Abstract
Description
Die Erfindung betrifft ein Überspannungsschutzgerät zur Hutschienenmontage mit in einem Gehäuse angeordneten gekapselten Funkenstrecken in zylindrischer Bauform, wobei am Überspannungsschutzgerät zwei gegenüberliegende Außenanschlussklemmreihen vorgesehen sind, wobei hier eine erste Klemmreihe L1 bis Ln sowie N eine zweite Klemmreihe PE-Anschlüsse aufweist, weiterhin umfassend interne Anschluss- und Verbinderflächen sowie zwischen den Funkenstrecken angeordnete Trennwände oder Trennabstände gemäß Oberbegriff des Anspruchs 1, wie aus
Überspannungsschutzgeräte in kompakter Bauform, welche in einem Kunststoffgehäuse mehrere Funkenstrecken nebst peripherer Triggerelektronik aufweisen, gehören zum Stand der Technik.Surge protection devices in a compact design, which have a plurality of spark gaps along with peripheral trigger electronics in a plastic housing, belong to the prior art.
Bei einer derartigen Überspannungsschutzgeräte-Ausführung der Firma DEHN + SÖHNE GmbH + Co. KG, Neumarkt, befinden sich in einer Bodenwanne des Außengehäuses liegend nebeneinander mehrere gekapselte Funkenstrecken. Bei einer so genannten 3+1- bzw. 1+1-Verschaltung liegen die Anschlüsse L1 bis Ln der Netzfunkenstrecken und der Anschluss N auf einer Verdrahtungsseite des Geräts, wobei hingegen sich der PE-Anschluss auf der gegenüberliegenden Verdrahtungsseite befindet. Eine derartige Ausbildung der Anschlusselemente ist zum externen Verdrahten eines Überspannungsschutzgeräts von besonderem Vorteil.In such a surge protective device version of DEHN + SÖHNE GmbH + Co. KG, Neumarkt, lying in a floor pan of the outer housing lying side by side several encapsulated spark gaps. In the case of a so-called 3 + 1 or 1 + 1 connection, the connections L 1 to L n of the network spark gaps and the connection N are located on one wiring side of the device, whereas the PE connection is on the opposite wiring side. Such a design of the connection elements is for external wiring of a surge protective device of particular advantage.
Um nun unter Beachtung der notwendigen Verschaltung die gewünschte Funktion des Überspannungsschutzgeräts sicherzustellen, ist es notwendig, eine interne Kontaktbrücke N/PE auszubilden.In order to ensure the desired function of the surge protective device, taking into account the necessary interconnection, it is necessary to form an internal contact bridge N / PE.
Bei einer Prinzipanordnung gemäß Fig. 1, die den vorstehend kurz erläuterten Stand der Technik darstellt, ist ersichtlich, welchen Verlauf die Ströme im Überspannungsfall einnehmen.
Unter Beachtung der Tatsache, dass auf parallele Leiter, welche gegensinnig von elektrischen Strömen durchflossen werden, aufgrund der auftretenden elektromagnetischen Felder abstoßende Kräfte entstehen, ist es notwendig, die N/PE-Brücke gemäß dem Stand der Technik sicher im Gehäuse festzulegen, so dass die auftretenden Kräfte beherrschbar sind. Gemäß der Darstellung nach Fig. 1 ist der Bereich zwischen der N/PE-Brücke und der N/PE-Funkenstrecke besonders kritisch, da sich hier die größten Ströme gegenüberstehen. Unter der Annahme, dass i1 = i2 = i3 = i4 gilt, ist die abstoßende Kraft zwischen der N/PE-Brücke und der N/PE-Funkenstrecke circa 12 mal größer als z.B. die anziehende Kraft zwischen den beiden Netzfunkenstrecken der Pfade L1 und L2 unter der Voraussetzung, dass jeweils nur die Felder der direkt benachbarten Ströme berücksichtigt werden.In a principle arrangement according to FIG. 1, which represents the prior art briefly explained above, it can be seen which course the currents take in the case of overvoltage.
