description: The topic of the graduation work: "Modernization of the HV extinguish camber with heating volume 220 kV, 40 kA, CO2". In the work, the parameters affecting the breaking capacity of the arc extinguishing device are investigated, and the modernization of the 220kV, 40kA arc extinguishing device is carried out. Tasks solved in the work: 1. Study of mathematical models describing the parameters of the shutdown arc in arc extinguishing devices of various types during shutdown. 2. Design and modernization of the flow part of the arc extinguishing device. 3. Analysis of the breaking capacity of the upgraded arc extinguishing device with CO2 insulation while maintaining the breaking capacity at the selected nominal parameters. The main directions in the research of high-voltage switches are considered and the possibilities of using CO2 in them are analyzed. The analysis of existing 220kV, 40kA switches was performed and their interaction with the network was analyzed. The study of modern approaches to modeling wall ablation in gas high-voltage switches allowed us to formulate the direction of modernization of the arc extinguishing device. Based on mathematical models for calculating the breaking capacity of an auto-generating and auto-compression type arc extinguishing device, the analysis of the breaking capacity of a switch with various types of arc extinguishing devices and gases was carried out. An arc extinguishing device of 220 kV, 40 kA was designed and upgraded, an analysis of its shut-off ability when replacing the arc extinguishing gas was carried out.
