In the present paper, a theoretical model of the mobility for multidisperse particles is developed. The present model is the extension of the previous theoretical model and the semi-empirical model for the monodisperse partcles. This model includes the influence of particle size distributions and is suitable for all particles with different materials and with different size distributions.

Under the base of it, also considering the characteristics of the multi-channel multistage rimfire gas switch, much study and experiments of the surface flashover along the PMMA insulator and the PMMA housing of the switch were done. Following conclusions were drawn: After introducing PMMA insulator among the board electrodes, the voltage of the discharging of the SF6 drops by 30%. With increasing of the pressure of SF6, voltage of the discharging descends more sharply. With PMMA spacer, the dispersing of the discharging voltage of the gas gap increased as compares to the unbridged gap, such increases in value of the discharging voltage become more obvious with the gas pressure increased.
