  Transformator. 



   Eiserne Pressbolzen, die die Schenkel und Joche von Transformatoren in Richtung der Schenkel- aehsen zusammenpressen, werden in der Nähe der Stossfugen vom Joch und Schenkel leicht durch Streu- kraftlinien erhitzt. Um diesen Übelstand zu vermeiden, hat man vorgeschlagen, die Bolzen aus Messing zu machen. Dies kann aber wegen seiner geringeren Festigkeit nicht als vollwertiger Ersatz angesehen werden und verteuert ausserdem den Transformator erheblich. Nun sind aber in dem sogenannten unmagnctischen Eisen und unmagnetischen Stahl-das sind Nickel-Eisen-Legierungen mit hohem Nickel- gehalt, die eine sehr niedrige Permeabilität besitzen-Stoffe bekannt, die die mechanischen Eigenschaften   des Eisens, aber nicht die in diesem Falle unerwünschten magnetischen Eigenschaften besitzen.

   Gegenstand   der Erfindung ist es, die durch Streukraftlinien   gefährdeten   Pressbolzen aus unmagnetischem Eisen oder unmagnetischem Stahl herzustellen. Man erhält so dieselbe Festigkeit wie bei den bisher benutzten
Bolzen aus gewöhnlichem Eisen und vermeidet deren Nachteile. 



   In der Zeichnung ist ein   Ausführungsbeispiel   der Erfindung dargestellt. Die Joche a, die stumpf auf die Schenkel b aufgelegt sind, werden mit diesen durch die Bolzen c zusammengehalten. An den
Berührungsstellen zwischen Joch und Schenkeln zeigen die Kraftlinien Neigung, in die Bolzen   nberzu-   treten, falls diese aus gewöhnlichem Eisen sind. Dies wird dadurch vermieden, dass gemäss der Erfindung die Bolzen aus unmagnetischem Eisen bestehen.

  Transformer.



   Iron compression bolts, which press the legs and yokes of transformers together in the direction of the leg axes, are slightly heated in the vicinity of the butt joints of the yoke and legs by lines of scattering force. To avoid this inconvenience, it has been proposed to make the bolts from brass. However, because of its lower strength, this cannot be regarded as a full-fledged replacement and also makes the transformer considerably more expensive. But in so-called non-magnetic iron and non-magnetic steel - these are nickel-iron alloys with a high nickel content and very low permeability - substances are known that have the mechanical properties of iron, but not the magnetic properties that are undesirable in this case Possess properties.

   The object of the invention is to produce the extrusion bolts, which are at risk from lines of stray force, from non-magnetic iron or non-magnetic steel. The same strength is obtained as with the previously used
Bolts made of ordinary iron and avoids their disadvantages.



   An exemplary embodiment of the invention is shown in the drawing. The yokes a, which are butted onto the legs b, are held together with them by the bolts c. To the
The points of contact between the yoke and the legs show the lines of force a tendency to step into the bolts, if these are made of ordinary iron. This is avoided in that, according to the invention, the bolts are made of non-magnetic iron.
