description: The subject of the graduate qualification work is Â«Modernization of the arc-suppression system of switch-disconnector VR32-31A 30220 100A TDMÂ» The work is devoted to numerical simulation of VR32 low-voltage breaker switching. The model is built using real geometry of VR32-31A 30220-00 breaker and arc chutes. The geometry of the contact part of the circuit breaker and the stages of building the model are presented in the work. Description of the mathematical model with an indication of the initial and boundary conditions is presented in the work. Fundamental laws of physics are the basis of the model and describe physical processes in the form of partial differential equations. Thus, the arc extinguishing process in the breaker is a multiphysics task: system of Maxwell's equations, heat balance and momentum equations. The model includes a description of the breaker contact movement of using a moving mesh. Modeling of the switch-disconnector was performed in the COMSOL Multiphysics software package, and the modified model of the switch-disconnector was simulated there as well.
