Description
Es ist bekannt, daß man Wechselstromsynchrongeneratoren kompoundieren kann, indem man die Erregermaschine mit einer besonderen Kompoundwicklung versieht, die man über Stromwandler und Gleichrichter vom Laststrom abhängig speist. Diese Schaltung erfordert aber für die Erregermaschine eine Sonderausführung mit zwei Feldwicklungen und ist daher bei bereits fertigen MaschinenIt is known to use alternating current synchronous generators can compound by using the exciter with a special Compound winding is provided, which is fed via current transformers and rectifiers depending on the load current. This circuit but requires a special design with two field windings for the exciter and is therefore in the case of machines that have already been completed
ίο nicht mehr anzuwenden.ίο no longer to be used.
Die Erfindung ermöglicht es nun, jeden Wechselstromgenerator mit selbsterregter mehrpoliger Erregermaschine -mit Wellenwicklung im Läufer zu kompoundieren, ohne daß deren Wicklung verändert wird.The invention now makes it possible to use any alternator with self-excited multipole exciter -with wave winding in the rotor to compound without that their winding is changed.
Zu diesem Zweck wird das Magnetfeld derFor this purpose, the magnetic field is the
■ Erregermaschine des Generators durch Abschalten eines Teiles der Pole und Anschließen der verbleibenden Pole an die Klemmen der -' Erregermaschine unsymmetrisch erregt, das heißt es werden die abgeschalteten Pole nur als Folgepole durch die eingeschalteten Spulen miterregt, aber erheblich schwächer. Dieses ■ unsymmetrische Feld erzeugt eine entsprechend verminderte Ankerspannung, die sofort ansteigt, wenn an den abgeschalteten Polen ganz geringe zusätzliche Erregerkräfte auftreten. Den abgeschalteten Polen wird nun in an sich bekannter Weise über Stromwandler und Gleichrichter ein dem Belastungsstrom verhältnisgleicher Strom zugeführt, wodurch die Symmetrie des Magnetfeldes wiederhergestellt wird.■ Exciter machine of the generator by switching off part of the poles and connecting of the remaining poles to the terminals of the - 'excitation machine excited asymmetrically, the it means that the switched-off poles are only followed by the switched-on coils also excited, but considerably weaker. This ■ asymmetrical field generates a corresponding Reduced armature voltage, which increases immediately when applied to the disconnected poles very little additional excitation forces occur. The disconnected Poland is now in a manner known per se via current transformers and rectifiers to the load current proportional current supplied, whereby the symmetry of the magnetic field is restored.
Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist A der Anker der vierpoligen Erregermaschine, die ihre drei Magnetspulen i, 2 und 3 in bekannter Weise im Nebenschluß erregt, so daß in dem Polgehäuse ein aus drei Polen bestehendes unsymmetrisches Feld entsteht. Die Spule 4 wird in an sich bekannter Weise über Stromwandler und Gleichrichter an den Hauptstromkreis des Wechselstromgenerators Ge angeschlossen. Erst wenn ein zusätzlicher Erregerstrom die Spule 4 durchfließt, wird das gesamte Magnetfeld symmetrisch; es steigt damit die Anker spannung und steuert die Stammspulen ι, 2 und 3 selbst.In the embodiment shown in the drawing, A is the armature of the four-pole excitation machine, which excites its three magnet coils i, 2 and 3 in a known manner in a shunt, so that an asymmetrical field consisting of three poles is created in the pole housing. The coil 4 is connected in a manner known per se to the main circuit of the alternator Ge via current transformers and rectifiers. Only when an additional excitation current flows through the coil 4 does the entire magnetic field become symmetrical; it increases the armature voltage and controls the main coils ι, 2 and 3 itself.
St ist der Stromwandler, Gl der Gleichrichter, E das Polrad des Generators und N, ein Regelwiderstand für die Nebenschlußerregung der Erregermaschine. St is the current transformer, Gl is the rectifier, E is the generator's pole wheel and N is a variable resistor for the shunt excitation of the exciter.
