Description

Hochspannungstransformator, gebildet aus mehreren in Reihe geschalteten Einzeltransformatoren, die aus je einem Haupt- und einem Zwischentransformator bestehen, deren Wicklungen auf mehrere Schenkel desselben magnetischen Kreises verteilt sind Gegenstand der Erfindung ist ein Hochspannungstransformator, dessen Wicklungen so angeordnet sind, daß die durch Reaktanz auftretenden Verluste, die bei in Reihe geschalteten Transformatoren, die zusammen einen Hochspannungstransformator bilden, recht erheblich sind, auf ein Mindestmaß beschränkt werden.High-voltage transformer made up of several series-connected Individual transformers, each consisting of a main and an intermediate transformer, whose windings are distributed over several legs of the same magnetic circuit The invention relates to a high-voltage transformer whose windings are so are arranged that the losses caused by reactance that occur in series switched transformers, which together form a high-voltage transformer, are quite substantial, should be kept to a minimum.

Es ist zwar bekannt, Hochspannungstransformatoren aus mehreren in Reihe geschalteten, aus je einem Haupt- und einem Zwischentransformator bestehenden Einzeltransformatoren zu bilden, deren Wicklungen auf mehrere Schenkel desselben magnetischen Kreises verteilt sind. Der den Gegenstand der Erfindung bildende Transformator unterscheidet sich von den bekannten aber dadurch, daß die sekundäre Wicklung jedes Haupttransformators und die , sekundäre Wicklung jedes Zwischentransformators mit je einer Erregerwicklung zusammen auf verschiedenen Schenkeln desselben magnetischen Kreises untergebracht und beide Erregerwicklungen jedes Transformatorelementes parallel geschaltet sind.Although it is known to use high-voltage transformers from several in Series connected, each consisting of a main and an intermediate transformer Form single transformers, the windings of which on several legs of the same magnetic circuit are distributed. The transformer forming the subject of the invention differs from the known but in that the secondary winding of each Main transformer and the secondary winding of each intermediate transformer one excitation winding each together on different legs of the same magnetic Circle housed and both excitation windings of each transformer element in parallel are switched.

Auf der Zeichnung ist eine besondere Ausführungsform der Erfindung als Öltransformator dargestellt. Abb. r zeigt einen senkrechten Schnitt durch ein Transformatorelement, auf dessen beiden Schenkeln die Wicklungen. wie vorbeschrieben, angeordnet sind. Abb. a zeigt schematisch die Schaltung einer Gruppe von zwei in Reihe geschalteten Elementen.The drawing shows a particular embodiment of the invention shown as an oil transformer. Fig.r shows a vertical section through a Transformer element, on the two legs of which the windings. as described above, are arranged. Fig. A shows schematically the circuit of a group of two in Series of switched elements.

Der magnetische Kern trägt auf dem einen Schenkel 2 (Abb. z ) die Prrirnärwicklung 3 des Haupttransformators sowie seine Sekundärwicklung .I. Der andere Schenkel trägt die Primärwicklung 5 des Zwischentransformators sowie seine Sel:undänvicklung 6. Die isolierenden Zylinder 7 und g trennen die Primärwicklungen von den Sekundärwicklungen eines jeden Transformators. Das Ganze ist in einem Ölbehälter 9 eingetaucht.The magnetic core carries on one leg 2 (Fig. Z) the Primary winding 3 of the main transformer and its secondary winding .I. Of the other leg carries the primary winding 5 of the intermediate transformer as well as his Sel: undänvicklung 6. The insulating cylinders 7 and g separate the primary windings from the secondary windings of each transformer. The whole thing is in an oil container 9 immersed.

Bei dein in Abb. 2 dargestellten Schema der Schaltung ist die Stromquelle finit to bezeichnet. Die Primärwindungen sind bei r z durch die Wandung der Ölbehälter hindurchgeführt. Die Anfänge der Sekundärwicklungen a. sind bei 12 mit dem zugehörigen Behälter verbunden. 13 sind die Durchführungen des anderen Endes dieser Wicklungen; die eine genügende Isolation bieten müssen, um die von dem Transformatorelement erzeugte Gesamtspannung gegen Erde auszuhalten. 14 sind die Durchführungen für die Enden der Sekundärwicklung der Zwischentransformatoren. Diese Klemmen müssen dieselbe Isolation bieten wie die Klemmen 13. Die Klemmen 13 und 14 jedes Elementes können zu einer einzigen Klemme vereinigt werden, wie weiter unten ausgeführt. Das erste Element wird durch seine Klemmen i i mit der Stromquelle verbunden, und der Punkt i2 wird an Erde gelegt sein. Das zweite Element wird von der Erde mit der Spannung des Punktes 13 des ersten Elementes isoliert sein. Dieser Punkt wird bei 12 mit dem zweiten Element verbunden sein. Die Enden der Wicklung 6 des ersten Elementes werden mit den Klemmen i i des zweiten Elementes verbunden sein.In the circuit diagram shown in Fig. 2, the current source is denoted finit to. At rz, the primary windings are passed through the wall of the oil container. The beginnings of the secondary windings a. are connected at 12 to the associated container. 13 are the bushings at the other end of these windings; which must provide sufficient insulation to withstand the total voltage generated by the transformer element against earth. 14 are the bushings for the ends of the secondary winding of the intermediate transformers. These terminals must provide the same insulation as the terminals 13. The terminals 13 and 14 of each element can be combined into a single terminal, as explained below. The first element will be connected to the power source by its terminals ii, and point i2 will be connected to earth. The second element will be isolated from the earth with the voltage of point 13 of the first element. This point will be connected to the second element at 12. The ends of the winding 6 of the first element will be connected to the terminals ii of the second element.

Um die Bauart zu vereinfachen und für jedes Element nur eine einzige Klemme von hoher Spannung zu haben, kann ein beliebiger Punkt des Elementes 6 mit der Klemme 13 verbunden und damit für die Abführungsleitungen eine einzige Klemme benutzt werden.In order to simplify the construction and to have only a single high-voltage terminal for each element, any point of the element 6 can be connected to the terminal 13 and a single terminal can thus be used for the discharge lines.

Diese Bauart hat den Vorteil, daß für einen und den anderen der beiden Transformatoren die Gesamtlänge des Schenkels verfügbar bleibt. Sie vermeidet außerdem das übereinanderlagern der Wicklungen des Haupt-und Zwischentransformators, wodurch das Auseinandernehmen der Wicklungen bei Beschädigungen wesentlich erleichtert wird.This design has the advantage that for one and the other of the two Transformers the total length of the leg remains available. She also avoids the superimposing of the windings of the main and intermediate transformer, whereby the dismantling of the windings in the event of damage is made much easier.
