Description
Anordnung zum Regeln einer elektrischen lwlaschine mittels .einer Vakuumröhre. Die Erfindung bezieht sich auf eine Anordnung zum Regeln von elektrischen Maschinen mittels einer Vakuumröhre.Arrangement for controlling an electric machine by means of a Vacuum tube. The invention relates to an arrangement for regulating electrical Machines by means of a vacuum tube.
Zur Erläuterung des Erfindungsgedankens sind Zeichnungen beigefügt, die die Anwendung der Schaltung gemäß der Erfindung beispielsweise für eine Gleichstromnebenschlußmaschine veranschaulichen.Drawings are attached to explain the concept of the invention, the application of the circuit according to the invention for example for a DC shunt machine illustrate.
Abb i zeigt in schematischer Darstellung eine Schaltung zum Konstanthalten der Drehzahl eines Motors bei wechselnder Netzspannung, bei der der Glühfaden der Vakuumröhre parallel zum Netz liegt.Fig. I shows a schematic representation of a circuit for keeping constant the speed of a motor with alternating mains voltage at which the filament of the Vacuum tube is parallel to the network.
Abb 2 veranschaulicht eine ähnliche Schaltung, bei der der Glühfaden in der negativen Netzleitung liegt.Figure 2 illustrates a similar circuit in which the filament is in the negative power line.
a bedeutet den Anker der zu regelnden Maschine, b ihre Nebenschlußfeldwicklung und c die Vakuumröhre mit dem Glühfaden d und der Anode e. Der eine Pol des Glühfadens d ist in der Abb. i unter Zwischenschaltung eines Vorschaltwiderstandes f an die positive Netzleitung g1 angelegt, während der andere Pol des Glühfadens d unmittelbar an der negativen Netzleitung g2 liegt. In der Abb. 2 ist der Glühfaden d unmittelbar in die negative Netzleitung g2 eingeschaltet. Die Anode der Vakuumröhre ist über die Erregerwicklung b an die positive Klemme der Maschine angelegt. i bedeutet den Anlaßwiderstand, k einen Regulierwiderstand. I Die Wirkungsweise der Anordnung ist folgende: Bei normaler Netzspannung habe der I in der Wicklung b fließende Erregerstrom eine solche Größe, daß der Motor gerade die verlangte Drehzahl hat. Ändert sich nun die Netzspannung aus irgendwelchen Gründen, so ändert sich auch der Heizstrom für die Glühkathode d und somit auch die Elektrönenaussendung und der Erregerstrom der Maschine. Fällt z. B. die Netzspannung, sß wird auch der Heizstrom und somit der Anodenstrom der Röhre sinken; daraus ergibt sich eine Schwächung des Erregerfeldes. Es läßt sich nun erreichen, daß der durch die sinkende Netzspannung bedingte Abfall der Drehzahl gerade kompensiert wird durch die aus der Schwächung des Erregerfeldes sich ergebende Steigerung der Drehzahl.a means the armature of the machine to be controlled, b its shunt field winding and c the vacuum tube with the filament d and the anode e. One pole of the filament d is in Fig. i with the interposition of a series resistor f to the positive power line g1 applied, while the other pole of the filament d directly is on the negative power line g2. In Fig. 2, filament d is immediate switched into the negative power line g2. The anode of the vacuum tube is over the excitation winding b is applied to the positive terminal of the machine. i means that Starting resistance, k a regulating resistance. I The mode of operation of the arrangement is the following: At normal mains voltage, the I has excitation current flowing in winding b such a size that the engine has just the required speed. Changes if the mains voltage for whatever reason, the heating current also changes for the hot cathode d and thus also the emission of electrons and the excitation current the machine. For example B. the mains voltage, the heating current and thus also sweet the anode current of the tube will decrease; this results in a weakening of the excitation field. It can now be achieved that the drop caused by the falling mains voltage the speed is just compensated by the weakening of the excitation field resulting increase in speed.
