Description

Beschreibungdescription
Schutzschaltgerät in SchmalbauweiseProtection device in narrow construction
Die vorliegende Erfindung betrifft ein Schutzschaltgerät mit einem Gehäuse und darin angeordnet: eine Schalteinrichtung zum Schalten mindestens eines elektrischen Kontakts, eine Kurzschlussauslöseeinrichtung zum Auslösen der Schalteinrich¬ tung in einem Kurzschlussfall und eine Fehlerstromauslöseein- richtung zum Auslösen der Schalteinrichtung in einem Fehler¬ stromfall oder bei Differenzstrom.The present invention relates to a protective switching device with a housing and arranged therein: a switching device for switching at least one electrical contact, a short-circuit release device for triggering the Schalteinrich¬ device in a short circuit and a fault current tripping device for triggering the switching device in a Fehler¬ current case or differential current ,
Üblicherweise werden Schutzschaltgeräte in der Installations¬ technik beispielsweise als Leitungsschutzschalter, Fehler- Stromschutzschalter oder Differenzstromschutzschalter reali¬ siert. In den Leitungsschutzschaltern ist dabei häufig ein Kurzschlussauslöser und ein Überlastauslöser integriert. Die Schutzschaltgeräte sind entweder einzeln LS, FI oder als Ge¬ rätekombinationen (aneinander gereihte Geräte) FI/LS, LS/DI oder LS+FI-Block bekannt.Normally, circuit breakers in installation technology are realized, for example, as circuit breakers, fault current circuit breakers or residual current circuit breakers. The circuit breakers often incorporate a short-circuit release and an overload release. The circuit breakers are either individually LS, FI or as Ge¬ device combinations (juxtaposed devices) FI / LS, LS / DI or LS + FI block known.
Schutzschaltgeräte werden ferner häufig als Reiheneinbaugerä¬ te ausgeführt. Dabei stehen die einzelnen Komponenten in der Regel als Module zur Verfügung. So werden beispielsweise Lei- tungsschutzschalter und Fehlerstromschutzschalter jeweils in festen Modulbreiten angeboten. Die Breite derartiger modula- rer elektromechanischer Schaltgeräte wird in Teilungseinhei¬ ten entsprechend einer einschlägigen Norm angegeben. Bei¬ spielsweise entspricht eine Teilungseinheit (TE) dem Maß von 18 mm.Furthermore, protective switching devices are frequently designed as DIN rail mounted devices. The individual components are usually available as modules. For example, circuit breakers and residual current circuit breakers are offered in fixed module widths. The width of such modulo electromechanical switchgear is specified in Teilungseinhei¬ th according to a relevant standard. For example, a division unit (TE) corresponds to the dimension of 18 mm.
Soll nun ein kombiniertes Schutzschaltgerät wie beispielswei¬ se ein Leitungsschutzschalter mit Differenzstromschutzschal¬ ter oder Fehlerstromschutzschalter mit Leitungsschutzschalter installiert werden, so sind hierfür zwei Geräte notwendig, so dass sich eine Gesamtbreite von mehr als 1 TE ergibt. Dies bedeutet, dass eine derartige Schutzschaltgerätkombination mehr Einbauraum benötigt als ein einfacher Leitungsschutz¬ schalter mit der Breite 1 TE. Dies bedeutet aber auch, dass die Schutzfunktion eines in einen Schaltschrank eingebauten LeitungsschutzSchalters nicht ohne Weiteres erhöht werden kann, da dieser nicht in jedem Fall mit einem kombinierten Schutzschaltgerät der Breite 2 TE ausgetauscht werden kann.If now a combined protective switching device such as a circuit breaker with Differenzstromschutzschal¬ ter or residual current circuit breaker with circuit breaker are installed, so this two devices are necessary, so that there is a total width of more than 1 TE. This means that such a protective switching device combination requires more installation space than a simple circuit breaker with a width of 1 TE. However, this also means that the protective function of a built-in a circuit breaker circuit breaker can not be increased without further, as it can not be replaced in each case with a combined protection device width 2 TE.
Auch die Bauhöhe, z.B. wegen des Reihenabstands der Befesti¬ gungsschienen, und die Bautiefe, z.B. wegen der Verteilergrö- ße, eines modularen Schaltgeräts unterliegen in der RegelAlso the height, e.g. because of the row spacing of the fastening rails, and the overall depth, e.g. Because of the distributor size, a modular switchgear is usually subject
Einschränkungen. So sollte die Bautiefe typischerweise maxi¬ mal 70 mm und die Bauhöhe maximal 90 mm betragen.Restrictions. For example, the overall depth should typically be at most 70 mm and the overall height at most 90 mm.
