  • Self-expansion electrical circuit breaker with variable extinguishing chamber volume
    Patent number: 4950855
    Abstract: A self-expansion electrical circuit breaker includes an arc extinguishing chamber of variable volume by repulsion of a piston by the pressure of the gas in the extinguishing chamber. A semi-stationary contact is securedly united to the piston so as to increase the separation distance of the contacts at the same time as the volume of the extinguishing chamber increases.

  • Puffer type electrical circuit breaker having a high dielectric withstand
    Patent number: 4736079
    Abstract: The invention relates to improving the dielectric withstand of a puffer circuit breaker having a main circuit arranged side by side with an arcing circuit inside a sealed insulating casing filled with an insulating gas SF6.The disconnection area arranged between the main contacts when the main circuit opens is located facing the breaking gap between the arcing contacts. The fixed main contact and the fixed arcing contact are at the potential of the upper terminal, being located at appreciably the same level on either side of the longitudinal axis of the casing.
