ABSTRACT:
A high-voltage circuit-interrupter for operation in an insulating gas or liquid contained in an enclosure, comprises a generally tubular movable contact assembly mounted for movement relatively to a tubular fixed contact to draw an arc between them. The movable contact assembly comprises a tubular main contact carrying a nozzle and having a relatively-axially-movable auxiliary contact in its interior. A puffer cylinder-and-piston device is arranged to direct a flow of the insulating fluid under pressure through the nozzle and thence into the interiors of the fixed contact and the movable contact assembly through the gap between them on operation of the circuit-breaker. The auxiliary contact is arranged to move relatively to the main contact of the movable contact assembly during the opening stroke of the interrupter and to open a vent valve to allow a part of the fluid flow which has passed through the gap between the separated contact to vent through a radial passage extending through the movable contact assembly, the remainder of the fluid flow being vented through the bore of the tubular fixed contact.
