Description

Funkenkammer mit versetzten Querwänden für Hochspannungsluftschalter Im Hauptpatent ist eine Funkenkammer für Luftschalter mit rippenförmigen Querwänden beschrieben, die abwechselnd von beiden Kammerlängswänden ihren Anfang nehmen, aber nicht bis an die gegenüberliegende Wand heranreichen. Das Ausführungsbeispiel zeigt Querwände, die in der Querrichtung der Kammer an allen Stallen die gleiche Breite aufweisen. Es hat sich nun gezeigt, daß sich der Lichtbogen beim Auftreffen auf die unteren Ränder der Querwände stauen kann, so daß Unregelmäßigkeiten, Rückschläge und verspätetes Löschen des Lichtbogens nicht ausgeschlossen sind.Spark chamber with offset transverse walls for high-voltage air switches In the main patent is a spark chamber for air switches with rib-shaped transverse walls described, which start alternately from both longitudinal walls of the chamber, but do not reach the opposite wall. The embodiment shows Transverse walls that are the same width in the transverse direction of the chamber at all stables exhibit. It has now been shown that the arc on impact the lower edges of the transverse walls can jam, so that irregularities, setbacks and delayed extinguishing of the arc cannot be ruled out.

Nach der Erfindung wird daher der Lichtbogen nur allmählich in die durch die Querwände gebildeten Zellen eingeführt, indem die Wände unten abgeschrägt sind und erst weiter oben ihre volle Breitenabmessung erhalten.According to the invention, the arc is therefore only gradually in the cells formed by the transverse walls are introduced by making the walls beveled at the bottom and are only given their full width dimensions further above.

Wie dies beispielsweise ausgeführt werden kann, geht aus der Zeichnung hervor, in der die Funkenkammer isn Querschnitt (entsprechend Fig. i des - Hauptpatents) dargestellt ist. Die Elektrode ist mit a, die Längswand der Funkenkammer mit b und die Querrippen sind mit d bezeichnet. Erfindungsgemäß sind deren untere Flächen e an dem Ende, wo der Lichtbogen zuerst auf sie trifft, abgeschrägt. Die Steilheit der Abschrägung richtet sich nach den Bedürfnissen des einzelnen Falles..How this can be carried out, for example, goes from the drawing in which the spark chamber isn cross-section (corresponding to Fig. i of the main patent) is shown. The electrode is marked with a, the longitudinal wall of the spark chamber with b and the transverse ribs are denoted by d. According to the invention, their lower surfaces e beveled at the end where the arc first meets them. The steepness the bevel depends on the needs of the individual case.

PATENTANSPRUCII Funkenkammer mit versetzten Querwänden für Hochspannungsluftschalter nach Patent 435 839, dadurch gekennzeichnet, daß die der Lichtbogenentstehungsstelle zunächst liegenden Stirnflächen der Querwände derart abgeschrägt sind, daß die Querwände mit zunehmender Entfernung vom Lichtbogenursprung sich verbreitern und erst in gewisser Entfernung ihre volle Breite erreichen. SPARK CHAMBER with offset transverse walls for high-voltage air switches according to patent 435 839, characterized in that the end faces of the transverse walls which are closest to the point of arc formation are beveled in such a way that the transverse walls widen with increasing distance from the origin of the arc and only reach their full width at a certain distance.
