摘　　要：围绕新型高温超导限流器(HighTemperatureSFCL)试验样机工程化,提出该限流器的改进拓扑方案———串电阻桥式高温超导限流器,分析其限流工作过程,并提出了优化设计目标。制作了220V/60A的试验装置,为10·5kV/1·5kA高温超导限流器的配电系统并网试验运行提供了理论和技术支持。Combined with the topology analysis of bridge type FCL for its fault current function, the transient state mathematical model for new type of high temperature superconducting fault current limiter with serial resistance is established. The optimization design goals, the relationship of the performance of HTSFCL and its parameters are proposed. Based on this, a 220V/60A SFCL system was developed and the theoretical predictions are validated by the experiment result, which lays a sound foundation for the 10.5kV/1.5kA HTSFCL system that is installed to a power grid in Hunan province.
