Description
Transformator für sehr hohe Ströme mit mehreren betriebsmäßig parallel und in Serie schaltbaren Starkstromspulen, bei dem die in einer Flucht angeordneten Anschlußleiter abwechselnd zur Hin- und Rückleitung verwendet werden Bei Transformatoren für sehr hohe Stromstärken mit zwei oder mehr getrennten Sekundärstromkreisen, die mittels einer außerhalb des Behälters angebrachten Schalteinrichtung je nach Bedarf betriebsmäßig par. alle' oder in Reihe geschaltet werden sollen, macht die Unterbringung der Verbindungsleitungen zwischen den Spulenenden und den Deckelklemmen große Schwierigkeiten. Besonders unangenehm ist dabei, daß der in dem einen Verbindungsleiter fließende Strom Streufelder hervorruft, die den Strömen in den benachbarten Leitern nach den bekannten .Gesetzen der Stromverdrängung entgegenwirken. Diese Wirkung tritt besonders dann stark hervor, wenn mehrere in der gleichen 'Richtung vom Strom durchflossene Leiter zueinander parallel liegen und nur geringen Abstand voneinander haben.Transformer for very high currents with several operating in parallel and high-voltage coils that can be switched in series, in which the Connecting conductors can be used alternately for the outgoing and return lines. For transformers for very high currents with two or more separate secondary circuits that by means of a switching device attached outside the container as required operational par. all 'or to be connected in series makes the accommodation the connecting lines between the coil ends and the cover terminals great difficulties. It is particularly uncomfortable that the one flowing in the one connecting conductor Current causes stray fields, which the currents in the neighboring conductors according to the counteract the well-known laws of current displacement. This effect occurs especially then strong when several in the same direction were flowed through by the current Conductors are parallel to each other and have only a small distance from each other.
Die Abb. i der Zeichnung stellt einen solchen Transformator dar.Fig. I of the drawing shows such a transformer.
Auf dem Kern i sitzen die Sekundärwicklungen a, 3, q. mit den Wicklungsenden a bis f, die an die Klemmen A bis F angeschlossen sind. Die Primärwicklung ist der Einfachheit halber weggelassen. Die Verbindungsleiter 5 liegen in einer Ebene, derart, daß die an die gleichpoligen Wicklungsenden a, c, e und/bzw. b,; d, f angeschlossenen Leiter parallel nebeneinander herlaufen. Diese Schaltungsweise ermöglicht zwar eine bequeme Verbindung zwischen Wicklungsenden und Klemmen und kann mit einfachen, nur an einer Stelle abgebogenen Leitern ausgeführt werden, ist aber infolge des Auftretens einer starken Stromverdrängung für Transformatoren mit sehr hohen Strömen nicht geeignet. The secondary windings a, 3, q sit on the core i. with the winding ends a to f, which are connected to the terminals A to F. The primary winding is omitted for the sake of simplicity. The connecting conductors 5 lie in one plane in such a way that the ends a, c, e and / or at the homopolar winding ends. b ,; d, f connected conductors run parallel to each other. Although this type of circuit allows a convenient connection between winding ends and terminals and can be carried out with simple conductors bent at only one point, it is not suitable for transformers with very high currents due to the occurrence of strong current displacement.
Die Wirkung der Stromverdrängung kann abgeschwächt werden, wenn man den Transformator nach Abb. z schaltet. Hier liegen die Verbindungsleiter in zwei getrennten Ebenen. In verschiedener Richtung vom Strom durchflossene Leiter liegen paarweise beisammen. Diese Ausführung hat jedoch den Nachteil, daß sie viel Platz beansprucht und eine Vergrößerung des Transformatorbehälters verlangt, weil die Wicklungsenden a bis f nach unten zu treppenartig vorgebaut werden müssen; wie die Abb. z zeigt.The effect of the current displacement can be weakened if one switches the transformer according to Fig. z. Here the connecting conductors are in two separate levels. Conductors through which the current flows in different directions together in pairs. However, this version has the disadvantage that it takes up a lot of space claimed and an enlargement of the transformer tank required because the Winding ends a to f must be built in front of the bottom like a staircase; as the Fig.z shows.
