Description

Transformator mit Blechkern Bei Transformatoren, insbesondere kleinen Transformatoren, wie sie für Rundfunk, Verstärker und Beleuchtungszwecke verwendet werden, wird nach der vorliegenden Erfindung eine wesentliche Vereinfachung, Verbesserung und auch Verbilligung dadurch erzielt, daß die Blechkerne nicht durch Preßplatten und Bolzen, deren Anordnung die Herstellungsweise erschwert, zusammengefügt und gepreßt werden, sondern die Blechpakete in eine im -Arbeitszustand des Transformators starre und feste Masse eingebettet werden, so daß alle Vibrationen der Bleche beim Arbeiten des Transformators unmöglich sind. Die Massen werden dadurch widerstandsfähig und stabil gegen die Kraftwirkung des Eisenkerns, daß man ihnen festes Material in Pulvetform zusetzt, am besten Quarz, Quarzsand oder Asbest. Man verhindert durch derartige wärmeleitende Massen gleichzeitig, daß in dem Transformator Wärmestauungen auftreten.Transformer with sheet metal core For transformers, especially small ones Transformers such as those used for broadcasting, amplifiers, and lighting purposes becomes, according to the present invention, a substantial simplification, improvement and also achieved cheaper that the sheet metal cores are not by pressing plates and bolts, the arrangement of which complicates the manufacturing process, joined together and are pressed, but the laminated core in a working state of the transformer rigid and solid mass are embedded, so that all vibrations of the metal sheets when Working of the transformer are impossible. This makes the masses resilient and stable against the force of the iron core, making them solid material in powder form, preferably quartz, quartz sand or asbestos. One prevents by such thermally conductive masses at the same time that heat build-up in the transformer appear.

Die Abbildung zeigt eine Ausführung eines Transformators nach der vorliegenden Erfindung. Der Eisenkern K wird ohne jede Verfestigungs- und Spannvorrichtung in das mit z. B. Quarzkompoundmasse gefüllte Gehäuse g eingebettet. Durch Distanzstäbe d werden Kurzschlüsse der Eisenbleche an den Wänden des Gehäuses verhindert. Die Masse ist bei einer Temperatur von ioo bis 13o° flüssig, wird in das Gehäuse hineingegossen und erstarrt hier, den Transformator fest umklammernd. Das Brummen eines derartig behandelten 5o-Perioden-Transformators ist wesentlich geringer, als wenn der Kern desselben Transformators fest in eine Preßvorrichtung eingespannt worden wäre. Die Quarz- und Sandfüllung der Kompoundmasse macht diese wärmeleitend, so daß Wärmestauungen im Innern des Transformators nicht auftreten können.The figure shows a version of a transformer according to the present invention. The iron core K is made without any strengthening and tensioning device in that with z. B. quartz compound filled housing embedded g. By spacer bars d short circuits of the iron sheets on the walls of the housing are prevented. the The mass is liquid at a temperature of 100 to 130 ° C and is poured into the housing and freezes here, clutching the transformer tightly. The hum of such a thing treated 5o-period transformer is much less than if the core of the same transformer would have been firmly clamped in a pressing device. the Quartz and sand filling of the compound make it thermally conductive, so that heat build-up cannot occur inside the transformer.
