Description

Die Erfindung betrifft ein Schutzschaltgerät mit einer Statusanzeigevorrichtung.The invention relates to a protective switching device with a status indicator.

Sie ist insbesondere für jedes Schutzschaltgerät geeignet, das eine Vielzahl von Funktionalitäten aufweist. Dies ist z. B. bei einem Lichtbogenschutzschalter der Fall, der serielle und parallele Störlichtbögen erkennen kann, mit der Fähigkeit zum Durchführen eines Selbsttests ausgestattet ist, eine Überspannung erfassen kann, einen Fehlerstromschutz bereitstellt, Überlast und Kurzschluss erkennen kann und dergleichen.It is particularly suitable for any protection device that has a variety of functionalities. This is z. For example, in an arcing circuit breaker, which can detect serial and parallel arcs, is capable of performing a self-test, can detect overvoltage, provides residual current protection, can detect overload and short circuit, and the like.

Je mehr Funktionalitäten das Schutzschaltgerät hat, desto komplexer wird die Anzeige des Status. Herkömmliche Statusanzeigevorrichtungen weisen einen Lichtleiter auf, in den eine Diode Licht einkoppeln kann. Es kann dann zwischen drei Zuständen unterschieden werden, nämlich, dass die Diode ausgeschaltet ist, dass sie eingeschaltet ist und dass sie mit einer bestimmten Frequenz blinkt. Man ist auch dazu übergegangen, eine zweite Diode mit einem zugehörigen Lichtleiter vorzusehen, in dem die Diode Licht einkoppelt. Auf diese Weise lässt sich die Zahl der möglichen Statusanzeigen auf neun erhöhen. Diese Zahl ergibt sich aus der Anzahl der möglichen Kombinationen von jeweils drei Zuständen bei zwei voneinander unabhängigen Einheiten aus Diode und Lichtleiter.The more functions the protection relay has, the more complex the display of the status becomes. Conventional status display devices have a light guide into which a diode can couple light. It is then possible to distinguish between three states, namely that the diode is switched off, that it is switched on and that it flashes at a certain frequency. It has also gone over to provide a second diode with an associated light guide in which the diode couples light. In this way, the number of possible status displays can be increased to nine. This number results from the number of possible combinations of three states each with two independent units of diode and light guide.

Der Lichtleiter muss in dem Schutzschaltgerät von einer Platine (Leiterplatte) bis zur Vorderseite des Schutzschaltgeräts geführt sein. Auf der Vorderseite muss dann Platz in der Größenordnung des Querschnitts des Lichtleiters zur Verfügung stehen, damit das Licht aus diesem austreten kann. Werden zwei Lichtleiter vorgesehen, so muss entsprechend viel Platz für zwei Lichtleiterenden an der Vorderseite zur Verfügung stehen; der Platz an der Vorderseite ist jedoch beschränkt.The light guide must be routed in the circuit breaker from a printed circuit board (PCB) to the front of the circuit breaker. Space must then be available on the front side in the order of magnitude of the cross-section of the light guide so that the light can escape from it. If two light guides are provided, there must be a corresponding amount of space are available for two optical fiber ends at the front; however, the space at the front is limited.

Es ist eine Aufgabe der vorliegenden Anmeldung, auf Platz sparende Weise die Anzahl der möglichen Arten von Statusanzeigen zu erhöhen.It is an object of the present application to increase, in a space-saving manner, the number of possible types of status indications.

Die Aufgabe wird in einem Aspekt durch ein Schutzschaltgerät mit den Merkmalen gemäß Patentanspruch 1 und in einem anderen Aspekt durch ein Verfahren mit den Merkmalen gemäß Patentanspruch 6 gelöst.The object is achieved in one aspect by a protective switching device with the features according to claim 1 and in another aspect by a method having the features according to claim 6.

Erfindungsgemäß umfasst somit die Statusanzeigevorrichtung einen Lichtleiter und zwei Dioden, welche Licht jeweils unterschiedlicher Farbe in denselben Lichtleiter einzukoppeln ausgelegt sind. Die beiden Dioden sind von einer Steuereinrichtung des Schutzschaltgeräts unabhängig voneinander und somit auch gleichzeitig miteinander ansteuerbar.According to the invention, the status display device thus comprises a light guide and two diodes, which are each designed to couple light of different colors into the same light guide. The two diodes can be controlled by a control device of the protection device independently of each other and thus simultaneously with each other.

