Description

Einrichtung zur Fernbedienung einer Mehrzahl von Schaltgeräten eines Drehstromnetzes Es sind Fernbedienungseinrichtungen bekanntgeworden, bei denen durch Beeinflussung des Netzes, in dem die zu steuernden Geräte angebracht sind, Schaltbefehle gegeben werden. Bei diesen bekannten Einrichtungen arbeitet man in der Weise, daB man entweder die Spannung des Netzes kurzzeitig erhöht oder indem man das Netz kurzzeitig abschaltet oder indem man den Netzströmen Ströme fremder Frequenz. überlagert. Bei dem letzteren Verfahren hat man zur Kommandogabe stets besondere Stromerzeuger für die netzfremden Frequenzen notwendig, die die Anlage wesentlich verteuern. Die Benutzung von Spannungserhöhungen und die Abschaltung des Netzes zur Übertragung von Schaltbefehlen schafft keine eindeutigen Kriterien für die Übertragung eines Schaltbefehls, da während des Netzbetriebes sowohl Abschaltungen als auch Spannungserhöhungen unabhängig von der Kommandogabe auftreten können. Es sind deshalb bei diesen Anordnungen besondere Vorkehrungen, z: B. Abgabe von mehreren Zeichen in festgelegtem zeitlichem Abstand, zu treffen, um die notwendige Sicherheit bei der Kommandogabe zu erzielen.Device for remote control of a plurality of switching devices Three-phase network There are remote control devices are known in which by Influencing the network in which the devices to be controlled are installed, switching commands are given. In these known devices one works in such a way that either the voltage of the network is increased for a short time or by the network for a short time switches off or by adding currents of foreign frequencies to the mains. superimposed. at The latter method always has special power generators for giving commands the non-network frequencies are necessary, which make the system considerably more expensive. The usage of voltage increases and the disconnection of the network for the transmission of switching commands creates no clear criteria for the transmission of a switching command, because both shutdowns and voltage increases independently during mains operation from the command. There are therefore special features in these arrangements Precautions, e.g. submission of several characters at a specified time interval, to be met in order to achieve the necessary security when giving commands.

