description: Tasks solved in the course of the work: 1. Study of the interaction of the 220 kV, 31.5 kA circuit breaker with the electric grid. 2. Study the mathematical models describing of the parameters of the arc extinguishing in the arc-quenching chamber in the process of thermal breaking. 3. Modernization of the arc-quenching chamber. 4. Make a comparative analysis of the process of restoring t the electrical strength of the contact gap in a modernized and non-modernized arc-quenching chamber. In the work, calculations were carried out to determine the dynamics of the pressure in the compression chamber, under various operating modes of the high-voltage switch, when using an non-modernized and modernized arc-extinguishing device. The analysis was carried out by the method of mathematical modeling based on the solutions of the equations of magnetic gas dynamics (MGD) equipped with databases of the necessary thermodynamic parameters. The interaction of the high-voltage switch in different modes of shutdown with the electric grid was studied, the influence of the delay in opening the metal nozzle on the breaking capacity of the arcing device was analyzed. The possibility of increasing the breaking capacity without increasing the nominal pressure in a high-voltage switch with CO2 is shown.
