Analysis of Quench Characteristics according to increment of turn number of a reactor and shunt resistors of the Matrix-type Superconductor Fault Current Limiter

매트릭스형 초전도 전류제한기의 리액터의 턴수 및 션트저항 증가에 따른 퀜치특성 분석

The matrix-type superconducting fault current limiter (SFCL) using YBCO thin film consists of the trigger and current-limiting parts. We fabricated the matrix-type SFCL with the integrated current limiting modules. we carried out the experiment of matrix-type SFCL with the integrated current limiting modules connected in series or parallel. We saw current characteristics due to ratio of change the shunt resistance and turns. We confirmed that the difference of critical current between superconducting units was decreased by increment of current flowing into the reactor which applied the magnetic field into the superconducting units..
