Description

Die Erfindung betrifft ein Installationsschaltgerät mit einem Gehäuse, das eine obere Breitseite, eine untere Breitseite, eine Frontseite, eine Befestigungsseite und eine Schmalseite umfasst, und mit einer Lichtbogenlöscheinrichtung, wobei in dem Gehäuse ein Zwischenstück so angeordnet ist, dass die Lichtbogenlöscheinrichtung in einem Teilraum zwischen der oberen Breitseite und dem Zwischenstück aufgenommen ist, und wobei eine parallel zu den Breitseiten verlaufende Abluftwand mit der oberen Breitseite einen ersten Abluftkanal bildet, der den Abgasstrom aus dem der Schmalseite zuweisenden Ende der Lichtbogenlöscheinrichtung zu einer ersten Abluftöffnung in der Schmalseitenwand des Gehäuses leitet, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an installation switching device having a housing which comprises an upper broad side, a lower broad side, a front side, a fastening side and a narrow side, and with an arc quenching device, wherein in the housing an intermediate piece is arranged so that the arc quenching device in a subspace between the upper broad side and the intermediate piece is received, and wherein a parallel to the broad sides extending exhaust air wall with the upper broad side forms a first exhaust duct, which directs the exhaust gas flow from the narrow side facing the end of the arc quenching device to a first exhaust port in the narrow side wall of the housing, according to the preamble of claim 1.

Ein solches Installationsschaltgerät ist beispielsweise ein selektiver Hauptleitungsschutzschalter, wie er aus der DE 10 2008 017 472 A1 bekannt ist. Die Offenbarung der DE 10 2008 017 472 A1 soll bezüglich des Aufbaus und der Funktionsweise eines selektiven Hauptleitungsschutzschalters in den Offenbarungsgehalt der vorliegenden Erfindung mit einbezogen sein.Such a service switching device is, for example, a selective main line circuit breaker, as it is known from DE 10 2008 017 472 A1 is known. The revelation of DE 10 2008 017 472 A1 It is intended to be incorporated into the disclosure of the present invention for the construction and operation of a selective main circuit breaker.

Der Abgasstrom aus der Lichtbogenlöscheinrichtung wird bei dem Installationsschaltgerät, wie es in der DE 10 2008 017 472 A1 beschrieben ist, über einen Abgaskanal, der zwischen der Abluftwand des Zwischenstücks und der oberen Breitseite des Gehäuses verläuft, und der durch Rippen auf der Abluftwand in parallel zueinander verlaufende Teilkanäle unterteilt ist, zu einer Reihe von Abluftöffnungen in der Schmalseite des Gehäuses geführt.The exhaust gas flow from the arc quenching device is in the service switching device, as shown in the DE 10 2008 017 472 A1 is described, via an exhaust passage which extends between the exhaust wall of the intermediate piece and the upper broad side of the housing, and which is divided by ribs on the exhaust air wall in parallel sub-channels, led to a series of exhaust ports in the narrow side of the housing.

Es ist die Aufgabe der vorliegenden Erfindung, ein gattungsgemäßes Installationsschaltgerät so weiterzuentwickeln, dass die Abluftführung verbessert ist, so dass auch hohe Schaltleistungen bei kompaktem Aufbau erreicht werden können.It is the object of the present invention to develop a generic service switching device so that the exhaust air duct is improved, so that even high switching capacities can be achieved in a compact design.

Die Aufgabe wird gelöst durch ein gattungsgemäßes Installationsschaltgerät mit den kennzeichnenden Merkmalen des Anspruchs 1.The object is achieved by a generic service switching device with the characterizing features of claim 1.

Erfindungsgemäß also ist an der Schmalseite zwischen der Abluftwand des Zwischenstücks und der unteren Breitseite ein Klemmenisolierteil angeordnet, mit einer Klemmraumtrennwand, und in der Abluftwand des Zwischenstücks ist eine Zwischenöffnung vorhanden, die mit einer Isolierteilöffnung in dem Klemmenisolierteil fluchtet, so dass ein zweiter Abluftkanal gebildet ist, der einen ersten Teilstrom der Abgase von der Zwischenöffnung ausgehend zwischen der Klemmraumtrennwand und der unteren Breitseite zu einer zweiten Abluftöffnung in der Schmalseitenwand führt.According to the invention, a terminal insulating part is arranged on the narrow side between the exhaust air wall of the intermediate piece and the lower broad side, with a terminal space partition, and in the exhaust air wall of the intermediate piece there is an intermediate opening which is aligned with a Isolierteilöffnung in the terminal insulating, so that a second exhaust duct is formed which leads a first partial flow of the exhaust gases starting from the intermediate opening between the terminal space partition wall and the lower broad side to a second exhaust opening in the narrow side wall.

