  Wicklung für Hochspannungstransformatoren. 



   Bei Hochvolttransformatoren hat man bisher die Spulen durch einzelne Isolierteile gegeneinander abgestützt und Isolierzylinder lediglich verwendet zur elektrischen Isolierung der Hoch-und Niedervoltwicklung gegeneinander. Die Montage und Demontage dieser Wicklungen war unbequem. Der Aufbau des Transformators nach der Erfindung gestattet eine bequeme Montage und Demontage und gewährleistet trotz Verwendung nur weniger Einzelteile einen kräftigen und widerstandsfähigen Aufbau. 



   Gemäss der Erfindung werden die konzentrisch angeordneten Spulen von einem Isolationszylinder unter Verwendung von metallischen Tragringen und gitterartig gestellten Stäben aus Isolationsmaterial getragen. 



   Beispielsweise kann der Papierzylinder der Hochvoltwicklung ausschliesslich als Träger der Wicklung dienen. Er wird beiderseitig von der aus zwei parallel geschalteten Gruppen bestehenden Hoch-

  Die Wicklung schliesst beiderseits mit einem kräftigen Stahlgussdoppelring b und c ab, der mit Bolzen d zusammengehalten wird. Diese Ringe dienen als Träger der   Wicklungen/, , A, t   ; sie fangen axiale Schubkräfte ab und sind an dem Ende der Wicklung, das gegen Erde Hochspannung führt, abgerundet, so dass die Verteilung des elektrischen Feldes günstig beeinflusst wird. Sie sind mit einer der benachbarten Windungen elektrisch verbunden und, damit sie nicht als kurzgeschlossene Windung wirken, mindestens einmal radial geschlitzt. Um den Umlauf des Kühlmittels nicht zu stören, erhalten sie zahlreiche Kühlkanäle q. 



   Die eigentliche Wicklung ist in mehrere Spulen unterteilt. Die Kühlung erfolgt sowohl im Ölmantel wie auch in den Ölkanälen zwischen Wicklung und Tragzylinder.

   Die vollständig zusammengebaute Wicklung kann mit dem sie tragenden Papierzylinder zusammen montiert oder demontiert werden.

  Winding for high voltage transformers.



   In high-voltage transformers, the coils have hitherto been supported against one another by individual insulating parts, and insulating cylinders have only been used to electrically isolate the high-voltage and low-voltage windings from one another. The assembly and disassembly of these windings was inconvenient. The structure of the transformer according to the invention allows easy assembly and disassembly and ensures a strong and resistant structure despite the use of only a few individual parts.



   According to the invention, the concentrically arranged coils are supported by an insulation cylinder using metal support rings and bars made of insulation material in a grid-like manner.



   For example, the paper cylinder of the high-voltage winding can serve exclusively as a carrier for the winding. It is supported on both sides by the high-
 EMI1.1
 



   Figures 1 and 2 show an example of the arrangement. It denotes a the isolation cylinder.



  The winding ends on both sides with a strong cast steel double ring b and c, which is held together with bolts d. These rings serve as supports for the windings /,, A, t; they absorb axial shear forces and are rounded at the end of the winding that carries high voltage to earth, so that the distribution of the electric field is favorably influenced. They are electrically connected to one of the adjacent turns and, so that they do not act as a short-circuited turn, have a radial slot at least once. In order not to disturb the circulation of the coolant, they have numerous cooling channels q.



   The actual winding is divided into several coils. The cooling takes place both in the oil jacket and in the oil channels between the winding and the supporting cylinder.

 material is fixed. The rings and bars together form a network with rectangular mesh. The wrought iron rings are radially slotted for the same reason and in the same way as the cast steel rings.



   The fully assembled winding can be assembled or disassembled with the paper cylinder that supports it.
