    摘要: A method and apparatus for charging superconducting magnet coils using the Seebeck effect of thermoelectric materials. Superconducting magnet coils are wound from a superconducting material, such as niobium-titanium, and placed in a cryogenic dewar to cool the coil below the critical temperature at which the coil becomes superconducting. The coil can be charged by providing a suitable thermocouple junction outside the dewar and a reference thermocouple junction inside the dewar and connecting the junctions to the coil in a manner providing charging current flow to the coil in accordance with the Seebeck effect. This method is particularly desirable for use with lightweight magnet systems for use in such applications as magnetic levitation systems for trains, space applications, etc. where the present heavy switching power supplies are undesirable.

    摘要: A device for inductive current limiting of an alternating current consisting of an induction coil (2), which includes at least one winding and through which current flows, a body (3) made of a ceramic high-temperature superconductor arranged concentrically to the latter and having a centrosymmetrical form which is hollow in the interior, and having located in the interior of said body (3) a concentrically arranged core (4) made of a soft magnetic material of high permeability. In normal operation (rated current), the superconductivity of the body (3) is effective and impedance of the induction coil (2) is very low. With overcurrent (mains short-circuit) the superconductivity disappears and the impedance of the induction coil (2) reaches its maximum, current-limiting value.

    摘要: A system, based on superconducting wires and elements, is used to rapidly generate magnetic field intensities at designated points. The apparatus consists of primary and secondary magnet windings, especially arranged so as to produce rapidly increasing magnetic fields. The primary magnet, located at a distance from the operating area, is charged prior to operation, thus producing a low magnetic field at the said area. Energy transfer to the secondary winding is initiated by induction from the primary winding, thus causing transfer to current to produce a high magnetic field in the said area. This system has many applications, including uses as reconnection-guns and electromagnetic launchers.

    摘要: A pulsed transformer having a superconducting primary winding and a normal conducting secondary winding. The secondary winding is connected across a load. One side of the secondary winding has a switch in series to the load. A high energy storage inductor is connected in parallel across the switch. With the switch closed and the primary winding and storage inductor charged to their maximum capacity, a high level of current now flows through the switch. The primary is then caused to go into its normal conducting mode collapsing the primary field which induces current into the secondary winding. As the secondary winding current increases the high level of current normally flowing through the switch decreases to substantially zero. When the switch current reaches substantially zero, the switch can be opened without damage thereto releasing the high energy from the storage inductor into the load. The switch primary winding can be constructed from a high temperature superconductor for improved performance.

    摘要: A multi-phase electrical transformer includes a rotor-stator structure that provides varying-reluctance magnetic-field paths in which the magnetic fields pass through plural stator cores on which phased primary and secondary windings are mounted and through a rotor that includes two annular poles attached to cylindrical pole-connecting means. At least one of the annular poles includes at least one field concentrator member. An optional stationary field winding surrounds the pole-connecting means in the region between said pole-connecting means and the stator cores, and permits adjustment of power factor in primary or secondary windings. The structure permits separation of stator core and pre-formed windings for repair and permits the core and windings to operate at cooler temperatures without additional cooling apparatus. The device of this invention is capable of simultaneous operation as a transformer and a synchronous machine.
