Die einzelnen Papierschichten sind nun an den freien Enden nach innen umgelegt. Dabei legt sich der umgebogene Rand der dem Isolierrohr 8 unmittelbar benachbarten Papiersehieht 9 auf einen   VerseMussdeckel H   des   Isolierrohres 8   auf. Darauf liegt eine aus einzelnen Schichten gebildete Papierseheibe   M,   die einen   Metallbelag   enthält, der in der Zeichnung ebenfalls   gestriehelt   angedeutet ist. 



  Er ist leitend mit dem über der betreffenden zylindrischen Papierschicht 9 liegenden Metallbelag verbunden, der anderseits an das Ende der untersten Teilspule der   Hoehspannungswicklung angeschlossen   ist. Der Anfang dieser Spule steht über einen auf dem Isolierzylinder 8   angebrachten Metallbelag mit   dem geerdeten Eisenkern in Verbindung. Auf die unterste Papierscheibe 12 legt sich der umgebogene Rand der nächsten zylindrischen Papierschicht 9, darauf kommt wieder eine   Papierscheibe 12'usw.,   wobei   die Metallschiehten   in der in der Zeichnung angedeuteten Weise geschlossene leitende   Um-   hüllungen bilden. 



   Bei höheren Spannungen ist es zweckmässig, das Ganze in einem mit Öl gefüllten Gefäss anzuordnen. Um nun einen   Umlauf   des Öles zu ermöglichen,   können   in den Papierseheiben 1 ?, 12'Durchbrüehe vorgesehen sein, die vorzugsweise derart versetzt gegeneinander angeordnet sind, dass sie z. B. abwechselnd links   (12)   und rechts   (')   liegen. 



   Durch die beschriebene Bauart wird erreicht, dass die Gesamthöhe der Anordnung nicht viel grösser wird, als es durch die Höhe der Hochspannungswieklung bedingt ist. Im übrigen wirken die

   PATENT-ANSPRÜCHE :
1. Hochspannungswandler, insbesondere Messwandler, bei dem die auf einem offenen Eisenkern konzentrisch zueinander angeordnete Hochspannungs- und Niederspannungswicklung durch eine von Metalleinlagen durchsetzte und aus Papierschichten gewickelte Isolierhiille voneinander getrennt sind, dadurch gekennzeichnet, dass die Isolierhülle, deren   Papierschichten an   den freien Enden nach innen umgelegt und deren leitende Metalleinlagen durch besondere leitende Einlagen an der Stirnseite geschlossen sind, in Form einer Haube über das freie Ende des Eisenkerns gezogen ist.

The individual paper layers are now turned inwards at the free ends. In doing so, the bent edge of the paper sheet 9 immediately adjacent to the insulating tube 8 rests on a verse must cover H of the insulating tube 8. A paper disk M, formed from individual layers and containing a metal coating, which is also indicated in the drawing with stripes, lies thereon.



  It is conductively connected to the metal coating lying over the relevant cylindrical paper layer 9, which is connected on the other hand to the end of the lowermost coil section of the high voltage winding. The beginning of this coil is connected to the earthed iron core via a metal coating attached to the insulating cylinder 8. The bent edge of the next cylindrical paper layer 9 lies on the lowermost paper disk 12, and a paper disk 12 ′, etc., comes on top again, the metal layers forming closed conductive envelopes in the manner indicated in the drawing.



   At higher voltages it is advisable to place the whole thing in a container filled with oil. In order to enable the oil to circulate, breakthroughs can be provided in the paper disks 1?, 12 ', which are preferably offset from one another in such a way that they are e.g. B. are alternating left (12) and right (').



   The design described ensures that the overall height of the arrangement is not much greater than is caused by the level of the high voltage vibration. Otherwise they work

   PATENT CLAIMS:
1. High-voltage converter, in particular measuring converter, in which the high-voltage and low-voltage windings, which are arranged concentrically to one another on an open iron core, are separated from one another by an insulating sheath interspersed with metal inserts and wound from layers of paper, characterized in that the insulating sheath, whose paper layers at the free ends inward folded and whose conductive metal inserts are closed by special conductive inserts on the front side, is drawn in the form of a hood over the free end of the iron core.
