Der Erfindiingsgegenstand ist ein asiatischer Elektrizitätszähler, welcher infolge einer besonderen Anordnung der Hauptstromwicklung die Verwendung eines Ankers von geringster magnetischer Außenwirkung und demzufolge geringster Abhängigkeit von äußeren magnetischen Feldern ermöglicht, so daß eine Beeinträchtigung der Zählerangaben durch äußere, dem Zähler absichtlich oderThe Erfindiingsgegenstand is an Asian electricity meter, which due to a special arrangement of the main current winding, the use of which enables an armature of least magnetic visibility and consequently lowest function of external magnetic fields, so that a deterioration of the counter information intentionally or by external, the counter

ίο unabsichtlich genäherte Magnetfelder, sowie durch das Erdfeld verhütet wird.ίο unintentionally approached magnetic fields, as well is prevented by the earth's field.

Ferner wird durch die vorliegende Anordnung der Hauptstromwicklung erreicht, daß die Schenkel des Ankers von den FeIdspulen vollkommen eingeschlossen werden und während ihrer ganzen Bewegung unter dem Einfluß der Hauptstromwicklung verbleiben, wodurch eine günstige Ausnutzung der magnetischen Kräfte stattfindet.Furthermore, the present arrangement of the main current winding achieves that the legs of the armature are completely enclosed by the field coils and remain under the influence of the main current winding throughout their movement, whereby a favorable utilization of the magnetic forces takes place.

Der Apparat gehört zu der Gruppe von Zählern, bei welcher die Nebenschlußwicklung des Ankers feststehend angeordnet ist und einen mit der Achse drehbaren Körper (Anker) geeigneter Form aus parämagnetischem Material magnetisiert. Derartige Anordnungen des Ankers sind durch die Patente 103008 (Anspruch 2) und 129686 bekannt geworden, jedoch sind bei diesen Einrichtungen die Anker nicht astatisch und infolgedessen von äußeren Magnetfeldern in hohem Maße abhängig.The apparatus belongs to the group of meters in which the shunt winding of the armature is arranged stationary and a body (armature) rotatable with the axis of suitable shape made of paremagnetic Material magnetized. Such arrangements of the armature are known from patents 103008 (claim 2) and 129686 become, however, the anchors in these facilities are not astatic and consequently highly dependent on external magnetic fields.

Eine astatische Anordnung der Schenkel des Ankers ist durch das britische Patent 23334/1898 (Fig. 15 bis 18) bekannt geworden.An astatic arrangement of the legs of the anchor is by the British patent 23334/1898 (Fig. 15 to 18) became known.

Bei dieser Einrichtung haben die Hauptstromspulen und die Nebenschlußspule gleiche Achsrichtung, wie in Fig. 1 und 2 der beiliegenden Zeichnung vergleichsweise dargestellt ist. Es ist nun klar, daß die Schenkel des Ankers 1 in der durch Fig. 1 veranschaulichten Stellung von den beiden Spulen 5 und ζ^α nur in geringem Maße oder gar nicht beeinflußt werden, da die Kraftlinien des Ankers, die von einem zum anderen Schenkel verlaufen, in dieser Stellung keine Windüngen der Hauptstromwicklung passieren, so daß höchstens nur noch das Streufeld der Spulen 5 und 5ⁿ zur Wirkung kommen kann. Hierbei befindet sich also der Anker 1 gerade in der Stellung, in welcher er bei günstiger Spulenanordnung sein größtes Drehmoment haben sollte, nicht im Bereich der ablenkenden Wicklungen.In this device, the main current coils and the shunt coil have the same axial direction, as shown for comparison in FIGS. 1 and 2 of the accompanying drawings. It is now clear that the legs of the armature 1 in the position illustrated by FIG. 1 are influenced only to a small extent or not at all by the two coils 5 and ζ ^α , since the lines of force of the armature, which run from one leg to the other , in this position no turns of the main current winding happen, so that at most only the stray field of the coils 5 and 5 ⁿ can come into effect. In this case, the armature 1 is precisely in the position in which it should have its greatest torque with a favorable coil arrangement, not in the area of the deflecting windings.

Bei vorliegender Spulenanordnung, welche durch Fig. 3 bis 6 in mehreren Ausführungsformen schematisch veranschaulicht wird, ist dieser Mangel dadurch beseitigt, daß die Achsen der Feldspulen, wie bei einem Galvanometer, rechtwinklig zur Zählerachse stehen, so daß sie die günstigste Wirkung auf die Schenkel des Ankers ausüben können, d. h. das ganze Feld der Spulen wird ausgenutzt. Jedoch muß hier, Und hierin liegt das Wesen der Erfindung, die Anordnung der Spulen derartig getroffen sein, daß sich entweder jeder Schenkel des Ankers in einem besonderen Hauptstromspulenfelde dreht, oder es ist nur ein Hauptfeld vorhanden, in welchem sich jedoch nur ein Schenkel bewegen darf, da ein gemeinsames Feld für beide Schenkel infolge der astatischen Anordnung der Sehenkel ohne Wirkung bliebe.In the present coil arrangement, which is illustrated by FIGS. 3 to 6 in several embodiments is illustrated schematically, this deficiency is eliminated by the fact that the axes of the field coils, as in a galvanometer, are at right angles to the meter axis so that they can have the most beneficial effect on the armature legs, d. H. the whole field of the coils is used. However, here must be, and here lies the essence of the invention, the arrangement of the coils be made such that either each leg of the armature rotates in a special main current coil field, or there is only one main field in which, however, only one leg move may, as a common field for both legs due to the astatic arrangement the sinew would have no effect.

Claims

3 and 4 show an embodiment of the counter with a double coil arrangement. Although the distance of the coil 5 from 5 ^ and 6 from 6a is due to the size of the coil 4 and is quite considerable, this group still has a more favorable effect than the coil arrangement according to FIGS. 1 and 2, because with it the main field is rectangular the plane of movement of the legs passes through the axis 2, so that the legs ia and 1 * always remain in the field. However, the arrangement according to FIG. 5 is more favorable, in which the shunt coil 4 and the leg \ a are enclosed by the main current coils 5 and 5a, while the leg 1 * circles outside the main current coils 5 and 5 ". In this device, the main current coils move very close together, and since the main stream winding located between the legs ia and ib. can be of small thickness, it is possible to bring the two legs so far together by cranking one or both of them so that there is just enough space for the windings of the coils 5 and 5a and possibly the auxiliary starting coil (not shown in the drawing), whereby the lowest external magnetic effect, i.e. the best astatic effect, is obtained body 1 and 1 'consisting of magnetic material are attached, one or both of which are magnetized by windings 4 and Aa, respectively. The arms ia and ib located at the mutually facing ends of 1 and i1 offer, like the aforementioned embodiments, the same possibility of being influenced by one or two groups of coils of the main current.
