Niederspannungs-LeistungsschalterLow-voltage circuit breakers
Die Erfindung betrifft einen Niederspannungs-Leistungsschal- ter mit einer ersten Kontaktanordnung zur Verbindung eines ortsfesten Kontaktes mit einer ersten Stromschiene und mit einer zweiten Kontaktanordnung zur Verbindung eines an einem Kontakthebel angeordneten Gegenkontaktes mit einer zweiten Stromschiene.The invention relates to a low-voltage circuit breaker with a first contact arrangement for connecting a fixed contact to a first busbar and with a second contact arrangement for connecting a mating contact arranged on a contact lever to a second busbar.
Niederspannungs-Leistungsschalter der genannten Art verfügen über Kontaktanordnungen, um ein schnelles Verbinden beziehungsweise Trennen des Schalters mit stromführenden Schienen zu ermöglichen. Dies ist unter anderem zum Ausbau oder zur Wartung der Niederspannungs-Leistungsschalter wünschenswert. Niederspannungs-Leistungsschalter werden für unterschiedliche Nennströme in unterschiedlichen Größen vorgesehen. Dabei wird angestrebt, die baulichen Abmaße eines Niederspannungs-Leis- tungsschalters möglichst gering zu halten.Low-voltage circuit breakers of the type mentioned have contact arrangements to enable the switch to be connected or disconnected quickly to live rails. Among other things, this is desirable for the removal or maintenance of the low-voltage circuit breakers. Low-voltage circuit breakers are designed for different nominal currents in different sizes. The aim is to keep the structural dimensions of a low-voltage circuit breaker as small as possible.
Niederspannungs-Leistungsschalter der genannten Art können einerseits als Festeinbau-Schalter, andererseits als Ein- schub-Schalter ausgeführt sein. Bei Einschub-Schaltern wird der Leistungsschalter in einem dafür vorgesehenen Einschubrahmen bewegt und arretiert. Dies ermöglicht ein schnelleres und einfacheres Verbinden beziehungsweise Trennen des Leistungsschalters von den Stromschienen als beim Festeinbau- Schalter. Daher ist es wünschenswert, Festeinbau-Schalter mit einem möglichst geringen Material- und Arbeitsaufwand in Ein- schub-Schalter umrüsten zu können.Low-voltage circuit breakers of the type mentioned can on the one hand be designed as fixed installation switches and on the other hand as plug-in switches. With plug-in switches, the circuit breaker is moved and locked in a plug-in frame provided for this purpose. This enables the circuit breaker to be connected and disconnected from the busbars more quickly and easily than with the fixed installation switch. It is therefore desirable to be able to convert fixed installation switches into plug-in switches with as little material and labor as possible.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Nie- derspannungs-Leistungsschalter der vorgenannten Art anzuge- ben, welcher mit minimalem Material- und Arbeitsaufwand von einem Festeinbau-Schalter in einen Einschubschalter umrüstbar ist. Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale im kennzeichnenden Teil des Anspruchs 1 im Zusammenwirken mit den Merkmalen im Oberbegriff des Anspruchs 1.It is therefore an object of the present invention to provide a low-voltage circuit breaker of the aforementioned type which can be converted from a fixed installation switch into a plug-in switch with minimal expenditure on material and labor. This object is achieved according to the invention by the features in the characterizing part of claim 1 in cooperation with the features in the preamble of claim 1.
Besonders vorteilhaft an der vorliegenden Erfindung ist, dass die bereits vorhandenen Stromschienen eines Festeinbau-Schal¬ ters für die Umrüstung in einen Einschub-Schalter auf einfachste Art und Weise wieder verwendet werden können. Dazu weisen die Stromschienen eines Niederspannungs-Leistungs- schalters Formmerkmale auf, wodurch der Niederspannungs-Leis- tungsschalter sowohl als Festeinbau-Schalter als auch als • Einschub-Schalter ausführbar ist.It is particularly advantageous in the present invention that the already existing busbars of a fixed- mounting switch can be reused in the simplest way for the conversion into a plug-in switch. For this purpose, the busbars of a low-voltage circuit breaker have shape features, as a result of which the low-voltage circuit breaker can be designed both as a fixed installation switch and as a plug-in switch.
In einer bevorzugten AusführungsVariante weisen die Stromschienen mindestens einen Kontaktbereich auf, über welchen die Stromschienen dauerhaft an einem Einschubrahmen eines Niederspannungs- eist ngsschaltexs anordbar sind. Weiterhin weisen die Stromschienen mindestens einen Aufnahmebereich für Haltemittel auf, über welchen die Stromschienen dauerhaft an einem Einschubrahmen eines Niederspannungs-Leistungsschalters anordbar sind.In a preferred embodiment variant, the busbars have at least one contact area, via which the busbars can be permanently arranged on a slide-in frame of a low-voltage power switch. Furthermore, the busbars have at least one receiving area for holding means, via which the busbars can be permanently arranged on a slide-in frame of a low-voltage circuit breaker.
