description: The theme of the final qualifying work: "Electrodynamic impact of short-circuit currents on busbars MCS6 (10) kV, 50 kA".This work is devoted to the study of 6(10) kV switchgear busbars for electrodynamic resistance against short-circuit currents.Tasks that were solved during the study:1. Classify MCS. Studying the design of switchgear 6 (10) kV. Analysis of regulatory documents.2. Creation of a three-dimensional model of the busbar compartment of the switchgear cell in the SolidWorks environment, description of the model.3. Creation of a mathematical model of the current-carrying system of switchgear in the nominal mode of operation. Description of the mathematical model of the processes of the current-carrying system of switchgear4. Creation of a mathematical model of the operation of the current-carrying system of the switchgear in the short circuit mode. Description of the mathematical model of the processes of the current-carrying system of switchgear5. Calculation of electrodynamic forces in a current-carrying contact system in short circuit mode.In the course of this work, a geometric model of the contact connection of the 6 (10) kV switchgear busbars was developed. On its basis, modeling of electrodynamic processes in the busbar assembly compartment was carried out with the passage of rated current and short-circuit current.The results of the calculation of electrodynamic processes in the busbar compartment made it possible to compare the obtained values of the forces that act on various elements with the permissible ones, guided by regulatory documents.
