Abstract
Method and equipment for transferring energy to or from a direct-current superconducting field coil to change the magnetic field generated by the coil in which a second direct-current superconducting coil is used as a storage coil, and energy transfer between the field coil and the storage coil is effected automatically in dependence upon a control programe. Preferably, the control programe acts upon a variable transformer which is coupled by respective rectifier/inverters to the field and storage coils and also serves for initial supply of energy to the coils.
Claims12
Equipment for transferring energy to or from a direct-current superconducting field coil to change the magnetic field produced by the coil, said equipment comprising a storage coil which is a direct-current superconducting coil generating a magnetic field when energized, energy transfer means interconnecting said field coil and said storage coil, said energy transfer means being electrically controllable to initiate energy transfer between said field coil and said storage coil in either direction and to control the rate of such energy transfer, and electrical control means connected to said transfer means for the electrical control thereof in accordance with a predetermined program whereby to effect a desired transfer of energy between said coils.
