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. 1. Study of the device, models and types of switchgear for a voltage value of 35 kV. Standardization, certification, and analysis of regulatory documents describing the operation of such devices. 2. Creating a three-dimensional model of the busbar compartment of the CRU cell. Made in the computer-aided design system "SOLIDWORKS 2018". 3. Development of a mathematical model of electromagnetic and thermal processes in the bus compartment of the CRU cell, description of the mathematical model. Working and setting boundary conditions with the created model in the COMSOL Multiphysics platform: selection of system-forming materials and physical modules, their configuration.
