摘要： PROBLEM TO BE SOLVED: To improve reliability of a superconducting magnet against quench prevention by reducing eddy current heat generation due to magnetic field change caused by vehicle oscillation during traveling. SOLUTION: The thickness of a low electrical resistance material layer 20 is partly changed, where the layer covers a surface or is plated on the surface of a superconducting coil accommodating vessel 2 which cools a superconducting coil 1 and fixes it to a specified position. In particular, the thickness of low electric resistance material layers 21, 22 of levitating direction upper side region where an eddy current is liable to be generated by magnetic field change of low frequency is increased, and the electric resistance value is reduced. A radiant heat shield and a vacuum thermal insulation vessel which surround the accommodating vessel 2 may be constituted of low electric resistance material in which the plate thickness in a region where an eddy current is liable to be generated in increased. The thickness of the low electric resistance material layer may not be increased but material having low resistivity may be used.

摘要： PROBLEM TO BE SOLVED: To lower the generated electromagnetic force of a current collecting coil and restrain the vibration of an outer tank by mounting a current collecting coil at a position where electromagnetic force working on the ground coil side surface of the outer tank in the external direction becomes weak. SOLUTION: Four current collecting coils 311 to 314, 321 to 324, 331 to 334, 341 to 344 are mounted, respectively, at equal intervals for superconducting coils 11 to 14. If the disposing distance of the superconducting coils is L, a pitch (b) for disposing current collecting coils 30 is 1350 mm/4 = 337.5 mm. The pitch (b) becomes smaller than a pitch of 2/3 of the cycle of harmonic generated at the surface of an outer tank. With this constitution, a boundary between the current collecting coil is positioned near a boundary 26 between race track superconducting coils, and the perpendicular conductor of the current collecting coil 30 is not installed on the arc part of the superconducting coil where the outward electromagnetic force of the outer tank is maximum, thus it is possible to lower outward electromagnetic force working on the current collecting coil 30.

As a result, a superconducting magnet for magnetic levitation railway use, which contributes to the enhancement of the current collecting power of a current collecting coil, is high in rigidity, is high in strength, is lightweight and has also a high magnetic field shielding effect, can be provided.

SOLUTION: Plate type anode conductors 9a, 10a and cathode conductors 9b, 10b are allocated in the upper and lower sides of a plurality of capacitor elements arranged. An insulating layer 12 is inserted between the anode conductors and cathode conductors. Lead wire of each capacitor element connects plate type conductors so that polarity is inverted from that of the adjacent capacitor element. For example, the anode lead wire 6a of the capacitor element 5 is connected to the anode conductor 9a passing through the cathode conductor 9b and insulating layer 12. Moreover, the cathode lead wire 6b is connected only to the cathode conductor 10b, and a hole 11 is opened between the anode conductor 10a and the insulating layer 12. Meanwhile, each lead wire of the capacitor element 7 is connected to the anode conductor 10a and cathode conductor 9b to provide the polarity inverted from that of the capacitor element 1.
