    摘 要:針對系統發生短路故障時迅速產生的短路電流,設計了一種由新型電磁斥力機構、固態開關和ZnO 避雷器組成的新型故障限流器。在Ansoft 軟件中搭建了電磁斥力機構和永磁機構在瞬態場下的仿真模型,對分、合閘過程中的磁場、位移以及速度隨時間的變化情況進行了仿真分析,并分別對固態開關和ZnO 避雷器在故障限流器中的作用以及應用條件進行了闡述,證明了此類新型故障限流器能夠在系統中起到很好地限制短路電流的作用。
    關鍵詞:故障限流器;電磁斥力機構;固態開關;ZnO 避雷器

    Abstract: 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 field in Ansoft software, carrying out simulation study for magnetic field, 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.
               Key words: fault current limiter; electromagnetic repulsion mechanism; solid switch; ZnO arrester
