We research team has proposed a current-limiting superconducting DC circuit breaker that combines a High-temperature superconducting wire (HTS) with a DC circuit breaker, and secured its operation performance in our previous study via simulation. In this paper, we designed and produced an actual current-limiting superconducting DC circuit breaker, as well as analyzed its current limiting and breaking performance. In addition, the operation characteristics at different lengths of the HTS with increasing voltage were analyzed. The operation reliability of the proposed DC circuit breaker was demonstrated by a simulation system that was built similar to the actual system.

超导线圈应用于换流电路的限流直流断路器的特性

我们的研究团队提出了一种限流超导直流断路器，该断路器将高温超导线 (HTS) 与直流断路器相结合，并在我们之前的研究中通过仿真确保了其操作性能。在本文中，我们设计并制作了一个实际的限流超导直流断路器，并分析了其限流和开断性能。此外，还分析了不同长度的高温超导电压随电压增加的运行特性。所提出的直流断路器的运行可靠性通过一个与实际系统相似的仿真系统来证明。