Die Aufgabe der vorliegenden Erfindung besteht darin, kompak- te Schutzschaltgeräte mit erhöhter Schutzfunktionalität vor¬ zuschlagen.The object of the present invention is to propose compact protective switching devices with increased protection functionality.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Schutz¬ schaltgerät mit einem Gehäuse und darin angeordnet: eine Schalteinrichtung zum Schalten mindestens eines elektrischen Kontaktes,, eine Kurzschlussauslöseeinrichtung zum Auslösen der Schalteinrichtung in einem Kurzschlussfall und eine Feh- lerstromauslöseeinrichtung zum Auslösen der Schalteinrichtung in einem Fehlerstromfall oder bei Differenzstrom, wobei das Zentrum der Schalteinrichtung, das Zentrum der Kurzschluss¬ auslöseeinrichtung und das Zentrum der Fehlerstromauslöseein- richtung im Wesentlichen in einer Ebene angeordnet sind. D.h. die Fehlerstromauslöseeinrichtung besitzt die Funktion eines Fehlerstromschutzschalters und/oder Differenzstromschutz- Schalters. Dabei liegt diese Ebene vorzugsweise senkrecht zu einer Befestigungsschiene.According to the invention, this object is achieved by a protective switching device with a housing and arranged therein: a switching device for switching at least one electrical contact, a short-circuit tripping device for triggering the switching device in a short circuit and a fault current triggering device for triggering the switching device in a fault current event or at Differential current, wherein the center of the switching device, the center of the Kurzschluss¬ tripping device and the center of the fault current tripping device are arranged substantially in one plane. That the residual current device has the function of a residual current circuit breaker and / or differential current protection switch. In this case, this plane is preferably perpendicular to a mounting rail.
In vorteilhafter Weise kann durch die erfindungsgemäße Anord¬ nung der Schalteinrichtung, der Kurzschlussauslöseeinrichtung und der Fehlerstromauslöseeinrichtung ein Schutzschaltgerät einschließlich Fehlerstromauslösung in einem einzigen Modul der Breite 1 TE realisiert werden. Somit lässt sich bei be- stehenden Anlagen die Schutzfunktion erhöhen, indem bei¬ spielsweise ein üblicher Leitungsschutzschalter durch ein kombiniertes Schutzschaltgerät gleicher Breite ausgetauscht wird.Advantageously, by means of the arrangement according to the invention of the switching device, the short-circuit tripping device and the residual current tripping device, a protective switching device including fault current tripping can be realized in a single module of width 1 TE. Thus, at standing installations increase the protective function, for example by a conventional circuit breaker is replaced by a combined protection device of the same width.
Durch die kompaktere Gestaltung der Schutzschaltgeräte kann aber auch eine Verkleinerung von Verteilern erzielt werden. Gleichsam lässt sich auch die Anzahl der Abzweige mit hoher kombinierter Schutzfunktion bei herkömmlichen Verteilergrößen erhöhen. Letztlich kann durch die erfindungsgemäß kompakteDue to the more compact design of the protective switching devices but also a reduction of distribution can be achieved. Likewise, the number of branches with high combined protection function can be increased in conventional distribution sizes. Ultimately, by the present invention compact
Anordnung in dem kombinierten Schutzschaltgerät eine Verbes¬ serung der Selektivität erreicht werden.Arrangement in the combined protection device, a improvement of the selectivity can be achieved.
Vorzugsweise entspricht die Breite des Gehäuses, wie erwähnt, einem Normmaß. Dieses Normmaß kann speziell durch eine Tei¬ lungseinheit mit dem Maß von 18 mm definiert sein. Dies führt zu dem ebenfalls angedeuteten Vorteil, dass einzelne Module ohne weiteres ausgetauscht werden können, da sie gleiche Breite besitzen.Preferably, the width of the housing, as mentioned, corresponds to a standard dimension. This standard measure can be defined specifically by a Tei¬ treatment unit with the measure of 18 mm. This leads to the also indicated advantage that individual modules can be easily replaced because they have the same width.
Das erfindungsgemäße Schutzschaltgerät kann die Funktionali¬ täten eines Leitungsschutzschalters und eines Fehlerstrom¬ schutzschalters besitzen. Darüber hinaus kann dass Schutz¬ schaltgerät aber auch die Funktionalitäten eines Leitungs- schutzschalters und eines Differenzstromschutzschalters be¬ sitzen. Dies bedeutet, dass diese beiden Funktionalitäten in einem einzigen Gerät vereint werden können und die Breite dieses Geräts nicht über die eines einfachen Leitungsschutz¬ schalters hinausgehen muss.The protective switching device according to the invention can have the functionalities of a circuit breaker and a residual current circuit breaker. In addition, the protective switching device can also be equipped with the functionalities of a circuit breaker and of a residual current circuit breaker. This means that these two functions can be combined in a single device and the width of this device does not have to go beyond that of a simple circuit breaker.
