Description

Die Erfindung betrifft eine Überspannungsableiteranordnung mit mehreren, in einem Gehäuse befindlichen Überspannungsableitern und interner Verdrahtung zum Schutz von Niederspannungssystemen, wobei das Gehäuse eine Unterseite besitzt, welche Ausnehmungen aufweist, durch die eine Vielzahl von elektrischen Steckkontakten geführt ist, gemäß Oberbegriff des Anspruches 1.The invention relates to a surge arrester arrangement with a plurality of surge arresters located in a housing and internal wiring for protecting low-voltage systems, the housing having an underside which has recesses through which a large number of electrical plug contacts are guided, according to the preamble of claim 1.

Aus der DE 10 2004 037 083 B4 ist eine Überspannungsableiteranordnung mit einer als Bestandteil eines Gehäuses ausführbaren Trägerplatte vorbekannt.From the DE 10 2004 037 083 B4 a surge arrester arrangement with a support plate that can be designed as part of a housing is already known.

Die Überspannungsableiter, welche insbesondere zum Schutz von Niederspannungsversorgungssystemen ausgelegt sind, werden elektrisch vorkonfektioniert auf der Trägerplatte oder im Gehäuse fixiert und mit externen Anschlussmitteln versehen. Zur unmittelbaren Montage auf ein Sammelschienensystem mit mehreren Stromschienen sind an oder in der Unterseite der Trägerplatte im Rasterabstand des Sammelschienensystems kupplungsartige Mittel zum elektrischen und mechanischen Verbinden angeordnet. Die interne elektrische Verdrahtung ist induktivitätsarm und stoßstromfest ausgelegt. Die Unterseite der Trägerplatte weist im Abstand der Stromschiene des Sammelschienensystems verlaufende nutförmige Rücksprünge oder Ausnehmungen auf, wobei in diesen Federkontaktelemente befestigt und geführt sind.The surge arresters, which are designed in particular to protect low-voltage supply systems, are electrically pre-assembled and fixed on the carrier plate or in the housing and are provided with external connection means. For direct mounting on a busbar system with several busbars, coupling-like means for electrical and mechanical connection are arranged on or in the underside of the carrier plate in the grid spacing of the busbar system. The internal electrical wiring is designed to be low inductance and resistant to surge currents. The underside of the carrier plate has groove-shaped recesses or recesses running at a distance from the busbar of the busbar system, with spring contact elements being fastened and guided in these.

Aus der DE 38 04 294 C1 ist ein Einspeiseadapter für ein Sammelschienensystem vorbekannt. Dieser Adapter dient dem elektrischen Verbinden von Anschlussleitungen mit den Sammelschienen, bei dem in einem auf die Sammelschienen aufsetzbaren Kunststoff-Adapterteil, auf die Sammelschienen ausgerichtet, jeweils ein Kontaktstück pro Sammelschiene gehalten ist, bei dem jedes Kontaktstück mittels einer U-förmigen Klammer elektrisch leitend mit der zugeordneten Sammelschiene verbindbar ist. Die Klammer hintergreift mit an den freien Enden ihrer Seitenschenkel angeformten Klemmenden die Sammelschiene. Eine in einer Gewindebohrung des Steges der Klammer verstellbare Klemmschraube verspannt die Sammelschiene mit dem Kontaktstück. Die Kontaktstücke sind außerhalb des Klemmbereiches der Klammer mit Gewindebohrungen zum Anschließen der Anschlussleitungen mittels Anschlussschrauben versehen. Durch die vorgeschlagene Anordnung der Kontaktstücke und der Klammern sowie der Anschlusskontakte für die Anschlussleitungen wird ein Anschlussadapter geschaffen, der auch bei einem Dreileiter-Sammelschienensystem mit minimalem Platzbedarf in Längsrichtung der Sammelschiene auskommt.From the DE 38 04 294 C1 a feed adapter for a busbar system is already known. This adapter is used for the electrical connection of connecting lines to the busbars, in which one contact piece per busbar is held in a plastic adapter part that can be placed on the busbars, aligned with the busbars, in which each contact piece is electrically conductive by means of a U-shaped clip the associated busbar can be connected. The clip engages behind the busbar with clamping ends molded onto the free ends of its side legs. A clamping screw that can be adjusted in a threaded hole in the web of the clamp braces the busbar with the contact piece. Outside the clamping area of the clamp, the contact pieces are provided with threaded holes for connecting the connecting cables using terminal screws. The proposed arrangement of the contact pieces and the clamps as well as the connection contacts for the connection lines creates a connection adapter which, even in the case of a three-wire busbar system, requires minimal space in the longitudinal direction of the busbar.

