Description

Beschreibungdescription
Kommunikationsfähiges Schütz mit elektronisch gesteuertem AntriebCommunication-capable contactor with electronically controlled drive
Die Erfindung betrifft Schaltgeräte, insbesondere Relais und/oder Schütze mit einem Magnetsystem, das Anker und Joch, eine Spule mit Spulenkörper und eine Regel- und/oder Steuereinrichtung umfaßt, bei der eine Istwerterfassung antriebs- spezifischer Schaltparameter durch Sensoren erfolgt.The invention relates to switching devices, in particular relays and / or contactors with a magnet system which includes armatures and yokes, a coil with a coil body and a regulating and / or control device in which actual value acquisition of drive-specific switching parameters is carried out by sensors.
Schaltgeräte mit Magnetsystem, z. B. Schütze, werden in der Antriebs- und Automatisierungstechnik eingesetzt und dienen im Verbund mit anderen Komponenten zur Sicherung und Steue- rung elektrischer Verbraucher.Switchgear with a magnet system, e.g. Contactors, for example, are used in drive and automation technology and are used in conjunction with other components to secure and control electrical consumers.
Um solche Schaltgeräte optimal an ihre Schaltaufgabe unter Berücksichtigung unterschiedlicher Betriebsbedingungen und spezifischer Geräteeigenschaften anzupassen, wurden Prinzi- pien geregelter Schaltantriebe entwickelt, die die Typenvielfalt der Spulen, die aufgrund unterschiedlicher Erregerspan- nung bisher notwendig waren, reduziert. Sie sind sowohl für Wechsel- als auch Gleichstrom einsetzbar und führen durch Verringerung des Kontaktprellens zu einer Reduzierung des Ab- brandes der Kontaktstellen und damit zu einer Erhöhung der Kontaktlebensdauer . Gleichzeitig wird die Leistungsaufnahme des Erregerkreises während der Haltephase reduziert.In order to optimally adapt such switching devices to their switching task, taking into account different operating conditions and specific device properties, the principles of controlled switching drives were developed that reduced the variety of types of coils that were previously necessary due to different excitation voltages. They can be used for both alternating and direct current and, by reducing the amount of contact bounce, reduce the burn-off of the contact points and thus increase the contact life. At the same time, the power consumption of the excitation circuit is reduced during the holding phase.
So ist durch die EP 0 376 493 AI eine Steuerschaltung be- kannt, die bei elektromagnetischen Ventilen Prellerscheinungen vermindert. In der ersten Bewegungsphase wird für eine hohe Anzugsgeschwindigkeit ein hoher Strom zugelassen, der noch vor dem Schließen des Ventils auf einen relativ kleinen Wert reduziert wird. Die DE-OS 30 47 488 AI beschreibt neben einer Spulenstromregelung eine Induktionsregelung mit einer im Joch angeordneten Hallsonde, die ebenfalls am Anfang der Bewegungsphase einen erhöhten Spulenstrom, der nach einer vorgegebenen Zeit auf einen Wert reduziert wird, der gerade noch die zum Halten des angezogenen Ankers notwendige Kraft erzeugt. Die DE-OS 44 30 867 AI beschreibt die Regelung eines Schaltgeräteantriebs, der die Einhaltung optimaler Kontaktgeschwindigkeiten und die Begrenzung der Ankerkernstoßgeschwindigkeit über die gesamte Lebensdauer unter Berücksichtigung der Störgrößen wie Abbrand und Toleranzen gewähr- leistet.A control circuit is known from EP 0 376 493 AI which reduces bouncing phenomena in electromagnetic valves. In the first movement phase, a high current is permitted for a high tightening speed, which is reduced to a relatively small value even before the valve is closed. DE-OS 30 47 488 AI describes in addition to a coil current control, an induction control with a Hall probe arranged in the yoke, which also produces an increased coil current at the beginning of the movement phase, which after a predetermined time is reduced to a value that just generates the force required to hold the attracted armature. DE-OS 44 30 867 AI describes the control of a switching device drive, which ensures compliance with optimal contact speeds and the limitation of the armature core impact speed over the entire service life, taking into account the disturbance variables such as erosion and tolerances.
