<p>PROBLEM TO BE SOLVED: To provide a superconducting transformer attached with a current- limiting device, which is compact, low in impedance voltage and can realize high voltage and large capacity. SOLUTION: A superconducting transformer 2, provided with a winding 4 formed of superconducting wire of which impedance voltage is set low, is connected with a superconducting current-limiting device 5 through a series connecting of the winding thereto, and the transformer 2 and device 5 are housed in a same vessel 1 filled with liquid helium. Then a short-circuit current is suppressed by the device 5, so as to result in a higher voltage and larger capacity for the transformer.</p> |
