With an aim of development for new functions of superconducting electric power equipment, we proposed Superconducting Fault Current Limiting Transformer(SFCLT) and extended our research from both theoretical and experimental approach.1.Theoretical simulation of SECLT to introduce power system introduction effect of 500kV/275kV SFCLT into power system was simulated under the coudition of 3-phase short circuit. Phase angle characteristics, short-circuit current, high voltage and thermal characteristics were discussed and optimum paramenters were obtained.2.Experiment of model SFCLTAccording to the theoretical simulation results, 1 /1000 scale model SFCLT was designed and fabricated with 275 V/105V, 6.25kVA ratings. In addition, the experimental model was introduced into the Transient Network Analyzer and the conbined functions of SFCLT were confirmed. Through these theoretical and experimental discussions, we could have sufficient characteristics of SFCLT with both functinus of fault current supperession and system stability improvement.

为了开发超导电力设备的新功能，本文提出了超导故障限流变压器(SFCLT)，并从理论和实验两方面展开了研究。1.对超导限流变压器引入500KV/275KV超导限流变压器在三相短路情况下的电力系统引入效应进行了理论仿真。2.模型实验根据理论模拟结果，设计制作了额定电压为275V/105V、额定电压为6.25kVA的1/1000比例尺模型SFCLT。此外，将实验模型引入暂态网络分析仪，验证了SFCLT的组合功能。通过这些理论和实验的讨论，使SFCLT具有充分的抑制故障电流和提高系统稳定性的功能。
