Abstract

A power circuit breaker (2) comprises break contacts for main current circuits and a connection device (6) for auxiliary current circuits that interacts with a contact device (7) mounted in a fixed manner. Signaling switches (13) are placed on a withdrawable rack (1), which accommodates the power circuit breaker (2), and are provided for detecting and signaling the position of the power circuit breaker (2) located inside said withdrawable rack (1). The signaling switches (13) are structurally assigned in a direct manner to an interface subassembly (14) that processes signals, which are transmitted out of the contact device (7) and by the signaling switches (13) and to be relayed to a field bus system (12).

Description

Die Erfindung betrifft einen elektrischen Leistungsschalter mit Trennkontakten für Hauptstromkreise, einer Anschlussvorrichtung für Hilfsstromkreise und mit einer mit der Anschlussvorrichtung zusammenwirkenden ortsfest angebrachten Kontaktvorrichtung, wobei der Leistungsschalter bezüglich der Trennkontakte eine Betriebsstellung und eine Trennstellung sowie eine dazwischen liegende Teststellung einnehmen kann und die Anschlussvorrichtung für Hilfsstromkreise in der Betriebsstellung und in der Teststellung mit der ortsfesten Kontaktvorrichtung verbunden ist und wobei ferner an einem den Leistungsschalter aufnehmenden Einschubrahmen Meldeschalter zur Erfassung und Signalisierung der genannten Stellungen des Leistungsschalters im Einschubrahmen und eine Schnittstellenbaugruppe angeordnet sind, welche aus der Kontaktvorrichtung und von den Meldeschaltern übertragene Signale zur Weitergabe an ein Feldbus-System verarbeitetThe invention relates to an electrical circuit breaker with isolating contacts for main circuits, a connection device for auxiliary circuits and with a cooperating with the terminal stationary mounted contact device, the circuit breaker with respect to the isolating contacts can occupy an operating position and a disconnected position and an intermediate test position and the connecting device for auxiliary circuits in the operating position and in the test position is connected to the stationary contact device and further arranged on a circuit breaker receiving frame signaling switch for detecting and signaling the said positions of the circuit breaker in the drawer frame and an interface module, which from the contact device and the signal switches transmitted signals to Transfer to a fieldbus system processed

Einschub-Leistungsschalter dieser Art (engl. withdrawable or drawout circuit breaker) werden zumeist in Verbindung mit Einschubrahmen benutzt, die als Träger ortsfester Trennkontakte und der erwähnten ortsfesten Kontaktvorrichtung ausgebildet sind. Beispiele solcher Anordnungen sind der US 4 139 748 , US 4 743 715 und US 5 594 221 zu entnehmen. Über die Kontaktvorrichtung wird eine Vielzahl von Signalen übertragen, und zwar sowohl von dem bewegbaren Leistungsschalter zu dem Einschubrahmen als auch umgekehrt. Wesentlich ist dabei insbesondere eine Signalisierung der Position des Leistungsschalters im Einschubrahmen (Betriebsstellung, Teststellung, Trennstellung), um den Schaltzustand und die Betriebsbereitschaft der Leistungsschalter einer Schaltanlage mittels einer zentralen Betriebswarte überwachen zu können. Zur Erfassung der Position des Leistungsschalters werden spezielle, robuste und besonders betriebssichere Baugruppen von Meldeschaltern eingesetzt, z.B. nach DE 201 05 889 U1 . Diese Melde- oder Hilfsschalterbaugruppe befindet sich an einer Seitenwand eines Einschubrahmens und wird durch einen im Einschubrahmen befindlichen Leistungsschalter betätigt. Damit wird auch der Zustand erfasst, dass sich kein Leistungsschalter im Einschubrahmen befindet.Plug-in circuit breakers of this type (withdrawable or drawout circuit breakers) are mostly used in conjunction with slide-in frames, which are designed as carriers of fixed isolating contacts and the mentioned stationary contact device. Examples of such arrangements are the US 4,139,748 . US 4,743,715 and U.S. 5,594,221 refer to. Via the contact device, a plurality of signals is transmitted, both from the movable circuit breaker to the drawer frame and vice versa. It is essential in particular a signaling of the position of the circuit breaker in the drawer frame (operating position, test position, Isolated position) to monitor the switching state and the operational readiness of the circuit breaker of a switchgear by means of a central control room. To detect the position of the circuit breaker special, robust and highly reliable modules of signaling switches are used, for example DE 201 05 889 U1 , This signaling or auxiliary switch assembly is located on a side wall of a slide-in frame and is actuated by a power switch located in the withdrawable frame. This also detects the condition that there is no circuit breaker in the withdrawable rack.

