Zusammenfassung:The present invention proposes a core structure applied to an SI-SFCL, which can minimize a core loss and is easy to assemble and easy to manufacture. The core structure of the present invention is a core structure of an SI-SFCL used in a DC power system, wherein first to fourth core units in which a plurality of unit cores are stacked are provided, and the structure is formed in a closed core type by the combination of the first to fourth core units. In addition, the cross-section of the first to fourth core units is designed to be circular. In the unit cores constituting the core unit, the length of the unit core disposed in the center is the longest, and the length of the unit cores disposed in left and right directions is gradually shortened, so that the cross section of the first to fourth core units is circular. 본 발명은 철심 손실을 최소화시키면서 조립이 쉽고 제조가 용이한 초전도 한류기에 적용되는 철심구조체를 제안한다. 본 발명의 철심 구조체는, DC 전력시스템에 사용되는 포화 철심 초전도 한류기(SI-SFCL)의 철심 구조체로서, 복수 개의 단위 철심이 적층 형성되는 제1 내지 제4 철심유닛이 제공되며, 제1 내지 제4 철심유닛들의 결합에 의해 폐심형(closed core type)으로 형성된다. 그리고 상기 제1 내지 제4 철심유닛의 단면은 원형이 되도록 설계된다. 상기 제1 내지 제4 철심유닛의 단면이 원형이 되도록 철심유닛을 구성하는 단위 철심들은, 중앙에 배치된 단위 철심의 길이가 가장 길고, 좌우측 방향으로 배치되는 단위 철심들의 길이는 점점 짧아지게 형성된다.
