Description
Bremselektromagnet für Amperestundenzähler. Bei den bisher bekannten, vom Verbrauchsstrom durchflossenen und mit magnetischer Sättigung arbeitenden Bremselektromagneten für Amperestundenzähler zur Verbesserung der Fehlerkurve erstreckte sich die magnetische Sättigung auch auf den von der erregenden Wicklung umschlossenen Eisenkern des Elektromagneten. Infolge des hierdurch verursachten hohen Widerstandes im magnetischen Kreise war eine außerordentlich hohe Amperewindungszahl erforderlich, welche zu ganz erheblichen, praktisch kaum anwendbaren Dimensionen der Spulen führten. Vorliegende Erfindung soll diesen Mangel beseitigen.Brake solenoid for ampere-hour meter. With the previously known Brake electromagnets through which the consumption current flows and which work with magnetic saturation for ampere-hour meters to improve the error curve extended the magnetic Saturation also on the iron core of the electromagnet, which is enclosed by the exciting winding. As a result of the resulting high resistance in the magnetic circuit was an extraordinarily high number of ampere-turns required, which leads to considerable, practically hardly applicable dimensions of the coils resulted. Present invention should eliminate this deficiency.
Zu diesem Zweck ist gemäß der Fig. i der Zeichnung der Querschnitt des eigentlichen Eisenkerns i des Bremselektromagneten zwecks schnellerer Erreichung einer kräftigen magnetischen Induktion so groß gehalten, daß eine magnetische Sättigung hier nicht eintritt. Der Querschnitt der Pole 2 und 3 des Elektromagneten hingegen ist so klein bemessen, daß die in dem Kern i bei kleiner Belastung des Zählers und somit geringen Erregung des Elektromagneten erzeugten magnetischen Kraftlinien in den verjüngten Polen 2 und 3 eine große Dichte erreichen, derartig, daß hier alsbald eine magnetische Sättigung eintritt.For this purpose, according to FIG. 1 of the drawing, the cross section the actual iron core i of the brake electromagnet for the purpose of faster achievement a strong magnetic induction kept so great that a magnetic saturation does not enter here. The cross-section of poles 2 and 3 of the electromagnet, however is dimensioned so small that the in the core i with a small load of the counter and thus low excitation of the electromagnet generated magnetic lines of force in the tapered poles 2 and 3 reach a great density, such that here soon magnetic saturation occurs.
Zur Verstärkung der Bremsung ist es ferner vorteilhaft, daß die Einwirkung der Bremselektromagneten nicht nur auf die Bremsscheibe allein, sondern gleichzeitig auf die Ankerwicklung erfolgt in dem- Sinne, daß dem Anker q. hierdurch ein seiner Drehung entgegenwirkendes Drehmoment erteilt wird. Aus diesem Grunde sollen Pole des Bremselektromagneten außerhalb der neutralen Zone des Ankers q. angeordnet sein.To increase the braking, it is also advantageous that the action the brake solenoid not only acts on the brake disc alone, but at the same time on the armature winding takes place in the sense that the armature q. thereby one of his Rotation counteracting torque is given. For this reason, Poles should of the brake electromagnet outside the neutral zone of the armature q. be arranged.
Zur Verminderung des Eigenverbrauchs des Zählers kann die Wicklnng 5 des Elektromagneten gleichzeitig ganz oder teilweise den Nebenschluß 6 des Zählers bilden.To reduce the meter's own consumption, the winding 5 of the electromagnet at the same time wholly or partially the shunt 6 of the counter form.
