Description

Induktivität Die Erfindung betrifft eine Anordnung zur Erzielung eines schnellen Anstieges des Verbraucherstromes beim Inbetriebsetzen von durch Gleichrichter gespeisten Verbrauchern großer Induktivität,beispielsweiseWirbelstromgleisbremsen.Inductance The invention relates to an arrangement for achieving a rapid increase in consumer current when starting up by rectifier fed consumers with high inductance, for example eddy current track brakes.

Es sind bereits Anordnungen zum Schnellanlassen und Umsteuern von Gleichstromelektromotoren bekanntgeworden, bei denen eine Anlaßmaschine vorgesehen ist, deren Gleichstromerregerwicklung für einen Teil der für die Erregung zur Verfügung stehenden Spannung bemessen ist, wobei die Überspannung durch einen Ohmschen Vorschaltwiderstand aufgenommen wird. Im Einschalteaugenblick, wo infolge der Gegenwirkung der Selbstinduktion der Erregerwicklung noch kein Strom im Erregerkreis fließt, liegt die ganze Spannung an der Erregerwicklung, und im Dauerzustand, wo die zeitlicha Änderung des Stromes den Wert Null hat, liegt ein großer Teil der Spannung am Vorschaltwiderstand, an der Erregerwicklung jedoch nur noch derjenige Bruchteil der gesamten Spannung, der für die Erregerwicklung im Dauerzustand vorgeschrieben ist.There are already orders for quick starting and reversing DC electric motors become known in which a starting machine is provided is whose DC excitation winding is available for part of the excitation standing voltage is measured, the overvoltage by an ohmic series resistor is recorded. At the moment of switching on, where as a result of the counteraction of self-induction the excitation winding has no current flowing in the excitation circuit, the full voltage is present on the excitation winding, and in the steady state, where the temporal change of the current has the value zero, a large part of the voltage is applied to the series resistor of the excitation winding, however, only that fraction of the total voltage that is prescribed for the excitation winding in the permanent state.

Gemäß der vorliegenden Erfindung werden zur Erzielung eines schnellen Anstieges des Verbraucherstromes beim Inbetriebsetzen von durch Gleichrichter gespeisten Verbrauchens großer Induktivität,beispelsweiseWirbelstromgleisbremsen, feste Anodendrosseln solcher Bemessung angeordnet, daß sie, solange ihr magnetisches: Feld noch nicht aufgebaut ist, praktisch keine Spannung, im Beharrungszustand dagegen die vom Gleichrichter abgegebene erhöhte Spannung ,auf den Betriebswert der Verbraucher abdrosseln.According to the present invention are to achieve a fast Increase in consumer current when starting up those fed by rectifiers Consumption of large inductance, for example eddy current track brakes, fixed anode chokes arranged in such a way that, as long as their magnetic: field is not yet is built up, practically no voltage, in the steady state, on the other hand, that of the rectifier output increased voltage, throttle down to the operating value of the consumer.

Bekanntlich wächst der induktive Widerstand einer solchen Anodendrosselspule ,erst mit der Zeit nach Maßgabe der zunehmenden Ausbildung des magnetischen Feldes auf den Dauerwert. Die festen Anodendrosseln vermögen also die ,erhöhte Verbrauchergleichspannung im Einschalteaugenblick bei Einwirkung des Belastungsstromes selbsttätig auf die gewünschte Dauerspannung abzudrosseln.It is known that the inductive resistance of such an anode choke coil increases , only over time in accordance with the increasing development of the magnetic field on the permanent value. The fixed anode chokes are therefore able to handle the increased DC consumer voltage automatically when the load current acts on the to throttle down the desired continuous voltage.
