  Einleiterstremtransformator. 



   Die Erfindung bezieht sich auf eine Befestigungsvorrichtung   für Einleiterstrom-   trausformatoren, die eine grosse achsiale Länge aufweisen. Die Befestigung derartiger Transformatoren bereitete inseferne Schwierigkeiten, als die bisher verwendeten Tragschellen die Wicklung des Ringkernes leicht zerdrücken konnten. Die Tragkonstruktionen, die diesen Nachteil vermeiden sollten, waren dagegen ziemlich kompliziert. 



   Gemäss der Erfindung werden diese Nachteile dadurch vermieden, dass in den'Eisenkern mit Vorsprüngen versehene Metallteile eingelagert und mittels durchgehender Holzen mit den Kernblechen zu einem festen Körper vereint sind. Mittels der Vorsprünge wird der Transformator an den Tragschienen befestigt. 



   Auf der Zeichnung ist als Ausflihrungsbeispiel ein mit der neuen Befestigungsvorrichtung versehener Transformator in Fig. 1 in Seitenansicht. in Fig. 2 im Schnitt dar- 
 EMI1.1 
 gezeichnet. 



   Den Primärleiter p des Transformators umgibt ein   Isolierzylinder i,   der einen zylindrischen, mit der   Sekundärwicklung   s versehenen Eisenkern e trägt. Dieser Eisenkern besteht in bekannter Weise aus aufeinander geschichteten, kreisringförmigen Blechen. 



  Zwischen diesen Blechen sind zwei eiserne Platten   t1.   t2 eingelagert. Sie bestehen (Fig. 3) im wesentlichen aus einem geteilten Kreisring   des glochen Querschnittes   wie die Eisenbleche. besitzen jedoch Vorsprünge   v.   die mit Löchern zum Befestigen versehen sind. 



  Werden diese Tragteile aus unmagnetischem Material hergestellt. 80 konnen sie auch zu 
 EMI1.2 
 an einem der beiden Enden befestigen. 



   Nach dem Zusammenpacken sind die Bleche und Tragkörper mittels durchgehender Schraubenbolzen b zu einem einheitlichen   Korper zusammengepresst.   Auf diesem ist die Wicklung   8   aufgebracht. wobei die   Vorsprünge der Tragkörper frei   gelassen sind. In den aus der Wickelung herausragenden \'orsprüngen sind Löcher o vorgesehen. Mittels durch diese hindurchgesteckter Schraubenbolzen q wird die Befestigungsvorrichtung und damit der Transformator an zwei   Flachschienen fangebracht.

  Single-line transformer.



   The invention relates to a fastening device for single-conductor current transformers which have a large axial length. The attachment of such transformers caused far-reaching difficulties when the previously used support clamps could easily crush the winding of the toroidal core. On the other hand, the supporting structures that were supposed to avoid this disadvantage were rather complicated.



   According to the invention, these disadvantages are avoided in that metal parts provided with projections are stored in the iron core and united with the core sheets to form a solid body by means of continuous wood. The transformer is attached to the mounting rails by means of the projections.



   In the drawing, a transformer provided with the new fastening device is shown in side view in FIG. 1 as an exemplary embodiment. in Fig. 2 in section
 EMI1.1
 drawn.



   The primary conductor p of the transformer is surrounded by an insulating cylinder i which carries a cylindrical iron core e provided with the secondary winding s. This iron core consists, in a known manner, of annular sheets stacked on top of one another.



  Between these sheets are two iron plates t1. t2 stored. They consist (Fig. 3) essentially of a divided circular ring of the same cross-section as the iron sheets. however, have projections v. which are provided with holes for fastening.



  Are these supporting parts made of non-magnetic material. 80 you can too
 EMI1.2
 attach at one of the two ends.



   After they have been packed together, the metal sheets and supporting bodies are pressed together to form a uniform body by means of continuous screw bolts b. The winding 8 is applied to this. wherein the projections of the support bodies are left free. Holes o are provided in the projections protruding from the winding. The fastening device and thus the transformer are attached to two flat rails by means of screw bolts q inserted through them.
