Description

Drosselspule ohne Eisenkern Die Belastbarkeit von Drosselspulen ist durch die Erwärmung der Spulenleiter bedingt. Da die Leiter von dem Streufluß der Drosselspule selbst durchdrungen werden, so entstehen außer den normalen. Kupferverlusten, die dem Betriebsstrom der Drosselspule entsprechen, noch Wirbelströme, die die Erwärmung der Drosselspule erhöhen. Mit Rücksicht auf diese Wirbelströme muß die Ausnutzung der Leiterquerschnitte herabgesetzt werden. Besonders unangenehm macht 'sich der Einfluß des Streuflusses mehrphasiger Starkstromdrosselspulen bemerkbar, bei denen die einzelnen Phasen übereinander angeordnet sind.Choke coil without iron core The load capacity of choke coils is due to the heating of the coil conductors. Since the ladder is affected by the leakage flux of the Choke coil itself are penetrated, so arise besides the normal. Copper losses, which correspond to the operating current of the choke coil, nor eddy currents which cause the heating the choke coil increase. With regard to these eddy currents, the utilization the conductor cross-sections are reduced. It makes itself particularly uncomfortable Influence of the leakage flux of multiphase high-voltage choke coils noticeable in which the individual phases are arranged one above the other.

Durch die Erfindung sollen die schädlichen Einwirkungen des Eigenstreufeldes von Drosselspulen verringert werden. Erfindungsgemäß werden bei Drosselspulen zwischen den einzelnen Windungen der Spulen Leitbleche aus magnetisierbarem Material zwecks Verhinderung der radialen Durchstreuung der Drasselspulenleiter angeordnet. Durch die Einfügung derartiger Leitbleche aus gut magnetisierbarem Material zwischen den Windungen oder den Teilleitern der Windungen wird eine magnetische Führung aller Streufelder beim Durchtritt durch die Wicklungsteile erzwungen und die Durchstreuung der Leiter in radialer Richtung verhindert. Die durch'die Radialstreuung hervorgerufenen Wirbelstromverluste werden durch die Erfindung fast vollständig vermieden. Zugleich werden die durch die Axialfelder entstehenden Wirbelströme in Folge der Zusammenziehung des Magnetflusses in die magnetisierbaren Blechstreifen erheblich verringert.The invention is intended to reduce the harmful effects of the self-scattering field reduced by choke coils. According to the invention in choke coils between the individual turns of the coils for the purpose of baffles made of magnetizable material Prevention of radial scattering of the Drasselspulenleiter arranged. By the insertion of such baffles made of easily magnetizable material between the Windings or the partial conductors of the windings is a magnetic guide of all Stray fields forced through the winding parts and the scattering prevents the conductor in the radial direction. The caused by the radial scattering Eddy current losses are almost completely avoided by the invention. Simultaneously are the eddy currents created by the axial fields as a result of the contraction the magnetic flux in the magnetizable sheet metal strips is significantly reduced.

Es sei bemerkt, daß bei Transformatoren bereits besondere Leitbleche zwischen der Oberspannungs- und der Niederspannungswicklung bzw,, dem Kern und den Wicklungen angeordnet worden sind. Die Leitbleche dienten jedoch bei den bekannten Anordnungen entweder dazu, die Streuung der Transformatoren zu vergrößern oder die Ungleichmäßigkeiten des Streufeldes gegenüber den Wicklungen des Transformatbrs, welche mit Anzapfungen versehen waren, auszugleichen. Durch die bekannte Anordnung der Leitbleche bei Transformatoren wurde aber eine Verringerung der radialen Durchstreuung der Leiter nicht bezweckt und auch nicht erzielt..It should be noted that transformers already have special baffles between the high-voltage and the low-voltage winding or ,, the core and the Windings have been arranged. However, the baffles were used in the known Arrangements either to increase the spread of the transformers or the Irregularities of the stray field compared to the windings of the transformer, which were provided with taps to compensate. Due to the well-known arrangement of the baffles on transformers, however, was a reduction in radial scattering the leader neither aims nor achieves ..

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt.Two exemplary embodiments of the invention are shown in the drawing.

Fig. i zeigt eine Drosselspule mit Scheibenwicklung. Mit i ist die Drosselspule bezeichnet. Zwischen den spiralförmig gewundenen Leitern a dieser Drosselspule (s. Fig. a) sind die zur Leitung der Streufelder vorgesehenen Leitbleche 3 angeordnet. Wie in der Fig. a zu erkennen ist, liegen die Leitbleche auf der einen Seite direkt an den spannungsführenden Leitern 2 an, während sie auf der gegenüberliegenden Seite von der nächsten Windung durch eine Isolationszwischenlage q. getrennt sind.Fig. I shows a choke coil with disc winding. With i is the Indicated choke coil. Between the spirally wound conductors a of this reactor The guide plates 3 provided for guiding the stray fields are arranged (see Fig. a). As can be seen in Fig. A, the baffles are on one side directly to the live Ladders 2 on while they are on the opposite Side of the next turn through an interlayer insulation q. are separated.

Fig. 3 zeigt eine zylinderförmige Drosselspule 5, deren Windungen schraubenförmig übereinandergewickelt sind, so daB sie einen zylinderförmigen Spulenkörper bilden. Die Windungen der Spule sind in dieser Figur mit 6 bezeichnet. 7 bedeutet Isolationszwischenlagen zwischen den einzelnen Windungen, 8 die magnetisierbaren Leitbleche, die etwa einen Z-förmigen Querschnitt besitzen.Fig. 3 shows a cylindrical choke coil 5, its turns are helically wound one above the other, so that they form a cylindrical bobbin form. The turns of the coil are denoted by 6 in this figure. 7 means Isolation layers between the individual turns, 8 the magnetizable Baffles that have an approximately Z-shaped cross-section.

Die Form der Leitbleche kann natürlich gemäß den Anforderungen des Betriebes verändert werden. Beispielsweise können die Leitbleche auch so ausgebildet sein, daß ihre Höhe größer ist als die der Leiter, zwischen denen sie angeordnet sind. ° Die Erfindung bezieht sich auf Drosselspulen ohne Eisenkern zur Strombegrenzung für Zwecke der Stärkstromtechnik.The shape of the baffles can of course according to the requirements of the Operation can be changed. For example, the guide plates can also be designed in this way be that their height is greater than that of the ladder between which they are arranged are. ° The invention relates to inductors without an iron core to limit the current for the purpose of high current technology.