Weiterhin sind Einspeiseadapter für Sammelschienen vorbekannt, wobei beispielsweise auf den Typ K96ESA5 der Hager Elektro S.A. verwiesen werden soll. Ein derartiger Einspeiseadapter ist in der Lage, in seinen Anschlussleitungsöffnungen massive oder mehradrige Kupferleitungen mit oder ohne Aderendhülsen aufzunehmen, ohne dass eine Schraubklemme betätigt werden muss (siehe www.hagergroup.net).Furthermore, feed adapters for busbars are already known, for example the type K96ESA5 from Hager Elektro S.A. should be referred. Such a feed adapter is able to accommodate solid or multi-core copper cables with or without ferrules in its connecting cable openings without having to operate a screw terminal (see www.hagergroup.net).

Die US 2 595 658 A offenbart eine Überspannungsableiterschiene, umfassend eine Vielzahl von Überspannungsableitern, die mittels Anschlüssen elektrisch kontaktiert werden können. Die Überspannungsableiter sind in einem mehrteiligen Gehäuse untergebracht, das ein oberes Basisteil und ein unteres Basisteil aufweist. Das untere Basisteil hat mehrere Ausnehmungen, aus denen die Anschlüsse seitlich herausragen, wobei ein Teil der Anschlüsse eine abgewinkelte Form aufweist. Die Anschlüsse sind zudem von der Gehäuseunterseite isoliert.the U.S. 2,595,658 A discloses a surge arrester bar, comprising a multiplicity of surge arresters that can be electrically contacted by means of terminals. The surge arresters are housed in a multi-part housing that has an upper base part and a lower base part. The lower base has a plurality of recesses from which the terminals protrude laterally, with a portion of the terminals having an angled shape. The connections are also isolated from the underside of the housing.

Aus dem Vorgenannten ist es Aufgabe der Erfindung, eine Überspannungsableiteranordnung mit mehreren, in einem Gehäuse befindlichen Überspannungsableitern und interner Verdrahtung zum Schutz von Niederspannungssystemen anzugeben, wobei ausgehend von einem an sich bekannten Steckteil die Anordnung so weiterzubilden ist, dass ein unmittelbares elektrisches Kontaktieren und mechanisches Verbinden mit einem Einspeiseadapter erfolgen kann, ohne dass die Betätigung von Schraubklemmen erforderlich ist, so dass insgesamt eine werkzeugfreie Montage möglich wird.From the above, it is the object of the invention to specify a surge arrester arrangement with several surge arresters located in a housing and internal wiring for the protection of low-voltage systems, with the arrangement being based on a plug-in part known per se to be developed in such a way that direct electrical contact and mechanical connection can be done with a feed adapter without the need to operate screw terminals, so that overall tool-free assembly is possible.

Die Lösung der Aufgabe der Erfindung erfolgt durch die Überspannungsableiteranordnung gemäß der Merkmalskombination nach Anspruch 1, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen umfassen.The object of the invention is achieved by the surge arrester arrangement according to the combination of features according to claim 1, the subclaims comprising at least expedient configurations and developments.

Es wird demnach von einer Überspannungsableiteranordnung mit mehreren, in einem Gehäuse befindlichen Überspannungsableitern und entsprechender interner Verdrahtung ausgegangen. Die Überspannungsableiteranordnung dient insbesondere dem Schutz von Niederspannungssystemen.Accordingly, the starting point is a surge arrester arrangement with a plurality of surge arresters located in a housing and corresponding internal wiring. The surge arrester arrangement serves in particular to protect low-voltage systems.

