Description

Schaltungsanordnung- zur Aussendung von Fernsteuerbefehlen mittels kurzzeitiger Spannungsunterbrechung Es ist bekannt, bei der Fernsteuerung mittels mehrfacher kurzzeitiger Unterbrechung der Netzspannung zur Einsparung von Tastschaltern das Prinzip der vierten Schiene ,anzuwenden. Dieses Prinzip besteht . darin, daß neben dem vorhandenen Sammelschlenensystem eine besondere vierte Schiene .angeoTdnet wird, an die die entsprechenden Phasenleiter .aller derjenigen abgehenden Leitungen angeschlossen werden, die Fernsteuerbefehle erhalten sollen. Die vierte Schiene wird mit der gleichphasigen Sammelschiene über den Tastschalter verbunden. Dabei ist zu beachten, daß die Anordnung einer vierten Sammelschiene Schwierigkeiten dann ergibt, wenn in. der Schaltanlage nicht genügend Platz vorhanden ist, um diese vierte Schiene, die gegen Erde genau so wie jede andere Sammelschiene isoliert sein muß, unterzübringen. - Aus diesem Grunde ist im Hauptpatent 7o8 322 vorgeschlagen, daß die mit F.ernsteuerbefehlen zu versehenden Phasenleiter durch zwei pärallele Leitungen miteinander verbunden sind, zwischen welche der Tastschälter geschaltet ist. Durch den Anschluß der beiden parallelen Leitungen ergeben sich an jedem zu tastenden Phasenleiter zwei Anschlüßstellen, und zwischen diese beiden Anschlußstellen ist ein die Aussendung der Fernsteuerbefehleermöglichender Hilfsschalter geschaltet. Ferner ist in die Parallelverbindung zwischen jedem zu tastenden Phasenleiter und dem Tastschalter ein doppelpoliger Trennschaltereingebaut: Diese Anordnung ist in o Fig. i bzw. 2 schematisch dargestellt.Circuit arrangement for sending remote control commands by means of Brief voltage interruption It is known to use remote control Multiple brief interruptions in the mains voltage to save push-button switches the principle of the fourth rail to apply. This principle exists. in that In addition to the existing collective loop system, there is a special fourth line called .angeoTdnet to which the corresponding phase conductors .aller of those outgoing lines that are to receive remote control commands. The fourth rail is connected to the in-phase busbar via the push button switch. Included It should be noted that the arrangement of a fourth busbar difficulties then results when there is not enough space in the switchgear to accommodate this fourth Rail, which must be insulated from earth just like any other busbar, accommodate. - For this reason it is proposed in the main patent 7o8 322 that the phase conductors to be provided with remote control commands through two parallel lines are connected to each other, between which the push button switch is connected. By the connection of the two parallel lines result at each to be groped Phase conductor two connection points, and between these two connection points is an auxiliary switch enabling the transmission of remote control commands is switched. Furthermore, in the parallel connection between each phase conductor to be scanned and A double-pole disconnector is built into the pushbutton switch: This arrangement is shown in o Fig. i and 2 shown schematically.

In Fig. i sind mit R, S, T die Sammelschienen eines Drehstromsystems bezeichnet, an das zwei Abzweigleitungen ,angeschlossen sind. In jeder Abzweigleitung liegt :ein dreipoliger Leistungsschalter i bzw. 2. Es ist angenommen, d.aß die Phasenleiter F2 der'; Abzweigleitungen Fernsteuerbefehle erhalt,#f sollen. Zu diesem Zwecke sind diese beiden:' Phasenleiter untereinander durch zwei parallele Leitungen 8, 9 verbunden, zwischen die der Tastschalter 3 geschaltet ist. In den beiden parallelen Leitungen liegt auf jeder Seite des Tastschalters ein doppelpoliger Trennschalter 6 bzw. 7. Zwischen den Ans,chlußstellen der beiden parallelen Leitungen an je einem Phasenleiter liegt ein Trennschalter q. bzw. 5. Wird beispielsweise der Trennschalter,l geöffnet, so ist der Phasenleiter F2 des linken Abzweiges über den Tastschalter 3 verbunden, und bei Betätigung des Tastschalters .erhält dieser Abzweig die gewünschten Spannungsabsenku@ngsimpulse. Ist voraussetzungsgemäß zur gleichen Zeit der Trennschalter 5 geschlossen, so wird der Phasenleiter R dieses Abzweiges durch die Tastschalterbetätigung nicht berührt.In Fig. I, R, S, T denote the busbars of a three-phase system to which two branch lines are connected. In each branch line there is: a three-pole circuit breaker i or 2. It is assumed that the phase conductors F2 of the '; Branch lines receive remote control commands, # f should. For this purpose, these two: 'Phase conductors are connected to one another by two parallel lines 8, 9, between which the pushbutton switch 3 is connected. A double-pole isolating switch 6 or 7 is located in the two parallel lines on each side of the pushbutton switch. A isolating switch q is located between the connection points of the two parallel lines on each phase conductor. or 5. If, for example, the isolating switch 1 is opened, the phase conductor F2 of the left branch is connected via the pushbutton switch 3, and when the pushbutton switch is actuated, this branch receives the desired voltage drop pulses. If the disconnector 5 is closed at the same time as required, the phase conductor R of this branch is not touched by the pushbutton actuation.

