Embodiment Construction

[0053] The same components are denoted by the same reference symbols in the various drawings.

[0054] figure 1 The shown superconductors are based on known embodiments. In this case, both so-called monocore superconductors and multifilament superconductors as shown in the drawing can be involved. Such a superconductor 2 has a plurality of superconducting conductor cores or wires 3i embedded in a matrix 4, which consists of a normally conducting material. The conductor core 3i is made of MgB 2 Made of high temperature superconducting materials. Known materials used for the matrix are either elements (eg Cu, Ni, Ag, Fe, Wo, Al) or alloys, in particular alloys of these elements (eg CuNi, AgMg, CuSn, CuZn or NiCr).

Abstract

The superconductive connecting device (10) is used to contact the end pieces (12, 22a) of two superconductors (12, 22), each of which has at least one conductor lead (3i, 13, 23) that is made of a superconductive MgB2 material and embedded in a matrix (4) made of a normally conductive material, the conductor lead being directly sheathed with a barrier material (5). In a connecting region (8), the conductor leads (3i, 13, 23) of the end pieces (12a, 2a), which are at least partially stripped of the matrix material (4) and the barrier material (5), are arranged inside a sleeve (6) or bushing (9), and a magnesium diboride (MgB2) material is additionally present as a superconductive contacting material (7) which is located at least in some partial regions between the conductor leads (3i, 13, 23). For establishing the connection (10), the cross-section of the sleeve (6) or bushing (9) filled in this way is reduced.

Description

technical field [0001] The invention relates to a superconducting connection for end pieces of at least two superconductors, each having a matrix of normally conducting material and at least one superconducting MgB embedded in the matrix. 2 Conductor cores of (magnesium diboride), wherein, in a bushing or sleeve in a connection zone, [0002] - the conductor core of the end piece is at least partially stripped of the matrix material, and [0003] - There is also MgB as superconducting contact material 2 , the MgB 2 At least in the subregions between the conductor cores. [0004] A corresponding superconducting connection and a method for producing such a connection are available from WO 2007 / 128635 A1. Background technique [0005] Use low temperature (Low-T c ) superconducting material or high temperature (High-T c ) Superconductors of superconducting materials are usually made into single-core conductors or multi-filament conductors with a limited conductor length. ...
