Description

Hochspannungslufttransformator mit konzentrischer Wicklung, bei dem die außen angeordnete Hochspannungswicklung von der Niederspannungswicklung durch einen breiten Luftmantel getrennt ist. Die Erfindung bezweckt, einem Hochspannungslufttransformator mit konzentrischer Wicklung und breitem Luftmantel zwiischen der außenliegenden Hochspannungswicklung und der innenliegenden Niederspannungswicklung einen sicheren Schutz gegen Randentladungen zwischen den beiden Wicklungen einerseits und zwischen der Wicklungsstirn der Hochspannungswicklung und Joch andererseits zu verleihen und so unter sonst gleichen Größenverhältnissen eine höhere Spannung zu ermöglichen. In an sich bekannter Weise ist das die Höchstspannung führende Ende der Hochspannungswicklung mit einem rundlichen Schirmwulst versehen und sind (wenigstens der Regel nach) .zwischen den beiden Wicklungen zwei durch einen Luftraum. getrennte Isolierzylinder angeordnet, von denen der äußere reit dem Ende der Hochspannungswicklung abschneidet. Erfindungsgemäß .ist nun im Längenbereich des Höchstspannungsendes der Hochspannungswicklung ein von der innenliegenden Niederspannungspule in kelchähnlicher Krümmung achsial und zugleich nach außen entwickelter Schirmkörper angeordnet und der Schirmwulst der Hochspannungswicklung derart kelchähnlich nach außen ausgebogen, daß zwischen den beiden Schirmkörpern ein nach außen sich stetig erweiternder Ringspalt entsteht. Indem der Ringwulst der Hochspannungswicklung schließlich wieder gegen die Außenfläche der Endspulen zurückgebogen ist, wird außer der Schirmwirkung gegenüber der Innenspule und dem Joch auch eine zweckmäßige Ab- schirmung gegenüber der benachbarten Spule oder sonstigen in der Nähe befindlichen Körpern anderen Potentialis erzielt.High-voltage air transformer with concentric winding, in which the externally arranged high-voltage winding is separated from the low-voltage winding by a wide air jacket. The aim of the invention is to give a high-voltage air transformer with concentric winding and a wide air jacket between the external high-voltage winding and the internal low-voltage winding reliable protection against edge discharges between the two windings on the one hand and between the winding face of the high-voltage winding and yoke on the other, and thus a higher voltage under otherwise identical proportions to enable. In a manner known per se, the end of the high-voltage winding carrying the maximum voltage is provided with a rounded shield bead and (at least as a rule) there are two through an air space between the two windings. Separate insulating cylinders are arranged, of which the outer one cuts off the end of the high-voltage winding. According to the invention, in the length range of the extra-high voltage end of the high-voltage winding, a shield body is arranged axially and at the same time outwardly from the inner low-voltage coil in a cup-like curvature, and the shielding bead of the high-voltage winding is bent outwards in such a cup-like manner that an annular gap is created between the two shield bodies that constantly widens outwards . By the annular ring of the high-voltage winding is ultimately bent back against the outer surface of the end coils is in addition to the shielding effect against the inner coil and the yoke also a convenient waste shielding respect to the adjacent coil or other to nearby bodies other potentialis achieved.

Die Abbildung zeigt eine Ausführungsform der Erfindung. a ist das Joch, b der Kern des Transformators. Auf dem- Kern b ist die Niedervoltwicklung c angeordnet, über welche ; der von Joch zu Joch reichende. ; Iunen- zylinder d geschoben ist. Dieser triert durch Eindrehungen in derf.@dscgi ben e und f. Der kürzere äußer2Isü@i: zylinder g ist am Ende mit einem ver"tteri Ring h versehen und ebenfalls zentrieatlf' die Platte e aufgesetzt und beispielsweise durch Schrauben damit verbunden. i @5ezeIch- net die verstärkten Eingangspulen und k die Hauptspulen der Hochspannungswicklung. Zum Schutz der erstgenannten isf aüßen ein kurzer Isolierzylinder l übergeschoben. Die oberen Enden der Zylinder g und l sind .von dem metallischen Ringwulst m umschlossen, der mit der letzten Spule von i leitend verbunden ist, also unter der höchsten Spannung steht.The figure shows an embodiment of the invention. a is the yoke, b the core of the transformer. The low-voltage winding c is arranged on the core b, via which ; the one reaching from yoke to yoke. ; Iunen- cylinder d is pushed. This traversed by indentations in derf. @ dscgi ben e and f. The shorter outer2Isü @ i: cylinder g has a ver "tteri at the end Ring h and also centrieatlf ' the plate e placed and for example connected to it by screws. i @ 5ezeIch- net the amplified input coils and k the main coils of the high voltage winding. To protect the first-named feet, a short insulating cylinder l is pushed over. The upper ends of the cylinders g and l are enclosed by the metallic ring bead m, which is conductively connected to the last coil of i, i.e. is under the highest voltage.

Die äußere Oberfläche deis Innenzylinders d wird durch den kelchförmigen Metallkörper n ebenfalls in einen Ringwulst übergeführt, welcher mit dem Jocheisen verbunden ist. Der Wulst m und der Körper n sind als konzentrische Kugelflächen aufzufassen, während die Wülste m der beiden Schenkel sich gegeneinander wie zwei Kugeln mit großem Radius verhalten.The outer surface of the inner cylinder d is also converted into an annular bead by the cup-shaped metal body n, which is connected to the yoke iron. The bulge m and the body n are to be understood as concentric spherical surfaces, while the bulges m of the two legs behave towards each other like two balls with a large radius.
