Abstract
A composite strip for use in the manufacture of superconducting windings consisting of a thin layer of insulating material situated between two layers of metal. The composite strip may be used to form the winding on its own, or it may be used in conjunction with a separate strip conductor. If it is used on its own, one or more of the layers of the composite strip is made to be superconducting. If it is used with a separate superconducting strip, then the metal layers can be made of an alloy such as to assist in thermally stabilizing the superconducting strip. A winding made in such a manner.
Claims13
An electric winding comprising a plurality of turns of a strip conductor consisting of a layer of a material which can be rendered superconducting sandwiched between two metallic layers of equal thickness adapted to thermally stabilise the layer of material which can be rendered superconducting when it is in the superconducting state, and interposed between each turn of the strip conductor in the winding a composite strip comprising a layer of insulating material sandwiched between two layers of metal so as to occupy the neutral axis of the composite strip.
An electric winding comprising a plurality of turns of a strip conductor consisting of a layer of a material which can be rendered superconducting sandwiched between two metallic layers adapted to thermally stabilise the layer of material which can be rendered superconducting when it is in the superconducting state, and interposed between each turn of the strip conductor in the winding a composite strip comprising a layer of insulating material sandwiched between two layers of metal so as to occupy the neutral axis of the composite strip.
A composite strip conductor for use in the production of an electrical winding comprising a layer of material which can be rendered superconducting sandwiched between two metallic layers adapted to thermally stabilise the sandwiched layer when it is in the superconducting state and wherein the outer surfaces of the layers of thermally stabilising metal have formed thereon a plurality of flat-topped protrusions of equal height so that a plurality of cooling channels can be formed throughout the winding through which a cooling medium can be caused to circulate.
