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 Phasenleiter und einen Nullleiter aufnehmen, wobei zudem vorzugsweise an der Basis der Stromschiene ein ebenfalls vom Aufnahmekanal zugänglicher Schutzleiter vorgesehen ist, wobei zwischen jeweils einem Leiterpaar, welches in einer Tragschiene gehalten ist, ein fünfter und sechster blanker Steuerleiter isoliert von den Phasenleitern und dem Nullleiter des Leiterpaares angeordnet ist, wobei der fünfte und sechste Steuerleiter einander gegenüber liegen und vom Aufnahmekanal her zugänglich sind, wobei der fünfte und sechste Steuerleiter zum Anschluss für eine elektrische oder elektronische Steuerung oder als zusätzliche Versorgungsleiter für weitere elektrische Verbraucher bestimmt sind oder an diese angeschlossen sind.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 phase conductors and a neutral conductor, wherein also preferably at the base of the busbar a likewise accessible from the receiving channel protective conductor is provided, wherein between each pair of conductors, which is held in a support rail, a fifth and sixth bare control conductor isolated is arranged by the phase conductors and the neutral conductor of the conductor pair, wherein the fifth and sixth control conductors are opposite to each other and are accessible from the receiving channel, wherein the fifth and sixth control conductor to the terminal f ÜR an electrical or electronic control or as additional supply conductor for other electrical consumers are intended or connected to this.

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.

Eine gattungsgemäße Stromschiene ist aus der EP 0 015 356 A1 bekannt. Bei dieser sind in jedem Schenkel der Stromschiene zwei Phasenleiter und ein Nullleiter vorgesehen, die alternativ durch einen in die Schiene eingesetzten Adapter kontaktierbar sind. Steuerleiter sind hierbei nicht vorgesehen.A generic busbar is from the EP 0 015 356 A1 known. In this two phase conductors and a neutral conductor are provided in each leg of the busbar, which can alternatively be contacted by an adapter used in the rail. Control conductors are not provided here.

Aus der DE 100 18 680 A1 ist eine ähnliche Ausgestaltung ersichtlich, bei der in einem Schenkel der Stromschiene zwei Phasenleiter, in dem anderen Schenkel ein Phasenleiter und ein Nullleiter und in beiden Schenkeln je ein Signalleiter vorgesehen, wobei zwischen jeweils einem Phasenleiter und einem Signalleiter eine Zwischenwand aus elektrisch leitfähigem Material angeordnet ist.From the DE 100 18 680 A1 a similar embodiment can be seen in which in one leg of the busbar two phase conductors, in the other leg a phase conductor and a neutral conductor and provided in both legs each have a signal conductor, wherein between each a phase conductor and a signal conductor an intermediate wall made of electrically conductive material is arranged ,

Aus der EP 0 465 098 A1 ist eine ähnliche Ausgestaltung wie aus der EP 0 015 356 A1 bekannt.From the EP 0 465 098 A1 is a similar embodiment as from the EP 0 015 356 A1 known.

Aus der FR 2 178 914 A1 ist eine Stromschiene bekannt, bei der an einem Schenkel mündungsnah ein Schutzleiter angeordnet ist.From the FR 2 178 914 A1 a busbar is known in which a protective earth conductor is arranged on a leg close to the mouth.

Aus der US 4 919 625 A ist eine vierpolige Stromschiene bekannt, bei der ein Leiter etwas näher zur Mitte der Schiene versetzt ist.From the US 4,919,625 A a four-pole busbar is known in which a conductor is slightly closer to the center of the rail.

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, wobei zudem Kriechspannungen zwischen den Phasenleitern, dem Nullleiter und dem fünften und sechsten Steuerleiter ausgeschlossen werden sollen.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, which also creep voltages between the phase conductors, the neutral and the fifth and sixth control conductor should be excluded.

Diese Aufgabe wird von einer Stromschiene mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a busbar with the features of claim 1.

