Description

Anordnung zur Fernsteuerung durch gleichzeitige Absenkung einer verketteten Spannung Im Hauptpatent 68o4:3o ist eine Anordnung zur Fernsteuerung durch gleichzeitige Absenkung einer verketteten Spannung an allen gekuppelten Speisepunkten eines Drehstromversorgungsgebietes ohne Zuhilfenahme besonderer Steuerleitungen angegeben. Hierbei ist in den Zug einer Phase einer beliebigen Kuppelleitung zwischen je zwei Speisepunkten des Versorgungsgebietes ein auf eine sehr kurze Unterbrechungsdauer eingestellter Hilfstastschalter eingefügt, welcher unmittelbar vom Sender her gesteuert wird. An den Endpunkten der Kuppelleitung, also in den gleichzeitig zu tastenden Speisepunkten sind hochempfindliche Empfangsrelais angeordnet, welche auf den Eingriff des Hilfstastschalters in die Kuppelleitung ansprechen und die in den Unterwerken angebrachten Haupttastschalter synchron auslösen. Um nun die im Netz verteilt angeordneten Relais,. die zur Kommandoausführung bestimmt sind, nicht schon durch diesen Vorimpuls zum Ansprechen zu bringen, ist im Hauptpatent vorgeschlagen worden, den bzw. die Hilfstastschalter in eine andere Phase zu legen, als sie zur Kommandoaussendung benutzt wird. Allerdings hat dies zur Folge, daß nunmehr zwei Phasen des vorhandenen Verteilungsnetzes getastet werden und daß außerdem der Aufwand an Schaltermaterial mitunter ziemlich groß wird, besonders dann, wenn es sich um ein ve-zweigtes Netz, etwa nach Abb. 2 des Hauptpatents, handelt.Arrangement for remote control by simultaneous lowering of a chained Voltage In the main patent 68o4: 3o is an arrangement for remote control by simultaneous Reduction of a linked voltage at all coupled feed points of a three-phase power supply area specified without the aid of special control lines. Here is one in the train Phase of any coupling line between two feed points in the supply area an auxiliary push button switch set for a very short interruption period is inserted, which is controlled directly from the transmitter. At the end points of the coupling line, so there are highly sensitive receiving relays in the feed points that are to be sampled at the same time arranged, which on the intervention of the auxiliary switch in the coupling line respond and trigger the main pushbutton switches installed in the substations synchronously. In order to now distribute the relays in the network. which is intended for the execution of the command are not to be made to respond by this preliminary impulse, is in the main patent it has been proposed to put the auxiliary pushbutton switch (s) in a different phase, when it is used to send commands. However, this has the consequence that now two phases of the existing distribution network are keyed and that also the cost of switch material is sometimes quite large, especially when it is a branched network, as shown in Fig. 2 of the main patent.

Die Anordnung wird erfindungsgemäß dadurch wesentlich vereinfacht, daß der Haupttastschalter selbst zur Abgabe des oder der Vorim_ pulse dient. Ein Ausführungsbeispiel der Erfindung ist schematisch in der Abbildung dargestellt. Darin sind mit Gi, Gg, G3 Drehstroms. generatoren bzw. Drehstromkraftwerke bezeiel.vnet, die durch Leitungen miteinander gekupgrIJ't: sind und parallel arbeiten. Die von jeder Strom-.` quelle gespeisten Verbraucher sind der besseren Übersicht halber nicht eingezeichnet. Es ist aber so, daß eine Betätigung des Tastschalters an der Hauptstelle zwar eine Spannungsabsenkung auch in der Nähe der Stromquellen G2 und G3 hervorruft, daß diese aber mit den üblichen Empfangsrelais nicht ohne weiteres aufgenommen werden kann. Es ist deshalb außer dem Tastschalter TSl an der Stromquelle G1, die weiterhin als Hauptstelle bezeichnet wird, noch an jeder Unterstelle ein Tastschalter TS2 bzw. TS, angeordnet. Alle diese Tastschalter liegen in der gleichen Phase, an die auch die nicht dargestellten, die Aufnahme und Ausführung des Kommandos bewirkenden Empfangsrelais angeschlossen sind.According to the invention, the arrangement is significantly simplified by that the main pushbutton itself is used to deliver the Vorim_ pulse serves. An embodiment of the invention is shown schematically in the figure. There are three-phase current with Gi, Gg, G3. generators or three-phase power plants bezeiel.vnet, which are connected to one another by lines and work in parallel. The from consumers fed by each electricity source are for the sake of clarity not shown. But it is so that an operation of the pushbutton switch on the Mainly a voltage drop also in the vicinity of the current sources G2 and G3 causes this, however, to not readily work with the usual receiving relays can be included. It is therefore in addition to the push button switch TSl on the power source G1, which is still referred to as the main unit, is still entered at each sub-unit Push button switch TS2 or TS, arranged. All of these pushbutton switches are in the same place Phase, which also includes those not shown, the inclusion and execution of the command effecting receiving relays are connected.

