PATENTAMT.PATENT OFFICE.

In Patent 152404 ist eine Einrichtung zum Ausgleich von Belastungsschwankungen beschrieben für Anlagen, in welchen mit Schwungmassen gekuppelte Wechselstromgleichstromumformer (Motorgeneratoren) verwendet werden. Hierbei wird eine in Abhängigkeit von der Stromstärke des Arbeitsmotors regelbare Selbstinduktionsspule in den Sekundäranker des stromaufnehmenden Teiles des Motorgenerators eingeschaltet, zum Zweck, die Schlüpfung desselben selbsttätig zu regeln. Bei dieser Einrichtung ist die Drosselwirkung lediglich abhängig von dem Arbeitsstrom , infolgedessen wird auch beim An- laufen, wo der Stromverbrauch groß ist, eine Drosselwirkung und Vermehrung der Schlüpfung eintreten, die nicht erwünscht ist. Denn da zu Anfang der Anlaßperiode die Klemmenspannung am Arbeitsmotor niedrig, die der konstanten Zugkraft entsprechende Stromstärke bis zum Ende der Beschleunigungsperiode nahezu konstant bleibt, so ist am Anfang der Anlaufperiode der Energiebedarf verhältnismäßig gering und steigt erst allmählich mit zunehmender Spannung bis zu seinem maximalen Wert. Eine starke Drosselwirkung und damit eine .Kraftabgabe der Schwungmassen sind also zu Anfang der Anlaßperiode nicht nötig und sogar unerwünscht.In patent 152404 there is a device for Compensation of load fluctuations is described for systems in which alternating current direct current converters are coupled with centrifugal masses (Motor generators) can be used. Here, one becomes dependent on the amperage of the working motor adjustable self-induction coil in the secondary armature of the current-consuming part of the motor generator switched on, for the purpose of regulating the hatching of the same automatically. With this device, the throttling effect is only dependent on the working current, as a result of which there is also run where the power consumption is high, a throttling effect and an increase in hatching occur, which is not desired. Because at the beginning of the starting period the terminal voltage on the working motor is low, which corresponds to the constant tensile force Current strength remains almost constant until the end of the acceleration period, so is at the beginning of the start-up period the energy requirement is relatively low and only increases gradually with increasing tension up to its maximum value. A strong choke effect and thus a .Kkraftabgabe the centrifugal masses are so at the beginning of the starting period not necessary and even undesirable.

Eine starke Drosselwirkung bei hohem Strom und niedriger Spannung kann nun nach vorliegender Erfindung dadurch vermieden werden, daß die gegengeschaltete Spule s2_(Fig. 1) nicht an eine im wesentlichen konstante Stromquelle, sondern parallel zum Anker des Arbeitsmotors gelegt wird. Spule ss führt, wie bei der Einrichtung nach Patent 152404, einen dem Hauptstrom proportionalen Strom. Legt man ein Energiediagramm zugrunde, wie es z. B. einer elektrisch betriebenen Förderanlage entspricht, so ändern sich die Amperewindungen in den gegeneinander geschalteten Spulen s2 und s8, etwa wie in den Kurven A W* und A W3 (Fig. 2) dargestellt ist. Die resultierenden Amperewindungen A Wr sind durch die Differenz A W3 AW1 gegeben.A strong choke effect at high current and low voltage can now be avoided according to the present invention in that the counter-connected coil s 2 _ (Fig. 1) is not connected to an essentially constant current source, but parallel to the armature of the working motor. As in the device according to patent 152404, coil s s carries a current proportional to the main current. If one takes an energy diagram as a basis, as it is z. B. corresponds to an electrically operated conveyor system, the ampere turns in the oppositely connected coils s 2 and s 8 change , roughly as shown in the curves AW * and AW 3 (FIG. 2). The resulting ampere turns A Wr are given by the difference AW 3 - AW 1 .

Die Wicklung sa erhält zunächst einen großen, später abnehmenden Strom, die Wicklung s2 einen im Anfange kleinen und allmählich steigenden Strom, so daß also die resultierende Amperewindungszahl der beiden Wicklungen während der Anlaufperiode im Anfang sehr groß und damit die Drosselwirkung klein wird. Allmählich, bei Zunähme der Spannung im Fördermotor wird die Drosselwirkung und damit die Schlüpfung der Maschine F vergrößert.The winding s a initially receives a large, later decreasing current, the winding s 2 a small and gradually increasing current at the beginning, so that the resulting number of ampere-turns of the two windings during the start-up period is very large at the beginning and thus the choke effect is small. Gradually, as the voltage in the conveyor motor increases, the throttling effect and thus the slippage of the machine F is increased.
