description: This work is devoted to the study of a contact system of the "tulip" type for use in 6-35 kV switchgear cells with a rated current of up to 2000 A. The study is aimed at studying the transient resistance of the contact system and the maximum temperature during the long-term flow of the rated current. Tasks that were solved during the study: 1. Construction of a geometric model of a plate model of a contact system of the "tulip" type. 2. Modeling of mechanical interactions to determine the contact pressure. 3. Calculation of the steady-state electric thermal regime in the contact system using numerical modeling methods. 4. Determination of the maximum permissible rated current. 5. Simulation of the shape of the short-circuit current curve with a duration of 3 seconds. 6. Calculation of the heating of the contact system when a short-circuit current flows. The work was carried out using the software of SolidWorks, COMSOL Multiphysics, MATLAB. In the SolidWorks environment, the calculated geometry of the contact was built, in the COMSOL Multiphysics environment, a multiphysical model of the contact system was created to study the electrothermal parameters under various operating modes of the contact system. As a result, the capabilities of the contact system were evaluated for the maximum rated current and resistance to short-circuit current. According to the results of the simulation, the contact system was able to operate with a rated current of 2000 A and withstand a short-circuit current of 40 kA.
