Die Erfindung bezieht sich auf eine Schaltgerätekombination aus vorgeordneten Hauptgeräten, mit elektronischem Informationsver­ arbeitungsteil, auf der Seite eines Versorgungsnetzes, gege­ benenfalls mit Fernauslösung, und aus nachgeordneten Zweigge­ räten in einzelnen Verbraucherzweigen.The invention relates to a switchgear and controlgear assembly upstream main units, with electronic information ver work part, on the side of a supply network, opp also with remote triggering, and from subordinate branches advise in individual consumer branches.

Bei Sicherheitseinrichtungen und bei Schutzschaltsystemen, ins­ besondere mit umfangreicher Elektronik, wird technisch bedingt keine absolute Zuverlässigkeit erzielt. Bei elektronischen Ge­ räten ist insbesondere die Ausfallrate von Bauelementen zu be­ rücksichtigen und gegebenenfalls durch Schaltungsredundanzen auszugleichen.For safety devices and protective switching systems, ins special with extensive electronics, is due to technical reasons no absolute reliability achieved.

Zur Lösung der geschilderten Aufgabe ist nach der Erfindung vorgesehen, daß den Zweiggeräten elektronische Kontrollgeräte zur Überwachung der Auslösung zugeordnet sind, die mit dem In­ formationsverarbeitungsteil eines schaltungsgemäß zugeordneten Hauptgerätes verbunden sind. Bei Schaltgerätekombinationen und insbesondere bei Kombinationen von Schutzschaltgeräten, wird dadurch die Zuverlässigkeit hinsichtlich der Auslösung erheb­ lich erhöht, da zusätzlich zur Elektronik und auch zur Mecha­ nik, beispielsweise dem Schaltschloß, eine Redundanz geschaltet wird. Bei Schutzschaltgeräten können insbesondere elektronische Geräte, wie netzabhängige Differenzstromschutzschalter, aber auch netzunabhängige Fehlerstromschutzschalter in der Sicher­ heit ihres Abschaltverhaltens erhöht werden. To solve the problem described is according to the invention provided that the two-device electronic control devices assigned to monitor the triggering, which are associated with the In formation processing part of an associated circuit Main unit are connected. With switchgear assemblies and especially with combinations of protective switching devices thereby increasing the reliability with regard to tripping Lich increased, because in addition to the electronics and also to the Mecha nik, such as the switch lock, switched a redundancy becomes. In the case of protective switching devices, in particular electronic ones Devices, such as line-dependent residual current circuit breakers, however also mains-independent residual current circuit breakers in the safety their shutdown behavior can be increased.  

Die Hauptgeräte können insbesondere ein selektiver Differenz­ stromschutzschalter sein und die Zweiggeräte Differenzstrom­ schutzschalter. Die Hauptgeräte können auch selektive Fehler­ stromschutzschalter und die Zweiggeräte Fehlerstromschutz­ schalter sein. Das Hauptgerät kann allgemein ein netzunab­ hängiger Schutzschalter in Kombination mit einem elektroni­ schen Schutzschalter sein und die Zweiggeräte gleichfalls je­ weils Kombinationen aus netzunabhängigen Schutzschaltern und elektronischen Schutzschaltern sein.The main units can in particular make a selective difference be circuit breaker and the branch devices residual current circuit breaker. The main units can also selective errors circuit breaker and the branch devices residual current protection be switch. The main unit can generally be off-grid pending circuit breaker in combination with an electroni be the circuit breaker and the branch devices because combinations of off-circuit breakers and electronic circuit breakers.

Die Erfindung soll anhand von in der Zeichnung grob schema­ tisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:The invention is based on roughly in the drawing schematic table illustrated embodiments explained in more detail will:

In Fig. 1 ist eine Schaltgerätekombination mit gesonderten me­ chanischen Baugruppen und gesonderten elektronischen Geräte­ teilen veranschaulicht.In Fig. 1, a switching device combination with separate me mechanical assemblies and separate electronic devices share is illustrated.