Zur Lösung der Aufgabe wird vorgeschlagen, jede Tragschiene aus Isolierstoff Kammern zur Aufnahme jeweils eines Phasenleiters und/oder eines Nullleiters aufweist, wobei eine erste Kammer durch einen ersten Seitensteg und einen Mittelsteg begrenzt ist, und eine zweite Kammer durch den Mittelsteg und einen zweiten Seitensteg begrenzt ist, und dass der Mittelsteg zu seinem freien Ende hin, welches der Seitenwand der Stromschiene abgewandt ist, an der die Tragschiene fixiert ist, etwa U-förmig gegabelt ist und die Gabelung der fünfte oder sechste Steuerleiter eingesetzt ist, so dass er an der Basis der Gabelung anliegt.To achieve the object, it is proposed to have each support rail of insulating chambers for receiving in each case a phase conductor and / or a neutral conductor, wherein a first chamber is bounded by a first side web and a central web, and a second chamber bounded by the central web and a second web side is, and that the central web towards its 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 the bifurcation of the fifth or sixth control conductor is inserted, so that it at the base the bifurcation is applied.

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.

Zudem wird durch diese Ausgestaltung sichergestellt, dass Kriechspannungen ausgeschlossen werden können.In addition, this design ensures that creep voltages can be excluded.

Bevorzugt ist vorgesehen, dass die Gabelschenkel der Gabelung um ein zur Vermeidung von Kriechspannungen zu den Phasenleitern oder dem Nullleiter ausreichendes Maß über den fünften oder sechsten Steuerleiter vorragen.It is preferably provided that the fork legs of the fork protrude by a measure sufficient to avoid Kriechspannungen to the phase conductors or the neutral level on the fifth or sixth control conductor.

In an sich bekannter Weise kann dabei vorgesehen sein, dass in die Stromschiene ein Adapter zur Kontaktierung mit den Phasenleitern, dem Nullleiter und den Steuerleitern eingesetzt ist, und dass an dem der Basis der Stromschiene abgewandten Endbereich der Seitenwände Auflagebereiche für den in die Stromschiene eingesetzten Adapter ausgebildet sind, wobei vorzugsweise einer dieser Auflagebereiche einen blanken Schutzleiter hält, der vom Aufnahmekanal her zugänglich ist.In known manner, it may be provided that in the busbar, an adapter for contacting with the phase conductors, the neutral conductor and the control conductors is used, and that at the base of the busbar remote end portion of the side walls bearing areas for the adapter used in the busbar are formed, preferably one of these bearing 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.

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.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.
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 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.
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 Steuerleiter 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 control conductors are arranged 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 Phasenleitern, dem Nullleiter, dem fünften und sechsten Steuerleiter 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 Steuerleiters und dem diesem benachbarten Isoliersteg, der den dem Tragsteg benachbarten Bereich jedes Phasenleiters oder des Nullleiters hält, ausgebildet ist.A special feature is still seen in that in the busbar end a coupling piece is inserted as a connector, feed or tail, which consists of insulating material and having the phase conductors, the neutral conductor, the fifth and sixth control conductor and standing with 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 control 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 Steuerleiter kann beispielsweise zusätzlich eine Belastung mit 10 Ampere für zusätzlicheThe 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, via the phase conductors 3 x 16 amps in three-phase operation be connected. Over the fifth and sixth control conductor, for example, in addition to a load of 10 amps for additional

Die Luft- und Kriechstrecken sind hierbei eingehalten.Conducted or alternatively they can also be used for signal transmission or other installations. The clearances and creepage distances are maintained.

These mounting rails 3 each take a plurality of mutually insulated, in the rail longitudinal direction parallel to each other and opposite from the receiving channel 2 ago accessible, non-insulated bare electrical phase conductors 5,6,7 and a neutral conductor 8. In addition, a likewise accessible from the receiving channel 2 ago protective conductor 9 is formed or provided in the embodiment at the base of the busbar 1.
