Embodiment Construction

[0044] According to the invention, a planar or flat coil shape of the racetrack type is to be used as the starting point for the production of the saddle coil winding. Corresponding coil shapes are known (see eg DE 199 43 783 A1); FIG. 1 shows an exemplary embodiment. The coil winding denoted there by the reference numeral 2' has opposite longitudinal side winding sections 2a' and 2d' and end-side curved winding sections 2b' and 2c' extending between them. The winding 2' should be made of one or more tape superconductors. To form the coil winding, the respective strip conductor is erected, that is to say wound around the winding center or winding center Z with its narrow side facing the winding plane, for example around a central winding core. In any one turn, one circumference of the conductor should be wound around the center Z once for 360°, or once for each of the two longitudinal side winding sections 2a' and 2d' and the end side winding sections 2b' and 2c', in the figu...

Abstract

Disclosed is a saddle-shaped coil winding which is formed onto an outer tube surface from a planar race track-type coil shape so as to be provided with axially extending winding sections on the longitudinal side and winding sections that extend therebetween, are located on the front side, and form winding overhangs. The individual windings of the coil winding are to be formed with at least one band-shaped superconductor which comprises especially high Tc superconductor material and whose narrow side faces the outer tube surface. In order to prevent unacceptable mechanical stresses of the conductor when forming the coil, the windings in the saddle shape have a circumferential length which is virtually unchanged from the length in the planar oil shape.

Description

technical field [0001] The invention relates to a saddle coil winding with superconductors on the outer surface of a tube, comprising axially extending straight winding sections and end-side winding sections bent between them at opposite end sides forming winding ends. Furthermore, the invention relates to a method for producing such a coil winding. A corresponding method for producing such a coil winding is known from JP 06-196314A. Background technique [0002] In the field of superconducting technology, saddle coil windings have long been used in high energy and particle physics or in electrical machines. Here, it is usually used to contain the traditional low transition temperature T C Conductors of metallic superconducting materials, the so-called Low-T C -Supralaitermaterial (LTS material for short). This means that the corresponding conductor can be bent relatively easily and without loss of its superconducting properties to include axially extending straight wind...
