  Einrichtung zum Kühlen von   Tran8formatorwicklungen   und Magnetspulen elektrischer
Maschinen. 



   Die Transformator- und Magnetspulen elektrischer Maschinen werden   ! her häufig   geteilt, um durch die derart bewirkte   Vergrösserung   der Wärme abgebenden   Oberfläche eine   wirksame Kühlung und somit Verminderung der Temperaturzllnahme der Wicklung der Spulen zu erreichen. Die die Wärme ableitende Oberfläche kann auch nach einer anderen bekannten   Ausführung   (vergl. österr. Patent Nr. 8508) dadurch vergrössert werden, dass zwischen den 
 EMI1.1 
 rand vorragen. 



   Diese Konstruktion hat den Nachteil, dass das teuere Material der zur Wärmeableitung dienenden Platten für elektrische Zwecke nicht   ausgenützt     word. un   dass die Platten von den Wicklungen sehr sorgfältig isoliert werden müssen,   wodurch die Wärmeabgabe der Wicklung   an die Platten sehr behindert ist. 



   Durch die Einrichtung nach vorliegender Erfindung werden diese Nachteile dadurch vermieden, dass mehrere Windungen dei Wicklung-bei Transformatoren der   Sekundärwicklum ;   - aus hochkant angeordnetem Flachkupferhand gebildet werden, das so breit gewählt wird. dass es über den Rand der äusseren Mantelfläche der Wicklung vorragt und derart die   Wärme   leicht nach aussen abführt. 



   In der Zeichnung sind mehrere   Ausführungsformen   des Erfindungsgegenstandes dargestellt.
Fig. 1 und 2 veranschaulichen einen   Drebstromtransformator teilweise   in Ansicht und 
 EMI1.2 
 vorliegender Erfindung, und
Fig. 3 und 4 zeigen der Erfindung gemäss konstruierte Magnetspulen. 



   Der in Fig   1 und   2 veranschaulichte Drehstromtransformator besitzt in üblicher Weise   ausgefiihrte Spulen a für   die Primärwicklung und Spulen b für die aus Flachkupferband hergestellte Sekundärwicklung. Jede Spule b der   Sekundärwicklung besitzt   mehrere Windungen c von solcher Breite, dass diese den Rand der Spulen überragen und derart die Wärme leicht an die Luft abgeben können. Diese Windungen können auch geschlitzt und die so gebildeten Zähne   d   aufgebogen sein, um die Wärmeabgabe an die Luft zu erleichtern. 



   Bei   Magnetspulenf nüt   einer Wicklung aus Flaehkupferband kann, wie Fig. 3 veranschaulicht die beschriebene Einrichtung ohne Änderung angewendet werden. 



   Fig. 4 zeigt eine Ma, gnetspule q mit einer Wicklung aus isoliertem Runddraht, zwischen deren Windungen mehrere Windungen h aus hochkant angeordnetem Flachkupferband untergebracht sind. die den Rand der Spule überragen und eine wirksame Kühlung bewirken.

  Device for cooling transformer windings and magnetic coils electrical
Machinery.



   The transformer and magnet coils of electrical machines are! Often divided here in order to achieve effective cooling and thus a reduction in the temperature increase of the winding of the coils through the enlargement of the heat-emitting surface brought about in this way. The heat-dissipating surface can also be enlarged according to another known design (see Austrian Patent No. 8508) in that between the
 EMI1.1
 protrude edge.



   This construction has the disadvantage that the expensive material of the plates serving for heat dissipation is not used for electrical purposes. and that the plates must be very carefully isolated from the windings, as a result of which the heat transfer from the winding to the plates is very difficult.



   The device according to the present invention avoids these disadvantages in that several turns of the winding — in transformers the secondary winding; - Formed from edgewise arranged flat copper hand, which is chosen as wide. that it protrudes over the edge of the outer jacket surface of the winding and thus easily dissipates the heat to the outside.



   Several embodiments of the subject matter of the invention are shown in the drawing.
Fig. 1 and 2 illustrate a three-phase transformer partially in view and
 EMI1.2
 present invention, and
3 and 4 show magnet coils constructed in accordance with the invention.



   The three-phase transformer illustrated in FIGS. 1 and 2 has coils a for the primary winding and coils b for the secondary winding made from flat copper strip in the usual manner. Each coil b of the secondary winding has several turns c of such a width that they protrude beyond the edge of the coils and thus can easily give off the heat to the air. These turns can also be slotted and the teeth d thus formed can be bent up in order to facilitate the dissipation of heat into the air.



   In the case of magnetic coils with a winding made of flat copper strip, the device described can be used without modification, as FIG. 3 illustrates.



   4 shows a magnetic coil q with a winding made of insulated round wire, between the turns of which several turns h made of flat copper strip arranged on edge are accommodated. which protrude beyond the edge of the coil and cause effective cooling.
