The invention relates to an arrangement for use in an electrical Installation system, with a multi-phase switching device for use on a busbar system and overvoltage protection devices.

Dieses ist für den Einsatz zylindrischer Sicherungen geeignet und weist in einer Reihe quer zum Schienensystem angeordnete Schaltkontakte mit jedem Schaltkontakt zugeordneter Sicherung auf.

In Installationsanlagen finden Schutzschaltungsanordnungen Verwendung. Diese sollen sicherstellen, dass die Anlage selbst, Teile von ihr oder daran angeschlossene Verbraucher vor den Auswirkungen der Abweichungen von den normalen Betriebsbedingungen geschützt sind. Zum Schutz vor Störungen, welche aus dem Versorgungsnetz auf die Anlage einwirken, zum Beispiel Überspannungen, sind Schaltungsanordnungen mit Einrichtungen für den Überspannungsschutz, insbesondere Überspannungsableiter vorgesehen. Handelsübliche Überspannungsableiter weisen in ihrem Aufbau häufig eine Funkenstrecke, einen spannungsabhängigen Widerstand oder eine Schmelzsicherung als Abtrennvorrichtung auf.In installation installations, protective circuit arrangements are used. These Make sure that the plant itself, parts of it or attached to it Consumers from the effects of deviations from protected under normal operating conditions. To protect against interference, which act on the system from the supply network, for example overvoltages, are circuit arrangements with devices for overvoltage protection, in particular surge arrester provided. commercial Surge arresters often have a spark gap in their structure, a voltage dependent resistor or a fuse as Separator on.

Einrichtungen für den Überspannungsschutz sind beispielsweise bekannt aus "DEHN + SÖHNE, Überspannungsschutz, Hauptkatalog 2002, Druckschrift Nr. DS 570/2002 - www.dehn.de". Derartige Einrichtungen für den Überspannungsschutz werden auf Hutschienen montiert, wobei bei Verwendung einer entsprechenden Anzahl von Einrichtungen für den Überspannungsschutz gegenüber dem Bezugspotential eines N-Leiters und/oder eines PE-Leiters gegen Überspannungen abgesichert werden kann. Solche in Hutschienen gelagerte Einrichtungen für den Überspannungsschutz werden mittels Kabeln angeschlossen. Dies ist einerseits sehr aufwendig, andererseits kann eine solche Verkabelung dann, wenn sie im Zusammenhang mit einem Schaltgerät erfolgen soll, wegen der Kabelverbindung nicht in unmittelbarer Nähe des Schaltgerätes erfolgen. Devices for overvoltage protection are known, for example, from "DEHN + SÖHNE, Surge Protection, Main Catalog 2002, Publication No. DS 570/2002 - www.dehn.de ". Such devices for overvoltage protection are mounted on top hat rails, which can be secured against overvoltages when using a corresponding number of devices for overvoltage protection against the reference potential of an N-conductor and / or a PE conductor. Such over-voltage protection devices mounted in DIN rails are connected by means of cables. On the one hand, this is very expensive, but on the other hand such a wiring, if it is to take place in connection with a switching device, does not take place in the immediate vicinity of the switching device because of the cable connection.

In der DE 200 04 593 U1 ist ein Sammelschienensystem mit einer oder mehreren Stromschienen, die mittels eines Überspannungsableiters mit einem Bezugspotential verbindbar sind, beschrieben. Eine quer auf die Sammelschiene aufsetzbarere Adapterbrücke weist für die Kontaktierung der Stromschienen einen stromstoßfeststen Kontakt und wenigstens einen Steckplatz auf, der zumindest einen elektrisch mit dem Kontakt der Stromschiene verbundenen Steckkontakt hat. Der Überspannungsableiter ist als Steckmodul zur entsprechenden Aufnahme in dem Steckplatz der Adapterbrücke ausgebildet und hat wenigstens einen mit dem Steckkontakt in Eingriff bringbaren Gegenkontakt sowie ferner einen Bezugspotentialanschluss, der mit einem Bezugspotential verbindbar ist.In DE 200 04 593 U1 is a busbar system with one or more Busbars, by means of a surge arrester with a reference potential are connectable described. One across the busbar attachable adapter bridge points for contacting the busbars a shockproof contact and at least one slot, at least one electrically connected to the contact of the busbar Plug contact has.

