   FRANZ   PICHLER     ? WEIZ (STEIERMARK).   Kühleinrichtung für Transformatoren und Erregerapulen. 



   Es ist bekannt, dass der Materialaufwand für Wechsel- und Drehstromtransformatoren, sowie auch für die Erregerspulen an   D-namoD1aschinen   und Elektromotoren unmittelbar von der zulässigen Erwärmung derselben abhängt. Der Materialaufwand wird umso kleiner, je geringer   die Wärmeentwicklung   in solchen Apparaten oder je besser die Kühlung derselben ist. Bei Dynamoankern, sowie auch bei sehr   grossen Wechselstrom-     trusfot'atoren,   hat man daher, um Material zu ersparen, zur Kühlung durch mechanische Ventilation gegriffen. 



   Für kleinere   l'ransformatoreu   und Erregerspulen jedoch stellte sich diese Methode bisher zu theuer. Derselbe Zweck   ! ässt   sich aber nun auch durch eine wesentliche Vergrösserung der abkühlenden Oberfläche ohne künstliche Ventilation erreichen. Eine solche 
 EMI1.1 
 strömen mindestens an einer Stelle radial geschlitzt sein, können aber auch, wie in Fig. 2 der beiliegenden Zeichnung ersichtlich, aus zwei oder mehreren Theilen bestehen. Ausserdem kann man bei Transformatoren, bei denen auch im Eisenkerne Wärme entwickelt wird.   die Küh ! ptatten an der inneren Seite derart aufbiegen oder auftreiben, dass sie zwischen Spule und Kern den letzteren\umschliessen und die im Kerne erzeugte Wärme nach aussen   leiten, ohne dass dieselbe die Spule zu durchdringen hat.

   FRANZ PICHLER? WHEAT (STEIERMARK). Cooling device for transformers and exciter batteries.



   It is known that the cost of materials for AC and three-phase transformers, as well as for the excitation coils on D-namoD1maschinen and electric motors, depends directly on the permissible heating of the same. The cost of materials becomes smaller, the lower the heat development in such apparatus or the better the cooling of the same. With dynamo armatures, as well as with very large alternating current trusphot'ators, one has therefore resorted to mechanical ventilation to save material.



   For smaller transformers and excitation coils, however, this method has so far been too expensive. Same purpose! However, it can now also be achieved by significantly increasing the cooling surface without artificial ventilation. Such

 flow are radially slotted at least at one point, but can also consist of two or more parts, as can be seen in FIG. You can also use transformers in which heat is developed in the iron core. the cow! Bend or force ptatten open on the inner side in such a way that they enclose the latter between the coil and the core and conduct the heat generated in the core to the outside without it having to penetrate the coil.



   Fig. 1 of the accompanying drawings shows a single-phase AC transformer equipped with such a cooling device, half in view, half
