Description

Den Gegenstand der Erfindung bildet eine Anordnung, Wechsel- oder Drehstrom in eine andere Spannung zu transformieren. Dazu bedient man sich eines Transformators oder Umspanners.The subject of the invention forms an arrangement, exchange or Transform three-phase current into another voltage. One uses one for this Transformer or transformer.

Es sind derartige Einrichtungen bekannt, wonach man auf einen geschlossenen Eisenkern zwei voneinander getrennte Wicklungen anbringt und somit transformiert. Es ist daher nicht gleichgültig, wie man diese getrennten Wicklungen auf diesen Eisenkern anbringt, um ein gutes induktives Koppelverhältnis herzustellen.Such devices are known, after which one is closed Iron core attaches two separate windings and thus transforms them. It is therefore not a matter of indifference how to put these separate windings on these Iron core attaches to produce a good inductive coupling ratio.

Die bekannten Einrichtungen weisen Kern- oder Mantelanordnung der Eisen- und Spulensätze auf. Die Eisenbleche eines solchen Transformators werden gestanzt und zum Mantel oder Kern zusammengeschachtelt. Diese Aufbauweise erfordert sehr viel Arbeit. Wickelkerne aus Blechband sind in dieser Hinsicht günstiger, ergeben aber einen ungünstigen Spulenaufbau.The known devices have core or shell arrangement of the Iron and coil sets on. The iron sheets of such a transformer will be punched and nested together to form a shell or core. This construction requires a lot of work. Winding cores made of sheet metal strip are more favorable in this respect, given but an unfavorable coil structure.

Der Erfindungsgegenstand zeigt gegenüber den bekannten Anordnungen einen völlig anderen Aufbau der Eisenbleche sowie der Anordnung der Spulensätze auf. Der Eisenkern ist ebenfalls von einem Blechband aufgewickelt, jedoch zu einem Ringkerntransformator so, daß die koaxial zum Rollkern liegenden Spulen völlig vom Eisen Unischlossen sind. Die Spulenanordnung bei diesem Transformator ist demnach sehr einfach. Da der Kern E gemäß der Zeichnung rund ist, kann man denselben in einer einfachen Drehbank: bequem aufwickeln. Die Spule selbst ist mit ihrer Wicklung unterteilt in Si und S2, die untereinanderliegen. Daraus ergibt sich ein günstiges induktives Koppelverhältnis. Dazu kommt noch, daß die Spulen vollkommen in dem Eisenkern eingeschlossen liegen in bezug auf die Streuwirkung der Spulen selbst. So ist das magnetische Feld der Spulen S, und S, völlig geschlossen und ein guter 'Wirkungsgrad garantiert durch die verlustarme Anordnung. Die Stromwärmeverluste werden durch die Luftkanäl; A und A i abgeführt. Dieser Transformator kann daher auch mit Luft oder Öl gekühlt werden.The subject of the invention shows a completely different structure of the iron sheets and the arrangement of the coil sets compared to the known arrangements. The iron core is also wound from a sheet metal strip, but into a toroidal core transformer in such a way that the coils lying coaxially to the roll core are completely enclosed by the iron. The coil arrangement in this transformer is therefore very simple. Since the core E is round as shown in the drawing, it can be wound up comfortably in a simple lathe. The winding itself is divided into Si and S2, which are one below the other. This results in a favorable inductive coupling ratio. In addition, the coils are completely enclosed in the iron core with regard to the scattering effect of the coils themselves. The magnetic field of the coils S 1 and S 1 is completely closed and a good degree of efficiency is guaranteed by the low-loss arrangement. The electricity heat losses are through the air ducts; A and A i discharged. This transformer can therefore also be cooled with air or oil.
