Aus Keinath, „Die Technik elektrischer Messgeräte", Erster Band Messgeräte und Zubehör, Seite 509 f, Oldenbourg, München und Berlin 1928, ist ein Kabel-Stromwandler zur Messung der Stromverteilung in Mehrfachleitungen bekannt. Der Stromwandler besteht im wesentlichen aus einem Eisenkern mit einem aufklappbaren Schenkel zur unterbrechungsfreien Anschaltung an eine stromführende Leitung und einer Wicklung mit mindestens zwei Anschlüssen zur Anschaltung eines Messinstruments.Out Keinath, "The Technology of Electrical Measuring Instruments ", Volume 1 Measuring Instruments and Accessories, page 509 f, Oldenbourg, Munich and Berlin 1928, is a cable current transformer for measuring the current distribution in multiple lines known. Of the Current transformer essentially consists of an iron core with a hinged leg for uninterrupted connection to a current carrying Cable and a winding with at least two connections to Connection of a measuring instrument.
Der Erfindung liegt daher die Aufgabe zugrunde, eine möglichst einfache Einrichtung zur individuellen potentialfreien Energieversorgung von Feldgeräten anzugeben, die in explosionsgefährdeten Anlagen einsetzbar ist.Of the Invention is therefore based on the object as possible simple device for individual potential-free energy supply of field devices to be specified in potentially explosive atmospheres Equipment is used.
Erfindungsgemäß wird diese Aufgabe mit den Mitteln des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den rückbezogenen Ansprüchen angegeben.According to the invention this Problem solved by the means of claim 1. advantageous Embodiments of the invention are given in the dependent claims.
Die Erfindung geht von einer für sich bekannten Anordnung bestehend aus einem Modulträger mit mindestens einem Steckplatz und mindestens einer steckbaren Baugruppe aus, die auf dem Steckplatz mechanisch gehalten und elektrisch kontaktiert ist.The Invention goes from one for known arrangement consisting of a module carrier with at least a slot and at least one plug-in module, the mechanically held in the slot and contacted electrically is.
Erfindungsgemäß ist der Steckplatz des Modulträgers mit einer Stromwandleranordnung mit einer Primärwicklung und mindestens einer Sekundärwicklung ausgestattet, wobei der Magnetkern der Stromwandleranordnung auf den Modulträger und die steckbare Baugruppe aufgeteilt ist. Die Primärwicklung der Stromwandleranordnung ist Bestandteil des Modulträgers und an eine Wechselspannungsquelle angeschlossen. Die mindestens eine Sekundärwicklung ist Bestandteil der steckbaren Baugruppe.According to the invention Slot of the module carrier with a current transformer arrangement having a primary winding and at least one secondary winding equipped, wherein the magnetic core of the current transformer arrangement the module carrier and the pluggable assembly is split. The primary winding the current transformer assembly is part of the module carrier and connected to an AC voltage source. The at least one secondary winding is part of the plug-in module.
Die steckbare Baugruppe umfasst eine elektrische Schaltung zur Adaption eines Feldgerätestromkreises an die Stromkreise zentraler Einrichtungen.The Plug-in module includes an electrical circuit for adaptation a field device circuit to the circuits of central facilities.
Auf diese Weise wird nach dem für sich bekannten Transformatorprinzip elektrische Energie von dem aus der Wechselspannungsquelle gespeisten Primärstromkreis in den vom Feldgerät belasteten Sekundärstromkreis übertragen. Dabei ist der Sekundärstromkreis galvanisch vom Primärstromkreis getrennt.On this way will be after for known transformer electrical energy from the fed from the AC voltage source primary circuit loaded in the field device Transfer secondary circuit. Here is the secondary circuit galvanic from the primary circuit separated.
Die induktive Energieauskopplung geschieht sowohl beim Hinzufügen als auch beim Entfernen eines Feldgeräts ohne dediziertes Abschalten desselben funkenfrei. Damit ist eine fundamentale Forderung für die Zulassung der erfindungsgemäßen Einrichtung in explosionsgefährdeten Anlagen erfüllt.The Inductive energy extraction happens both when adding as even when removing a field device without dedicated shutdown same spark free. This is a fundamental requirement for approval the device according to the invention in potentially explosive atmospheres Plants met.
