Description

Gegen Spannungsschwankungen unempfindliches elektrisches Wechselstrominstrument zum messen, Summieren und Registrieren. Die Erfindung betrifft ein elektrisches Meßinstrutnent, mit Hilfe dessen Vorgänge gemessen, summiert und registriert werden, die durch Änderungen von Stromstärken angezeigt werden.Electric alternating current instrument insensitive to voltage fluctuations for measuring, totalizing and registering. The invention relates to an electrical one Measuring instrument with the help of which processes are measured, totaled and registered, indicated by changes in current levels.

Die bekannten Strommesser haben den großen Nachteil, daß wegen ihrer unpr oportionalen Skala insbesondere im unteren ?NTeßbereich große Meßungenauigkeiten auftreten. Aus diesem Grunde können nur Instrumente mit Wattmeter schaltung Verwendung finden, wie Zähler, Wattmeter u. dgl. Diese Instruinente haben aber, ihrer Aufgabe entsprechend, die Eigenschaft, auf die Schwankungen, die vielfach in den Leitungsnetzen vorkommen, sofort anzusprechen. Infolgedessen. sind sie für die vorliegende Aufgabe unbrauchbar, da es nicht möglich ist, mit einem solchen Instrument unter Anschluß an ein vorhandenes Leitungsnetz laufend richtig zu messen.The known ammeters have the major disadvantage that because of their unproportional scale, especially in the lower measuring range, large measurement inaccuracies appear. For this reason, only instruments with a wattmeter circuit can be used find, such as counters, wattmeters, etc. However, these instructors have their job accordingly, the property on the fluctuations that often occur in the line networks occur to address immediately. Consequently. are they for the task at hand unusable because it is not possible to use such an instrument under connection continuously and correctly measure on an existing pipeline network.

Die Erfindung löst die Aufgabe durch Verwendung eines an sich bekannten Wattmeters oder Zählers, der wie folgt gebaut ist: Der übliche Bremsmagnet kommt in Wegfall. Die Spannungsspule wird so dimensioniert, claß das Spannungseisen immer vollständig magnetisch gesättigt ist und außerdem durch Weglassung des sonst bei Wechselstromzählern üblichen magnetischen Nebenschlusses immer voll zur Wirkung kommt. Außerdem wird das Verhältnis zwischen den Strom- und Spannungsspulen so gewählt, daß auch die veränderliche Spannung in der Stromspule keinen Einfluß auf das Meßergebnis hat. Das Instrument gestattet in an sich bekannter Weise, genau wie ein Stromzähler, den jeweiligen Verbrauch anzugeben oder auch den Verbrauch zu summieren bzw. zu registrieren.The invention solves the problem by using a known one Wattmeter or counter, which is built as follows: The usual brake magnet comes in omission. The tension coil is dimensioned in such a way that the tension iron always remains is completely magnetically saturated and also by omitting the otherwise with AC meters with the usual magnetic shunt always have full effect comes. In addition, the ratio between the current and voltage coils is chosen so that that even the variable voltage in the current coil has no influence on the measurement result Has. In a manner known per se, the instrument, just like an electricity meter, allows to indicate the respective consumption or to total or add the consumption to register.
