Description

Schaltungsanordnung zum gleichzeitigen Anlegen mehrerer Verbraucher an ein speisendes Netz Circuit arrangement for the simultaneous application of several consumers to a supply network
Die Erfindung betrifft eine Schaltungsanordnung zum gleichzeitigen An legen mehrerer elektrischer Verbraucher an ein speisendes Netz durch indirekte Betätigung eines Schalters.The invention relates to a circuit arrangement for simultaneously placing several electrical consumers on a supply network by indirect actuation of a switch.
Es ist bekannt, eine Vielzahl von Verbrauchern mittels einer Steckdosenleiste an das speisende Netz anzuschließen . DieseIt is known to connect a large number of consumers to the supply network by means of a power strip. This
Leiste kann einen auf alle Steckdosen gemeinsam wirkenden Schalter aufweisen , bei dessen Betätigung alle angeschlossenen Verbraucher gemeinsam an- oder abgeschaltet werden .The strip can have a switch which acts jointly on all sockets, when it is actuated all connected consumers are switched on or off together.
Dabei können hohe Einschaltstromstöße entstehen, die zu elektromagnetischen Störungen bei den miteinander verschalteten Verbrauchern führen können .This can result in high inrush currents, which can lead to electromagnetic interference in the interconnected consumers.
Es ist ein Nachteil dieser Leisten , daß sie wegen des an ihnen angebrachten und zu bedienenden Schalters zugänglich gehalten, also zum Beispiel auf dem Arbeitstisch gelagert werden müssen, wobei die Anschlußkabel der angeschlossenen Verbraucher ebenfalls auf den Tisch zu liegen kommen , was vielfach die Freiheit auf der Arbeitsfläche und deren Reinigung stört.It is a disadvantage of these strips that they are kept accessible due to the switch that is attached and operated on them, So, for example, must be stored on the work table, with the connecting cables of the connected consumers also lying on the table, which often disturbs freedom on the work surface and its cleaning.
Es ist auch bekannt, einen Verbraucher selbst mit einer entsprechenden Anzahl Anschluß-Steckdosen für andere Verbraucher zu versehen und diese direkt mit dem Schalter dieses Verbrauchers an- bzw . abzuschalten .It is also known to provide a consumer with a corresponding number of connecting sockets for other consumers and to switch this consumer directly on or off with the switch. switch off.
Damit ist die Hauptschaltstelle fest vorgegeben . Da eine solche Ausstattung der als Verbraucher vorgesehenen Geräte nicht serienmäßig ist, kann die zentrale Schaltfunktion nicht einem anderen Gerat zugewiesen werden, dessen Schalter für die Bedienperson besser zugänglich ist. Wenn die zusätzlichen Anschlußdosen zur Arbeitsfläche weisen, gilt das bezüglich Arbeitsfläche und Reinhaltung vorher Gesagte ebenfalls .This means that the main control point is fixed. Since such equipment of the devices provided as consumers is not standard, the central switching function cannot be assigned to another device whose switch is more accessible to the operator. If the additional junction boxes point towards the work surface, what has been said about work surface and cleanliness also applies.
Eine Schaltungsanordnung der eingangs genannten Art ist aus DE-OS 23 47 508 bekannt. Auf das speisende Netz wird mit Hilfe eines Kondensators eine Überspannung gegeben . Durch Betätigung eines Schalters wird der Kondensator kurzgeschlossen . Sein Entladestrom steuert ein Relais, durch das die Verbraucher angeschaltet werden .A circuit arrangement of the type mentioned is known from DE-OS 23 47 508. An overvoltage is applied to the supply network using a capacitor. The capacitor is short-circuited by actuating a switch. Its discharge current is controlled by a relay that switches on the consumers.
Aus der DE-OS 15 15 613 ist eine Schaltungsariordnung bekannt, bei der auf die speisende Netzieitung trägerfrequent modulierte Steuersignale gegeben werden , die einen elektronischen Schalter auslösen und damit die Verbraucher an das Netz legen. Durch besondere Frequenzfilter wird erreicht, daß die Steuersigna le nicht auf das Verbrauchernetz gelangen .From DE-OS 15 15 613 a circuit arrangement is known, in which carrier signals are given carrier frequency modulated control signals which trigger an electronic switch and thus connect the consumers to the network. Special frequency filters ensure that the control signals do not reach the consumer network.
Eine weitere Schaltungsanorduπg ist aus der DE-OS 27 38 434 bekannt . Ein am speisenden Netz liegendes Relais wird durch Betätigung eines Tasters ausgelöst und schaltet damit die Ver braucher ebenfalls an das Netz .Another circuit arrangement is known from DE-OS 27 38 434. A relay on the supply network is triggered by pressing a button and switches the ver need also to the network.
A llen zuletzt genannten Schaltungsanordnungen ist gemeinsam, daß sie ortsfeste I nstallationsmaßnahmen erfordern . Es ist nicht möglich , an einer beliebigen Zugangsstelle zum speisenden Netz eine beliebige An zahl von Verbrauchern anzuschließen und mit Hilfe eines zentral zu betätigenden Schalters anzuschalten .A ll the last-mentioned circuit arrangements have in common that they require fixed installation measures. It is not possible to connect any number of consumers to any access point to the supply network and to switch it on with the help of a centrally operated switch.
