摘　　要：针对系统发生短路故障时迅速产生的短路电流,设计了一种由新型电磁斥力机构、固态开关和ZnO避雷器组成的新型故障限流器。在Ansoft软件中搭建了电磁斥力机构和永磁机构在瞬态场下的仿真模型,对分、合闸过程中的磁场、位移以及速度随时间的变化情况进行了仿真分析,并分别对固态开关和ZnO避雷器在故障限流器中的作用以及应用条件进行了阐述,证明了此类新型故障限流器能够在系统中起到很好地限制短路电流的作用。Aiming at short circuit current generated quickly on system taking place with short circuit fault, this paper designed a new type of fault current limiter consisting of electromagnetic repulsion mechanism, solid switches and ZnO arresters, and established the simulation mode of electromagnetic repulsion mechanism and permanent magnetic mechanism under instant ifeld in Ansoft software, carrying out simulation study for magnetic ifeld, displacement and change situation of speed following time in making and breaking processes. Description was respectively made to functions and application conditions of solid switches and ZnO arresters in fault current limiter, which proves that this kind of new type fault current limiter can play a good function to limit short circuit in the system.
