description: In this work, we developed a technique and calculated the heating of the current system of a switchgear cell with a busbar current of 1600 A and a voltage of 35 kV. The heating of the switchgear current system with current of 1600 A and a voltage of 35 kV calculated in this work. The model was created on the drawings of a similar switchgear cell from a Russian manufacturer, from which its overall dimensions and internal structure were obtained. The dimensions of the busbar system were determined experimentally. In the process of developing the methodology, the following goals were solved: 1. The study of the structure and classification of switchgear for this voltage class. Identification the main technical documents governing the operation of such devices. 2. Creation of a mathematical model in the system of three-dimensional modeling Â«COMPASÂ». 3. Work with the created model in the Â«COMSOL MultiphysicsÂ» platform: selection the necessary materials and physical modules, their adjustment, construction a calculation grid and processing the obtained data. 4. Conclusions based on simulation results. As a result of the work, a graphical display of heating of the busbar system was obtained, and losses on the heating of the conductors were calculated. The obtained parameters are compared for several cells connected to the same busbars. It is concluded that the cell meets the requirements of GOST according to the parameters studied, as well as the applicability of the developed methodology for solving real problems with a given accuracy.
