Description

Verfahren zur Verbesserung des Wirkungsgrades von Hochfrequenztransformatoren. Die Erfindung betrifft eine Ausführungsform des Verfahrens nach dem Hauptpatent. Bei diesem wird der Wirkungsgrad von Hochfrequenztransformatoren dadurch verbessert und .die Herausfilterung der Vielfachen der Grundfrequenz dadurch ermöglicht, daß die Transformatorenkerne aus dünnem, isoliertem Eisendraht von höchstens o,i mm Durchmesser gewickelt werden.Process for improving the efficiency of high-frequency transformers. The invention relates to an embodiment of the method according to the main patent. This improves the efficiency of high-frequency transformers and .the filtering out of the multiples of the fundamental frequency in that the transformer cores made of thin, insulated iron wire of no more than 0.1 mm Diameter to be wound.

Der vorliegenden Erfindung liegt .d:e Erkenntnis zugrunde, daß man in gewissen Fällen, insbesondere dann, wenn die Isolation aus einer Emaillierung besteht, den gleichen bzw. annähernd - gleichen Effekt auch dadurch erzielen kann, daß man statt rundem Draht von dem für ,den betreffenden Fall gewünschten geringen Durchmesser auch Draht verwenden kann, der als runder Draht einen größeren Durchmesser hat, der aber dann zu einem flachen Band von der gewünschten Stärke ausgewalzt wird. Das heißt also, braucht .man einen Durchmesser von o,i mm; so kann man auch Draht von 0,i5 bis o,3 mm benutzen, der aber auf etwa 0,03 mm flach gewalzt wird, wobei das dünne Band eine Breite von etwa i mm annimmt. Der Vorteil besteht darin, daß bei der Weiterverarbeitung eines so dünnen Haardrahtes ,die Gefahr des Reißens verringert ist und das Emaillieren leichter vor sich geht.The present invention is based on the knowledge that in certain cases, especially when the insulation consists of enamelling, the same or approximately the same effect can also be achieved by using instead of round wire the one for, The small diameter desired in the case in question can also use wire which, as a round wire, has a larger diameter, but which is then rolled out into a flat strip of the desired thickness. That means, you need a diameter of 0.1 mm; so you can also use wire from 0.15 to 0.3 mm, but it is rolled flat to about 0.03 mm, with the thin strip assuming a width of about i mm. The advantage is that when processing such a thin hair wire, the risk of tearing is reduced and enamelling is easier.
