Description
Einrichtung, die auf einer Produktbildung unter Ausnutzung eines Effektes beruht, der an einem stromdurchflossenen, magnetisch steuerbaren Widerstandskörper auftritt Zusatz zur Patentanmeldung S41820VIIIb/21d2 (Auslegesdlrift 1 025 504) In der Hauptpatentanmeldung ist eine galvanomagnetische Einrichtung vorgeschlagen, d. h. eine Einrichtung, die auf der Ausnutzung von Effekten beruht, die an stromdurchflossenen Widerstandskörpern unter der Einwirkung magnetischer Felder auftreten. Es ist ausgeführt, daß derartige galvaneenagnetische Einrichtungen sowohl auf der Ausnutzung der Änderung des spezifischen Widerstandes beruhen können, die ein Widerstandskörper durch ein Magnetfeld erfährt, als auch auf der Ausnutzung des sogenannten HallelcFektes. Bei der in der Hauptpatentanmeldung vorgeschlagenen Anordnung werden mehrere Widerstandskörper und ihre zugehörigen Magnetfeldanordnungen als symmetrische zwei- oder mehrphasige Drehstrom-bzw. Drehfeldsysteme derart betrieben, daß die am gemeinsamen Ausgang der Einrichtung entnommene Summe der Produktgrößen ohne die Anwendung von Gleichrichtern als Gleichspannungen bzw. Gleichströme vorliegen. Establishment based on a product formation taking advantage of a The effect is based on a magnetically controllable resistance body through which current flows occurs Addendum to patent application S41820VIIIb / 21d2 (Auslegesdlrift 1 025 504) In the main patent application, a galvanomagnetic device is proposed, d. H. a device that is based on the exploitation of the effects of current flowing through Resistance bodies occur under the influence of magnetic fields. It is executed that such galvaneenagnetische facilities both on the exploitation of the change The resistivity can be based, which a resistance body by a Experienced magnetic field, as well as on the exploitation of the so-called Hallelectect. at the arrangement proposed in the main patent application are several resistance bodies and their associated magnetic field arrangements as symmetrical two or more phase Three-phase or. Rotating field systems operated in such a way that the common output Sum of the product sizes taken from the facility without the use of rectifiers present as direct voltages or direct currents.
Eine derartige Einrichtung eignet sich unter anderem zur Leistungsmessung von Drehströmen und kann beispielsweise an die Stelle eines dreiphasigen Lei stnngsrel ai 5 gesetzt werden. Besonders bei dem letztgenannten Anwendungsfall zeigt es sich aber, daß die am Ausgang der Einrichtung entnommene Summe der Produktgrößen, insbesondere bei der Ausnutzung des Halleffektes zur Produktbildung, nicht ausreicht, um die angeschlossenen Stromkreise. wie z. 13. Regelstromkreise od. dgl., unmittelbar zu steuern. Gemäß der vorliegenden Erfindung wird daher die am Ausgang der Einrichtung entnommene Summe der Produktgrößen als Steuergröße einem an sich bekannten Verstärker zugeführt. Dieser Verstärker kann, wie in der Zeichnung dargestellt ist, ein Röhrenverstärker sein. Es ist jedoch auch möglich, den spannungsverstärkenden Röhrenverstärker durch eine stroinverstärkende Einrichtung, wie beispielsweise einen Magnetverstärker. zu ersetzen. Besonders vorteilhaft ist ein Transistorverstärker. Such a device is suitable, among other things, for power measurement of three-phase currents and can, for example, take the place of a three-phase Lei stngsrel ai 5 can be set. It is particularly evident in the last-mentioned application but that the sum of the product sizes taken at the output of the device, in particular when using the Hall effect for product formation, is not sufficient to achieve the connected circuits. such as 13. Control circuits or the like, directly to steer. According to the present invention, therefore, the output of the device sum of the product variables taken as a control variable from an amplifier known per se fed. As shown in the drawing, this amplifier can be a tube amplifier be. However, it is also possible to use the voltage-boosting tube amplifier a stroine boosting device such as a magnetic booster. to replace. A transistor amplifier is particularly advantageous.
An Hand des in der Zeichnung dargestellten Ausführungsbeispieles sei die Erfindung näher erläutert. Using the exemplary embodiment shown in the drawing the invention is explained in more detail.
Dieses Ausführungsbeispiel entspricht im wesentlichen demjenigen der Fig. 1 der zugehörigen Hauptpatentanmeldung. Drei Hallgeneratoren 1, 2. 3 sind in je einem Magnetfeld angeordnet, welches von den Phasensftömen IR IS, 1T in den Wicklungen 11 12> 13 erzeugt werden. Die Steuerströme der Hallgeneratoren werden jeweils über Transformatoren7, 8, 9 an die drei Phasen eines Drehstromnetzes R, S T angeschlossen. Die Hallspannungen sind sämtlich in Reihe geschaltet und steuern das Gitter einer Elektronenröhre 14> welche ihrerseits die Regel- bzw. Anzeigestromkreise steuert.This embodiment corresponds essentially to that of Fig. 1 of the associated main patent application. Three hall generators 1, 2. 3 are in each a magnetic field arranged, which of the phase currents IR IS, 1T in the windings 11 12> 13 can be generated. The control currents of the Hall generators are respectively Connected via transformers 7, 8, 9 to the three phases of a three-phase network R, S T. The Hall voltages are all connected in series and control the grid of a Electron tube 14> which in turn controls the control or display circuits.
Wie bei der Hauptpatentanmeldung kann auch die Erfindung auf zahlreiche Weise abgewandelt werden, beispielsweise durch Ausnutzung der Widerstandsänderung eines Halbleiterkörpers im Magnetfeld an Stelle des dargestellten Hall effektes. As with the main patent application, the Invention on numerous Modified manner, for example by taking advantage of the change in resistance a semiconductor body in a magnetic field instead of the Hall effect shown.
