Elektrischer Leistungsschalter mit einem InformationsspeicherElectrical circuit breaker with an information store
Die Erfindung betrifft einen elektrischen Leistungsschalter mit folgenden Merkmalen:The invention relates to an electrical circuit breaker with the following features:
- eine elektromechanische Baugruppe mit wenigstens einem Schaltkontakt, einer den Schaltkontakt betätigenden Antriebsvorrichtung und zugehörigen Verklinkungseinrichtungen zur Freigabe von Kraftspeichern zum Schließen und Öffnen des Schaltkontaktes,an electromechanical assembly with at least one switch contact, a drive device actuating the switch contact and associated latching devices for releasing force stores for closing and opening the switch contact,

- ein elektronischer Uberstromausloser zur Verarbeitung eines Signales des Stromsensors und zur Abgabe eines Signales zur- An electronic overcurrent release for processing a signal from the current sensor and for emitting a signal for
Freigabe der Verklinkungseinrichtung für das Öffnen des Schaltkontaktes,Release of the latching device for opening the switching contact,
- eine bewegliche Verbindungsleitung zur Verbindung des Stromwandlers mit dem Uberstromausloser und - ferner mit einem Informationsspeicher zur Übergabe von Eigenschaftskennwerten des Stromwandlers und/oder der elek- tromechanischen Baugruppe des Leistungsschalters an den Uberstromausloser.- A movable connecting line for connecting the current transformer to the overcurrent release and - furthermore with an information store for transferring characteristic values of the current transformer and / or the electromechanical assembly of the circuit breaker to the overcurrent release.
Ein Leistungsschalter mit den genannten Merkmalen ist beispielsweise durch die WO 97/08725 bekannt geworden. Hierbei befindet sich der Informationsspeicher an der Außenseite des Gehäuses des Überstromauslösers und ist an diesem lösbar angebracht. Durch die Anbringung des Informationsspeichers an dem Uberstromausloser wird erreicht, daß in eine Prüfung eines Überstromauslösers nach dessen Entfernung aus dem Leistungsschalter auch der Informationsspeicher einbezogen und auch dessen eventuelle Fehler erfaßt werden. Bei dieser Vorgehensweise wird davon ausgegangen, daß bei einem Austausch der Stromwandler des Leistungsschal ters auch der Informationsspeicher aus zutauschen bzw . seine Programmierung anzupassen ist . Ahnliche Maßnahmen erfordert eine Anordnung nach EP 0 493 272 Bl , bei der eine schalterfeste Interfacekarte vorgesehen ist , mit der einerseits die Stromwandler und andererseits der Uberstromausloser zu verbinden ist .A circuit breaker with the features mentioned has become known, for example, from WO 97/08725. Here, the information store is located on the outside of the housing of the overcurrent release and is detachably attached to it. The attachment of the information store to the overcurrent release ensures that the information store is also included in a test of an overcurrent release after it has been removed from the circuit breaker, and that any faults are also detected. This procedure assumes that an exchange the current transformer of the circuit breaker also replace the information storage or. its programming needs to be adjusted. Similar measures require an arrangement according to EP 0 493 272 B1, in which a switch-resistant interface card is provided, with which the current transformers on the one hand and the overcurrent release on the other hand are to be connected.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, das richtige Zusammenwirken zwischen den Stromwandlern und dem Uberstromausloser auf einfachste Weise sicherzustel len .In contrast, the invention is based on the object of ensuring the correct interaction between the current transformers and the overcurrent release in the simplest way.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Informationsspeicher Bestandteil einer an der Verbindungsleitung angebrachten ersten Komponente einer zweiteili- gen Steckvorrichtung ist, deren zweite Komponente zum Uberstromausloser gehört . Durch den Einbau der Stromwandler in den Leistungsschalter oder den späteren Austausch der Stromwandler wird auf diese Weise der Nenn- oder Bemessungsstrom des Leistungsschalters festgelegt . Zugleich kann dieser In- formationsspeicher dazu dienen, weitere Eigenschaftskennwerte festzulegen, wie z . B . die Schaltleistungsklasse oder die Normenklasse des Leistungsschalters . Hierbei ist unter Schaltleistungsklasse eine Bemessung der elektromechanischen Baugruppe entsprechend einem bestimmten geforderten Schalt- vermögen, das in kA angegeben wird, zu verstehen . Als Normenklasse wird im vorliegenden Zusammenhang eine Aus legung gemäß bestimmten regionalen Regelwerken verstanden, wie sie insbesondere für den IEC-Markt, den ANSI-Markt oder den UL-Markt gelten . Es sei ferner erwähnt, daß im vorliegenden Zusammen- hang als Eigenschaftskennwert eine Kombination eines bestimmten Parameters , z . B . Bemessungsstrom, mit einem Wert des Bemessungsstroms bezeichnet wird .This object is achieved according to the invention in that the information store is part of a first component of a two-part plug-in device attached to the connecting line, the second component of which belongs to the overcurrent release. By installing the current transformers in the circuit breaker or later exchanging the current transformers, the rated or rated current of the circuit breaker is determined in this way. At the same time, this information store can be used to define further characteristic values, such as. B. the switching capacity class or the standard class of the circuit breaker. Switching power class means a dimensioning of the electromechanical assembly according to a certain required switching capacity, which is specified in kA. In the present context, a standard class is understood to mean an interpretation based on certain regional regulations, such as those that apply in particular to the IEC market, the ANSI market or the UL market. It should also be mentioned that in the present context a combination of a certain parameter, e.g. B. Rated current, is designated with a value of the rated current.
