Description

Verfahren zur Uberlagerung von zwei gegebenenfalls asynchron betriebenen Netzteilen oder Sammelschienen mit von einem umlaufenden Impulsgeber gesteuerten Tonfrequenzimpulsen Die Elektrizitätsversorgungsunternehmen sind in steigendem Maße bestrebt, bestimmte Verbrauchergruppen, wie Straßenlampen, Wasserspeicher u. dgl., von einer zentralen Stelle aus mittels einer Fernsteueranlage ein- und auszuschalten. An dieser zentralen Stelle ist ein Tonfrequenzsender vorhanden, dessen Frequenz impulsmäßig im Takt der vorgesehenen Kommandos dem Netz aufgedrückt wird. Sowohl im Sender als auch bei den Empfängern werden meist synchron umlaufende Wähler benutzt, die nach dem Start-Stopp-Prinzip arbeiten und die zur Einhaltung des notwendigen Gleichlaufs mittels Synchronmotoren angetrieben werden, die ihrerseits an das Energieverteilungsnetz angeschlossen sind. In manchen Fällen ist es notwendig, die Sendeanlage, die Tonfrequenz oder Hochfrequenz aussendet, an zwei verschiedene Netzteile oder Sammelschienen des Energieverteilungsnetzes anzukoppeln, wobei die Möglichkeit besteht, daß die beiden Netzteile oder Sammelschienen gelegentlich asynchron betrieben sind. Um zu gewährleisten daß der Impulsgeber in der Zentralstelle mit derselben Frequenz wie das ausgesteuerte Netz betrieben wird, hat man bisher zur Kommandoaussendung zwei Impulsgeber vorgesehen, wobei der Antriebsmotor des einen mit der Spannung des Sammelschienensystems z und der Antriebsmotor des anderen mit der Spannung des Sammelschienensystems 2 über Spannungswandler gespeist wurde. Der Aufwand. bei dieser Lösung ist relativ hoch, insbesondere dann, wenn die Schaltbefehle von' einer Kommandostelle aus mittels einer übergeordneten Fernsteuerung zunächst zu verschiedenen Unterwerken übertragen werden, von denen jedes eine auf zwei Sammelschienen arbeitende Sendeanlage enthält.Method for superimposing two possibly operated asynchronously Power supply units or busbars controlled by a rotating pulse generator Audio frequency pulses The electricity utilities are increasing strives to target certain consumer groups, such as street lamps, water tanks, etc., can be switched on and off from a central point by means of a remote control system. At this central point there is an audio frequency transmitter whose frequency is imposed on the network in pulses at the rate of the commands provided. As well as In most cases, synchronously rotating dialers are used in both the transmitter and the receivers, which work according to the start-stop principle and which ensure compliance with the necessary Synchronous operation are driven by synchronous motors, which in turn are connected to the power distribution network are connected. In some cases it is necessary to adjust the transmission system, the audio frequency or emits high frequency to two different power supplies or busbars of the power distribution network, with the possibility that the both power supplies or busbars are occasionally operated asynchronously. In order to ensure that the pulse generator in the central office with the same frequency as The controlled network is operated, so far one has to send two commands Pulse generator provided, the drive motor of the one with the voltage of the busbar system z and the drive motor of the other with the voltage of the busbar system 2 was fed via voltage converter. The effort. in this solution is relatively high, especially when the switching commands from 'a command post from a higher-level remote control initially to various substations are transmitted, each of which is a transmitter working on two busbars contains.

