Abstract

The production and assembly of a multi-pole high-voltage switching apparatus is simplified in that the supporting rail (1) for the pole columns (7) is produced from an integral metal sheet by bending over. The openings for the pole columns on the top of the supporting rail are incorporated before the bending over. (The supporting rail is a bent-over sheet-metal profile). <IMAGE>

Description

Die Erfindung bezieht sich auf einen mehrpoligen elektrischen Leistungsschalter gemäß Oberbegriff des Anspruchs 1.The invention relates to a multi-pole electrical circuit breaker according to the preamble of claim 1.

Ein solcher Leistungsschalter ist beispielsweise aus der DE-A-20 17 836 bekannt. Über die technische Ausführung der Tragschiene für die erforderliche Steifheit ist dort nichts gesagt.Such a circuit breaker is known for example from DE-A-20 17 836. Nothing is said there about the technical design of the mounting rail for the required rigidity.

Aus der DE-OS-29 13 379 ist es bekannt, eine rohrförmige Tragschiene für ein mehrpoliges Schaltgerät zu verwenden. Eine solche rohrförmige Tragschiene ist einerseits im Bereich ihres Innenraumes schwer zugänglich, andererseits sind die Polsäulen nur durch zusätzlichen Aufwand zuverlässig und tragfähig mit der rohrförmigen Tragschiene zu verbinden.From DE-OS-29 13 379 it is known to use a tubular mounting rail for a multi-pole switching device. Such a tubular mounting rail is difficult to access on the one hand in the area of its interior, on the other hand, the pole columns can only be connected to the tubular mounting rail reliably and in a load-bearing manner by additional effort.

Aus der DE-U 90 170 55 ist ein Traggestell für Hochspannungsschalter bekannt, das aus mehreren gebogenen Blechprofilen besteht, die mittels Schraubverbindungen zu einem Tragprofil verbunden und durch zusätzliche Versteifungsbleche verstärkt sind.From DE-U 90 170 55 a support frame for high-voltage switches is known, which consists of several bent sheet metal profiles, which are connected by means of screw connections to form a support profile and are reinforced by additional stiffening plates.

Aus der DE-C-68 20 30 ist eine U-förmige Schiene aus Blech bekannt, die eine Längsfuge zur magnetischen Isolation aufweist und durch ein weiteres Blech und gegebenenfalls Beton verstärkt ist.From DE-C-68 20 30 a U-shaped rail made of sheet metal is known, which has a longitudinal joint for magnetic insulation and is reinforced by another sheet and possibly concrete.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen mehrpoligen elektrischen Leistungsschalter mit einer Tragschiene auszustatten, die einfach und wirtschaftlich herstellbar ist und auf der die Polsäulen einfach und sicher befestigt werden können. Die Polsäulen sollen außerdem im Bereich der Tragschiene gut zugänglich sein.In contrast, the present invention seeks to provide a multi-pole electrical circuit breaker to equip a mounting rail that is simple and economical to manufacture and on which the pole columns can be easily and securely attached. The pole columns should also be easily accessible in the area of the mounting rail.

Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.

Die Tragschiene ist aus einem ebenen Blech auf einer bekannten Abkantvorrichtung schnell, einfach und präzise herzustellen. Die Öffnungen für Schraubenbefestigungen und für die Polsäulen können vor dem Abkanten in das Blech eingebracht werden, beispielsweise durch Stanzen oder Plasmaschneiden.The mounting rail can be manufactured quickly, easily and precisely from a flat sheet metal on a known folding device. The openings for screw fastenings and for the pole columns can be made in the sheet before folding, for example by punching or plasma cutting.

Es ist keine Montage der einzelnen Tragschienen mehr notwendig. Außerdem wird die Tragschiene durch das Fehlen von Verstärkungen für die Befestigungen sehr leicht.It is no longer necessary to assemble the individual mounting rails. In addition, the lack of reinforcements for the fastenings makes the mounting rail very light.

Die Herstellung der Tragschiene wird durch den einfachen Arbeitsgang des Abkantens sehr kostengünstig.The manufacture of the mounting rail is very cost-effective due to the simple folding process.

An der den Stützisolatoren zugewandten Seite der Tragschiene können vorteilhaft Traglager für die Polsäulen angeordnet sein.Support bearings for the pole columns can advantageously be arranged on the side of the support rail facing the support insulators.

Die Polsäulen sind, auch wenn sie auf die Tragschiene montiert sind, von oben und unten her für Montagezwecke leicht zugänglich. Durch die offene Profilform der Tragschiene ist auch der Bereich der Polsäulen unterhalb der Tragschiene leicht zugänglich.The pole columns, even if they are mounted on the mounting rail, are easily accessible from above and below for installation purposes. Due to the open profile shape of the mounting rail, the area of the pole columns below the mounting rail is easily accessible.

