description: In this work, a method for calculating the combustion electric arc in the switchgear K-318 NE with a current of 1250 A busbars and a voltage of 10 kV is developed. Using drawings in AutoCAD, which are provided by the company "Novaya ERA" (Application 1), a model of the cable compartment of the K-318 NE device was built in the SolidWorks program. Calculations of the distribution of the electric field strength and the trajectory of the air gap breakdown were carried out in the COMSOL Multiphysics software. In the process of developing the calculation method, the following tasks were solved: 1. Analysis of regulatory documents regulating the work of the switchgear. Consideration of the classification and design features of cells. 2. Building the model geometry in the CAD system "SolidWorks". 3. Performing the calculation in the program "COMSOL Multiphysics". In particular, the selection of materials and the configuration of physical interfaces, the creation of a calculated grid and the analysis of the results obtained. 4. Conclusions based on the simulation results. As a result, graphs of the distribution of the electric field strength and the trajectory of the breakdown of air gaps in the switchgear cell are obtained, and the probabilities of the breakdown are calculated. A new model is constructed, where there is no breakdown.