Taking into account the fact that on parallel conductors, which are in opposite directions flows through electric currents, due to the occurring electromagnetic Fields arise repulsive forces, it is necessary to securely set the N / PE bridge according to the prior art in the housing, so that the forces are manageable. According to the illustration according to FIG. 1, the area between the N / PE bridge and the N / PE spark gap is particularly critical, since here the largest currents are located. Assuming that i 1 = i 2 = i 3 = i 4 , the repulsive force between the N / PE bridge and the N / PE spark gap is approximately 12 times greater than, for example, the attractive force between the two network spark gaps Paths L 1 and L 2 , provided that only the fields of the directly adjacent streams are taken into account.
Da die Kraft zwischen der N/PE-Brücke und der N/PE-Funkenstrecke bei entsprechend großen Strömen aufgrund der Produktbildung gemäß der in Fig. 1 dargestellten Beziehung ebenfalls sehr groß wird, ist bei einer derartigen liegenden Anordnung ein sehr hoher konstruktiver Aufwand an die Gehäusefestigkeit zu stellen.Since the force between the N / PE bridge and the N / PE spark gap with correspondingly large currents due to the product formation according to the relationship shown in FIG. 1 is also very large, is in such a horizontal arrangement a very high design complexity of the Housing strength to ask.
Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, ein weiterentwickeltes Überspannungsschutzgerät zur Hutschienenmontage mit in einem Gehäuse angeordneten gekapselten Funkenstrecken in zylindrischer Bauform anzugeben, wobei das Überspannungsschutzgerät auf eine 3+1- bzw. 1+1-Schaltung zurückgeht. Bei dem zu realisierenden Überspannungsschutzgerät sollen unerwünschte stromflussbedingte Kräfte vermieden werden, so dass der Aufwand für das Fixieren der Funkenstrecken und der notwendigen Anschluss- und Verbinderflächen innerhalb eines Kompaktgehäuses minimierbar ist.From the foregoing, it is therefore an object of the invention to provide a further developed overvoltage protection device for DIN rail mounting arranged in a housing encapsulated spark gaps in a cylindrical design, the surge protection device goes back to a 3 + 1 or 1 + 1 circuit. In the overvoltage protection device to be realized, unwanted current-flow-related forces should be avoided, so that the outlay for fixing the spark gaps and the necessary connection and connector surfaces within a compact housing can be minimized.
Die Lösung der Aufgabe der Erfindung erfolgt mit einem Überspannungsschutzgerät gemäß der Merkmalskombination nach Anspruch 1, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen darstellen.The object of the invention is achieved with a surge protection device according to the combination of features according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.
Erfindungsgemäß sind die einzelnen Funkenstrecken stehend angeordnet, so dass nicht die Notwendigkeit besteht, eine N/PE-Brücke vorzusehen. Durch den Vorteil des Wegfalls der Brücke tritt die beim Stand der Technik vorliegende elektromagnetische Kraft nicht auf, so dass die konstruktiven und mechanischen Anforderungen an die Stabilität des Gehäuses geringer sind mit der Folge eines reduzierten Kostenaufwands bei der Herstellung von Überspannungsschutzgeräten in einem Kompaktgehäuse.According to the invention, the individual spark gaps are arranged upright so that there is no need to provide an N / PE bridge. Due to the advantage of the omission of the bridge, the present in the prior art electromagnetic force does not occur, so that the structural and mechanical requirements for the stability of the housing are lower with the result a reduced cost in the manufacture of surge protectors in a compact enclosure.