Die Erfindung betrifft ein Verfahren zur Überlagerung von zwei gegebenenfalls asynchron betriebenen, Netzteilen oder Sammelschienen mit von einem umlaufenden Impulsgeber gesteuerten Tonfrequenzimpulsen. Eine wesentliche Vereinfachung wird erfindungsgemäß dadurch erreicht, daß am Sendeort nur ein Impulsgeber vorhanden ist, der mit einer Umlaufgeschwindigkeit entsprechend dem arithmetischen Mittel der beiden Netzfrequenzen angetrieben wird. Zum Antrieb des Impulsgebers dienen zwei Synchronmotoren, von denen der eine an. das eine, der andere an das andere Netz angeschlossen ist und die auf ein Differentialgetriebe arbeiten. Von der Ausgangswelle des Differentialgetriebes Wird der Kontaktarm des Impulsgebers in Umlauf versetzt. Durch eine Anordnung dieser Art wird erreicht, daß der Fehler zwischen der Umlaufgeschwindigkeit des Impulsgebers und der Umlaufgeschwindigkeit der jeweiligen Netzempfänger auf die Hälfte des bisherigen Fehlers reduziert wird.The invention relates to a method for superimposing two optionally asynchronously operated, power supply units or busbars with a circulating Pulse generator controlled audio frequency pulses. A major simplification will be according to the invention achieved in that there is only one pulse generator at the transmission location is the one with a rotational speed corresponding to the arithmetic mean of the two mains frequencies is driven. Serve to drive the pulse generator two synchronous motors, one of which is on. one, the other to the other Network is connected and which work on a differential gear. From the output shaft of the differential gear The contact arm of the pulse generator is set in rotation. By an arrangement of this kind it is achieved that the error between the rotational speed of the pulse generator and the speed of rotation of the respective network receiver half of the previous error is reduced.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es sind zwei Sammelschienen i, 2 vorhanden, die voraussetzungsgemäß gegebenenfalls asynchron betrieben werden können und denen die von einem Generator 3 erzeugte Tonfrequenz aufgedrückt werden soll. Der Generator wird von einem Motor q. konstanter Drehzahl angetrieben. Für jede der beiden Sammelschienen i, 2 ist' eine besondere Ankopplung vorhanden, die in dem einen Fall aus dem Kondensator Cl, der Induktivität L1 und dem Transformator Trl besteht.. Bei der anderen Sammelschiene besteht die Ankopplung -aus dem Kondensator C2, der Induktivität L2 und dem Transformator Ty, Zur Überlagerung der Tonfrequenz sind diese beiden Ankopplungskreise über den Kontakt s eines Tastschützes S mit'dem Generator 3 verbunden. Das Ansprechen des Tastschützes S wird von dem umlaufenden Kontaktarm 5 eines Impulswählers gesteuert. Die einzelnen am Umfang des Impulswählers verteilten Kontakte werden durch nicht dargestellte Befehlsschalter 6 an Spannung gelegt. Beim Umlauf streicht der Kontaktarm über die einzelnen Kontakte hinweg und verbindet alle Kontakte KI, K2 ... K22, an denen mittels der Befehlsschalter 6 Spannung angelegt ist, in den durch die Umlaufgeschwindigkeit gegebenen Zeitabständen mit dem Tastschütz S. Auf diese Weise ist gewährleistet, daß die Tonfrequenz des Generators 3 impulsmäßig in den für ein bestimmtes Kommando vorgesehenen Zeitabständen den Ankopplungskreisen zugeführt wird.An exemplary embodiment of the invention is shown schematically in the drawing. There are two busbars i, 2 which, according to the requirements, can optionally be operated asynchronously and on which the audio frequency generated by a generator 3 is to be impressed. The generator is powered by a motor q. constant speed driven. For each of the two busbars i, 2 there is a special coupling, which in one case consists of the capacitor Cl, the inductance L1 and the transformer Trl. In the other busbar, the coupling consists of the capacitor C2, the inductance L2 and the transformer Ty, in order to superimpose the audio frequency, these two coupling circuits are connected to the generator 3 via the contact s of a contactor S. The response of the contactor S is controlled by the rotating contact arm 5 of a pulse selector. The individual contacts distributed around the circumference of the pulse selector are connected to voltage by command switch 6 (not shown). During rotation, the contact arm sweeps over the individual contacts and connects all contacts KI, K2 ... K22, to which voltage is applied by means of the command switch 6, with the contactor S at the time intervals given by the rotation speed. This ensures that that the audio frequency of the generator 3 is pulsed to the coupling circuits at the intervals provided for a specific command.