Um nun eine synchrone Betätigung aller Tastschalter und damit eine gleichmäßige Kommandoausbreitung im Netz zu gewährleisten, sind folgende Maßnahmen getroffen: Der Tastschalter TS, ist durch einen Widerstand W und einen Trennschalter Ty überbrückt. Es wird vor jeder eigentlichen' Hauptimpulsgabe ein Vorimpuls gesandt, der aus einer Spannungsabsenkung besteht, die durch kurzzeitige Öffnung des Tastschalters TSi hervorgerufen wird. Dabei ist dieser Schalter durch den Widerstand W und den Trennschalter Ty überbrückt, so daß mit Rücksicht darauf, entsprechend den jeweiligen Belastungsverhältnissen, die Spannung dieser Phase mehr oder weniger aufrechterhalten und zu einem geringeren Betrag abgesenkt wird als bei der darauffolgenden eigentlichen Hauptimpulsgabe. Die Bemessung des. Widerstandes W ist so getroffen, daß auch bei Berücksichtigung der jeweiligen Belastung dieser Phase eine Spannungsabsenkung zustande kommt, die ausreicht, um die besonders empfindlichen Empfangsrelais R2 und R3 in den Unterwerken zum Ansprechen zu bringen. Diese Relais nehmen also den Vorimpuls auf und. bringen über örtliche Stromkreise die zugehörigen Tastschalter TS2 bzw. TS, nach einer festliegenden Zeit zum Ansprechen. Diese Verzögerung ist durch die Eigenzeit der Relais sowie der Tastschalter bedingt und liegt ein für allemal fest. Die Ausbreitung des Vorimpulses im Netz erfolgt mit Lichtgeschwindigkeit.In order to now enable synchronous actuation of all pushbuttons and thus a The following measures must be taken to ensure uniform command propagation in the network hit: the push button switch TS, is through a resistor W and a circuit breaker Ty bridged. A pre-impulse is sent before each actual main impulse, which consists of a voltage drop caused by briefly opening the pushbutton switch TSi is caused. This switch is through the resistor W and the Circuit breaker Ty bridged, so that with consideration, according to the respective Load conditions that more or less maintain the tension of this phase and is lowered to a lesser extent than the subsequent actual Main impetus. The dimensioning of the. Resistance W is made so that also with Taking into account the respective load of this phase, a voltage drop is achieved that is sufficient to keep the particularly sensitive receiving relays R2 and R3 in to make the substations respond. So these relays take the pre-pulse on and. bring the associated pushbutton switches TS2 resp. TS, after a fixed time to respond. This delay is due to the The proper time of the relays and the pushbutton switches is determined and is fixed once and for all. The pre-impulse propagates in the network at the speed of light.

Durch den Vorimpuls wird zweckmäßig auch auf den Trennschalter Ty eingewirkt und dieser geöffnet, so daß der Tastschalter TS, bei dem nun folgenden Hauptimpuls allein die Stromführung der getasteten Phase übernimmt. Im gleichen Zeitpunkt, in dem über die Empfangsrelais R2 und R3 an den Unterstellen G2 und G3 die Betätigung der Tastschalter TS, und IS, erfolgt, wird nun auch der Tastschalter TS, _der Hauptstelle geöffnet. Das einfachste Mitte,. um diesen Vorgang von dem vorausgegangenen Vorimpuls abhängig zu machen, ist edle im Hauptpatent vorgeschlagene Anordnung eines gleichartigen in der Hauptstelle selbst. Schließlich sind Mittel vorgesehen, die nach abgegebenem Hauptimpuls, d. h. nach Schließung des Tastschalters TSl, wieder eine selbsttätige Schließung des Trennschalters Tr bewirken.The pre-pulse expediently also affects the circuit breaker Ty acted and this opened, so that the push button switch TS, in the case of the now following Main pulse alone takes over the current flow of the gated phase. In the same Time at which the receiving relays R2 and R3 at the sub-stations G2 and G3 If the pushbutton switches TS and IS are operated, the pushbutton switch is now also TS, _the main office open. The simplest middle. to remove this process from the Making the preceding pre-impulse dependent is noble proposed in the main patent Arrangement of a similar in the main body itself. Finally, are means provided that after the main pulse has been emitted, d. H. after closing the pushbutton switch TSl, cause the disconnector Tr to close automatically again.

Es wird daher mit einem Mindestaufwand an Schaltern eine gleichmäßige Ausbreitung der Spannungsabsenkungen im Netz und damit ein sicheres Ansprechen aller Empfangs_elais gewährleistet. Außerdem hat die Überbrückung des Tastschalters TS, die Wirkung, daß dieser im Normalfall nur einen Teil des Stroms dieser Phase führt und somit schwächer dimensioniert werden kann..It is therefore a uniform with a minimum number of switches Spread of the voltage drops in the network and thus a safe response to everyone Receive_relay guaranteed. In addition, the bridging of the push button switch TS, the effect that it normally only carries part of the current in this phase and thus can be dimensioned weaker ..

An der Hauptstelle sind die üblichen Verriegelungsschaltungen vorzusehen, die eine Aussendung des Vorimpulses durch den Tastschalter TS, nur gestatten, wenn der Trennschalter Tr eingelegt ist. Schließlich werden Zweckmäßig in der Hauptstelle auch Anzeigevorrichtungen vorgesehen, welche die jeweilige Stellung der Schalter TSl und Ty anzeigen und die Zulässigkeit der Aussendung der Vorimpulse bzw. des eigentlichen Kommandos erkennen lassen.The usual interlocking circuits are to be provided at the main unit, which allow the pre-pulse to be transmitted by the push-button switch TS, only if the isolating switch Tr is inserted. Finally, it will be expedient in the main office display devices are also provided which show the respective position of the switch TSl and Ty show and the permissibility of the transmission of the pre-pulses or the let the actual commands be recognized.

Für die Betätigung aller Tastschalter ist zweckmäßig eine Druckknopfsteuerung vorgesehen, die, je nachdem, welcher Druckknopf betätigt wird, selbsttätig die Aussendung der entsprechenden Vorimpulsfolge bzw. Kommandoimpulsfolge vornimmt.A push-button control is useful for actuating all push-button switches provided, which, depending on which push button is pressed, the transmission automatically the corresponding pre-pulse sequence or command pulse sequence.
