Description

Läßt man bei elektrischen Apparaten, wie Schalter, Sicherungen o. dgl., den beim Unterbrechen des Stromes entstehenden Lichtbogen an hörncrförmig ausgebildeten Elektroden frei aufsteigen, so erreicht derselbe bei höheren Spannungen eine außerordentlich große Ausdehnung. Um das Hinausschlagen des Lichtbogens über den Apparat zu verhindern und dem Lichtbogen trotzdem die zum AbreißenIf you leave electrical equipment such as switches, fuses, etc., the interruption The arc created by the current is released on horn-shaped electrodes rise, it reaches an extraordinarily large expansion at higher tensions. In order to prevent the arc from striking the apparatus and still prevent the arc from breaking off

ίο erforderliche Länge zu geben, hat man zwischen den hörnerförmigen Elektroden Wände angeordnet,, um deren dem Lichtbogen zugewandten Kanten dieser sich wellenförmig herumlegen muß.ίο to give the required length, one has between The horn-shaped electrodes are arranged around the walls facing the arc Edges of this must lie around in a wave shape.

Vorliegende Erfindung besteht in einer Einrichtung, um den Lichtbogen möglichst in der Mitte dieser Wände zu halten.The present invention consists in a device to the arc as possible in to keep the center of these walls.

Auf der Zeichnung ist die Erfindung in den Fig. ι bis 3 beispielsweise dargestellt.In the drawing, the invention is shown in FIGS. Ι to 3, for example.

Fig. ι zeigt einen Schalter mit zwischen den hörnerartigen Elektroden 1 und 2 in dem Wege des Lichtbogens 3 angeordneten Wänden 4, welche bewirken, daß der Lichtbogen sich nicht frei ausbilden kann, sondern sich vielmehr um die unteren Kanten der Zwischenwände wellenförmig herumlegt und zwischen den Wänden so lange aufsteigt, bis seine Gesamtlänge der Abreißlänge, entspricht. Fig. Ι shows a switch with between the horn-like electrodes 1 and 2 in the Paths of the arc 3 arranged walls 4, which cause the arc to can not form freely, but rather around the lower edges of the partition walls Lays around in a wave shape and rises between the walls until its total length corresponds to the tear-off length.

Fig. 2 zeigt die Anordnung von Zwischenwänden 4 zu gleichem Zwecke bei einem bekannten Hörnerblitzableiter.Fig. 2 shows the arrangement of partition walls 4 for the same purpose in a known one Horn lightning arrester.

Fig. 3 ist eine Ansicht einer einzelnen Zwischenwand 4 in größerem Maßstabe.Figure 3 is a view of a single partition 4 on a larger scale.

Gemäß vorliegender Erfindung sind nun diese Zwischenwände 4 an der dem Lichtbogen zugewandten Seite in der Mitte mit einer · Aussparung 5 ■ versehen. Ordnet man, wie es vielfach bei Schaltern o. dgl. geschieht, die hörnerartigen Elektroden zwischen Seitenwänden 6 (Fig. ι und 3) an, so ist es um so mehr nötig, daß der Lichtbogen möglichst in der Mitte zwischen diesen Seitenwänden bleibt. ' \According to the present invention, these partition walls 4 are now on the arc The side facing it is provided with a · recess 5 · in the middle. If you order As is often the case with switches or the like, the horn-like electrodes between side walls 6 (Fig. Ι and 3), so it is all the more necessary that the arc as possible remains in the middle between these side walls. '\

Da die Zwischenwände ah der dem Lichtbogen zugewandten Seite stärker angegriffen werden als an anderen Stellen, und zwar aus dem Grunde, weil der Lichtbogen während der ganzen Zeit seines Bestehens diese Kanten umspielt, so ist es zweckmäßig, dieselben aus einem Material höherer Feuerfestigkeit 5<> herzustellen bzw. mit einem solchen Material zu bedecken. Außer Metall können Armierungen aus Graphit, Kohle oder mehrere dieser Materialien gleichzeitig Verwendung finden.Since the partition walls are attacked more strongly on the side facing the arc be than in other places, for the reason that the arc is during has played around these edges throughout its existence, it is expedient to use them made of a material of higher fire resistance 5 <> to produce or to cover with such a material. In addition to metal, reinforcements can be used made of graphite, carbon or several of these materials can be used at the same time Find.
