Description

Einrichtung zur Erzielung einer konstanten Verbraucher-Wechselspannung bei schwankender Netzspannung und sich ändernder Belastung Im Patent 728 296 wird eine Einrichtung zur Erzielung einer konstanten Verbraucher-Wechselspannung bei schwankender Netzspannung und sich ändernder Belastung unter Verwendung einer vorgeschalteten Drosselspule und einer Brückenschaltung geschützt, bei der die Primärwicklung eines den. Verbraucher speisenden - Transformators zwei Zweige einer Brückenschaltung bildet, in denen beiden anderen Zweigen eine Re@geldrosselspule mit einem zu dieser parallel geschalteten Kondensator und ein Ohmscher Widerstand eingeschaltet sind. In dem Mittelzweig liegt ein Gleichrichter, der Vormagnetisierungs.wicklungen auf der Regeldrosselspule und dem Transformator speist.Device for achieving a constant AC consumer voltage with fluctuating mains voltage and changing load In patent 728 296 a device for achieving a constant AC consumer voltage fluctuating mains voltage and changing load using an upstream Choke coil and a bridge circuit protected, in which the primary winding of a the. Consumers feeding - transformer two branches of a bridge circuit forms, in which two other branches a Re @ geld choke coil with one to this capacitor connected in parallel and an ohmic resistor are switched on. In the middle branch there is a rectifier, the bias windings the regulating reactor and the transformer.

Gemäß der Erfindung ist nur die in dem einen Brückenzweig eingeschaltete Regeldrosselspule mit einer Vormagnetisierungswicklung ausgerüstet, welche von dem gleichgerichteten Wechselstrom gespeist wird, den der im Mittelzweig der Brücke liegende Gleichrichter liefert.According to the invention, only that is switched on in one branch of the bridge Regulating reactor equipped with a bias winding, which is controlled by the rectified alternating current is fed, the one in the middle branch of the bridge lying rectifier supplies.

Eingehende Versuche haben nämlich gezeigt, daß eine solche Bemessung der in dem einen Brückenzweig eingeschalteten Drosselspule und ihres Parallelkon densato,i~s möglich ist, da.ß die Steuerung des Blindsträmes zum Spannungsausgleich in Verbindung mit der Brückenschaltung allein mit Hilfe dieser Drosselspule: durchgeführt wird. Wegen des in dieser Drosselspule erfolgenden größeren Energieumsatzes braucht sie nur etwas reich.-licher bemeissen zu werden, als es bei der Anordnung des Hauptpatents notwendig ist. Dadurch wird die Gleichstromvo@rrnagnetisie!-rungswicklung auf dem Transformator überflüssig, so daß eine wesentliche Vereinfachung und Verbesserung gegenüber dem Hauptpatent erreicht wird. Während nämlich bei der Anordnung nach dem Hauptpatent ein dreischenkliger Transformator mit je einer Magnetisierungswicklung auf den beiden :l#,ußenschenlzeln notwendig ist, ist bei der neuen Anordnung nur noch ein einfacher Manteltransformator erforderlich. Dieser Ersparnis am Transformator steht nur ein geringfügiger Mehraufwand bei der etwas größer gewählten Drosselspule des einen Brückenzweiges gegenüber.In-depth tests have shown that that one such dimensioning of the inductor switched on in one branch of the bridge and their parallel condensation, it is possible that the control of the blind currents to the Voltage equalization in connection with the bridge circuit alone with the help of this Choke coil: is carried out. Because of the larger one taking place in this choke coil In terms of energy expenditure, it only needs to be a little more abundant than it is is necessary when arranging the main patent. This causes the direct current pre-magnetization winding on the transformer superfluous, so that a substantial simplification and improvement compared to the main patent is achieved. While namely with the arrangement after the main patent a three-legged transformer with one magnetizing winding each on the two: l #, outer leg is necessary, is with the new arrangement only a simple jacket transformer is still required. This saving on the transformer there is only a slight additional effort for the slightly larger choke coil of the one branch across the bridge.