Eine Anordnung zur Verwendung bei einer elektrischen Installationsanlage mit den Merkmalen des Oberbegriffes des Patentanspruchs 1 ist aus der EP-A-1 139 533 bekannt.An arrangement for use in an electrical installation with the features of the preamble of claim 1 is known from EP-A-1 139,533 known.

Aufgabe der vorliegenden Erfindung ist es, eine Anordnung zur Verwendung bei einer Installationsanlage zu schaffen, bei der mit minimalem Aufwand eine elektrische Verbindung von Schaltgerät und Sammelschienensystem sowie Schaltgerät und Einrichtungen für den Überspannungsschutz hergestellt werden kann. Die Positionierung der Einrichtungen für den Überspannungsschutz soll in unmittelbarer Nähe des Schaltgerätes möglich sein.The object of the present invention is to provide an arrangement for use in an installation to create, with minimal effort an electric Connection of switching device and busbar system as well Switching device and devices for surge protection are produced can. The positioning of the overvoltage protection devices should be possible in the immediate vicinity of the switching device.

Gelöst wird die Aufgabe durch eine Anordnung zur Verwendung bei einer elektrischen Installationsanlage mit den Merkmalen des Patentanspruches 1.The object is achieved by an arrangement for use in an electrical Installation system with the features of claim 1.

Diese Gestaltung ermöglicht es, die beiden, grundsätzliche funktionelle Einheiten bildende Module zu einer Einheit zu kombinieren, die die Funktion des mehrphasigen Schaltgerätes und die des Überspannungsschutzes beinhaltet. Es ist nicht erforderlich, die Einrichtungen für den Überspannungsschutz mit dem mehrphasigen Schaltgerät zu verdrahten. Innerhalb des Gehäuses angeordnete starre Leiter, insbesondere starre, dem Zugang zugeordnete Leiter, ermöglichen es, das Schaltgerät und die Einrichtungen für den Überspannungsschutz dicht an dicht einfach zu positionieren und die elektrisch leitenden Verbindungen zwischen den beiden Modulen unmittelbar herbeizuführen oder aber in der Steckposition der Leiter diese durch Schrauben zu klemmen. Entsprechende Klemmaufnahmen für die dem Schaltgerät zugeordneten Leiter der Einrichtungen für den Überspannungsschutz sind vorzugsweise in das Schaltgerät integriert. Grundsätzlich ist es aber ausreichend, die elektrisch leitende Verbindung zwischen dem dem Zugang zugeordneten Leiter der jeweiligen Einrichtung für den Überspannungsschutz und dem zugeordneten Abgang des Schaltgerätes unter Einwirkung einer Federklemmkraft zu bewirken, so dass die Erzeugung einer Klemmkraft mittels einer Schraube nicht erforderlich ist.This design allows the two basic functional units forming modules to combine the function of the includes multi-phase switching device and the overvoltage protection. It is not necessary to use the devices for surge protection to wire the multiphase switching device. Within the housing arranged rigid conductors, in particular rigid conductors assigned to the access, allow it, the switching device and the devices for surge protection easy to position and electrically conductive Connections between the two modules immediately or but in the plug position of the conductor to clamp them by screws. Appropriate Klemmaufnahmen for the switch associated conductor of the Devices for overvoltage protection are preferably in the switching device integrated. Basically, it is sufficient, the electrically conductive Connection between the access associated conductor of the respective device for overvoltage protection and the associated outflow of the Switching device under effect of a spring clamping force, so that the Generation of a clamping force by means of a screw is not required.