Überspannungsableiter, insbesondere sogenannte Blitzstromableiter, werden vorzugsweise am Gebäudeeintritt im Hauptstrom-Versorgungssystem oder unmittelbar nach dem Zähler eingesetzt, um die nachgeordnete elektrische Installation von negativen Wirkungen des Blitzstoßstromes bzw. vor Überspannungen zu schützen.Surge arresters, in particular so-called lightning current arresters, are preferably used at the building entrance in the main power supply system or immediately after the meter in order to protect the downstream electrical installation from the negative effects of the lightning impulse current or from overvoltages.

Da einer der Haupteinkopplungswege dieser leitungsgebundenen Störgrößen die in das System eingeführten Leitungen selbst bilden, ist eine Installation der Schutzgeräte unmittelbar am Gebäudeeintritt erforderlich. Bei der Installation von Schutzgeräten ist insbesondere darauf zu achten, dass eine optimale Schutzwirkung erreicht werden kann, was im Übrigen auch in entsprechenden Installationsvorschriften festgelegt ist.Since one of the main coupling paths for these line-bound interference variables is the lines introduced into the system themselves, the protective devices must be installed directly at the point where they enter the building. When installing protective devices, it is particularly important to ensure that an optimal protective effect can be achieved, which is also specified in the corresponding installation regulations.

Stromschienensysteme bzw. Sammelschienensysteme zur Energieverteilung sind seit längerer Zeit aus dem Stand der Technik bekannt und haben sich im Einsatz nicht nur aufgrund ihrer Zuverlässigkeit, sondern auch wegen der gegebenen Flexibilität im Vergleich zu anderen Installationstechniken durchgesetzt.Conductor rail systems or busbar systems for power distribution have been known from the prior art for a long time and have become established in use not only because of their reliability but also because of the given flexibility compared to other installation techniques.

Werden Einspeiseadapter auf Sammelschienen aufgesetzt, beispielsweise Einspeiseadapter für Sammelschienen mit den Abmessungen 5 x 12 mm und einem Sammelschienenabstand von 40 mm, kann eine Kontaktierung der Sammelschienen in einfacher Weise vorgenommen werden.If feeder adapters are placed on busbars, for example feeder adapters for busbars with the dimensions 5 x 12 mm and a busbar spacing of 40 mm, the busbars can be contacted in a simple manner.

Geht man von einer Überspannungsableiteranordnung mit mehreren in einem Gehäuse befindlichen Überspannungsableitern und interner Verdrahtung aus, wobei das Gehäuse eine Unterseite besitzt, welche Ausnehmungen aufweist, durch die eine Vielzahl von elektrischen Steckkontakten geführt ist, greift der erfindungsgemäße Gedanke, die Steckkontakte nasenartig auszubilden und unter einem Winkel abweichend von der Senkrechten bezüglich der Gehäuseunterseite zu orientieren. Dabei werden die jeweiligen Steckkontakte je nach dem entsprechenden Überspannungsableiteranordnungstyp identisch ausgebildet.If one assumes a surge arrester arrangement with a plurality of surge arresters located in a housing and internal wiring, the housing having an underside which has recesses through which a large number of electrical plug-in contacts are guided idea according to the invention of forming the plug contacts like a nose and orienting them at an angle deviating from the vertical with respect to the underside of the housing. In this case, the respective plug contacts are of identical design, depending on the corresponding type of surge arrester arrangement.

Die nunmehr gleichsinnig schräg verlaufenden Steckkontakte können über eine horizontal zur Einspeiseadapterschiene ausgeführten Montagebewegung in die dortigen Leitungsaufnahmen eingeführt werden. Durch Schieben in leicht vertikaler Richtung nach unten erfolgt eine Verriegelung der Steckkontakte im entsprechenden, auf den Sammelschienen bereits aufgebrachten Einspeiseadapter.The plug contacts, which now run obliquely in the same direction, can be inserted into the line receptacles there by means of an assembly movement performed horizontally with respect to the feed adapter rail. By sliding it slightly vertically downwards, the plug contacts are locked in the corresponding feeder adapter already attached to the busbars.

