Description

Die Erfindung betrifft eine Stromschiene, insbesondere aus Metall, mit einem im Wesentlichen U-förmigen Querschnitt, bei der in den einen Aufnahmekanal seitlich begrenzenden parallelen Seitenwänden Tragschienen aus Isolierstoff angeordnet sind, die jeweils mehrere voneinander isolierte, in Schienenlängsrichtung parallel zueinander und einander gegenüberliegende und vom Aufnahmekanal zugängliche nicht isolierte, blanke elektrische Leiter aufnehmen, von denen drei als Phasenleiter und einer als Nullleiter geschaltet ist, wobei zudem vorzugsweise an der Basis der Stromschiene ein ebenfalls vom Aufnahmekanal zugänglicher Schutzleiter vorgesehen ist.The invention relates to a busbar, in particular of metal, having a substantially U-shaped cross-section, in which a receiving channel laterally bounding parallel side walls mounting rails are arranged made of insulating material, each isolated from each other, in the rail longitudinal direction parallel to each other and opposite and from Receive channel accessible non-insulated, bare electrical conductors record, of which three is connected as a phase conductor and a neutral conductor, wherein also preferably at the base of the busbar a likewise accessible from the receiving channel protective conductor is provided.

Eine derartige Stromschiene ist beispielsweise in Figur 3 der DE OS 22 50 738 ersichtlich.Such a busbar is for example in Figure 3 of DE OS 22 50 738 seen.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Stromschiene gattungsgemäßer Art zu schaffen, die neben dem Drehstrombetrieb auch den zusätzlichen Anschluss von weiteren Verbrauchern oder von Signalübertragungen ermöglicht.Based on this prior art, the present invention seeks to provide a busbar generic type, in addition to the Three-phase operation also allows the additional connection of other consumers or signal transmissions.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass zwischen jeweils einem Leiterpaar, welches in einer Tragschiene gehalten ist, ein fünfter und sechster blanker Leiter isoliert von den Leitern des Leiterpaares angeordnet ist, wobei der fünfte und sechste Leiter einander gegenüber liegen und vom Aufnahmekanal her zugänglich sind, wobei der fünfte und sechste Leiter als Steuerleiter für eine elektrische oder elektronische Steuerung oder als zusätzliche Versorgungsleiter für weitere elektrische Verbraucher geschaltet sind.To solve this problem it is proposed that between each pair of conductors, which is held in a support rail, a fifth and sixth bare conductor is arranged insulated from the conductors of the conductor pair, wherein the fifth and sixth conductors are opposite each other and accessible from the receiving channel wherein the fifth and sixth conductors are connected as control conductors for an electric or electronic control or as additional supply conductors for further electrical consumers.

Durch diese Anordnung wird ermöglicht, dass nicht nur die drei Phasenleiter und der Nullleiter als Anschluss für die Phasen bei Drehstrombetrieb genutzt werden können, sondern zusätzlich kann durch den fünften und sechsten Leiter die Einschaltung von zusätzlichen Verbrauchern, beispielsweise für Notlicht, Sicherheitsbeleuchtung, sonstige Verbraucher im Niederspannungsbetrieb oder auch im Wechselstrombetrieb, Signalübertragung und dergleichen erfolgen. Der Anwendungsbereich der Stromschiene wird damit erheblich erweitert.This arrangement allows not only the three phase conductors and the neutral can be used as a connection for the phases in three-phase operation, but also by the fifth and sixth conductor, the involvement of additional consumers, such as emergency, security lighting, other consumers in the Low-voltage operation or even in AC operation, signal transmission and the like done. The scope of application of the busbar is thus considerably expanded.

In an sich bekannter Weise kann dabei vorgesehen sein, dass an dem der Basis der Stromschiene abgewandten Endbereich der Seitenwände Auflagebereiche für einen in die Stromschiene eingesetzten Adapter ausgebildet sind, wobei vorzugsweise einer dieser Auflagebereiche einen blanken Schutzleiter hält, der vom Aufnahmekanal her zugänglich ist.In a manner known per se, it can be provided that on the end region of the side walls facing away from the base of the busbar, bearing areas for one in the busbar Adapters are formed, wherein preferably one of these support areas holds a bare protective conductor, which is accessible from the receiving channel ago.

