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.

An arrangement for driving a movable contact of a vacuum interrupter in a high-voltage circuit breaker, the arrangement comprising:
- a switching rod forming an element of a kinematic chain of the high-voltage circuit breaker, said switching rod having a longitudinal axis;
- a lever element rotatably mounted about an axis and configured to be mechanically connected to a drive by way of a connecting element;
- a coupling element configured to mechanically movably connect said switching rod with said lever element, said coupling element having a longitudinal axis;
- said switching rod having a circular-cylindrical shape, with a cuboidal end movably fastened to said coupling element;
- said longitudinal axis of said switching rod and said longitudinal axis of said coupling element being oriented substantially on a common axis at a moment in time at which a separating action of the vacuum interrupter takes place.
A method for driving a movable contact of a vacuum interrupter in a high-voltage circuit breaker, the method comprising:
- providing a switching rod with a circular-cylindrical shape, and a cuboidal end movably fastened to a coupling element;
- moving a connecting element by a drive and thereby moving a lever element which is rotatable about an axis and which thereby transmits mechanical kinetic energy to the switching rod by way of the coupling element;
- transmitting with the switching rod, which forms a member of a kinematic chain of the high-voltage circuit breaker, kinetic energy to an electrical contact of the vacuum interrupter during switching;
- and
- aligning a longitudinal axis of the switching rod and a longitudinal axis of the coupling element to substantially form a common axis at a time at which a separating action of the vacuum interrupter takes place.