Die Erfindung zeigt eine Einrichtung zur Fernbedienung einer Mehrzahl von Schaltgeräten über drehstromgespeiste Leitungen, an die keine Drehstrommotoren angeschlossen sind, bei der die Schaltbefehle ohne kostspielige Hilfseinrichtungen, %t-ie z. B. Frequenzerzeuger für Überlagerungsfrequznzen oder durch Benutzung von Kriterien, die im normalen .Betrieb des Netzes auftreten können, übertragen werden. Gemäß der Erlindung werden die Schaltbefehle durch die Vertauschung von zwei Phasen der Drehstromleitungen gegeben.The invention shows a device for remote control of a plurality of switching devices via three-phase-fed lines to which no three-phase motors are connected, in which the switching commands without expensive auxiliary equipment, % t-ie z. B. Frequency generator for superimposition frequencies or by using Criteria that can occur in normal operation of the network transfer will. According to the invention, the switching commands are obtained by interchanging given two phases of the three-phase power lines.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung in ihrer Anwendung auf die Fernschaltung von Alarmsirenen. Hierbei erfolgt die Steuerung der Alarmsirenen über drehstromgespeiste Leitungen, die Straßenbeleuchtungsnetzen zugeordnet sind. Diesem Ausführungsbeispiel der Erfindung kommt besondere- Bedeutung zti, denn sie zeigt eine einfache Fernsteuereinrichtung für Alarmsirenen, die zum Zwecke des Luftschutzes in vielen Stellen eines Stadtbezirkes aufgestellt werden. Für Fliegeralarmsirenen ist die Fernsteuerung besonders schwierig, da die Sirenen oft -weit voneinander entfernt liegen und die Betätigung über besondere Steuerleitungen kostspielig ist, vor allen Dingen deshalb, weil die Sirenen nur in verhältnismäßig seltenen Fällen betätigt werden und die gesamten Fernsteuerleitungenwährend des größten Teiles der Zeit unbenutzt bleiben. Die Benutzung des Straßenlampennetzes gibt hierbei für die Steuerung der Alarmsirenen eine günstige -Möglichkeit. Die Speiseleitungen der Straßenlampen führen nämlich durch fast sämtliche Straßenzüge des betroffenen Ortes, und man ist infolgedessen in keiner Weise gebunden, die Alarmsirenen an einem besonderen Punkt aufzustellen. Die zu den Sirenen führenden Leitungen können als kurze Stichleitungen ausgeführt werden. Die Umschaltung der Phasen eines drehstromgespeisten Straßenlampennetzes bietet insofern keine Schwierigkeiten, als in derartigen Netzen keine Drehstrommotoren als Verbraucher angeordnet sind, sondern nur solche Verbraucher, für die der Umlauf des Drehfeldes gleichgültig ist.The figure shows an embodiment of the invention in their Application to remote switching of alarm sirens. The control takes place here the alarm sirens via three-phase current-fed lines, the street lighting networks assigned. This embodiment of the invention is of particular importance zti, because it shows a simple remote control device for alarm sirens that are used for Air protection purposes are set up in many places in a city district. Remote control is particularly difficult for air raid sirens because the sirens are often far apart and are operated via special control lines is expensive, especially because the sirens are only in proportion operated in rare cases and all remote control lines during the remain unused for most of the time. Use of the street lamp network is an inexpensive option for controlling the alarm sirens. the This is because the feed lines for the street lamps run through almost all streets of the affected place, and as a result one is in no way bound to the alarm sirens to be set up at a special point. The lines leading to the sirens can be designed as short stub lines. Switching the phases of a three-phase current-fed Street lamp network offers no difficulties in so far as in such networks no three-phase motors are arranged as consumers, but only those consumers for which the rotation of the rotating field is indifferent.

In der Abbildung ist mit i das Hochspaililungsdrehstromnetz bezeichnet, das den Strom zur Speisung der Straßenlampen über den Transformator 3 liefert. Die Einschaltung des Transformators erfolgt dabei über den Schalter z. Bei Einlegen dieses Schalters kommen sämtliche Straßenlampen zum Aufleuchten. Von dem Transformator aus führen die Leitungen zu dem Sammelschienensysteni i i, von dem die einzelnen Speiseleitungen abgehen. Zwischen dem Transformator 3 und dem Saminelschienensystem i i ist noch in den Leitungen 6 und ; ein Umschalter 5 angebracht, der zur Vertauschung der Phasen des Drehstromnetzes dient. In den voll dein Sammelschienensystem i i ausgehenden Leitungen liegen die Lampen 8 und auch die Relais 9. Die Relais kommen zum Ansprechen, wenn das Drehfeld des Netzes umgekehrt wird, d. h. wenn zwei Phasen des Dreh-Feldes vertauscht werden. In Abhängigkeit von diesen Relais werden die Stromkreise der Alarmsirenen io geschlossen. Die Speisung der Sirenen kann dabei aus dem Hauptnetz erfolgen.In the figure, i denotes the high-speed three-phase network, which supplies the electricity to feed the street lamps via the transformer 3. the The transformer is switched on using the switch z. When inserting this switch all street lights come on. From the transformer from lead the lines to the busbar system i i, from which the individual Feed lines come off. Between the transformer 3 and the Saminel rail system i i is still on lines 6 and; a changeover switch 5 is attached, for interchanging the phases of the three-phase network. In the fully your busbar system i i outgoing lines are the lamps 8 and also the relays 9. The relays come to respond when the rotating field of the network is reversed, d. H. if two phases of the spin field can be swapped. Depending on these relays, the Alarm siren circuits closed. The sirens can be fed from the main network.

