Embodiment Construction

[0025] figure 1 Shown is the schematic structural diagram of the terminal of the present invention, which is composed of terminal internal parts 1, terminal insulation cover 2, insulating layer 3 and connection terminal 4. The terminal inner part 1, the terminal insulation cover 2 and the insulating layer 3 are coaxially placed sequentially from the inside to the outside. The terminal inner part 1 is located on its central axis, followed by the insulation cover 2, and the outermost layer is the insulating layer 3. The connection terminal 4 is fixed on the outer end of the terminal inner part 1 .

[0026] The function of the terminal internal part 1 is to output a large current, connect electrical measurement signals, and input liquid nitrogen for cooling superconducting cables. The function of the insulation cover 2 is to prevent the ambient temperature from being transmitted to the superconducting cable in the terminal, so as to realize the requirement of low-loss operation....

Abstract

A high-temperature superconductivity cable terminal, including: the terminal inner parts (-), the terminal muff cover (-), the insulating layer (-) and the connection terminal (-); puts the terminal inner parts (-), the terminal muff cover (-) and the insulating layer (-) at the same axis in turn, the terminal inner parts (-) is located at the centre of the axes, and then is the terminal muff cover (-), the insulating layer (-) is at the outset layer. The terminal inner parts (-) consists of the liquid nitrogen liquid nitrogen conduit (-), the electric current lead (-), the flexible connecting line (-), the testing line (-), the inner cavity (-) and the sealing interface (-, -, -) between them. The electric current lead (-) connects with the inner cavity (-), the liquid nitrogen liquid nitrogen conduit (-) is located at the central axes of the electric current lead (-), the flexible connecting line (-) sets in the inner cavity (-), the testing line (-) is located at the out side of the electric current lead (-); the right end of the terminal inner parts (-) connects with the end part of the cable container (-);the liquid nitrogen liquid nitrogen conduit (-) inserts into the terminal inner cavity (-)from the inside of the electric current lead (-). Between the inner and outer two layer stainless steel tube (-, -) of the muff cover (-) puts the super heat-insulating material (-) and vacuumizes.
