Study and optimization of electromagnetic field in a vacuum interrupter

This paper presents the study of a vacuum interrupter (VI) of 12kV, in terms of optimization of the electrical field in order to obtain a more uniform distribution inside the VI chamber. The proposed method consists in combining the construction and simulation programs in a Solid Works module, respectively ComsolMultiphisics, with the optimization module that includes the programming environment Matlab and NSGA-II optimization algorithm. The robustness and the feasibility of this approach is supported by results that are comparable with the data available in the specialty literature.