In einer bevorzugten Ausführungsvariante sind der Aufnahmebe- reich für Haltemittel und der Kontaktbereich derart ausgebil¬ det, dass die Stromschienen dauerhaft, jedoch reversibel, an einem Einschubrahmen eines Niederspannungs-Leistungsschalters anordbar sind.In a preferred embodiment of the Aufnahmebe- det are so rich ausgebil ¬ for holding means and the contact area, that the busbars, but reversibly, to a slide part of a low-voltage circuit breaker are permanently locatable.
Durch die vorgenannte Ausführung der Stromschienen wird es ermöglicht, diese zur Verwendung in einem Festeinbau-Schalter direkt am Festeinbau-Schalter anzuordnen, jedoch ist es auch möglich, diese Stromschienen bei einer Umrüstung des Festeinbau-Schalters in einen Einschub-Schalter nach Ausbau aus dem Festeinbau-Schalter an den Einschubrahmen ' eines Einschub- Schalters dauerhaft anzuordnen, so dass die Umrüstung eines Festeinbau-Schalters in einen Einschub-Schalter mit minimalem Materialaufwand einhergeht, da für diese Umrüstung lediglich ein zusätzlicher Einschubrahmen notwendig ist. Durch den vor¬ gesehenen Kontaktbereich können die Stromschienen direkt am Einschubrahmen angeordnet werden. Dabei sollen die Flächen des Kontaktbereiches mit der zu kontaktierenden Fläche des Einschubrahmens plan abschließen. Dadurch, dass die Strom¬ schienen einen Aufnahmebereich für Haltemittel aufweisen, sind sie dauerhaft mit einem Haltemittel beaufschlagbar und können hierdurch dauerhaft am Einschubrahmen eines Leistungs- Schalters arretiert werden.The aforementioned design of the busbars makes it possible to arrange them for use in a fixed installation switch directly on the fixed installation switch, but it is also possible to convert these fixed rails into a slide-in switch after removal from the fixed installation -Switch on the slide-in frame 'of a slide-in switch to be permanently arranged, so that the conversion of a fixed switch into a slide-in switch with minimal Material costs go hand in hand, since this conversion only requires an additional slide-in frame. By seen before ¬ contact region, the bus bars can be arranged directly on the guide frame. The surfaces of the contact area should be flush with the surface of the slide-in frame to be contacted. Characterized in that the current rails have ¬ a receiving area for holding means they are permanently acted upon by a holding means and can thereby be permanently locked to the slide-in frame of a power switch.
In einer besonders bevorzugten Ausführungsform weisen sowohl die erste als auch die zweite Stromschiene identische Abmaße auf. Hierdurch wird vorteilhafterweise erreicht, dass sowohl für die erste Stromschiene als auch für die zweite Stromschiene die gleichen Kontaktanordnungen, welche vorzugsweise als Trennkontakt-Anordnungen ausgeführt sind, verwendet werden können.In a particularly preferred embodiment, both the first and the second busbar have identical dimensions. This advantageously ensures that the same contact arrangements, which are preferably designed as isolating contact arrangements, can be used both for the first busbar and for the second busbar.
Nach einer weiteren bevorzugten Ausführungsvariante sind die Stromschienen am Einschubrahmen derart anordbar, dass der Einschubrahmen die gleiche Einbautiefe wie die Stromschienen in einem Festeinbau-Schalter aufweist. Hierdurch wird gewährleistet, dass die Stromschienen lediglich über Haltemittel an ihren dafür vorgesehenen Bereichen an dem Einschub-Schalter dauerhaft angeordnet werden müssen, um eine Umrüstung vom Festeinbau-Schalter in einen Einschub-Schalter zu realisieren. Dadurch, dass die an einem Einschubrahmen angeordneten Stromschienen die gleiche Einbautiefe wie die Stromschienen beim Festeinbau-Schalter aufweisen, sind keine weiteren An- passungs- oder Umbauarbeiten notwendig.According to a further preferred embodiment variant, the busbars can be arranged on the slide-in frame in such a way that the slide-in frame has the same installation depth as the busbars in a fixed installation switch. This ensures that the conductor rails only have to be permanently arranged on the plug-in switch in their intended areas by means of holding means in order to convert from the fixed switch to a plug-in switch. Since the busbars arranged on a slide-in frame have the same installation depth as the busbars in the fixed installation switch, no further adaptation or conversion work is necessary.
