Description

Verfahren zur Tränkung der Isolation von Hochspannungskabeln Es ist bekannt, daß Öle, welche längere Zeit dem Sauerstoffe der, -Luft ausgesetzt sind, sauer werden und Schlamm absetzen. Besonders stark hat sich diese Erscheinung bei Öltransformatoren bemerkbar gemacht, welche häufig viele Jahre hindurch nicht geöffnet werden und bei denen das Öl oft beträchtliche Erwärmungen erleidet. Um diese Veränderung der Isolieröle zu vermeiden, wurde vorgeschlagen, den Sauerstoff der Luft durch ein sogenanntes Ausdehnungsgefäß auszuschalten oder den Transformator oben mit Stickstoff zu füllen oder auch das Öl vor dem Einfüllen durch eine ininige Berührung mit einem indifferenten Gase zu desoxydieren.Process for impregnating the insulation of high voltage cables It is known that oils which are exposed to the oxygen in the air for a longer period of time get acidic and settle mud. This phenomenon has been particularly strong Oil transformers made noticeable, which often did not open for many years and in which the oil often suffers considerable warming. About this change To avoid the insulating oils, it has been suggested to pass the oxygen in the air turn off a so-called expansion tank or put the transformer on top with nitrogen to fill or the oil before filling by a close contact with one to deoxidize inert gases.

Bei .elektrischen Isolierölen für ähnliche Zwecke, welche aber während des Betriebes, d. h. in erwärmtem -Zustande, dem Luftsauerstoffe und damit also dem Altern nicht ausgesetzt sind, hat man solche Maßnahmen bisher nicht angewandt, insbesondere nicht bei dem Imprägnierverfahren für Hochspannungskabel. - Man hatte hier um so weniger Bedenken betreffs der Oxydation des Öles oder des Gemisches von Ölen und Harzen, weil diese Massen während des Verfahrens durch Hinzufügen frischen Materials dauernd verjüngt werden. Es ist zwar bekannt, daß bei Hochspannungskabeln die Tränkmassen schon während der kurzen Zeit des Gebrauches stark oxydieren und daß hierdurch größere Verluste im Dielektrikum des Kabels verursacht werden können. Dies sollte durch besondere Zusatzstoffe zu dem Isoliermaterial vermieden werden.With .electric insulating oils for similar purposes, but which during of the company, d. H. in a heated state, the atmospheric oxygen and thus are not exposed to aging, such measures have not yet been used, especially not with the impregnation process for high-voltage cables. - One had here all the less concern about the oxidation of the oil or mixture of Oils and resins because these masses are fresh by adding them during the procedure Material are continuously rejuvenated. It is known that in high voltage cables the impregnation masses oxidize strongly even during the short period of use and that this can cause greater losses in the dielectric of the cable. This should be avoided by adding special additives to the insulating material.

In - Abweichung hiervon wird gemäß. der Erfindung vorgeschlagen, die Öle oder Mischungen von Ölen während der ganzen Dauer des Imprägnierverfahrens in geschlossenen Gefäßen unter einem inerten Gase, vorzüglich Stickstoff, zu halten.In deviation from this, according to. proposed the invention, the Oils or mixtures of oils throughout the impregnation process in Keep closed vessels under an inert gas, especially nitrogen.
