Abstract The effect of different parameters on the electro-magnetic repulsion mechanism is analyzed in order to design an effective high speed contact mechanism. The mathematical model of the electro-magnetic repulsion mechanism is established and finite elements simulation software is used to calculate the repulsion force of the electro-magnetic repulsion mechanism. Simulation results show the effect of different parameters on the electro-magnetic repulsion mechanism. A high speed contact mechanism is designed for DC320V/3kA hybrid switch. Experimental results show that the mechanism is able to separate within 220μs. It meets the demand of hybrid switch for high reaction speed and high motion speed.

Key words： High speed mechanical contact electro-magnetic repulsion mechanism finite elements simulation hybrid current limiting circuit breaker