Die Anordnung eines weiteren Schutzleiters in einem dieser Auflagebereiche ist eine Option, die je nach Ausgestaltung des mit der Stromschiene kompartiblen Adapters vorzusehen ist. Üblicherweise ist ein Schutzleiter an der Basis der Stromschiene außermittig angeordnet, wie aus dem oben zitierten Stand der Technik bekannt. Zusätzlich oder alternativ kann ein Schutzleiter in dem Auflagebereich der Stromschiene angeordnet sein.The arrangement of a further protective conductor in one of these support areas is an option that must be provided depending on the design of the adapter compatible with the busbar. Usually, a protective conductor is arranged off-center at the base of the busbar, as known from the prior art cited above. Additionally or alternatively, a protective conductor may be arranged in the support region of the busbar.

Um eine Anordnung zu schaffen, bei der Kriechspannungen zwischen den Phasenleitern, dem Nullleiter und dem fünften und sechsten Leiter auszuschließen sind, wird vorgesehen, dass jede Tragschiene aus Isolierstoff eine durch einen ersten Seitensteg, einen Mittelsteg und einen zweiten Seitensteg begrenzte Kammer zur Aufnahme jeweils eines Phasenleiters und/oder Nullleiters aufweist, wobei der Mittelsteg zum freien Ende hin, welches der Seitenwand der Stromschiene abgewandt ist, an der die Tragschiene fixiert ist, etwa U-förmig gegabelt ist und in die Gabelung der fünfte oder sechste Leiter eingesetzt ist, so dass er an der Basis der Gabelung anliegt und die Gabelschenkel um ein zur Vermeidung von Kriechspannungen zu den Phasenleitern oder dem Nullleiter ausreichendes Maß über den fünften oder sechsten Leiter vorragen.To provide an arrangement in which Kriechspannungen between the phase conductors, the neutral and the fifth and sixth conductors are excluded, it is provided that each support rail made of insulating material by a first side bar, a central web and a second side bar limited chamber for receiving one each Phase conductor and / or neutral conductor, wherein the central web towards the free end, which faces away from the side wall of the busbar on which the support rail is fixed, is approximately U-shaped forked and inserted into the bifurcation of the fifth or sixth conductor, so that it rests against the base of the bifurcation and the fork legs at a sufficient to avoid creep voltages to the phase conductors or neutral Protrude beyond the fifth or sixth ladder.

Durch diese Ausgestaltung wird sichergestellt, dass Kriechspannungen ausgeschlossen werden können. Des Weiteren kann zur Verbesserung dieses Verhaltens noch vorgesehen sein, dass der Mittelsteg in seinem Bereich zwischen seiner Basis und den die Phasenleiter oder den Nullleiter haltenden Isolierklauen zur Bildung einer verlängerten Kriechstrecke verjüngt ist.This embodiment ensures that creeping stresses can be excluded. Furthermore, in order to improve this behavior, provision may still be made for the center bar to be tapered in its region between its base and the insulating claws holding the phase conductors or the neutral to form an extended creepage distance.

Zudem ist bevorzugt in an sich bekannter Weise vorgesehen, dass zwischen der Tragschiene aus Isolierstoff und der diese haltenden Seitenwand zumindest im Bereich der Anordnung der Phasenleiter oder des Nullleiters ein Luftspalt gebildet ist.In addition, it is preferably provided in a manner known per se that an air gap is formed between the support rail of insulating material and the side wall holding it, at least in the region of the arrangement of the phase conductor or the neutral conductor.

Bevorzugt ist zudem vorgesehen, dass die Tragschienen jeweils in einer parallel zu der Seitenwand der Stromschiene liegenden Ebene die beiden Phasenleiter oder einen Phasenleiter und den Nullleiter halten und dass der fünfte oder sechste Leiter in einer gegenüber dieser Ebene zum Innenraum der Stromschiene verlagerten Ebene liegt.In addition, it is preferably provided that the mounting rails each hold the two phase conductors or a phase conductor and the neutral conductor in a plane lying parallel to the side wall of the busbar, and that the fifth or sixth conductor lies in a plane displaced from the plane to the interior of the busbar.

Auch ist bevorzugt vorgesehen, dass die freien Enden der ersten und zweiten Seitenstege und die Enden der Gabelschenkel des Mittelsteges in einer parallel zur Seitenwand der Stromschiene verlaufenden Ebene liegen.It is also preferably provided that the free ends of the first and second side webs and the ends of the fork legs of the central web lie in a direction parallel to the side wall of the busbar extending plane.

Des Weiteren ist vorgesehen, dass die Phasenleiter der Nullleiter und der fünfte und sechste Leiter gegen manuelle Berührung geschützt in den Tragschienen zurückverlagert angeordnet sind.Furthermore, it is provided that the phase conductors of the neutral and the fifth and sixth conductors are protected against manual contact in the mounting rails shifted back.

