Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Nb 3 The structure of Al superconducting joints, such as figure 1 As shown, by the first multi-core Nb 3 Al wire 1, the second multi-core Nb 3 Al wire 2 joint pipe 3 components.

[0033] The first multi-core Nb 3 One end of Al wire 1 and the second multi-core Nb 3 One end of Al wire 2 is connected, the first multi-core Nb 3 The other end of the Al wire 1 and the second multi-core Nb 3 The other end of the Al wire 2 is wound into a magnet coil and connected.

[0034] The joint pipe 3 and the joint end cover 4 are made of oxygen-free copper with a residual resistivity (RRR value) greater than 150.

[0035] The first multi-core Nb 3 Al wire 1 and the second multi-core Nb 3 The connected end of the Al wire 2 is arranged in the middle of the joint pipe. The joint end cap 4 is arranged on one end of the joint pipe 3 , and a compre...

Abstract

The invention discloses an Nb3A1 superconductive connector which comprises two multi-core Nb3A1 superconductive wires, wherein one end of the first multi-core Nb3A1 superconductive wire is connected with one end of the second multi-core Nb3A1 superconductive wire, and the other end of the first multi-core Nb3A1 superconductive wire and the other end of the second multi-core Nb3A1 superconductive wire are wound to form magnet coils and connected. A manufacturing method of the Nb3A1 superconductive connector comprises the steps that one end of the first multi-core Nb3A1 superconductive wire and one end of the second multi-core Nb3A1 superconductive wire are wound to form the magnet coils and connected; the other end parts of the first multi-core Nb3A1 superconductive wire and the second multi-core Nb3A1 superconductive wire are washed cleanly; and copper on the surfaces of the other end parts are eroded off till superconductive core filaments are exposed out completely, and are encapsulated in a connector pipe. The Nb3A1 superconductive connector is low in contact resistance, so that heat of a magnet generated due to the fact that the resistance of the connector is too high can be reduced; the magnetizing time of the magnet is shortened; and the stability of the magnet is improved. The manufacturing method is short in manufacturing cycle and simple.

Description

technical field [0001] The invention belongs to the technical field of superconducting magnets and relates to a Nb 3 Al superconducting joint, the present invention also relates to the manufacturing method of the superconducting joint. Background technique [0002] Since the discovery of superconductivity in 1909, superconducting materials and their application technologies have developed rapidly. In the field of scientific research, high-field magnets, nuclear magnetic resonance magnets for analysis, accelerator magnets, and particle detector magnets are widely used. Nuclear fusion energy is an ideal energy source with unlimited resources, clean and safe. It is precisely because of the abundant resources and environmental friendliness of controllable nuclear fusion energy that it is recognized as one of the effective technical means to solve the future global energy crisis and promote the sustainable development of human society. The full superconducting magnetic confine...
