Description
Relaislose Einrichtung zur selbsttätigen Spannungsregelung in Wechselstromnetzen ' mittels Regeltransformatoren Das Hauptpatent 700 151 betrifft eine relaislose Einrichtung zur selbsttätigen Spannungsregelung in Wechselstromnetzen mittels Regeltransformatoren, bei welcher der Regelmotor, der 'über ein spannungsabhängiges, den Motor bei einer bestimmten Sollspannung, stillsetzendes Widerstandsgebilde an das zu regelnde Netz angeschlossen ist, bei Spannungsänderungen, die den Regelbereich der Einrichtung überschreiten, dadurch zum Stillstand gebracht wird, daß; durch die Reglerverstellvorrichtung (Anzapfschalter) in den Endstellungen mit Hilfe von zusätzlichen Widerständen im spannungsabhängigen Widerstandsgebilde :eine solche Veränderung der elektrischen Werte seiner Elemente vorgenommen wird, daß, die .gleichen .elektrischen Verhältnisse ,auftreten wie beim Erreichen der Sollspannung.Relayless device for automatic voltage regulation in alternating current networks' by means of regulating transformers The main patent 700 151 relates to a relayless device for automatic voltage regulation in alternating current networks by means of regulating transformers, in which the regulating motor, the '' via a voltage-dependent resistor structure that shuts down the motor at a certain setpoint voltage, is connected to the one to be regulated Network is connected, is brought to a standstill in the event of voltage changes that exceed the control range of the device in that; through the regulator adjusting device (tap switch) in the end positions with the help of additional resistors in the voltage-dependent resistor structure: the electrical values of its elements are changed in such a way that the same electrical conditions occur as when the nominal voltage is reached.
Gemäß, der Erfindung werden die zusätzlichen Widerstände durch von der Reglerverstellvorrichtu.ng (Anzapfschalter) in den Endstellungen betätigte Schalter kurzgeschlossen oder in Wirksamkeit gesetzt. Vorzugsweise wird die Einrichtung derart getroffen, daß diese Schalter zugleich als abgefederte Endanschläge für die Reglerverstellvorrichtung (Anzapfschalter) ausgebildet sind.According to the invention, the additional resistances are provided by from of the regulator adjustment device (tapping switch) in the end positions operated switches short-circuited or activated. Preferably the device is of this type made that these switches also act as cushioned end stops for the regulator adjustment device (Tap switch) are formed.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. In Abb. 1 besteht das spannungsabhängige Widerstandsgebilde, das einerseits mit dem nicht dargestellten Netz und andererseits mit dem ebenfalls nicht gezeichneten Regelmotor in Verbindung steht, aus einer gesättigten. Eisendrossel i und einem Kondensator 2 i141 Parallelschaltung. Im induktiven wie atrcai= im kapazitiven Zweig des Steuerkreises sitd`: Ohmsche Widerstände 3 vorgesehen, die ä111. Ende des Regelbereichs durch die Schalter 4. in Wirksamkeit gebracht werden, wodurch eine solche Veränderung der an dem Widerstandsgebilde liegenden Spannung bewirkt wird, daß. der Regelmotor zum Stillstand kommt.The drawing shows an exemplary embodiment of the subject matter of the invention shown. In Fig. 1 there is the voltage-dependent resistance structure, on the one hand with the network not shown and on the other hand with the also Not shown control motor is connected, from a saturated. Iron throttle i and a capacitor 2 i141 parallel connection. In inductive like atrcai = in capacitive Branch of the control circuit sitd`: Ohmic resistors 3 provided, the ä111. end of the control range can be brought into effect by the switch 4 causes such a change in the voltage applied to the resistor structure will that. the control motor comes to a standstill.
Abb.2 zeigt ein Ausführungsbeispiel des Erfindungsegenstandes, bei dem die Schalter 4. selbst' oder ihre Antriebsvorrichtung zugleich .als abgefederte Endschläge ausgebildet sind. Dies hat den Vorteil, daß durch Zusammenwirken der beweglichen Teile der Endanschläge und der in der Endstellung dagegen anlaufenden Antriebsteile des Reglers das Gegendrehmoment am Ende durch die Federn allmählich erhöht wird, so daß Stöße im Getriebe vermieden werden.Fig.2 shows an embodiment of the subject matter of the invention which the switch 4. itself 'or its drive device at the same time .als sprung End strokes are formed. This has the advantage that the interaction of the moving parts of the end stops and those in the end position, however, starting Drive parts of the governor gradually increase the counter torque at the end through the springs is increased so that shocks in the transmission are avoided.
In der Abb.2 sind 5 die beiden durch Federn G abgefederten Endanschläge, zwischen denen sich ein Arm 8 der nur angedeuteten Reglerverstellvorrichtung 9 bewegt. Die festen Stücke 7 können die Schalter nach Abb. i darstellen. Sie können aber auch dazu dienen, über ein Gestänge diese Schalter zu betätigen.In Fig. 2, 5 are the two end stops cushioned by springs G, between which an arm 8 of the only indicated controller adjusting device 9 moves. The fixed pieces 7 can represent the switches according to Fig. I. But you can also serve to operate these switches via a linkage.
Das Wiederanlaufen des Regelmotors aus den Endstellungen heraus kann z. B. dadurch ermöglicht werden, daß geeignet geschaltete Hilfswandler in dem Widerstandsgebilde eine das Anlaufen des Motors in dem richtigen Drehsinn bewirkende Zusatzspannung hervorrufen, wobei dann gleichzeitig mit dem Anlauf des-Motors die überbrückung des bis dahin eingeschalteten Widerstandes erfolgt.The restart of the control motor from the end positions can z. B. be made possible that suitably switched auxiliary transducers in the resistor structure an additional voltage causing the motor to start in the correct direction of rotation cause, in which case the bypass occurs at the same time as the motor starts up of the resistor that has been switched on up to that point.