Eine Besonderheit wird noch darin gesehen, dass in die Stromschiene endseitig ein Kupplungsstück als Verbinder, Einspeisung oder Endstück eingesteckt ist, das aus Isolierstoff besteht und mit den Phasenleiter, dem Nullleiter, dem fünften und sechsten Leiter sowie mit einem Schutzkontakt in Kontakt stehende Anschlussleiter aufweist, wobei Bestandteile des Kupplungsstückes aus Isolierstoff in Hohlkammern der Stromschiene eingreifen, die zwischen der Tragschiene und den Seitenwänden der Stromschiene gebildet sind, sowie in einen Kammerraum der zwischen einem Tragsteg des fünften oder sechsten Leiters und dem diesem benachbarten Isoliersteg, der den dem Tragsteg benachbarten Bereich jedes Phasenleiters oder des Nullleiters hält, ausgebildet ist.A special feature is seen in the fact that in the busbar end a coupling piece is inserted as a connector, feed or tail, which consists of insulating material and with the phase conductor, the neutral conductor, the fifth and sixth conductor and having a protective contact in contact terminal conductor, wherein components of the coupling piece of insulating material in hollow chambers of the busbar, which are formed between the support rail and the side walls of the busbar, as well as in a chamber space between a support web of the fifth or sixth conductor and the adjacent insulating web, the adjacent the support web area each Phase conductor or the neutral conductor holds, is formed.

Durch die erfindungsgemäß ausgebildete Stromschiene wird eine Stromschiene zur Verfügung gestellt, die sowohl an das Drei-Phasen-Netz anschließbar ist als auch die Anschlüsse an Signalübertragung und dergleichen ermöglicht. Bei einem üblichen angenommenen Aufbau der Stromschiene können beispielsweise über die Phasenleiter 3 x 16 Ampere bei Drehstrombetrieb angeschlossen werden. Über den fünften und sechsten Leiter kann beispielsweise zusätzlich eine Belastung mit 10 Ampere für zusätzliche Leiter erfolgen, oder es können alternativ diese auch für die Signalübertragung oder andere Installationen verwendet werden. Die Luft- und Kriechstrecken sind hierbei eingehalten.The bus bar designed according to the invention provides a bus bar which can be connected both to the three-phase network and also allows the connections to signal transmission and the like. In a conventional assumed structure of the busbar, for example, 3 x 16 amps can be connected in three-phase operation via the phase conductors. Over the fifth and sixth conductor, for example, in addition to a load of 10 amps for additional Conducted or alternatively they can also be used for signal transmission or other installations. The clearances and creepage distances are maintained.

Ein Ausführungsbeispiel einer Stromschiene ist in der einzigen Zeichnungsfigur gezeigt, die eine Stromschiene in einer stirnseitigen Ansicht zeigt.An embodiment of a bus bar is shown in the single drawing figure, which shows a bus bar in a frontal view.

Hierbei ist eine Stromschiene 1 aus Metall vorgesehen, die einen im Wesentlichen U-förmigen Querschnitt hat. Durch die seitlichen zueinander parallelen Seitenwände der Stromschiene ist ein Aufnahmekanal 2 seitlich begrenzt, der kopfseitig durch die Basis der Stromschiene 1 begrenzt ist. An den Seitenwänden der Stromschiene 1 sind Tragschienen 3 aus Isolierstoff angeordnet und mittels verformbarer Stege 4 fixiert. Diese Tragschienen 3 nehmen jeweils mehrere voneinander isolierte, in Schienenlängsrichtung parallel zueinander und einander gegenüberliegende vom Aufnahmekanal 2 her zugängliche, nicht isolierte blanke elektrische Leiter 5,6,7,8 auf. Von diesen sind drei als Phasenleiter geschaltet, beispielsweise die Leiter 5,6,7. Einer dieser Leiter ist als Nullleiter geschaltet, beispielsweise der Leiter 8. Zudem ist im Ausführungsbeispiel an der Basis der Stromschiene 1 ein ebenfalls vom Aufnahmekanal 2 her zugänglicher Schutzleiter 9 ausgebildet oder vorgesehen.Here, a bus bar 1 is provided of metal, which has a substantially U-shaped cross-section. By the side parallel to each other side walls of the busbar, a receiving channel 2 is laterally limited, which is bounded on the head side by the base of the busbar 1. On the side walls of the busbar 1 support rails 3 are arranged made of insulating material and fixed by means of deformable webs 4. These support rails 3 each take a plurality of insulated, in the rail longitudinal direction parallel to each other and opposite from the receiving channel 2 ago accessible, non-insulated bare electrical conductors 5,6,7,8. Of these, three are connected as phase conductors, for example, the conductors 5,6,7. One of these conductors is connected as neutral, for example, the conductor 8. In addition, in the embodiment at the base of the busbar 1, a likewise accessible from the receiving channel 2 ago protective conductor 9 is formed or provided.