An der Schalteinrichtung kann ferner eine Überlastauslöseein¬ richtung angeordnet sein. Prinzipiell kann diese Überlastaus¬ löseeinrichtung mit ihrem Zentrum ebenfalls auf der Ebene liegen, auf der auch die Zentren der anderen Komponenten lie- gen. Da aber ein Überlastauslöser in der Regel geringere Aus¬ maße als die genannten Komponenten des Schutzschaltgeräts be- sitzt, lässt es sich ohne weiteres auch an anderen Stellen zwischen diesen Komponenten anordnen.Furthermore, an overload release device can be arranged on the switching device. In principle, this overload release device with its center can also lie on the plane on which the centers of the other components are located. However, since an overload release usually has smaller dimensions than the abovementioned components of the protection switching device. sits, it can be easily arranged in other places between these components.
Besonders vorteilhaft lässt sich die vorliegende Erfindung für Schutzschaltgeräte einsetzen, die als Reiheneinbaugerät ausgestaltet sind. In diesem Fall kommen die oben genannten Vorteile noch mehr zur Geltung.The present invention can be used particularly advantageously for protective switching devices which are designed as a modular device. In this case, the advantages mentioned above are even more effective.
Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:The present invention will now be explained in more detail with reference to the accompanying drawings, in which:
FIG 1 eine Schnittansicht eines erfindungsgemäßen1 shows a sectional view of an inventive

FIG 2 eine Seitenansicht des Schutzschaltgeräts von FIG 1.2 shows a side view of the protective switching device of FIG. 1
Die nachfolgend näher geschilderten Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfin¬ dung dar.The embodiments described in more detail below represent preferred embodiments of the present invention.
Entsprechend einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist in einem Gehäuse 1 eines Schutz¬ schaltgeräts eine Schaltmechanik 2 mit mindestens einem e- lektrischen Kontakt angeordnet, die von einem Kurzschlussaus- löser 3, einem Überlastauslöser 4 und einem Fehlerstromauslö¬ ser 5 ausgelöst werden kann. Die Auslöser sind als rechtecki¬ ge Komponenten symbolisiert und die zugehörigen Auslösehebel als gestrichelte Linien angedeutet. An einer Kante 6 stoßen die beiden Hälften des Schutzschaltgerätegehäuses 1 zusammen. An den Stirnseiten des Gehäuses 1 sind Anschlussklemmen L und N angedeutet.According to a particularly preferred embodiment of the present invention, a switching mechanism 2 having at least one electrical contact, which can be triggered by a short-circuit release 3, an overload release 4 and a fault current trigger 5, is arranged in a housing 1 of a protective switching device. The triggers are symbolized as rectangular components and the associated tripping levers are indicated as dashed lines. At an edge 6, the two halves of the protective switching device housing 1 collide. At the front sides of the housing 1 terminals L and N are indicated.
Wie der Prinzipskizze von FIG 1 zu entnehmen ist, besitzen die Komponenten Kurzschlussauslöser 3, Schaltmechanik 2 und Fehlerstromauslöser 5 die größte Ausdehnung unter den hier relevanten Komponenten. Der Überlastauslöser 4 hingegen be¬ sitzt verhältnismäßig geringe Abmessungen. Erfindungsgemäß sind nun die großen Komponenten 2, 3 und 5 so angeordnet, dass ihre jeweiligen Zentren im Wesentlichen auf einer Ebene liegen. Im vorliegenden Beispiel verläuft diese Ebene durch die Mittellinie 7 entlang der Längserstreckung des Gehäuses 1 und somit senkrecht zu einer nicht dargestellten Befesti¬ gungsschiene, auf die das Gerät mit der in FIG 2 angedeuteten Aussparung aufschnappbar ist.As can be seen from the schematic diagram of FIG. 1, the components short-circuit release 3, switching mechanism 2 and fault current release 5 have the greatest extent among the components relevant here. The overload release 4, however, be¬ sits relatively small dimensions. According to the invention Now, the large components 2, 3 and 5 are arranged so that their respective centers are substantially on one level. In the present example, this plane extends through the center line 7 along the longitudinal extension of the housing 1 and thus perpendicular to a Befesti¬ not shown supply rail, to which the device with the recess indicated in FIG 2 can be snapped.
