Die vorliegende Erfindung betrifft einen elektrischen Umformer jener Art, bei welchem die Primär- und Secundä'rspulen in einander angeordnet sind und durch aus einzelnen Blechplatten zusammengesetzte Eisenrahmen hindurchtreten. Bei Umformern dieser Art kann die in der Masse der Spulen erzeugte Wärme, besonders wenn es sich um grofse Umformer handelt und wenn eine Spule zwischen zwei anderen Spulen liegt, nicht genügend vollständig abgeführt werden, so dafs häufig die Isolation beschädigt und die Wirkung des Umformers verringert wird.The present invention relates to an electrical converter of the type in which the Primary and secondary coils are arranged in one another and pass through iron frames composed of individual sheet metal plates. With converters of this kind, the heat generated in the bulk of the coils, especially when it is large converters and if a bobbin lies between two other bobbins, it is not sufficiently complete dissipated, so that the insulation and the effectiveness of the converter are often damaged is decreased.
Um diesen Uebelstand zu vermeiden, hat man den Spulen in einigen Fällen solche. Durchmesser gegeben, dafs zwischen ihnen vollständige Lufträume vorhanden waren, allein diese Anordnung hat den Nachtheil, dafs sie die wirksame Regelung des Umformers vermindert.In order to avoid this inconvenience, these are used in the coils in some cases. Diameter given that there were complete air spaces between them, alone this arrangement has the disadvantage that it reduces the effective control of the converter.
Nach der vorliegenden Erfindung werden diese Uebelstände dadurch vermieden, dafs eine oder mehrere der Spulen an den Theilen, welche zwischen den aus Blechen zusammengesetzten Rahmen des Kernes liegen, in der Weise von den benachbarten Spulen abgebogen werden, dafs Ventilationskanäle gebildet werden, welche rechtwinklig zu den Windungsebenen der Spulen liegen und durch welche Luft oder ein anderes kühlendes Medium hindurchgeschickt werden kann, um die Wärme fortzunehmen und das Innere der Spulen zu kühlen, ohne dafs hierdurch die wirksame Regelung des Umformers irgendwie beeinträchtigt würde. Die Erfindung kann an verschiedenen Arten von elektrischen Umformern der angegebenen Art benutzt werden.According to the present invention, these inconveniences are avoided by the fact that a or several of the coils on the parts which are between those composed of sheets Frame of the core, bent away from the neighboring coils in such a way that ventilation channels are formed, which are at right angles to the winding planes of the coils and through which air or another cooling medium is sent through can be used to remove the heat and cool the interior of the coils, without thereby being effective Control of the converter would be affected somehow. The invention can be applied to various Types of electrical converters of the type specified are used.
Auf der Zeichnung ist im Horizontalschnitt ein elektrischer Umformer dargestellt, dessen Primärspule ρ concentrisch zwischen zwei Secundärspulen s angeordnet ist, wobei alle Spulen durch aus Blechplatten zusammengesetzte Rahmen α hindurchtreten, die von dem mittleren Theil des Umformers radial nach aufsen gehen, wie dies in den englischen Patentschriften 2801 und 9457/1897 beschrieben ist. Bei dem dargestellten Beispiel ist jede der beiden Secundärspulen s an den Theilen, welche zwischen den aus einzelnen Blechplatten zusammengesetzten Rahmen α liegen, mit Ausbiegungen b versehen, welche von der Primärspule ρ abgewendet sind, so dafs dadurch verticale Kanäle c gebildet werden, welche rechtwinklig zur Windungsebene der Spulen liegen und welche gestatten, dafs Luft oder ein anderes kühlendes Medium zwischen die benachbarten Spulen hindurchfliefst und die Hitze aus dem Innern der mit einander verbundenen Spulen fortführt.In the drawing, an electrical converter is shown in horizontal section, the primary coil ρ of which is arranged concentrically between two secondary coils s , with all coils passing through frames α composed of sheet metal plates, which extend radially outwards from the central part of the converter, as in the English Patent Specifications 2801 and 9457/1897 is described. In the example shown, each of the two secondary coils s is provided with bends b on the parts which lie between the frames α , which are composed of individual sheet metal plates, which are turned away from the primary coil ρ , so that vertical channels c are thereby formed which are at right angles to the The winding plane of the coils and which allow air or some other cooling medium to flow between the adjacent coils and to carry the heat away from the interior of the coils connected to one another.
Es ist klar, dafs durch Anordnung der Ausbuchtungen b zwischen den aus einzelnen Blechplatten zusammengesetzten Rahmen a des Kernes nicht verhindert wird, dafs die Spulen möglichst dicht an die wirksamen Theile herangebracht werden, nämlich die Theile, wo die Spulen von den Rahmen umfafst werden, so dafs die Bildung der Luftkanäle c die wirk-It is clear that the arrangement of the bulges b between the frame a of the core, which is composed of individual sheet metal plates, does not prevent the coils from being brought as close as possible to the active parts, namely the parts where the coils are surrounded by the frame, so that the formation of the air ducts c is the effective
same Regelung des Umformers nicht beeinträchtigt. ·same control of the converter is not affected. ·
Bei Umformern, welche mit sehr vielen aus einzelnen Blechen zusammengesetzten Rahmen a versehen sind, erhalten die Secundärspulen zweckmäfsigerweise eine Wellenform, wie auf der Zeichnung dargestellt.In converters which are provided with a large number of frames a composed of individual metal sheets, the secondary coils are expediently given a wave shape, as shown in the drawing.
