description: This work is devoted to the development of a contact cooling system of a vacuum circuit breaker. Tasks that were solved during the study: 1) Study of the features of the vacuum circuit breaker model. 2) Creation of models of the contact system of the vacuum circuit breaker and the cooling radiator. 3) Performing calculations of models of thermal processes in a vacuum circuit breaker using the COMSOL Multiphysics cross-platform software. Â  Â  In this work, the influence of the geometric parameters of the cooling radiator, in particular the shape and height of its ribs, on the temperature of the entire contact system was determined. A model was chosen for more efficient cooling of the contacts of the vacuum arcing chamber. Â  Â  The thermal mode of a mathematical model of a vacuum circuit breaker was investigated. As a result, thermal processes were simulated in a vacuum arc extinguishing chamber and in external cooling radiators. Â  Â  The simulation was carried out using the COMSOL Multiphysics cross-platform software adapted for finite element analysis. The results were also obtained at different heights of the radiator fin, a graph of the temperature dependence on the current terminals on the wall height was plotted.
