Description

  Gleichrichter. 



   Der Kathodenbehälter von Eisengleichrichtern muss bekanntlich am Eisengefäss isoliert befestigt sein, weil andernfalls   der Eathodenfleck bzw.   der Lichtbogen leicht am Gehäuse emporwandert und zu Rückzündungen und andern Störungen führt. 



   Der Kathodenbehälter wurde daher bisher stets durch   Zwischenfügen   eines Porzellanringes isoliert. 



  Dieser ist jedoch bei grossen Abmessungen des Porzellanringes nicht mehr genügend betriebssicher, da er sowohl infolge mechanischer Einwirkungen als auch infolge von   Wärmebeanspruchungen   leicht zerspringt. 



   Erfindungsgemäss kann eine sehr sichere Isolierung der Kathode von dem Gefäss dadurch erreicht werden, dass an Stelle eines Porzellankörpers ein oxydierter Metallring verwendet wird. Bekanntlich ist es möglich, auf Aluminium, Magnesium oder deren Legierungen eine Oxydschicht von genügender Haltbarkeit zu erzeugen, die eine Spannung von 100 Volt verträgt. Durch Verwendung mehrerer hintereinandergeschalteter Ringe kann die Betriebssicherheit erhöht werden.

  Rectifier.



   As is well known, the cathode container of iron rectifiers must be attached to the iron vessel in an insulated manner, because otherwise the cathode spot or the arc easily migrates up the housing and leads to reignitions and other faults.



   The cathode container has therefore always been insulated by inserting a porcelain ring between them.



  However, given the large dimensions of the porcelain ring, this is no longer sufficiently operationally reliable, since it easily cracks both as a result of mechanical effects and as a result of thermal stresses.



   According to the invention, very reliable insulation of the cathode from the vessel can be achieved by using an oxidized metal ring instead of a porcelain body. As is well known, it is possible to produce an oxide layer of sufficient durability on aluminum, magnesium or their alloys, which can withstand a voltage of 100 volts. The operational reliability can be increased by using several rings connected in series.