Der Einsatz des erfindungsgemäßen Klemmenisolierteils ermöglicht in vorteilhafter Weise, dass ein zusätzlicher, zweiter Abgaskanal entstehen kann, so dass neben dem Abgasstrom ein erster Teilstrom an einer anderen Stelle aus dem Gerät herausgeführt werden kann. Es sind erfindungsgemäß nun in zwei Bereichen der Schmalseitenwand Austrittsöffnungen für die abgase vorhanden. Damit kann eine größere Menge Abgas ausströmen, der Druck im Bereich der Lichtbogenlöscheinrichtung kann schneller abgebaut werden, und das Gehäuseinnere wird weniger durch Ablagerungen aus den Abgasen verunreinigt. Insgesamt kann daher eine höhere Schaltleistung bei kompaktem Gesamtaufbau erreicht werden.The use of the terminal insulating part according to the invention advantageously makes it possible to form an additional, second exhaust gas channel so that a first partial flow can be led out of the device at a different location in addition to the exhaust gas flow. There are now according to the invention in two areas of the narrow side wall outlet openings for the exhaust gases available. Thus, a larger amount of exhaust gas can flow out, the pressure in the area of the arc quenching device can be degraded faster, and the housing interior is less contaminated by deposits from the exhaust gases. Overall, therefore, a higher switching performance can be achieved with a compact overall design.

Gemäß einer vorteilhaften Ausführungsform der Erfindung bilden die Klemmraumtrennwand des Klemmenisolierteils und die Abluftwand des Zwischenstücks im Bereich der Schmalseitenwand einen zur Schmalseite hin offenen Klemmenraum zur Aufnahme einer Anschlussklemme. Das Klemmenisolierteil bildet also einen Teil des Klemmenaufnahmeraums. Der erste Teilstrom wird also um den Klemmenaufnahmeraum herum geleitet. Die beiden Austrittsstellen für die Abgase befinden sich somit zu beiden Seiten der Anschlussklemme.According to an advantageous embodiment of the invention, the terminal space dividing wall of the terminal insulating part and the exhaust wall of the intermediate piece in the region of the narrow side wall form a terminal space open towards the narrow side for receiving a connection terminal. The terminal insulating part thus forms part of the terminal receiving space. The first partial flow is thus conducted around the terminal receiving space. The two exit points for the exhaust gases are thus on both sides of the terminal.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist die Schmalseitenwand teilweise durch eine erste und zweite Platte gebildet, die an dem Zwischenstück und dem Klemmenisolierteil angeformt sind.According to a further advantageous embodiment of the invention, the narrow side wall is partially formed by a first and second plate, which are integrally formed on the intermediate piece and the terminal insulating part.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung weist die erste Platte eine Ausbuchtung an ihrer der vorderen Breitseite zuweisenden Schmalseite, so dass die erste Abluftöffnung im Bereich der Ausbuchtung zwischen der ersten Platte und der vorderen Breitseite des Gehäuses gebildet ist.According to a further advantageous embodiment of the invention, the first plate has a bulge at its narrow side facing the front broadside, so that the first exhaust opening is formed in the region of the bulge between the first plate and the front broad side of the housing.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung weist die zweite Platte wenigstens eine Ausbuchtung an ihrer der hinteren Breitseite zuweisenden Schmalseite auf, so dass die zweite Abluftöffnung im Bereich der Ausbuchtung zwischen der zweiten Platte und der hinteren Breitseite des Gehäuses gebildet ist.According to a further advantageous embodiment of the invention, the second plate has at least one bulge at its narrow side facing the rear broad side, so that the second exhaust air opening is formed in the region of the bulge between the second plate and the rear broad side of the housing.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist an die Abluftwand ein den ersten Abluftkanal zur Befestigungsseite hin begrenzender Steg angeformt, der eine Stegöffnung trägt, so dass ein zweiter Teilstrom der Abgase durch die Stegöffnung zu der Befestigungsseite und dort durch eine dritte Abluftöffnung nach außen geleitet wird. Somit wird der weitere Vorteil erzielt, dass der Abgasstrom auf insgesamt drei Teilströme aufgeteilt wird, die an drei unterschiedlichen Stellen das Gerät verlassen können, wodurch ein Abbau des Überdrucks im Gerät nach entstandener Kurzschlussstromunterbrechung sehr effektiv erfolgt und die Abgase sehr schnell aus dem Gerät ausgeleitet werden.According to a further advantageous embodiment of the invention, a web which delimits the first exhaust air duct to the fastening side is formed on the exhaust air wall, which carries a web opening, so that a second partial flow of the exhaust gases is conducted through the web opening to the fastening side and there through a third exhaust air opening to the outside , Thus, the further advantage that the exhaust stream is divided into a total of three sub-streams, which can leave the device at three different locations, whereby a reduction of the pressure in the device after resulting short circuit interruption is very effective and the exhaust gases are discharged from the device very quickly ,

