Was build the mathematical model, that takes into consideration the parameters of arc extinguishing camera. As the most important parameters were taken such ones on what the target-orient function depends much, i.e. the derivatives of these parameters are relatively great. Was revealed out that the size of the voltage of the arc is influenced by the geometrical dimensions of the arc extinguishing grill as well as by the parameters of the arc and gas kinematical ones. As basic parameters of optimization of arc extinguishing grill were taken: the numbers of plates of the grill – n; the distance between the plates of the grill – b. As the third basic parameter of the arc extinguishing chamber was solved the volume of the air in it, then the thickness of the grill’s plates becomes the function of the chosen optimization parameters. The maximal value of the pressure in the chamber Pm is one of the restrictions toward the area of allowed values. Having chosen so the controllable values (r, b, V) and the restriction, was formulated the problem of arc extinguishing chamber’s parameters optimization.
