摘　　要：阐述了磁通约束型超导限流器的基本原理,仿真分析了限流器在系统中限流效果以及电流变化,解析计算了限流过程中的产生的冲击电流;针对400V/20A容量的磁通约束型超导限流器,分析了限流器限流过程的电压分布,对比在层绕与饼绕两种设计方案下电压分布的差异以及磁场分布变化。This paper expounded the basic principles of the flux constraint superconducting fault current limiter,analysed and simulated the current limiting effect of current limiter in the system and the change of current in transient process, calculated the impact of current in the process of the current limiting. It also analyzed the voltage distribution of current limiter capacity of 400V/20A during the process of current limiting and compared tbe difference of the voltage distribution and the change of magnetic field distribution between two design schemes which were layer - winding and pancake - winding of a flux constraint superconducting fault current limiter capacity.
