ABSTRACT:
A gas-insulating switching unit includes a gas-filled housing containing a multi-pole vacuum switch and a three-position circuit breaker arranged below it. The vacuum switch is arranged so that the longitudinal axes of the horizontally positioned vacuum switching tubes are perpendicular to the front wall of the housing. The switch shaft of the circuit breaker is parallel to the front wall of the housing. Actuating rods are sealed against the front wall be bellows and can be used to operate the vacuum switching tubes. The circuit breaker is operated by a drive device via two pivoting levers that can be coupled by means of a fork opening.
