6.6㎸/200A급 DC 리액터헝 초전도한류기의 단시간운전 및 단락시험
Short-term Run and Short-circuit Test of 6.6㎸/200A DC reactor Type Superconducting Fault Current Limiter
초록
6.6㎸rms/200Arms DC reactor type superconducting fault current limiter (SFCL) has been developed. This paper deals with the manufacture and short-circuit test of the SFCL. DC reactor was the HTS solenoid coil whose inductance was 84mH. AC/DC power converter was performed as the dual-mode operation. The short-term run(1 sec) and short-circuit test of this SFCL was performed successfully. The experimental results have a similar tendency to the simulation results. In short-circuit test, at 2 cycles after the fault, fault current limitation rate was about 30%.
