Abstract

A high-voltage circuit breaker is housed in a first compartment (20) with SF6 under pressure and comprises an operating mechanism (30) with a pneumatic jack (46) actuated by the gas contained in the first compartment (20) via closing and opening valves (54, 60). The jack (46) is located in a sealed enclosure (34) bounding a second compartment (32) at low pressure playing the role of expansion volume of the gas expelled from the jack (46) at the end of travel of the piston (48). The gas pressure in the jack is controled by means of a control device (98) sensitive to the temperature variation of the gas under pressure in the first compartment (20).
