Description

  

  Kathodenisolator.    Die Herstellung grosser Kathodenisolato  ren aus keramischem Material ist schwierig.  Man hat daher derartige Isolatoren aus Seg  menten zusammengesetzt, die einander über  lappen oder sich unmittelbar an den Kanten  berühren, was genaue Schleifarbeit und einen  Ring zum Zusammenhalten benötigt.  



  Gemäss vorliegender Erfindung, die sich  auf aus Isolationsplatten zusammengesetzte  Kathodenisolatoren für Grossgleichrichter be  zieht, werden die einzelnen Platten durch  elektrisch     isolierendeZwischenstücke    gehalten.  



  Die beiliegende Zeichnung zeigt schema  tisch zwei Ausführungsbeispiele des Erfin  dungsgegenstandes. Beim Beispiel     Fig.    1  setzt sich der Kathodenisolator aus ebenen  Platten 1 zusammen, die durch elektrisch  isolierende Zwischenstücke 2 zusammenge  halten werden. Beim Beispiel     Fig.    2 sind  gekrümmte Platten verwendet. Je nach Wahl    und Zusammensetzung der Platten lassen sich  so beliebige, dem Zweck angepasste Quer  schnitte für Kathodenisolatoren formen.



  Cathode insulator. The production of large cathode isolators made of ceramic material is difficult. One has therefore composed such insulators from Seg ments that overlap each other or touch directly on the edges, which requires precise grinding work and a ring to hold together.



  According to the present invention, which relates to cathode insulators for large rectifiers composed of insulation plates, the individual plates are held by electrically insulating spacers.



  The accompanying drawing shows schematically two exemplary embodiments of the subject matter of the invention. In the example of Fig. 1, the cathode insulator is composed of flat plates 1, which are held together by electrically insulating spacers 2. In the example of Fig. 2, curved plates are used. Depending on the choice and composition of the plates, any desired cross-sections for cathode insulators can be formed.
