Description

Elektrischer Apparat, insbesondere Transformator Das Patent 9r6 o8r betrifft einen elektrischen Apparat, insbesondere einen Transformator, der mit einem chlorierten Diphenyl als Isolierflüssigkeit gefüllt ist und bei .dem die blanken oder isolierten Leiter, deren Leiterwerkstoff eine katalytische Wirkung auf chloriertes Diphenyl ausübt (insbesondere Kupfer), mit Schellack überzogen sind.Electrical apparatus, in particular a transformer The patent 9r6 o8r relates to an electrical apparatus, in particular a transformer, which is connected to a chlorinated diphenyl is filled as insulating liquid and with .dem the bare or insulated conductors whose conductor material has a catalytic effect on chlorinated Diphenyl wields (especially copper), are coated with shellac.

Eine vorteilhafte Verbesserung des Gegenstandes des Patents 9i6 o81 wird gemäß der zusätzlichen Erfindung dadurch erzielt, daß der Schellacküberzug vor seiner Verwendung einem Backprozeß unterworfen wird. Hierdurch erweist sich der Schellack auch hohen Betriebstemperaturen gegen-Über als widerstandsfähig.A beneficial improvement on the subject matter of patent 9i6 o81 is achieved according to the additional invention in that the shellac coating is subjected to a baking process prior to its use. This proves it The shellac is also resistant to high operating temperatures.

Der Backpro.zeß wird vorteilhafterweise bei einer Temperatur von etwa 13o bis 1q.0° C vorgenommen, während die Backzeit zweckmäßigerweise 3 bis 5 Stunden beträgt.The baking process is advantageously carried out at a temperature of about 13o to 1q.0 ° C made, while the baking time is expediently 3 to 5 hours amounts to.

Es ist an sich möglich, den Backprozeß bei längeren Backzeiten durchzuführen, jedoch können hierdurch einerseits die Überzüge spröde werden und zeigen andererseits das Bestreben, sich von dem Werkstoff loszulösen.It is actually possible to carry out the baking process with longer baking times, however can as a result, on the one hand, the coatings become brittle and on the other hand, they show a tendency to detach themselves from the material.
