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
