A high current density rectangular stacked high temperature superconducting degaussing cable structure

Abstract

The invention relates to a high current density stacked high temperature superconducting degaussing cable structure which can load high current, and belongs to the field of high temperature superconducting degaussing cables. A core body, an insulating layer, an isolating tape, a liquid nitrogen channel, a low-temperature Dewar tube and an outer protective sleeve are arranged in the radial direction of a high temperature superconducting degaussing cable from inside to outside, wherein the core body is formed by stacking superconducting tapes. According to the high current density stacked high temperature superconducting degaussing cable structure, a stacked cable core body structure is adopted, so that the current density of a current-carrying conductor can be further improved; the high current density stacked high temperature superconducting degaussing cable structure has lower weight and smaller size; moreover, the structure is simplified and the production is facilitated.

Description

technical field [0001] The invention relates to a rectangular 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 woun...
