Abstract

Der Hochspannungsschalter hat einen von einer Kolben-Zylinder-Einheit (27) linear längs einer Achse eines mit Isolieröl gefüllten Gefäßes (20) verschiebbar gelagerten Schaltkopf (10), auf dem mindestens zwei elektrisch leitend miteinander verbundene Kontaktstücke (a′, b′) angeordnet sind, die auf derselben Seite des Schaltkopfes (10) in achsparalleler Richtung je einen festen Gegenkontaktstück (a, b) zugewandt sind. Mindestens das eine Kontaktstück (a, b) jedes Kontaktstückpaares ist nachgiebig ausgebildet, so daß es dem jeweils anderen Kontaktstück bei der gegenseitigen Berührung elastisch nachgibt. The high voltage switch has one of one Piston-cylinder unit (27) linear along an axis of a Sliding vessel (20) filled with insulating oil mounted switch head (10) on which at least two contact pieces connected to one another in an electrically conductive manner (a ′, b ′) are arranged on the same side of the Switch head (10) each in the axis-parallel direction fixed counter contact piece (a, b) are facing. At least which is a contact piece (a, b) of each contact piece pair resiliently trained so that it is the other Contact piece elastic when touching each other yields.
