Description

Verfahren zur Verringerung des Verlustwinkelanstiegs in mit flüssigen chlorierten bzw. fluorierten aromatischen Kohlenwasserstoffen, vorzugsweise chlorierten Diphenylen, gefüllten elektrischen Geräten . Unter den Isolierflüssigkeiten für elektrische Geräte haben in letzter Zeit chlorierte bzw. fluorierte aromatische Kohlenwasserstoffe Bedeutung erlangt, :die gegenüber Öl den großen Vorteil haben, daß sie unbrennbar sind. Als besonders geeignet erwiesen sich chlorierte Diphenyle mit einem Zusatz von Trichlorbenzol.Method for reducing the increase in loss of angle in liquid chlorinated or fluorinated aromatic hydrocarbons, preferably chlorinated Diphenylene, filled electrical equipment. Among the insulating fluids for Recently, electrical appliances have been chlorinated or aromatic fluorinated Hydrocarbons become important: which have the great advantage over oil, that they are incombustible. Chlorinated diphenyls have proven to be particularly suitable with an addition of trichlorobenzene.

Dabei hat sich gezeigt, daß in die Isolierflüssigkeiteingesetzte Stoffe, z: B. Holz oder das als Baustoff sehr wichtige Kupfer, den Verlustwinkelanstieg der Isolierflüssigkeit ungünstig beeinflussen. Die Ursache ist z. B. bei Kupfer in der katalytis'c'hen Einwirkung des Kupfers auf die Isolierflüssigkeif zu suchen, die die dierektrischen Eigenschaften, insbesondere ,den Verlustwinkel, verschlechtern. Man hat deshalb bereits versucht, die Aufbaustoffe mit einem Anstrich von Acetylcellulose, Schellack oder polymerisierten chlo-Herten Substitutionsprodukten von Vinylacetat zu überziehen oder der Isolierflüssigkeit geringe Mengen von Stabilisatoren zuzusetzen.It has been shown that substances used in the insulating liquid e.g. wood or copper, which is very important as a building material, the increase in the loss angle affect the insulating liquid unfavorably. The cause is z. B. with copper to look for in the catalytic effect of copper on the insulating liquid, which degrade the dielectric properties, in particular the loss angle. Attempts have therefore already been made to paint the building blocks with acetyl cellulose, Shellac or polymerized chlorinated substitution products of vinyl acetate to coat or to add small amounts of stabilizers to the insulating liquid.

Nach der Erfindung erfolgt die Verringerung des Verlustwin kelanstiegs in einer noch einfacheren Weise. Der Baustoff für das Gerät, besonders das isolierte oder blanke Kupfer der Wicklung, wird zunächst mit der Isollerflüssigkeit erhitzt und nach der Abkühlung mit frischer Isolierflüssigkeit ausgewaschen, um die verbrauchte Flüssigkeit völlig zu entfernen. Die Erhitzung des Baustoffes erfolgt zweckmäßig mehrere Stunden bei Wasserbadtemperatur. Während dieser Behandlung verändert sich :die Oberfläche des Baustoffes, z. B. des Kupfers, derart, daß sie keinen weiteren Einfluß auf -den Verlustwinkelanstieg der Isolierflüssigkeit ausübt. Nach dieser Vorbehandlung kann man. den Baustoff, z. B. die Wicklung seines Spannungswandlei in das Gehäuse einsetzen, das mit fn hei' Isolierflüssigkeit der gleichen Art gefül@.`s, r Bei der Behandlung von Kupfer mit eii@ Gemisch von chlorierten Diphenylen und cri-' Chlorbenzol ist es völlig gleichgültig; ob das Kupfer blank oder Papier- bzw. seidenisoliert ist. In jedem Falle wird sich eine bedeutende Verringerung des Verlustwinkelanstiegs ei;nstellen.According to the invention, the increase in the loss angle takes place in an even simpler way. The building material for the device, especially the insulated one or bare copper of the winding, is first heated with the insulating liquid and after cooling, washed out with fresh insulating liquid to remove the used To remove liquid completely. The building material is heated appropriately several hours at water bath temperature. During this treatment changes : the surface of the building material, e.g. B. of copper, such that they none exerts further influence on the increase in the loss angle of the insulating liquid. To you can do this pretreatment. the building material, e.g. B. the winding of his voltage converter insert it into the housing filled with hot insulating liquid of the same type, r When treating copper with a mixture of chlorinated diphenyls and It is completely indifferent to cri- 'chlorobenzene; whether the copper is bare or paper or is silk insulated. In either case, there will be a significant decrease in the rise in loss angle to adjust.
