A superconducting transformer was designed for the correction coils (CC) conductortest facility in the Institute of Plasma Physics, the Chinese Academy of Sciences (ASIPP), forvalidating the CC conductor of the international thermonuclear experimental reactor (ITER).The maximum current of the superconducting transformer is 50 kA. The conductor samples couldbe tested at different magnetic fields and cooling conditions similar to the operational conditionof ITER. During normal operation, the primary and secondary windings of the superconductingtransformer will withstand the high electromagnetic (EM) stress caused by the high current.Integrated analysis of EM and structural fields can ensure these components not to encounter anyover-stress problem under normal operational condition. A coupled model is proposed to combinethe EM and structural analyses. A detailed finite element (FE) model and EM-structural coupledmodel are presented and the numerical results show that the stress of the transformer windings iswithin the allowable limits.
