Zufällig auftretende Fehler an Drehstromzählern, z. B. das Durchschlagen einer Nebenschlußspule infolge atmosphärischer Entladungen, sind schwer aufzufinden, weil diese Zähler hierbei weiterlaufen und bei einer gewissen Phasenverschiebung unter Umständen den Verbrauch sogar noch ziemlich richtig anzeigen. Kommen dazwischen aber Perioden starker Belastung vor, so werden die Fehler in denRandom errors in three-phase meters, e.g. B. the breakdown of a shunt coil as a result of atmospheric discharges, are difficult to find because these meters in this case continue to run and with a certain phase shift possibly the consumption show pretty correctly even. If, however, there are periods of heavy load in between, the errors are in the
ίο Angaben sehr groß, ohne daß es ein Mittel gibt, dieselben rechtzeitig zu erkennen.ίο information very large without there being any means there to recognize them in time.
Nach der vorliegenden Erfindung werden Fehler dieser Art akustisch angezeigt durch eine Membran o. dgl., die unter dem Einfluß mehrerer in den verschiedenen Spannungskreisen liegender Elektromagnete steht. Die Spulen dieser Magnete können auf verschiedene Kerne oder übereinander auf einen einzigen Kern gewickelt sein. Die Spulen sind so angeordnet, daß sich die mechanischen bzw. elektrischen Kräfte bei normalem Lauf des Zählers das Gleichgewicht halten, während bei Unterbrechung in einem der Kreise die Membran zum Anschlagen gegen einen "festen Gegenstand und so zum Summen gebracht wird. Die Fig. ι und 2 zeigen Ausführungsbeispiele der. Erfindung für ein Dreileiter- und für ein Vierleiterdrehstromsystem.According to the present invention, errors of this type are indicated acoustically by a membrane or the like, which is under the influence of several electromagnets lying in the various voltage circuits. the Coils of these magnets can be on different cores or on top of each other on a single one Be wound core. The coils are arranged so that the mechanical resp. electrical forces keep the equilibrium during normal running of the meter, while at Break in one of the circles the membrane to strike against a "solid object and so made to hum. FIGS. 1 and 2 show exemplary embodiments the. Invention for a three-wire and for a four-wire three-phase system.
In Fig. ι bedeuten a, b, c die drei Leiter des Verbrauchsstromes, d und e die Nebenschlüsse für die Spannungsspulen zwischen jeIn Fig. Ι a, b, c mean the three conductors of the consumption current, d and e the shunts for the voltage coils between each
,- einem Leiter α und b einerseits und dem Leiter c andererseits, f und g sind zwei Magnete, die von je einem der Nebenschlußströme durchfloßen werden und zu beiden Seiten der Membran h liegen. Die Kräfte der beiden Elektromagnete f und g halten sich bei normalem Betrieb das Gleichgewicht, so daß die Membran zwischen ihnen frei und lautlos schwingt; wird einer der Nebenschlüsse unterbrachen, so zieht der Magnet des anderen Nebenschlusses allein die Membran an, dieselbe schlägt an ihn oder einen beliebigen festen Gegenstand an und schnarrt.- a conductor α and b on the one hand and the conductor c on the other hand, f and g are two magnets, each of which has one of the shunt currents flowing through them and which lie on both sides of the membrane h. The forces of the two electromagnets f and g are in equilibrium during normal operation, so that the membrane swings freely and silently between them; If one of the shunts is interrupted, the magnet of the other shunt attracts the membrane alone, which strikes it or any solid object and purrs.
In Fig. 2 ist ein Drehstromvierleitersystem mit den Leitern a, b, c, d dargestellt, e, f, g sind die Nebenschlüsse zwischen den Leitern a, b, c und dem Nulleiter d. Die Spulen der Elektromagnete für die Nebenschlüsse sind hier um einen einzigen Kern i gewickelt, vor dem die Membran h liegt. Bei normalem Betrieb üben die drei Wicklungen keine Wirkung auf den Eisenkern aus; wird aber einer der Nebenschlüsse unterbrochen, so beginnt die Membran zu schnarren.In Fig. 2 a three-phase four-conductor system with the conductors a, b, c, d is shown, e, f, g are the shunts between the conductors a, b, c and the neutral conductor d. The coils of the electromagnets for the shunts are here wound around a single core i , in front of which the membrane h is located. In normal operation, the three windings have no effect on the iron core; but if one of the shunts is interrupted, the membrane begins to purr.
In beiden Fällen hält das Schnarren oder Summen so lange an, bis der Fehler abgestellt ist.In both cases, the buzzing or humming continues until the error is eliminated is.
