Abstract

SF₆-Eindruckschalter mit einer durch die Schaltbewegung betätigbaren Kompressionseinrichtung. SF₆ impression switch with one that can be actuated by the switching movement Compression device.

Die Lichtbogenenergie stromstarker Lichtbögen behindert bei solchen Schaltern die Beblasung des Lichtbogens mit kaltem Isoliergas hoher Dichte und wirkt auf den Antrieb zurück. The arc energy of high-current arcs hinders such switches blowing the arc with cold insulating gas of high density and works back to the drive.

Durch den erfindungsgemäßen Schalter wird die Lichtbogenenergie für die Beblasung genutzt und die Rückwirkung auf den Antrieb dadurch verhindert, daß zwischen der Kompressionseinrichtung und der Schaltstrecke (4) eine Druck­ kammer (3) und ein Gasspeicherraum (9) angeordnet sind, wobei die Druck­ kammer (3) zur Kompressionseinrichtung eine durch ein Verschlußorgan (8) verschließbare Einströmöffnung (7) aufweist, das Verschlußorgan (8) bei verschlossener Einströmöffnung (7) eine Öffnung (10) zwischen dem der Schaltstrecke (4) abgewandten Teile des Gasspeicherraums (9) und der Druckkammer (3) öffnet, das Verschlußorgan (8) den zurückgelegten Schaltweg oder durch die auftretenden Drücke gesteuert ist und die Druck­ kammer (3) in Richtung der Schaltstrecke (4) eine durch ein Rückschlagven­ til (6) verschließbare Ausströmöffnung (5) aufweist. The arc energy for the Blowing used and the effect on the drive thereby prevented that a pressure between the compression device and the switching path (4) chamber (3) and a gas storage space (9) are arranged, the pressure chamber (3) to the compression device through a closure member (8) Has closable inflow opening (7), the closure member (8) closed inflow opening (7) an opening (10) between which the Switching section (4) facing away from the parts of the gas storage space (9) and Pressure chamber (3) opens, the closure member (8) the covered Switching path or controlled by the pressures occurring and the pressure chamber (3) in the direction of the switching path (4) by a Rückschlagven til (6) closable outflow opening (5).
