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 comprising a plurality of surge arresters located in a housing and internal wiring for protecting low-voltage systems, wherein the housing has a lower side, which has recesses through which a plurality of electrical plug contacts is 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 is a surge arrester arrangement with an executable as part of a housing carrier plate previously 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 for the protection of low-voltage supply systems, are fixed electrically prefabricated on the support plate or in the housing and provided with external connection means. For direct mounting on a busbar system with multiple busbars clutch-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.

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 is a feed adapter for a busbar system previously known. This adapter is used for electrically connecting connecting cables to the busbars, in which one contact piece per busbar is held in a plastic adapter piece which can be placed on the busbars and aligned with the busbars, in which case each contact piece is electrically conductive by means of a U-shaped bracket can be connected to the associated busbar. The clip engages behind the busbar with molded on the free ends of their side legs clamping ends. An adjustable in a threaded bore of the web of the clamp clamping screw clamps the busbar with the contact piece. The contacts are provided outside the clamping area of the bracket with threaded holes for connecting the connecting cables by means of terminal screws. The proposed arrangement of the contact pieces and the brackets and the connection contacts for the connection lines, a connection adapter is created, which manages even with a three-wire busbar system with minimal space requirement 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, supply adapters for busbars are previously known, for example, the type K96ESA5 Hager Elektro S.A. should be referenced. Such a feed adapter is able to accommodate massive or multicore copper wires with or without wire end ferrules in its connection line openings, without the need for a screw terminal (see www.hagergroup.net).

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 foregoing, it is an object of the invention to provide a surge arrester arrangement with multiple, located in a housing surge arresters and internal wiring for the protection of low voltage systems, starting from a known plug-in part, the arrangement is to be developed so that a direct electrical contacting and mechanical connection can be done with a feed adapter, without the operation of screw terminals is required, so that a total of a tool-free installation 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 feature combination according to claim 1, wherein the dependent claims comprise at least expedient refinements 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.It is therefore of a surge arrester arrangement with several, located in a housing surge arresters and corresponding internal wiring. The surge arrester arrangement is used in particular for the protection of 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 entrance to the building in the main power supply system or immediately after the counter in order to protect the downstream electrical installation from negative effects of the lightning impulse current or against 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 of these conducted disturbances form the lines introduced into the system itself, it is necessary to install the protection devices immediately at the building entrance. When installing protective devices, particular care must be taken to ensure that optimum protection can be achieved, which is also specified in the relevant 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.Busbar systems or busbar systems for power distribution have long been known from the prior art and have prevailed 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 supply adapters are mounted on busbars, for example, supply adapters for busbars with the dimensions 5 x 12 mm and a busbar distance of 40 mm, a contacting of the busbars can be made 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.Assuming a surge arrester arrangement comprising a plurality of surge arresters and internal wiring located in a housing, wherein the housing has a bottom, which has recesses through which a plurality of electrical plug contacts is guided, the idea according to the invention, the plug contacts form nose-like and under a Angle deviating from the vertical with respect to the bottom of the housing to orient. The respective plug contacts are formed identically depending on the corresponding Überspannungsableiteranordnungstyp.

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 now in the same direction obliquely extending plug contacts can be introduced via a horizontally running to the feed adapter mounting movement in the local line recordings. By sliding in a slightly vertical downward direction locking of the plug contacts takes place in the corresponding, already applied to the busbars feeder adapter.

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 made very simple, since only plug contacts in the sense of oblique pins or noses are provided. Similarly, inclined connecting plates are designed as plug contacts.

Bevorzugt sind die erfindungsgemäßen Steckkontakte starr ausgebildet und weisen einen runden Querschnitt auf.Preferably, the plug contacts according to the invention are 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 realized 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 skew, the distance between them, the length and the cross-section of the plug contacts is aligned with the formation of a known feed adapter for a busbar system and implemented in this respect complementary.

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.The surge arrester arrangement is realized in this sense as a compact module for direct insertion with integrated wiring. The arrangement may have a single or collective display based on the state of the surge arrester 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 realized according to the network form, 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 below with reference to an embodiment and with the aid of figures.

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 Steck-Stift-Kontakte ausgebildet werden.These plug contacts 6 are preferably nose-like and extend at an angle deviating from the vertical with respect to the housing underside of the surge arrester 1. The respective plug contacts are formed identically for each arrangement type. For example, the plug contacts 6 have a round cross section and can be formed as plug-pin contacts.