Ein weiteres Ausführungsbeispiel ist in Fig. 2 ,dargestellt. Darin sind mit R, S, T@ wiederum die Sammelschienen bezeichnet, von denen drei Drehstromleitungen abzweigen. In jedem Abzweig befindet sich ein Leistungsschalter i o bzw. i i bzw. 12. Außerdem ist in dem Phasenleiter R jedes Abzweiges ein einpoliger Trennschalter 19, 20, 21 vorhanden. Die beiden Anschlußstellen jedes dieser Trennschalter sind über doppelpolige Schalter 13, 1q., 15 mit den schon obenerwähnten parallelen Leitungen 18 verbunden. Zwischen diese beiden Leitungen ist der Tastschalter 16 geschaltet, und zwar unter Verwendung eines doppelpoligen Trennschalters 17. je nach der Stellung der ,einpoligen Trennschalter i g, 20,21 erhält der Phasenleiter R des betreffenden Abzweiges Fernsteuerbefehle, wenn der Tastschalter 16 betätigt und im übrigen die Schalter 13, 1.1, 15 und 17 geschlossen sind. Diese Schalter sind im übrigen notwendig, um, den Tasts.chalter 16 ,auf alle Fälle spannungslos zu machen, wenn Reparaturarbeiten o. dgl. vorgenommen werden sollen.Another embodiment is shown in FIG. In this R, S, T @ in turn denote the busbars, three of which are three-phase lines branch off. In each branch there is a circuit breaker i o or i i or 12. In addition, in the phase conductor R each branch is a single-pole disconnector 19, 20, 21 available. The two connection points of each of these circuit breakers are via double-pole switches 13, 1q., 15 with the parallel lines already mentioned above 18 connected. The pushbutton switch 16 is connected between these two lines, using a double-pole disconnector 17. depending on the position the, single-pole disconnector i g, 20,21 receives the phase conductor R of the relevant Branch remote control commands when the push button switch 16 is operated and the rest of the Switches 13, 1.1, 15 and 17 are closed. These switches are also necessary in order to de-energize the Tasts.chalter 16 in any case during repair work o. The like. To be made.

Aus diesen Darlegungen ist aber bereits ersichtlich, daß eine größere Anzahl von Schaltern betätigt werden muß, je nachdem, ob die eine oder andere Abzweigleitung von der Impulssendung ausgeschlossen sein soll, und das gleiche gilt, wenn gelegentlich Reparaturarbeiten an irgendeinem Schalter vorzunehmen sind.From these explanations it is already evident that a larger Number of switches must be operated, depending on whether one or the other branch line should be excluded from the impulse transmission, and the same applies if occasionally Repair work to be carried out on any switch.

Um hierbei die Gewißheit zu haben, daß stets die richtigen Schalter geschlossen bzw. geöffnet werden, ist die Anordnung gemäß der Erfindung so getroffen, daß die im Zuge . der zu tastenden Leiter liegenden einpoligen halter mit den zu dem gemeinsamen Tasti alter führenden zweipoligen Trennmessern `,j:' unter sich so verriegelt sind, daß die einpoligen Trennmesser nur dann geöffnet werdenkönnen, wenn die zweipoligen geschlossen sind und daß die einpoligen selbsttätig schließen, wenn die zweipoligen für sich oder gemeinsam mit den Leistungsschaltern geöffnet werden. Eine Verriegelung ist also beispielsweise zwischen den Trennschaltern .I und 5 und den zweipoligen Trennschaltern 6, in Abb. i vorgesehen. Es kann der Schalter 4. nur geöffnet werden, wenn der zugehörige zweipolige Schalter 6 geschlossen ist. Ebensa ist dafür gesorgt, daß der einpolige Schalter .1 sofort dann selbsttätig geschlossen wird, wenn der zugehörige Schalter 6 für sich allein oder gemeinsam mit dem Leistungsschalter r geöffnet wird. Die gleichen Anweisungen gelten für den einpoligen Schalter 5 bzw. den doppelpoligen Schalter 7 des ,anderen Abzweiges. Entsprechende Verriegelungen sind auch im Falle einer Schaltung nach Fig. 1-orzuxhen, und zwar sind hier die einpoligen Schalter -19,20,21 mit den doppelpoligen zugehörigen Schaltern 13, 14., 15 in der angegebenen Weise zu verriegeln. Auf diese Weise wird eine Gewähr' dafür erhalten, daß stets die züisammengehörigen Schalter in der richtigen Weise betätigt werden, um eine einwandfreie Kommandoaussendung zu gewährleisten bzw. um bestimmte Teile spannungslos zu machen.In order to have the certainty that the correct switches are always available are closed or opened, the arrangement according to the invention is such that that the train. of the conductor to be felt, single-pole holder with the to the common tasti of old leading bipolar disconnecting knives `, j: 'among themselves are locked in such a way that the single-pole disconnecting knives can only be opened when the two-pole are closed and that the single-pole close automatically, when the two-pole open for themselves or together with the circuit breakers will. A lock is for example between the disconnectors .I and 5 and the two-pole disconnectors 6, provided in Fig. i. It can be the switch 4. Can only be opened when the associated two-pole switch 6 is closed. It is also ensured that the single-pole switch .1 immediately then automatically is closed when the associated switch 6 alone or together is opened with the circuit breaker r. The same instructions apply to the single-pole switch 5 or the double-pole switch 7 of the other branch. Corresponding interlocks are also to be used in the case of a circuit according to FIG. 1, namely here are the single-pole switches -19,20,21 with the double-pole associated To lock switches 13, 14, 15 in the specified manner. That way will a guarantee that the switches that belong together are always in the correct position Way to be operated in order to ensure a proper command transmission or to de-energize certain parts.