Das Kontaktsystem kann sehr einfach ausgebildet werden, da nur Steckkontakte im Sinne von schrägen Stiften oder Nasen vorzusehen sind. Ebenso sind schrägstehende Anschlussbleche als Steckkontakte ausführbar.The contact system can be designed very simply, since only plug-in contacts in the sense of inclined pins or lugs are to be provided. Likewise, inclined connecting plates can be designed as plug-in contacts.

Bevorzugt sind die erfindungsgemäßen Steckkontakte starr ausgebildet und weisen einen runden Querschnitt auf.The plug contacts according to the invention are preferably rigid and have a round cross section.

In diesem Sinne können die Steckkontakte auch als Steck-Stiftkontakte realisiert werden.In this sense, the plug contacts can also be implemented as plug-pin contacts.

Die Schräglage, der Abstand untereinander, die Länge und der Querschnitt der Steckkontakte ist auf die Ausbildung eines an sich bekannten Einspeiseadapters für ein Sammelschienensystem ausgerichtet und diesbezüglich komplementär realisiert.The inclined position, the distance from one another, the length and the cross section of the plug contacts are geared to the formation of a feed adapter known per se for a busbar system and are implemented in a complementary manner in this respect.

Die Überspannungsableiteranordnung ist in diesem Sinne als ein kompaktes Modul zum unmittelbaren Stecken mit integrierter Verdrahtung realisiert. Die Anordnung kann eine Einzel- oder Sammelanzeige bezogen auf den Zustand der eingesetzten Überspannungsableiter aufweisen. Im selben Sinne ist eine Möglichkeit zum Anschluss an einer Fernmeldeeinrichtung vorgesehen.In this sense, the surge arrester arrangement is implemented as a compact module for direct plugging with integrated wiring. The arrangement can have an individual or collective display based on the status of the surge arresters used. In the same sense, a possibility for connection to a telecommunications device is provided.

Die interne Verdrahtung der Überspannungsableiteranordnung kann entsprechend der Netzform, zum Beispiel TT oder TN, realisiert werden.The internal wiring of the surge arrester arrangement can be implemented according to the type of network, for example TT or TN.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispieles sowie unter Zuhilfenahme von Figuren näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment and with the aid of figures.

Hierbei zeigen:

Here show:
  • 1 a representation of an indicated busbar system with a feed adapter not yet connected to the busbar system and a surge arrester arrangement according to the invention in the state of the assembly movement that has not yet taken place with regard to the line receptacles in the feed adapter;

  • 3 a representation of the state of the surge arrester arrangement connected to the feed adapter using the nose-like plug contacts present in the latter, which run at an angle deviating from the vertical with respect to the underside of the housing.

Die in den Figuren 1 bis 3 gezeigte Überspannungsableiteranordnung 1 weist mehrere, in einem Gehäuse befindliche Überspannungsableiter mit entsprechender interner Verdrahtung auf. Über im Gehäuse ausgebildete Fenster kann der Funktionszustand der eingesetzten Überspannungsableiter kontrolliert und angezeigt werden.The in the Figures 1 to 3 The surge arrester arrangement 1 shown has a plurality of surge arresters located in a housing with corresponding internal wiring. The functional status of the surge arresters used can be checked and displayed via windows in the housing.

Die Überspannungsableiteranordnung 1 dient insbesondere dem Schutz von Niederspannungssystemen.The surge arrester arrangement 1 serves in particular to protect low-voltage systems.

Da einer der Haupteinkopplungswege leitungsgebundener Störgrößen die in das System eingeführten Leitungen selbst bilden, ist eine Installation einer Überspannungsableiteranordnung unmittelbar am Gebäudeeintritt vorteilhaft.Since the lines introduced into the system form one of the main coupling paths of line-bound interference variables, it is advantageous to install a surge arrester arrangement directly at the building entrance.

