  • Hybrid circuit breaker device
    Patent number: 7508636
    Abstract: This invention relates to a circuit breaker device comprising a main branch (1) comprising a mechanical switch element (2) and an auxiliary branch (3) containing a semiconductor breaking cell (4), this auxiliary branch (3) being mounted in parallel with the main branch (1). The main branch (1) comprises a serial switching assistance module (M2) in series with the mechanical switch element (2), comprising a semiconductor breaking cell (5) controllable in opening in parallel with an impedance (Z1). The auxiliary branch (3) comprises a parallel switching assistance module (M4) comprising an impedance (Z2), this impedance (Z2) including at least one capacitor type element (C).
