Description

Die Erfindung betrifft einen Leistungsschalter mit einem thermischen Auslöser, an welchem über einen Kontaktbrückenträger ein bewegliches Schaltstück angeordnet ist, welches auf einem Federkörper gelagert ist und gegenüberliegend von festen Schaltstücken angeordnet ist.The invention relates to a circuit breaker with a thermal release to which a movable contact piece is arranged via a contact bridge carrier, which is mounted on a spring body and is arranged opposite of fixed contact pieces.

Leistungsschalter werden in verschiedenen Baugrößen entwickelt. Eine Baugröße setzt sich dabei aus Gerätevarianten mit einer sinnvoll aufbauenden Nennstromreihe zusammen. Mit zunehmendem Nennstrom eines Gerätes steigt dessen Verlustleistungsumsatz überproportional stark an. Die Gerätevariante mit dem höchsten Nennstrom bei einer gegebenen Baugröße ist dadurch bestimmt, dass eben für diesen Strom der Verlustleistungsumsatz bei gegebenem Gehäusevolumen noch ohne nachteilige Folgen für die Anforderung des Schaltgerätes über seine Lebenszeit bleibt. Will man zu noch höheren Nennströmen kommen, entwickelt man eine größere Bauform. Aus Kundensicht ist es jedoch wünschenswert, den maximalen Nennstrom innerhalb einer Baugröße noch weiter nach oben zu treiben. Um dies zu erreichen, sind Maßnahmen zu ergreifen, die den Wärmetransport aus dem Gehäusevolumen technisch effizienter gestalten.Circuit-breakers are developed in various sizes. One size is composed of device variants with a meaningful series of rated current. As the rated current of a device increases, its power dissipation increases disproportionately. The device variant with the highest rated current for a given size is determined by the fact that just for this stream of power loss remains at a given housing volume without adverse consequences for the requirement of the switching device over its lifetime. If you want to get even higher rated currents, you develop a larger design. From the customer's point of view, however, it is desirable to increase the maximum rated current within one size even further. To achieve this, measures must be taken to make the heat transport from the housing volume technically more efficient.

Es gibt im Prinzip zwei Möglichkeiten mit hohen Temperaturen innerhalb eines Schutzgehäuses auf Grund unvermeidbarer elektrischer Verlustleistungen umzugehen. Zum Einen kann man alle Materialien so weit optimieren, dass sie ihre funktionalen Anforderungen auch auf hohem Temperaturniveau erfüllen. Dies ist jedoch oftmals keine wirtschaftliche Lösung. Das andere Vorgehen besteht darin, den Abtransport der erzeugten Wärmen aus dem Gehäuse durch technische Maßnahmen zu forcieren. Für elektronische Produkte sind aktive Kühlmaßnahmen mittels Gehäuselüfter, Heat Pipe-Anordnungen oder gar Kühlmittelkreisläufe Stand der Technik. Um lokal erzeugte große Wärmemengen damit auch abführen zu können, werden diese Wärmen mittels Kühlkörpern auf große Flächen verteilt. Dabei sind die Kühlkörper thermisch an die Bauteile mit hoher elektrischer Verlustleistung angebunden, aber elektrisch davon isoliert. Komplett passiv gekühlte Systeme sind dabei so konstruiert, dass die notwendigen Kühlkörper direkt von der Umgebungsluft angeströmt werden können.There are in principle two ways to handle high temperatures within a protective housing due to unavoidable electrical power losses. On the one hand, all materials can be optimized to meet their functional requirements, even at high temperatures. However, this is often not an economical solution. The other approach is to force the removal of the generated heat from the housing by technical measures. For electronic products, active cooling measures by means of housing fans, heat pipe arrangements or even coolant circuits are state of the art. In order to be able to dissipate locally generated large amounts of heat so that these are warming distributed by means of heat sinks on large areas. The heat sinks are thermally connected to the components with high electrical power loss, but electrically isolated from it. Fully passively cooled systems are designed in such a way that the necessary heat sinks can be directly flown by the ambient air.