Es lassen sich somit bezüglich der Farbe bereits mindestens vier Zustände voneinander unterscheiden, nämlich neben dem Zustand des Ausgeschaltetseins beider Dioden und neben dem Bereitstellen der jeweiligen Farben der beiden Dioden einzeln gibt es auch noch den Zustand, dass die Farben der beiden Dioden miteinander gemischt sind, wenn die Dioden gleichzeitig miteinander angesteuert werden. Anhand dieser vier Zustände lassen sich, wenn die Dioden auch noch zum Blinken gebracht werden können, bis zu 15 unterschiedliche Arten einer Statusanzeige bereitstellen, die von einem Benutzer gut unterscheidbar sind. Dadurch, dass nur ein Lichtleiter verwendet wird, in den beide Dioden das Licht einkoppeln, steht auf der Vorderseite des Schutzschaltgeräts noch Platz für etwas anderes zur Verfügung, z. B. für eine Aufschrift auf dem Schutzschaltgerät (etwa mit einer Kennung).Thus, at least four states can already be distinguished from each other in terms of color, namely in addition to the state in which both diodes are switched off and in addition to providing the respective colors of the two diodes individually, there is also the state that the colors of the two diodes are mixed with one another, when the diodes are driven together at the same time. Based on these four states, if the diodes can still be made to blink, up to 15 different types of status indication can be provided that are well distinguishable by a user. The fact that only one light guide is used, in which both diodes couple the light, there is still room for something else available on the front of the circuit breaker, z. B. for an inscription on the protection device (such as with an identifier).

Bei einer bevorzugten Ausführungsform wird eine Doppelleuchtdiode verwendet (so genannte Bicolor-LEDs), bei dem beide Dioden zu einem einzigen Bauelement gehören. Ein solches Bauelement ist auf dem Markt erhältlich und ermöglicht es, beide Dioden in kompakter Form in dem Schutzschaltgerät vorzusehen, und dort auch leicht anzuschließen.In a preferred embodiment, a dual light emitting diode is used (so-called bi-color LEDs) in which both diodes belong to a single component. Such a device is available on the market and makes it possible to provide both diodes in a compact form in the protective switching device, and there also easy to connect.

Bei einer bevorzugten Ausführungsform der Erfindung sind die beiden Dioden derart voneinander unabhängig ansteuerbar, dass sie jeweils blinken. Das Blinken beinhaltet bevorzugt, dass es gleich lange Intervalle von Leuchten und Pausen gibt. Bei geeigneter Kombination lässt sich somit, wie bereits erwähnt, die Anzahl der Statusanzeigemöglichkeiten erhöhen.In a preferred embodiment of the invention, the two diodes can be controlled independently of one another such that they each blink. The flashing preferably includes equal intervals of lights and pauses. With a suitable combination, as already mentioned, the number of status display options can thus be increased.

Das erfindungsgemäße Schutzschaltgerät ist in einer bevorzugten Ausführungsform ein Lichtbogenschutzschalter, der über eine Vielzahl von Funktionalitäten verfügt, sodass eine Statusanzeige vielfältiger Art erwünscht ist. Dies gilt insbesondere dann, wenn der Lichtbogenschutzschalter einen integrierten Überspannungsschutz und/oder einen Fehlerstromschutz bereitstellt. Weitere Funktionalitäten des Lichtbogenschutzschalters sind möglich.The protective switching device according to the invention is in a preferred embodiment, an arc protection switch, which has a variety of functionalities, so that a status indicator of various types is desired. This is especially true when the arc circuit breaker provides an integrated overvoltage protection and / or residual current protection. Further functionalities of the arc circuit breaker are possible.

Das erfindungsgemäße Verfahren zum Bereitstellen einer Statusanzeige an einem Schutzschaltgerät (nämlich insbesondere einem Lichtbogenschutzschalter) ist dadurch gekennzeichnet, dass zum Bereitstellen einer Mehrzahl von Statusmeldungen zwei Leuchtdioden Licht von jeweils unterschiedlicher Farbe in einen Lichtleiter in je nach Statusmeldung unterschiedlicher Kombination einer jeweiligen Art von Aktivität oder einer jeweiligen Nichtaktivität einkoppeln.The method according to the invention for providing a status display on a protective switching device (namely in particular an arc protection switch) is characterized in that for providing a plurality of status messages, two light emitting diodes of different color in a light guide in different combination depending on the status message of a respective type of activity or a couple each nonactivity.

