description: Theme of the final work: "Auto-generating SF6 arc extinguishing device 500kV, 63kA" In this paper, conclusions are drawn that affect the breaking capacity of a 500kV, 63kA SF6 gas-filled arc quenching device and the breaking capacity method due to a delay in the opening of a metal nozzle. Tasks solved in the course of work: 1. Study of the interaction of the circuit breaker 500kV, 63kA with the electric system 2. Description of the mathematical model of the change in parameters observed in the arcing consumption 3. Calculation of the geometrical parameters of the arcing device 4. Simulation of the upgraded auto-puffer with heating volume circuit breaker in COMSOL Multiphysics In the course of the work, modern circuit breakers 500kV, 63kA were investigated. The principles of operation, advantages and benefits of auto-puffer with heating volume arc extinguishing devices are analyzed. A study was made of the interaction of the 500kV, 63kA circuit breaker with the network. A modification of the selfgenerating arc extinguishing device is proposed and modeled. The analysis of the processes in the circuit breaker was carried out, cases of detection of Mach and pressure and various moments were revealed: opening of contacts, contact in the neck of the insulating nozzle, poisoning. The analysis was carried out by numerical simulation in the COMSOL Multiphysics software package based on gas dynamics solutions. Calculations affecting the breaking capacity have been carried out.
