ABSTRACT:
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.
