Description

  

  Elektrische Spule.    Gegenstand vorliegender Erfindung be  trifft elektrische Spulen mit hintereinander  geschalteten Wicklungen, die auf einem ge  meinsamen Kern übereinander liegen und aus  Drähten von verschiedener Stärke bestehen.  Es war bis jetzt bei derartigen Spulen üblich,  die Wicklungen aus dickerem Draht an den       Spulenkern    und die dünneren Drähte um jene  Wicklung zu legen. Da nun bekanntlich ein  dünnerer Draht bei Stromdurchgang sich  stärker erwärmt als ein in Serie mit jenem  Draht geschalteter dickerer Draht, so voll  zieht sich die Wärmeabgabe jener Spulen  langsamer an den als Kühlfläche wirkenden       Spulenkern,    als wenn :die .dünneren, stärker  erwärmten Drähte nächst dem     Spulenkern     liegen würden.  



  Gemäss vorliegender Erfindung liegen  nun die Wicklungen aus dünnerem Draht  ,dem     Spulenkern    näher als :die Wicklungen  aus dickerem Draht, die ersteren liegen also         zunächst    dem     Spulenkern.    Durch diese An  ordnung der Wicklungen wird eine ganz we  sentliche Verminderung der Erwärmung der  Spule bei Stromdurchgang erreicht.



  Electric coil. The subject matter of the present invention applies to electrical coils with series-connected windings which are superimposed on a common core and consist of wires of different thicknesses. It has heretofore been customary in such coils to have the thicker wire windings attached to the core and the thinner wires around that winding. Since, as is well known, a thinner wire heats up more strongly when a current passes through it than a thicker wire connected in series with that wire, the heat emission of those coils is drawn more slowly to the coil core acting as a cooling surface than if: the thinner, more strongly heated wires next to the Coil core would lie.



  According to the present invention, the windings made of thinner wire are closer to the coil core than: the windings made of thicker wire, so the former are first of all the coil core. With this arrangement of the windings, a very substantial reduction in the heating of the coil when the current passes through is achieved.

PATRNTANSPRUCII Elektrische Spule mit auf einem gemein samen Kern übereinander angeordneten, hin tereinander geschalteten Wicklungen aus Drähten von verschieden grossem Durchmes ser, dadurch gekennzeichnet, dass die Wick lungen aus dünnerem, bei Stromdurchgang sich stärker erwärmendem Draht dem Eisen kern näher liegen als die Wicklungen aus dickerem Draht, zum Zwecke, die Wärmeab gabe der dünneren Drähte an den als Kühl fläche wirkenden Spulenkern zu befördern und die Erwärmung der Spule zu vermin lern. PATRNTANSPRUCII Electric coil with coils made of wires of different diameters and arranged one above the other on a common core, characterized in that the windings made of thinner wire that heats up more when current is passed are closer to the iron core than the windings made of thicker wire Wire, for the purpose of conveying the heat output of the thinner wires to the coil core acting as a cooling surface and to learn the heating of the coil to vermin.
