Abstract:
A high-voltage circuit breaker, comprising:a first axially drivable permanent-current contact;a second stationary permanent-current contact;first and second arcing contacts axially surrounded by the first and second permanent-current contacts, the first and second arcing contacts positioned coaxially and opposite with respect to one another;an insulating nozzle permanently connected to both the first permanent-current contact and the first arcing contact;a sliding contact guiding the second arcing contact;a reciprocating element;corner gears including a two-armed control lever having two stable end positions, a first end of the control lever being shaped like a fork, a second end of the control lever being pivoted on the second arcing contact via the reciprocating element; anda rod-type driving element attached to the insulating nozzle and positioned parallel of the second arcing contact using the corner gears, a driving movement of the first permanent-current contact for driving the first and second arcing contacts in opposite directions being transmitted to the second arcing contact via the driving element, the driving element including a coupling rod having a journal positioned transversely to a direction of travel of the coupling rod, the first end of the control lever providing connecting-link type guidance of the journal.
