Description
Vorrichtung zum Umschalten von Doppeltarifzählern Vorrichtungen zum Umschalten von Doppel-oder Mehrfachtarifzählern u. dgl. Schaltapparaten sind bekannt, leiden aber durchwegs an der Unzuverlässigkeit der sicheren Funktion, da der Schließkontakt infolge der geringen Druckkraft oft versagt.Device for switching double tariff meters Devices for Switching of double or multiple tariff meters and similar switching devices are known. but suffer consistently from the unreliability of the safe function, since the make contact often fails due to the low compressive force.
Diesem Übelstande ist nach der Erfindung dadurch abgeholfen, daß die schwachen, die Funktion auslösenden Ströme auf einen Trennungskontakt wirken, welcher einen genügend starken, bereits vorhandenen Stromkreis öffnet, wodurch im weiteren Verlauf die Umschaltung sicher vor sich gehen muß.This disadvantage is remedied according to the invention in that the weak currents that trigger the function act on an isolating contact, which opens a sufficiently strong, already existing circuit, which in the further The changeover must proceed safely.
Zu diesem Zwecke wird bei der Vorrichtung zum Umschalten von Doppel- oder Mehrfachtarifzählern, bzw. Schaltapparaten zum Schließen und Öffnen von Stromkreisen während bestimmter Zeiten, unter Verwendung eines Zusatzstromes von anderer Beschaffenheit als der Netzstrom, z. B. Überlagerung eines Wechselstromes höherer oder niederer Frequenz bzw. unter Verwendung von zwei oder mehreren Umschalterelais, ein Hauptrelais über einen Trennungskontakt von der Netzspannung ständig erregt, der durch ein Nebenrelais bei Einschalten eines Zusatzstromes getrennt wird und dadurch das eigentliche Umschalterelais unter Strom setzt und so die Umschaltung bewirkt.For this purpose, the device for switching from double or multiple tariff meters or switching devices for closing and opening circuits during certain times, using a supplementary stream of a different nature than the mains current, e.g. B. Superposition of an alternating current higher or lower Frequency or, using two or more changeover relays, a main relay Constantly energized via an isolating contact from the mains voltage, which is triggered by a secondary relay when an additional current is switched on, the actual changeover relay is disconnected energizes and thus causes the switchover.
Als Hauptrelais wird vorteilhaft das Spannungseisen mit der Spannungsspule eines Elektrizitätszählers verwendet.The tension iron with the tension coil is advantageous as the main relay an electricity meter.
In dem Schaltschema ist die Netzleitung mit a und b bezeichnet; parallel zu dieser Leitung liegen die drei Relais NR, HR und UR.In the circuit diagram, the power line is denoted by a and b; parallel the three relays NR, HR and UR are connected to this line.
Das Nebenrelais NR ist so konstruiert und gewickelt, daß dasselbe auf den Netzstrom nicht anspricht und der Hebel Hl am Kontakte K1 liegenbleibt und das Relais HR unter Strom bleibt, wodurch der Kontaktheble1 H2 vom Kontakte 1(2 abgehoben bleibt, so daß das Relais UR stromlos bleibt und den Umschalthebel U nicht betätigt.The secondary relay NR is designed and wound so that the same does not respond to the mains current and the lever Hl remains on the contact K1 and the relay HR remains energized, whereby the contact lever 1 H2 from contact 1 (2 remains lifted, so that the relay UR remains de-energized and the switch lever U does not actuated.
Wirkt auf das Nebenrelais NR ein über die Leitung a und b oder durch eine Separatleitung kommender entsprechender Strom ein, so daß das Relais NR zum Ansprechen gebracht wird, so hebt das Relais den Kontakt bei K1 auf, das Relais HR wird stromlos, schließt den Kontakt K2, wodurch das Relais UR sofort anspricht und den Umschalthebel U betätigt und die gewünschte Umschaltung vornimmt.If the secondary relay NR is affected by a corresponding current coming via the lines a and b or a separate line, so that the relay NR is made to respond, the relay removes the contact at K1, the relay HR is de-energized and closes the contact K2, whereby the relay UR responds immediately and actuates the changeover lever U and makes the desired changeover.