Bei dem erfindungsgemäßen Verfahren gibt es somit eine Vielzahl von möglichen Statusmeldungen, und je nach der Anzahl von unterschiedlichen Arten von Aktivität der Leuchtdioden lässt sich die Zahl der Statusmeldungen entsprechend groß gestalten.In the method according to the invention, there are thus a large number of possible status messages, and depending on the number of different types of activity of the LEDs, the number of status messages can be made correspondingly large.

Beispielsweise wird zu zumindest einer Statusmeldung eine Kombination von einer jeweiligen Art von Aktivität für beide Leuchtdioden eingesetzt, bei der sich die beiden Farben der Leuchtdioden zumindest zeitweise mischen. Genauso kann die Anzahl der Statusmeldungen auch dadurch hoch sein, dass in zumindest einer Statusmeldung eine Kombination eingesetzt wird, bei der zumindest eine der Leuchtdioden blinkt. Beispielsweise kann die andere der beiden Leuchtdioden dann gar nicht eingeschaltet werden, konstant leuchten oder im Wechsel mit der anderen Leuchtdiode leuchten.For example, for at least one status message, a combination of a respective type of activity for both LEDs is used, in which the two colors of the Mix LEDs at least temporarily. Equally, the number of status messages can also be high in that a combination is used in at least one status message in which at least one of the LEDs flashes. For example, the other of the two light-emitting diodes can then not be switched on at all, glow constantly or light up in alternation with the other light-emitting diode.

Schließlich ist es noch möglich, dass anstelle eines Blinkens mit gleichlangen Intervallen von Leuchten und Pausen ein solches Blinken verwendet wird, bei dem eine der Leuchtdioden in zwei von vier Intervallen oder zwei von drei Intervallen mit jeweiliger Pause leuchtet, sodass sich weitere Kombinationen ergeben.Finally, it is still possible that, instead of flashing with equal intervals of lights and pauses, such flashing is used in which one of the light emitting diodes illuminates at two out of four intervals or two out of three intervals with respective pauses so that further combinations result.

Ein Lichtbogenschutzschalter hat die Aufgabe, beim Auftreten eines Lichtbogens in einer Schaltung, die entweder in Reihe oder parallel zum Lichtbogenschutzschalter geschaltet ist, einen Stromfluss zu unterbrechen. Er kann zusätzlich die Funktionalität haben, eine Überspannung zu erkennen oder auch einen Fehlerstrom. Weitere Funktionalitäten sind möglich.An arc-protection switch has the task of interrupting a current flow when an arc occurs in a circuit which is connected either in series or in parallel with the arc-proof circuit breaker. It can also have the functionality to detect an overvoltage or a fault current. Further functionalities are possible.

Vorliegend von Interesse ist es, dass ein Lichtbogenschutzschalter 10 eine Leiterplatte 12 mit einer Elektronik zur Erfassung von bestimmten Situationen aufweist, wobei die Leiterplatte 12 mit einer Bicolor-LED 14 bestückt ist, einem Bauteil 14 also, das über zwei verschiedenfarbige Leuchtdioden verfügt, die unabhängig voneinander ansteuerbar sind, aber so nahe aneinander sitzen, dass sie an einen gemeinsamen Lichtbogenleiter 16 angekoppelt werden können, dessen Fuß 18 etwas verbreitert ist, um Licht der Leuchtdioden aufzunehmen. Ein Ende 20 des Lichtbogenleiters 16 tritt an der Vorderseite hervor, vgl. FIG 2. Trotz der Verwendung zweier Leuchtdioden muss auf der Vorderseite nur der Platz für das eine Ende 20 eines einzigen Lichtleiters 16 bereitgestellt sein, so dass der übrige Platz für andere Einrichtungen wie z. B. einen Aufkleber mit Strichcodes für eine Kennung etc. zur Verfügung steht.Of interest here is that an arc protection switch 10, a circuit board 12 with an electronics for detecting of certain situations, wherein the printed circuit board 12 is equipped with a bi-color LED 14, ie a component 14 which has two different colored light-emitting diodes, which are independently controllable, but so close to each other, that they are coupled to a common arc conductor 16 can be, whose foot 18 is slightly widened to receive light from the LEDs. One end 20 of the arc conductor 16 protrudes at the front, cf. FIG. 2 , Despite the use of two light-emitting diodes, only the space for the one end 20 of a single light guide 16 must be provided on the front side, so that the remaining space for other devices such. B. a sticker with barcodes for an identifier, etc. is available.

