Abstract
A high-voltage circuit breaker is described having arcing contacts, which can be driven in opposite directions, as well as corner gears that are coupled, via a driving rod, with the driven insulating nozzle surrounding the arcing contacts, with the corner gears being designed as a lever mechanism using a two-armed control lever. The one end of the control lever is shaped like a fork, with a journal that is attached to the driving rod engaging with this end. The other end of the control lever is coupled, via a reciprocating element, with the head piece of the second arcing contact, which is driven in the opposite direction.
Claims4
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;
- and
- a 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.
