Abstract

Erfindungsgemäß ist der Dampfschirm in der Mittelebe­ ne zwischen den geöffneten Kontakten (2, 4) mit einer radial nach innen gerichteten Wölbung versehen. In einer Ausfüh­ rungsform des Vakuumschalters mit metallischem Gehäuse (6) kann das Gehäuse selbst die Wölbung enthalten oder auch mit einer zusätzlichen, entsprechend gestalteten Ein­ lage (12) versehen sein. Die Neigung der abfallenden Flan­ ken der Wölbung ist so gewählt, daß die vom Lichtbogen ausgehende Plasmaströmung in axialer Richtung abgelenkt wird. Damit wird insbesondere bei einpoligen Schaltern mit verhältnismäßig langen Bogenzeiten die Belastung des Dampfschirmes vermindert. According to the steam screen in the middle level ne between the open contacts (2, 4) with a radial provided inward curvature. In an execution Form of the vacuum switch with a metallic housing (6) the housing itself can contain the bulge or also with an additional, appropriately designed one location (12). The slope of the sloping flan ken the curvature is chosen so that the arc outgoing plasma flow deflected in the axial direction becomes. This is particularly useful for single-pole switches relatively long arc times the burden of Steam screen reduced.
