  Kern für Mehrphasen-, insbesondere Dreiphasentransformatoren 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    stehen.bleche   4 ragen einzeln oder in Gruppen wechselweise über die Enden der Säulen hervor. Das Joch besteht aus einem bandförmigen Transformatorblech 5, das an den Stellen der hervorragenden Säulenbleche entsprechend ausgenommen ist. Um die Zonen der Quermagnetisierung möglichst zu verringern, können nach Fig. 7 die bekannten   Schrägschnitte   angewendet werden. 



   In dem Ausführungsbeispiel Fig. 8 bestehen die Joche aus einzelnen Blechen 6, die sich nur von einer Säule bis zur zweitnächsten erstrecken. Auch hier kann durch Schrägschnitte, wie etwa in Fig. 9 dargestellt ist, der Bereich der Quermagnetisierung verringert werden.

 <Desc / Clms Page number 2>

    Stand.bleche 4 protrude individually or in groups alternately over the ends of the columns. The yoke consists of a strip-shaped transformer sheet 5, which is correspondingly excluded at the points of the outstanding pillar sheets. In order to reduce the zones of transverse magnetization as much as possible, the known bevel cuts can be used according to FIG. 7.



   In the exemplary embodiment in FIG. 8, the yokes consist of individual metal sheets 6, which only extend from one column to the next. Here, too, the area of transverse magnetization can be reduced by means of bevel cuts, for example as shown in FIG. 9.

Claims (1)

PATENTANSPRUCH : Kern für Mehrphasen-, insbesondere Dreiphasentransformatoren mit auf einem polygonalen Grundriss angeordneten Säulen (2u, 2v, 2w) und in sich geschlossenen Jochen (1), wobei die SÅaulen- und Jochbleche an den Vereinigungsstellen überlappt angeordnet sind, dadurch gekennzeichnet, dass die Dicke der Säulen in Richtung des Jochumfanges gemessen grösser als in radialer Richtung ist (Fig. 4, Fig. 5). PATENT CLAIM: Core for multi-phase, especially three-phase transformers with columns (2u, 2v, 2w) arranged on a polygonal plan and self-contained yokes (1), the column and yoke sheets being arranged overlapping at the points of union, characterized in that the thickness of the Columns measured in the direction of the yoke circumference is larger than in the radial direction (Fig. 4, Fig. 5).
