Description

Verfahren zur Isolierung von Transformator- und Dynamoblechen Die zum Bau von Transformatoren erforderlichen Bleche bedürfen bekanntlich einer Isolierung gegen elektrische Spannungen.Process for the insulation of transformer and dynamo sheets The Sheets required for the construction of transformers are known to require insulation against electrical voltages.

Man verwendete hierzu bisher eine Papierbeklebung der Bleche oder aber eine dünne Isolierschicht auf den Blechen, die aus einer Mischung von Wasserglas, aufgeschlossener Kartoffelstärke und Farbkörpern besteht. Die Haltbarkeit einer so hergestellten Isolierungsmasse ist jedoch durch eine in kurzer Zeit eintretende Zersetzung bzw. Säuerung in Frage gestellt. Eine sich dadurch ergebende Neuherstellung der Isoliermasse bzw. Neuisolierung der Bleche erfordert nicht geringe Kosten.For this purpose, up to now a paper pasting of the sheets or has been used but a thin layer of insulation on the metal sheets, made of a mixture of water glass, opened potato starch and color bodies. The durability of a The insulation compound produced in this way is, however, due to a occurring in a short time Decomposition or acidification called into question. A resulting new manufacture the insulation compound or new insulation of the sheets does not require low costs.

Erfindungsgemäß läßt sich eine Isolierung auf einfachste Weise dadurch herstellen, daß die Bleche mit einer Isoliermasse überzogen werden, die ein in einer Cellulosederivatquellung eingebettetes Magnesiumsilicat enthält. Das in der Natur vorkommende Magnesiumsilicat [NIg3 Hz (S'03)411 auch Talkum oder Speckstein genannt, wird in feinster Schlemmung in eine Cellulosederivatquellung eingebracht. Die sich hieraus ergebende Isoliermasse bleibt satzfrei, unbegrenzt haltbar, lagerfähig und stets gebrauchsfertig.According to the invention, insulation can thereby be achieved in the simplest possible manner produce that the sheets are coated with an insulating compound that is one in one Cellulose derivative swell contains embedded magnesium silicate. That in nature Occurring magnesium silicate [NIg3 Hz (S'03) 411 also called talc or soapstone, is brought into a cellulose derivative swelling in the finest slurry. Which The resulting insulating compound remains set-free, has an unlimited shelf life, can be stored and always ready to use.

Nach dem Überziehen der Bleche bildet sich ein porenfreier, fester, elastischer Film, der nicht hygroskopisch ist und mit dem eingebetteten Magnesiumsilicat fest auf dem Metall haftet.After coating the sheet, a pore-free, solid, elastic film which is not hygroscopic and with the embedded magnesium silicate firmly adheres to the metal.
