Description

Zur Erdschlußkompensation - werden Drossel--spulen mit Eisenkernen verwandt, deren einer mit der Wicklung versehener Schenkel unter Zwischenschaltung von Luftspalten in einzelne Pakete aufgeteilt ist. Zwecks Einstellung :der gewünschten Induktivität hat man entweder die Luftspalte veränderlich gemacht oder die Wilcklung mit Anzapfungen versehen. Beides ist umständlich und teuer.For earth fault compensation - reactors with iron cores are used related, one of which is provided with the winding leg with the interposition is divided into individual packages by air gaps. For the purpose of setting: the desired Inductance has either made the air gap variable or the winding provided with taps. Both are cumbersome and expensive.

Aufgabe der Erfindung ist es, eine einflachere und billigere Erdschlußdros:selspule zu schaffen. Sie betrifft eine Erdschlußdrosselspule mit zweischenkligem Eisenkern, der längs der Wicklung aus Eisenpaketen und Luftspalten besteht. Erfindungsgemäß sind ein oder mehrere Eisenpakete durch Gleichstrom vormagnetisiert, daß in jedem vormagnetisierten Eisenpaket in sich :geschlossene Flußpfade vorhanden sind.The object of the invention is to provide a flatter and cheaper Erdschlussdros: selspule to accomplish. It concerns an earth-fault reactor with a two-legged iron core, which consists of iron stacks and air gaps along the winding. According to the invention are one or more iron packets biased by direct current that in each premagnetized iron packet in itself: closed flux paths are present.

In Fig. i der Zeichnung ist eine Ausführungsform der Erdschlußdrosselspule gemäß der Erfindung dargestellt. i bezeichnet den Eisenkern und 2 die Wicklung. Der mittlere Teil :des einen Schenkels besteht aus ,drei Eisenpaketen 3 und vier Luftspalten. Zwischen dem nicht unterteilten Teil -des Eisenkernes i und den angrenzenden Eisenpaketen 3 und ferner zwischen je zwei Eisenpaketen befindet sich ein Luftspalt.In Fig. I of the drawings is an embodiment of the earth leakage reactor shown according to the invention. i denotes the iron core and 2 the winding. The middle part: one leg consists of three iron packages 3 and four Air gaps. Between the undivided part of the iron core i and the adjacent ones Iron packets 3 and furthermore there is an air gap between each two iron packets.

Von den drei Eisenpaketen ist das obere nicht massiv, vielmehr ein Mantelkern. Auf dem Mittelschenkel dieses Eisenpaketes befindet s,icheineHilf swicklung, die an einer Gleichstromquelle angeschlossen ist. Fig. 2 zeigt .dasselbe Eisenpaket in vergrößertem Maßstab.Of the three iron packages, the upper one is not massive, rather one Sheath core. On the middle leg of this iron package there is an auxiliary winding, which is connected to a DC power source. Fig. 2 shows the same iron package on an enlarged scale.

Die Einstellung der Gleichstromvormagnetisierung kann von Hand oder selbsttätig erfolgen. Zur ,Speisung der Hilfswicklung wird zweckmäßigerweise gleichgerichteter Wechselstrom verwendet.The setting of the DC bias can be done manually or take place automatically. To feed the auxiliary winding is expediently more rectified AC used.

Um zu vermeiden, daß :der Wechselfluß in der Gleichstromwicklung eine Spannung -induziert; wird das Eisenpaket, wie aus Fig.3 hervorgeht, in Schichtrichtung unterteilt und die Gleichstromwicklung um die beiden durch die Unterteilung entstandenen mittleren Schenkel in Form einer Acht herumgelegt.To avoid that: the alternating flux in the direct current winding a Tension -induced; the iron package, as can be seen from Fig. 3, in the direction of the layers divided and the DC winding around the two created by the division middle leg in the shape of a figure eight.

Je nach dem Regelbereich können mehr oder weniger Eisenpakete in dieser Weise ausgeführt sein. Es empfiehlt sich dabei,.sämtlichelGleichstromwicklungen in Reihe zu schalten.Depending on the control range, there can be more or fewer iron packets in this Way to be executed. It is recommended to use all DC windings to be connected in series.
