Abstract

In an arrangement and a method for driving a movable contact of a vacuum interrupter in a high-voltage circuit breaker, an actuating rod forms an element of a kinematic chain of the high-voltage circuit breaker. A lever element can rotate about an axis and can be mechanically connected to a drive via a connection element. A coupling element is configured to mechanically movably couple the actuating rod and the lever element. The actuating rod and the coupling element each have a longitudinal axis. The longitudinal axes are situated substantially on a common axis at a point in time when a separating action of the vacuum interrupter occurs.
