Description
Summary: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.