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung sind an der Abluftwand des Zwischenstücks Führungsstege angebracht, die die Abgase aus der Lichtbogenlöscheinrichtung auf den Abgasstrom und den ersten und zweiten Teilstrom aufteilen.According to a further advantageous embodiment of the invention guide webs are attached to the exhaust air wall of the intermediate piece, which divide the exhaust gases from the arc quenching device to the exhaust gas flow and the first and second partial flow.

Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments and improvements of the invention and further advantages can be taken from the further subclaims.

Anhand der Zeichnungen, in denen ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläutert und beschrieben werden.Reference to the drawings, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements of the invention will be explained and described in detail.

Figur 1 zeigt in sehr schematischer Darstellung einen Ausschnitt aus einem Installationsschaltgerät 1, die Figuren 2 bis 4 zeigen perspektivische Teil-Ansichten eines ausgeführten Installationsschaltgerätes 1. Das Installationsschaltgerät 1 hat ein Gehäuse 2, das eine obere Breitseite 3, eine untere Breitseite 4, eine Frontseite 7, eine Befestigungsseite 6 und eine Schmalseite 5 umfasst, und mit einer Lichtbogenlöscheinrichtung 8. Die Lichtbogenlöscheinrichtung 8 ist eine Anordnung von übereinander gestapelten Lichtbogenlöschblechen, wie in der Figur 3 am rechten Rand zu erkennen, und im Prinzip bekannt. FIG. 1 shows a very schematic representation of a section of an installation switching device 1, the FIGS. 2 to 4 show perspective part views of a running installation switching device 1. The installation switching device 1 has a housing 2, which comprises an upper broad side 3, a lower broad side 4, a front 7, a mounting side 6 and a narrow side 5, and with an arc quenching device 8. The arc quenching device FIG. 8 is an arrangement of stacked arc quenching plates as shown in FIG FIG. 3 recognizable on the right edge, and known in principle.

In dem Gehäuse 2 ist ein Zwischenstück 9 so angeordnet, dass die Lichtbogenlöscheinrichtung 8 in einem Teilraum 10 zwischen der oberen Breitseite 3 und dem Zwischenstück 9 aufgenommen ist. Eine parallel zu den Breitseiten 3, 4 verlaufende Abluftwand 11 bildet mit der oberen Breitseite 3 einen ersten Abluftkanal 12, der den Abgasstrom 13 aus dem der Schmalseite 5 zuweisenden Ende 14 der Lichtbogenlöscheinrichtung 8 zu einer ersten Abluftöffnung 15 in der Schmalseitenwand 5 des Gehäuses 2 leitet.In the housing 2, an intermediate piece 9 is arranged so that the arc quenching device 8 is received in a subspace 10 between the upper broad side 3 and the intermediate piece 9. A parallel to the broad sides 3, 4 extending exhaust air wall 11 forms with the upper broad side 3, a first exhaust duct 12 which directs the exhaust stream 13 from the narrow side 5 assigning end 14 of the arc quenching device 8 to a first exhaust port 15 in the narrow side wall 5 of the housing 2 ,

