Description
Einrichtung zur Sicherung des Zusammenpressens der Wicklungsspulen von Transformatoren und ähnlichen Apparaten. Die Erfahrung hat gelehrt, daß die Wicklungsspulen von Öltransformatoren und ähnlichen Apparaten nach ihrem Kochen im Öle oder nach mehr oder weniger langem Gebrauche sich setzen oder näher zusammenrücken, so daß es nötig wird, Nachschau zuhalten und die Spannglieder nachzuziehen.Device for securing the compression of the winding coils transformers and similar devices. Experience has shown that the Winding coils of oil transformers and similar apparatus after their boiling sit down or move closer together in the oil or after more or less long use, so that it is necessary to look after and retighten the tendons.
Die Erfindung vermeidet diesen Nachteil. Gemäß derselben wird das Zusammenpressen der Wicklungsspulen von Transformatoren und ähnlichen Apparaten dadurch gesichert, daß der Eisenkörper des Transformators oder ähnlicher Apparate mit oder ohne Zuhilfenahme von Federn frei hängend mit seinem ganzen Gewichte die Wicklungsspulen belastet, um- sie dauernd in achsialer Richtung zusammenzupressen.The invention avoids this disadvantage. According to the same it will Compression of the winding coils of transformers and similar devices secured by the fact that the iron body of the transformer or similar apparatus with or without the aid of springs hanging freely with all its weights Winding coils are loaded in order to keep them pressed together in the axial direction.
Dabei können im Falle der Verwendung von Federn diese so angeordnet werden, daß ihre Spannung sich zur Gewichtsbelastung des Eisenkör p--rs hinzugesellt.In the case of using springs, these can be arranged in this way that their tension is added to the weight load on the iron body.
Die Abb. i, 2 und 3 der Zeichnung veranschaulichen zwei Ausführungsbeispiele des Erfindungsgegenstandes bei Öltransformatoren. In beiden Fällen ist a der Eisenkörper, b und c bezeichnen die beiden Wicklungen, deren Spulen übereinanderliegen und auf dem Untersatz d aufruhen. Der Eisenkörper a hängt frei und ruht mittels oberer Seitenflanschen e auf den Wicklungsspulen auf, so daß er dieselben mit seinem ganzen Gewichte belastet und sie dadurch fest zusammenpreßt. Bei der Ausführungsform gemäß Abb. i und-2 wird die Gewichtsbelastung des Eisenkörpers auf die Wicklungsspulen durch Zwischenfedern f übertragen, die zwischen die Seitenflanschen e und den oberen Preßrahmen g eingeschaltet sind.Figs. I, 2 and 3 of the drawing illustrate two embodiments of the subject of the invention in oil transformers. In both cases, a is the iron body, b and c designate the two windings, the coils of which lie one above the other and rest on the base d. The iron body a hangs freely and rests on the winding coils by means of upper side flanges e, so that it loads them with all of its weight and thereby presses them tightly together. In the embodiment according to FIGS. I and 2, the weight load of the iron body is transmitted to the winding coils by intermediate springs f which are connected between the side flanges e and the upper press frame g.
Beim Beispiel der Abb. 3 unterstützen die Federn f das Belastungsgewicht des Eisenkörpers a, dessen Seitenflanschen e unmittelbar auf den Wicklungsspulen aufruhen. Die gespannten Federn f sind nämlich an festen Lagerschienen abgestützt und drücken auf die am unteren Teil des Eisenkörpers befestigten Seitenflanschen el, so daß ihre Spannung sich -zur Gewichtsbelastung des Eisenkörpers hinzugesellt.In the example of Fig. 3, the springs f support the loading weight of the iron body a, whose side flanges e directly on the winding spools riot. The tensioned springs f are namely supported on fixed bearing rails and press on the side flanges attached to the lower part of the iron body el, so that their tension is added to the weight of the iron body.
