Abstract
A superconducting transformer comprises primary and secondary superconducting coils which are coaxial and made of superconducting wires, and a cryostat for maintaining the superconducting coils in a superconducting state. The cryostat includes a vessel for containing refrigerant and which is formed of a ferromagnetic material. The coils are immersed in the refrigerant. Rod formed of ferromagnetic materials is inserted in the primary and secondary superconducting coils, and is magnetically coupled with the vessel. The cryostat also includes a heat insulating tank for thermally insulating the rod and the vessel from the refrigerant. The rod and the vessel together form a closed magnetic circuit, and function as a core for the superconducting coils.