In Fig. 2 ist eine Schaltgerätekombination wiedergegeben, deren Geräte jeweils mechanische und elektronische Bauteile inte­ griert enthalten.In Fig. 2, a switchgear and controlgear assembly is shown, the devices of which each contain integrated mechanical and electronic components.

Im Ausführungsbeispiel nach Fig. 1 ist in einer Hauptleitung 1 ein Hauptgerät 2 angeordnet. Seine Funktion wird erreicht durch eine elektromechanische Baugruppe 3 eines Schutzschalters und durch ein elektronisches Teil 4 für Informationsverarbeitung und zur Auslösung der elektromechanischen Baugruppe 3. Die Haupt­ leitung 1 verzweigt sich zu Verbraucherzweigen 5, in denen Zweiggeräte 6 angeordnet sind. Im Ausführungsbeispiel sind die Zweiggeräte 6 in ihrer Funktion durch elektromechanische Bau­ gruppen 7 von Schutzschaltern und durch elektronische Bauteile 8 jeweils zum Auslösen einer elektromechanischen Baugruppe 7 realisiert. Diesen Zweiggeräten 6 ist jeweils ein elektroni­ sches Kontrollgerät 9 zugeordnet. Die elektronischen Kontroll­ geräte 9 sind mit dem elektronischen Teil für die Informations­ verarbeitung und zur Auslösung des Hauptgerätes 2 verbunden. Das Hauptgerät ist vorzugsweise als selektives Gerät ausge­ legt.In the embodiment of Fig. 1, a main unit 2 is arranged in a main conduit 1. Its function is achieved by an electromechanical assembly 3 of a circuit breaker and by an electronic part 4 for information processing and for triggering the electromechanical assembly 3 . The main line 1 branches to consumer branches 5 , in which branch devices 6 are arranged. In the exemplary embodiment, the branch devices 6 are implemented in their function by electromechanical construction groups 7 of circuit breakers and by electronic components 8 for triggering an electromechanical assembly 7 . Each of these two devices 6 is assigned an electronic control device 9 . The electronic control devices 9 are connected to the electronic part for processing information and for triggering the main device 2 . The main device is preferably laid out as a selective device.

Bei einer Schaltgerätekombination aus netzspannungsunabhängigen Fehlerstromschutzschaltern oder aus netzspannungsabhängigen Differenzstromschutzschaltern weisen diese vorzugsweise hin­ sichtlich des Nenndifferenzstromes und der zeitlichen Auslö­ sung ein selektives Verhalten auf. So kann man vorzugsweise wegen der Aufsummierung von natürlichen Ableitströmen in den Verbraucherzweigen 5 und um ein sicheres Betriebsverhalten für die Hauptgeräte 2 sicherzustellen, einen Nenndifferenzstrom von größer oder gleich 100 mA vorsehen und für die Zweiggeräte Nenndifferenzströme kleiner oder gleich 30 mA. Solche Zweig­ geräte bieten Schutz bei direktem Berühren.In the case of a switchgear and controlgear assembly consisting of residual current circuit breakers which are independent of the mains voltage or of residual current circuit breakers which are dependent on the mains voltage, these preferably have a selective behavior with regard to the nominal residual current and the time-related triggering. For example, because of the summation of natural leakage currents in the consumer branches 5 and to ensure safe operating behavior for the main devices 2 , a nominal residual current of greater than or equal to 100 mA can be provided and nominal differential currents less than or equal to 30 mA for the branch devices. Such branch devices offer protection against direct contact.