Aus der DE 842 809 C geht eine Schaltpatrone mit mindestens einem magnetisch beeinflussten Schaltelement hervor, wobei die magnetischen Gegenpole, die fest stehenden Kontakte und die Anorndung des Schaltelements ingesamt derart ausgebildet sind, dass die Wärmeabfuhr aus dem Schaltelement im Wesentlichen durch Wärmeleitung in Längsrichtung des Schaltelements an die feststehenden Kontakte erfolgt.From the DE 842 809 C is a switching cartridge with at least one magnetically influenced switching element, the magnetic opposite poles, the fixed contacts and the Anorndung of the switching element are designed in such a way that the heat dissipation from the switching element substantially by heat conduction in the longitudinal direction of the switching element to the fixed contacts.

Die DE 876 563 C beschreibt einen Leistungsschalter mit einem thermischen Auslöser, an welchem über einen Kontaktbrückenträger ein bewegliches Schaltstück angeordnet ist, welches auf einem Federkörper gelagert ist und gegenüberliegend von festen Schaltstücken angeordnet ist.The DE 876 563 C describes a circuit breaker with a thermal release on which a contact bridge carrier a movable contact piece is arranged, which is mounted on a spring body and is arranged opposite of fixed contact pieces.

Der Nachteil am Stand der Technik besteht darin, dass die bisherigen Entwärmungselemente nicht platzoptimiert im Leistungsschalter angeordnet werden konnten.The disadvantage of the prior art is that the previous Entwärmungselemente could not be placed optimally optimized in the circuit breaker.

Die Aufgabe der vorliegenden Erfindung besteht demgemäß darin, einen Leistungsschalter zu schaffen, der einen platzoptimierten Entwärmungsprozess ermöglicht.The object of the present invention is therefore to provide a circuit breaker, which allows a space-optimized Entwärmungsprozess.

Diese Aufgabe wird durch einen Leistungsschalter mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche.This object is achieved by a circuit breaker having the features of patent claim 1. Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.

Erfindungsgemäß wird diese Aufgabe durch einen Leistungsschalter mit einem thermischen Auslöser gelöst, an welchem über einen Kontaktbrückenträger ein bewegliches Schaltstück angeordnet ist, welches auf einem Federkörper gelagert ist und gegenüberliegend von festen Schaltstücken angeordnet ist. Die Erfindung zeichnet sich dabei dadurch aus, dass eine Entwärmungsvorrichtung aus einem Wärme ableitenden Material jeweils seitlich an den festen Schaltstücken angeordnet ist.According to the invention this object is achieved by a circuit breaker with a thermal release, on which a contact bridge carrier a movable contact piece is arranged, which is mounted on a spring body and is arranged opposite of fixed contact pieces. The invention is characterized in that a cooling device made of a heat dissipating material is arranged laterally on the fixed contact pieces.

