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.
