Description

Anordnung zur Regelung der von gittergesteuerten Quecksilberdampfgleichrichtern abgegebenen Gleichspannung Zusatz zum Patent 678 Siz Gegenstand des Hauptpatents 678812 ist eine Anordnung zur Regelung der von gittergesteuerten Quecksilberdampfgleiohrichtern abgegebenen Glechspannungdurch Änderung der resultierenden Erregung der mit zwei Prim.ärwzcklungen je Phase ausgestatteten Gittertransformatoren, darin bestehend, daß die beiden jeder Phase zugeordneten Primärwicklungen des Gittertransformators von je einer anderen Phase eines in der Phasenzahl mit dem zu steuernden Hauptgleichrlchter übereinstimmenden Hilfstransformators über Widerstände und Hilfsgleichrichter mit Strömen veränderbarer Größe gespeist werden und daß -die Veränderung der Größe .der Erregerströme dadurch erfolgt, daß der zum neutralen Punkt des Hilfstransformators führende Abgriff an einem Widerstand, welcher die neutralen Punkte der beiden Prmärwicklungssysteme miteinander verbindet, verschoben wird.Arrangement for controlling the output from grid-controlled mercury arc rectifiers DC voltage addition to Patent 678 Siz subject of the main patent 678 812 an arrangement for regulation of the output of grid controlled Quecksilberdampfgleiohrichtern Glechspannungdurch is modification of the resulting excitation of each phase equipped with two Prim.ärwzcklungen grid transformers, consisting in the fact that the two Primary windings of the grid transformer assigned to each phase are fed by a different phase of an auxiliary transformer whose number of phases corresponds to the main rectifier to be controlled via resistors and auxiliary rectifiers with currents of variable size and that the change in size of the auxiliary transformer leading tap on a resistor, which connects the neutral points of the two primary winding systems with each other, is shifted.

Erfindungsgemäß wird diese Anordnung dadurch verbessert, daß an jeden Sternpunkt der in zwei phasenzahlgleche, sterngesichaltete Gruppen unterteilten Primärwicklungen der Gittextransformatoren ein Widerstand einpolig angeschlossen ist, dex über einer verstellbaren Gleitkontakt den Sekundärstromkreis des Hilfstransformators über die Hilfsgleichrichter, das eine Primärwichlungssystem der Gittertransformatoren und eine die Gittervorspannung erzeugende Gleichspannungsquelle schließt, und daß sichließlich die beiden Widerstände oder ihre Kontaktbahnen räumlich derart hintereinander angeordnet sind, daß bei einer Verschiebung des Gleitkontaktes von .einer Extremlage zur anderen zuerst nur der eine Widerstand und hernach nur der andere Widerstand von dem Gleitkontakt berührt wird, und daß -sich durch die Verschiebung des Gleitkontaktes über die Widerstände eine stetige Regelung der vorn Hauptgleichrichter abgegebenen Gleichspannung ergibt.According to the invention this arrangement is improved in that to each Star point divided into two groups with the same number of phases Primary windings of the Gittex transformers are connected to a single pole resistor is, dex the secondary circuit of the auxiliary transformer via an adjustable sliding contact via the auxiliary rectifier, which is a primary winding system for the grid transformers and a DC voltage source generating the grid bias closes, and that finally the two resistors or their contact tracks spatially in such a way one behind the other are arranged that with a displacement of the sliding contact from .einer extreme position on the other hand only one resistance at first and then only the other resistance is touched by the sliding contact, and that by the displacement of the sliding contact Continuous regulation of the main rectifier output via the resistors DC voltage results.

Die Verbesserung des Gegenstandes des Hauptpatents durch den Gegenstand gemäß dar Erfindung besteht darin, daß die Regelgrenzen mit Leichtigkeit und ohne Zuhilfena'hme zusätzlicher- Vorrichtungen erweitert werden können. Man erhält somit lediglich durch eine geeignete Anordnung und Schaltung der Teile des Gegenstandes des Haupt-Patents eine weitere Reg@elung.snzöglidhket.The improvement of the subject matter of the main patent through the subject matter according to the invention is that the control limits with ease and without Additional devices can be expanded. One thus obtains only through a suitable arrangement and switching of the parts the subject of the main patent is another Reg@elung.snzöglidhket.

Die Erfindung wird machstehend an Hand des in Ab-b. i dargestellten Ausführungsbeispiels erläutert, wobei für gleiche Teile die gleichen Bezugszeichen Verwendung find. w@e in der Zeichnung des Hauptpatents.The invention is illustrated by means of the in Ab-b. i illustrated Embodiment explained, wherein the same reference numerals for the same parts Use find. w @ e in the drawing of the main patent.

