Description
Anordnung zur Erfassung der elektrischen Energie mehrerer Verbraucher mittels elektronischer Meßgeräte, insbes. elektronischer Elektrizitätszähler Arrangement for recording the electrical energy of several consumers by means of electronic measuring devices, especially electronic electricity meters
Die Erfindung bezieht sich auf eine Anordnung zur Erfassung der elektrischen Energie mehrerer Verbraucher mittels elektronischer Meßgeräte, insbesondere elektronischer Elektrizitätszähler, welche aus mehreren Funktionseinheiten zusammengesetzt sind.The invention relates to an arrangement for detection the electrical energy of several consumers by means of electronic measuring devices, in particular electronic electricity meters, which are composed of several functional units.
Die Abrechnung der im Haushalt verbrauchten elektrischen Energie durch elektronische Elektrizitätszähler ist z.Z. nicht wirtschaftlich, wenn daran gedacht ist, den Elektrizitätszähler, der bisher nach dem Ferrarisprinzip arbeitet, durch ein entsprechendes elektronisches Meßwerk zu ersetzen.The billing of the electrical energy consumed in the household by electronic electricity meters is currently not economical if you think about using the electricity meter, which has so far worked according to the Ferrari principle, to be replaced by an appropriate electronic measuring mechanism.
Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit aufzuzeigen, wie der Einsatz elektronischer Elektrizitätszähler wirtschaftlicher gemacht werden kann. Erfahrungsgemäß setzt sich ein elektronischer Elektrizitätszähler aus mehreren Funktionsgruppen zusammen, wie beispielsweise Stromvereorgungsteil, Multiplikator, Integrator, Umwerter und Zählwerk. Das der Erfindung zugrunde liegende Problem kann gemäß der Erfindung dadurch gelöst werden, daß die elektronischen Elektrizitätszähler mehrerer Verbraucher zu.Gruppen zusammengefaßt sind und daß innerhalb jeder Gruppe mehrere gleichwirkende Funktionseinheiten der elektronischen kWh-Zähler durch eine entsprechende einzige Funktionseinheit ersetzt sind. Beispielsweise bedingt der für elektronische Meßeinrichtungen stets erforderliche Netzteil zur Versorgung der einzelnen Baugruppen, bezogen auf das Gesamtgerät, einen relativ hohen Grundaufwand. Dadurch, daß nun für mehrere elektronische Elektrizitätszähler die Stromversorgung nurThe invention is based on the object of showing a possibility, such as the use of electronic electricity meters can be made more economical. Experience has shown that an electronic electricity meter is made up of several Functional groups together, such as power supply, Multiplier, integrator, corrector and counter. The problem on which the invention is based can, according to the invention be solved in that the electronic electricity meters of several consumers zu.Gruppen combined are and that within each group several functionally equivalent units of the electronic kWh meter are replaced by a corresponding single functional unit. For example, the condition for electronic measuring devices always required power supply unit for supplying the individual assemblies, based on the overall device relatively high basic effort. Because now the power supply for several electronic electricity meters only

einmal vorgesehen zu sein braucht, wird eine wesentliche Herabsetzung des Aufwandes erzielt. Vorzugsweise ist jede Funktionseinheit als Einschub eines Einschubsystems ausgebildet. Dies ist insbesondere für größere Anlagen, wie beispielsweise Mehrfamilienhaus ei; Hochhäuser sehr sinnvoll. Bei speziellen Multiplizierverfahren besteht weiterhin die Möglichkeit, außer der Stromversorgung auch andere Funktionseinheiten zusammenzufassen. once needs to be provided, a significant reduction in the effort is achieved. Preferably each is Functional unit designed as a slide-in system of a slide-in system. This is especially true for larger systems, such as Apartment building egg; High-rise buildings make a lot of sense. In the case of special multiplication methods, it is still possible to combine other functional units in addition to the power supply.
Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, wird die Erfindung näher erläut-ert. Sie zeigt ein Einschubsystem zur Erfassung der elektrischen Energie mehrerer Verbraucher mit Hilfe von elektronischen Meßgeräten. Beispielsweise sollen η-Verbraucher vorgesehen sein, wobei mit V1, V2...Vn die einzelnen kWh-Meßeinschübe der Verbraucher bezeichnet sind. Diese Meßeinheiten sind aus elektronischen Bauteilen aufgebaut, die durch einen gemeinsamen Stromversorgungsteil N mit Spannung versorgt werden. Die einzelnen Meßeinschübe stehen mit diesem Netzteil über die Leitungen +Ug, Erde und -u-g in Verbindung, wie bei dem Meßeinschub V1 angedeutet ist. Die Meßeinschübe enthalten in üblicher Weise die Multiplikatoren M1, M2 und M3 für die einzelnen Phasen R, S und T sowie einen Integrator I, einen Schrittmotor M und ein Zählwerk Z. Schon allein der Ersatz des Netzteiles N für sämtliche Meßeinschübe V1 bis Vn ergibt eine wesentliche Herabsetzung des Gesamtaufwandes.Based on the drawing, in which an exemplary embodiment is shown is, the invention is explained in more detail. she shows a slide-in system for recording the electrical energy of several consumers with the help of electronic measuring devices. For example, η consumers should be provided, with V1, V2 ... Vn indicating the individual kWh measuring units of the consumers are designated. These measuring units are made up of electronic components that are fed by a common power supply N are supplied with voltage. The individual measuring units are connected to this power supply unit via the cables + Ug, earth and -u-g in connection, as with the measuring insert V1 is indicated. The measuring units usually contain the multipliers M1, M2 and M3 for the individual phases R, S and T as well as an integrator I, a stepping motor M and a counter Z. Just the replacement of the power supply unit N alone for all measuring inserts V1 to Vn results in a significant reduction in the total effort.
Eine weitere Herabsetzung des Aufwandes kann beispielsweise durch die Wahl eines speziellen Multiplizierverfahrens ermöglicht werden. Wird beispielsweise zur Ermittlung der elektrischen Leistung das sog. Time-Division-Verfahren verwendet, dann kann zu dem ein Multiplikant, - in diesem Falle die Netzspannung U - zentral erfaßt werden und nach Umwandlung in eine Impulsdauermodulation den einzelnen kWh-Einschüben parallel zugeführt werden. Bei dem in der Figur dargestellten Ausführungsbeispiel sind den kWh-Meßeinschüben V1 bis Vn die Modulatoren MR, MS, MT für die Phasenspannungen UR, Ug und UT zugeordnet. Über die Schienen 1,A further reduction in effort can be made possible, for example, by choosing a special multiplication method. If, for example, the so-called time division method is used to determine the electrical power, then a multiplicant - in this case the mains voltage U - can be recorded centrally and, after conversion into a pulse duration modulation, fed in parallel to the individual kWh slots. In the embodiment shown in the figure, the kWh measuring units V1 to Vn are assigned the modulators MR, MS, MT for the phase voltages U R , Ug and U T. Via the rails 1,

und 3 werden die Ausgangssignale der Modulatoren den Ansteuesstufen A1, A2 und A3 der einzelnen Meßwerke M1, M2 und M3 zugeführt. Der Vorteil ist auch hierbei, daß für mehrere Zähler nur ein Satz Spannungswandler sowie ein Satz Spannungs-Impulsdauer-Wandler benötigt werden. Die andere Meßgröße, und zwar die Ströme IR, Ig und I„,, werden in üblicher Weise über Stromwandler den Meßwerken MT bis M3 zugeführt.and 3, the output signals of the modulators are fed to the control stages A1, A2 and A3 of the individual measuring units M1, M2 and M3. The advantage here is that only one set of voltage converters and one set of voltage / pulse duration converters are required for several counters. The other measured variable, namely the currents I R , Ig and I "", are fed to the measuring units MT to M3 in the usual way via current transformers.
