Description
<Desc/Clms Page number 1>
Transformator, insbesondere für Kleinröntwenapparate.
EMI1.1
<Desc/Clms Page number 2>
Der aus Kern und Wicklungen gebildete walzenförmige Körper wird in dem zylindrischen
Gehäuse 10 angeordnet, das ilm so eng umschliesst, dass nur noch das notwendige Isoliermittel (Öl) darin
Platz findet, aber praktisch kein unausgenutzter Raum übrigbleibt. Die Stirnflächen des Gehäuses können-nach Art einer Anäroidbarometerdose-elastisch ausgebildet sein, so dass sie die Wärme- ausdehnnng des Öles auszugleichen vermögen. Ausserdem sind die Stirnflächen des Gehäuses leicht nach aussen gewölbt. Die Form des Gehäuses wird dadurch dem walzenförmigen Körper, zu dessen Aufnahme es bestimmt ist, angepasst.
Um an Gewicht zu sparen, kann man bei dem Transformatorgehäuse die üblichen, verhältnismässig schweren, öldiehten Verschraubungen der einzelnen Teile dadurch vermeiden, dass man es aus zwei oder mehreren Teilen herstellt, die durch Löten oder Falzen öldicht zusammengefügt sind.
In an sich bekannter Weise kann das Transformatorgehäuse so ausgebildet sein, dass es auch noch zur'Aufnahme einer Röntgenröhre geeignet ist.
PATENT-ANSPRÜCHE :
1. Hochspannungstransformator, insbesondere für tragbare Kleinröntgenapparate, mit ringförmig angeordneten Kupferwicklungen, deren Ringöffnung von einem aus Eisenblechen bestehenden l1ittelkern ausgefüllt ist, der die Gestalt eines Zylinders mit ebenen, senkrecht zur Achse des Zylinders liegenden Grund- und Deckflächen aufweist und der gegebenenfalls die Primärwicklung trägt, dadurch gekennzeichnet, dass der magnetische Schluss des Eisenweges durch U-förmige Eisenbleche gebildet ist, die derart verdrillt sind, dass sie mit ihren Enden dicht nebeneinander radial auf den die Wicklungen
EMI2.1
dachziegelartig übereinanderliegen und diese mit Ausnahme der Stellen,
an denen die Enden der Hoch- spannnngswieklung nach aussen geführt sind, bedecken.

Transformer, especially for small X-ray apparatus.
EMI1.1
<Desc / Clms Page number 2>
The roller-shaped body formed from the core and windings is in the cylindrical
Housing 10 is arranged, which surrounds it so tightly that only the necessary insulating medium (oil) is left in it
Find space, but practically no unused space is left. The end faces of the housing can - in the manner of an anaeroid barometer box - be designed to be elastic, so that they are able to compensate for the thermal expansion of the oil. In addition, the end faces of the housing are slightly curved outwards. The shape of the housing is thereby adapted to the cylindrical body which it is intended to receive.
In order to save weight, you can avoid the usual, relatively heavy, oil-tightened screw connections of the individual parts of the transformer housing by making it from two or more parts which are joined together oil-tight by soldering or folding.
In a manner known per se, the transformer housing can be designed in such a way that it is also suitable for receiving an X-ray tube.
PATENT CLAIMS:
1.High-voltage transformer, especially for portable small X-ray machines, with annularly arranged copper windings, the ring opening of which is filled with a central core made of sheet iron, which has the shape of a cylinder with flat base and top surfaces perpendicular to the axis of the cylinder and which, if necessary, carries the primary winding , characterized in that the magnetic circuit of the iron path is formed by U-shaped iron sheets which are twisted in such a way that their ends close together radially onto the windings
EMI2.1
lie on top of each other like roof tiles and with the exception of the places
at which the ends of the high voltage winding are led to the outside.
