An adjusting device adjusts the stroke of a vacuum switching tube and the bias of a contact compression spring of a switching device mechanism, the spring being paired with the vacuum switching tube, for a medium-voltage switch and/or high-voltage switch. The adjusting device can be driven by a switch shaft, the switch shaft is connected to a transmission element via a connection element, and the transmission element can be connected to a movable switch contact of a medium-voltage switch and/or a high-voltage switch. The transmission element is arranged in a rotatable manner and in a laterally movable manner in the connection element along a recess.

Adjusting device and method for adjusting switching device mechanisms

A method for establishing a materially bonded current path connection in low-voltage, medium-voltage and/or high-voltage installations having long-term stability includes providing a first part and/or a second part of a current path with a nanomaterial at least in one region. The first part and the second part of the current path are force-lockingly or form-lockingly connected at least in the respective regions. A supply of a reaction energy together with the nanomaterial creates a conductive and bonded connection between the first part and the second part of the current path. A low-voltage installation, a medium-voltage installation and/or a high-voltage installation is also provided.

Low-, medium- and/or high-voltage installation with a bonded current path connection with long-term stability by means of nanomaterials, and method for producing said current path connection

A drive, for a switching device including a contact system with a fixed and a moving contact, including an actuator for operating the moving contact for closing or opening the contact system, and also a mechanical transmission device arranged between the moving contact and the actuator. The transmission device includes a toggle joint mechanism formed by a folding lever, pivotable about a stationary bearing, and a coupling element, connected to the folding lever via a moving bearing. The toggle joint mechanism is pivotable between a first end position and a second end position. When the changeover is made from the first to the second end position or vice versa, a maximum extended position occurs. The coupling element holds the moving contact in that position which closes the contact system in the first end position and in that position in which the contact system is open in the second end position.
