ARRANGEMENT AND METHOD FOR DRIVING A MOVABLE CONTACT OF A VACUUM INTERRUPTER IN A HIGH-VOLTAGE CIRCUIT BREAKER

摘要

The invention relates to an arrangement (1) and a method for driving a movable contact of a vacuum interrupter in a high-voltage circuit breaker, having: an actuating rod (7) as an element of a kinematic chain of the high-voltage circuit breaker; a lever element (3) which can rotate about an axis (4) and which can be mechanically connected to a drive via a connection element (6, 12); and a coupling element (5) which is designed to mechanically movably couple the actuating rod (7) and the lever element (3). The actuating rod (7) and the coupling element (5) each have a longitudinal axis, these longitudinal axes being situated substantially on a common axis (8) at the point in time when a separating action of the vacuum interrupter occurs.
