description: This work is devoted to modeling and mathematical calculation of a real switch, the elements of which were provided. Tasks that were solved during the study:Overview of existing 220 kV high-voltage circuit breakers and the principles of their operation.Creating a 3D model of the device in the SolidWorks.Transfer and simplify the created model in the Comsol. Development of a mathematical model of the thermal state of the switch.The simplifications necessary to optimize the modeling process have been made.The calculation model was implemented in the COMSOL Multiphysics software, due to the internal interfaces of the program.The obtained simulation results made it possible to analyze some physical processes occurring during the flow of rated current and short-circuit current in the remote control of the switch of the Siemens 3AP DT model. Namely, a graph of changes in the electrical potential, current density, temperature changes and electrical tension in the conductive elements of the device.