Es wird nun anhand von FIG 3 erläutert, wie mithilfe der beiden Leuchtdioden aus dem Bauteil 14 fünfzehn unterschiedliche Statusmeldungen abgegeben werden können.It will now be based on FIG. 3 explains how to use the two LEDs from the component 14 fifteen different status messages can be issued.

Die erste Statusmeldung beinhaltet, dass beide Leuchtdioden ausgeschaltet sind. Es gibt daher keine Anzeige. Dies ist der fehlerfreie Zustand.The first status message indicates that both LEDs are switched off. There is therefore no indication. This is the faultless condition.

Die zweite Statusmeldung beinhaltet, dass eine im Beispiel gelbe Leuchtdiode, symbolisiert durch ein "Y", dauerhaft Licht abgibt. Die zweite Leuchtdiode ist hierbei ausgeschaltet, gibt kein Licht ab. Diese Kombination von eingeschalteter erster Leuchtdiode und ausgeschalteter zweiter Leuchtdiode wird beispielsweise dann verwendet, wenn es serielle Störlichtbögen gibt, also Lichtbögen in Reihe zur Last.The second status message indicates that a yellow LED in the example, symbolized by a "Y", permanently emits light. The second LED is switched off, emits no light. This combination of switched-on first light-emitting diode and switched-off second light-emitting diode is used, for example, when there are serial fault arcs, ie arcs in series with the load.

Bei der dritten Statusmeldung ist es umgekehrt: Die zweite Leuchtdiode, welche rotes Licht abgibt (symbolisiert durch ein "R") leuchtet dauerhaft, die erste Leuchtdiode ist ausgeschaltet. Dies ist beispielsweise dann der Fall, wenn es parallele Störlichtbögen gibt, also Lichtbogenkurzschlüsse.In the third status message, it is the other way round: The second LED, which emits red light (symbolized by an "R"), shines permanently, the first LED is switched off. This is the case, for example, when there are parallel arcing faults, ie arc shorts.

Bei der vierten Statusmeldung leuchten beide Leuchtdioden dauerhaft und gleichzeitig. Auf diese Weise mischen sich die beiden Farben Rot und Gelb zur Farbe Orange, symbolisiert durch ein "O". Diese Statusmeldung wird beispielsweise dann abgegeben, wenn eine Überspannung erfasst wird.In the fourth status message, both LEDs light permanently and simultaneously. In this way, the two colors red and yellow mix to the color orange, symbolized by an "O". This status message is given, for example, when an overvoltage is detected.

Bei der fünften Statusmeldung blinkt die erste, gelbe Leuchtdiode gleichmäßig. Es gibt also gleich lange Intervalle des Leuchtens und der Pause. Diese Statusmeldung wird beispielsweise dann abgegeben, wenn ein Selbsttest ergeben hat, dass der Lichtbogenschutzschalter nicht ordnungsgemäß arbeitet.At the fifth status message, the first, yellow LED flashes evenly. So there are equally long intervals of lighting and break. This status message is issued, for example, when a self-test has shown that the arc circuit breaker is not working properly.

Bei der sechsten Statusmeldung blinkt die rote Leuchtdiode auf dieselbe Weise, z. B. zur Angabe der Tatsache, dass ein Fehlerstrom geflossen ist.At the sixth status message the red LED flashes in the same way, eg. B. to indicate the fact that a fault current has flowed.

Weitere Statusmeldungen können bei Überlast und Kurzschluss und vielen weiteren Situationen vorkommen.Other status messages may occur in the event of overload and short circuit and many other situations.

So ist bei der Statusmeldung sieben vorgesehen, dass die gelbe Leuchtdiode regelmäßig blinkt, die rote aber dauerhaft leuchtet. Auf diese Weise erhält man einen Wechsel zwischen Orange und Rot.Thus, in the status message seven, it is provided that the yellow LED flashes regularly, but the red one lights up permanently. In this way you get a change between orange and red.

