Description

Kathodenisolator für Metalldampfgleichrichter Der Kathodenbehälter von Eisengleichrichtern muß bekanntlich am Eisengefäß isoliert befestigt sein, andernfalls der Kathodenfleck bzw. der Lichtbogen leicht am Gehäuse emporwandert und zu Rückzündungen und anderen Störungen führt.Cathode insulator for metal vapor rectifiers The cathode container of iron rectifiers must, as is well known, be attached to the iron vessel in an insulated manner, otherwise the cathode spot or the arc easily migrates up the housing and causes reignition and other disturbances.

Der Kathodenbehälter wurde daher bisher meistens durchZwischenfügen einesPorzellanringes 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.The cathode container has therefore hitherto mostly been interposed a porcelain ring isolated. However, this is with large dimensions of the porcelain ring no longer sufficiently operationally reliable, as it is due to mechanical influences and easily cracks due to thermal stress.

Erfindungsgemäß wird an der Oberfläche oxydiertes Aluminium, Magnesium oder eine Legierung aus diesen Metallen als Kathoden-Isolator für Metalldampfgleichrichter verwendet. Bekanntlich ist es möglich, auf Aluminium, Magnesium oder deren Legierungen eine Oxydschicht von genügender Haltbarkeit zu erzeugen, die eine Spannung von iooVolt verträgt. Durch Verwendung mehrerer hintereinandergeschalteter Ringe kann die Betriebssicherheit erhöht werden.According to the invention, aluminum, magnesium, is oxidized on the surface or an alloy of these metals as a cathode insulator for metal vapor rectifiers used. As is well known, it is possible to use aluminum, magnesium or their alloys to produce an oxide layer of sufficient durability, which has a voltage of iooVolt tolerates. By using several rings connected in series, the operational safety increase.
