Description
Für Sonderzwecke. beispielsweise für Gleichstromprüfanlagen oder auch für Gasreinigungsanlagen, sind Hochspannungsgleichrichteranordnungen _ bekanntgeworden, bei denen Kondensatoren über Gleichrichterventile aus einem Wechselstromnetz aufgeladen werden und bei denen diese Ladung dann an den Verbraucher abgegeben wird. Eine zu dieser Gruppe von Hochspannungsgleichrichteranordnungen gehörige bekannte Schaltung verwendet mehrere Paare von Gleichrichterventilen und Kondensatoren. Die Ventile und die Kondensatoren sind sämtlich in Reihe geschaltet, und die Enden der Ventile und Kondensatoren sind abwechselnd unmittelbar und unter Zwischenschaltung von in der Phase gegeneinander verschobenen Wechselspannungen verbunden. Die Wechselspannungen «-erden zweckmäßig der Sekundärseite eines Transformators entnommen. der primärseitig an ein normales Drehstromnetz angeschlossen ist.For special purposes. for example for DC test systems or also for gas cleaning systems, high-voltage rectifier arrangements have become known, in which capacitors are charged from an alternating current network via rectifier valves and in which this charge is then given to the consumer. One to known circuit belonging to this group of high-voltage rectifier arrangements uses multiple pairs of rectifier valves and capacitors. The valves and the capacitors are all connected in series, and the ends of the valves and capacitors are alternately direct and with the interposition of in the phase mutually shifted alternating voltages connected. The alternating voltages «- earth is expediently taken from the secondary side of a transformer. the primary side is connected to a normal three-phase network.
Gemäß der Erfindung wird bei dieser letztgenannten Gleichrichterschaltung der belastungsabhängige Spannungsabfall dadurch vermindert, daß auf der Primärseite des die Gleichrichteranordnung speisenden Transformators Drosselspulen vorgeschaltet sind. Versuche haben gezeigt, daß diese Drosselspulen der Umformeranordnung eine Strom-Spannungs-Kennlinie ergeben, bei der die Spannung mit zunehmender Belastung außerordentlich viel weniger absinkt. als es bei bekannten Anordnungen der Fall ist.According to the invention, this last-mentioned rectifier circuit the load-dependent voltage drop is reduced by being on the primary side of the transformer feeding the rectifier arrangement, inductors are connected upstream are. Experiments have shown that these reactors of the converter assembly a Current-voltage characteristics result in which the voltage increases with increasing load much less subsides. than is the case with known arrangements is.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schaltungsschema dargestellt. An ein Drehstromnetz 1 ist über einen Schalter 2 ein Transformator angeschlossen, dessen Primärwicklung 3 aus drei in Dreieck geschalteten Phasenwicklungen besteht. Jede der drei Sekundärwicklungen 4, 3 und 6 ist in der bekannten Delon-Schaltung über zwei Ventile mit zwei Kondensatoren verbunden: sämtliche Kondensatoren und sämtliche Ventile sind in Reihe geschaltet; an die Enden dieser Reihenschaltung ist der Verbraucher in Form eines Widerstandes, angeschlossen. Bis dahin ist die Schaltung an sich bekannt.In the drawing, an embodiment of the invention is shown in the circuit diagram. A transformer is connected to a three-phase network 1 via a switch 2, the primary winding 3 of which consists of three phase windings connected in delta. In the known Delon circuit, each of the three secondary windings 4, 3 and 6 is connected to two capacitors via two valves: all the capacitors and all the valves are connected in series; the consumer in the form of a resistor is connected to the ends of this series circuit. Until then, the circuit is known per se.
Erfindungsgemäß wird diese L'mformeranordnung dadurch verbessert. daß in die Primärleitung des Transformators Drosselspulen e geschaltet sind. die dafür sorgen. daß der belastungsabhängige Spanungsabfall kleiner wird. Rüstet man in an sich bekannter Weise die Drosselspulen 8 noch mit regelbarer Gleichstromerregung aus. so läßt sich der Spannungsabfall noch weiter Herabsetzen oder ganz beseitigen.According to the invention, this mold arrangement is improved as a result. that inductors e are connected in the primary line of the transformer. the ensure. that the load-dependent voltage drop becomes smaller. One equips in a manner known per se, the choke coils 8 still have controllable direct current excitation the end. in this way, the voltage drop can be further reduced or eliminated entirely.
