Abstract Zero-current breaking technology is an important content in the research of intelligent AC contactor. In this paper, the optimization calculation aimed to breaking quickly of the electromagnetic mechanism of the intelligent AC contactor is conducted, by using the ANSYS electromagnetic software and the artificial fish swarm optimization algorithm based on genetic algorithm. This method not only ensures the reliable contact process of the intelligent AC contactor, but also realizes a quick release of the executive mechanism, thus greatly reduces the influence to the stability and accuracy of the three-phase contactors, especially the first opening phase when zero-current breaking, which improves the reliability of zero-current breaking and increases the technology research level of the intelligent AC contactor. A prototype is made based on the results of the optimization designation. The testing results show that the breaking time of the intelligent AC contactor is shortened greatly, and the stability of the breaking time is improved significantly too, so the reliability of the zero-current breaking increases significantly.

Key words： AC contactor intelligent technology zero-current breaking genetic algorithm artificial fish swarm algorithm ANSYS software