Erfindungsgemäß erfolgt die Lösung des Entwärmungsproblems durch Eröffnung eines zweiten nennenswerten Entwärmungsweges entlang der Strombahn, wenn man von der Hauptwärmequelle, also der Kontaktbrücke ausgeht. Dieser neben der ins Gerät führenden ersten Entwärnungsrichtung zusätzliche zweite Weg, führt die Stromschiene entlang von den Kontaktstellen weg parallel zu den Löschblechen in Richtung der Stirnseiten. Bisher war dieses Ende der Strombahnausbildung wärmetechnisch gesehen eine Sackgasse und diente nur der Führung des Kurzschlusslichtbogens in Richtung Löscheinrichtung. Die Realisierung eines zweiten Wärmeweges kann mittels Einbringen von großflächigen Kühlelementen, wie zum Beispiel Kühlblechen, vorzugsweise in die Phasentrennwände von Leistungsschaltern erreicht werden. Diese Kühlelemente sind direkt oder indirekt also zum Beispiel elektrisch isoliert und gut wärmeleitend mit den Stromschienen der Geräte verbunden. Sie erstrecken sich dann flächig in Hohlräume in den meist aus Kunststoff bestehenden Kammertrennwänden der Schaltgeräte.According to the solution of the Entwärmungsproblems by opening a second significant Entwärmungsweges along the current path, if one starts from the main heat source, so the contact bridge. This next to the leading direction of the first Entwärnungsrichtung additional second way leads the busbar along the contact points away parallel to the quenching plates in the direction of the end faces. So far was this end of the current train training thermally a dead end and served only the leadership of the short arc in the direction of extinguishing equipment. The realization of a second heat path can be achieved by introducing large-area cooling elements, such as cooling plates, preferably in the phase barriers of circuit breakers. These cooling elements are therefore directly or indirectly so for example electrically isolated and good heat conducting connected to the busbars of the devices. They then extend flat in cavities in the usually made of plastic chamber partitions of the switching devices.

Besonders vorteilhaft ist die Fortführung dieser Kühlfahnen in den Teil der Kammertrennrippen hinein, der außerhalb des Gerätekorpus liegt. Diese außerhalb gelegenen Rippen dienen heute bisher in erster Linie der Vergrößerung der Isolationsstrecke, also der Luft- und Kriechstrecke zwischen den einzelnen Polen von Geräten. Wenn die Wärmedecke des thermisch schlecht leitenden Rippenkunststoffes klein bleibt, kann genügend Wärme hindurch an die Umgebung abgegeben werden. Wenn die Rippen zusätzlich über die gesamte Gerätehöhe verlaufen, ist die an die umgebende Luftwärme ableitende Fläche relativ groß. Im Übrigen bleiben diese Rippen bei Anordnung der Geräte dicht an dicht im Gegensatz zu den Geräteseitenflächen unverdeckt und damit überaus wirkungsvoll. Ein elektrischer Bediener-Berührschutz der metallischen Kühlfahnen ist durch die Kunststoffummantelung gegeben.Particularly advantageous is the continuation of these cooling flags in the part of the chamber separating ribs, which lies outside of the device body. Up to now, these outlying ribs primarily serve to increase the insulation distance, ie the clearance and creepage distance between the individual poles of devices. If the thermal blanket of the thermally poorly conducting ribbed plastic remains small enough heat can be dissipated to the environment. If the ribs additionally extend over the entire height of the device, the surface dissipating to the surrounding air heat is relatively large. Incidentally, these ribs remain in the arrangement of the devices close to tight in contrast to the device side surfaces uncovered and thus extremely effective. An electrical operator contact protection of the metallic cooling vanes is given by the plastic sheath.

Eine weitere den Wirkungsgrad steigernde Alternative besteht darin, die Kühlfahnen nicht berührungsgeschützt innerhalb der Kunststoffrippen zu verwenden, sondern direkt an Luft zu bringen. Der notwendige Bediener-Berührschutz müsste in diesem Fall über zwischen Strombahn und Kühlfahne elektrisch isolierende, aber thermisch gut leitende Zwischenschichten, wie zum Beispiel aus der Halbleiter-Leistungsmodultechnik bekannte Wärmeleitfolien oder keramische Plättchen sichergestellt werden.Another efficiency-increasing alternative is not to use the cooling vanes touch-protected within the plastic ribs, but to bring directly into the air. In this case, the necessary operator contact protection would have to be ensured by means of electrically insulating but thermally well-conducting intermediate layers, such as heat conducting foils or ceramic platelets known from semiconductor power module technology, between the current path and the cooling lug.

