Abstract (en)

[origin: US6271494B1] 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.