An der Schmalseite 5 ist zwischen der Abluftwand 11 des Zwischenstücks 9 und der unteren Breitseite 4 ein Klemmenisolierteil 16 angeordnet. Es hat eine Klemmraumtrennwand 17, und in der Abluftwand 11 des Zwischenstücks 9 ist eine Zwischenöffnung 18 vorhanden, die mit einer Isolierteilöffnung 19 in dem Klemmenisolierteil 16 fluchtet. Dadurch ist ein zweiter Abluftkanal 20 gebildet, der einen ersten Teilstrom 21 der Abgase von der Zwischenöffnung 18 ausgehend zwischen der Klemmraumtrennwand 17 und der unteren Breitseite 4 zu einer zweiten Abluftöffnung 22 in der Schmalseitenwand 5 führt.On the narrow side 5, a terminal insulating part 16 is disposed between the exhaust air wall 11 of the intermediate piece 9 and the lower broad side 4. It has a terminal space partition wall 17, and in the exhaust air wall 11 of the intermediate piece 9 there is an intermediate opening 18, which is aligned with an insulating part opening 19 in the terminal insulating part 16. As a result, a second exhaust air duct 20 is formed, the first partial flow 21 of the exhaust gases from the intermediate opening 18, starting between the terminal space partition wall 17 and the lower broad side 4 leads to a second exhaust port 22 in the narrow side wall 5.

Die Klemmraumtrennwand 17 des Klemmenisolierteils 16 und die Abluftwand 11 des Zwischenstücks 9 bilden im Bereich der Schmalseitenwand 5 einen zur Schmalseite 5 hin offenen Klemmenraum 23 zur Aufnahme einer Anschlussklemme. Dabei ist die Schmalseitenwand 5 teilweise durch eine erste und zweite Platte 24, 25 gebildet, die an dem Zwischenstück 9 und dem Klemmenisolierteil 16 angeformt sind.The clamping chamber partition wall 17 of the terminal insulating part 16 and the exhaust air wall 11 of the intermediate piece 9 form in the region of the narrow side wall 5 a narrow side 5 towards open terminal space 23 for receiving a terminal. In this case, the narrow side wall 5 is partially formed by a first and second plate 24, 25 which are integrally formed on the intermediate piece 9 and the terminal insulating part 16.

Die erste Platte 24 weist eine Ausbuchtung 26 an ihrer der oberen Breitseite 3 zuweisenden Schmalseite 5 auf. Wenn die obere Breitseite 3 des Gehäuses aufgesetzt ist, entsteht so zwischen der oberen Breitseite 3 und der ersten Platte ein länglicher Schlitz, der die erste Abluftöffnung 15 bildet. Diese ist also im Bereich der Ausbuchtung 26 zwischen der ersten Platte 24 und der obere Breitseite 3 des Gehäuses 2 gebildet.The first plate 24 has a bulge 26 on its narrow side 5 facing the upper broad side 3. When the upper broad side 3 of the housing is placed, so arises between the upper broad side 3 and the first plate, an elongated slot which forms the first exhaust port 15. This is thus formed in the region of the bulge 26 between the first plate 24 and the upper broad side 3 of the housing 2.

Auch die die zweite Platte 25 weist wenigstens eine Ausbuchtung 27 an ihrer der untere Breitseite 4 zuweisenden Schmalseite 5 auf, so dass die zweite Abluftöffnung 22 im Bereich der Ausbuchtung 27 zwischen der zweiten Platte 5 und der hinteren Breitseite 4 des Gehäuses 2 gebildet ist. Wie in der Fig. 4 zu sehen, ist die zweite Ausbuchtung hier durch eine kammartige Struktur realisiert, so dass die zweite Abluftöffnung 22 eine Reihe von übereinander angeordneten kleineren Einzellöchern ist.Also, the second plate 25 has at least one bulge 27 at its the lower broad side 4 facing narrow side 5, so that the second exhaust port 22 is formed in the region of the bulge 27 between the second plate 5 and the rear broad side 4 of the housing 2. Like in the Fig. 4 can be seen, the second bulge is realized here by a comb-like structure, so that the second exhaust port 22 is a series of smaller individual holes arranged one above the other.