Der Erfindung lag daher die Aufgabe zugrunde, eine Schaltungsanordnung an zugeben , mit der die Verbraucher an den nächsten allgemein verfügbaren Zugang zum speisenden Netz angeschlossen werden können , bei der neben efnem am Verbraucher vorhandenen Schalter keine weiteren manuell zu betätigenden Schalter benötigt werden und bei der die zentrale Anschlußstelle für die Vielzahl der Verbraucher an beliebiger Stelle außerhalb der den Verbrauchern zuzuordnenden Arbeitsflächen angeordnet werden kann . Die Schaltungsanordnung sollte dabei auch dieThe invention was therefore based on the object to admit a circuit arrangement with which the consumers can be connected to the next generally available access to the supply network, in which, in addition to efnem switches on the consumer, no further manually operated switches are required and in which the Central connection point for the large number of consumers can be arranged at any point outside the work surfaces to be assigned to the consumers. The circuit arrangement should include the
Möglichkeit bieten , evtl entstehende, durch die zentrale Anschaltung der Verbraucher ausgelöste Störungen , wie z . B . Schaltimpulse und kurzzeitige Überlastung, im Verbraucherkreis zu unterdrücken .Offer the possibility of any malfunctions caused by the central connection of the consumers, such as: B. Switching impulses and short-term overload to suppress in the consumer circuit.
Diese A ufgabe wird bei einer Schaltungsanordnung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß ein erster Stromkreis vorgesehen ist, in welchen ein beliebig zu bestimmender erster elektrischer Verbraucher einfügbar ist; dessen Netzschalter als zu betätigender Schalter für die I nbetriebnahme al ler Verbraucher fungiert, daß ein zweiter, über einen elektrisch steuerbaren Schalter anschaltbarer zweiter Speisestromkreis vorgesehen ist, der eine der gewünschten Zahl weiterer Verbraucher entsprechende Anzahl von Netzanschlußdosen enthält und daß dem ersten Speisestromkreis ein den Schalter steuernder Stromsensor zugeordnet ist . Wesentlicher Teil der Erfindung ist es daher, allein aus der I nbetriebnahme eines der Verbraucher ein Steuersignal für das Anschalten der übrigen Verbraucher abzuleiten .This task is solved according to the invention in a circuit arrangement of the type mentioned at the outset in that a first circuit is provided in which a first electrical consumer which can be determined as desired can be inserted; whose mains switch acts as a switch for the commissioning of all consumers, a second supply circuit, which can be connected via an electrically controllable switch, is provided, which contains a number of mains connection sockets corresponding to the desired number of further consumers, and that the first supply circuit has a switch controlling current sensor is assigned. An essential part of the invention is therefore to derive a control signal for switching on the other consumers solely from the commissioning of one of the consumers.
Der Vorteil der neuen Schaltungsanordnung liegt darin , daß man aus einer Anzahl von gleichzeitig zu speisenden Verbauchern beliebig einen als zum ersten Stromkreis gehörenden bestimmen und mittels seines Netzschalters nicht nur ihn selbst sondern auch alle anderen Verbraucher an das speisende Netz anschalten bzw . von diesem abschalten kann , wobei die Netzschalter der letztgenannten Verbraucher stets in Einschaltstellung verbleiben können .The advantage of the new circuit arrangement lies in the fact that one of a number of consumers to be fed at the same time can be used to determine which one belongs to the first circuit, and by means of its power switch not only turn it on but also all other consumers to the feeding network. can switch off from this, the power switch of the latter consumer can always remain in the on position.
Die Schaltungsanordnung kann in einer Steckerleiste zusammengefaßt werden, die in herkömmlicher Weise an das speisende Netz angeschlossen wird . Sie kann nach Verbindung mit den Verbrauchern an beliebiger Stelle außerhalb des für die Bedienung der Verbraucher benötigten Arbeitsbereiches gelagert werden .The circuit arrangement can be summarized in a connector strip which is connected in a conventional manner to the supply network. After being connected to the consumers, it can be stored anywhere outside of the work area required to serve the consumers.
Um beim Schalten Stromspitzen zu vermeiden , kann dem Stromsensor ein Verzögerungsglied sowie ein im zweiten Speisestromkreis dem elektrisch steuerbaren Schalter nachgeordneter Einschaltstrombegrenzer nachgeschaltet sein . Auch kann wenigstens einem der Speisestromkreise ein EMV-Filter vorgeschaltet sein . In order to avoid current peaks when switching, the current sensor can be followed by a delay element and an inrush current limiter arranged downstream of the electrically controllable switch in the second supply circuit. An EMC filter can also be connected upstream of at least one of the supply circuits.
