 EMI1.1 
 



   Bei Metalldampfgleichrichtern grosser Leistung bereitet die vakuumdichte Einführung der Elektroden beträchtliche Schwierigkeiten, weil man genötigt ist, Materialien zu ver-   wenden die elektrisch isolieron   und sich auch bei hohen Erwärmungen nicht in anderer Weise als die benachbarten Teile der Gefässe bzw. der Elektrode ausdehnen. Aus diesem Grande wurden bereits die verschiedensten kombinierten Dichtungen vorgeschlagen. Die Vereinigung mehrerer ungleichartiger Dichtungselemente ergibt eine verwickelte Bauart und dadurch die erhöhte Möglichkeit von Betriebsstörungen. 



   Gemäss der Erfindung wird der Teil der Gefässwand, der mit der Dichtungsstelle in Berührung kommt, durch den also die Elektrode eintritt, ans einem Stoffe hergestellt, der den gleichen Ausdehnungskoeffizienten besitzt wie das zur elektrischen Isolierung der Elektrode dienende Zwischeumaterial. Beispielsweise kann das letztere aus Porzellan 
 EMI1.2 
 



  Der mit dem Porzellan ring in   Berührung stehende Nickelstahlring   wird durch Schweissen mit dem Gehäuserand verbunden und dadurch die ungleiche Ausdehnung zwischen Nickelstahlring und Gehäusewand durch innere Spannungen aufgenommen, während zwischen   Nickelstahl-und Porzellanring   bei der Erwärmung keinerlei Verschiebung stattfindet. 



  Die Dichtung zwischen Porzellan- und Nickelstahiring kann gegebenenfalls mittels eines 
 EMI1.3 
   beträgt, wahrend der   von Porzellan im Mittel 0'000004 ist   (vgl.   Landolt-Börnatein,   Phys.-Chem. Tabellen).   



   PATENTANSPRÜCHE 
1. Vakuumdichte   Elektrodeneinführung   für   Metalldampfgleichrichter,   insbesondere grosser Leistung, dadurch gekennzeichnet, dass der Teil des   Metallgefnsses,   durch den die 
 EMI1.4 
 koeffizienten besitzt wie das die   Eiektrode elektrisch   vom   Metallgeftiss trennende Isolier-   material.

 EMI1.1
 



   In metal vapor rectifiers of high power, the vacuum-tight introduction of the electrodes causes considerable difficulties because it is necessary to use materials that are electrically insulating and that do not expand in any other way than the neighboring parts of the vessels or the electrode, even when heated. A wide variety of combined seals have already been proposed for this Grande. The union of several dissimilar sealing elements results in an intricate design and thereby the increased possibility of malfunctions.



   According to the invention, the part of the vessel wall that comes into contact with the sealing point, i.e. through which the electrode enters, is made from a substance which has the same expansion coefficient as the intermediate material used for electrical insulation of the electrode. For example, the latter can be made of porcelain
 EMI1.2
 



  The nickel steel ring in contact with the porcelain ring is connected to the edge of the housing by welding and the unequal expansion between the nickel steel ring and the housing wall is absorbed by internal stresses, while there is no displacement between the nickel steel ring and the porcelain ring when heated.



  The seal between the porcelain and nickel steel ring can optionally by means of a
 EMI1.3
   is, while that of porcelain is on average 0'000004 (cf. Landolt-Börnatein, Phys.-Chem. Tables).



   PATENT CLAIMS
