10kVA High $T_c$ Superconducting Power Transformer with Double Pancake Winding

더블펜케익 권선형 10kVA 고온초전도 변압기

This paper presents the design of a double pancake winding type high $T_c$ superconducting power transformer In the design of the transformer. BSCCO-2223 tape was considered as the conductor. Double pan cake winding was adopted in order to easy the construction of the winding and to lessen the leakage reactance of the transformer. Numerical calculation was used to decide the arrangement of the double pan cake winding. Room temperature bore type cryostat has been constructed and its heat loss was estimation.