Ein Vorteil der erfindungsgemäßen Entwärmungsvorrichtung besteht darin, dass ein zweiter effektiver Strombahn-Entwärmungsweg gefunden wurde, damit größere Verlustleistungen abführbar sind, so dass höhere Nennstromdichten der Geräte bei gleichbleibendem Bauvolumen ermöglicht werden.
Ein konstruktiver Vorteil besteht darin, dass die Wärmeabgabeflächen nicht verbaubar beziehungsweise nicht abgedeckt werden. Dadurch kann eine effiziente Wärmeabgabe erfolgen. Auf Grund des von der Kontaktstelle aus betrachteten zweiten Entwärmungsweges in die Kühlfläche hinein, erfolgt eine günstige Entkopplung des thermischen Auslösers, zum Beispiel eines Bimetalls von wärmetechnischen Schwankungen der Kontaktübergangsstelle. Dadurch wird das Auslöseverhalten des Gerätes günstig beeinflusst. Durch die erfindungsgemäße Entwärmungsvorrichtung wird somit sowohl eine Senkung des Temperaturniveaus, als auch eine Verbesserung des Grenzstromauslöseverhaltens erreicht.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass die Entwärmungsvorrichtung aus einem wärmeleitenden Material insbesondere einem Kühlblech ausgebildet ist. Diese großen Kühlbleche ermöglichen es, dass die bisher innerhalb der Leistungsschalter mehr oder weniger punktuell in der Strombahn vorhandene Wärmemenge durch verhältnismäßig große Kühl- beziehungsweise Wärmeverteilflächen besser abgeleitet werden. Diese Kühlbleche sind in vorteilhafter Weise auch als Kühlrippen ausgebildet, die ebenfalls einen effizienten Wärmetransport ermöglichen.An advantage of the cooling device according to the invention is that a second effective current path Entwärmungsweg was found so that larger power losses are dissipated, so that higher rated current densities of the devices are made possible with a constant volume.
A constructive advantage is that the heat-emitting surfaces are not buildable or not covered. This can be done an efficient heat dissipation. On the basis of the second Entwärmungsweges considered by the contact point in the cooling surface, there is a favorable decoupling of the thermal release, for example a bimetal of thermal fluctuations in the contact transition point. As a result, the triggering behavior of the device is favorably influenced. The cooling device according to the invention thus achieves both a reduction in the temperature level and an improvement in the limiting current tripping behavior.
In a particularly advantageous embodiment, it is provided that the cooling device is formed of a heat-conducting material, in particular a cooling plate. These large cooling plates make it possible that the amount of heat previously present within the circuit breaker more or less selectively in the current path are better dissipated by relatively large cooling or heat distribution surfaces. These cooling plates are advantageously designed as cooling fins, which also allow efficient heat transfer.

In der erfindungsgemäßen Entwärmungsvorrichtung ist vorgesehen, dass die Entwärmungsvorrichtung an den festen Schaltstücken sowie an einer Verbindungszunge des thermischen Auslösers angeordnet ist. Diese seitliche Platzierung der erfindungsgemäßen Entwärmungsvorrichtung an den festen Schaltstücken ermöglicht eine platzoptimierte Anordnung, die den effektiven Wärmetransport ermöglicht.In the cooling device according to the invention it is provided that the Entwärmungsvorrichtung is arranged on the fixed contact pieces and on a connecting tongue of the thermal release. This lateral placement of the cooling device according to the invention on the fixed contact pieces allows a space-optimized arrangement, which allows the effective heat transfer.

