Description

Hochspannungstrockentransformator der Kerntype mit Zylinderwjcklung, dessen Oberspannungswicklung unter Verwendung zweier bewickelter Schenkel auf mehrere konzentrische, in Reihe geschaltete Tragzylinder aus Isolierstoff verteilt ist. Hochspannungstransformatoren mit Luftisolation bieten namentlich für Prüfzwecke mancherlei Vorteile gegenüber solchen mit Ölisolation. Die für Öltransformatoren bisher gefundenen Lösungen für die Anordnung der Wicklungen sind aber nicht ohne weiteres für Transformatoren mit Luftisolation zu verwenden. Von wesentlicher Bedeutung ist z. B. die Notwendigkeit der stetigen Erneuerung der Luft an allen Stellen, damit sie ihren Aufgaben zur Kühlung und Isolierung gerecht werden kann. Hochspannungstransformatoren mit Luftisolation müssen ferner so gebaut sein, daß ein Überschlag nicht das Isoliermaterial beschädigen kann; es müssen daher dem Lichtbogen eigene Wege gewiesen werden, und die Fußpunkte der Lichtbögen werden im allgemeinen auf Metall liegen müssen.Core type high voltage dry transformer with cylindrical winding, its high-voltage winding using two wound legs on several concentric, series-connected support cylinder made of insulating material is distributed. High-voltage transformers with air insulation are used specifically for testing purposes various advantages over those with oil insulation. The ones for oil transformers Solutions found so far for the arrangement of the windings are not without can also be used for transformers with air insulation. Essential is z. B. the need for constant renewal of the air in all places, so it can meet its cooling and insulation tasks. High voltage transformers with air insulation must also be built in such a way that a flashover does not damage the insulating material can damage; it must therefore be shown the arc of its own way, and the base points of the arcs will generally have to be on metal.

Aus diesen Gründen ist z. B. eine Wicklungsanordnung nach der amerikanischen Patentschrift r 129472, bei welcher vier Kerne eines Eisenkörpers so bewickelt sind, daß sich der Anfang der Wicklung des einen Kernes an das Ende der Wicklung des vorhergehenden anschließt, für Lufttransformatoren unbrauchbar. In den wagerecht angeordneten Wicklungszylindern wird sich nämlich die Luft nicht ohne weiteres laufend erneuern.For these reasons, z. B. a winding arrangement according to the American Patent specification r 129472, in which four cores of an iron body are wound in this way that the beginning of the winding of one core is connected to the end of the winding of the previous one connected, useless for air transformers. In the horizontally arranged winding cylinders the air will not be constantly renewed without further ado.

Bei Transformatoren gemäß der Erfindung werden auf zwei Kernen mehrere Trag -zylinder a,, a_, ausw. (Abb. z) angeordnet, die entweder in Lagen oder in Form von hintereinandergeschalteten Spulen in üblicher Weise bewickelt sind. Der innerste Wicklungszylinder a1 erzeugt die erste Spannungsstufe. Während der Wicklungsänfang bis dicht an das Joch reicht und mit diesem elektrisch verbunden sein kann, muß das Wicklungsende bereits einen größeren Abstand vom Joch haben. Dieses Wicklungsende wird mit dem Wicklungszylinder a" auf dem anderen Schenkel verbunden, dessen Anfang vom Joch ebensoweit absteht wie das Wicklungsende auf dem Zylinder a1. Das Ende von a., hat wieder ein höheres Potential und muß daher noch «-eiter vom Joch entfernt bleiben. Dieses Ende wird mit der Wicklung auf Zylinder a3 des ersten Schenkels verbunden. Das Ende dieser Wicklung bleibt wiederum etwas mehr vom Joch entfernt usw.In transformers according to the invention, two cores are more than one Support cylinder a ,, a_, select. (Fig.z) arranged either in layers or in Form of series-connected coils are wound in the usual way. Of the innermost winding cylinder a1 generates the first voltage level. During the winding start until it reaches close to the yoke and can be electrically connected to it, must the end of the winding already have a greater distance from the yoke. This winding end is connected to the winding cylinder a "on the other leg, its beginning protrudes from the yoke just as much as the end of the winding on the cylinder a1. The end from a., has a higher potential again and therefore has to be removed from the yoke stay. This end becomes the winding on cylinder a3 of the first leg tied together. The end of this winding remains a little further away from the yoke etc.

Es kann eine ganze Anzahl von Wicklungsträgern angeordnet sein, deren Wicklungen ein immer höheres Potential annehmen, und die sich dabei immer mehr vom Kern und vom Joch entfernen. Der Durchmesser der Zylinder- kann so .ge-,vählt werden, daß die Beanspruchung der Luft an den jeweiligen äußeren Oberflächen . der Zylinder nirgends den zulässigen Wert überschreitet. Da durch die Verbindungsleitungen dem Raum nach den Jochen zu Zwangspotentiale erteilt werden, so ist das ganze Fenster des Transformators in der günstigsten Weise zur Überwindung der Spannung ausgenutzt. Das Potential steigt also von o aus bis zu seinem Höchstwerte in regelmäßigen Stufen an.It can be arranged a number of winding supports, their Windings assume a higher and higher potential, and which are more and more from the Remove core and yoke. The diameter of the cylinder can be chosen so. that the strain on the air on the respective outer surfaces. the cylinder does not exceed the permissible value anywhere. Since the connecting lines to the Space after the yokes to be granted coercive potentials, so is the whole window of the transformer is used in the most favorable way to overcome the voltage. The potential thus rises from 0 to its maximum value in regular steps at.

Soll die Mitte der Wicklung geerdet sein, so werden die Wicklungen der einzelnen Zylinder zu je zwei Hälften unterteilt und die in der gleichen Höhe liegenden Wicklungsabteilungen des rechten und linken Schenkels in der beschriebenen Weise hintereinandergeschaltet. Die Gesamtspannung beträgt dann 2 Tl, wenn jede Abteilung die Spannung V gegen Eisen hat (Abb. 2) .If the center of the winding is to be earthed, the windings will be of the individual cylinders divided into two halves and those in the same height lying winding departments of the right and left leg in the described Way connected in series. The total tension is then 2 Tl if each Division has the voltage V against iron (Fig. 2).
