Description

Elektrode für Erdungen. Bisher wurden zu Erdern für Schutzerdungen Platten, RÖhre, Bänder usw. aus gewöhnlichem oder verzinktem Kupfer und, wo dies zu teuer war, aus verzinktem Eisen hergestellt. Die Verzinkung hatte den Zweck, die Elektroden vor chemischen Angriffen durch die Humussäure des Erdbodens und vor ähnlichen Einflüssen. zu schützen. Bei verzinkten Eisenelektroden, die sehr weitgehend angewendet werden, .macht .sich aber die Tatsache sehr störend bemerkbar, daß Zink und Eisen irrt feuchten Erdreich eine galvanische Zelle bilden, sobald der Zinküberzug das Eisen nicht ganz vollständig bedeckt. Die hierbei auftretenden elektrischen Ströme zerstören aber das Eisen noch schneller, als es ohne die schützende Zink= Schicht der Fall sein würde. Um das Auftreten von solchen Strömen zu vermeiden un'd dennoch billiges Eisenmaterial für die Elektroden verwenden zu können, werden nach der Erfindung Elektroden aus einer Legierung verwendet, die z. B. aus Eisen mit einem Zusatz von 0,3 his o,5 Prozent Kupfer besteht. Elektroden aus diesem Material sind wesentlich :billiger als renne Kupferelektroden und halten den zerstörenden, aus dem Erdreich stammenden Einflü.ssen sehr lange stand.Grounding electrode. Up to now, plates, tubes, tapes, etc. have been made of ordinary or galvanized copper and, where this was too expensive, of galvanized iron for earthing electrodes for protective earthing. The purpose of galvanizing was to protect the electrodes from chemical attack by the humic acid in the soil and from similar influences. to protect. In the case of galvanized iron electrodes, which are widely used, the fact that zinc and iron erroneously form a galvanic cell when the zinc coating does not completely cover the iron becomes very disturbing. The electrical currents that occur here destroy the iron even faster than would be the case without the protective zinc layer. In order to avoid the occurrence of such currents and still be able to use cheap iron material for the electrodes, electrodes made of an alloy are used according to the invention, which z. B. consists of iron with an addition of 0.3 to 0.5 percent copper. Electrodes made of this material are essential: cheaper than running copper electrodes and withstand the destructive influences from the ground for a very long time.