Zudem ist in vorteilhafter Weise vorgesehen, dass die Entwärmungsvorrichtung in Kammertrennwänden des Schaltgeräts angeordnet ist. Die erfindungsgemäßen Kühlflächen sind auf diese Weise isoliert und platzoptimiert zwischen den Phasentrennwänden der Leistungsschalter positioniert. Zudem können die Kühlflächen, wenn sie zwischen den Phasen angeordnet sind, über den Gerätegrundkorpus hinaus, ein- oder beidseitig in außenliegende, gegebenenfalls isolierte Rippen hinein, ausgedehnt werden. Der Vorteil besteht darin, dass die Wärmeabfuhr über diese außenliegenden großflächigen Rippen wegen des direkten Kontakts zur umgebenden Luft äußerst effizient ist.In addition, it is advantageously provided that the Entwärmungsvorrichtung is arranged in the chamber partitions of the switching device. The cooling surfaces according to the invention are isolated in this way and positioned optimally positioned between the phase barriers of the circuit breaker. In addition, the cooling surfaces, if they are arranged between the phases beyond the basic body of the device, can be extended on one or both sides into external, possibly insulated, ribs. The advantage is that the heat dissipation through these external large-area fins is extremely efficient because of the direct contact with the surrounding air.

Durch die hier vorgestellte erfindungsgemäße Entwärmungsvorrichtung der Leistungsschalter wird ein zweiter effektiver Strombahn-Entwärmungsweg ermöglicht, damit größere Verlustleistungen abführbar sind, so dass höhere Nennstromdichten der Geräte bei gleichbleibendem Bauvolumen möglich sind. Dabei werden die Wärmeabgabeflächen in Form von Kühlblechen so platzoptimiert in den Leistungsschalterintegriert, dass die Flächen weder verbaut noch abgedeckt werden. Auf Grund des von der Kontaktstelle aus betrachteten zweiten Entwärmungsweges in die Kühlbleche erfolgt in vorteilhafter Weise eine günstige Entkopplung des thermischen Auslösers von Wärme technischen Schwankungen der Kontaktübergangsstelle, wodurch auch das Auslöseverhalten des Leistungsschalters günstig beeinflusst wird. Durch die hier beschriebene platzoptimierte Entwärmungsvorrichtung ist somit sowohl eine Senkung des Temperaturniveaus insgesamt, als auch eine Verbesserung des Grenzstromauslöseverhaltens möglich.The inventive cooling device of the circuit breaker presented here makes possible a second effective current path cooling path, so that greater power losses can be dissipated, so that higher rated current densities of the devices are possible with the same construction volume. The heat dissipation surfaces in the form of cooling plates are space-optimally integrated into the circuit breaker so that the surfaces are neither installed nor covered.

The space-optimized cooling device described here thus makes it possible to lower the overall temperature level as well as to improve the limiting current tripping behavior.

Weitere Wärmefelder 23, 24, die etwas weniger ausgeprägt sind als die Wärmefelder 19, 20, befinden sich an den anderen zwei Schenkeln 25, 26 der festen Schaltstücke 8, 9. Nach diesen etwas geringer ausgeprägten Wärmefeldern 23, 24 wird die Wärme in Richtung der Anschlussklemmen 13 sowie über den thermischen Auslöser 2 zur Anschlussklemme 16 weiter abgeführt.In Fig. 1 In addition, the heat dissipation behavior 17, 18 is shown after a switching operation. After a switching operation, first large heat fields 19, 20 form on the free legs 21, 22 of the fixed contact piece 8, 9, which do not lead to the terminal 13 and the thermal release 2. Further heat fields 23, 24, which are slightly less pronounced than the heat fields 19, 20, are located on the other two legs 25, 26 of the fixed contact pieces 8, 9. After these slightly less pronounced heat fields 23, 24, the heat in the direction of Terminals 13 and further removed via the thermal release 2 to the terminal 16.

Fig. 2 zeigt die Darstellung nach Fig. 1, wobei an den freien Schenkeln 21, 22 der festen Schaltstücke 8, 9 Entwärmungsvorrichtungen 27, 28 angeordnet sind. Diese Entwärmungsvorrichtungen 27, 28 können beispielsweise als Kühlbleche oder Kühlrippen ausgebildet sein. Aus Fig. 2 geht weiterhin hervor, dass die Wärmefelder 19, 20 durch die erfindungsgemäße Entwärmungsvorrichtung 27, 28 deutlich geringer ausgebildet sind. Fig. 2 shows the representation Fig. 1 , 9 on the free legs 21, 22 of the fixed contact pieces 8, 9 Entwärmungsvorrichtungen 27, 28 are arranged. These Entwärmungsvorrichtungen 27, 28 may be formed for example as cooling plates or cooling fins. Out Fig. 2 goes on show that the heat fields 19, 20 are significantly reduced by the Entwärmungsvorrichtung 27, 28 according to the invention.