In einer besonders bevorzugten AusführungsVariante sind die Stromschienen tellerförmig bzw. flügeiförmig ausgebildet. Die Erfindung soll nachstehend anhand von zumindest teilweise in den Figuren dargestellten Ausführungsbeispielen näher erläutert werden. Es zeigen:In a particularly preferred embodiment variant, the busbars are plate-shaped or wing-shaped. The invention will be explained in more detail below on the basis of exemplary embodiments shown at least in part in the figures. Show it:

Weiterhin weist der Leistungsschalter 10 eine zweite Kontaktanordnung 34 zur Verbindung einer zweiten Stromschiene 30 mit einem an einem Kontakthebel 14 angeordneten Gegenkontakt 16 auf. Der Niederspannungs- Leistungsschalter 10 ist in Figur 1 als Festeinbau-Schalter ausgeführt, indem die beiden Stromschienen 22 und 30 die zur Verbindung mit nicht weiter dargestellten anlagenseitigen Stromschienen dienen an der Außenseite der Rückwand des Leistungsschalters 10 befestigt sind. Zu dieser Befestigung dienen erste Haltemittel 12 die erste Auf ahmebereiche 20 der Stromschienen durchgreifen. Die Verbindung mit den anlagenseitigen Stromschienen erfolgt über nicht dargestellte zweite Haltemittel, die zweite Aufnahmebereiche 13 der Stromschienen 22 und 30 durchgreifen.As can be seen from FIG. 1, a low-voltage circuit breaker 10 has a first contact arrangement 24, which establishes a connection between a first stationary contact 18 arranged on a connecting bar 17 and a first current bar 22. Furthermore, the circuit breaker 10 has a second contact arrangement 34 for connecting a second busbar 30 to a mating contact 16 arranged on a contact lever 14. The low-voltage circuit breaker 10 is embodied in FIG. 1 as a fixed installation switch, in that the two busbars 22 and 30, which are used for connection to system-side busbars (not shown), are fastened to the outside of the rear wall of the circuit breaker 10. For this attachment, first holding means 12 are used to reach through the first receiving regions 20 of the busbars. The connection to the system-side busbars takes place via a second, not shown Holding means which pass through the second receiving areas 13 of the busbars 22 and 30.
Um die Vielfalt der notwendigen Schalterteile zu verringern und damit Herstellungskosten zu sparen, sind die Anschluss¬ schiene 17 und die Stromschienen 22 und 30 identisch ausge¬ bildet,' wobei' der Aufnahmebereich 13 der Anschlussschiene 17 zur Aufnahme eines vierten Haltemittels 15 dient. Das vierte Haltemittel 15 dient zur Fixierung eines Lichtbogenhornes 19 an der Anschlussschiene 17.The diversity of the necessary switch parts to decrease, and thus to save manufacturing cost, the connection ¬ are rail 17 and the conductor rails forms 22 and 30 identically ¬, 'which', the receiving region 13 of the connecting bar 17 serves for receiving a fourth holding means 15th The fourth holding means 15 is used to fix an arcing horn 19 to the connecting bar 17.
Die erste Stromschiene 22 und die zweite Stromschiene 30, welche erfindungsgemäß den Aufnahmebereich 20 für Halteiαittel und einen Kontaktbereich 38 zur Anordnung der Stromschienen 22, 30 an einem Einschubrahmen 11 des Leistungsschalter 10 aufweisen, kontaktieren den Leistungsschalter 10 mit ihrer dem Leistungsschalter 10 zugewandten Seite. Der Aufnahmebereich 20 ist als Durchgangsbohrung ausgeführt. Der Kσntaktbereich 38 befinden sich auf der dem Leistungsschalter 10 abgewandten Seite der Stromschienen 22, 30.The first S tromschiene 22 and the second bus bar 30, which according to the invention the receiving area 20 for Halteiαittel and a contact area 38 for the arrangement of the busbars 22, 30 have, at an insertion frame 11 of the circuit breaker 10, contact the circuit breaker 10 with their circuit-breaker 10 side facing. The receiving REA 20 is designed as a through bore. The contact area 38 is located on the side of the busbars 22, 30 facing away from the circuit breaker 10.
Durch den Kontaktbereich 38 ist es möglich, die erfindungsge¬ mäßen Stromschienen 22, 30 eines Festeinbau-Schalters, wie in Fig. 1 und Fig. 2 dargestellt, aus dem Festeinbau-Schalter auszubauen und an einem Einschubrahmen 11 eines Leistungs¬ schalters 10 anzuordnen, wie in Fig. 3 dargestellt ist. Wei¬ terhin können die so an dem Einschubrahmen 11 angeordneten Stromschienen 22, 30 durch dritte Haltemittel 35 dauerhaft arretiert werden. Die Haltemittel realisieren über die Auf- nahmebereiche 20 für Haltemittel eine dauerhafte, kraft¬ schlüssige Verbindung zwischen den Stromschienen 22, 30 und dem Einschubrahmen 11, wie in Fig. 4 dargestellt ist.Due to the contact area 38, it is possible that erfindungsge ¬ MAESSEN bus bars 22, 30 of a fixed built-in switch, as shown in Fig. 1 and Fig. 2, extend from the fixed-mounted switch and arrange a power ¬ switch 10 on a withdrawable frame 11, as shown in Fig. 3.
