Description
Regelwandler mit in Stufen unterteilter Wicklung und einer zweiten, auf einem besonderen Schenkel des Eisenkerns angeordneten Wicklung für Gleitkontakte, der eine Ausgleichswicklung parallel geschaltet ist An ein Wechselstromnetz anzuschließende, zum Speisen verschiedener Stromkreise einer Anlage, z. B. einer Röntgeneinrichtung, dienende Regelwandler, die in Schaltpulte, Schalttische o. dgl. eingebaut werden und für die wenig Platz zur Verfügung steht, können nur für verhältnismäßig geringe Leistungen gebaut werden, vor allem wenn eine stetige Regelung vorgesehen ist und die Gleitbahn der Kontakte so lang als möglich sein soll. Denn in diesem Falle ergeben sich für den Eisenkern recht ungünstige Abmessungen. Ein Schenkelpaar wird sehr lang, die beiden zu ihnen senkrecht liegenden Schenkel dagegen werden kurz. Infolgedessen wird die Kraftlinienstreuung sehr erheblich. Dadurch wird die regelbare Leistung verringert, und es treten auch sonst durch die streuenden Kraftlinien Nachteile auf.Regulating converter with winding divided into steps and a second, winding arranged on a special leg of the iron core for sliding contacts, which has a compensating winding connected in parallel. for feeding various circuits in a system, e.g. B. an X-ray facility, Serving control converters, which are installed in control panels, switch tables or the like and for whom little space is available, can only be for relatively small Services are built, especially if a continuous regulation is provided and the sliding path of the contacts should be as long as possible. Because in this case surrender dimensions are quite unfavorable for the iron core. A pair of legs becomes very long, while the two legs perpendicular to them are short. Consequently the force line spread becomes very considerable. This makes the power controllable and there are other disadvantages due to the scattering lines of force on.
Es ist bei Transformatoren anderer Art üblich, die Streuungskraftlinien durch Ausgleichswicklungen (bisweilen auch Schubwicklungen genannt), die auf verschiedenen Schenkeln des Eisenkernes untergebracht und aufeinandergeschaltet sind, zu verringern. Dieses Mittel kann bei in beschränktem Raum unterzubringenden Regelwandlern nicht angewendet werden, da das Kernfenster zur Aufnahme der beiden Ausgleichswicklungen nicht groß genug ist.It is common with transformers of other types, the leakage force lines by compensating windings (sometimes also called thrust windings), which are based on different Legs of the iron core are housed and connected to one another to reduce. This means cannot be used with regulating converters that are to be accommodated in a limited space can be used as the core window to accommodate the two compensating windings is not big enough.
Erfindungsgemäß wird die auf dem einen Kern vorgesehene, als Gleitbahn dienende Regelwicklung selbst als Bestandteil der Ausgleichswicklung benutzt, indem dieser Regelwicklung eine ihr gleiche Wicklung auf dem anderen Schenkel parallel geschaltet und damit in' Reihe mit den Stufen der Grobregelung geschaltet wird.According to the invention, the one provided on one core is used as a slideway Serving control winding itself used as part of the compensation winding by this regular winding has a winding that is identical to it on the other leg in parallel switched and thus switched in 'series with the stages of the coarse control.
In der Abbildung ist beispielsweise der Erfindungsgegenstand schematisch dargestellt. Die strichpunktierte Linie deutet den Eisenkern i an. Auf dem einen Schenkel ist die Wicklung z mit Gleitbahnen für Kontakte 3, 4 angeordnet. Der andere Schenkel trägt zunächst eine ebensolche Wicklung 5, aber ohne Gleitbahnen, also isoliert, und darüber die in verschiedene Stufen unterteilte Wicklung 6. Die Gegenwicklung 5 liegt in Reihe mit den einzelnen Stufen der Wicklung 6; bei dem dargestellten Ausführungsbeispiel ist erstere in die Mitte geschaltet.In the figure, for example, the subject matter of the invention is schematic shown. The dash-dotted line indicates the iron core i. On the one Leg is the winding z with slideways for contacts 3, 4 arranged. The other Leg initially carries such a winding 5, but without slideways, that is insulated, and above it the winding 6, which is subdivided into different stages. The counter-winding 5 is in series with the individual stages of the winding 6; with the one shown Embodiment, the former is switched in the middle.
Bei Benutzung des beschriebenen Regelwandlers in Anlagen, in denen mehrere unabhängige Stromkreise zu speisen sind, werden zwei der Anzapfungen der Wicklungen 6 an das Netz angeschlossen, an die übrigen werden die einzelnen Stromkreise geschaltet, je nach der für diese benötigten Klemmenspannung. Diejenigen von diesen Stromkreisen, in denen eine Regelung der Klemmenspannung erforderlich ist, werden mit dem einen Pol an eine von den genannten festen Anzapfungen angeschlossen, mit dem anderen Pol an die verschiebbaren Bürsten 3 oder 4. Die beschriebene Anordnung ist also für den Anschluß von zwei derartigen Stromkreisen bestimmt. Bei Röntgenanlagen wären es der Heizstromkreis für die Röntgenröhre und zwecks Änderung der Röhrenspannung die Primärwicklung des Hochspannungstransformators, der die Röntgenröhre speist.When using the described control converter in systems in which If several independent circuits are to be fed, two of the taps become the Windings 6 are connected to the network, the individual circuits are connected to the rest switched, depending on the terminal voltage required for this. Those of these Circuits in which regulation of the terminal voltage is required with one pole connected to one of the fixed taps mentioned, with the other pole to the sliding brushes 3 or 4. The arrangement described is therefore intended for the connection of two such circuits. With X-ray systems it would be the heating circuit for the X-ray tube and for the purpose of changing the tube voltage the primary winding of the high voltage transformer that feeds the X-ray tube.
