description: This work is devoted to the study of electrodynamic resistance of 20 KV switchgear busbars against short-circuit currents. Tasks that were solved during the research: 1. The study of classification and structure of 20 KV switchgears. 2. The study of Omega series of switchgears. 3. Creating 3D model of current-carrying systems of the busbar compartment for the switchgear cells in the Solidworks program. 4. The creation of 4 mathematical models for the electrodynamic processes in the current-carrying systems of switchgear in the Comsol multiphysics program, depending of the rounding of busbars, the presence of isolators in the meddle cabinet, ( importing the geometry, adding materials, adding limiting conditions, creating a mesh ). 5. Running the simulation for each one of the four models under the condition of short circuit currents flowing through the main parts of the busbars and checking the deformation which arises from the impact of electrodynamic forces of short circuit current on the busbars. At the end of this work, the maximum stress on the busbars was calculated in accordance with GOST, which made it possible to compare the obtained values from both modeling and calculation with the permissible ones, as well as to see whether the four models correspond to the permissible values specified in regulatory documents or not, and draw the necessary conclusions.
