GlühkathodenröhrenHot cathode tubes
Die Erfindung betrifft eine elektrische Einrichtung zum Betrieb von Röntgen- und anderen Glühkathodenröhren mit zwei primär und sekundär hintereinandergeschalteten Transformatoren, von denen der eine kathoden- und der andere anodenseitig an die Röhre angeschlossen und mindestens einer mit einer Heizstromwicklung zur Beheizung der Glühkathode versehen ist.The invention relates to an electrical device for operating X-ray and other hot cathode tubes with two primary and secondary transformers connected in series, one of which is on the cathode side and the other on the anode side connected to the tube and at least one with a heating current winding for heating the hot cathode is provided.
Bei solchen Einrichtungen ist es bekannt, den gemeinsamen Punkt und die Außenpunkte der Primärwicklungen je an eine von drei Anzapfstellen eines Regeltransformators anzuschließen und mindestens zwei dieser Anzapfstellen so einstellbar anzuordnen, daß jede der Spannungen über die Primärwicklungen der Transformatoren für sich geregelt werden kann.In such facilities it is known to have the common point and the external points of the Primary windings each to be connected to one of three taps of a regulating transformer and to arrange at least two of these taps so adjustable that each of the voltages over the Primary windings of the transformers can be regulated individually.
Bei dieser Schaltung konnten zwar die für sich regelbaren Primärspannungen der beiden Transformatoren addiert werden, es war aber nicht möglich, diese Spannungen gegeneinander zu schalten.With this circuit, the independently controllable primary voltages of the two transformers can be added, but it was not possible to switch these voltages against each other.
Die Erfindung bezweckt die Beseitigung dieses Mangels durch Anwendung von Mitteln, die bei der Regelung der Röhrenspannung eine Gegeneinanderschaltung der je für sich geregelten Primärspannungen der Transformatoren bewirken.The invention aims to remedy this deficiency by using means that in the Regulation of the tube voltage a counter-connection of the primary voltages, each independently regulated of the transformers.
Zu diesem Zweck wird vorteilhaft von einer an sich bekannten Einrichtung, bei welcher der eine Außenpunkt der Primärwicklungen mit einem Gleit-For this purpose is advantageous from a known device in which the one Outer point of the primary windings with a sliding

kontakt am Regeltransformator verbunden ist, Gebrauch gemacht, aber erfindungsgemäß mit der Maßgabe, daß auch der gemeinsame Punkt mit einem Gleitkontakt verbunden ist, und beide Gleitkontakte aneinander vorbeigeführt werden können. Weiter gibt die Erfindung die Möglichkeit, bei an sich bekannter Verbindung des gemeinsamen Punktes mit einem festen Anzapfpunkt am Regeltransformator die Anordnung so zu treffen, daß ίο dieser Anzapfpunkt von den Enden des Regel transformators entfernt liegt und mindestens einer der einstellbaren Anzapfpunkte an ihm vorbeibewegt werden kann.contact is connected to the regulating transformer, made use, but according to the invention with the Provided that the common point is also connected to a sliding contact, and both sliding contacts can be led past each other. The invention also gives the possibility of known connection of the common point with a fixed tapping point on the regulating transformer Make the arrangement in such a way that ίο this tapping point from the ends of the rule transformer away and at least one of the adjustable tapping points moves past it can be.
Einzelheiten ergeben sich aus der nachstehenden Beschreibung und aus der Zeichnung, in der in Fig. ι und 2 zwei Ausführungsbeispiele der Erfindung schematisch dargestellt sind.Details result from the following description and from the drawing in which in Fig. Ι and 2 two embodiments of the invention are shown schematically.
Die elektrische Einrichtung nach der Erfindung dient gemäß der Zeichnung zum Betrieb einer Röntao . genröhre ι oder einer anderen Glühkathodenröhre mit Glühkathode 2 und Anode 3 sowie zwei Transformatoren 4 und 5, deren Sekundärwicklungen Hochspannung an die Röhre ι liefern und von denen mindestens der eine (4) mit einer Heiz-Stromwicklung 6 zur Beheizung der Glühkathode 2 versehen ist. Die Primärwicklungen der Transformatoren 4, 5 haben einen gemeinsamen Punkt 7, und ihre Außenpunkte 9 und 10 sind mit einem Regeltransformator 8 verbunden, der bei 11 und 12 an ein Starkstromnetz angeschlossen ist.According to the drawing, the electrical device according to the invention is used to operate a X-ray unit . genröhre ι or another hot cathode tube with hot cathode 2 and anode 3 and two transformers 4 and 5, the secondary windings of which supply high voltage to the tube ι and of which at least one (4) with a heating current winding 6 for heating the hot cathode 2 is provided. The primary windings of the transformers 4, 5 have a common point 7, and their outer points 9 and 10 are connected to a regulating transformer 8, which is at 11 and 12 is connected to a power network.
Der gemeinsame Punkt 7 ist an eine Anzapfstelle 13 des Regel transformator s 8 angeschlossen, und die Abstände der Anzapfstelle 13 von den Anschlußstellen 14, 15 der Außenpunkte 9, 10 sind veränder-Hch. The common point 7 is connected to a tap 13 of the control transformer s 8, and the distances of the tap 13 from the connection points 14, 15 of the outer points 9, 10 are variable-Hch.
Bei dem in Fig. 1 dargestellten Beispiel bestehtIn the example shown in Fig. 1, there is
die Anzapfstelle 13 aus einem Gleitkontakt am ■ Regeltransformator 8, ebenso die Anzapfstelle 14 des Außenpunktes 10. Die beiden Gleitkontakte 13the tapping point 13 from a sliding contact on the control transformer 8, as is the tapping point 14 of the outer point 10. The two sliding contacts 13
und 14 sind in je einer senkrecht zu den Wicklungsdrähten des Regeltransformators 8 liegenden Ebene angeordnet und unabhängig voneinander einstellbar.and 14 are each one perpendicular to the winding wires of the regulating transformer 8 lying level arranged and independently adjustable.
Bei dem Beispiel nach Fig. 2 sind beide Außenpunkte 9, 10 an je einen am Regeltransformator verstellbaren Gleitkontakte 14, 15 angeschlossen.In the example according to FIG. 2, both outer points 9, 10 are each one on the regulating transformer adjustable sliding contacts 14, 15 connected.
Die Anzapfstelle 13 ist bei dieser Ausführungsform zwecks Vereinfachung als eine feste Verbin dung zwischen dem gemeinsamen Punkt 7 und dem Regeltransformator 8 ausgebildet, kann aber auch mit einem Gleitkontakt nach Art des in Fig. 1 dargestellten versehen sein.The tapping point 13 is in this embodiment for the sake of simplicity as a fixed connection Formation between the common point 7 and the regulating transformer 8, but can also with a sliding contact of the type shown in FIG be provided.