Bei der achten Statusmeldung ist vorgesehen, dass die gelbe Leuchtdiode dauerhaft leuchtet und die rote Leuchtdiode blinkt, sodass man einen Wechsel zwischen Gelb und Orange erhält.In the eighth status message it is provided that the yellow LED is permanently lit and the red LED flashes, so that a change between yellow and orange takes place.

Bei der Statusmeldung neun blinken beide Leuchtdioden synchron, sodass man ein Blinken in Orange erhält.When status message nine flashes both LEDs synchronously, so you get a flashing in orange.

Bei der Statusmeldung zehn blinken die beiden Leuchtdioden versetzt zueinander, sodass man abwechselnd Gelb und Rot sieht.When the status message is ten, the two LEDs flash offset to each other, so you see alternately yellow and red.

Bei der Statusmeldung elf blinkt die gelbe Leuchtdiode mit halber Frequenz wie bisher, blinkt also einmal und macht dann drei Intervalle Pause. Die rote Leuchtdiode blinkt hingegen regelmäßig mit einem Intervall Blinken, einem Intervall Pause. Man erhält somit ein Blinken mit Orange und Rot abwechselnd.When the status message eleven the yellow LED flashes at half frequency as before, so it flashes once and then makes three intervals break. In contrast, the red LED flashes regularly with an interval blinking, an interval pause. One thus receives a blinking alternately with orange and red.

Genauso lässt sich unter Umkehrung der Rollen der beiden Leuchtdioden bezüglich der Statusmeldung elf ein Blinken zwischen Gelb und Orange als Statusmeldung zwölf erzielen.Similarly, by reversing the roles of the two LEDs with respect to the status message eleven a blink between yellow and orange can be achieved as a status message twelve.

Blinken beide Leuchtdioden asynchron jeweils für eine Periode leuchtend mit drei Perioden Pause, so erhält man die Statusmeldung dreizehn, bei der abwechselnd Gelb und Rot blinkt.If both LEDs are flashing asynchronously, each with a period of three periods pausing for a period, the status message thirteen is displayed, alternately flashing amber and red.

Durchläuft man intervallweise die Zustände gemäß Status 2, 3 und 4, so erhält man den Status vierzehn, bei dem die gelbe Farbe in die orangene übergeht, diese ins Rote und dann wieder ins Gelbe etc.If you go through the states at intervals according to statuses 2, 3 and 4, you get the status fourteen, in which the yellow color changes to the orange, this into red and then back to yellow.

Beim Status fünfzehn wird genau dasselbe getan, aber jeweils eine Pause von einer Intervalllänge eingelegt.At status fifteen, exactly the same thing is done, but one break of one interval length is taken.

Es wurde gezeigt: Dadurch, dass zwei Leuchtdioden Licht in einen einzigen Lichtleiter 16 einkoppeln und in einem Bauteil 14 so nahe aneinander angeordnet sind, dass sie bei gleichzeitigem Leuchten eine Mischfarbe (vorliegend Orange) ergeben, wird eine Vielzahl von Statusmeldungen ermöglicht. Dies gilt insbesondere, wenn unterschiedliche Arten des Blinkens zusätzlich ermöglicht sind.It has been shown that two light-emitting diodes couple light into a single optical waveguide 16 and are arranged in a component 14 so close together that they produce a mixed color (in the present case orange) when illuminated, thereby enabling a large number of status messages. This is especially true when different types of flashing are additionally enabled.

Die Erfindung kann neben einem Lichtbogenschutzschalter mit zusätzlichen Funktionalitäten auch bei anderen Schutzschaltgeräten, beispielsweise einem Fehlerstromschutzschalter, einem Leitungsschutzschalter oder einem Leistungsschalter oder dergleichen eingesetzt werden. Sie ist insbesondere dann vorteilhaft, wenn solche Schutzschaltgeräte über eine Vielzahl von Funktionalitäten verfügen, die mit einer hohen Anzahl an benötigten Statusmeldungen einhergehen.The invention can be used in addition to an arc circuit breaker with additional functionalities in other protection devices, such as a residual current circuit breaker, a circuit breaker or a circuit breaker or the like. It is particularly advantageous when such protection devices have a variety of functionalities that go hand in hand with a high number of required status messages.