An die Abluftwand 11 ist ein den ersten Abluftkanal 12 zur Befestigungsseite 6 hin begrenzender Steg 28 angeformt, sieh Fig. 3. Dieser Steg 28 führt die Abgase aus der Lichtbogenlöscheinrichtung heraus parallel zur Befestigungsseite zu den ersten und zweiten Abluftöffnungen 15, 22. Kurz hinter dem Ende 14 der Lichtbogenlöscheinrichtung 8 ist eine Stegöffnung 29 angebracht, die den Steg 28 in Richtung auf die Befestigungsseite 6 hin öffnet. Dadurch kann in zweiter Teilstrom 30 der Abgase durch die Stegöffnung 29 zu der Befestigungsseite 6 und dort durch eine dritte Abluftöffnung 31 nach außen geleitet werden. Die dritte Abluftöffnung 31 entsteht durch eine rillenartige Ausnehmung an der der Befestigungsseite 6 zuweisenden Kante des Zwischenstücks 9. Die obere Breitseite 3 des Gehäuses 2 hat an dieser Stelle eine Ausnehmung. Wenn die obere Breitseite 3 des Gehäuses 2 auf das Zwischenstück 9 aufgesetzt wird, entsteht dann an dieser Stelle die dritte Abluftöffnung 31.To the exhaust air wall 11 a the first exhaust duct 12 to the mounting side 6 towards limiting web 28 is formed, see Fig. 3 , This web 28 leads the exhaust gases out of the arc quenching device parallel to the attachment side to the first and second exhaust air openings 15, 22. Shortly behind the end 14 of the arc quenching device 8, a web opening 29 is attached, which opens the web 28 in the direction of the attachment side 6. As a result, in the second partial flow 30 of the exhaust gases can be passed through the web opening 29 to the mounting side 6 and there through a third exhaust port 31 to the outside. The third exhaust opening 31 is formed by a groove-like recess on the fastening side 6 facing edge of the intermediate piece 9. The upper broad side 3 of the housing 2 has at this point a recess. If the upper broad side 3 of the housing 2 is placed on the intermediate piece 9, then the third exhaust air opening 31 is formed at this point.

An der Abluftwand 11 des Zwischenstücks 9 sind Führungsstege 32 angebracht, die die Abgase aus der Lichtbogenlöscheinrichtung 8 auf den Abgasstrom 13 und den ersten und zweiten Teilstrom 21, 30 aufteilen. Ein erster, zentraler Steg 33 teilt den Abgasstrom in einen oberen und unteren Teilstrom auf. Der erste Steg trägt an seinem freien Ende eine Y-artige Verzweigung mit zwei Y-Schenkeln 34, 35. Dadurch wird der obere Teilstrom nach oben in Richtung auf die Frontseite hin abgelenkt, und ein Teil des oberen Teilstroms wird so der Zwischenöffnung 18 zugeführt. Ein anderer Teil des oberen Teilstroms umströmt den Y-Schenkel 35 und gelangt zu der ersten Abluftöffnung 15.On the exhaust air wall 11 of the intermediate piece 9 guide webs 32 are attached, which divide the exhaust gases from the arc quenching device 8 on the exhaust stream 13 and the first and second partial stream 21, 30. A first, central web 33 divides the exhaust gas flow into an upper and lower partial flow. The first web carries at its free end a Y-type branch with two Y-legs 34, 35. Thereby, the upper partial flow is deflected upward toward the front side, and a part of the upper partial flow is thus supplied to the intermediate opening 18. Another part of the upper part of the flow flows around the Y-leg 35 and reaches the first exhaust port 15th

Entsprechend wir ein erster Teil des unteren Teilstroms durch den unteren Y-Schenkel 34 nach unten in Richtung auf die Befestigungsseite 6 hin abgelenkt, wo er der dritten Abluftöffnung 31 zugeführt wird. Ein zweiter Teil des unteren Teilstrom umströmt den unteren Y-Schenkel 34 und gelangt ebenfalls zu der ersten Abluftöffnung 15.Accordingly, a first part of the lower partial flow is deflected downward by the lower Y-leg 34 in the direction of the fastening side 6, where it is fed to the third exhaust air opening 31. A second part of the lower partial flow flows around the lower Y-leg 34 and also reaches the first exhaust port 15.

Die vorliegende Erfindung umfasst neben den beschriebenen Ausführungsbeispielen auch beliebige Kombinationen bevorzugter Ausführungsformen sowie einzelner Ausgestaltungsmerkmale oder Weiterbildungen, sofern diese sich nicht gegenseitig ausschließen.In addition to the exemplary embodiments described, the present invention also includes any desired combinations of preferred embodiments as well as individual design features or developments, provided that they are not mutually exclusive.
