Description
Röntgeneinrichtung mit Umschaltung für Durchleuchtung und Aufnahme Es ist bereits eine Röntgeneinrichtung mit Umschaltung für Durchleuchtung und Aufnahme und hierfür vorgesehenen, zweckmäßig getrennt voneinander wirkenden Spannungsregelvorrichtungen bekannt geworden. Bei Verwendung von Mehrphasentransformatoren in einer derartigen Röntgeneinrichtung ergeben sich aber hinsichtlich der Ausbildung der Spannungsregelvorrichtungen Schwierigkeiten, wenn man eine Grob- und Feinregulierung mittels Anzapfungen an der Niederspannungswicklung des Transformators bei der einen Spannungsregulierung durchführen will.X-ray device with switchover for fluoroscopy and exposure It is already an X-ray device with switchover for fluoroscopy and exposure and voltage regulating devices which are provided for this purpose and which function separately from one another known. When using polyphase transformers in such a However, X-ray devices arise with regard to the design of the voltage regulating devices Difficulties if you have a coarse and fine adjustment by means of taps the low-voltage winding of the transformer in one voltage regulation want to perform.
Auch ist es bereits bekannt, bei Mehrphasen - Anzapftransformatoren zur Spannungsregelung sternpunktseitige Anzapfungen vorzusehen und den Sternpunkt mit Hilfe einer Schaltvorrichtung von Anzapfung zu Anzapfung zu verlegen.It is also already known in the case of multiphase tap transformers Taps on the star point side are to be provided for voltage regulation and the star point to be laid from tap to tap with the help of a switching device.
Erfindungsgemäß erfolgt bei einer Röntgeneinrichtung mit wahlweisem Betrieb für Durchleuchtung und Aufnahme die Umschaltung durch Verlegung des Sternpunktes in der Weise, daß eine Transformatorwicklung entsprechend den beiden Spannungsregelvorrichtungen in zwei Teile unterteilt ist und beide Teile über eine Schaltvorrichtung derart wahlweise verbunden werden, daß einmal der Sternpunkt an dem einen und das andere Mal an dem anderen Transformatorwicklungsteil vorhanden ist. Bei dieser Ausbildung ergibt sich der Vorteil, daß diejenige Spannungsregulierung, welche sich nicht der sternpunktseitig gelegenen Anzapfungen bedient, unabhängig wirken kann von derjenigen, die von diesen Anzapfungen Gebrauch macht.According to the invention, in the case of an X-ray device, optionally Operation for fluoroscopy and exposure switching by relocating the star point in such a way that a transformer winding corresponding to the two voltage regulating devices is divided into two parts and both parts via a switching device in such a way be optionally connected that once the star point at one and the other Times is present on the other transformer winding part. In this training there is the advantage that the voltage regulation which is not the taps located on the star point side operated, can act independently of the person who who makes use of these taps.
Vorteilhaft besteht die Umschaltvorrichtung aus einem einzigen Sternpunktumschaltschütz.The switching device advantageously consists of a single star point switching contactor.
In der Abbildung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt.In the figure, an embodiment according to the invention is shown.
Der Niederspannungswicklung I I des Hochspannungstransformators in der Durchleuchtungsstellung II des Umschalters 12 ist eine am Netz RST liegende, zweckmäßig kontinuierliche Regelungsvorrichtung 16 vorgeschaltet. Dabei wird dem Transformator die an den Klemmen der Regelungsvorrichtung abgenommene Spannung zugeführt. Der Sternpunkt der Niederspannungswicklung i i wird dabei durch die Schalterbrücken des Sternpunktumschaltschützes 2o in der gezeichneten Lage gebildet. Es sind zur Feineinstellung des t%ersetzungsverhältnisses besondere miteinander verkettete Windungen22 vorgesehen, die bei Aufnahme mit den Enden der offenen Niederspannungswicklungen i i über das Schütz 2o in der Schaltstellung I verbunden sind und deren Regelbürsten in den Sternpunktsverbindungen liegen. Die Sternpunktsverbindung wird wieder durch das Sternpunktumschaltschütz2o verlegt. Die Hochspannungswicklung ist mit 17 bezeichnet.The low voltage winding I I of the high voltage transformer in the fluoroscopic position II of the switch 12 is a connected to the network RST, expediently continuous control device 16 connected upstream. This is the Transformer is supplied with the voltage taken from the terminals of the control device. The star point of the low-voltage winding i i is created by the switch bridges of the star point changeover contactor 2o formed in the position shown. There are for Fine adjustment of the t% replacement ratio special interlinked windings22 provided that when recorded with the ends of the open low voltage windings i i are connected via the contactor 2o in the switch position I and their control brushes lie in the star point connections. The star point connection is through again the neutral point changeover contactor2o relocated. The high-voltage winding is denoted by 17.
Beim Umlegen des Umschalters 12 aus der Schaltstellung 0' in die Schaltstellung 0 wird über den Hiffskontakt 23 die Spule der Umschaltvorrichtung 2o erregt, so daß die Schalterbrücke die Enden der Wicklungsteile der Niederspannungswicklung unmittelbar miteinander verbindet. Die Spule des Umschaltschützes wird also erregt, bevor die Hochspannung eingeschaltet wird.When switching the switch 12 from the switch position 0 'to the switch position 0 the coil of the switching device is via the auxiliary contact 23 2o excited so that the switch bridge the ends of the winding parts of the low voltage winding connects directly with each other. The coil of the changeover contactor is thus excited before the high voltage is switched on.
Die Grobeinstellung bei der Spannungsregelung bei Aufnahme erfolgt mittels der an das Netz anzuschließenden Regelbürsten 13, die Feineinstellung mit den am Sternpunkt liegenden Regelbürsten der Windungen 22.The coarse adjustment for the voltage regulation during recording is carried out by means of the regulating brushes 13 to be connected to the network, the fine adjustment is carried out with the regulating brushes of the windings 22 located at the star point.