Das Gehäuse weist beispielsweise ein Unterteil und ein Oberteil auf. Ansätze am Gehäuseunterteil ermöglichen ein einfaches Aufstecken des Gehäuseunterteils auf das Sammelschienensystem. Sind die beiden Module dicht an dicht positioniert und die elektrisch leitende Verbindung zwischen den beiden Modulen hergestellt, kann die aus den beiden Modulen gebildete Einheit auf das Sammelschienensystem aufgesteckt werden. Es ist demzufolge nur noch die Verbindung des bzw. der Abgänge der Einrichtungen für den Überspannungsschutz mit dem Bezugspotential herzustellen. Der Handlingaufwand ist hierbei äußerst gering. Vorzugsweise werden die beiden Module als Einheit, somit elektrisch bereits verbunden, ausgeliefert, so dass der Anwender die Einheit nur noch auf das Sammelschienensystem aufstecken und die Verbindung zum Bezugspotential herstellen muss. Diese Gestaltung der Anordnung schließt somit fehlerhafte Anschlüsse der Einrichtungen für den Überspannungsschutz am Schaltgerät und am Bezugspotential wirksam aus. The housing has, for example, a lower part and an upper part. approaches on the lower part of the housing allow easy attachment of the housing base on the busbar system. Are the two modules close to each other? positioned and the electrically conductive connection between the two modules manufactured, the unit formed from the two modules on the Busbar system are plugged. It is therefore only the Connection of the outlet (s) of the overvoltage protection devices to produce with the reference potential. The handling effort is here extremely low. Preferably, the two modules as a unit, thus electrically already connected, shipped, leaving the user the unit only still plug onto the busbar system and the connection to the reference potential must produce. This configuration of the arrangement thus concludes faulty connections of the overvoltage protection devices on the Switching device and effective at the reference potential.

Eine vorteilhafte Aufnahme und Lagerung der Bauteile des zweiten Moduls ergibt sich, wenn die Leiter im Gehäuseunterteil gelagert sind und das Gehäuseoberteil Aufnahmen für die Einrichtungen für den Überspannungsschutz aufweist. Nach der Montage des Moduls sind die Leiter im wesentlichen innerhalb des Gehäuses angeordnet und es sind die Einrichtungen für den Überspannungsschutz von außen durch die Aufnahmen in das Gehäuseoberteil eingesteckt, wobei sie die Zu- und Abgänge der Leiter kontaktieren. Die starren Leiter sind abgangsseitig vorzugsweise in Klemmen eingesteckt, so dass dort eine einfache Verbindung zum Bezugspotential mittels eines flexiblen oder starren Leiters erfolgen kann.An advantageous reception and storage of the components of the second module results itself, when the conductors are mounted in the lower housing part and the upper housing part Has recordings for the devices for the overvoltage protection. After mounting the module, the conductors are essentially inside arranged the housing and it is the devices for the surge protection inserted from the outside through the receptacles in the upper housing part, whereby they contact the entrances and exits of the conductors. The rigid ladder are the output side preferably inserted into terminals, so there is a easy connection to the reference potential by means of a flexible or rigid Ladder can be done.

Die jeweilige Einrichtung für den Überspannungsschutz kann im Überspannungsfall wirksam werdende Auslösemittel aufweisen, deren Bewegung dazu führt, dass ein in die Einheit integrierter Fernauslöser aktiviert wird, der das Ansprechen des Überspannungsschutzes an eine Überwachungseinheit meldet. Die Einrichtung für den Überspannungsschutz kann ferner mit einem Störmelder versehen sein, der eine Störung des Überspannungsschutzes meldet.The respective device for overvoltage protection can in the event of overvoltage Have effective release means, their movement to causes a built-in remote unit to activate the unit of overvoltage protection to a monitoring unit reports. The device for overvoltage protection can also be equipped with a fault indicator be provided that reports a fault in the surge protection.
