description: This work is devoted to the study of the breaking capacity of a high-voltage switch and the modernization of an arc extinguishing device to meet environmental requirements for switches. Tasks solved in the work: 1. Analysis of current models of high-voltage switches for the selected voltage class 2. Investigation of the interaction of the 330 kV 31.5 kA switch with the network 3. The study of a mathematical model for analyzing the pressure dynamics in the compression chamber of the arc extinguishing device, the choice of the empirical coefficient of the model. 4. Comparative analysis of the breaking capacity of an autocompression arc extinguishing device with SF6 and CO2. The empirical coefficient of the mathematical model is determined based on the agreement of calculation and experiment, its dependence on the cut-off current is shown. The breaking capacity of a high-voltage switch for two insulating gases is analyzed, the principal possibility of modifying the arc extinguishing device by replacing the working gas is shown, and recommendations are formed to increase the breaking capacity of an arc extinguishing device with CO2 insulation.