Zum Antrieb des Kontaktarms 5 dienen zwei Synchronmotoren Syl und Sy2, die wahlweise an eine der beiden Sammelschienen i, 2 angeschlossen werden können. In einem Differentialgetriebe 7 wird die mittlere Drehzahl gebildet, die zuni Antrieb des Kontaktarms 5 dient. Die Umlaufgeschwindigkeit des Kontaktarms entspricht somit in jedem Augenblick dem arithmetischen Mittel zwischen den- Frequenzen der beiden Sammelschienen i, z.Two synchronous motors Syl and serve to drive the contact arm 5 Sy2, which can optionally be connected to one of the two busbars i, 2. In a differential gear 7, the mean speed is formed, which is the initial drive of the contact arm 5 is used. The speed of rotation of the contact arm thus corresponds at each instant the arithmetic mean between the frequencies of the two Busbars i, e.g.

Um zu verhindern, daß bei Ausfall einer Sammelschienenspannung der Impulsgeber mit der halben Geschwindigkeit läuft, wird erfindungsgemäß # durch den beiden Spannungswandlern W1, WZ zugeordnete Spannungsrelais Spl, Spe dafür gesorgt, daß der Synchronmotor, der an .die gegebenenfalls spannungslos gewordene Sammelschiene angeschlossen ist, seine Spannung von der anderen, noch Spannung führenden Sammelschiene erhält.In order to prevent the Pulse generator runs at half the speed, according to the invention # by the voltage relays Spl, Spe assigned to both voltage converters W1, WZ ensure that the synchronous motor connected to the busbar that may have been de-energized is connected, its voltage from the other, still voltage-carrying busbar receives.

Das Differentialgetriebe 7 bildet, wie schon erwähnt, den arithmetischen Mittelwert der beidenDrehzahlen n1, n2, die den Netzfrequenzen entsprechen und überträgt ihn auf den Impulsgeber der Sendeänlage. Die ordnungsgemäße Funktion des Impulsgebers wird durch die Spannungsüberwachungsrelais Spl, Spe sichergestellt.As already mentioned, the differential gear 7 forms the arithmetic mean of the two speeds n1, n2, which correspond to the network frequencies and transmits it to the pulse generator of the transmission system. The correct functioning of the pulse generator is ensured by the voltage monitoring relays Spl, Spe.

Beim Betrieb der Anlage können folgende Fälle auftreten Stehen beide Sammelschienen i, 2 unter Spannung, so sind die Relais Spl und Spe erregt und legen ihre Kontakte spl und Spe in die mit a bezeichnete Stellung. Dann erhält der Synchronmotor Syl seine Spannung von der Sammelschiene i und der Motor Sy, seine Spannung von der Sammelschiene 2. Dieser Fall entspricht den Normalzustand.When operating the system, the following cases can occur: Both of them are standing Busbars i, 2 are energized, so the relays Spl and Spe are energized and open their contacts spl and Spe in the position marked a. Then the synchronous motor receives Syl its voltage from the busbar i and the motor Sy, its voltage from of busbar 2. This case corresponds to the normal state.

Ist bei einem weiteren Betriebsfall die Sammelschiene i ohne Spannung, dann ist auch das Relais Spl spannungslos und der zugehörige Umschaltkontakt spl befindet sich in der Stellung b. Beide Synchronmotoren sind dann an die noch Spannung führende Sammelschiene 2 angeschlossen.If the busbar i is de-energized in another operating case, then the relay Spl is also de-energized and the associated changeover contact spl is in position b. Both synchronous motors are then still connected to the voltage leading busbar 2 connected.

Ist in einem weiteren Fall die Sammelschiene 2 ohne Spannung, so ergibt sich durch Abfall des Relais Spe die andere Umschaltmöglichkeit, bei der beide Synchronmotoren an die -Sammelschiene i angeschlossen sind.If the busbar 2 is without voltage in a further case, the result is the other switchover option, in which both synchronous motors are connected to the busbar i.

Sind schließlich beide Sammelschienen ohne Spannung, so fallen naturgemäß beide Spannungsrelais ab und eine Überlagerung wird in diesem Fall, der eine Störung bedeutet, unmöglich, weil die Motoren nicht mehr umlaufen.If, after all, both busbars are without voltage, they naturally drop both voltage relays turn off and an overlay is created in this case, which is a malfunction means impossible because the motors no longer rotate.