Die gekapselten Funkenstrecken werden wie vorerwähnt stehend auf einer ersten internen Anschluss- und Verbinderfläche fixiert. Diese erste Fläche verläuft im Wesentlichen parallel zum Gehäuseboden des Überspannungsschutzgeräts, wobei die erste Anschluss- und Verbinderfläche mit dem N-Anschluss der ersten Klemmreihe vom elektrischen Außenanschluss in Verbindung steht.The encapsulated spark gaps are fixed as mentioned standing on a first internal connection and connector surface. This first surface extends substantially parallel to the housing bottom of the overvoltage protection device, wherein the first connection and connector surface is in communication with the N-terminal of the first terminal row from the external electrical connection.
Zweite bis n-te interne Anschluss- und Verbinderflächen gemäß L1 bis Ln stehen jeweils mit der Oberseite der jeweiligen Funkenstrecke und dem jeweiligen L1 bis Ln-Anschluss der ersten Klemmreihe in Verbindung.Second to nth internal terminal and connector surfaces according to L 1 to L n are in each case with the top of the respective spark gap and the respective L 1 to L n terminal of the first terminal row in connection.
Eine weitere, auf der ersten Anschluss- und Verbinderfläche stehende Funkenstrecke, nämlich die N/PE-Funkenstrecke, weist ebenfalls eine Anschluss- und Verbinderfläche auf ihrer Oberseite auf, welche zum PE-Anschluss der zweiten Klemmreihe führt, die der ersten Klemmreihe an der entsprechenden Gehäuselängsseite gegenüberliegt.Another, on the first connection and connector surface spark gap, namely the N / PE spark gap, also has a connection and connector surface on its upper side, which leads to the PE terminal of the second terminal row, the first terminal row at the corresponding Opposite shell side opposite.
Die L1 bis Ln-Funkenstrecken sind nahe der ersten Klemmreihe und die PE-Funkenstrecke ist nahe der zweiten Klemmreihe befindlich.The L 1 to L n spark gaps are close to the first clamp row and the PE spark gap is near the second clamp row.
Oberhalb der stehend angeordneten Funkenstrecken mit den jeweiligen Anschluss- und Verbinderflächen ist eine Isolierplatte vorgesehen, auf welcher sich eine Leiterplatte mit der Funkenstrecken-Triggerelektronik befindet.Above the standing arranged spark gaps with the respective connection and connector surfaces, an insulating plate is provided, on which there is a circuit board with the spark gap trigger electronics.
Das Gehäuse des Kompaktgeräts weist in einer bevorzugten Ausführungsform eine im Wesentlichen quadratische bzw. rechteckige Form auf und besitzt eine Bodenwanne, wobei die Funkenstrecken stehend in der Bodenwanne angeordnet und dort elektrisch kontaktiert sind.In a preferred embodiment, the housing of the compact device has a substantially square or rectangular shape and has a bottom trough, wherein the spark gaps are arranged standing in the bottom trough and electrically contacted there.
Zwischen der Leiterplatte und dem jeweiligen metallischen Mantel der jeweiligen Funkenstrecke ist bei entsprechendem Erfordernis ein Triggerfederkontakt angeordnet, welcher sich in einer Führungsausnehmung der Isolierplatte befindet.Between the printed circuit board and the respective metallic sheath of the respective spark gap a trigger spring contact is arranged with a corresponding requirement, which is located in a guide recess of the insulating plate.
Die Anschluss- und Verbinderflächen sind als metallisches Stanz-Biegeteil ausgeführt und weisen eine hohe Stromtragfähigkeit auf.The connection and connector surfaces are designed as a metal stamped and bent part and have a high current carrying capacity.
Durch die Anordnung der Funkenstrecken in stehender Weise mit an den Stirnseiten der zylindrischen Mäntel jeweils befindlichen Anschlusselementen kann bei der gewünschten 3+1-Verschaltung ein antiparalleler Stromfluss durch die zum Anschluss und zur Kontaktierung notwendigen Leiter verhindert werden.The arrangement of the spark gaps in a standing manner with each located on the end faces of the cylindrical shells connecting elements can be prevented in the desired 3 + 1 interconnection an antiparallel current flow through the necessary for connection and contacting conductors.
