DC REACTOR HAVING BOBBIN EQUIPPED WITH SUPPLEMENTARY WINDING FOR UNIFORMLY DISTRIBUTING FAULT CURRENT TO SUPER CONDUCTOR TAPE

摘要

PURPOSE: A DC reactor is provided to allow current to flow through a supplementary winding upon occurrence of fault current, by arranging the supplementary winding to prevent the fault current from concentrating on the inside of a super conductor tape. CONSTITUTION: A DC reactor comprises a phase conduction supplementary winding for uniformly distributing fault current to a super conductor tape laminated on a bobbin, upon occurrence of fault current. The phase conduction supplementary winding is arranged at the outermost part of the bobbin. The super conductor tape is laminated together with the phase conduction winding.
