Modeling of metallized film capacitors segmented electrodes electrodynamic destruction

electrodynamic destruction due to electrothermal evaporation of segmented zinc electrodes used in metallized film capacitors was experimentally studied. Numerical model of segmented electrodes electrothermal evaporation was developed using COMSOL Multiphysics software. This model takes into account all necessary electrical and thermal material’s parameters. The results of simulation are in good agreement with experimental data. Numerical model can be used for optimization of segmented electrodes parameters and checking its efficiency.
