Description

Anzeigevorrichtung für Stromunterbrechungen in den Spannungskreisen von Wechselstrom- und Drehstromzählern. Zweck der Erfindung ist, eine möglichst einfache Vorrichtung zu schaffen, die bei Wechsel- und Drehstromzählern jederzeit erkennen läßt, ob die Spannungsspulen unter Strom stehen oder ob der Spannungskreis an irgendeiner Stelle unterbrochen ist.Display device for current interruptions in the voltage circuits of AC and three-phase electricity meters. The purpose of the invention is to create one as possible to create a simple device that works with alternating and three-phase electricity meters at any time shows whether the voltage coils are under current or whether the voltage circuit is interrupted at any point.

Es sind zu diesem Zwecke Anordnungen bekannt, die entweder besondere elektromagnetische Relais oder Sekundärwindungen über der Spannungsspule oder einen Ankcr benutzen, der von dem Spannungseisen angezogen gehalten wird, solange Strom durch die Spannungsspule geht. Diese Einrichtungen sind aber. teils sehr teuer und erhöhen den Eigenverbrauch des Zählers, teils sind sie zu umständlich und zu schwierig anzubringen und unsicher in ihrer Wirkungsweise.There are known arrangements for this purpose that either special electromagnetic relays or secondary windings across the voltage coil or a Use an anchor that is kept attracted to the tension iron as long as there is current goes through the voltage coil. These facilities are however. partly very expensive and increase the meter's self-consumption; in some cases they are too cumbersome and difficult to be attached and uncertain in their mode of operation.

Die Erfindung bringt eine Einrichtung, die auf einfachste und billigste Weise ihren Zweck sicher erfüllt, und zwar wird dazu für jede Spannungsspule eine auf die Frequenz des Stromes abgestimmte Feder an einer solchen Stelle im Zähler angebracht, daß sie bei Stromdurchgang durch die zugehörige Spannungsspule durch deren Einwirkungen in Schwingungen versetzt wird.The invention brings a device that is simplest and cheapest Way, it certainly fulfills its purpose, namely one for each voltage coil Spring tuned to the frequency of the current at such a point in the meter attached that it is carried out when current passes through the associated voltage coil whose effects are set in vibrations.

Die Feder kann entweder mit Teilen, die unter der Einwirkung der zugehörigen Spannungsspule in Erschütterung geraten, mechanisch verbunden sein und dadurch zu Resonanzschwingungen veranlaßt werden (sie kann dabei aus beliebigem Material bestehen) oder sie ist in einem gewissen Abstande vom Spannungseisen bzw. einem Ansatz des Spannungseisens angebracht und aus paramagnetischem Material hergestellt, so daß sie vom Spannungseisen angezogen und abgestoßen wird und so ebenfalls in Schwingungen gerät.The spring can either be associated with parts that are under the action of the Voltage coil get shaken, be mechanically connected and thereby to Resonance vibrations are caused (it can consist of any material) or it is at a certain distance from the tension iron or an attachment of the Tension iron attached and made of paramagnetic material so that it is attracted and repelled by the tension iron and thus also vibrates device.

Um im letzteren Falle die Schwingungen zu vergrößern, ist es sehr vorteilhaft, die Feder zu polarisieren. Dazu kann der Bremsmagnet des Zählers benutzt werden.To increase the vibrations in the latter case, it is very much advantageous to polarize the spring. The counter's brake magnet can be used for this will.

Das eine Ende der Feder ist durch ein Fenster im Zählergehäuse zu sehen und so ausgestaltet, z. B. in Form einer wcißen Fahne, daß man von außen erkennen kann, ob die Feder schwingt oder nicht, ob also die Spannungsspule unter Strom oder der Spannungskreis unterbrochen ist.One end of the spring can be closed through a window in the meter housing see and designed such. B. in the form of a white flag that you can recognize from the outside can determine whether the spring vibrates or not, i.e. whether the voltage coil is energized or the voltage circuit is interrupted.
