description: This work is devoted to the calculation of the thermal conditions of metal film capacitors of domestic and foreign production under various operating modes, both the nominal operating mode specified in the manufacturers passports and the maximum permissible for restrictions on the types of dielectric materials. The purpose of this work was to study various cooling conditions at temperature conditions of metal film capacitors under sinusoidal voltage conditions. Geometric models of capacitors were developed in the COMSOL Multiphysical environment: two capacitors of JSC ELKOD K73-50 (polyethylene terephthalate) and K78-37 (polypropylene), as well as a capacitor MKT1813 of the American company Vishay Intertechnology. In addition, the resistance of the contact nodes of the metal film capacitor and, accordingly, with respect to the dielectric constant and dielectric loss tangent from frequency and temperature were prevented. Next, using the tools of the COMSOL Multiphysics environment, stationary thermal problems were solved and graphs of the temperature distribution in the capacitors were obtained. After this, similar calculations were carried out with different cooling conditions.
