description: Theme of final qualification work: âStudy of the breaking capacity of a 35 kV-31.5 kA/2000 A vacuum circuit breaker with an axial magnetic fieldâ.This work is devoted to the study, development and analysis of the breaking capacity of vacuum circuit breakers for various geometries. Tasks to be solved in the course of the study:Preliminary selection of materials and dimensions of the construction of the arc chuteAnalysis of the interaction of the vacuum circuit breaker with the network, in particular, the analysis of the nominal parameters and the transient recovery voltage during a short circuitCarrying out calculations of models of electromagnetic processes in a vacuum arc chute, in order to assess the breaking capacityAs a result, electromagnetic processes were simulated in a vacuum interrupter chamber and the axial component of magnetic induction was calculated to determine the breaking capacity. The simulation was carried out using the crossplatform software COMSOL Multiphysics, adapted for analysis by the finite element method.Â In this paper, we carried out a comparative analysis of vacuum and gas-insulated circuit breakers. The dependence of the arcing stability and current sealing on the contact material and the influence of the contact geometry on the axial magnetic field are analyzed. The nominal parameters of the vacuum circuit breaker were selected and the normalized parameters of the HPV were calculated. A mathematical model of processes occurring in a vacuum arc chute has been studied.As a result, modeling of electromagnetic processes in a vacuum chamber and calculation of the axial component of magnetic induction were carried out to determine the breaking capacity. Simulation is COMSOL Multiphysics Multiplatform Finite Element Analysis Software.
