Abstract

The invention relates to a superconducting conductor support with high heat dissipation efficiency, which comprises an overall support frame and interlayer support bodies, and is characterized in thatthe overall support frame comprises a plurality of layers of cylindrical walls which are made of metal materials and have a certain thickness, and each layer of cylindrical wall is provided with circumferentially symmetrical superconducting conductor channels; a central cooling channel is formed in the central hollow part of the overall support frame; the interlayer supporting bodies are made ofmetal materials, located between the two adjacent layers of cylinder walls and used for supporting the cylinder walls, a certain space is reserved between the two adjacent layers of cylinder walls, and the two adjacent layers of cylinder walls of the overall supporting frame and the interlayer supporting bodies form a plurality of interlayer cooling channels. The superconducting conductor supportis made into a twisted structure, and liquid nitrogen channels are reserved between layers, so that the heat exchange efficiency of the twisted superconducting conductor can be greatly improved, and the influence of a vertical field around the superconducting conductor on the performance of the superconducting conductor can be reduced.

Description

technical field [0001] The invention relates to a novel superconducting cable support, in particular to a superconducting conductor support with high heat dissipation efficiency. Background technique [0002] Compared with conventional cables, high-temperature superconducting cables have the advantages of high current-carrying capacity and low transmission loss, and have development potential in large-scale power transmission. Superconducting cables with large transmission capacity and high current-carrying capacity have good application prospects. [0003] Due to the limited current carrying capacity of a single conductor, the application of multiple conductor twisted structures can increase the current density. Therefore, it has become an important development trend to use multiple conductor twisted structures to construct superconducting cable energized conductors. However, the conventional superconducting conductor support generally only leaves a liquid nitrogen channe...

AI Technical Summary

Problems solved by technology

However, the conventional superconducting conductor support generally only leaves a liquid nitrogen channel in the center of the support, and the outer layer superconducting conductor is relatively far away from the liquid nitrogen channel, which has the problems of slow cooling speed, low efficiency, and inability to dissipate heat in time when the cable heats up; if The superconducting conductor support is made into a twisted structure, and liquid nitrogen channels are left between the layers, which can greatly improve the heat transfer efficiency of the twisted superconducting conductor
