Description

Einrichtung zum Entnehmen der für Rundfunkapparate benötigten elektrischen Energie aüs dem Lichtnetz Die Erfindung bezieht sich auf Netzanschlußgeräte zur Entnahme von Heiz- und Anodenstrom für Rundfunkapparate und bezweckt, Geräte dieser Art so auszubilden, daß auf einfache Art die Spannungsschwankungen im Lichtnetz ausgeglichen werden. Es ist bereits bekannt, parallel zu den Entnahmestellen des Stromes Akkumulatoren zu schalten, welche als Puffer für die auftretenden Spannungsschwankungen zu dienen vermögen. Es empfiehlt sich, solche Akkumulatoren nur an der Entnahmestelle für den Heizstrom der Kathodenröhren zu verwenden und an den Entnahmestellen für den Anodenstrom die Spannungsschwankungen des Lichtnetzes in an sich bekannter Weise durch Siebketten auszugleichen. Man kann aber auch die Entnahmestellen für den Anodenstrom in gleicher Weise mit Akkumulatoren verbinden. Hierbei dienen die Akkumulatoren als Puffer für die,Schwankungen der Netzspannung. Die Anzahl der Batteriezellen muß hierbei so groß gewählt werden, daß die Gesamtspannung der Batterie der zu entnehmenden Spannung entspricht, so daß die periodischen überspannungen im Netz zum Aufladen der Batterie verwendet und das periodische Sinken der Netzspannung durch Entladungen der Batterie ausgeglichen wird.Device for removing the electrical equipment required for radio sets Energy from the lighting network The invention relates to network connection devices for Removal of heating and anode current for radio sets and the purpose of these devices Kind to train so that in a simple way the voltage fluctuations in the lighting network be balanced. It is already known, parallel to the tapping points of the Stromes accumulators to switch, which as a buffer for the occurring voltage fluctuations able to serve. It is advisable to only use such accumulators at the extraction point to use for the heating current of the cathode tubes and at the tapping points for the anode current the voltage fluctuations of the lighting network in a manner known per se to be compensated by sieve chains. But you can also use the tapping points for the anode current Connect to accumulators in the same way. The accumulators are used here as a buffer for fluctuations in the mains voltage. The number of battery cells must be chosen so large that the total voltage of the battery to be taken Voltage corresponds, so that the periodic surges in the network for charging of the battery and the periodic drop in mains voltage caused by discharges the battery is balanced.

Es hat sich herausgestellt, daß die bekannten Bleiakkumulatoren für solche Zwecke weniger geeignet sind, weil in den Bleiakkumulatoren sehr komplizierte Vorgänge stattfinden, die durch chemische Nebenprozesse bedingt sind und sich als akustische Störungen äußern.It has been found that the known lead-acid batteries for Such purposes are less suitable because the lead-acid batteries are very complicated Processes take place that are caused by secondary chemical processes and are identified as express acoustic disturbances.

Um in den Akkumulatorenzellen das Aufsteigen von Gasblasen infolge von Lberladung zu verhindern, werden die Zellen zweckmäßig bei Nichtgebrauch kurzgeschlossen. Auch hierzu wären Bleiakkumulatoren nicht verwendbar, weil ein vollständiges Entladen von Bleiakkumulatoren zur Zerstörung der Bleielektroden führen würde.In order to cause gas bubbles to rise in the accumulator cells To prevent overcharging, the cells are expediently short-circuited when not in use. Lead-acid batteries cannot be used for this either, because they are completely discharged lead-acid batteries would destroy the lead electrodes.

Erfindungsgemäß werden als Akkumulatoren solche verwendet, bei welchen Nickel-und Kadmiumelektroden in Kalilauge eintauchen. Solche Zellen liefern in Pufferschaltung eine vollständig gleichmäßige Spannun- ; sie haben auch den Vorteil, daß sie beim Kurzschließen keinen Schaden nehmen. Da Zellen dieser Art im Moment des Einschaltens vollständig ungeladen sind und da ein etwaiger Ladungsüberschuß bei Nichtgebrauch durch das Kurzschließen vernichtet wird, so kann eine Gasbildung an solchen Akkumulatoren bei vorschriftsmäßiger Behandlung nicht eintreten, so daß es möglich ist, jede Zelle der Batterie in einem dicht verschlossenen Gehäuse unterzubringen. Hierdurch ergibt sich der weitere Vorteil, daß die Zellen beim Transport, beim Schrägstellen oder Umlegen oder bei Erschütterungen nicht auslaufen-.-imd e daß sie auch in der Schräglage ihren. Dienst verrichten.According to the invention, those are used as accumulators in which Immerse the nickel and cadmium electrodes in potassium hydroxide solution. Such cells supply in a buffer circuit a completely uniform tension; they also have the advantage of being at Short-circuiting will not be damaged. Because cells of this type at the moment of switching on are completely uncharged and there is a possible excess charge when not in use is destroyed by short-circuiting, gas can form on such accumulators if handled properly, it does not occur, so that it is possible for every cell the battery in a tightly sealed housing. This results in the further advantage that the cells during transport, when inclined or Turn it over or do not run out in the event of vibrations -.- and that it is also in the inclined position their. Perform service.

Die chemischen Vorgänge beim Laden solcher Nickel-Kadmium-Akkumulatoren lassen sich durch die folgenden chemischen Formeln ausdrücken: 2KOH=2K+20H 2K+2H20=2KOH-E-H2 20H =H20--0 2 Ni (O H) 2 + 0 =N1203 -@- 2 ISO Cd (OH) 2 + H2 - Cd -f- 2 H20. Beim Entladen finden in bekannter Weise die entgegengesetzten Vorgänge statt. .The chemical processes involved in charging such nickel-cadmium batteries can be expressed using the following chemical formulas: 2KOH = 2K + 20H 2K + 2H20 = 2KOH-E-H2 20H = H20--0 2 Ni (OH) 2 + 0 = N1203 - @ - 2 ISO Cd (OH) 2 + H2 - Cd -f- 2 H20. When unloading, the opposite processes take place in a known manner. .

Um solche Akkumulatorenbatterien handlicher zu gestalten, kann man gegebenenfalls die einzelnen geschlossenen Zellen noch zusammen in einem gemeinsamen, ebenfalls dicht verschlossenen Gehäuse unterbringen. Der Erfindungsgegenstand hat gegenüber den bekannten Netzanschlußgeräten den erheblichen Vorteil, daß er die Verwendung von Batterien vollständig überflüssig macht, so daß nicht nur der Anoden-, sondern auch der Heizstrom unmittelbar dem Netz entnommen werden kann.To make such accumulator batteries more manageable, one can possibly the individual closed cells still together in a common, also place tightly closed housing. The subject of the invention has compared to the known power supply units the significant advantage that it has the Completely eliminates the need for batteries, so that not only the anode, but also the heating current can be taken directly from the network.
