Description

  

   <Desc/Clms Page number 1> 
 



  Vorrichtung zum Verspannen von Transformatoreisenkörpern 
Die Erfindung bezieht sich auf eine Vorrichtung zum Verspannen von Transformatoreisenkörpern unter Benutzung von Jochpresstraversen und vorgebogenen Schenkelpressplatten, deren maximale Durchbiegung aus der Gleichung 
 EMI1.1 
 
 EMI1.2 
 

 <Desc/Clms Page number 2> 

 



   Der Erfindungsgegenstand ist in der Zeichnung beispielsweise veranschaulicht. 



   Mit 1 ist ein Transformatorschenkel, mit 2 ein Transformatorjoch und mit 3 eine Schenkelpressplatte bezeichnet. Letztere wird nach Art einer geraden Biegefeder vorgespannt. Dasselbe gilt auch für die Jochpresstraversen 4,5, welche man mittels der Schrauben 6 zusammenzieht. Die Presselemente 8 dienen zur Pressung der nicht gezeigten Wicklungen. An den unteren und oberen Jochpresstraversen sind Bolzen 10 angeschweisst, die in Löcher 9 der Schenkelpressplatten 3 eingreifen, welche sich auf diese Weise mit den Jochpresstraversen verankern lassen und somit gleichzeitig als Zugstangen dienen, mit denen Axial kräfte der Wicklungen aufgenommen werden können. Durch die Löcher 9'werden Schrauben geführt, welche dazu dienen, die Schenkelpressplatten zusammenzuhalten, wenn die oberen   Jochpresstraversen5   zum Zwecke der Wicklungsmontage abgenommen sind.

   Schliesslich werden noch Bügel 12 und 13 sowie hierin eingeschraubte Presselemente 11 vorgesehen. Die unteren Bügel 12 übernehmen gleichzeitig die Funktion eines Abstützträgers des Transformatorkörpers und ergeben die notwendige Standfläche. Die Breite b sowie die Höhe h der Schenkelpressplatte 3 können der Zeichnung entnommen werden. Unter der Einspannlänge   1e   ist die Strecke zwischen dem oberen Rand der unteren Presstraverse 4 und dem unteren   Randder   oberen Presstraverse 5 zu verstehen. Die Länge 1 des Kerns entspricht in   üblicher Weise der Höhe   des Transformatorfensters. 



   Sofern bei besonders langen Schenkelpressplatten deren mechanische Vorspannung zur gleichmässigen   Pressung des Blechpaketes nicht ausreichen   sollte, könnten selbstverständlich auch einige wenige bekannte Bolzen bzw. Bandagen Verwendung finden.

  Device for clamping transformer iron bodies
The invention relates to a device for tensioning transformer iron bodies using yoke press traverses and pre-bent leg press plates, the maximum deflection of which from the equation
 EMI1.1
 
 EMI1.2
 

 <Desc / Clms Page number 2>

 



   The subject matter of the invention is illustrated in the drawing, for example.



   1 with a transformer leg, 2 with a transformer yoke and 3 with a leg press plate. The latter is pretensioned like a straight spiral spring. The same also applies to the yoke press traverses 4, 5, which are pulled together by means of the screws 6. The pressing elements 8 are used to press the windings, not shown. Bolts 10 are welded to the lower and upper yoke traverses, which engage in holes 9 of the leg press plates 3, which can be anchored in this way with the yoke traverses and thus also serve as tie rods with which axial forces of the windings can be absorbed. Screws are passed through the holes 9 ', which serve to hold the leg press plates together when the upper yoke press traverses 5 are removed for the purpose of winding assembly.

   Finally, brackets 12 and 13 and press elements 11 screwed into them are also provided. The lower bracket 12 simultaneously take on the function of a support beam of the transformer body and provide the necessary floor space. The width b and the height h of the leg press plate 3 can be seen in the drawing. The clamping length 1e is to be understood as the distance between the upper edge of the lower press crossbeam 4 and the lower edge of the upper press crossbeam 5. The length 1 of the core corresponds in the usual way to the height of the transformer window.



   If, in the case of particularly long leg press plates, the mechanical pre-tensioning thereof should not be sufficient for uniform pressing of the laminated core, a few known bolts or bandages could of course also be used.
