Description
Die Erfindung betrifft eine Ableitungsanordnung für Wechselstromschleifringe mit mehreren Bürsten.The invention relates to a derivation arrangement for alternating current slip rings with several To brush.
Es ist bekannt, daß bei Ableitung großer Wechselstromstärken von Schleifringen eine große Anzahl von Bürsten erforderlich ist. Da mit den gewöhnlichen Mitteln eine gleichmäßige Stromverteilung auf die einzelnen Bürsten nicht möglich ist, werden diese auch ίο ungleichmäßig beansprucht und abgenutzt.It is known that when deriving large alternating currents from slip rings a large number of brushes is required. Since with the usual means an even Power distribution to the individual brushes is not possible, these are also ίο unevenly stressed and worn.
Es ist bekannt, vor jede einzelne Bürste Drosselspulen mit unveränderlichem Luftspalt zu schalten, um eine stromregulierende Wirkung und damit eine gleichmäßige Beanspruchung der Bürsten zu bewirken.It is known to have reactors with a fixed air gap in front of each individual brush to switch in order to have a current-regulating effect and thus an even load effect of the brushes.
Die Erfindung erstrebt, eine beliebig einstellbare Stromverteilung auf die Bürsten dadurch zu erzielen, daß die Induktanz der Drosselspulen oder Drosselkerne durch einstellbare Luftspälte geändert werden kann; es ist dadurch möglich, die Stromverteilung beim Prüfen entsprechend den Erfordernissen einzustellen. So kann z. B. die Stromverteilung auf die einzelnen Bürsten oder Bürstengruppen gleiches mäßig oder auch verschieden hoch eingestellt werden, um gewissen, gut gekühlten Bürstengruppen einen höheren Strom aufzuzwingen. Die Einstellbarkeit des Luftspaltes der Drosselspulen hat noch den weiteren Vorteil, daß die geradlinige Charakteristik der Drosselspule auch bei Stromstößen praktisch erhalten bleibt, ebenso das Verhältnis der Stromverteilung auf die Bürsten bei Überlastungen.The invention seeks to achieve an arbitrarily adjustable current distribution to the brushes to achieve that the inductance of the choke coils or choke cores by adjustable Air gaps can be changed; it is through it possible to adjust the current distribution during testing according to the requirements. So can e.g. B. the power distribution to the individual brushes or brush groups the same can be set to a moderate or different level in order to achieve certain, well-cooled brush groups to impose a higher current. The adjustability of the air gap of the choke coils has the further advantage that the straight line characteristic of the choke coil is practically preserved even in the event of power surges, as well as the ratio of the power distribution the brushes in case of overload.
Ein weiterer Vorteil dieser Anordnung besteht darin, daß infolge der mit äußeren Mitteln erzwungenen gleichmäßigen Stromverteilung auf alle Bürsten die Stromdichte unter der Bürste höher als üblich gewählt werden kann, wodurch Bürsten gespart und damit kleinere Ringabmessungen möglich "werden.Another advantage of this arrangement is that as a result of the forced by external means Even current distribution to all brushes, the current density under the brush can be selected higher than usual, whereby Brushes are saved and thus smaller ring dimensions are possible ".
Ferner vermag man mit Bürsten sehr hoher Leitfähigkeit und geringster Übergangsspannung auszukommen, was wiederum einer Herabsetzung der Bürstenübergangsverluste bedeutet, wodurch abermals eine Verkleinerung des Ringdurchmesser ermöglicht wird. Hierdurch werden auch die Bürstenreibungsverluste geringer. In addition, brushes can be used to achieve very high conductivity and the lowest possible transition voltage get along, which in turn means a reduction in brush transfer losses, which again enables the ring diameter to be reduced. Through this the brush friction losses are also lower.
Auf der Zeichnung ist in Abb. 1 das Schema der erfindungsgemäßen Anordnung dargestellt.On the drawing, the scheme of the arrangement according to the invention is shown in Fig. 1.
Abb. 2 zeigt die Anordnung der in den Bürstenzuleitungen liegenden Drosseln.Fig. 2 shows the arrangement of the chokes located in the brush feed lines.
Von dem Schleifring α (Abb. 1) wird der Strom durch mehrere Bürsten b abgenommen. Die Widerstände c stellen die vorgeschalteten Widerstände in Form der Leitungen und der Bürstenübergangsspannung dar, während die Widerstände d die erfindungsgemäß vorgeschalteten Induktivitäten andeuten.The current is taken from the slip ring α (Fig. 1) by several brushes b. The resistors c represent the upstream resistances in the form of the lines and the brush junction voltage, while the resistors d indicate the upstream inductances according to the invention.
In Abb. 2 sind die über den Stromzuleitungen u,v,w angeordneten Drosselkerne k dargestellt, welche mit einstellbaren Luftspalten O1, ö2 und O3 versehen sind. Die Verschiedenheit in der Luftspaltgröße ist dabei absichtlich unmaßstäblich angegeben, um das Prinzip der erfindungsgemäßen Anordnung besser zur Veranschaulichung zu bringen. Die Festlagerung der Luftspalte geschieht hierbei zweckmäßig durch Distanzbleche aus unmagnetischem Material. FIG. 2 shows the inductor cores k arranged over the power supply lines u, v, w , which are provided with adjustable air gaps O 1 , O 2 and O 3 . The difference in the size of the air gap is intentionally not shown to scale in order to better illustrate the principle of the arrangement according to the invention. The air gaps are fixed in place by means of spacer plates made of non-magnetic material.
