Description

Die Erfindung betrifft einen elektrischen Lkhtbogengleich- und -wechselrichter, dessen Elektroden in atmosphärischer Umgebung ohne Druckverminderung arbeiten. Um dies zu ermöglichen, bringt die Erfindung eine für die erstrebten Zwecke besonders vorteilhafte Auswahl unter den Elektrodenmaterialien, und zwar soll die !Cathode vorwiegend aus Kobaltoxyd bzw. Oxydul bestehen. Es ist an sich bekannt, zur Erzielung einer Raumladung in einem Durchschlagraum glühende Körper mit Oxydbelag zu verwenden, . was aber die Zwecke der Erfindung nicht erfüllt. Es ist dadurch lediglich dargetan, daß durch dieThe invention relates to an electrical arc rectifier and inverter, the Electrodes work in an atmospheric environment without reducing the pressure. To make this possible, the invention brings a for the intended purposes particularly advantageous selection among the electrode materials, and the cathode is supposed to consist mainly of cobalt oxide or oxide. It is in itself known to achieve a space charge in a breakdown space with glowing bodies To use oxide covering. but this does not meet the purpose of the invention. It is thereby merely demonstrated that by the

t5 Verwendung von Oxyden, radioaktiven Stoffen o. dgl. die Entladung gefördert wird. Die durch die Erfindung unter den Metalloxyden getroffene Auswahl hat, wie Versuche unter Anwendung von Kohleanoden ergeben haben, die besondere Folge, daß der Gleichrichtereffekt ein verhältnismäßig sehr hoher wird, d.h. daß im Mittel Wirkungsgrade von etwa 850/0 erreicht werden unter den an sich günstigen äußeren Bedingungen der freien atmosphärischen Umgebung der Elektroden ohne Druckverminderung.t 5 Use of oxides, radioactive substances or the like. The discharge is promoted. The selection made by the invention among the metal oxides has, as tests using carbon anodes have shown, the particular consequence that the rectifier effect is relatively very high, ie that on average efficiencies of about 850/0 are achieved among the favorable ones external conditions of the free atmospheric environment of the electrodes without pressure reduction.

Die Anode kann statt aus Kohle auch aus anderen entsprechend wirkenden Stoffen bestehen. Die Wirkung des Gleich- bzw. Wechselrichters kann noch durch die an sich be- ,30 kannte Beifügung von radioaktiven Substanzen zum Kathodenmaterial erhöht werden.Instead of carbon, the anode can also consist of other substances with a corresponding effect. The effect of the rectifier or inverter can also be determined by the per se, 30 known addition of radioactive substances to the cathode material can be increased.