Durch die Erfindung werden diese Schwierigkeiten beseitigt. Erfindungsgemäß wechseln bei der übereinanderschichtung der einzelnen Starkstromspulen längs des Eisenkerns Spulen mit gekreuzten Wicklungsenden und solche ohne gekreuzte Wicklungsenden ab. Die Anschlußleiter, die in einer Flucht angeordnet sind, werden abwechselnd zur Hin- und Rückleitung verwendet. Dieser Aufbau des Wicklungsschenkels ermöglicht eine Ausführung der Verbindungsleitungen, die die Vorteile der Ausführungen nach den Abb. i und 2 vereinigt, von deren Nachteilen jedoch frei ist.The invention overcomes these difficulties. According to the invention change when the individual high-voltage coils are stacked along the Iron core coils with crossed winding ends and those without crossed winding ends away. The connecting conductors, which are arranged in an alignment, are alternated used for outward and return lines. This structure of the winding leg enables an execution of the connecting lines, which the advantages of the executions according to fig. i and 2 are combined, but are free from their disadvantages.
In Abb. 3 ist im Schema eine Ausführung der Erfindung beispielsweise dargestellt. Der Wicklungsschenkel des Transformatorkerns i setzt sich aus zwei verschiedenen Spulenarten zusammen; die eine Art, z. B. Spule 2, hat nichtgekreuzte, die andere, beispielsweise Spule 3, hat gekreuzte Wicklungsenden. Die Verbindungsleiter 5 haben dieselbe einfache Form wie in Abb. i; benachbarte Leiter werden aber nicht wie dort von gleichgerichteten, sondern von entgegengesetzt gerichteten Strömen durchflossen wie in Abb. 2. Dadurch wird die Wirkung der Stromverdrängung fast vollständig beseitigt, besonders dann, wenn alle Spulen gleichmäßig belastet sind. Dies bietet den Vorteil, daß die Leiter ziemlich nahe nebeneinander angeordnet werden können.In Fig. 3, an embodiment of the invention is for example in the scheme shown. The winding leg of the transformer core i consists of two different types of coils together; one kind, e.g. B. Spool 2, has non-crossed, the other, for example coil 3, has crossed winding ends. The connecting ladder 5 have the same simple shape as in Fig. I; however, neighboring conductors will not as there from currents directed in the same direction, but from currents directed in opposite directions flowed through as in Fig. 2. As a result, the effect of the current displacement is almost complete eliminated, especially when all coils are equally loaded. This offers the advantage that the conductors can be arranged quite close to one another.
Ein weiterer Vorteil dieser Ausführung besteht darin, daß die Schaltvorrichtung, durch die je nach Bedarf die einzelnen Spulen parallel oder in Reihe geschaltet werden sollen, sehr einfach ausfällt; sie ist in Abb. 4. und 5 beispielsweise dargestellt. A bis H sind die nach Abb. 3 mit den Wicklungsenden verbundenen Klemmen; sie sind in einer Reihe angeordnet. Parallel dazu sind zwei Reihen von Schaltmessern 6 bis 13 und 14 bis 18 angebracht, die je mittels einer Achse 19 und mittels Böcken 2o schwingbar an dem Behälterdeckel 21 (Abb.5) gelagert sind. An jedes Schaltmesser der Reihe 6 bis 13 sind Kabel 2-- angeschlossen, die zur Verbrauchsstelle führen. Jedes Messer der Reihe 6 bis 13 ist, wie durch Schraffur angedeutet, auf einer Seite isoliert; in der Reihe i¢ bis 18 wechseln ;netallische Messer 14, 16, 18 mit Messern aus Isoliermaterial 15, 17 ab.Another advantage of this design is that the switching device, through which the individual coils are to be connected in parallel or in series as required, turns out to be very simple; it is shown in Figs. 4 and 5, for example. A to H are the terminals connected to the winding ends as shown in Fig. 3; they are arranged in a row. In parallel, two rows of switch blades 6 to 13 and 14 to 18 are attached, each of which is mounted on the container lid 21 (FIG. 5) so that it can swing by means of an axis 19 and by means of brackets 2o. Cables 2-- are connected to each switch blade in rows 6 to 13, which lead to the point of consumption. Each knife of the row 6 to 13 is, as indicated by hatching, insulated on one side; Change in row i ¢ to 18; metallic knives 14, 16, 18 with knives made of insulating material 1 5, 17 alternate.
Auch die Bedienung der Schalteinrichtung ist sehr einfach. Sollen beispielsweise alle Wicklungen parallel geschaltet werden, so werden die Messer der Reihe 6 bis 13 zwischen die Kontakte A bis 0 eingelegt. Sollen sie in Reihe geschaltet werden, so werden die Messer der Reihe i q. bis 18 eingelegt und außerdem die Messer 6 und 9 der anderen Reihe. In entsprechender Weise können gemischte Schaltungen ausgeführt werden.The switching device is also very easy to operate. For example, if all windings are to be connected in parallel, the blades in rows 6 to 13 are inserted between contacts A to 0. If they are to be connected in series, the knives in series i q. to 18 and also knives 6 and 9 of the other row. Mixed circuits can be implemented in a corresponding manner.