Die Verbindung des die Tragschiene durchsetzenden Teils der Polsäulen mit den freien Enden der Schenkel der Tragschiene kann durch Verschrauben oder eine Schweißverbindung realisiert sein. Es kann sich als vorteilhaft erweisen, den Teil der Polsäule über stabile metallische Stege oder Bleche mit den freien Enden der Schenkel der Tragschiene zu verbinden. Besonders stabil wird die Verbindung bei einer direkten Verschraubung der freien Enden der Schenkel der Tragschiene mit der Polsäule.The connection of the part passing through the mounting rail the pole columns with the free ends of the legs of the mounting rail can be realized by screwing or a welded connection. It can prove to be advantageous to connect the part of the pole column to the free ends of the legs of the mounting rail by means of stable metallic webs or sheets. The connection becomes particularly stable when the free ends of the legs of the mounting rail are screwed directly to the pole column.

Im folgenden sei die Erfindung anhand eines Ausführungsbeispiels in einer Zeichnung gezeigt und anschließend beschrieben.

Figur 1
zeigt ein erfindungsgemäßes Schaltgerät mit einer Tragschiene im Querschnitt,
Figur 2
eine Tragschiene in perspektivischer Ansicht.
In the following, the invention is shown on the basis of an exemplary embodiment in a drawing and then described.
Figure 1
shows a switching device according to the invention with a mounting rail in cross section,
Figure 2
a mounting rail in a perspective view.

Die Tragschiene 1 weist zwei freie Schenkel 2, 3 auf, die nach dem Abkanten des Bleches von der den Stützisolatoren zugewandten Seite 4 der Tragschiene 1 rechtwinklig abstehen und mit ihren freien Enden 5, 6 nach der den Stützisolatoren 13 abgewandten Seite weisen. Die freien Enden 5, 6 sind, abermals durch Abkanten, nach innen umgebogen.The mounting rail 1 has two free legs 2, 3 which, after the sheet metal has been bent, protrude at right angles from the side 4 of the mounting rail 1 facing the support insulators and point with their free ends 5, 6 to the side facing away from the support insulators 13. The free ends 5, 6 are bent inwards again by folding.

Die Tragschiene 1 bildet somit einen Kanal zur Aufnahme derjenigen Teile der Polsäulen 7, die durch Öffnungen 8, 9, 10 an der den Stützisolatoren 13 zugewandten Seite 4 der Tragschiene 1 hindurchragen. Die freien, umgebogenen Enden 5, 6 der Schenkel 2, 3 der Tragschiene 1 sind über Bleche 11, 12 mit den Polsäulen 7 verbunden. Dadurch wird eine größere Steifigkeit der Tragschiene 1 gegen Verwindung und Verbiegung erreicht.The support rail 1 thus forms a channel for receiving those parts of the pole columns 7 which protrude through openings 8, 9, 10 on the side 4 of the support rail 1 facing the support insulators 13. The free, bent ends 5, 6 of the legs 2, 3 of the mounting rail 1 are connected to the pole columns 7 via plates 11, 12. This results in greater rigidity of the mounting rail 1 against twisting and bending.

Die Polsäulen 7 sind an der den Stützisolatoren 13 zugewandten Seite 4 der Tragschiene 1 durch Schrauben befestigt. Die Löcher für die Schrauben sind in dem Blech der Tragschiene 1 schon vor dem Abkanten vorhanden und werden entweder durch Stanzen, Plasmaschneiden, Fräsen oder Bohren eingebracht, ebenso wie die Öffnungen für die Polsäulen 7.The pole columns 7 are fastened to the side 4 of the mounting rail 1 facing the support insulators 13 by screws. The holes for the screws are already in the sheet metal of the mounting rail 1 before they are folded and are introduced either by punching, plasma cutting, milling or drilling, as are the openings for the pole columns 7.

Die freien Enden 5, 6 der Schenkel 2, 3 der Tragschiene 1 können für sich so lang ausgebildet sein, daß sie direkt und ohne Verbindungsbleche 11, 12 über Schraubverbindungen mit den Polsäulen 7 verbunden werden können. das erleichtert die Montage des Schaltgerätes.The free ends 5, 6 of the legs 2, 3 of the mounting rail 1 can be of such a length that they can be connected directly and without connecting plates 11, 12 to the pole columns 7 via screw connections. this facilitates the assembly of the switchgear.

Die typische Blechdicke für die Tragschiene 1 beträgt etwa 6 bis 8 mm. Es sind in den Schenkeln 2, 3 der Tragschiene 1 Eingriffsöffnungen 15, 16,17 vorgesehen, durch die die Polsäulen 7 von außen im Bereich der Tragschiene leicht zugänglich sind.The typical sheet thickness for the mounting rail 1 is approximately 6 to 8 mm. There are engagement openings 15, 16, 17 in the legs 2, 3 of the mounting rail 1, through which the pole columns 7 are easily accessible from the outside in the area of the mounting rail.