Ein Ausführungsbeispiel für die Erfindung ist in der Zeichnung schematisch dargestellt und nachfolgend beschrieben:An embodiment of the invention is shown schematically in the drawing and described below:
Wie gezeigt, sind zwei Speisestrorakreise 1 und 2 vorgesehen, die in Bezug auf das speisende Netz zueinander parallel geschaltet sind. Speisestromkreis 1 ist mit einer Steckdose 3 für einen ersten, einen Netzschalter aufweisenden Verbraucher versehen. Speisestromkreis 2 weist eine Vielzahl von Steckdosen 4 - 7 auf, die zueinander parallel geschaltet sind. Diesen ist ein elektrisch betätigbarer, zweipoliger Schalter 8 vorgelagert, welcher von einem dem Speisestromkreis 1 zugeordneten und von diesem erregten Stromsensor 9 gestaert wird.As shown, two power circuits 1 and 2 are provided, which are connected in parallel to one another with respect to the power supply network. Supply circuit 1 is provided with a socket 3 for a first consumer having a power switch. Supply circuit 2 has a plurality of sockets 4 - 7, which are connected in parallel to each other. This is preceded by an electrically actuable, two-pole switch 8, which is triggered by a current sensor 9 assigned to the supply circuit 1 and excited by it.
Die Funktion des soweit Beschriebenen ist wie folgt: Der Benutzer wählt aus den anzuschließenden und zu speisenden Verbrauchern einen aus, mittels dessen Netzschalter er auch die verbleibenden Verbraucher schalten will, und schließt diesen über die Steckdose 3 (master) an. Die übrigen Verbraucher werden an die Steckdosen 4 - 7 (slaves) angeschlossen und ihre Netzschalter - soweit vorhanden - auf Stellung "EIN" geschaltet.The function of what has been described so far is as follows: the user selects one from the consumers to be connected and fed, by means of whose power switch he also wants to switch the remaining consumers, and closes this via the socket 3 (master) on. The other consumers are connected to sockets 4 - 7 (slaves) and their mains switches - if available - are set to the "ON" position.
Schaltet nun der Benutzer den Verbraucher in Speisestromkreis 1 mittels dessen Netzschalters ein, so fließt im Speisestromkreis 1 ein Strom, auf welchen der Sensor 9 anspricht und den Schalter 8 in die StelLung "EIN" steuert. Damit sind alle Verbraucher allein durch Betätigung des Netzschalters des ersten Verbrauchers an Spannung gelegt.If the user now switches on the consumer in the supply circuit 1 by means of the mains switch, a current flows in the supply circuit 1, to which the sensor 9 responds and controls the switch 8 in the "ON" position. This means that all consumers are energized simply by actuating the power switch of the first consumer.
Bei Umschaltung dieses Netzschalters in Stellung "AUS" steuert der Stromsensor 9 den Schalter 8 in die andere Stellung und alle Verbraucher werden stromlos.When this power switch is switched to the "OFF" position, the current sensor 9 controls the switch 8 to the other position and all consumers are de-energized.
Um den Einschaltstromstoß beim gleichzeitigen Aufschalten einer Vielzahl von Verbrauchern zu mindern, kann im Speisestrorakreis hinter dem Schalter 8 ein Einschaltstrombegrenzer 10 vorgesehen werden, der über ein Zeltverzögerungsglied 11 vom Stromsensor 9 aus geschaltet wird.In order to reduce the inrush current when a plurality of consumers are switched on at the same time, an inrush current limiter 10 can be provided behind the switch 8 in the supply circuit which is switched by a current delay element 11 from the current sensor 9.
Ist die Minderung des Einschaltstromstoßes wegen der Vielzahl von nachgeordneten Verbrauchern (slaves) nicht ausreichend, so kann der Speisestromkreis 2 hinter dem Schalter 8 In parallele Zweige mit je einer Anzahl von Steckdosen 4 - 7 bzw. 4' - 7' usw. aufgeteilt werden, denen je ein eigener Einβchalts trombegrenzer 10 bzw. 10' usw. sowie je ein Zeitverzögerungsglied 11 bzw. 11' usw. zugeordnet sind. Dabei sind die Zeitverzögerungen unterschiedlich gewählt, so daß die Einschaltatrombe- grenzer nacheinander zur Wirkung kommen.If the reduction of the inrush current is not sufficient due to the large number of downstream consumers (slaves), the supply circuit 2 behind the switch 8 can be divided into parallel branches with a number of sockets 4 - 7 or 4 '- 7' etc., each of which has its own switch-on current limiter 10 or 10 ', etc., and a time delay element 11 or 11', etc. assigned. The time delays are selected differently so that the switch-on current limiters come into effect one after the other.
Schließlich kann es von Vorteil sein, wenigstens ein EMV-Filter 12 vorzusehen, welches die Übertragung von Störungen aus dem Netz auf die neue Schaltung bzw. aus der neuen Schaltung in das speisende Netz weitgehend verhindert. Es kann je nach Notwendigkeit einem der beiden Speisestromkreise, oder wie dargestellt, beiden Speisestromkreisen gemeinsam zugeordnet sein. Finally, it can be advantageous to provide at least one EMC filter 12, which largely prevents the transmission of interference from the network to the new circuit or from the new circuit to the supply network. Depending on the need, it can be assigned to one of the two supply circuits or, as shown, to both supply circuits together.
