Abstract

We have been studying a superconducting transformer for rolling stock. From the result of a design study for 25kV 4MVA supeconducting transformer, we have fabricated a secondary winding superconducting coil to investigate its performance. We used bi2223 superconducting wire for the coil. Furthermore, we have fabricated refrigeration test equipment, which is made up of a stainless still coil and a refrigerator including a heat exchanger and a pump to circulate liquid nitrogen.