Versagt beispielsweise im ersten linken Verbraucherzweig 5 ein elektronisches Teil des elektronischen Bauteils 8, so erfolgt im Fehlerfall ohne die erfindungsgemäße Maßnahme keine Abschal­ tung. Durch die vorgesehene Lösung wird durch das elektronische Kontrollgerät 9 jedoch die Abschaltung des Hauptgerätes 2 sichergestellt. Die Geräte können vorzugsweise so ausgelegt sein, daß bis zum Ansprechen des Hauptgerätes 2 nach Ausfall eines Zweiggeräts 6 eine Zeitspanne von 100 ms verstreicht. Die Verbindungsleitungen 10 zwischen den Kontrollgeräten 9 und dem elektronischen Teil 4 für Informationsverarbeitung und zur Aus­ lösung des Hauptgerätes können als Informationsbus ausgeführt sein.Denied, for example, in the first consumer branch left 5 an electronic part of the electronic component 8 so done in case of failure without the inventive measure pipe does not switching off. The proposed solution, however, ensures that the main device 2 is switched off by the electronic control device 9 . The devices can preferably be designed such that a time period of 100 ms elapses before the main device 2 responds after the failure of a two device 6 . The connecting lines 10 between the control devices 9 and the electronic part 4 for information processing and for triggering the main device can be designed as an information bus.

Das Hauptgerät 2 kann netzspannungsabhängig mit Elektronik ausgeführt sein und mit Zweiggeräten 6 aus netzspannungsunab­ hängigen Fehlerstromschutzschaltern mit zusätzlichen elektro­ nischen Kontrollgeräten 9 zusammenarbeiten. Ein netzspannungs­ unabhängiges Hauptgerät 2 kann auch mit netzspannungsabhängigen Zweiggeräten 6 oder mit auch netzspannungsunabhängigen Zweig­ geräten, beispielsweise Fehlerstromschutzschaltern, zusammen­ arbeiten. Es lassen sich also Differenzstromschutzschalter und Fehlerstromschutzschalter kombinieren, wobei die Sicher­ heit hinsichtlich Auslösung erhöht ist. Haupt- und Zweiggeräte können auch so ausgewählt sein, daß hinsichtlich der Fehler­ stromart ein ergänzender Schutz erzielt wird. So können wechselstromsensitive, pulsstromsensitive und allstromsensi­ tive Geräte entsprechend kombiniert werden.The main unit 2 can be designed with electronics depending on the line voltage and can work with two devices 6 from line voltage-independent residual current circuit breakers with additional electronic control devices 9 . A main device 2 that is independent of the mains voltage can also work together with two devices 6 that are dependent on the mains voltage or with branch devices that are also independent of the mains voltage, for example residual current circuit breakers. So residual current circuit breakers and residual current circuit breakers can be combined, whereby the safety with regard to tripping is increased. Main and branch devices can also be selected so that additional protection is achieved with regard to the fault current type. This means that AC-sensitive, pulse-current-sensitive and AC / DC-sensitive devices can be combined accordingly.

Bei der Schaltgerätekombination nach Fig. 2 sind sowohl das Hauptgerät 2 als auch die Zweiggeräte 6 hinsichtlich ihrer Geräteteile zusammenhängend ausgeführt, also integriert. Zu­ geordnet ist den Zweiggeräten 6 jeweils ein elektronisches Kontrollgerät 9. Dieses kann an den Zweiggeräten 6 vorzugsweise angebaut sein.In the switching device combination according to FIG. 2, both the main device 2 and the branch devices 6 are designed to be coherent with respect to their device parts, that is to say integrated. The two devices 6 are each assigned an electronic control device 9 . This can preferably be attached to the two devices 6 .

Das Nichtabschalten eines Zweiggerätes 6 oder auch des Haupt­ gerätes 2 kann zusätzlich optisch oder akustisch als auch optisch und akustisch durch Überwachungselektronik gemeldet werden.The non-shutdown of a branch device 6 or the main device 2 can also be reported optically or acoustically as well as optically and acoustically by monitoring electronics.

Die Schaltgerätekombinationen eignen sich besonders für intel­ ligente Verteilungssysteme.The switchgear and controlgear assemblies are particularly suitable for intel ligent distribution systems.