Da bekanntlich Widerstände zu den zuverlässigsten und ein- fachsten elektrischen Bauelementen gehören, erscheint es vor- teilhaft, den Informationsspeicher durch Widerstände zu bilden. Zweckmäßig können diese Widerstände zwischen Kontaktstifte der ersten Komponente der Steckvorrichtung geschaltet sein. Sind beispielsweise vier Eigenschaftskennwerte zu ko- dieren, z. B. der Bemessungsstrom des Leistungsschalters, seine Baugröße, die Schaltleistungsklasse und die Normenklasse, so kann hierfür je ein Widerstand vorgesehen sein, dessen Widerstandswert zwischen etwa 1 Ω und etwa 1 MΩ liegt, wobei den Widerstandswerten festgelegte Stufen der ge- nannten Eigenschaftskennwerte zugewiesen sind. Innerhalb der genannten Spanne von Widerstandswerten lassen sich auf diese Weise fehlerfrei beispielsweise 16 unterschiedliche Werte festlegen.Since it is well known that resistors are among the most reliable and simple electrical components, it appears partial to form the information store through resistors. These resistors can expediently be connected between contact pins of the first component of the plug device. If, for example, four characteristic property values are to be coded, e.g. If, for example, the rated current of the circuit breaker, its size, the switching power class and the standard class, a resistor can be provided for each, the resistance value of which lies between approximately 1 Ω and approximately 1 MΩ, with the resistance values being assigned levels of the named characteristic values. In this way, for example, 16 different values can be defined without error within the stated range of resistance values.
Sofern nur eine beschränkte Anzahl von Eigenschaftskennwerten zu speichern ist, kann dies nach einer weiteren Ausgestaltung der Erfindung dadurch geschehen, daß nur ein einzelner Widerstand vorgesehen ist, dessen Widerstandswert eine vorbestimmte Kombination von Eigenschaftskennwerten repräsentiert.If only a limited number of property characteristic values are to be stored, this can be done according to a further embodiment of the invention in that only a single resistor is provided, the resistance value of which represents a predetermined combination of property characteristic values.
Die Erfindung wird im folgenden anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to the embodiment shown in the figure.
In der Figur sind schematisch in einpoliger Darstellung die Hauptkomponenten eines Niederspannungs-Leistungsschalters gezeigt. Dabei stellt die gestrichelte äußere Kontur den Leistungsschalter 1 als Ganzes dar. Im Inneren befindet sich ein Schaltkontakt 2 und eine mit diesem zusammenwirkende Antriebsvorrichtung 3. Zu dieser gehören nicht dargestellte Fe- derspeicher und Verklinkungen, die von Hand oder ferngesteuert betätigbar sind, um den Schaltkontakt 2 zu schließen bzw. zu öffnen. Ferner gehört zu dem Leistungsschalter 1 ein elektronischer Uberstromausloser 4, der in bekannter Weise eine Schutzeinrichtung bildet, um den Schaltkontakt 2 beim Vorlie- gen vorbestimmter Bedingungen zu öffnen. Hierzu ist der Über- stromausloser 4 durch eine bewegliche Verbindungsleitung 5 mit einem Stromwandler 6 verbunden und erhält eine zur Auswertung erforderliche Hilfsenergie entweder gleichfalls aus dem Stromwandler 5 oder aus einem in dem gezeigten Beispiel zusatzlich vorgesehenen Energiewandler 7. Je nach der Polzahl des Leistungsschalters 1 sind ein oder mehrere Stromwandler 6 und ggf. Energiewandler 7 vorhanden.In the figure, the main components of a low-voltage circuit breaker are shown schematically in a single-pole representation. The dashed outer contour represents the circuit breaker 1 as a whole. Inside there is a switch contact 2 and a drive device 3 which interacts with it. This includes spring retainers and latches (not shown) which can be actuated by hand or by remote control around the switch contact 2 to close or open. Furthermore, the circuit breaker 1 includes an electronic overcurrent release 4, which in a known manner forms a protective device in order to open the switch contact 2 when predetermined conditions are present. For this the Current-free 4 connected to a current transformer 6 by a movable connecting line 5 and receives an auxiliary energy required for evaluation either likewise from the current transformer 5 or from an energy converter 7 additionally provided in the example shown. Depending on the number of poles of the circuit breaker 1, one or more current transformers 6 are and possibly energy converter 7 available.
