Abstract

The field around the electrical conductor (10), in a push-through opening (2), is converted into a current measurement value using transducers (3), an amplifier stage (5) and a microcontroller (7). The controller provides the measurement value along with control commands,based on variable software parameters, to the bus system.

Description

Die Erfindung betrifft eine Strommesseinrichtung für die Gebäudesystemtechnik der im Oberbegriff des Patentan­ spruchs 1 angegebenen Art. Die ermittelten Messwerte wer­ den, sowie die daraus resultierenden Steuerbefehle, direkt über das Bussystem der Gebäudesystemtechnik übertragen.The invention relates to a current measuring device for the Building system technology in the preamble of Patentan pronounced 1 specified type. The determined measured values who the, as well as the resulting control commands, directly transmitted via the building system technology bus system.

Strommesswandler zur Erfassung des Stromflusses in elek­ trischen Leitern sind geläufig. Sie dienen zur galvanisch getrennten rückwirkungsfreien Messung von Gleich-, Wechsel- und Impulsströmen in elektrischen Anlagen.Current transducers for measuring the current flow in elec tric ladders are common. They are used for galvanic separate non-reactive measurement of direct, AC and pulse currents in electrical systems.

Der Erfindung liegt die Aufgabe zugrunde, eine Strommess­ einrichtung der im Oberbegriff des Patentanspruchs 1 ange­ gebenen Art zu schaffen. Die Lösung dieser Aufgabe erfolgt mit den im kennzeichnenden Teil des Anspruchs 1 angegebe­ nen Merkmalen.The invention has for its object a current measurement establishment of the in the preamble of claim 1 given way of creating. This task is solved with the specified in the characterizing part of claim 1 characteristics.

Die Erfindung soll nun anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher er­ läutert werden:
Das Gehäuse 1 des Elektroinstallationsgerätes, welches vorzugsweise als Reiheneinbaugerät für die Montage auf einer Hutprofilschiene nach DIN EN 50022 ausgeführt ist, weist Durchstecköffnungen 2 auf. Durch diese Durchsteck­ öffnungen wird der stromdurchflossene elektrische Leiter 10 geführt. Im Inneren des Elektroinstallationsgerätes ist ein Messwandler 3 so angebracht, dass er die Durchsteck­ öffnung 2 umschließt. Das den elektrischen Leiter 10 umgebende Magnetfeld induziert im Messwandler einen magnetischen Fluss, welcher durch eine Sekundärbeschaltung 4 abgegriffen und der Verstärkerschaltung 5 zugeführt wird. Das in der Verstärkerstufe 5 aufbereitete Signal 6, welches proportional dem Strom im elektrischen Leiter ist, wird dem Mikrokontroller 7 zugeführt. Im Mikrokontroller wird dieses Messsignal ausgewertet. Über eine Busankopp­ lung 8 mit Anschlussstelle 9 meldet der Mikrokontroller 7 den Messwert auf das nachgeschaltete Bussystem der Gebäu­ desystemtechnik. Des weiteren hat der Mikrokontroller die Möglichkeit Steuerbefehle auf das Bussystem auszugeben in Abhängigkeit von einstellbaren Softwareparametern wie z. B. Schwellwertüber- oder -unterschreitungen.The invention will now be explained in more detail using an exemplary embodiment shown roughly schematically in the drawing:
The housing 1 of the electrical installation device, which is preferably designed as a modular installation device for mounting on a top-hat rail according to DIN EN 50022, has through openings 2 . The current-carrying electrical conductor 10 is guided through these push-through openings. In the interior of the electrical installation device, a measuring transducer 3 is attached in such a way that it encloses the push-through opening 2 . The magnetic field surrounding the electrical conductor 10 induces a magnetic flux in the transducer, which is tapped by a secondary circuit 4 and fed to the amplifier circuit 5 . The signal 6 processed in the amplifier stage 5 , which is proportional to the current in the electrical conductor, is supplied to the microcontroller 7 . This measurement signal is evaluated in the microcontroller. Via a bus coupling 8 with connection point 9, the microcontroller 7 reports the measured value to the downstream bus system of the building system technology. Furthermore, the microcontroller has the option of issuing control commands to the bus system as a function of adjustable software parameters such as. B. Threshold violations.
