Description

Es ist bekannt, die Funkenkammer von elektrischen Leistungsschaltern, mit Querrippen oder Querwänden zwischen den beiden Seitenwänden zu versehen, tun den Lichtbogen' durch die Berührung mit deren Flächen zu kühlen, ihn gegebenenfalls· fächerförmig· zu unterteilen und ihn nach den AustrittssteUen aus der Funkenkammer hinzuleiten. Diese Querwände oder -rippen erstreckten sich bisher im wesentlichen geradlinig, da sie meistens ,aus ebenen Zementasbestplatten hergestellt und zwischen den aus1 dem gleichen Stoff hergestellten Seitenwänden eingeschoben waren. Infolge dieser geradlinigen FormIt is known to provide the spark chamber of electrical circuit breakers with transverse ribs or transverse walls between the two side walls, to cool the arc by touching their surfaces, to divide it into a fan shape if necessary and to lead it to the exit points from the spark chamber . These cross-walls or ribs extending so far substantially straight, as they were usually made of asbestos cement flat sheets and inserted between the made of the same material 1 side walls. As a result of this rectilinear shape

ig passen sich diese Rippen oder Wände der natürlichen Strömungsrichtung des Lichtbogens und seiner Gase nur mangelhaft an, zumal wenn die Ausströmungsrichtung des Lichtbogens nicht geradlinig, sondern gekrümmt ist, so daß Stauungen auftreten können. ig these ribs or walls adapt to the natural flow direction of the arc and its gases are poor, especially when the outflow direction of the arc is not straight but curved so that congestion can occur.

Es werden daher bei .einer Funkenkammer mit an deren seitlichen Stirnflächen gelegenen Gasauslässen gemäß der Erfindung derart ausgebildete Querrippen vorgesehen, daß der Lichtbogen von seiner Eintrittsstelle in die Funkerikammer aus stromlinienartig· nach den seitlich gelegenen Austrittsstellen geleitet wird.There are therefore with .einer spark chamber with located on their lateral end faces Gas outlets according to the invention provided such designed transverse ribs that the arc streamlined from its entry point into the radio operator's chamber is directed to the exit points on the side.

Die Ausbildung einer Funkenkammer nach 31· der Erfindung ist im einzelnen an einem Ausführungsbeispiel in Fig. 1 und 2 dargestellt. Fig. ι zeigt eine Hälfte der zweiteiligen, in der Längsmitte geteilten Funkenkammer. Der Lichtbogen tritt bei 17 in die Kammer ein und läuft auf den beiden Funkenhörnern 18, gegebenenfalls unter dem Einfluß einer Luft- oder magnetischen Blasung entlang. Auf der Seitenwand der Funkenkammer sind Rippen 50 aufgesetzt, die zunächst senkrecht zur Entstehungslinie des Lichtbogens nach oben und in der oberen Hälfte der Kammer derart stromlinienartig gebogen verlaufen, daß sie den Lichtbogen und seine Gase ohne Stauung nach den in den seitlichen Stirnflächen 51, 52 gelegenen Aus-The formation of a spark chamber according to the invention is in detail on one Exemplary embodiment shown in FIGS. 1 and 2. Fig. Ι shows one half of the two-part, Spark chamber divided in the longitudinal center. The arc occurs at 17 in the Chamber and runs on the two spark horns 18, possibly under the influence along an air or magnetic bubble. On the side wall of the spark chamber ribs 50 are placed, initially perpendicular to the line of origin of the arc upwards and in such a streamlined manner in the upper half of the chamber are curved so that they move the arc and its gases without congestion to the lateral end faces 51, 52 located

trittssteilen leiten. Die Austrittsstellen sind nicht völlig offen, sondern durch Querwände 25 aus Metall oder Isolierstoff zur weiteren Entionisierung der Lichtbogengase unterteilt. Die obere Seite der Funkenkammer kann durch eine Platte 53 ganz oder zum Teil abgedeckt sein.guide step parts. The exit points are not completely open, but rather through transverse walls 25 made of metal or insulating material for further deionization of the arc gases. The upper side of the spark chamber can be completely or partially covered by a plate 53 be.

Die beiden Hälften des. Lichtbogens treten somit aus den beiden Stirnseiten der Funkenkammer mit entgegengesetzter Strömungsrichtung aus, so daß ein Zusammenschlagen der beiden Hälften ausgeschlossen ist.The two halves of the arc thus emerge from the two end faces of the spark chamber with opposite flow direction, so that a collision of the two halves is impossible.

Bei mehrpoligen Schaltern kann gemäß der Erfindung eine die Pole durch Isolierwände 33 voneinander scheidende Poltrennkammer nach Fig. 2 angeordnet werden. Die Stirnwand 29 dieser Kammer wird zweckmäßig an ihrer den Funkenkammerstirnseiten zu gelegenen Innenwand nach Art einer 3 geformt. Die aus den Stirnseiten austretenden Lichtbogengase werden hierdurch in der Mitte an dem Vorsprung 31 geteilt und in Richtung der Pfeile umgelenkt, so daß sie durch die Berührung mit den Wänden der Poltrennkammer sich auf eine unschädliche Temperatur abkühlen können.In the case of multi-pole switches, according to the invention, one of the poles can be protected by insulating walls 33 mutually separating pole separation chamber according to FIG. 2 are arranged. The front wall 29 this chamber is expediently located on its inner wall facing the spark chamber front sides shaped like a 3. The arc gases emerging from the end faces are thereby divided in the middle at the projection 31 and deflected in the direction of the arrows, so that they cool down to a harmless temperature by contact with the walls of the pole separation chamber can.
