  Belastungsspule. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Spulen mit vollständig oder nahezu symmetrischen Hauptwicklungen und der erfindungsgemässen Saugwicklung oder dem Saugmantel besitzen die Eigenschaft, dass die elektrischen Daten der Spule unverändert bleiben, wenn die Spule in die gebräuchliche metallene Schutzkappe gelegt wird. Die Spulen eines Satzes können auch ohne Kappen beliebig aufeinander oder nebeneinander gelegt werden, ohne dass die Nebensprechwerte dabei eine Veränderung erfahren. 



   PATENT-ANSPRÜCHE :
1. Belastungsspule für Pupinleitungen, dadurch gekennzeichnet, dass unmittelbar auf dem Kern eine mit den   Pupinwicklungen   in keiner leitenden Verbindung stehende   Hilfswickdung   angebracht ist, zum Zwecke, das Auftreten von Streufeldern durch die in der Hilfswicklung fliessenden induzierten Ströme zu verhindern.

   Coils with completely or almost symmetrical main windings and the suction winding according to the invention or the suction jacket have the property that the electrical data of the coil remain unchanged when the coil is placed in the customary metal protective cap. The coils of a set can also be placed on top of or next to each other without caps, without the crosstalk values being changed.



   PATENT CLAIMS:
1. Load coil for Pupin leads, characterized in that an auxiliary winding which is not in a conductive connection with the Pupin windings is attached directly to the core, for the purpose of preventing the occurrence of stray fields from the induced currents flowing in the auxiliary winding.

Claims (1)

2. Belastungsspule nach Anspruch 1, dadurch gekennzeichnet, dass die Hilfswicklung aus einer Anzahl parallel geschalteter Wicklungsabschnitte besteht, deren Wicklungsanfäl1ge und ebenso deren Wicklungsenden für sich miteinander verbunden sind. 2. Load coil according to claim 1, characterized in that the auxiliary winding consists of a number of winding sections connected in parallel, the winding starts and ends of which are connected to one another. 3. Belastungsspule nach Anspruch 1, dadurch gekennzeichnet, dass die Hilfswicklung aus einem Mantel aus gut leitendem Material ; vorzugsweise Kupfer, besteht, der senkrecht zur Richtung der in ihm induzierten Ströme geschlitzt ist. EMI2.1 3. load coil according to claim 1, characterized in that the auxiliary winding consists of a jacket made of highly conductive material; preferably copper, which is slotted perpendicular to the direction of the currents induced in it.
