More Information
Summary:According to the present invention, a saturated iron core type superconducting fault current limiter for a direct current (DC) power system may comprise: an iron core as a magnetic field flow path; a primary coil positioned on the primary side of the iron core and forming a DC power supply path in a DC system; a secondary coil positioned on the secondary side of the iron core and having a superconducting wire wound thereon; a DC power supply for supplying a default DC current to the secondary coil; and a power consuming element connected in parallel with the DC power supply. The power consuming element may be formed of a metal oxide arrester (MOA). 본 발명의 포화철심형 직류용 초전도 한류기는, 자기장 흐름 경로가 되는 철심; 상기 철심의 1차측에 위치하며, 직류 계통상에서 직류 전력의 공급 경로를 형성하는 1차측 코일; 상기 철심의 2차측에 위치하며, 초전도 선재가 감겨진 2차측 코일; 상기 2차측 코일에 디폴트 직류 전류를 공급하는 직류 전원; 및 상기 직류 전원과 병렬 연결된 전력 소모 소자를 포함할 수 있다. 여기서, 상기 전력 소모 소자는, MOA(Metal Oxide Arrester)로 구성될 수 있다.