In Fig. 3 ist eine besonders vorteilhafte Ausführungsform der erfindungsgemäßen Entwärmungsvorrichtung 27, 28 dargestellt. In diesem Beispiel ist die Entwärmungsvorrichtung 27, 28 als Kühlblech 29 dargestellt. Die Kühlbleche 29 sind vorzugsweise parallel zueinander ausgerichtet und an den festen Schaltstücken 8, 9 sowie an der Verbindungszunge 15 angeordnet.In Fig. 3 a particularly advantageous embodiment of the invention Entwärmungsvorrichtung 27, 28 is shown. In this example, the cooling device 27, 28 is shown as a cooling plate 29. The cooling plates 29 are preferably aligned parallel to one another and arranged on the fixed contact pieces 8, 9 and on the connecting tongue 15.

In Fig. 4 ist die Darstellung aus Fig. 3 gezeigt, wobei die Kühlbleche 29 sich über die Schaltergrundkontur hinaus in Form isolierter, ggf. gehäuseintegrierter Rippen 30 ausdehnen.In Fig. 4 is the presentation off Fig. 3 shown, wherein the cooling plates 29 extends beyond the switch base contour in Extend the shape of insulated, optionally housing-integrated ribs 30.

Fig. 5 zeigt eine weitere, platzoptimierte Gehäuseanordnung der erfindungsgemäßen Kühlbleche 29. Hier sind die Kühlflächen vorzugsweise in phasentrennenden Gehäusezwischenwänden 31 angeordnet. Fig. 5 shows a further, space-optimized housing arrangement of the cooling plates 29 according to the invention. Here, the cooling surfaces are preferably arranged in phase-separating housing intermediate walls 31.

Durch die hier vorgestellte erfindungsgemäße Entwärmungsvorrichtung für Leistungsschalter, wird ein zweiter effektiver Strombahn-Entwärmungsweg ermöglicht, damit größere Verlustleistungen abführbar sind, so dass höhere Nennstromdichten der Geräte bei gleichbleibendem Bauvolumen möglich sind. Dabei werden die Wärmeabgabeflächen in Form von Kühlblechen so platzoptimiert in das Schaltgerät integriert, dass die Flächen weder verbaut noch abgedeckt werden. Auf Grund des von der Kontaktstelle aus betrachteten zweiten Entwärmungsweges in die Kühlbleche erfolgt in vorteilhafter Weise eine günstige Entkopplung des thermischen Auslösers von wärmetechnischen Schwankungen der Kontaktübergangsstelle, wodurch auch das Auslöseverhalten des Schaltgeräts günstig beeinflusst wird. Durch die hier beschriebene platzoptimierte Entwärmungsvorrichtung ist somit sowohl eine Senkung des Temperaturniveaus insgesamt, als auch eine Verbesserung des Grenzstromauslöseverhaltens möglich.The cooling device for circuit breakers according to the invention presented here enables a second effective current path cooling path, so that greater power losses can be dissipated, so that higher rated current densities of the devices are possible with the same construction volume. The heat dissipation surfaces are integrated in the form of cooling plates so space optimized in the switching device that the surfaces are neither installed nor covered. Due to the consideration of the contact point from the second Entwärmungsweges in the cooling plates is advantageously a favorable decoupling of the thermal release of thermal fluctuations of the contact transition point, whereby the tripping behavior of the switching device is favorably influenced. The space-optimized cooling device described here thus makes it possible to lower the overall temperature level as well as to improve the limiting current tripping behavior.
