Logan, J R

This patent describes a modular superconducting magnetic energy storage inductor apparatus. It comprises an annular dewar structure oriented in a substantially horizontal plane and containing a cryogenic fluid; a plurality of winding modules each comprising a multilayer, layer wound winding of superconducting material, the winding modules staked one on top of another in the annular dewar and immersed in the cryogenic fluid; means interconnecting the plurality of winding modules in at least one electrical circuit; and shorting switch means comprising for each winding module a single shorting switch connected across the winding of the winding module and selectively shorting the winding during an emergency dump of the cryogenic fluid from the dewar.
