Description

ij verbunden und in bekannter Weise in den Stromkreis der Schaltuhr eingeschaltet zu denken ist. Diese Spannungswicklung ist aber in bezug auf die erfindungsgemäß weiter angeordnete Zusatzwicklung, wie unten beschrieben ist, noch besonders bemessen. Die Zusatzwicklung 18 ist in Reihe mit der Hauptstromwicklung 19 des Zählers zwischen die Hauptstromklemmen 20, 21 eingeschaltet. 22 ist die Spannungswicklung des Zählers, die in bekannter Weise einerseits von der Hauptstromklemme 20 abgezweigt, andererseits zu einer freien Spannungsklemme 23 geführt ist.
Die beiden Wicklungen des Schaltrelais sind nun so abgestimmt, daß bei Erregung der Wicklung 13 der Anker 11 noch nicht angezogen, also eine Umschaltung noch nicht bewirkt ist, daß sie aber eintritt, wenn durch die Wicklung 18 noch ein Strom bestimmter Stärke hindurchfließt. Es wird dann nach Eintritt der Sperrzeit, bei dem die Wicklung 13 eingeschaltet wird, nicht,, wie sonst üblich, sogleich eine Umschaltung erfolgen. Diese wird vielmehr erst dann eintreten, wenn die Belastung des Zählers eine bestimmte Grenze überschreitet. Erfindungsgemäß wird diese Grenze so zu bemessen sein, daß der Stromverbrauch der Lampen unter diese Grenze, des Bügeleisens, Kochers o. dgl. aber über diese Grenze fällt. Der höhere Tarif tritt dann nur für diese Kraftstrom verbrauchenden Apparate in Kraft. ij connected and switched on in a known manner in the circuit of the timer. However, this voltage winding is still specially dimensioned with respect to the additional winding arranged further according to the invention, as is described below. The additional winding 18 is connected in series with the main current winding 19 of the meter between the main current terminals 20, 21. 22 is the voltage winding of the meter which, on the one hand, is branched off in a known manner from the main current terminal 20 and, on the other hand, is led to a free voltage terminal 23.
The two windings of the switching relay are now coordinated so that when the winding 13 is energized, the armature 11 is not yet attracted, that is, switching has not yet been effected, but that it occurs when a current of a certain strength still flows through the winding 18. After the blocking time has entered, in which the winding 13 is switched on, a switchover will not take place immediately, as is otherwise usual. Rather, this will only occur when the load on the meter exceeds a certain limit. According to the invention, this limit is to be dimensioned so that the power consumption of the lamps falls below this limit, that of the iron, stove or the like, but falls above this limit. The higher tariff then only comes into force for these power-consuming devices.

Die Erfindung bietet gegenüber der bekannten Einrichtung für denselben Zweck zunächst den Vorteil größerer Einfachheit, da die beweglichen Teile und Kontakte des Hauptstromrelais der bekannten Einrichtung fortfallen. Ein weiterer Vorteil besteht in der exakteren Arbeitsweise. Durch die Wicklung erfährt nämlich der Kern 12 des Relais eine bestimmte Magnetisierung, über sie lagert sich dann die zusätzliche Magnetisierung durch die Wicklung 18. Der Betrag der Gesamtmagnetisierung bei bestimmter Stromstärke in der Wicklung 18 ist dabei in viel höherem Maße eindeutig durch diese Stromstärke bestimmt, als es bei einem gewöhnlichen Hauptstromrelais wegen der Remanenz des Eisens erfahrungsgemäß der Fall ist.The invention offers compared to the known device for the same purpose first the advantage of greater simplicity, as the moving parts and contacts of the main power relay the known facility. Another advantage is the more precise way of working. Through the winding namely, if the core 12 of the relay experiences a certain magnetization, it is superimposed on it Then the additional magnetization through the winding 18. The amount of the total magnetization at a certain current strength in the winding 18 is much higher Dimensions clearly determined by this amperage than is the case with an ordinary main current relay experience has shown that this is the case because of the remanence of iron.

Double tariff meter. Patented in the German Empire on March 6, 1917.

Small consumers of electrical energy that only have some light bulbs and an iron, one Cookers o. The like. In use, find it a hardship when the counter is set to higher Tariff is also switched over if there is only one or a few during the blocking period The lamps are on, the iron, the stove or the like are not in use. Since (especially with a tariff with a basic fee) the interest

ίο the work is sufficiently preserved, if such Power consumers with their greater power requirement switched off during the blocking period remain, so it is possible to meet the wishes of the customer for continued purchase of their small To accommodate luminous flux at the low tariff even during the blocking period. Man has proposed a double tariff meter with one influenced by the consumption flow Switch to put it in the circuit of the clock controlled, usually to switch on the switch relay for the counter with a voltage winding and to dimension it so that it keeps this circuit open as long as the strength of the consumption current is below a certain level Limit remains and closes it when this limit is reached or exceeded. According to the present invention, for the purpose of continuing to refer to a weak To enable luminous flux at the low tariff even during the blocking period, with one The double tariff meter has a different facility than the one just mentioned offers significant advantages. It is characterized by the fact that the changeover relay is external a voltage winding with insufficient effect for switching is still provided with an additional winding that depends on the consumption current or part of the Consumption current flows through or is fed inductively - and when excited with a certain amperage, the effect of the voltage winding of the relay on that required for switching Measure supplemented.

An exemplary embodiment of the invention is illustrated by the schematic drawing made. 1 represents the base plate of the counter, 2, 2 'are the counting roller sets of the two Counters stored in boards 3, 4. 5 is one mounted at 6 in the board 3 Shaft that is set in rotation by the meter armature, e.g. B. by means of one on her seated gear 7, which with the counter armature, z. B. through a gear ratio, is to be thought coupled. On the shaft 5 there is still a drive 8. By pivoting the Shaft 5, the wheel 8, either as drawn with the gear 9 or with the Gear 10 are brought into engagement with the initial roles of the two counters are connected.

The pivoting of the shaft 5 is caused by the changeover relay, whose armature 11 is connected to the shaft 5. The usual voltage winding sits on the core 12 of the relay formed winding 13, which by lines 14, 15 with the terminals 16,