Durch die bekannten Schaltungsanordnungen für Schaltgeräteantriebe werden zwar die Lösungen der obengenannten Probleme angestrebt, es wird aber dabei nicht auf anwenderspezifische Probleme eingegangen, wie z. B. Wartungsfreundlichkeit , EMV- Sicherheit und Bedienungsfreundlichkeit im Alltagseinsatz der Schaltgeräte.The known circuit arrangements for switching device drives are aimed at solving the above-mentioned problems, but it does not address user-specific problems, such as e.g. B. Ease of maintenance, EMC safety and ease of use in everyday use of the switchgear.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsan- Ordnung für Schaltgeräteantriebe zu schaffen, die die eingangs erwähnten Vorteile als auch eine Wartungε- und Bedienungsfreundlichkeit und gleichzeitige EMV-Sicherheit in der täglichen Praxis beinhaltet.The invention has for its object to provide a circuit arrangement for switching device drives, which includes the advantages mentioned above as well as ease of maintenance and operation and simultaneous EMC safety in daily practice.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß Regel- und/oder Steuereinrichtung und Sensoren sich in und/oder an dem Spulenkörper befinden. Unter Regel- und/oder Steuereinrichtung wird im weiteren Verlauf der Beschreibung die Schaltgeräteansteuerelektronik und/oder die Kommunikationse- lektronik verstanden. Durch den kompakten Aufbau des Spulenkörpers, der sämtliche Sensoren, Regel- und/oder Steuereinrichtungen und Anschlüsse enthält, sind herkömmliche Spulenkörper einfach zu ersetzen. Datenbusverbindungen zur Leitstelle vereinfachen durch Rückmeldungen des Schaltgerätes die Prozeßüberwachung (Meldung „Ein-Aus", Steuerspannung steht an, Meldung des Zustandes eines anderen Gerätes, Restlebensdauer der Hauptkontakte) . Außerdem ist eine Parametrierung des Schaltgerätes von der Leitstelle aus möglich.The object is achieved in that the regulating and / or control device and sensors are located in and / or on the coil former. In the further course of the description, regulating and / or control device is understood to mean the switching device control electronics and / or the communication electronics. Due to the compact construction of the coil body, which contains all sensors, regulating and / or control devices and connections, conventional coil bodies are easy to replace. Data bus connections to the control center simplify process monitoring by means of feedback from the switching device ("On-Off" message, control voltage is present on, notification of the status of another device, remaining service life of the main contacts). The switchgear can also be parameterized from the control center.
Zusätzliche vorteilhafte Ausgestaltungen des Erfindungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen. Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert .Additional advantageous embodiments of the subject matter of the invention can be found in the further subclaims. An embodiment of the invention is explained below with reference to a drawing.
Die Zeichnung zeigt eine prinzipielle Darstellung des Ma- gnetsystems als U-Kern ausgeführt, mit Joch 1, Anker 2 und Spulenkörper 3 in einer Explosionsdarstellung. Dabei sind Joch 1 und Anker 2 baugleich mit bisherigen Ausführungsfor- men. Der Spulenkörper 3 setzt sich zusammen aus einer Spule 4, einem Magnetfeldsensor 5, der sich an einem Steg 6 über den mit dem Zwangsluftspalt 7 ausgeführten Schenkel 8 des Jochs 1 vorgesehenen Durchstecköffnung 9 des Spulenkörpers 3 befindet, einer Schützansteuerelektronik 10 und einer darauf gesteckten Kommunikationselektronik 11 mit einem Busanschluß 12, Anschlüssen für die Steuerspannung 13, Hilfsschalter 14 für Schaltstellungsanzeigen des Schützes, Temperatursensoren 15 in der Elektronik 10, 11 , der Spule 4 und einen digitalen Eingang 16 für Meldungen von anderen Schaltgeräten.The drawing shows a basic representation of the magnetic system as a U-core, with yoke 1, armature 2 and coil body 3 in an exploded view. The yoke 1 and armature 2 are identical in construction to previous designs. The coil former 3 is composed of a coil 4, a magnetic field sensor 5, which is located on a web 6 via the leg 8 of the yoke 1 provided with the forced air gap 7, a contactor control electronics 10 and communication electronics 11 plugged thereon with a bus connection 12, connections for the control voltage 13, auxiliary switch 14 for switching position indicators of the contactor, temperature sensors 15 in the electronics 10, 11, the coil 4 and a digital input 16 for messages from other switching devices.
Über das Bussystem 12 können von einer Leitstelle Zustandsab- fragen hinsichtlich Restlebensdauer, Temperatur der Elektronik und der Spule, Steuerspannung und Schaltstellung erfolgen. Außerdem kann von der Leitstelle das Schütz parametriert werden, z. B. können Totzeitkonstanten des Regelkreises der Schützansteuerelektronik und Schwellwerte geändert werden.A control center can use the bus system 12 to inquire about the remaining service life, the temperature of the electronics and the coil, the control voltage and the switching position. The contactor can also be parameterized by the control center, e.g. B. dead time constants of the control circuit of the contactor control electronics and threshold values can be changed.
Dieser modulare und kompakte Aufbau des Spulenkörpers 3 vereinigt die Vorteile des geregelten Schützantriebes mit dem des kompakten Aufbaus, der EMV-Sicherheit und der Bedienungsfreundlichkeit . Auch für anders gestaltete Magnetsysteme z.B. E-Kerne läßt sich ein dementsprechend gestalteter Spulenkörper, in diesem Fall dann mit 3 Durchstecköffnungen einsetzen. This modular and compact design of the coil body 3 combines the advantages of the controlled contactor drive with those of the compact design, EMC safety and ease of use. A correspondingly designed coil body can also be used for differently designed magnet systems, for example E cores, in this case with 3 through openings.
