摘要: An elongated current limiting composite material comprising one or more high-temperature superconductor filaments and a second electrically conductive member, which may include a sheath of high bulk resistivity surrounding the filament. The current limiter exhibits dissipation in the range of 0.05-0.5 V/cm at currents of 3-10 times the operating current, thereby minimizing fault currents and improving recovery capability.

摘要: A superconducting conductor and its method of manufacture includes an electrical conductor having a thermal conductor attached to and along a length of superconductor member and separated from the superconductor member by an electrically-insulative material. The member may include a length of superconductor composite having superconducting material and a non-superconducting, electrically conductive matrix material. The electrical conductor is configured to control the manner in which the superconductor transitions from its superconducting state to its non-superconducting (i.e., normal) state due to, for example, a fault current condition. The electrically-insulative material has a thickness for allowing heat from the superconductor to be conveyed to the thermal conductor. The superconducting conductor may be used in conjunction with a superconducting current-limiting device.

摘要: In a current limiting arrangement based on a superconducting transformer (30), a load (21) can be supplied with power without any interruption by providing an auxiliary winding (14) in parallel with the superconducting primary winding (12) of the transformer (30). This auxiliary winding (14) carries the excess current in the event of a short circuit and allows the superconducting primary winding (12), which has been heated due to the current limiting, to cool down. Once the short circuit has been cleared, the latter winding can once again carry the rated current, without any losses, immediately. The auxiliary winding (14) is composed of a normally conductive material and has an additional stray impedance.

摘要: A cryostat for a superconducting transformer is provided that includes non-conducting load bearing insulation and is adapted for use with a superconducting transformer. In addition, the cryostat prevents the formation of closed loop stray currents on its outer case. The cryostat contains the winding sets and other related electrical equipment of a transformer. The cryostat generally comprises a cryogenic tank having an outer wall, a non-conducting liner, and a load bearing insulation layer disposed therebetween. The tank holds a liquid or gaseous cryogenic coolant into which the components of the transformer are immersed. A plurality of passages allow the passage of the limbs of the iron core of the transformer through the tank.

摘要: A cooling device for cooling of current leads (6, 7) in the bushings of a cryotank (1), wherein the current leads in the gas-filled part of the cryotank are designed as plate-formed sub-leads (12) surrounded by a casing (8) of insulating material with an inner open part of rectangular shape. Between all the sub-leads inside the cryotank there are arranged a number of rows of inclined transverse ribs (13a, 13b, . . . 13n, 14a, 14b . . . 14n) of insulating material. On the inner walls of the casing, facing the plate edges of the sub-leads, and at the ends of the transverse ribs, shelves (15, 16) are fixed whereby spiral cooling coils are formed around the current leads from the lower edge of the casing.
