Description
Anodenkörper für den elektrischen Korrosionsschutz mit Kabelanschluß und Verfahren zu seiner Herstellung Es ist bekannt, für Zwecke des elektrischen Korrosionsschutzes entweder galvanische Anoden aus Magnesium, Zink, Aluminium od. dgl. oder für die Einspeisung fremden Gleichstromes in den Stromkreis bestimmte Anoden aus Graphit, Eisen oder anderem leitendem Material zu verwenden. In diesen bekannten Anordnungen sind die Anodenkörper über eine Kabelverbindung ohne oder mit Zwischenschaltung von Gleichrichtern und anderen Schaltelementen mit dem zu schützenden Objekt verbunden. Hierbei ist die Verbindungsstelle des Kabels mit dem Anodenkörper besonders korrosionsgefährdet. Diese Stelle muß daher unter allen Umständen vor dem Zutritt von Feuchtigkeit geschützt werden, welche als Elektrolyt eine Korrosion verursachen könnte. Die bekannten Ausführungen solcher Anoden sehen meist Verbindungen mit Stopfbuchsen und anderen Dichtungen aus Gummi in der von Feuchtrauminstallationen her bekannten Art vor. Bei den metallischen Anoden ist es auch üblich, die Leitungsanschlüsse mit dem Anodenkörper zu verlöten oder zu verschweißen oder in den Metallkörper einzugießen und die Verbindungsstelle nachträglich durch Anstriche bzw. Kitte verschiedener Art zu isolieren.Anode body for electrical corrosion protection with cable connection and method of its manufacture It is known for purposes of electrical Corrosion protection either galvanic anodes made of magnesium, zinc, aluminum or. Like. Or intended for feeding external direct current into the circuit To use anodes made of graphite, iron or other conductive material. In these known arrangements are the anode body via a cable connection without or with the interconnection of rectifiers and other switching elements with the to protective object connected. Here is the connection point of the cable with the Anode body particularly at risk of corrosion. This body must therefore under all circumstances be protected from the ingress of moisture, which as an electrolyte causes corrosion could cause. The known designs of such anodes mostly see connections with stuffing boxes and other rubber seals in damp-proof installations known type before. In the case of the metallic anodes, it is also common to use the line connections to be soldered or welded to the anode body or poured into the metal body and the connection point subsequently with different paints or putties Kind of isolate.
Es sind ferner Anodenkörper für den elektrischen Korrosionsschutz mit Anschlußbolzen bekannt, wobei der Bolzen in eine Aussparung des Anodenkörpers eingelassen ist, welche mit dem darin befindlichen Bolzen und dem daran angeschlossenen Kabelende mit einer feuchtigkeitsbeständigen Vergußmasse ausgefüllt ist. Die Erfindung besteht nun darin, daß bei an sich bekannter Verwendung von Graphit als Anodenmaterial und von Gießharz als Vergußmasse außer der Aussparung selbst auch die Poren in einem der Aussparung benachbarten Bereich des Graphitkörpers mit Gießharz ausgefüllt sind. Diese Ausführung ist unabhängig von Art und Form der verwendeten Anoden. Die Anschlüsse können auch auf der Montagestelle mit den für Gießharz-Kabelverbindungen und -Endverschlüsse üblichen Mitteln hergestellt werden. Dadurch wird der Anschluß beliebig langer Zuleitungen ermöglicht.There are also anode bodies for electrical corrosion protection known with connecting bolt, the bolt in a recess in the anode body is let in, which with the bolt located therein and the attached to it Cable end is filled with a moisture-resistant potting compound. The invention consists in the fact that with a known use of graphite as anode material and of casting resin as a casting compound, in addition to the recess itself, the pores in one the area of the graphite body adjacent to the recess is filled with casting resin. This design is independent of the type and shape of the anodes used. The connections can also be used on the installation site with the for cast resin cable connections and terminations usual means. This makes the connection of cables of any length enables.
Auf diese Weise wird die Anwendung von Graphitanoden erst praktisch möglich gemacht, da mit Sicherheit ein Vordringen von Flüssigkeit zu der Berührungsfläche Anodenkörper-Anschlußbolzen unterbunden wird, und zwar auch ein Vordringen von Flüssigkeit durch das Anodenmaterial selbst. Ferner wird als weiterer Vorteil eine Verbesserung der mechanischen Festigkeit des porösen Anodenmaterials durch das eingedrungene Gießharz erzielt, die ein Ausbrechen der Öffnung im Graphitkörper beim Einfügen des Anschlußbolzens, insbesondere wenn dieser schraubbar befestigbar ist, verhindert. Bei Anoden mit langgestreckter Form ist der Anodenkörper vorteilhafterweise an beiden Enden mit Anschlüssen versehen.This is how the use of graphite anodes becomes practical made possible, as there is certainly a penetration of liquid to the contact surface Anode body connecting bolt is prevented, and also an ingress of liquid by the anode material itself. Furthermore, an improvement becomes an additional advantage the mechanical strength of the porous anode material due to the penetrated Cast resin achieved, which breaks out the opening in the graphite body when inserting of the connecting bolt, especially if it can be screwed on, prevented. In the case of anodes with an elongated shape, the anode body is advantageously on both Provide ends with connections.
Zur Herstellung eines Anodenkörpers nach der Erfindung wird vorzugsweise so verfahren, daß der Graphitkörper mit einer Bohrung versehen, Gießharz in diese Bohrung hineingepreßt, der Preßdruck eine Zeitlang, z. B. 1/z Stunde, aufrechterhalten und nach dem Erhärten des Gießharzes dieses durch erneutes Bohren an der alten Stelle aus der Bohrung wieder entfernt wird, worauf der Anschlußbolzen mit dem Kabelende in dieser Bohrung versenkt befestigt und der fr.,gi gebliebene Raum der Bohrung erneut mit Gießharz ausgefüllt wird.To produce an anode body according to the invention, it is preferred proceed in such a way that the graphite body is provided with a hole, casting resin in this Bore pressed in, the pressure for a while, z. B. 1 / z hour and after the casting resin has hardened, drill it again at the old location is removed from the hole again, whereupon the connecting bolt with the cable end fastened sunk in this hole and the remaining space of the hole is filled again with casting resin.
Anodenkörper der beschriebenen Art können natürlich auch für verwandte Zwecke benutzt werden, z. B. in Wasserenteisenungsanlagen und für ähnliche Prozesse, bei denen elektrolytische Wirkungen eine Rolle spielen und das Material der Stromzuführungsanschlüsse dem Angriff eines Elektrolyten ausgesetzt wären, wenn sie nicht besonders geschützt sind.Anode bodies of the type described can of course also be used for related Purposes are used, e.g. B. in water de-ironing plants and for similar processes, in which electrolytic effects play a role and the material of the power supply connections would be exposed to the attack of an electrolyte if not specially protected are.
