Description
Einrichtung zur Regelung' von,-el.ekt;chen Maschinen und Apparaten Das Hauptpatent 604 057 betrifft die Regelung von elektrischen Maschinen und Apparaten mittels eines einzigen Reglers, der die besondere Eigenschaft besitzt, daß er bei Leerlauf auf Gleichheit zweier Spannungen, bei Belastung aber auf einen bestimmten einstellbaren Leistungsfaktor regelt.Device for the regulation of electrical machines and devices The main patent 604 057 relates to the regulation of electrical machines and devices by means of a single controller, which has the special property that it is on the equality of two voltages when idling, but when loaded regulates to a certain adjustable power factor.
Gemäß der Erfindung wird nun noch eine zusätzliche Vorrichtung vorgesehen, durch die bei Eintritt (elektrisch oder mechanisch) feststellbarer besonderer Betriebsverhältnisse der Regler selbsttätig wenigstens vorübergehend in einen gewöhnlichen Spannungsregler verwandelt wird, z. B. dann, wenn die betreffende Stromerzeugergruppe allein auf ein Netz arbeiten und daher die Spannung halten muß.According to the invention, an additional device is now provided, due to the special operating conditions that can be determined when the occurrence (electrical or mechanical) the regulator automatically at least temporarily into an ordinary voltage regulator is transformed, e.g. B. when the generator group in question is on alone a network must work and therefore maintain the voltage.
Der Gegenstand der Erfindung läßt sich beispielsweise wie in der Zeichnung in Anwendung zur Regelung eines bedienungslos laufenden Generators dargestellt ausführen.The object of the invention can be, for example, as in the drawing Execute shown in the application for the control of an unattended generator.
Der in der Figur schematisch dargestellte Regler i ist ein Gleichgewichtsregler. An jedem Ende eines Waagebalkens 16 greift ein Wattmetersystem an. Solange die beiden gemessenen Leistungen gleich groß sind, bleibt der Waagebalken in Ruhe. übersteigt die auf der einen Seite gemessene Leistung die der anderen Seite, so kippt der Hebel, und das Steuerorgan 9 wird im entsprechenden Sinne bewegt. Die Spannungsspulen 2 und 3 sind an verschiedene Phasen des Mehrphasennetzes (im Beispiel des Drehstromnetzes) angeschlossen, und zwar die Spule 2 über einen Wandler 6 vor dem Ölschalter z o, die Spule 3 über einen Wandler 7 nach dem Ölschalter i o. Die Stromspulen 4. und 5 sind vom selben Strom durchflossen, der vom Wandler 8 geliefert wird. Solange der Schalter io geöffnet ist, wirkt das Regelorgan als Differentialspannungsregler und reguliert den Regulator auf gleiche Spannung wie das Netz, auf das er geschaltet werden soll. Dabei ist es ganz ohne Einfuß, daß die beiden verglichenen Spannungen verschiedenen Phasen angehören, da der Vergleich mechanisch erfolgt.The controller i shown schematically in the figure is an equilibrium controller. A wattmeter system engages at each end of a balance beam 16. As long as the two measured power are the same, the balance beam remains at rest. exceeds the power measured on one side is that of the other side, the lever tilts, and the control element 9 is moved in the corresponding sense. The voltage coils 2 and 3 are connected to different phases of the multi-phase network (in the example of the three-phase network) connected, namely the coil 2 via a converter 6 in front of the oil switch z o, the coil 3 via a converter 7 after the oil switch i o. The current coils 4. and 5 are traversed by the same current that is supplied by converter 8. So long the switch io is open, the control element acts as a differential voltage regulator and regulates the regulator to the same voltage as the network to which it is connected shall be. It is entirely without influence that the two tensions compared belong to different phases, since the comparison is made mechanically.
Eine Feder 23 zieht einen Hebel 24 nach oben bis zu einem Anschlag 25. Dadurch ist die Feder 28, welche sich auf dem Waagebalken 16 abstützt und eine Stange des Hebels 24 trägt, unwirksam. Der Regler arbeitet dann wie im Hauptpatent beschrieben. Wird nun bei Eintritt eines bestimmten Betriebszustandes die Spule 27 erregt, so bewegt sich der Hebel 24 nach unten bis zum Anschlag 26, wodurch der Regler mit der Feder 28 belastet wird und die Spannungsspule 3 sowie die Stromspule 4 und 5 abgeschaltet werden.A spring 23 pulls a lever 24 up to a stop 25. This is the spring 28, which is supported on the balance beam 16 and a Rod of the lever 24 carries, ineffective. The controller then works as in the main patent described. When a certain operating state occurs, the coil 27 excited, the lever 24 moves down to the stop 26, whereby the Controller is loaded with the spring 28 and the voltage coil 3 and the current coil 4 and 5 are switched off.
