Description

Schaltung in Relaiskreisen von Induktionszählern In vielen elektrischen Apparaten für Wechselstrom befinden sich Relaiskreise, in welchen die Relais selbst nicht für die volle Spannung gewickelt werden können. Selbst wenn man zu solch dünnen Drahtstärken greift, welche eine mechanische Sicherheit fraglich :erscheinen lassen, so wird es doch nötig, Vorschaltwiderstände anzuordnen. Diese Vorschaltwiderstände vergrößern den Wattverbrauch der Relaiskreise, ohne daß sie die Funktion der Relais irgendwie begünstigen. Im Gegenteil ist die Wärme, welche durch die Relais erzeugt wird, unter Umständen nachteilig für die im gleichen Gehäuse eingebauten Apparate oder Apparateteile.Circuit in relay circuits of induction meters In many electrical Devices for alternating current are relay circuits in which the relays themselves cannot be wound to full tension. Even if you are too thin Wire sizes take effect, which make mechanical security questionable: appear, so it becomes necessary to arrange series resistors. These series resistors increase the watt consumption of the relay circuits without affecting the function of the relay favor somehow. On the contrary is the heat generated by the relays may, under certain circumstances, be detrimental to the devices installed in the same housing or parts of apparatus.

Die nachstehende Erfindung soll diese ÜbeIstände vermeiden. Nach derselben werden bei Spannungen, welche nicht mehr unmittelbar an das Relais angelegt werden können, kleine Autotransformatoren vorgesehen. Das Relais . wird an einem Teil der Wicklung angelegt, währenddem an die gesamte Wicklung die vorhandene Spannung angeschlossen wird. Durch diese Anordnung ist, namentlich bei höheren Spannungen, :eine wesentliche Reduktion in der Umsetzung von :elektrischer Leistung in Wärme im Relaiskreis ermöglicht. Es besteht aber noch ferner der Vorteil, daß nun die Relaisspule für eine verhältnismäßig kleine Spannung gewickelt werden kann. Dadurch ist die Verwendung von dickerem Draht möglich, der eine solidere Ausführung der Spule gewährleistet. überdies kann der Wickelraum der Spule besser ausgenutzt werden, da der dickere Draht gegenüber dem dünneren eine wesentlich bessere Ausnutzung des Wickelraumes ergibt.The following invention is intended to avoid these inconveniences. After the same are used in the event of voltages that are no longer directly applied to the relay can, small autotransformers provided. The relay. will be part of the Winding applied, while the existing voltage is connected to the entire winding will. Due to this arrangement, especially at higher voltages,: is essential Reduction in the conversion of: electrical power into heat in the relay circuit enabled. But there is also the advantage that now the relay coil for a relatively small tension can be wound. This means the use of thicker wire possible, which ensures a more solid design of the coil. moreover, the The winding space of the coil can be better used because the wire is thicker than the thinner results in a much better utilization of the changing room.

In nachstehendem Beispiel ist eine bezügliche Schaltung in einem Tarifzähler für Wechselstrom angedeutet.The following example shows a related circuit in a tariff meter indicated for alternating current.

i ist die Stromspule, z die Spannungsspule. Mit 3 ist der Autotransformator bezeichnet, wobei 4. die Teilwicklung bedeutet, an welche das Relais, angeschlossen wird. 5 ist die Relaiswicklung. Die Relaiswicklung kann irgendeinem Tarif- oder andern Apparat angehören, wie z. B. einem Doppeltarif-, Dreifachtarif-iVIax-imumzählwerk, Brems-oder Stopprelais. Der eine Anschluß des Autotransformators ist mit dem einen Pol der Leitung verbunden, währenddem der andere Anschluß über ein-3n Steuerapparat 6, z. B. eine Tarifuhr, führt.i is the current coil, z the voltage coil. With 3 is the autotransformer denotes, where 4. means the partial winding to which the relay is connected will. 5 is the relay winding. The relay winding can have any tariff or belong to another device, such as B. a double tariff, triple tariff iVIax imum indexing unit, Brake or stop relay. One connection of the autotransformer is with one Pole of the line connected, while the other connection has a control unit 6, e.g. B. a tariff clock leads.
