Description
Die Erfindung betrifft eine weitere Verbesserung der nach Patent 644889 aus einem Drahtbündel bestehenden Einsatzkörper für Einrichtungen zur Verminderung der Dampfentwicklung bei Metalldampfentladeapparaten, insbesondere bei Metalldampfgleichrichtern, bei denen als Lichtbogenansatz ein aus dem Dampf entwickelnden Metallvorrat herausragender, stiftartiger, dochtähnlich wirkender Körper vorgesehen ist, der auch bei höheren Belastungen die für die Aufrechterhaltung der Entladung notwendige Metallmenge fördert, und bei denen Mittel vorhanden sind, die verhindern, daß der Lichtbogenansatz zur Verdampfung des Metallvorrates beiträgt.The invention relates to a further improvement of the patent 644889 from a Wire bundle existing insert body for devices to reduce the development of steam with metal vapor discharge devices, especially with metal vapor rectifiers, in which a metal reserve emerging from the steam is the starting point of the arc, A pen-like, wick-like body is provided, which is also responsible for maintaining it at higher loads the discharge promotes the necessary amount of metal, and in which means are present to prevent the arc approach contributes to the evaporation of the metal supply.
Bestehen die Einsatzkörper gemäß dem Hauptpatent aus Drähten, die beispielsweise von einer Quarzhülse o. dgl. zusammengehalten werden, so besteht die Gefahr, daß die Enden der Drähte, an denen der Lichtbogen ansetzt, sehr erheblich beansprucht, zerstört oder zerstäubt werden, je nachdem, aus welchem Material die Drähte bestehen.If the insert body according to the main patent consists of wires, for example Are held together by a quartz sleeve or the like, there is a risk that the Ends of the wires to which the arc starts, very heavily stressed, destroyed or atomized, depending on the material the wires are made of.
Gemäß der vorliegenden Erfindung wird das Zerstören der Drahtenden des Einsatzkörpers dadurch verhindert, daß die in der Entladungsbahn des Lichtbogens liegenden freien, vorzugsweise eben abgeschnittenen Enden der Drähte mittels einer dünnen Schicht eines gegen die vom Lichtbogen herrührende Beanspruchung beständigen, porösen Stoffes abgedeckt sind.According to the present invention, the destruction of the wire ends of the insert body this prevents the free, preferably flat cut off lying in the discharge path of the arc Ends the wires by means of a thin layer of one against the one resulting from the arc Resistant, porous material are covered.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Zeichnung zeigt den unteren Teil eines Glasgleichrichters.An exemplary embodiment is shown in the drawing. The drawing shows the lower part of a glass rectifier.
In dem Kathodenquecksilber ι ist ein Einsatzkörper 2 angeordnet. Der Einsatzkörper hat einen das Kathodenquecksilber größtenteils abdeckenden Schirm 3, der einen vorzugsweise aus Isoliermaterial bestehenden Zylinder 4 umschließt, in dem die Drähte 5 liegen. Auf die oberen Enden der Drähte 5 ist eine dünne Platte 6 aus gesintertem Wolfram gelegt. Der Kathodenbehälter, der im Ausführungsbeispiel aus Glas besteht, ist mit 7 bezeichnet.In the cathode mercury ι is an insert body 2 arranged. The insert body has a screen 3 which largely covers the cathode mercury and which preferably has a made of insulating material encloses cylinder 4 in which the wires 5 lie. A thin plate 6 made of sintered tungsten is placed on the upper ends of the wires 5. The cathode container, which consists of glass in the exemplary embodiment, is denoted by 7.
