Rapid fusing type current limiter

The invention relates to a rapid fusing type current limiter, which is characterized by comprising a rapid mechanical switch connected in series on a main path, a fuse connected in parallel on the rapid mechanical switch, and an arc extinguishing device used for extinguishing electric arcs between fractures of the rapid mechanical switch, when a short-circuit fault occurs, the rapid mechanical switch on the main path is switched off, the arc extinguishing device starts arc extinguishing, and after the short-circuit current is transferred to the fuse, the fuse is fused to dissipate the short-circuit current. A current limiter model is constructed, and a controllable voltage source is adopted in the current limiter model to simulate the fusing process of a fuse. The fault current transfer process of the current limiter is simplified, the fault current transfer and current limiting speed is high, and the on-off reliability is high. 本发明涉及一种快速熔断式限流器，其特征在于，包括用于串联在主通路上的快速机械开关、在快速机械开关上并联的熔断器和用于熄灭快速机械开关断口间电弧的灭弧装置；当发生短