Zwischen jeweils einem Leiterpaar 5,6 beziehungsweise 7,8, welches in einer Tragschiene 3 gehalten ist, ist ein fünfter Leiter 10 und ein sechster Leiter 11 isoliert von den Leitern 5,6 beziehungsweise 7,8 des Leiterpaares angeordnet. Der fünfte und sechste Leiter 10,11 liegen einander gegenüber. Beide Leiter sind wiederum vom Aufnahmekanal 2 her zugänglich. Dieser fünfte und sechste Leiter 10,11 kann beispielsweise als Steuerleiter für elektrische oder elektronische Steuerungen geschaltet sein oder auch als zusätzlicher Versorgungsleiter für weitere elektrische Verbraucher an eine Spannungsquelle angeschlossen sein.Between a respective pair of conductors 5, 6 or 7, 8, which is held in a mounting rail 3, a fifth conductor 10 and a sixth conductor 11 are arranged in isolation from the conductors 5, 6 or 7, 8 of the conductor pair. The fifth and sixth ladder 10,11 are opposite each other. Both conductors are in turn accessible from the receiving channel 2 ago. This fifth and sixth conductor 10,11 may for example be connected as a control conductor for electrical or electronic controls or be connected as an additional supply conductor for other electrical loads to a voltage source.

An dem der Basis der Stromschiene 1 abgewandten Endbereich der Seitenwände sind Auflagebereiche 12,13 für einen in die Stromschiene 1 eingesetzten Adapter ausgebildet. Im Ausführungsbeispiel ist einer dieser Auflagebereiche, nämlich der Auflagebereich 13 mit einem zusätzlichen blanken Schutzleiter 14 ausgestattet, der vom Aufnahmekanal 2 her zugänglich ist.At the end of the side walls facing away from the base of the busbar 1 bearing areas 12,13 are formed for a used in the busbar 1 adapter. In the exemplary embodiment, one of these support areas, namely the support area 13 is provided with an additional bare protective conductor 14, which is accessible from the receiving channel 2 ago.

Jede Tragschiene 3 aus Isolierstoff weist eine durch einen ersten Seitensteg 15, einen Mittelsteg 16 und einen zweiten Seitensteg 17 begrenzte Kammer zur Aufnahme jeweils eines Phasenleiters oder Nullleiters 5,6,7,8 auf. Der Mittelsteg 16 ist zu seinem freien Ende hin, welches der Seitenwand der Tragschiene 1 abgewandt ist, an welcher die Tragschiene 3 fixiert ist, etwa U-förmig gegabelt, wobei in die Gabelung der fünfte oder sechste Leiter 10,11 eingesetzt ist, so dass der jeweilige Leiter an der Basis der Gabelung anliegt und die Gabelschenkel 22 um ein solches Maß über den fünften oder sechsten Leiter 10,11 vorragen, dass Kriechspannungen zwischen den Leitern 5,6 und 10 beziehungsweise 7,8 und 11 vermieden sind.Each support rail 3 of insulating material has a limited by a first side web 15, a central web 16 and a second side web 17 chamber for receiving in each case a phase conductor or neutral conductor 5,6,7,8. The central web 16 is towards its free end, which faces away from the side wall of the support rail 1, on which the support rail 3 is fixed, approximately U-shaped forked, wherein in the bifurcation of the fifth or sixth ladder 10,11 is inserted, so that the respective conductor rests against the base of the fork and the fork legs 22 protrude by such a degree on the fifth or sixth conductor 10,11 that creep between the conductors 5, 6 and 10 or 7, 8 and 11 are avoided.

Der Mittelsteg 16 ist in seinem Bereich zwischen der Basis 18 und den die Phasenleiter 5,6 beziehungsweise 7 oder den Nullleiter 8 haltenden Isolierklauen 19 ebenfalls zur Bildung einer verlängerten Kriechstrecke verjüngt.The central web 16 is also tapered in its region between the base 18 and the insulating claws 19 holding the phase conductors 5, 6 and 7 or the neutral conductor 8, respectively, to form an extended creeping distance.

Zwischen der Tragschiene 3 aus Isolierstoff und der diesen haltenden Seitenwand der Stromschiene 1 ist jeweils im Bereich der Anordnung der Phasenleiter 5,6,7 beziehungsweise des Nullleiters 8 ein Luftspalt gebildet. Diese den Luftspalt umgrenzende Kammer ist mit 20 bezeichnet.Between the support rail 3 made of insulating material and the side wall of the busbar 1 holding this, an air gap is formed in each case in the region of the arrangement of the phase conductors 5, 6, 7 or of the neutral conductor 8. This air gap defining chamber is designated 20.

