    摘要： A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.

    摘要： A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed within the refrigerator for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device being positioned within the refrigerator advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.

    摘要： A cryogenic refrigerator for cooling a rotating device includes a stationary regenerator, and a rotatable cold heat exchanger coupled to the stationary regenerator to rotate relative thereto. The cryogenic refrigerator is, for example, of the Gifford-McMahon type or pulse tube type. In the Gifford-McMahon type, a stationary cylinder houses the regenerator, and a rotatable cylinder mounted to the cold heat exchanger is concentrically arranged about the stationary cylinder. Alternatively, the rotatable cylinder is axially offset of the stationary cylinder. A seal, for example, a ferrofluidic seal, is located between the stationary and rotatable cylinders. In the pulse-tube type, a pulse tube is concentrically arranged about the regenerator, and the cold heat exchanger includes a stationary portion coupled to the regenerator and a rotatable portion coupled to the pulse tube. A back-up valve system is provided for increased reliability.

    摘要： An HTS cable assembly is provided which includes a cryostat or housing, an HTS wire bundle disposed longitudinally within the cryostat, and plural support members disposed between the HTS wire bundle and the cryostat. The support members are elongate, tubular members having resiliency in both the axial and radial directions. The support members are disposed between the HTS wire bundle and the inner surface of the cryostat in an arrangement that maintains and supports the HTS wire bundle in a spaced-apart relationship with respect to the inner surface of the cryostat. In addition, the plural support members are configured to substantially prevent relative movement between the HTS wire bundle and the cryostat.

    摘要： A method and system for providing protection for a superconducting electrical cable located in a utility power network includes detecting a fault current on the superconducting electric cable, determining the cumulative total energy dissipated in the superconducting electrical cable from the fault current and at least one prior fault current over a predetermined time period, and determining whether to disconnect the superconducting electrical cable from the utility power network on the basis of the cumulative total energy dissipated.

    摘要： A method of controlling fault currents within a utility power grid is provided. The method may include coupling a superconducting electrical path between a first and a second node within the utility power grid and coupling a non-superconducting electrical path between the first and second nodes within the utility power grid. The superconducting electrical path and the non-superconducting electrical path may be electrically connected in parallel. The superconducting electrical path may have a lower series impedance, when operated below a critical current level, than the non-superconducting electrical path. The superconducting electrical path may have a higher series impedance, when operated at or above the critical current level, than the non-superconductor electrical path.
