 strichelt sind in der Zeichnung noch zwei Winkel c angedeutet, die neben den Winkeln b angebracht werden können, um noch einen magnetischen Nebenchluss zum Pfade des wirksamen Spannung feldes und auch zu dem Teile des   Spannungsfeldea   zu bilden, der durch die Winkel b vom mittleren Schenkel nach den äusseren Schenkeln   des Kernes a fliesst.   



   In Fig. 2 sind bei f, g die Hauptstromspulen angedeutet. e bedeutet den   linsenförmigen   Anker ; er ist aus   länglichen,     feindrähtigen   Spulen aufgeschichtet zu denken und enthält einen scheibenförmigen Kern e'aus Eisen.

   Ein solcher magnetischer Nebenschluss unterscheidet sich, abgesehen von seiner Anordnung auf dem Anker grundsätzlich von dem magnetischen Nebenschluss zum Pfade des wirksamen Hauptstromfeldes, der in* der deutschen Patentschrift Nr.   156000   beschrieben ist. Dieser Neben-   schluss   soll bei einem   dynamojnetrischen Zähler,   bei dem der Pfad des Hauptstromfeldes in der Hauptsache aus Eisen besteht, die-von der Remanenz dieses Eisens herrührenden Fehler bei

   zunimmt.   Der   Nebenschluss   nach dieser Patentschrift muss deshalb ein Sinken des wirksamen Hauptstromfeldes im Verhältnis zur   Hauptstromstarke   bei den höheren Werten des Hauptstromes bewirken, also gerade das Gegenteil von dem,

   was mit dem hier   beschriebenen Nebenschluss be-   zwecktwird. 



   PATENT-ANSPRÜCHE :
1. Elektrizitätszähler mit einem   magnetischen Nebenschluss   zum Pfade des wirksamen Hauptstromfeldes, gekennzeichnet durch eine solche Wahl der Abmessungen und des Stoffes   für diesen Nebenschluss, dass er sich unter dem   Einfluss der das wirksame Hauptstromfeld erzeugenden Hauptstromwicklung sättigt, the der Hauptstrom die der vollen Belastung entsprechendeStärkeerreicht.

 In the drawing, dashed lines indicate two angles c, which can be attached next to angles b in order to form a magnetic shunt to the path of the effective voltage field and also to the part of the voltage field a that is followed by the angle b from the middle leg the outer legs of the core a flows.



   In Fig. 2, the main current coils are indicated at f, g. e means the lenticular anchor; it is to be thought of as stacked up from elongated, fine-stranded coils and contains a disc-shaped core made of iron. The effective main current field here is the field that is generated by the armature winding after the parts of the armature core e 'protruding into the main current coils f, g.
 EMI2.1
 



   Such a magnetic shunt, apart from its arrangement on the armature, differs fundamentally from the magnetic shunt to the path of the effective main current field, which is described in German Patent No. 156000. In the case of a dynamo-netric meter, in which the path of the main current field consists mainly of iron, this shunt is supposed to reduce the errors resulting from the remanence of this iron
 EMI2.2
   increases. The shunt according to this patent must therefore cause a decrease in the effective main current field in relation to the main current strength at the higher values of the main current, i.e. exactly the opposite of that

   what is the purpose of the shunt described here.



   PATENT CLAIMS:
1. Electricity meter with a magnetic shunt to the path of the effective main current field, characterized by such a choice of dimensions and material for this shunt that it saturates under the influence of the main current winding generating the main current field, the main current reaches the strength corresponding to the full load.
