Abstract
Pressurized gas circuit-breaker for very high voltages having opening and closing resistors, comprising, in a main insulative enclosure (1), a fixed contact (21, 101), a movable contact (32, 34, 62), a closing resistor (8) and a device (19) for inserting the closing resistor, the circuit-breaker further comprising, in an auxiliary insulative enclosure (120), a movable auxiliary contact (121), a fixed auxiliary contact (131) and an opening resistor (133), the circuit-breaker being characterized in that the movable auxiliary contact (121) is moved by a mechanism disposed in a casing (150) common to both enclosures (1, 120) and on the side of the fixed contact (21, 101), the mechanism comprising a link-crank assembly (152, 152') and a bell-crank lever having two arms (154A, 154B). Application to circuit-breakers for very high voltages.
