description: Theme of the final qualification work: "Calculation of the thermal state of the current-carrying parts of the switchgear 10kV, 4000A". The purpose of this final qualifying work is to study the properties and operation of complete switchgears, the construction and calculation of the currentcarrying system of the cell. The subject of this final qualification work is a complete switchgear of the VOLGA series. In this study, the priorities are: 1. The study of the essence and functioning of complete switchgears. 2. The study of KRU series VOLGA. 3. Creating a model of the current-carrying system and comparing two busbar sections. 4. Presentation and comparison of simulation results. Mathematical modeling of the heating process of copper contact joints of two different sections of a complete switchgear of the VOLGA series was carried out. A mathematical model has been created that allows heating to compare the set temperature with the standard values. The results of numerical simulation are presented. The practical result of this final qualifying work was the development of an effective model of current-carrying copper bars. Air complete switchgear (KRU) 10 kV, 4000 A of the VOLGA series type with a cross section at which the temperature does not exceed the permissible value.
