Description
Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einem aus einer Rückwand und einem Vorderteil bestehenden Gehäuse und einem in diesem Gehäuse befindlichen Kontaktsystem, das wenigstens eine, zweckmäßig zwei etwa parallele, durch Befestigungsmittel fixierte, einschiebbare, aus einem profilierten Halbzeug hergestellte Anschlußschienen, zur Verbindung des Kontaktsystems mit einem äußeren Stromkreis aufweist, wobei sich die Anschlußschienen durch in der Rückwand befindliche Durchtrittsöffnungen erstrecken und durch Distanzstücke in dem Gehäuse positioniert sind und wobei ferner die eine der Anschlußschienen als Träger eines ortsfesten Schaltkontaktes und eines Lichtbogenhornes dient während die weitere der Anschlußschienen durch eine gelenkige oder flexible Leiteranordnung mit einem bewegbaren Schaltkontakt des Schaltkontaktsystems in Verbindung steht.The invention relates to a low-voltage circuit breaker with one consisting of a back wall and a front part Housing and located in this housing contact system, the at least one, expediently two approximately parallel, fixed by fasteners, retractable, from a profiled semi-finished produced connecting rails, for connecting the contact system to an external circuit having, wherein the connecting rails through in the Rear wall located openings extend through and Spacers are positioned in the housing and wherein Furthermore, one of the connecting rails as a carrier of a stationary Switching contact and an arcing horn is used during the other of the connecting rails by a hinged or flexible conductor arrangement with a movable switching contact the switch contact system is in communication.
Anschlußschienen von Leistungsschaltern sind die schalterseitigen Verbindungsstellen des Kontaktsystems zu den Schienensystemen der Schaltanlage. Sie werden entweder bei Festeinbauschaltern direkt oder bei Einschubschaltern über Lamellenkontakte mit den Sammel- bzw. Feldschienen der Schaltanlage verbunden. An dem aus dem Gehäuse nach außen hindurchgeschobenen Teil jeder Anschlußschiene kann also eine weitere, anlagenseitige Schiene angeschraubt werden oder bei Einschubschaltern ein Trennkontakt angebracht werden. Die obere Anschlußschiene mit dem festen Schaltkontakt muß dabei in dem isolierenden Wandkörper fest angeordnet sein, da beim Schaltvorgang die beweglichen Kontakte mit voller Kraft auf den festen Kontakt auftreffen.Connection rails of circuit breakers are the switch side Connection points of the contact system to the rail systems the switchgear. They will either be at fixed installation ages directly or with slide-in switches via lamellar contacts with the busbars or field busbars of the switchgear connected. At the pushed out of the housing to the outside Part of each connection rail can therefore be another, plant side Rail are bolted or slide-in switches a disconnect contact be attached. The upper connecting rail with the fixed switching contact must be in the insulating wall body be fixed, there during the switching process the moving contacts with full force on the solid Impact contact.
Die Anschlußschienen müssen weiterhin so gestaltet sein, daß sie rationell herstellbar sind und geeignet sind, bestimmte Funktionen zu erfüllen. Diese Funktionen sind: die Stromtragfähigkeit, die Wärmeabfuhr, eine Einfahrkontur für die Lamellenkontakte, eine Fläche für Frontanschlüsse sowie die Aufnahme und Übertragung der statischen und dynamischen Kräfte. Es handelt sich also um eine kräftemäßig und dynamisch hoch beanspruchte Stelle.The connection bars must continue to be designed so that they are rationally manufacturable and are capable of certain To fulfill functions. These features are: current carrying capacity, the heat dissipation, an entry contour for the lamellar contacts, a surface for front connections as well as the recording and transmission of static and dynamic forces. So it's a vigorous and dynamic high claimed place.
Darüber hinaus soll es möglich sein, verschieden dicke Anschlußschienen für unterschiedliche Stromstärken in einem einheitlichen Gehäuse unterzubringen.In addition, it should be possible, different thickness connecting rails for different currents in one housing uniform housing.
Als Befestigungsmittel für die Anschlußschiene dienen bei herkömmlichen Schaltern, wie zum Beispiel in der DE 44 16 105 beschrieben, Schrauben, die sich durch quer zur Längsachse der Anschlußschienen angeordnete Öffnungen erstrecken und für deren Aufnahme in der Rückwand des Gehäuses ein entsprechendes Muttergewinde vorgesehen ist. Aus Gründen der mechanischen Festigkeit der aus einem Isolierstoff bestehenden Rückwand des Gehäuses, werden hier metallische Einlegmuttern oder Einpreßmuttern verwendet.Serve as a fastener for the connecting rail conventional switches, such as in DE 44 16 105th described screws that are transverse to the longitudinal axis extend the connecting rails arranged openings and for their inclusion in the rear wall of the housing a corresponding Nut thread is provided. For the sake of mechanical Strength of the rear wall made of an insulating material of the housing, here are metallic Einlegmuttern or Pressed nuts used.
