description: The subject of the graduate qualification work is Â«Modernization of 10 kV, 40 kA SF6 circuit breaker for switchgearÂ». The given work is devoted to considering construction of a rotating arc chamber of an alternating current switch at a voltage of 10 kV, 40 kA using a magnetic blast. The research set the following goals: 1. Studying of SF6 circuit breakers with magnetic blast for medium voltage classes 6 - 35 kV, 31.5 - 40 kA for switchgear. 2. Analysis of the requirements of the power system to the circuit breaker 10 kV, 40 kA. 3. Calculation and development of a mathematical model of a rotating arc chamber in a SF6 circuit breaker 10 kV, 40 kA. 4. Modeling of the magnetic field for the magnetic blast system of the SF6 circuit breaker 10 kV, 40 kA. 5. Calculation of the elements of the pneumatic drive of the SF6 circuit breaker 10 kV, 40 kA. The analysis was conducted by the method of mathematical modeling with the use of Mathcad 15 and ELCUT. The results of a calculation experiment of the model of the arc chamber device are presented. The results of modeling the magnetic field for the magnetic blast system are analyzed and presented. The results of calculation of the pneumatic actuator and its control system are shown.