Am Ende der biegsamen Leitung 5 ist eine erste Komponente 10 einer zweiteiligen Steckvorrichtung angebracht, deren zugehörige zweite Komponente 11 sich an dem Uberstromausloser 4 befindet. Die Komponente 10 bildet zugleich einen Informationsspeicher für wichtige Eigenschaftskennwerte des Leistungsschalters 1. Hierzu sind entsprechend bemessene Widerstände zwischen benachbarte Kontaktstifte der Komponente 10 geschaltet, wie dies näher in der Figur 2 gezeigt ist. Jeder der vier gezeigten Widerstände 12, 13, 14 und 15 entspricht hierbei einem bestimmten Parameter, z. B. Bemessungsstrom, Schaltleistungsklasse oder Normenklasse. Demgegenüber wird in der Ausführung der Komponente 10 der Steckvorrichtung gemäß der Figur 3 anstelle der Widerstände 12, 13, 14 und 15 nur ein einzelner Widerstand 16 benutzt. Dieser repräsentiert eine bestimmte Kombination von Eigenschaftskennwerten, was sich in vielen Fällen als ausreichend erweist und somit eine besonders einfache Art der Kodierung darstellt. Die Auswertung des Widerstandes 16 kann mittels eines einfachen Hilfsprogramms im Uberstromausloser 4 erfolgen. Dies kann beispielsweise so geschehen, daß ein im Uberstromausloser 4 enthaltener Festwertspeicher eine tabellarische Zuordnung von Widerstandswerten des Widerstandes 16 enthält, die bei bestehender Verbindung des Stromwandlers 6 mit dem Uberstromausloser 4 und dessen Aktivierung ausgelesen und in Steuersignale zur Programmierung der im Uberstromausloser enthaltenen Mikroprozessoreinrichtung umgesetzt wird. Aus Gründen einer zuverlässigen Auswertung der Widerstände durch eine Logikschaltung innerhalb des elektronischen Überstromauslösers 4 empfiehlt es sich, als Grenzwerte für den Widerstandswert der Widerstände 12 bis 16 lΩ und 1MΩ zu wählen. Dieser Bereich von Widerständen läßt sich beispielsweise in 16 Werte gliedern, die fehlerfrei erkannt werden. At the end of the flexible line 5, a first component 10 of a two-part plug device is attached, the associated second component 11 of which is located on the overcurrent release 4. Component 10 also forms an information store for important property characteristic values of circuit breaker 1. For this purpose, appropriately dimensioned resistors are connected between adjacent contact pins of component 10, as is shown in more detail in FIG. Each of the four resistors 12, 13, 14 and 15 shown corresponds to a specific parameter, e.g. B. Rated current, switching power class or standard class. In contrast, in the embodiment of component 10 of the plug device according to FIG. 3, only a single resistor 16 is used instead of resistors 12, 13, 14 and 15. This represents a certain combination of characteristic values, which in many cases proves to be sufficient and thus represents a particularly simple type of coding. Resistor 16 can be evaluated using a simple auxiliary program in overcurrent release 4. This can happen, for example, in such a way that a read-only memory contained in the overcurrent release 4 contains a tabular assignment of resistance values of the resistor 16, which are read out when the current transformer 6 is connected to the overcurrent release 4 and its activation, and are converted into control signals for programming the microprocessor device contained in the overcurrent release . For reasons of reliable evaluation of the resistors by a logic circuit within the electronic overcurrent release 4, it is advisable to select 12 to 16 lΩ and 1MΩ as the limit values for the resistance value of the resistors. This range of resistances can be divided, for example, into 16 values that are recognized without errors.
