advantages of realizing smaller weight and size, simplifying structure and realizing easy production.

Description

technical field [0001] The invention relates to a circular stacked high-temperature superconducting degaussing cable structure capable of carrying large currents with high current density, belonging to the field of high-temperature superconducting degaussing cables. Background technique [0002] Newly built and repaired ships, as well as ships that have been used for a certain period of time, must be degaussed to defend against attacks by magnetic weapons (such as magnetic induction mines) in water and to be discovered by magnetic detection instruments to ensure the safety of ship navigation. There are two methods of degaussing: (1) Temporary coil degaussing method: used to offset the inherent magnetic field of the ship, performed by the degaussing ship and degaussing station. The degaussing station or ship is equipped with degaussing generator sets, degaussing coils, magnetic field detection equipment, control devices, etc. Generally, the degaussing cable should be wound o...
