Description

Die Erfindung betrifft eine Einrichtung zur Steuerung des Lichtbogens in Metalldampf-Entladungsröhren, insbesondere in Quecksilberdampfgleichrichtern, in deren Anodenhülsen je wenigstens ein metallenes Gitter isoliert 'eingelegt ist; sie bezweckt, die Rückzündungen in mit Wechselspannung betriebenen Metalldampf-Entladungsröhren dieser Bauart zu unterdrücken. Erfindungsgemäß ist bei derartigen Gleichrichtern das Gitter mit einem metallenen Apparateteil verbunden, der mit dem Metalldampf in enger Berührung steht, jedotih von der Kathode elektrisch isoliert und gegen die Anode durch die Anodenhülse elektrostatisch abgeschirmt ist. Dadurch werden gegenüber den bekannten Gitteranordnungen folgende Vorteile erreicht. Es wird keine Batterie benötigt, die Steuerung der Gitter geschieht durch den Lichtbogen selbsttätig. Die Wirkung des Gitters ist auch dann vorhanden, wenn die Gasentladungsröhre mit Wechselspannung, wie im Falle eines Gleichrichters, betrieben wird.The invention relates to a device for controlling the arc in metal vapor discharge tubes, especially in mercury vapor rectifiers, in the anode sleeves of which there is at least one metal Grid insulated 'is inserted; its purpose is to control the reignitions in AC voltage operated To suppress metal vapor discharge tubes of this type. According to the invention In rectifiers of this type, the grid is connected to a metal part of the apparatus, which is in close contact with the metal vapor, but from the cathode electrically isolated and electrostatically shielded from the anode by the anode sleeve is. As a result, the following advantages are achieved over the known grid arrangements. No battery is required, the grid is controlled automatically by the arc. The effect of the The grid is also present when the gas discharge tube is operated with alternating voltage, as in the case of a rectifier.

Die Figur zeigt schematisch ein Ausführungsbeispiel der Einrichtung gemäß der Erfindung, ι ist das Entladungsgefäß und 2 eine Anode, die durch den Isolator 3 gegen das Gefäß 1 isoliert ist. 4 ist die Anodenhülse, die in bekannter Weise zum Schutz der Anode gegen die aufsteigenden Metalldämpfe angebracht ist. 5 ist ein metallenes Gitter, das in die Anodenhülse 4, und zwar praktisch mit einigen Millimetern Abstand vom Anodenkopf weg, isoliert eingelegt, bei 6 isoliert aus der Hülse 4 herausgeführt und mittels eines Widerstandes 7 mit dem Gefäß 1 verbunden ist.The figure shows schematically an embodiment of the device according to the invention, ι is the discharge vessel and 2 an anode which is insulated from the vessel 1 by the insulator 3. 4 is the anode sleeve, in a known way to protect the anode against the rising metal vapors is appropriate. 5 is a metal grid that is inserted into the anode sleeve 4, namely practically a few millimeters away from the anode head, insulated inserted, insulated at 6 guided out of the sleeve 4 and connected to the vessel 1 by means of a resistor 7 connected is.

Da es sich meist um Entladungsgefäße mit mehreren Anoden handelt, können entweder alle Anodengitter miteinander verbunden und der Verbindungspunkt direkt oder über einen Widerstand 7 mit dem Gehäuse verbundenSince these are mostly discharge vessels with several anodes, either all anode grids connected to each other and the connection point directly or via a Resistor 7 connected to the housing

werden, oder es kann die Anordnung im Sinne der Figur durch die Verbindung jedes einzelnen Gitters mit dem Gefäß durchgeführt werden. Eine andere Anordnung, die ebenfalls in Frage kommt und denselben Zweck erfüllt, besteht darin, daß man die Gitter anstatt an das Gefäß an irgendeinen leitenden Schirm legt, der mit dem Metalldampf in enger Berührung, hingegen vor dem direkten Einfluß der von den Anoden ausgehenden Feldlinien durch die Anodenhülsen elektrostatisch geschützt ist. Diese letzte Anordnung kommt in erster Linie für Glasgefäße in Frage, während die vorher genannten Anordnungen sich besonders für Metallgefäße eignen. Es könnten pro Anodenhülse auch mehrere Gitter 5 vorgesehen sein.be, or it can be the arrangement in the sense of the figure by connecting each individual grids can be carried out with the vessel. Another arrangement that too and serves the same purpose is to use the grids instead of to the vessel on any conductive screen that is in contact with the metal vapor close contact, but before the direct influence of that emanating from the anodes Field lines is electrostatically protected by the anode sleeves. This last arrangement is primarily used for glass vessels, during the aforementioned arrangements are particularly suitable for metal vessels. It could also be per anode sleeve several grids 5 may be provided.