Gebäudeseitig sind Stromschienensysteme mit mehreren Stromschienen zur Energieverteilung bekannt. Die Stromschienensysteme weisen normgerecht beabstandete Stromschienen mit entsprechenden ebenfalls der Norm unterliegenden Stromschienenabmessungen auf.On the building side busbar systems with several busbars for power distribution are known. The busbar systems have standard-compliant spaced busbars with corresponding busbar dimensions that are also subject to the standard.

Ein Einspeiseadapter 4 kann nun in an sich bekannter Weise auf die entsprechenden Sammelschienen des Stromschienensystems 3 aufgesetzt und durch Verschiebung mechanisch befestigt und elektrisch kontaktiert werden. Die entsprechenden Einspeiseadapter 4 weisen eine Vielzahl von Anschlussöffnungen 5 auf, die üblicherweise zum Auflegen von Kabelenden genutzt werden.A feed adapter 4 can now be placed in a manner known per se on the corresponding busbars of the busbar system 3 and mechanically fastened by displacement and electrically contacted. the Corresponding feed adapter 4 have a large number of connection openings 5, which are usually used for placing cable ends.

Die erfindungsgemäße Überspannungsableiteranordnung 1 besitzt eine Gehäuseunterseite, welche Ausnehmungen aufweist, durch die eine Vielzahl von elektrischen Steckkontakten 6 geführt sind.The surge arrester arrangement 1 according to the invention has a housing underside which has recesses through which a large number of electrical plug contacts 6 are guided.

Diese Steckkontakte 6 sind bevorzugt nasenartig ausgebildet und verlaufen unter einem Winkel abweichend von der Senkrechten bezüglich der Gehäuseunterseite der Überspannungsableiteranordnung 1. Die jeweiligen Steckkontakte sind je Anordnungstyp identisch ausgebildet. Beispielsweise weisen die Steckkontakte 6 einen runden Querschnitt auf und können als SteckStift-Kontakte ausgebildet werden.These plug contacts 6 are preferably nose-like and run at an angle deviating from the vertical with respect to the underside of the housing of the surge arrester arrangement 1. The respective plug contacts are of identical design for each type of arrangement. For example, the plug contacts 6 have a round cross section and can be designed as plug-in contacts.

Die Schräglage, der Abstand untereinander, die Länge und der Querschnitt der Steckkontakte 6 sind auf die Ausbildung des Einspeiseadapters 4 mit dortigen Öffnungen 5 ausgerichtet und entsprechend angepasst.The inclined position, the distance from one another, the length and the cross section of the plug contacts 6 are aligned with the configuration of the feed adapter 4 with openings 5 there and adapted accordingly.

Nachdem, wie in der Figur 2 gezeigt, der entsprechende Einspeiseadapter 4 auf das Sammelschienensystem 3 aufgesetzt wurde, wird die Überspannungsableiteranordnung 1 mit den gleichsinnig schräg verlaufenden Steckkontakten 6 über eine horizontal zur Einspeiseadapteranordnung 4 ausgeführten Montagebewegung in die dortigen Öffnungen 5, welche beispielsweise die erwähnten Leitungsaufnahmen sind, eingeführt. Durch Schieben in leicht vertikaler Richtung nach unten erfolgt dann eine Verriegelung der Steckkontakte 6 im entsprechenden, auf den Sammelschienen 3 bereits aufgebrachten Einspeiseadapter 4.After, as in the figure 2 shown, the corresponding feed adapter 4 has been placed on the busbar system 3, the surge arrester arrangement 1 with the plug contacts 6 running obliquely in the same direction is inserted into the openings 5 there, which are, for example, the cable receptacles mentioned, by means of an assembly movement carried out horizontally to the feed adapter arrangement 4. By pushing in a slightly vertical downward direction, the plug contacts 6 are then locked in the corresponding feed adapter 4 already attached to the busbars 3.
