Abstract (en)
[origin: WO2012011119A1] The invention relates to a pressure-propelled contact system for gas circuit breaker interrupter, comprising : an insulating chamber for storage of gas; a metallic blast cylinder having a movable piston for pressurizing the gas supplied from the insulating chamber; an insulating nozzle for blowing compressed gas over a high temperature arc when formed due to electrical fault between a pair of designated fixed contact means, and a moving arcing contact means; Characterized in that the designated fixed arcing contact is configured as movable due to a differential pressure generated during the current interruption process, in that a compression ring is provided to the fixed arcing contact to increase the relative speed between the fixed arcing contact and the moving arcing contact, and in that a substantially physical coupling between the contacts is achieved due to elimination of the gap between the contacts.
