Description

DEUTSCHESGERMAN

Zur selbsttätigen Regelung der Impedanz eines Wechselstromkreises, d. h. des Verhältnisses von Spannung zu Strom, wurden bisher vielfach Waagebalken-Meßwerke verwendet, bei denen ein Spannungs- und ein Strommeßwerk an den beiden Enden eines Waagebalkens angriffen und diesen bei dem richtigen Impedanzwert in einer Mittelstellung hielten.For automatic control of the impedance of an alternating current circuit, i. H. the ratio of Voltage to current, balance beam measuring units have so far been used in many cases, in which a voltage and attacked a current meter at the two ends of a balance beam and this at the held correct impedance value in a middle position.

Ferner hat man schon Drehspul- oder Tauchspulmeßwerke verwendet, deren Steuerspule nach Art der Quotientenmesser zwei Wicklungen aufwies, von denen die eine durch eine von dem Verbraucher-Wechselstrom und die andere durch eine von der Speise-Wechselspannung des zu regelnden Kreises abgeleitete Gleichspannung beaufschlagt wurde, derart, daß die Verstellung des Meßwerkes der Differenz der Einstellmomente entsprach.Moving coil or moving coil measuring units have also been used, the control coil of which is of the type The quotient meter had two windings, one of which by one of the consumer alternating current and the other by one of the AC supply voltage of the circuit to be regulated derived DC voltage was applied in such a way that the adjustment of the measuring mechanism of the difference which corresponded to the setting torques.

Demgegenüber wird für selbsttätige Impedanzregler mit Drehspul- oder Tauchspulmeßwerk eine einfachere Schaltungsanordnung vorgeschlagen, bei der erfindungsgemäß die Steuerspule des Reglermeß- ao Werkes nur eine Wicklung trägt, die von einer aus den beiden Gleichspannungen gebildeten Differenzspannung beaufschlagt wird.In contrast, a simpler one is used for automatic impedance regulators with moving-coil or moving-coil measuring mechanisms Circuit arrangement proposed in which, according to the invention, the control coil of the Reglermeß- ao Movement carries only one winding, which is a difference voltage formed from the two DC voltages is applied.

Diese beiden Gleichspannungen werden beim Sollwert der Impedanz auf die Differenz Null abge- glichen. Sobald eine Abweichung von diesem Sollwert auftritt, wird die eine oder die andere Spannung überwiegen und ein entsprechender Differenzstrom fließen, der je nach seiner Polarität das Meß werk in dem einen oder dem anderen Sinne verstellt, wodurch eine Herauf- bzw. Herabsetzung des Impedanzwertes ausgelöst wird.These two DC voltages are reduced to the difference zero at the setpoint of the impedance. resembled. As soon as a deviation from this nominal value occurs, one or the other voltage will predominate and a corresponding differential current flow, depending on its polarity, the measuring plant in the adjusted one or the other sense, whereby an increase or decrease of the impedance value triggered will.

In dem abgebildeten Ausführungsbeispiel der erfindungsgemäßen Schaltungsanordnung sind 1 und 2 die beiden AVechselstrom-Speiseleitungen, an welche der in seiner Impedanz zu regelnde Verbraucher angeschlossen zu denken ist. 3 ist ein Stromwandler und 4 ein Spannungswandler; beide dienen dazu, die Regelschaltung von den Speiseleitungen 1 und 2 galvanisch zu trennen. Außerdem sind diese Wandler so bemessen, daß aus dem Verbraucher-Wechselstrom und aus der angelegten Speise-Wechselspannung zwei Wechselspannungen (beispielsweise Niederspannungen) vergleichbarer Größe abgeleitet werden. Diese abgeleiteten Wechselspannungen werden durch die Graetz-Gleichrichter 5 und 6 in Gleichspannungen umgewandelt. 7 ist die Steuerspule eines Reglermeßwerkes; diese wird durch die beiden Gleichspannungen gegensinnig beaufschlagt, so daß immer nur deren Differenzbetrag wirksam wird. 8 ist ein Belastungswiderstand für den Graetz-Gleichrichter 5. Ebenso ist für den Graetz-Gleichrichter 6 ein Belastungswiderstand 9 vorgesehen, der zugleich als einstellbarer Spannungsteiler ausgebildet ist. An diesem Span-Schaltungsanordnung für selbsttätige
ImpedanzreglerIn the illustrated embodiment of the circuit arrangement according to the invention, 1 and 2 are the two AC supply lines to which the consumer whose impedance is to be connected is to be thought of. 3 is a current converter and 4 is a voltage converter; Both serve to galvanically separate the control circuit from the feed lines 1 and 2. In addition, these converters are dimensioned in such a way that two alternating voltages (for example low voltages) of comparable magnitude are derived from the consumer alternating current and the applied alternating supply voltage. These derived alternating voltages are converted into direct voltages by the Graetz rectifiers 5 and 6. 7 is the control coil of a regulator measuring mechanism; this is acted upon in opposite directions by the two DC voltages, so that only the difference between them is effective. 8 is a load resistor for the Graetz rectifier 5. Likewise, a load resistor 9 is provided for the Graetz rectifier 6, which at the same time is designed as an adjustable voltage divider. On this chip circuit arrangement for automatic

nungsteiler wird die eine der zur Differenzbildung herangezogenen Gleichspannungen, im vorliegenden Falle die aus der Speise-Wechselspannung abgeleitete, abgegriffen. Durch entsprechende Einstellung des Spannungsteilers 9 wird diese Gleichspannung so bemessen, daß bei Erreichung des Sollwertes der Impedanz die Differenz der beiden Gleichspannungen gerade Null ist. Mittels des einstellbaren ohmschen Vorwiderstandes 10, der vor die Meßwerkspule 7 geschaltet ist, läßt sich die Ansprechempfindlichkeit des Meßwerkes nach Bedarf verändern.The voltage divider is one of the DC voltages used to form the difference, in the present case Case the derived from the AC supply voltage, tapped. By setting the Voltage divider 9, this DC voltage is dimensioned so that when the target value of the impedance is reached the difference between the two DC voltages is just zero. By means of the adjustable ohmic series resistor 10, which is connected in front of the measuring mechanism coil 7, the sensitivity of the measuring mechanism change as needed.