Zum Austausch von Steuersignalen zwischen einer zentralen Steuereinrichtung und den Leistungsschaltern einer Schaltanlage ist es zur Vermeidung einer kompletten Einzelverdrahtung mit zahlreichen Leitern bekannt, sogenannte Feldbus-Systeme zu verwenden, die im einfachsten Fall unabhängig von der Anzahl zu vernetzender Schaltgeräte mit vier Adern (zwei Signaladern, zwei Adern für die Stromversorgung) auskommen. Beispiele für die Anwendung von Feldbus-Systemen sind in der DE 197 06 961 A1 oder der EP 0 736 946 B1 beschrieben. In ein solches Feldbus-System sind daher einerseits Meldungen und Befehle zwischen dem Schutzmodul (elektronischer Überstromauslöser) und einer Warte oder Zentrale einzuspeisen sowie die Positionsmeldungen des Leistungsschalters im Einschubrahmen. Da aber der Austausch aller Informationen über ein Schnittstellenmodul (Interface-Baugruppe; Gateway) erfolgt, bedeutet dies, dass zumindest innerhalb der Einschubrahmen/Leistungsschalter-Baugruppe das Schnittstellenmodul mit dem Schutzmodul und der Meldeschalterbaugruppe durch eine direkte (1:1) Verdrahtung zu verbinden ist, wie dies in der EP 0 923 175 A1 beschrieben ist. Dabei befinden sich die Meldeschalter an der (dem Leistungsschalter zugewandten) Innenseite einer Seitenwand des Einschubrahmens, wahrend das Schnittstellenmodul an der gegenüberliegenden Außenseite angebracht ist. Gemeinsame Befestigungsmittel für die Meldeschalter und das Schnittstellenmodul durchsetzen die Seitenwand.For the exchange of control signals between a central control device and the circuit breakers of a switchgear it is known to avoid a complete single wiring with numerous conductors to use so-called fieldbus systems, in the simplest case, regardless of the number to be networked switching devices with four wires (two signal wires, two wires for the power supply). Examples of the application of fieldbus systems are in the DE 197 06 961 A1 or the EP 0 736 946 B1 described. In such a fieldbus system, therefore, messages and commands between the protection module (electronic overcurrent release) and a control room or control center are fed in as well as the position messages of the circuit breaker in the withdrawable rack. However, since the exchange of all information takes place via an interface module (interface module, gateway), this means that at least within the withdrawable rack / circuit breaker module, the interface module with the protection module and the signaling switch assembly is to be connected by a direct (1: 1) wiring like this in the EP 0 923 175 A1 is described. The signaling switches are located on the (facing the circuit breaker) Inside a side wall of the drawer frame, while the interface module is mounted on the opposite outside. Common fasteners for the signaling switches and the interface module pass through the side wall.

