摘要： PROBLEM TO BE SOLVED: To provide a field winding of a high temperature superconducting generator which is hardly affected by field component of the (c) axial direction, and can do without decreasing mean current density when critical current density is part decreased by field components in the (c) axial direction. SOLUTION: Pancake type coils 3, on which high temperature superconductive tapes 2 are flatly wound are laminated in the radial direction, and a field winding is constituted. Tapes 14, 13 whose critical current densities to a magnetic field in the (a) (b) axes directions or the (c)-axis direction are large are arranged so as to be suitable for a magnetic field condition. In the part where critical current density is small, a number of the high temperature superconductive tapes 2 which are aligned in parallel is increased, or the sectional area is enlarged, thereby preventing partial decrease of critical current density which is to be caused by a magnetic field in the (c) axis direction. Nevertheless when a part in which critical current density is remarkably decreased exists, the high temperature superconductive tape 2 is not wound around the part, and electrical conduction to good conductor is constituted.

摘要： PURPOSE:To detect firing angle shift of a converter installed in an AC/DC converting station by taking out converter currents for three phases and comparing nontheoretical every order harmonic current with a predetermined level through a CPU. CONSTITUTION:Three-phase bus side current waveforms for an AC/DC converter is read, in the form of digital amount, into a CPU 13 through an input selector 12 and an A/D converter 17 and subjected to harmonic analysis based on Fourier series principle in order to calculate every order harmonic current component. An abnormality decision is made when nontheoretical every order harmonic current component in the AC/DC converter produced through firing angle shift exceeds a predetermined level, and a signal is delivered to an alarm 16. Consequently, firing angle shift in each of three phase AC/DC converters can be detected accurately during operation. This monitor can deliver an alarm quickly upon occurrence of abnormality and contribute to safe operation of the system.

摘要： PURPOSE:To prevent degrading of critical current and generation of resistance and connect superconductive wires easily by laminating a pair of exposed tube- like filaments of a compound-type superconductive each other to form a connection part and heating at the temperature at which superconductive is formed. CONSTITUTION:A Sb3Sn multisuperconductive strand 10 comprises a stabilizing matrix of Cu 1 in which 264 of tube-like Nb filaments 5 composed with Nb tubes 2 containing 1wt.% of Tl and composites of Sn wires 3 with 30% concentration and Cu coatings 4 which are packed in the Nb tubes are distributed. The matrix at the end of the strand 10 is dissolved in nitric acid to exposure Nb filaments 5. The exposed parts of two of the strands 1 are twisted to form a connection part 11. A Cu supporting material 12 is placed the surroundings of the connection part 11 and heated (at 450 deg.C) under pressure to alloy the Sn and Cu in the filaments 5. Then, heating is further carried out in vacuum at the temperature at which Sb3Sn is formed to complete connection.

摘要： PURPOSE:To maintain the temperature of electrical parts constant by arranging an oxide superconductor in the vicinity of superheatable electrical parts and connecting them to each other. CONSTITUTION:A heating element 1 is covered with an oxide superconductor 5 in which a critical temperature is 300 deg.K or above, they are connected in series, and a circuit connected to a main power source is made into a main power source circuit. When the heating element 1 is superheated, the superconductor 5 is transferred to a normal conductive state, a current is made small, and the temperature of the heating element 1 is lowered. When the temperature is sufficiently lowered, the superconductor 5 is made into the superconductor again, the heating element 1 is heated by conduction, and the temperature is maintained constant.

摘要： PURPOSE:To obtain a permanent-current switch, turn-off and turn-on times thereof are each shortened, by winding a plural layer of heater wires along superconducting wires so that the heater wires are interposed among the windings of the superconducting wires. CONSTITUTION:An annular switching casing 10 is dipped into a cryogenic medium 11 such as liquid helium and cooled. Heater wires 13 are rolled into superconducting wires 12 so that the heater wires 13 are interposed among pairs of the superconducting wires 12 folded back by bifilar winding in the switch casing 10. The heater wires 13 are formed by flexible band-shaped stainless foil in approximately 10mum thickness, and a plural layer of them are wound along the superconducting wires 12. The number of the steps of windings wound in the longitudinal direction of tabular heater wires 13b is increased, thermal conduction to the superconducting wires 12 from both heater wires 13a, 13b is improved, thus reducing temperature differences among 13 and 12. Accordingly, a permanent-current switch can be turned-off by low inputs while the turn-off and turn-on times of the switch can also be shortened.

摘要： PURPOSE:To reduce a maximum stress of a coil and to make the coil small and lightweight by a method wherein wound layers which are not bonded to each other are formed at the inside from a prescribed wound layer. CONSTITUTION:In a superconducting coil in which a plurality of layers of superconducting conductors have been wound in a radius direction, pancake elements 4 and insulations 3 between pancakes are bonded firmly by using an epoxy-based resin adhesive, and interlayer insulations 1 and conductors 2 at individual layers are bonded to each other. On the other hand, the insulation 1 and the conductor 2 are set as mutually unbonded layers at innermost diameter layers 5 at the inside from a position R1 where an expansion force in a radius direction becomes maximum; the expansion force in the radius direction is not transmitted from an adjacent layer and a concentration of a stress is relaxed. As a result, a cross-sectional area of an innermost-layer coil is made small and the coil can be made lightweight and small.
