Abstract:
A high-voltage circuit-breaker, comprising:a fixed contact carrying a persistent current;an axially drivable contact carrying the persistent current;a first arcing contact and a second arcing contact, the first arcing contact and the second arcing contact coaxially surrounded by the fixed contact;an insulating nozzle firmly connected to the drivable contact and to the first arcing contact;an axially displaceable field electrode surrounding the second arcing contact; andgearing displacing the field electrode, the gearing including:a first coupling shank coupled via the insulating nozzle to the drivable contact, the first coupling shank extending in a direction of a longitudinal axis of the circuit-breaker,a second coupling shank extending parallel to the first coupling shank and coupled to the field electrode,a swivel-mounted lever coupled to the first coupling shank,a pin secured to a swivelling portion of the lever and passing through a swivelling plane of the lever, the second coupling shank being coupled to the pin, anda plate coupled to the second coupling shank and having a connecting link guide, the pin engaging with the connecting link guide, the connecting link guide having a first section extending in a direction one of parallel and nearly parallel to a longitudinal direction of the first coupling shank, and having a second curved section allowing the pin to deflect in a direction one of perpendicular and nearly perpendicular to the longitudinal direction of the first coupling shank.
