Embodiment Construction

[0013] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other; the present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0014] refer to figure 1 , a kind of superconducting cable proposed by the present invention, which includes a first cryostat tube 1, a superconducting wire 2 wound on the first cryostat tube 1, a second cryostat tube 3, and a third cryostat tube 4 from inside to outside. , braiding layer 5, shielding layer 6, sheath layer 7.

[0015] In a further embodiment, a copper wire 8 is also included, and the copper wire 8 is located in the first cryostat tube 1 . The copper wire 8 can also be used for power transmission without interfering with each other and improving the cable use effect. Using liquid nitrogen to cool the copper wire 8 reduces the resistance of the copper...

Abstract

The invention discloses a superconducting cable, which comprises a first cryogenic thermostat, a superconducting wire wound on the first cryogenic thermostat, a second cryogenic thermostat, a third cryogenic thermostat, a braiding layer, a shielding layer and a sheathing layer from the inside to the outside.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a superconducting cable. Background technique [0002] At present, there is resistance in the transmission line itself. When the load current passes, it will consume electric energy. The loss on the transmission line accounts for a large part of the loss, and with the different voltage levels, the loss ratio of the transmission line is also different. Some are as high as 82.7%. It can be seen that changing the loss of transmission lines is mainly an improvement of the line, so superconducting transmission cables have the advantages of large current-carrying capacity, low loss and small size, and are one of the important ways to solve large-capacity and low-loss power transmission. [0003] With the increasing electricity consumption in big cities, it is necessary to transmit a large amount of electric energy to the urban load center, and the use of high-voltage overhead lines to ...
