Embodiment 1

[0037] This embodiment relates to a compact superconducting cable, comprising a sheath and at least one conductor core 1, a heat insulating layer 3 is arranged in the sheath, the conductor core 1 is arranged inside the heat insulating layer 3, and between the conductor core 1 and the heat insulating layer 3 There is a refrigerant channel, and there is an isolation part in the refrigerant channel. The isolation part separates the refrigerant channel into an inflow channel 5 for the inflow of the refrigerant, and an outflow channel 6 for the return flow of the refrigerant.

[0038] Based on the overall structural design above, a specific implementation of the compact superconducting cable of the present invention is as follows: figure 1 As shown, the sheath of the superconducting cable can adopt the existing mature sheath material, and the conductor core 1 has several twisted sets, preferably, the conductor core 1 has three twisted and fastened ones, The three conductor cores 1 ...

Embodiment 2

[0044] This embodiment relates to a cable assembly, including a compact superconducting cable as in Embodiment 1, and cable terminals arranged at both ends of the compact superconducting cable. cryostat.

[0045] Here, as a preferred embodiment, the cryostat is set at the position where the end of the superconducting cable turns back, so as to cool and exchange the heat-carrying working fluid that flows back, and the cryostats are installed at both ends The method is conducive to efficient cooling of the refrigerant in the inflow channel and the outflow channel, thereby helping to maintain a good working environment for the superconducting cable. However, the cryostat can adopt existing mature low-temperature refrigeration equipment, which will not be described in detail in this embodiment.

Abstract

The invention provides a compact superconducting cable and a cable assembly with the same, and belongs to the technical field of superconducting cables. The cable comprises a sheath and at least one conductor core; a heat insulation layer is arranged in the sheath, the conductor core is arranged in the heat insulation layer, and a refrigerant channel is formed between the conductor core and the heat insulation layer; an isolation part is arranged in the refrigerant channel and divides the refrigerant channel into an inflow channel for refrigerant to flow in and an outflow channel for the refrigerant to return and flow back. According to the compact superconducting cable provided by the invention, the backflow refrigerant channel is integrated in the superconducting cable, so that the working cost of the cable can be reduced, the influence of external heat on the refrigerant can be reduced, and the overall thermal load of a system is reduced.

Description

technical field [0001] The invention relates to the technical field of superconducting cables, in particular to a compact superconducting cable and a cable assembly having the same. Background technique [0002] Superconducting cable is a new type of large-capacity power transmission device developed by utilizing the characteristics of zero resistance and high current-carrying density of superconducting materials. Compared with conventional cables, the transmission capacity is increased by about 10 times under the same cross-section, and the transmission loss is reduced by 1 / 4-1 / 2, it has significant technical advantages in scenarios such as high-load density urban line expansion, new energy power transmission, and high-current industrial applications such as electrolysis. [0003] Although the shape of the three-core superconducting cable is relatively compact, which is equivalent to that of the three-phase coaxial type, an independent return pipe must be used to form a co...