Der Überlastauslöser 4 besitzt gegenüber den anderen Kompo- nenten 2, 3 und 5 geringere Abmessungen, so dass er zwischen diesen leichter angeordnet werden kann. Im vorliegenden Bei¬ spiel liegt er etwas seitlich versetzt zwischen dem Überlast¬ auslöser 4 und dem Fehlerstromauslöser 5.The overload release 4 has compared to the other components 2, 3 and 5 smaller dimensions, so that it can be easily arranged between them. In the present example, it is slightly laterally offset between the overload release 4 and the residual current release 5.
Bei zweidimensionaler Projektion der wesentlichen Komponenten 2, 3 und 5 auf die Grundfläche des Schutzschaltgeräts liegen diese in einer Reihe hintereinander. Dadurch kann eine Gehäu¬ sebreite entsprechend einer Teilungseinheit TE gewährleistet werden.In the case of a two-dimensional projection of the essential components 2, 3 and 5 on the base area of the protective switching device, these are arranged one behind the other in a row. As a result, a housing width corresponding to a graduation unit TE can be ensured.
In FIG 2 ist -das Schutzschaltgerät von FIG 1 im Querschnitt dargestellt. Hier ist die zweidimensionale Verteilung der Schaltmechanik 2, des Kurzschlussauslösers 3 und des Fehler¬ stromauslösers 5 in der oben genannten Ebene zu erkennen. Auch die Anordnung des Überlastauslösers 4 unterhalb derIn FIG 2, the protective switching device of Figure 1 is shown in cross section. Here, the two-dimensional distribution of the switching mechanism 2, the short-circuit release 3 and the Fehler¬ current release 5 can be seen in the above-mentioned level. The arrangement of the overload release 4 below the
Schaltmechanik 2 ist in FIG 2 wiedergegeben. Darüber hinaus symbolisieren auch hier gestrichelte Linien die einzelnen Auslösehebel an der Schaltmechanik 2. Die Schnittlinie für- den Schnitt von FIG 1 ist mit A gekennzeichnet.Switching mechanism 2 is shown in FIG 2. In addition, dashed lines also symbolize the individual trigger levers on the switching mechanism 2. The section line for the section of FIG. 1 is marked A.
Die für den vorliegenden Fall wesentlichen Komponenten Schaltmechanik 2, Kurzschlussauslöser 3 und Fehlerstromauslö¬ ser 5 liegen mit ihren Zentren entsprechend dem Beispiel von FIG 1 exakt auf einer Ebene, wobei die Auslöser auf die ge- meinsame Schaltmechanik 2 wirken. Entsprechend der Gestaltung der Schaltmechanik 2 und der Auslösehebel kann es jedoch not¬ wendig sein, dass die Zentren dieser Komponenten etwas aus der Ebene gerückt sind. Dennoch besteht das Wesen der erfin¬ dungsgemäßen Anordnung darin, die dritte Dimension senkrecht zu der angesprochenen Ebene sowenig wie möglich auszunutzen. Somit kann ein Schutzschaltgerät mit voluminösen Funktions- bauteilen wie beispielsweise Magnetauslöser und Wandler sowie Funktionsbauteilen, die weniger Volumenbedarf haben wie bei¬ spielsweise thermische Auslöser, in Schmalbauweise realisiert werden. Dabei ist vorzugsweise die Breite des Kombigeräts auf 1 TE beschränkt, die Bautiefe liegt unter 70 mm und die Bau- höhe unter 90 mm. Somit ist es möglich, die für die kombi¬ nierte Schutzfunktion Überlast, Kurzschluss und Fehlerstrom erforderlichen Sensoren und Aktoren gleichmäßig in dem zur Verfügung stehenden Konstruktionsvolumen unterzubringen. The essential for the present case switching mechanism 2, short-circuit release 3 and Fehlerstromauslö¬ ser 5 are with their centers according to the example of FIG 1 exactly on a plane, the triggers act on the common switching mechanism 2. However, according to the design of the switching mechanism 2 and the release lever, it may be necessary for the centers of these components to be somewhat small moved to the plane. Nevertheless, the essence of the arrangement according to the invention is to make as little use of the third dimension perpendicular to the plane as possible. Thus, a protective switching device with voluminous functional components such as magnetic releases and transducers as well as functional components that have less volume requirements, such as thermal triggers, for example, can be realized in a narrow construction. The width of the combi unit is preferably limited to 1 TE, the overall depth is less than 70 mm and the overall height is less than 90 mm. Thus, it is possible to uniformly accommodate the sensors and actuators required for the combined protection function overload, short-circuit and fault current in the available design volume.
