Description
Gegenstand des Patents 947 917 ist eine Anordnung zurr praktisch stufenlosen Spannungsregelung von Transformatoren, bei denen die; Überschaltung von; einer Grobstufe auf die nächste Grobstufe durch zwei Schalttransformatoren vorgenommen wird, die sekundärseitig gemeinsam mit einer durch einen Kollektor feinstufig regelbaren Drossel belastet sind., derart, d.aß sich, die Belastung der beiden Schalttrans.formatoren in. umgekehrter Folge in Abhängigkeit von der Bürstenstellung zwischen Kurzschluß und, Leerlauf kontinuierlich ändert.The subject of patent 947 917 is an arrangement for practically stepless movement Voltage regulation of transformers in which the; Override of; a coarse level to the next coarse level is made by two switching transformers, the on the secondary side together with a throttle that can be finely regulated by a collector are loaded., that is, the load on the two switching transformers in reverse order depending on the brush position between short circuit and, idle changes continuously.
Bei diesen. Anordnungen, zur Spannungsregelung sind die Drossel und der Kollektor getrennt voneinander ausgebildet, so. daß jeder Anzapfpunkt der Drossel durch eine Leitung mit der entsprechenden Lamelle; des Kollektors verbunden werden muß. Infolgedessen ist eine Vielzahl von Leitungen und ein entsprechender Raumbedarf erforderlich.With these. Arrangements for voltage regulation are the choke and the collector formed separately from each other, so. that each tapping point of the throttle through a line with the corresponding lamella; of the collector got to. As a result, a large number of lines and a corresponding space requirement necessary.
Nach der Erfindung wird demgegenüber eine wesentliche Verringerung des Raumbedarfs und eine wesentliche Vereinfachung dadurch erzielt, daß die Drossel mit den Kollektor baulich so vereinigt ist, daß die Kollekto;rlamellen Teile der Wicklung der Drossel darstellen. Das heißt, die Wicklung der zweckmäßig mit einem Ringkern ausgeführten: Drossel ist selbst als Kollektor ausgebildet, auf dem diel Bürsten unmittelbar schleifen. Die Bürsten können dabei sowohl auf den Mantelflächen als auch an den Stirnflächen der Drosselwicklung aufliegen.According to the invention, on the other hand, there is a substantial reduction the space requirement and a substantial simplification achieved in that the throttle is structurally united with the collector in such a way that the collector lamellae parts of the Represent the winding of the choke. That is, the winding of the expedient with one Executed toroidal core: the choke itself is designed as a collector on which the dielectric Grind brushes immediately. The brushes can be used both on the lateral surfaces as well as on the end faces of the inductor winding.
Die Erfindung wird nachstehend an. Hand der Zeichnung an einem Ausführungsbeispiel noch näher beschrieben.The invention is hereinafter referred to. Hand drawing on an exemplary embodiment described in more detail.
Fig. I zeigt zunächst die grundsätzliche Schaltung der als solche bereits vorgeschlagenen Anordnung zur Spannungsregelung von Transformatoren. Dabei bezeichnet 1 die Wicklung des Stufentransformators mit zwei benachbarten Stuf enschalterkontakten 2 und 3. An diesen sind die beiden Schadttransformataren 4 und 5 ange schlossen, die mit ihren anderen Enden miteinander und der Ableitung 6 verbunden; sind. In dem Stromkreis der Sekundärwicklungen der beiden Schalttransformatoren. liegt die feinstufig angezapfte Drossel 7, an deren Anzap,fpunkte die Lamellen des Kollektors 8 angeschlossen sind. Von den Bürsten des Koilektoirs führt eine! Leitung zu den anderen, miteinander verbundenen; Enden der Sekundärwicklungen der Schalttransformatoren.FIG. I first shows the basic circuit of the arrangement already proposed as such for regulating the voltage of transformers. 1 denotes the winding of the step transformer with two adjacent step enschalterkontakten 2 and 3. The two Schadttransformataren 4 and 5 are connected to these, which are connected at their other ends to each other and the derivative 6; are. In the circuit of the secondary windings of the two switching transformers. is the finely tapped throttle 7, to whose tap, f points the lamellae of the collector 8 are connected. One of the brushes in the Koilektoir leads! Line to the other, interconnected; Ends of the secondary windings of the switching transformers.
Die erfindungsgemäße bauliche Zusammenfassung von Drossel und. Kollektor zeigt Fig. 2.The inventive structural combination of throttle and. collector Fig. 2 shows.
Die den ringförmigen; lamellierten. Eisenkern 12 umschlingende Wicklung g besteht dabei aus den Lamellen 1o und den leitenden Bügeln; 11, die erstere fortschreitend miteinander verbinden.The the ring-shaped; laminated. Iron core 12 looped winding g consists of the lamellae 1o and the conductive brackets; 11, the former progressive connect with each other.
Die auf den Lamellen 1o liegenden Bürsten sind nicht eingezeichnet. Die Windungsspannung je Stufe ist dabei gleich der Lamellenspannung, so daß sich konstruktiv eine besonders einfache Farm ergibt.The brushes lying on the slats 1o are not shown. The winding voltage per step is equal to the lamella voltage, so that constructively results in a particularly simple farm.
