Description
Metalld'ampfentladungsgefäl3 mit einem in die Kathode eingesetzten dochtartigen Einsatzkörper Die Erfindung betrifft ,ein Metalldampf -entladungsgefäß mit :einem in der Kathode befindlichen Einsatzkörper.Metal vapor discharge gradient with an inserted into the cathode wick-like insert body The invention relates to a metal vapor discharge vessel with: an insert body located in the cathode.
Metalldampfentladungsgefäße mit einem in die Kathode eingesetzten, das Kathodenm!etall nach Arteines Dochtes bis zu der an seinem oberen Ende 'befindlichen Ansatzstelle emporziehenden Einsatzkörper, der bis auf die Lichtbogenansatzstelle von einer Schutzhülse aus einem Metall. von großer Temperaturbeständigkeit, geringer Neigung zur Zerstäübung in der Entladungsbahn und geringer Löslichkeit in dem flüssigen Kathodemnetall umgeben ist, wurden bereits früher vorgeschlagen. Die bekannten Entladungsgefäße haben jedoch den Nachteil, da,ß sie namentlich bei Entladungsapparaten sehr großer Leistung nach längerem Betrieb schadhaft werden. Die Schutzhülsen erhalten zunächst feine Risse und Sprünge, die schließlich zum Abplatzen des Sdhutzkörpers führen, so daß der Einsatzkörper in dem Entladungsapparat ungeschützt ist.Metal vapor discharge vessels with an inserted into the cathode, the cathode metal in the manner of a wick up to that at its upper end Attachment point pulling up insert body, which is up to the arc attachment point from a protective sleeve made of a metal. of high temperature resistance, lower Tendency to atomize in the discharge path and poor solubility in the liquid Cathode metal surrounds have been proposed earlier. The well-known discharge vessels however, they have the disadvantage that they are very large, especially in the case of discharge apparatus Performance can become defective after prolonged use. Get the protective sleeves initially fine cracks and fissures, which eventually lead to flaking of the protective body, so that the insert body is unprotected in the discharge apparatus.
Dieser Nachteil: wird gemäß der vorliegenden Erfindung dadurch behoben, da.ß die Schutzhülse vollkommen glatt ausgeführt ist und abgerundete Kanten aufweist, so daß keinerlei Angriffsstellen für im Entladungsapparat auftretende zerstörende Ers'cheinungten vorhanden 'sind.This disadvantage: is eliminated according to the present invention by da.ß the protective sleeve is completely smooth and has rounded edges, so that no points of attack for destructive ones occurring in the discharge apparatus Appearances are present.
Die neuen Schutzhülsen bestehen aus einem Metallrohr. Als Werkstoff für dieses Metallroter dient ein Metall, das eine große Temperaturbeständigkeit, geringe Zersitäubung in der elektrischen Entladung und geringe Löslichkeit im flüssigen Metall aufweist. Als Metall dieser Beschaffenheit eignet sich besonders Wolfram. Es ist bei der Herstellung von metallenen Schutzrohren für Elektrodendochte darauf zu achten, daß diese Wolframrohre keinerlei starke Krümmungen und Kanten aufweisen, an denen ein kapillares Hochsaugen der Elektrodenflüssigkeit eintreten könnte.The new protective sleeves consist of a metal tube. As a material for this metal roter a metal is used that has a high temperature resistance, low atomization in electrical discharge and low solubility in liquid Has metal. Tungsten is particularly suitable as a metal of this nature. It is used in the manufacture of metal protective tubes for electrode wicks make sure that these tungsten tubes do not have any sharp curves or edges, at which capillary suction of the electrode liquid could occur.
