The applications of anisotropic electrodes in vacuum circuit breakers to increase the switching life
KSPEU, Chair: Electrical power systems and grids, 420066 Russia, Kazan, Str. Krasnoselskaya, 51
The article analyzes the disadvantages of the vacuum circuit breaker, the transients that occur during switching, as well as the processes that lead to a decrease in the contact system resource. The simulation of the vacuum circuit breaker electrodes was performed using the COMSOL Multiphysics software package. The possibility of increasing the energy characteristics of vacuum circuit breakers by using single-crystal electrodes of copper, nickel, and iron as overlays is shown. A contact device for a vacuum circuit breaker with arc-resistant pads made of anisotropic materials has been developed.