Der Erfindung liegt die Aufgabe zugrunde, den Aufwand für Verdrahtung und Befestigung der beschriebenen Komponenten zu verringern und dabei kompakte Gesamtabmessungen zu ermöglichen.The invention has for its object to reduce the cost of wiring and attachment of the components described while allowing compact overall dimensions.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass die Kontaktvorrichtung, die Schnittstellenbaugruppe und die Meldeschalter zu einer Baueinheit kombiniert sind. Damit verkürzt sich die Verdrahtung derart, dass sie keinen Einfluss auf die Gesamtabmessungen mehr hat, wodurch zugleich der Materialaufwand verringert und die Betriebssicherheit gesteigert ist. In diesem Fall kann eine konventionelle Verdrahtung vollständig entfallen, da beispielsweise eine einzige Leiterplatte zugleich Träger der Schnittstellenbaugruppe, der Kontaktvorrichtung und der Meldeschalter sein kann.According to the invention, this object is achieved in that the contact device, the interface module and the signaling switch are combined to form a structural unit. This shortens the wiring in such a way that it has no influence on the overall dimensions, which at the same time reduces the material expenditure and increases the reliability. In this case, a conventional wiring can be completely eliminated, since, for example, a single circuit board can also be the carrier of the interface assembly, the contact device and the signaling switch.

Die Erfindung wird im folgenden anhand des in der Figur veranschaulichten Ausführungsbeispieles näher erläutert. Die Figur zeigt in schematischer Darstellung die zusammenwirkenden Baugruppen des Leistungsschalters und des Einschubrahmens in Verbindung mit einem Feldbus-System.The invention will be explained in more detail below with reference to the embodiment illustrated in the figure. The figure shows a schematic representation of the cooperating modules of the circuit breaker and the slide-in frame in conjunction with a fieldbus system.

Die Figur zeigt als zusammenwirkende Einheiten einen Einschubrahmen 1 mit einem darin eingesetzten Niederspannungs-Leistungsschalter 2. Der Aufbau dieser Einheiten im Einzelnen ist im vorliegenden Zusammenhang unwesentlich, weshalb von näheren Darlegungen abgesehen wird. Es sei lediglich darauf hingewiesen, dass ein Einschubrahmen in DE 201 05 889 U1 dargestellt ist und dass Niederspannungs-Leistungsschalter einer geeigneten Bauform gleichfalls dem Fachmann vertraut sind.The figure shows as cooperating units a drawer frame 1 with a low-voltage circuit breaker 2 inserted therein. The structure of these units in detail is immaterial in the present context, which is why details will be omitted. It should be noted that a slide-in frame in DE 201 05 889 U1 is shown and that low-voltage circuit breakers of a suitable design are also familiar to the expert.

Angedeutet ist in der Figur ein zu dem Leistungsschalter 2 gehörender elektronischer Überstromauslöser 3, ein Betätigungsmagnet 4 zum Ausschalten und eine weiterer, zum Einschalten des Leistungsschalters 2 dienender Betätigungsmagnet 5. In bekannter Weise sorgen die Betätigungsmagnete 4 und 5 für eine Freigabe von Verklinkungsteilen in der Schaltmechanik des Leistungsschalters, um die gewünschten Schaltvorgänge zu ermöglichen. Die genannten Einheiten, elektronischer Überstromauslöser 3, Betätigungsmagnete 4 und 5 sind mit einer Anschlussvorrichtung 6 verbunden, die in bekannter Weise am Leistungsschalter 2 derart angebracht ist, dass sie mit einer am Einschubrahmen 1 befindlichen Kontaktvorrichtung 7 in Eingriff gelangen kann. Diese gehört zu einer Baueinheit 10, die Anschlussmittel 11 für ein Feldbus-System 12 (Profibus, Interbus) aufweist, welches zur Kommunikation zwischen mehreren Einheiten der gezeigten Art untereinander und mit einer Betriebszentrale oder Warte dient. Die Baueinheit 10 enthält ferner eine Meldeschalterbaugruppe 13 zur Erfassung der Anwesenheit eines Leistungsschalters 2 im Einschubrahmen 1 sowie der jeweiligen Position (Trenn-, Test- oder Betriebsstellung). Eine gleichfalls zu der Baueinheit 10 gehörende Schnittstellenbaugruppe 14 verknüpft die Kontaktvorrichtung 7, die Meldeschalterbaugruppe 13 und das Feldbus-System 12. Da die genannten Baugruppen im enger räumlicher Nachbarschaft angeordnet sind, entfällt eine gesonderte Verdrahtung, wie sie bisher erforderlich war.In the figure, an electronic overcurrent release 3 belonging to the circuit breaker 2, an actuating magnet 4 for switching off and another actuating magnet 5 serving for switching on the circuit breaker 2 are indicated. In a known manner, the actuation magnets 4 and 5 ensure release of latching parts in the switching mechanism of the circuit breaker to allow the desired switching operations. Said units, electronic overcurrent release 3, actuating magnets 4 and 5 are connected to a connection device 6 which is mounted in a known manner on the circuit breaker 2 such that it can engage with a contact frame 7 located on the contact device 7 in engagement. This belongs to a module 10, which has connection means 11 for a fieldbus system 12 (Profibus, Interbus), which is used for communication between a plurality of units of the type shown with each other and with an operation center or control room. The assembly 10 further includes a signaling switch assembly 13 for detecting the presence of a circuit breaker 2 in the drawer frame 1 and the respective position (separation, test or operating position). An interface module 14, which likewise belongs to the assembly 10, links the contact device 7, the signaling switch assembly 13 and the fieldbus system 12. Since the assemblies mentioned are arranged in close spatial proximity, a separate wiring, which was previously required, is dispensed with.