Bei den genannten Leistungsschaltern mit hohen Nennströmen von beispielsweise 1000 A bis 6000 A weisen die Anschlußschienen einen beträchtlichen Querschnitt auf. Deshalb sind sie mit mehreren Querbohrungen zu versehen und es ist eine entsprechende Anzahl von Befestigungsmitteln erforderlich. For the mentioned circuit breakers with high rated currents from, for example, 1000 A to 6000 A have the connection bars a considerable cross-section. That's why to provide them with several cross holes and it is one appropriate number of fasteners required.
Die Herstellung und der Einbau derartiger Anschlußschienen
ist folglich mit einem hohen Material- und Fertigungsaufwand
verbunden.
Es wurde deshalb die Verwendung von Anschlußschienen von Niederspannungs-Leistungsschaltern
vorgeschlagen, die von einem
Profilmaterial mit einem oder mehreren Vorsprüngen abgesägt
sind, derart, daß die Anschlußschienen durch ein Loch gesteckt
werden und der oder die Vorsprünge des Profilmaterials
als Anschläge der Anschlußschiene am Schaltergehäuse dienen
und somit die Kraftüberleitung der Schaltkräfte auf das Gehäuse
bilden.The production and installation of such connection bars is therefore associated with a high material and manufacturing costs.
It has therefore been proposed the use of connection bars of low-voltage circuit breakers, which are sawed off from a profile material with one or more projections, such that the connecting rails are inserted through a hole and serve or the projections of the profile material as stops of the connecting rail on the switch housing and thus form the force transfer of the switching forces on the housing.
Damit ist einmal die Position des Festkontaktes zum Gehäuse bestimmt und zum Anderen wird die Befestigungsstelle von den genannten Kräften entlastet, so daß hier nur eine Fixierkraft benötigt wird, eine Belastung durch die Scherkraft und die Positionisierungskraft aber nicht auftritt.This is once the position of the fixed contact to the housing determined and on the other hand, the attachment point of the relieved forces, so that here only a fixing force is required, a load by the shear force and the Positioning force does not occur.
Eine derartige Anschlußschiene, mit einem angeformten Vorsprung,
wurde zur Überwindung des vorgenannten Aufwandes in
der DE-196 43 607 A1, gemäß dem Oberbegriff des Patentanspruchs 1, vorgeschlagen. Diese Anschlußschiene
wird von innen durch die Durchführungsöffnung der Gehäusewand
gesteckt und stützt sich mittels eines Vorsprunges an der Gehäuserückwand
ab.Such a connecting rail, with an integrally formed projection,
was to overcome the aforementioned effort in
DE-196 43 607 A1, according to the preamble of
Zur Herstellung dieser Anschlußschiene werden besondere Profile verwendet, die eine einstückig angeformte Leiste aufweisen, von denen dann Stücke abgeschnitten werden, welche die Anschlußschiene bilden. Die Befestigung der Anschlußschiene erfolgt von der dem Schaltkontaktsystem zugewandten Seite. Das hat den Nachteil, daß die Befestigung bei zusammengebautem Schalter unzugänglich ist, und die Anordnung trotz der Verbesserungen, wie nicht mehr erforderliche Querbohrungen in den Anschlußschienen und verringertem Material- und Fertigungsaufwand, keine befriedigende Lösung darstellt.For the production of this connecting rail special profiles used, which have an integrally molded bar, from which then pieces are cut, which the Form connecting rail. The fastening of the connecting rail occurs from the switch contact system side facing. This has the disadvantage that the attachment when assembled Switch is inaccessible, and the arrangement despite the Improvements, such as no longer required cross holes in the connection rails and reduced material and production costs, does not represent a satisfactory solution.
Bei Leistungsschaltern mit einem Aufbau der Strombahn gemäß der DE 35 39 673 A1 oder der DE 196 43 607 A1 werden je nach dem Nennstrom verschieden dicke Anschlußschienen verwendet. Diese Anschlußschienen werden ebenfalls aus Profilen durch Absägen (längs oder quer) hergestellt. Das Gehäuse weist einheitliche Ausschnitte für die Anschlußschienen auf, die jeweils für die größte Nennstromstärke ausgelegt sind. Für dünnere Anschlußschienen kleinerer Nennstromstärken werden Distanzstücke aus Kunststoff verwendet, die die Zwischenräume füllen. Die Montage der Distanzstücke hat den Nachteil zusätzlicher Kosten für diese Teile sowie höherer Montagekosten und sie bilden eine Fehlerquelle bei einer kundenseitigen Montage der Strombahnen.For circuit breakers with a structure of the current path according to DE 35 39 673 A1 or DE 196 43 607 A1 are depending on the nominal current different thickness connecting rails used. These connection rails are also made of profiles Sawing (longitudinal or transverse) made. The housing has uniform Cutouts for the connecting rails on, respectively designed for the largest rated current. For thinner ones Connecting rails of smaller rated currents become spacers Made of plastic, which uses the interstices to fill. The mounting of the spacers has the disadvantage of additional Cost of these parts and higher installation costs and they form a source of error for a customer Assembly of the current paths.
