Description

  

   <Desc/Clms Page number 1> 
 



  Primärwicklung für einen   Niederspannungstransformator   mit ringförmigem magnetischen Kreis 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 insbesondere für Stromwandler,bindungsklemme ist in jedem dieser Löcher fest verankert. Mit 8 ist der magnetische Kreis des Transformators bezeichnet, der mit der Sekundärwicklung ausgestattet ist. 



   Die beschriebene Primärwicklung wird an dem magnetischen Kreis in folgender Weise angebracht :
Die Wicklung mit den in den Vertiefungen verankerten Klemmen wird-wie es die Fig. 2 und 3 zeigen-zunächst dem magnetischen Kreis entgegengestellt, d. h. der mittlere Teil der Primärwicklung befindet sich in einer annähernd zur Achse des magnetischen Kreises parallelen Ebene. Die Enden 2 und 3 der Primärwicklung werden sodann, wie die Fig. 5 und   o   zeigen, in das zentrale Fenster des magnetischen Kreises 8 hineingestossen. Dann verdreht man den magnetischen Kreis um 900 relativ zur-Primärwicklung (oder   umgekehrt) - s. Fig. 7 -in   der Weise, dass zwei diametral entgegengesetzte Sektoren des magnetischen Kreises in das Innere der gefalteten Teile 9 (Fig. 4) der Bandenden 2 und 3 eindringen.

   Die Primärwicklung ist sodann endgültig am magnetischen Kreis aufgebracht, und man erhält ein Gebilde, wie es in den Fig. 8,9 und 10 dargestellt ist. 



   Der Transformator kann dadurch vervollständigt werden, dass entweder der magnetische Kreis zur Gänze   im Inneren   zweier aufeinanderliegender Schalen aus Isoliermaterial untergebracht oder dass er ins Innere einer Form gebracht und dort mit Isoliermaterial zur Gänze umhüllt wird. 



   Das Metallstück, das die Primärwicklung bildet, ist aus einem einzigen Stück. gefertigt, was den Vorteil mit sich bringt, dass'ein unmittelbarer Kontakt mit Leitungen oder Sammelschienen hergestellt werden kann, ohne dass Klemmen, Lötungen usw. erforderlich wären. 



   Die Erfindung ermöglicht also einerseits die Herstellung einer Primärwicklung für Stromwandler ohne Löten od. dgL und anderseits ein leichtes und billiges Anbringen derselben am Transformator, wobei der direkte Kontakt mit den äusseren Leitungen gesichert ist.

  Primary winding for a low voltage transformer with an annular magnetic circuit
 EMI1.1
 

 <Desc / Clms Page number 2>

 Especially for current transformers, the binding clamp is firmly anchored in each of these holes. With 8 the magnetic circuit of the transformer is referred to, which is equipped with the secondary winding.



   The primary winding described is attached to the magnetic circuit in the following way:
As shown in FIGS. 2 and 3, the winding with the clamps anchored in the depressions is initially opposed to the magnetic circuit; H. the middle part of the primary winding is in a plane approximately parallel to the axis of the magnetic circuit. The ends 2 and 3 of the primary winding are then pushed into the central window of the magnetic circuit 8, as FIGS. 5 and o show. Then you turn the magnetic circuit by 900 relative to the primary winding (or vice versa) - s. 7 - in such a way that two diametrically opposed sectors of the magnetic circuit penetrate inside the folded parts 9 (FIG. 4) of the tape ends 2 and 3.

   The primary winding is then finally applied to the magnetic circuit, and a structure is obtained as shown in FIGS. 8, 9 and 10.



   The transformer can be completed in that either the magnetic circuit is completely housed in the interior of two superimposed shells made of insulating material or it is brought into the interior of a mold and there is completely covered with insulating material.



   The piece of metal that forms the primary winding is made from a single piece. manufactured, which has the advantage that direct contact with lines or busbars can be made without terminals, soldering, etc. being required.



   The invention thus enables on the one hand the production of a primary winding for current transformers without soldering or the like and on the other hand an easy and cheap attachment of the same to the transformer, the direct contact with the external lines being ensured.