Wie aus der Zeichnung ersichtlich, halten die Tragschienen 3 jeweils in einer parallel zu der entsprechenden Seitenwand der Stromschiene 1 liegenden Ebene die beiden Phasenleiter 5,6 beziehungsweise den Phasenleiter 7 und den Nullleiter 8. Der fünfte Leiter 10 und der sechste Leiter 11 sind jeweils in einer gegenüber dieser Ebene zum Innenraum der Stromschiene 1 hin verlagerten Ebene angeordnet. Auch diese Ausgestaltung dient dazu einerseits die zusätzlichen fünften und sechsten Leiter 10,11 innerhalb der Stromschiene 1 anordnen zu können und andererseits dazu, einen ausreichenden Abstand der Leiter voneinander zu gewährleisten, um Kriechströme zu vermeiden.As can be seen from the drawing, hold the support rails 3 each in a plane parallel to the corresponding side wall of the busbar 1 level, the two phase conductors 5.6 and the phase conductor 7 and the neutral conductor 8. The fifth conductor 10 and the sixth conductor 11 are respectively in arranged opposite to this level to the interior of the busbar 1 toward shifted level. This embodiment also serves on the one hand the additional fifth and sixth conductors 10,11 be able to arrange within the busbar 1 and on the other hand, to ensure a sufficient distance of the conductors from each other to avoid leakage currents.

Die freien Enden der ersten und zweiten Seitenstege 15,17 und die Enden der Gabelschenkel 22 des Mittelsteges 16 liegen jeweils in einer parallel zur entsprechenden Seitenwand der Stromschiene 1 verlaufenden Ebene.The free ends of the first and second side webs 15,17 and the ends of the fork legs 22 of the central web 16 are each in a direction parallel to the corresponding side wall of the busbar 1 extending plane.

Alle Leiter, das heißt, die Phasenleiter 5 bis 7, der Nullleiter 8 und der fünfte und sechste Leiter 10,11 sind gegen manuelle Berührung geschützt, in dem sie in den Tragschienen 3 zurückverlagert angeordnet sind.All conductors, that is, the phase conductors 5 to 7, the neutral conductor 8 and the fifth and sixth conductors 10,11 are protected against manual contact, in which they are arranged shifted back in the support rails 3.

In der Zeichnung nicht gezeigt, ist ein Kupplungsstück oder dergleichen, welches endseitig in die Stromschiene 1 als Verbinder, Einspeisung oder Endstück eingesteckt wird. Ein solches Kupplungsstück besteht aus Isolierstoff und ist mit Phasenleitern, dem Nullleiter, dem fünften und sechsten Leiter sowie mit einem Schutzkontakt der Stromschiene 1 kontaktiert, wenn es in die Stromschiene eingesetzt ist.Not shown in the drawing, is a coupling piece or the like, which is inserted end in the busbar 1 as a connector, feed or tail. Such a coupling piece is made of insulating material and is contacted with phase conductors, the neutral conductor, the fifth and sixth conductors and with a protective contact of the busbar 1 when it is inserted into the busbar.

In dieser Montagesolllage greifen Bestandteile des Kupplungsstückes aus Isolierstoff in die Hohlkammern 20 der Stromschiene 1 ein, die zwischen der Tragschiene 3 und den Seitenwänden der Stromschiene 1 gebildet sind sowie in einem Kammerraum 21, der zwischen dem Tragsteg für den fünften Leiter 10 beziehungsweise den sechsten Leiter 11 und dem diesen benachbarten Isoliersteg 19, der den dem Tragsteg benachbarten Bereich des Phasenleiters 5,6,7 oder des Nullleiters 8 hält, ausgebildet. Durch diese Anordnung wird erreicht, dass die Luftstrecke an der Trennfuge zwischen dem Ende der Stromschiene 1 und dem in diese eingesetzten Kupplungsstück hinsichtlich der Luftstrecke zwischen den Kontakten verlängert ist, so dass eine hohe Betriebssicherheit gewährleistet ist.In this assembly target position components of the coupling piece of insulating material engage in the hollow chambers 20 of the busbar 1, which are formed between the support rail 3 and the side walls of the busbar 1 and in a chamber space 21, between the support web for the fifth conductor 10 and the sixth Ladder 11 and the insulating strip 19 adjacent thereto, which holds the portion of the phase conductor 5,6,7 or the neutral conductor 8 adjacent to the support web.
