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.
