Description

Einrichtung -zur Messung der Scheinleistung bzw. des Scheinverbrauchs in Wechselstromkreisen Es ist bekannt, daß in der Elektrotechwk ein großes Bedürfnis nach: einer Meßvorrichtung besteht, welche es mit einfachen Mitteln. gestattet, die Scheinleistung bzw. den Sdlieinverb'rauch in Wechselstromanlagen zu messen. Trotz der verschiedensten Vorschlage ist in dieser Hinsicht eine befriedigende Lösung bis'h'er nicht gefunden worden.Device - for measuring the apparent power or the apparent consumption in AC circuits It is known that there is a great need in the electrical engineering industry after: a measuring device consists, which it with simple means. allowed to measure the apparent power or the southern consumption in AC systems. Despite the most diverse proposals, there is a satisfactory solution in this regard until'h'er was not found.

Durch, die vorliegende Erfindung wird eine neue Einrichtung angegeben, welche geeignet ist, diese Aufgabe in befriedigender Weise zu läsen. Erfindungsgemäß wird: die Messung der Scheinleistung b@zw. des Scheinverbrauches dadurch durchgeführt, daß zwei umlaufende Meßsysteme nach Art eines Elektriztätgzählexantrieb@es vorgesehen werden., von denen jedes .einen Gleichstromerzeuger antreibt. Hierbei sollen die Meßsysteme in an sich bekannter Weise so eingerichtet sein, daß die Drehzahl. des, einen von beiden: nur von der Spannung, die Drehzahl des anderen nur vorn dem Strom' des Wechselstromkreises abhängig ist. Die von beiden Meßsystemen angetriebenen Stromerzeuger sind an je eine Meßspule eines Wattmeters bzw. Wattstundenzählers, angeschlossen, so daß, da die gelieferte Gleichspannung durch die Drehzahl des Gleichstromerzeugers bestimmt ist, diese Instrumente die Scheinleistung bzw. den Scheinverbrauch unmittelbar anzeigen. In der Abbildung ist eine Einrichtung dieser Art schematisch dargestellt. a sind die umlaufenden Meßsysteme nach Art eines Elekhizitätszäblerantrebes, von. denen das eine von der Spannung, das andere vom Strom des betreffenden Wechselstromkreises beeinfiußt wird. jedes Meßinstrument treibt einen Gleichstromerzeuger an, welcher aus der Ankerscheibe .d', aus dem Feldmagneten i und aus, dem Kollektor e besteht. Jeder Gleichstromerzeuger ist an eine Meßspule eines Mattmeters oder Wattstundenzäblers t angeschlossen, so daß dieses Instrument die Scheinleistung bzw. den Scheinverbrauch des Wechselstromkreises unmittelbar anzeigt.The present invention provides a new device which is capable of satisfactorily accomplishing this object. According to the invention: the measurement of the apparent power b @ zw. of the bill consumption carried out in that two revolving measuring systems in the manner of an Elektriztätgzählexantrieb @ it are provided, each of which drives a DC generator. Here, the measuring systems should be set up in a manner known per se so that the speed. one of the two: depends only on the voltage, the speed of the other depends only on the current of the alternating current circuit. The generators driven by both measuring systems are each connected to a measuring coil of a wattmeter or watt-hour meter, so that, since the DC voltage supplied is determined by the speed of the DC generator, these instruments display the apparent power or consumption directly. A device of this type is shown schematically in the figure. a are the rotating measuring systems in the manner of an Elekhizitätszäblerantrebes, of. one of which is influenced by the voltage and the other by the current of the respective AC circuit. Each measuring instrument drives a direct current generator, which consists of the armature disk .d ', of the field magnet i and of, the collector e. Each DC generator is connected to a measuring coil of a matt meter or watt hour meter t, so that this instrument shows the apparent power or the apparent consumption of the alternating current circuit directly.