Mittels eines gestrichelten Pfeiles ist angedeutet, dass die Schnittstellenbaugruppe 14 auch weitere Signale, z. B. von anderen gleichen oder ähnlichen Baueinheiten, empfangen und verarbeiten kann, die über ein Kommunikationssystem 15 übertragen werden. Ferner ist durch Verbindungen zwischen der Kontaktvorrichtung 7 und der Schnittstellenbaugruppe 14 angedeutet, dass der Überstromauslöser 3 sowie die Betätigungsmagnete 4 und 5 sowohl mittels des Feldbus-Systems 12 als auch mittels des Kommunikationssystems 15 beeinflusst werden können. Auf diese Weise kann beispielsweise der Leistungsschalter durch Fernsteuerung ein- oder ausgeschaltet werden oder es können Ansprechwerte des Überstromauslösers 3 verändert werden. Dabei wird durch die jeweils zuvor übermittelte Positionsmeldung des Leistungsschalters 2 (nicht vorhanden oder vorhanden und in Position Trenn/Test/Betrieb) sichergestellt, dass nur ausführbare Befehle bzw. nur dann Befehle übermittelt werden, wenn der Betriebszustand des Leistungsschalters eine Verarbeitung der Befehle zulässt.By means of a dashed arrow is indicated that the interface assembly 14 and other signals, eg. B. from other identical or similar units that can be received and processed, which are transmitted via a communication system 15. Furthermore, it is indicated by connections between the contact device 7 and the interface module 14 that the overcurrent release 3 and the actuating magnets 4 and 5 can be influenced both by means of the field bus system 12 and by means of the communication system 15. In this way, for example, the circuit breaker can be switched on or off by remote control or it can response values of the overcurrent release 3 can be changed. In this case, it is ensured by the respective previously transmitted position message of the circuit breaker 2 (not present or present and in position separation / test / operation) that only executable instructions or only commands are transmitted when the operating state of the circuit breaker allows processing of the commands.

Die Darstellung in der Figur ist bezüglich der Kontaktvorrichtung 7 insofern vereinfacht, als die Anzahl der einzelnen Kontaktstellen auf die zum Verständnis der Erfindung benötigten Kanäle beschränkt ist. In der Praxis können Niederspannungs-Leistungsschalter eine sehr viel größere Anzahl von Kontaktstellen in der Kontaktvorrichtung aufweisen, die im Sinne der Erfindung gleichfalls Bestandteil der Baueinheit 10 sein können.The illustration in the figure is simplified with respect to the contact device 7 in that the number of individual contact points is limited to the channels required for understanding the invention. In practice, low-voltage circuit breakers may have a much larger number of contact points in the contact device, which may also be part of the assembly 10 within the meaning of the invention.
