    摘要： A superconducting magnet abnormality detection and protection apparatus is for early and surely detecting abnormality in superconducting coils mounted on a vehicle and protecting the superconducting coils. Magnetic flux detecting devices are mounted inside an outer vessel, which is a vacuum container of a superconducting magnet, so as to be opposite to the superconducting coil. Voltages induced in the magnetic flux detecting devices are detected. Voltage signals are led to a decision device. By monitoring the change of the voltage signals with time in a comparing judgment device, it is determined whether there is an abnormality. If there is an abnormality, an alarm indicator informs of an abnormal state, and a protection device takes protection measures such as interruption of the current of the superconducting magnet. Owing to such configuration, heat does not penetrate from the outside into the superconducting coil via instrumentation lead wires of the magnetic flux detecting devices. Magnitudes of vibration and displacement of the superconducting coil can be detected without contacting the superconducting coil. By always monitoring these signals, it becomes possible to early detect an abnormality in the superconducting coil and protect it.

    摘要： A superconducting energy storage device for storing electric power in superconducting magnets in the form of magnetic energy. The superconducting magnets are include a superconducting toroidal magnet and a superconducting solenoid magnet arranged to be inscribed in the inside of the superconducting toroidal magnet, the magnets being connected electrically in series to each other. Further, the superconducting magnets include a plurality of units, each of which is formed as a combination of the aforementioned toroidal and solenoid superconducting magnets, the units being piled up in the axial direction of the superconducting solenoid magnet. In the thus arranged device, electromagnetic force generated in the superconducting magnets can be supported without the necessity of firm bed rock, thereby eliminating the limitation in conditions of location of the energy storage device. Further, the plurality of energy storage units can be arranged effectively so that space can be saved.

    摘要： A beam member which is installed at diametral portion in a ring shape superconducting coil container for supporting hoop stress of the coil, or a portion of radiant heat shield covering the beam member, is partly or entirely composed of electrical insulators or high resistivity materials. In accordance with the above composition, eddy current which is generated in the coil container when the superconducting coil container crosses magnetic field caused by eddy current which is generated in the radiant heat shield when the radiant heat shield crosses strong magnetic field caused by the superconducting coils with relative vibration of the radiant heat shield to the superconducting coil by a dynamic cause can be suppressed. Accordingly, heat generation in the superconducting coil container can be reduced, and consequently, generation of quenching can be prevented.

    摘要： There is disclosed a coil structure which can be rapidly energized or excited, and which reduces the generation of heat in a coil container by an eddy current due to a dynamic disturbance such as vibration and a magnetic field fluctuation, thereby suppressing the occurrence a quench. The coil container is constituted by a low-resistivity material, and a high-resistivity portion is provided at at least one portion of the coil container in the direction of the periphery of the coil container. The high-resistivity portion is provided at a position where a vibration displacement is small or a magnetic field fluctuation is small. When the coil structure is to be energized or excited, the eddy current produced in the direction of the periphery of the superconducting-coil container can be reduced at the high-resistivity portion, and when the dynamic disturbance develops, the generation of heat by the eddy current is suppressed by the low-resistivity material.
