Description

Transformator mit üblicher Primär- und Sekundärwicklung GewöhnlicheBetriebstransformatoren haben die Eigenschaft, daß durch die Magnetisierung des Kerns eine nacheilendeBlindleistung erzeugt wird. Da gewöhnlich auf der Belastungsseite des Transformators ebenfalls nacheilende Blindleistungen angeschlossen sind, so ergibt sich, daß im Betrieb ein Transformator im allgemeinen mit stark nacheilendem Strom arbeitet. Die Wirkung der nacheilenden Ströme auf das Netz und den Transformator selber sind bekannt, und man hat sich von jeher bemüht, sie durch neben den Transformator aufgestellte Blindleistungskompensatoren, wie z. B. Kondensatoren, auszugleichen. Gegenüber dieser Einrichtung stellt die Erfindung einen Fortschritt dar, weil sie eine Vereinigung eines Transformators mit einem Kompensator darstellt.Transformer with usual primary and secondary winding Ordinary operating transformers have the property that, due to the magnetization of the core, a lagging reactive power is produced. Usually on the load side of the transformer as well lagging reactive powers are connected, it follows that a Transformer generally works with a strongly lagging current. The effect the lagging currents on the network and the transformer itself are known, and efforts have always been made to place them next to the transformer Reactive power compensators, such as B. capacitors to compensate. Compared to this Facility, the invention represents an advance because it is an association of a transformer with a compensator.

In der Abbildung bedeutet a den wie üblich aufgebauten Kern eines Transformators. Derselbe ist als zweischenkeliger Einphasenkern gezeichnet; man kann jedoch die Erfindung auch bei Manteltransformatoren und Dreiphasentransformatoren verwenden. Die Primärwicklung b und die Sekundärwicklung c sind ebenfalls wie üblich auf die Schenkel gesetzt. IITeu ist eine weitere Vielfachwicklung besonderer Art. Dieselbe entsteht dadurch, daß mehrere konzentrische Zylinder aus Isolationsmaterial abwechselnd mit sehr dünnem Draht links- und rechtsgängig bewickelt werden, ohne daß die einzelnen Lagen galvanisch miteinander verbunden sind, so daß in den Zylindern mit geraden Ordnungszahlen beispielsweise eine Potentialverschiebung nach oben stattfindet, während gleichzeitig in den Zylindern mit ungeraden Ordnungszahlen eine Potentialverschiebung nach unten auftritt. Infolgedessen werden die dielektrischen Schichten zwischen je zwei solchen einlagigen Wicklungen aufgeladen, und die.Ladung vollzieht sich unter gleichzeitigem Erscheinen eines Ladestromes in den feindrähtigen Wicklungen. Der Transformator arbeitet dann so, als wenn er mit einer Kapazität belastet wäre, und man kann je nach den Bedürfnissen entweder die Verhältnisse so einrichten, daß gerade der Leerstrom kompensiert wird, oder auch so, daß ein voreilender Strom fließt.In the figure, a means the core of a built up as usual Transformer. It is drawn as a two-legged single-phase core; man However, the invention can also be used for jacket transformers and three-phase transformers use. The primary winding b and the secondary winding c are also as usual put on the thighs. IITeu is a further multiple development of a special kind. The same is created by the fact that several concentric cylinders made of insulating material be wrapped alternately with very thin wire left and right, without that the individual layers are galvanically connected to each other, so that in the cylinders with even ordinal numbers, for example, there is a potential shift upwards, while at the same time a potential shift in the cylinders with odd ordinal numbers occurs downwards. As a result, the dielectric layers are between two such single-layer windings are charged, and the charge takes place with simultaneous appearance of a charging current in the finely stranded windings. The transformer then works as if it were loaded with a capacity and depending on the needs, one can either arrange the situation so that just the idle current is compensated, or so that a leading current flows.

Durch die Vereinigung wird auch insofern eine Verbilligung ermöglicht, als der Transformator wenigstens in der einen Wicklungshälfte eine kleinere Leistung haben darf, denn bei richtiger Dimensionierung wird der Strom, welcher in. der sekundären Wicklung noch die vektorielle Summe aus Blindstrom und Wirkstrom ist, für die Primärwicklung auf den Wirkstrom beschränkt.The association also makes it possible to reduce the price, than the transformer, at least in one half of the winding, has a lower power may have, because with correct dimensioning the current, which in. the secondary Winding is still the vectorial sum of reactive current and active current for the primary winding limited to the active current.
