摘　　要：随着交直流电网规模的不断增长,纯电阻型超导限流器已经难以满足其限流需求。为了减少超导带材的用量并提高电阻型超导限流器的经济性,通过引入空芯分裂电抗器,研究了一种分裂电抗型超导限流器（DRSFCL）并对其基本限流原理进行了分析。通过建模和仿真研究,主要分析了DRSFCL在10 k V电压下的交直流限流特性,得到其在交流冲击下可有效地限制短路电流的第一波峰值,限流作用比较明显,且在直流冲击下也有较好的限流作用。最后通过直流冲击平台对部分直流仿真结果进行了试验验证,试验结果与仿真结果基本一致。With the development of AC and DC power grids, the pure resistive type superconducting fault current limiter（RSFCL） is hard to meet the demands of current limiting. In order to reduce the amount of superconducting tapes and improve the economy of the RSFCL, a novel divisive reactance type superconducting fault current limiter（DRSFCL） is investigated by introducing the air core divisive reactance, and the basic current limiting principle is analyzed. Through theoretically modeling and simulating, the current limiting characteristics of AC/DC under 10 k V voltage are studied. The results show that the first peak value of the short circuit current can well be limited under the AC short-circuit impact, and the current limiting effect is obvious. The current limiting effect is also good under the DC short-circuit impact. Some DC simulation results are verified by the DC impact platform, and the results are in agreement with the simulation results.
