Embodiment 1

[0022] Such as Figure 1-2 As shown, a superconducting cable includes an outer insulating protective layer 1, a conduit 2 arranged in the outer insulating protective layer 1 and a superconductor 3 arranged in the conduit 2, and the conduit 2 is provided with a nitrogen inlet The pipe 4 and the nitrogen outlet pipe 5, the nitrogen inlet pipe 4 and the nitrogen outlet pipe 5 are arranged through the outer insulating protection layer 1, and the superconductor 3 is in a hexagonal grid shape and forms a tubular spatial topology. Compared with the traditional superconducting cable, by setting the superconductor 3 in the conduit 2 for transporting liquid nitrogen, the superconductor 3 can directly contact the liquid nitrogen, and the superconductor adopts a hexagonal grid-shaped and tubular spatial topology , high strength, the same sheet structure as graphite, has good electrical properties, and can make the superconductor fully contact with liquid nitrogen, so that the pre-cooling ...

Embodiment 2

[0025] Such as Figure 2-4 As shown, a superconducting cable includes an outer insulating protective layer 1, a conduit 2 arranged in the outer insulating protective layer 1 and a superconductor 3 arranged in the conduit 2, and the conduit 2 is provided with a nitrogen inlet The pipe 4 and the nitrogen outlet pipe 5, the nitrogen inlet pipe 4 and the nitrogen outlet pipe 5 are arranged through the outer insulating protection layer 1, and the superconductor 3 is in a hexagonal grid shape and forms a tubular spatial topology. The superconductor 3 is a copper oxide superconductor. The superconductor 3 is suspended in the conduit, which can facilitate the contact of the superconductor with liquid nitrogen and accelerate the cooling speed of the superconductor. Both the nitrogen inlet pipe 4 and the nitrogen outlet pipe 5 are integrated with the conduit 2, and both the nitrogen inlet pipe 4 and the nitrogen outlet pipe 5 are reliably connected to the conduit 2 and have a stable st...

Abstract

The invention discloses a superconducting cable. The cable comprises an external wrapping insulating protective layer, a conduit arranged in the external wrapping insulating protective layer and a superconductor arranged in the conduit, the conduit is provided with a nitrogen inlet tube and a nitrogen outlet tube, both the nitrogen inlet tube and the nitrogen outlet tube penetrate the external wrapping insulating protective layer, and the superconductor is of a hexagonal grid type and forms a tubular spatial topology structure. Precooling time, before use, of the superconducting cable is short.

Description

technical field [0001] The invention relates to a superconducting cable. Background technique [0002] Superconducting cables have low losses, which can reduce electricity running costs. Superconducting cables can carry three to five times more electricity than conventional cables, meeting the growing power needs of cities. Underground superconducting cables can replace overhead lines in environments where overhead lines cannot be installed. In special occasions, when the original conventional underground cables cannot be expanded, they can be replaced by superconducting cables, and closed busbars are also suitable for replacing by superconducting cables. [0003] Existing superconducting cables generally include an insulating sheath, a heat insulating layer, a superconductor, and a frame. The superconductor is arranged on the frame, and liquid nitrogen is generally transported from the frame. Such a structure is not conducive to the cooling of the superconductor. Long pr...
