Description

Schaltungsanordnung zur Regelung der Spannung von Wechselstromnetzen. Nach dem Hauptpatent 344725 wird die Regelung der Spannung von Wecihsclstromnetzen, die durch eine mit veränderlicher Geschwindigkeit laufende Maschine gespeist werden, dadurch herbeigeführt, daß vor den Verbraucher ein Wechselstromwiderstand aus Selbstinduktion und Kapazität geschaltet wird. Dieser Wechselstromwiderstand bildet mit steigender Wechselzahl und Spannung cler Maschine scheinbare Zusatzwiderstände und ist derart bemessen, daß die Nutzleistung der Maschine bei Geschw indigkeitsändei°ungen in weiten Grenzen konstant bleibt.Circuit arrangement for regulating the voltage of alternating current networks. According to the main patent 344725 the regulation of the voltage of Wecihsclstromnetz, fed by a machine running at variable speed, brought about by an alternating current resistance from self-induction in front of the consumer and capacity is switched. This alternating current resistance forms with increasing Alternation number and voltage of the machine are apparent additional resistances and is such dimensioned that the useful power of the machine with speed changes in remains constant over a wide range.

Das direkte Einschalten einer Kapazität in den Kreis hat unter Umständen den Nachteil, daß für nicht sehr hohe Periodenzahlen große Kondensatoren notwendig sind, um die Leistung aufnehmen zu können. Derartige Kondensatoren lassen sich nicht leicht herstellen, sind für manche Verwendungszwecke infolge ihrer Dimensionen ungünstig und ermöglichen vor allem nur eine ungünstige Ausnutzung des Dielektrikums, da man bei den großen notwendigen Flächen mit Materialfehlern rechnen muß und infolgedessen gezwungen ist, mit einem großen Sicherheitskoeffizienten gegen Durchschlagen zu rechnen. Diese ,nachteilige Notwendigkeit der Verwendung großer Kondensatoren läßt sich dadurch beseitigen, daß man nach dein Gegenstand der Erfindung nicht einen großen Kondensator direkt in den Kreis, sondern, wie in dem dargestellten Ausführungsbeispiel angedeutet, einen kleinen Kondensator n. mit einem Transformator b einschaltet. Gegenüber der an sich bekannten Verkleinerung eines Kondensators durch einen Transformator hat die Erfindung in Verbindung mit dem Gegenstand des Hauptpatents den Vorteil, daß im Belastungskreis selbst kein Kondensator liegt und der Kondensator wesentlich kleiner und mit stärkerem Dielektrikum getaut sein kann. Infolgedessen ist eine derartige Schaltungsanordnung wesentlich betriebsi'cherer und gestattet räumlich kleinere Abrnessungen, trotzdem ein Transformator benutzt wird.The direct connection of a capacity in the circuit has under certain circumstances the disadvantage that large capacitors are necessary for periods that are not very high are to be able to absorb the service. Such capacitors cannot be used easy to manufacture, are unfavorable for some purposes due to their dimensions and above all allow only an unfavorable utilization of the dielectric, since one must reckon with material defects in the large areas required and as a result is forced to have a large safety coefficient against penetration calculate. This objectionable necessity of using large capacitors eliminates the need eliminate yourself by not having one according to your subject matter of the invention large capacitor directly in the circuit, but, as in the illustrated embodiment indicated, a small capacitor n. turns on with a transformer b. Compared to the per se known reduction in size of a capacitor by a transformer the invention in connection with the subject matter of the main patent has the advantage that there is no capacitor in the load circuit itself and that the capacitor is essential can be thawed smaller and with a stronger dielectric. As a result, is a Such a circuit arrangement is much more operationally reliable and allows spatial smaller dimensions, despite the fact that a transformer is used.