Die Wirkungsweise der Schaltung ist fol.-gendermaßen: Es sei zunächst angenommen, daß der Schalter 2 geöffnet sei. Wird der Schalter 2 eingelegt, so erhalten über den Transformator das Sammelschienensysteni i i und die an die Abzweigleitungen angeschlossenen Lampen 8 Spannung. Auch die Relais 9, welche die Alarmsirenen io steuern, erhalten Spannung. Diese Relais sind jedoch so ausgebildet, daß die von ihnen gesteuerten Kontakte nicht geschlossen werden, wenn der sie speisende Drehstrom einen normalen Feldumlaufsinn besitzt. Soll mit den Sirenen Alarm gegeben werden, so wird dies dadurch erreicht, daß man den Umschalter 5 in die andere Lage bewegt und damit die Phasen 6 und 7 des Drehstromnetzes vertauscht. Solange diese Phasenvertauschung aufrechterhalten wird, bleiben die Relais 9 im angesprochenen Zustand und halten die Alarmsirenen io eingeschaltet.The mode of operation of the circuit is as follows: Let it be first assume that switch 2 is open. If the switch 2 is inserted, so obtained via the transformer to the busbar system i i and to the branch lines connected lamps 8 voltage. Also the relays 9, which the alarm sirens io control, get tension. However, these relays are designed so that the Contacts controlled by them are not closed when the three-phase current feeding them has a normal sense of field circulation. Should an alarm be given with the sirens, so this is achieved by moving the switch 5 to the other position and thus phases 6 and 7 of the three-phase network interchanged. As long as this phase reversal is maintained, the relays 9 remain in the addressed state and hold the alarm sirens switched on.

Erfolgt die Speisung der Straßenlampen und der Alarmsirenen aus einem Hauptnetz, an das auch andere Verbraucher angeschlossen sind, so kann man die Ein- und Ausschaltung der Straßenlampen und Sirenen in bekannter Weise über besondere Drehstromsteuerleitungen vornehmen. In diesem Falle werden für die Schaltung der Straßenlampen nicht die Speiseleitungen benutzt, sondern Steuerleitungen benötigt.The street lights and the alarm sirens are fed from one Main network, to which other consumers are also connected, so you can and turning off street lights and sirens in a known manner via special Make three-phase control lines. In this case, the Street lamps do not use the feed lines, but rather control lines.

Zur Betätigung der Alarmsirenen schaltet man in diesem Falle in die Steuerleitungen einen Phasenumschalter, der es gestattet, den Umlaufsinn des Drehfeldes auf den Steuerleitungen umzukehren. Die zur Schaltung der Sirenen verwendeten Relais können derart ausgebildet werden, daß sie auch dann noch auf eine Umkehrung des Drehfeldes ansprechen, wenn die auf den Steuerleitungen vorhandene Spannung nur einen kleinen Teil der Normalspannung beträgt. Man ist daim für die Schaltung der Straßenlampen nicht all eine bestimmte Steuerspannung gebunden.In this case, switch to the to activate the alarm sirens Control lines have a phase switch that allows the direction of rotation of the rotating field reverse on the control lines. The relays used to switch the sirens can be designed in such a way that they also respond to a reversal of the Responding to the rotating field if the voltage present on the control lines is only is a small part of the normal stress. One is there for the switching of the Street lights are not all tied to a specific control voltage.

:Ulan kann auch von der Phasenumschaltuiig des Drehstromnetzes zu Fernsteuerzwecken in der Weise Gebrauch machen, daß man die Phasenumkehrung nur kurzzeitig aufrechterhält und in Abhängigkeit von der Dauer der Phasenumkehrung verschieden'-Schaltungen vornimmt.: Ulan can also from the phase switching of the three-phase network to Make use of remote control purposes in such a way that you can only reverse the phase sustains briefly and depending on the duration of the phase reversal different 'circuits.
