description: The work is devoted to the development of mathematical model for evaluating the breaking capacity of an extinguishing device 330kV, 50kA. Tasks solved in the course of the work: 1. Study of parameters affecting on the breaking capacity of modern high-voltage gas circuit-breakers with auto-puffer arc-quenching chamber. 2. The study of mathematical models describing the parameters of the switching arc in the arc-quenching chamber and the formation of a mathematical model for the analysis of the breaking capacity, taking into account the influence of turbolization of the arc extinguishing flow. 3. Analysis of the choice of turbulence model for breaking capacity in the thermal phase of breakdown. 4. Evaluation of the breaking capacity in the arc-quenching chamber at different levels of turbulent intensity of the arc extinguishing flow. The paper analyzes modern gas circuit-breakers with various arc extinguishing media. The interaction of a 330 kV, 50kA circuit-breaker with the grid is investigated. The analysis of modern approaches to modeling turbulence in the switching arc is carried out. On the basis of the MHD equations, numerical experiments were carried out to assess the effect of the level of turbulence on the processes occurring in the switching arc. It is shown that the level of turbulence of the arc-extinguishing flow affects the breaking capacity in a 330kV, 50kA high-voltage switch with an circuit-breakers with auto-puffer arc-quenching chamber with CO2 insulation.
