摘要： An electric coil includes bifilar pancake coils electrically connected to an adjacent pancake coil so that current flowing in adjacent turns of adjacent pancake coils flows in opposite directions at all radial region of the coil assembly. The superconducting fault current limiter is configured to provide a minimized inductance and low resistance in a normal state of operation. On the other hand, when a fault current exceeds a predetermined threshold, the resistance increases to a level sufficient for limiting the flow of fault current to a desired level until a circuit breaker connected within the electrical system opens the circuit.

摘要： A cable includes a plurality of bundles of insulated electrical conductors, each bundle having a first conductor, a second conductor, and a third conductor in a layered configuration. The first conductor of each bundle is connected in parallel to the first conductor of the remaining bundles, the second conductor of each bundle is connected in parallel to the second conductor of the remaining bundles, and the third conductor of each bundle is connected in parallel to the third electrical conductor of the remaining bundles. In addition, within each bundle, the first, second and third electrical conductors are configured so that a magnetic field generated in response to currents flowing within the bundle is zero as seen at a plane oriented transverse to an electrical conduction direction of the cable and located between the ends of the cable.

摘要： The invention provides an apparatus for supplying power to superconducting loads includes a current source, a cryogenic region (e.g., a cryogenic chamber), a first switching device in series between the current source and a superconducting load, and a second switching device in parallel with the superconducting load. The switching devices are arranged so that, when the first is closed and the second is open, recharging current is supplied to the superconducting load. The second switching device serves as a shunt. When it is closed and the first is open, current recirculates through the persistent (or partially persistent) superconducting load. The invention also provides a superconducting magnet incorporating such a power supply.

摘要： A rotor assembly for use within a superconducting electric motor includes a superconducting winding formed of high temperature superconductor and during operation, generates a flux path within the rotor assembly; and a high permeability magnetic material, positioned within at least a portion of the flux path so as to decrease the overall reluctance of the flux path. The rotor assembly may include a support member having an internal volume and formed of a non-magnetic, high-strength resilient material. The support member supports on its outer surface the superconducting winding and within its internal volume, the high permeability magnetic material. The magnetic material may be in the form of a core member to provide the low reluctance portion to the flux path generated by the superconducting winding.

摘要： This invention relates to a practical superconducting conductor based upon biaxially textured high temperature superconducting coatings. In particular, methods for producing flexible and bend strain-resistant articles and articles produced in accordance therewith are described which provide improved current sharing, lower hysteretic losses under alternating current conditions, enhanced electrical and thermal stability and improved mechanical properties between otherwise isolated films in a coated high temperature superconducting (HTS) wire. Multilayered materials including operational material which is sensitive to bend strain can be constructed, in which the bend strain in the region in which such operational material is located is minimized. The invention also provides a means for splicing coated tape segments and for termination of coated tape stack ups or conductor elements. In one embodiment, a multi-layer high temperature superconductor is provided and includes first and second high temperature superconductor coated elements. Each element includes a substrate, at least one buffer deposited on the substrate, a high temperature superconductor layer, and a cap layer. The first and second high temperature superconductor coated elements are joined at the first and second cap layers.

摘要： The invention relates to a high-temperature superconductor lead element including a plurality of lengths of high-temperature superconductor electrically connected in a non-collinear configuration, for example, next to and parallel with each other, to increase the thermal length of the lead element. A proximal end of a first of the lengths is configured for thermal connection to a warm thermal element and a distal end of a last of the lengths is configured for thermal connection to a cold thermal element. Each length of high-temperature superconductor includes a high-temperature superconductor plate having an electrically insulative support and a plurality of high-temperature superconductor tapes mounted, in a linear array, on the support. A plurality of high-temperature superconductor plates are arranged with their longitudinal axis parallel to form a cylindrical lead with "bad" self-fields in each plate being substantially cancelled by self-fields in neighboring plates.
