A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.

Switch

The disclosure relates to a medium-voltage or high-voltage switchgear comprising at least one switching device. The aim is to enable the associated switchgear to be functionally integrated with the greatest possible technical functional comfort. To this end, the switching device or the switching devices is/are respectively provided with a data and/or control interface, with the aid of which the same is/are linked to an electronic master terminal via a data and/or control line such that the switching devices can be triggered by the electronic master terminal and the control thereof can be integrated in a process, particularly an industrial process.