Wie bei,der Einrichtung nachdem Hauptpatent finden Transformatoren 7 mixt zwei P 'nmärwncklungen a und b Verwendung. Die nicht mir den Widerständen 8 verbundenen Enden der Wicklungen a sind an einte Klemme C eines Widerstandes CH angeschlossen; dessen Element DH einen Teil eines Schiebewiderstandes 23 bildet, während die Enden der nicht mit den Widerständen. 9 verbundenen Wicklungen b mit einer Klemme A ,eines Elements AB in Verbindung stehen, das dem Element CH des gleichen Schiebewiderstandes 23 ähnlich ist. Bekanntlich werden die die Wicklungen a durchfließenden Ströme gegenüber den Strömen, die die Wicklungen b durchfließen, um einen konstanten Wert von 6o elektrischen Graden verschoben. Eine die negative Polarisation der Gitter liefernde Gleichsspannungsquelle 24 ist in den Lieferstromkreis der Gleicbrichterelemente i o eingeschaltet, wie dies Abb. i zeigt. Der von den. Elementen i o in die Wicklungen b gelieferte Strom nimmt beim Verschieben des Läufers des Widerstandes 23 von B nach A nacheinander die Form -e, f und schließlich die Form g gemäß Abb. 2 an, wodurch eine Verschiebung des Zündpunktes der entsprechenden Anode um 120 elektrische Grade stattfindet.As in the case of the device according to the main patent, transformers 7 mix two primary windings a and b. The ends of the windings a not connected to the resistors 8 are connected to one terminal C of a resistor CH ; whose element DH forms part of a sliding resistor 23, while the ends of the not with the resistors. 9 connected windings b are connected to a terminal A , an element AB, which is the element CH of the same slide resistor 23 is similar. As is known, the currents flowing through the windings a are shifted by a constant value of 60 electrical degrees compared to the currents flowing through the windings b. A DC voltage source 24, which supplies the negative polarization of the grid, is switched into the supply circuit of the rectifier elements, as shown in FIG. The one from the. The current supplied to elements io in the windings b assumes the form -e, f and finally the form g according to Fig. 2 when the rotor of the resistor 23 is moved from B to A, which shifts the ignition point of the corresponding anode by 120 electrical degrees takes place.

Wenn der Punkt D des Widerstandes CH derart gewählt ist, daß der die Wicklung a durchfließende Strom die durch die Kurve! der A b. 2 gezeigte Form hat, so sieht man, daß der in der Sekundärwicklung c erzeugte Innpuls im gleichen Augenblick auftritt, wenn der Läufer des Schieb@ewiderstandeS 23 sich im Punkt B oder im Punkt D befindet. Ferner bewirkt eine Verschiebung dieses Läufers von D nach H bekanntlich eine Verformung der Kurve des die Wicklunga durchfließenden Stromes, so rufe dies die punktierten Kurven i und h der Abb. 2 entsprechend den Stellungen D und H des Läufers auf dem Schiebewiderstand 23 zeigen. Man bewirkt also auf diese Weise eine Verschiebung des Zündpunktes um 6o° .durch dem WiderstandHD und um 12o° durch den WiderstandBA. Eine derartige Regelung erlaubt also eine Vers biebungdes Zündpunktes um i8o°. Sollte dieser Regelbereich noch ungenügend ein, s3 ist es leicht, ihn auf 2q.0° und mehr zu erwiextern, indem man den Teil CD des Widerstandes CH benutzt und die Wicklungen a und b der Transformatoren 7 von Strömen .durchfließen läßt, die um 120 elektrische Grade verschoben sind.If the point D of the resistor CH is selected such that the current flowing through the winding a corresponds to the curve! the A b . 2, it can be seen that the pulse generated in the secondary winding c occurs at the same instant when the rotor of the sliding resistor 23 is in point B or in point D. Furthermore, as is known, a displacement of this rotor from D to H causes a deformation of the curve of the current flowing through the winding a, this is what the dotted curves i and h in Fig. 2 show corresponding to the positions D and H of the rotor on the sliding resistor 23. In this way the ignition point is shifted by 60 ° through resistor HD and by 120 ° through resistor BA. A regulation of this type therefore allows the ignition point to be shifted by 180 °. If this control range is still insufficient, s3 it is easy to expand it to 2q.0 ° and more by using the part CD of the resistor CH and allowing currents to flow through the windings a and b of the transformers 7, which are around 120 ° electrical degrees are shifted.

Es liegt auf .der Hand, daß jede Abänderung des oben beschriebenen Ausführungsbeispiels, sofern dadurch an dem Wirkungspznzip nichts geändert wird, in den Rahmen der Erfindung fällt.It is obvious that any modification of the above Embodiment, provided that nothing is changed in the effect principle, falls within the scope of the invention.
