Abstract
A racetrack shaped high temperature superconducting (HTS) coil is fabricated by layer winding HTS tape under tension on a precision coil form with a binder such as pre-preg filament-ply interlayer insulation. The coil form includes a racetrack shaped bobbin, two side plates and a series of blocks that define the outside surface of the coil. The outside surface of the winding is over-wrapped with a copper foil bonded to heat exchanger tubing. The coil is baked in the coil form to cure the epoxy then released from the coil form. The resulting coil structure is a strong winding composite built to close tolerance dimensions.
Claims17
An apparatus for manufacturing high temperature superconducting (HTS) coils, the apparatus comprising:
- two side plates disposed in facing relation;
- a bobbin disposed between the side plates, the bobbin receiving layers of HTS tape interposed with a binder;
- and
- a plurality of blocks assembled adjacent an outer edge of the side plates, the blocks being displaceable toward the bobbin to compress the layers of HTS tape on the bobbin.
A method of manufacturing high temperature superconducting (HTS) coils with an apparatus including two side plates disposed in facing relation, a bobbin disposed between the side plates, and a plurality of blocks assembled adjacent an outer edge of the side plates, the blocks being displaceable toward and away from the bobbin, the method comprising:
- (a) winding HTS tape onto the bobbin;
- (b) applying a binder to the wound HTS tape;
- (c) compressing the HTS tape and the binder against the bobbin with the plurality of blocks;
- and
- (d) baking the compressed HTS tape and the binder to thereby cure the binder.
