More Information
Summary:The disclosure relates to a mechatronic circuit-breaker device adapted to break an electrical current flowing through electrical power transmission means, the device including a main branch comprising at least one electromechanical switch-disconnector connected in series with at least one breaker cell itself electrically in parallel with a snubber and a first voltage surge limiter; an auxiliary branch electrically in parallel with the main branch and comprising at least one power electronic switch, connected in series with at least one capacitor, itself electrically in parallel with its discharge resistance and a second voltage surge limiter, The first voltage surge limiter has a sharper voltage-current characteristic and offering a much steeper slope at low currents than the second surge limiter.