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Anschlußschiene zu schaffen, die so ausgebildet ist, daß Anschlußschienen unterschiedlicher Stromstärken ohne zusätzliche Distanzstücke in Schaltergehäusen mit einheitlichen Durchgangsöffnungen eingesetzt werden können.The object of the present invention is therefore to to provide a connecting rail which is designed so that Connection rails of different currents without additional Spacers in switch housings with uniform Through openings can be used.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Anschlußschienen so gestaltet sind, daß die Distanzstücke als ein einstückiges Teil in die Anschlußschiene integriert sind.This object is achieved in that the Connecting rails are designed so that the spacers as a one-piece part are integrated into the connecting rail.
Das bedeutet, daß der "Nutzquerschnitt", also der Querschnitt des stromtragenden Teiles der Anschlußschiene, dem geforderten Bemessungsstrom entsprechend dünn gewählt wird und diese mittels der einstückig mit der Anschlußschiene ausgebildeten Distanzstücke in der einheitlich dem maximalen Nennstrom des jeweiligen Schaltertyps entsprechend ausgeführten Durchtrittsöffnung in der Rückwand des Niederspannungs-Leistungsschalters abgestützt wird. Da die Anschlußschienen aus einem profilierten Material durch einfaches Absägen hergestellt werden, erhält dieses zu diesem Zweck wenigstens zwei angeformte Stege, deren Abmessungen der Differenz zwischen der Dicke der verwendeten Anschlußschiene und der Größe der Durchtrittsöffnung in der Rückwand des Niederspannungs-Leistungsschalters entsprechen.This means that the "useful cross section", ie the cross section the current-carrying part of the connecting rail, the required Rated current is selected accordingly thin and this formed integrally with the connecting rail Spacers in the uniform the maximum rated current of the respective switch type appropriately designed passage opening in the back wall of the low-voltage circuit breaker is supported. Since the connecting rails from a profiled material produced by simple sawing For this purpose, it receives at least two integrals Webs whose dimensions are the difference between the Thickness of the used connecting rail and the size of the Passage opening in the rear wall of the low-voltage circuit breaker correspond.
Je nach gewünschtem Bemessungsstrom und der damit verbundenen größeren oder geringeren Dicke der Anschlußschiene sind diese Stege folglich mehr oder weniger hoch, um die Anschlußschiene in der Rückwand des Niederspannungs-Leistungsschalters exakt zu fixieren.Depending on the desired rated current and the associated larger or smaller thickness of the connecting rail are these Consequently, bars more or less high, around the connecting rail in the back wall of the low-voltage circuit breaker exactly to fix.
Die Durchtrittsöffnungen in der Schalterrückwand werden, wie schon erwähnt, dem maximalen Bemessungsstrom der jeweiligen Typenreihe des Niederspannungs-Leistungsschalters entsprechend ausgebildet.The openings in the switch rear wall are how already mentioned, the maximum rated current of the respective Type series of low-voltage circuit breaker accordingly educated.
Die Anschlußschienen sind mit Anschlägen zur axialen Positionierung im Gehäuse und zur Sicherung gegen ein axiales Verschieben versehen.The connecting rails are provided with stops for axial positioning in the housing and to secure against axial displacement Mistake.
Weiterhin sind Mittel zur Fixierung der Anschlußschienen an den Anschlägen vorgesehen. Das können zweckmäßig Zugschrauben sein. Es sind aber auch andere Mittel zur axialen Beaufschlagung der Anschlußschiene in die Richtung zum Anschlag und somit zur axialen Fixierung möglich.Furthermore, means for fixing the connection bars on provided for the attacks. That may be appropriate lag screws be. But there are also other means for axial admission the connecting rail in the direction of the stop and thus possible for axial fixation.

daß eine Anschlußschiene 2;3 mit dem höchstmöglichen
für den Nennstrom des Niederspannungs-Leistungsschalters 1
erforderlichen Querschnitt hindurchgeführt werden kann.The upper passage opening 10 and the lower passage opening
11 for the connecting
Wird der Niederspannungs-Leistungsschalter 1 nur für einen
geringeren Betriebsstrom ausgelegt, wird für die Anschlußschienen
2 und 3 lediglich ein geringerer Querschnitt benötigt.
Dann sind Distanzstücke 12; 13; 14; 15 erforderlich, um
die Differenz zwischen dem Querschnitt der Durchtrittsöffnungen
10;11 und den dünneren Anschlußschienen 2;3 auszugleichen.
Diese Distanzstücke sind entsprechend der vorliegenden
Erfindung einstückig in die Anschlußschienen integriert und
stützen diese sicher gegen die Rückwand 4 des Gehäuses des
Niederspannungs-Leistungsschalters ab. Die obere Anschlußschiene

Die Vorteile der erfindungsgemäßen Lösung bestehen darin daß keine zusätzlichen Teile- und Montagekosten für Distanzstücke benötigt werden. Das ergibt einen zusätzlichen Kundenvorteil, durch eine vereinfachte Montage der Strombahn, bei der Montagefehler weitgehend ausgeschlossen sind. Darüber hinaus ergibt sich durch die vergrößerte Oberfläche der Anschlußschiene ein günstigeres Temperaturverhalten des Schalters.The advantages of the solution according to the invention are that no additional parts and assembly costs for spacers needed.
