Description
Mehrpoliges elektrisches Schaltgerät Bei mehrpoligen elektrischen Schaltgeräten, die aus Einzelschaltern mit auf eigenen Isolierstoffträgem zusammengefaßten festen Kontaktelementen mit Anschlußstücken und Lichtbogenkammern zusammengesetzt sind und einen gemeinsamen Antrieb für die beweglichen Kontaktelemente der einzelnen Pole haben, macht die gleichmäßige Einstellung des Kontaktdruckes für die einzelnen Pole, die mit Rücksicht auf eine gleichmäßige Kontaktabnutzung und damit gleichmäßige Schaltstücklebensdauer wichtig ist, Schwierigkeiten. Gemäß der Erfindung werden die Schwierigkeiten in einfacher Weise dadurch behoben, daß die Einzelschalter über verschiebbare keilförmige Zwischenstücke auf dem gemeinsamen Traggerüst gelagert sind.Multipole electrical switching device For multipole electrical Switching devices made up of individual switches combined with their own insulating material Fixed contact elements assembled with connectors and arc chambers are and a common drive for the movable contact elements of the individual Having poles makes the contact pressure evenly adjusted for the individual Poles that are designed with a view to uniform contact wear and thus uniform Contact life is important, difficulties. According to the invention the difficulties solved in a simple manner that the individual switch over displaceable wedge-shaped spacers mounted on the common support frame are.
Die Zwischenstücke werden verschieblich entweder mit dem Traggerüst oder mit dem Isolierstoffträger der Einzelschalter verbunden. Eine den keilförmigen Zwischenstücken entsprechende schiefe Ebene kann an der Unterseite der Isolierstoffträger oder an der Grundplatte vorgesehen werden.The intermediate pieces can be moved either with the supporting structure or connected to the insulating support of the individual switches. One that is wedge-shaped Intermediate pieces corresponding inclined plane can be on the underside of the insulating material carrier or be provided on the base plate.
In der Zeichnung ist ein Ausführungsbeispiel einer Anordnung gemäß der Erfindung dargestellt. Die aus je einem Isolierstoffträger 1 mit aufgebauten festen Kontaktelementen 2, Anschlußstücken 3 und Blasspulen 4 sowie Lichtbogenlöschkammern 5 bestehenden Einzelschalter sind auf dem gemeinsamen Traggerüst 6 über keilförmige Zwischenstücke 7 gelagert. Diese Zwischenstücke sind auf den Tragschienen 6 gegeneinander verschieblich. Bei dem dargestellten Ausführungsbeispiel ist zu diesem Zweck an den Zwischenstücken je eine Madenschraube 8 befestigt, die eine Mutter 9 trägt, die zwischen zwei mit einer Bohrung für den Durchtritt der Schraube 8 versehenen Flanken 10 der Tragschienen 6 gefaßt ist. Durch Verdrehen der Muttern 9 können somit die keilförmigen Zwischenstücke 7 in der einen oder anderen Richtung gegeneinander verschoben werden, wodurch der Isolierstoffträger 1 des Einzelschalters, der an seiner Unterseite mit einer der Keilfläche der Zwischenstücke 7 entsprechenden schiefen Ebene 11 versehen ist, gehoben bzw. gesenkt wird. Nach entsprechender Einstellung der Höhe des Einzelschalters wird seine Lage durch Befestigungsschrauben 12, die einen Schlitz der keilförmigen Zwischenstücke 7 durchsetzen, festgelegt.In the drawing, an embodiment of an arrangement according to the invention is shown. The individual switches, each consisting of an insulating material carrier 1 with built-up fixed contact elements 2, connecting pieces 3 and blowing coils 4 as well as arc extinguishing chambers 5, are mounted on the common support frame 6 via wedge-shaped spacers 7. These intermediate pieces can be displaced relative to one another on the support rails 6. In the illustrated embodiment, a grub screw 8 is attached to each of the intermediate pieces for this purpose, which carries a nut 9, which is gripped between two flanks 10 of the support rails 6 provided with a bore for the passage of the screw 8. By turning the nuts 9, the wedge-shaped spacers 7 can thus be shifted against each other in one direction or the other, whereby the insulating support 1 of the individual switch, which is provided on its underside with an inclined plane 11 corresponding to the wedge surface of the spacers 7, is raised or lowered will. After the height of the individual switch has been appropriately adjusted, its position is determined by fastening screws 12 which penetrate a slot in the wedge-shaped intermediate pieces 7.
