Embodiment Construction

[0037] As previously stated, in one aspect, the present invention includes a coil wound from a cable comprising a plurality of strands, one or more of which are different from one or more strands in one direction along the length of the cable. The pitch angle of the other strand helix is ​​helical and the strands are braided above and below each other along the length of the cable, at least one of the strands comprising an HTS tape conductor.

[0038] Figures 1 to 3One cable embodiment consisting of eight strands, each strand comprising a single HTS tape conductor, suitable for winding the coils of the present invention is shown. Along the length of the cable, four of the HTS strip conductors 1 through 4 spiral in one direction (clockwise around the length of the cable) and the other four HTS strip conductors 5 through 8 in the opposite direction (counterclockwise) (same direction and orientation) used to refer to the direction of rotation of the wire along the length of the...

Abstract

An HTS coil is wound from a cable comprising multiple HTS tape conductor strands. The HTS tape conductor strands spiral along a length of the cable with a different pitch angle to one or more other strands, and are braided over and under one another along the length of the cable. The coils may be produced with fully transposed and thus magnetically decoupled HTS tape windings without the need forHTS materials.

Description

technical field [0001] The present invention relates to a coil wound from a cable comprising a plurality of HTS tape conductors and a method of manufacturing the same. Background technique [0002] High Tc superconductors (HTS) are used in coils of high field transformers, magnets, motors, generators and fault current limiters, for example, where they require an application-specific optimum combination of: a) high current carrying capacity, b) high current density, c) low AC loss and d) stability. For a given type of HTS wire, a) and b) can be improved by increasing the number of wires, while AC losses can be reduced and stability improved by ensuring that the cable is fully transposed so that each wire is electromagnetically equivalent . In this way, current is shared equally and AC losses are minimized. Also, many HTS wires are thinner ceramic coatings on metal tape substrates. Due to this form factor, they exhibit anisotropic mechanical properties (eg minimum turning ...
