Description
Der Wirkungsgrad eines elektrischen Transformators ist von wesentlicher Bedeutung bei der Umwandlung von Energie. Die Reduzierung der sogenannten "Kupfer- und Eisenverluste" und andere bekannte Maßnahmen können den Wirkungsgrad nicht wesentlich verbessern.The efficiency of an electrical transformer is essential Importance in the conversion of energy. The reduction the so-called "copper and iron losses" and other known ones Measures cannot significantly improve efficiency.
Der in Anspruch 1 gegebenen Erfindung liegt das Problem zugrunde, den Wirkungsgrad des Transformators wesentlich zu erhöhen. Durch die Unterdrückung bzw. Reduzierung der elektromagnetischen Rückkopplung auf die Primärphase, also den Primärleiter, des Transformators wird dies erreicht.The invention given in claim 1 is based on the problem to significantly increase the efficiency of the transformer. By the suppression or reduction of electromagnetic feedback on the primary phase, i.e. the primary conductor, of the transformer this is achieved.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, indem Primärphase, Sekundärphase und Kern des Transformators koaxial angeordnet werden.This object is achieved according to the invention in that Primary phase, secondary phase and core of the transformer coaxial to be ordered.

Die Primärphase 11 und Sekundärphase 12, vorzugsweise aus Kupfer, sind koaxial angeordnet. Diese Leiter 11 und 12 sind induktiv durch ein geeignetes magnetisch leitfähiges Medium 13 verbunden. Je nach Frequenz- und Einsatzbereich kann dieses Medium Stahl, Transformator-Blech, Ferrit, Luft, usw. sein. Die koaxialen Transformatorteile 11, 12 und 13 sind galvanisch durch elektrische Isolatoren 14, 15 und 16 aus elektrisch nicht-leitendem Material getrennt. Die koaxiale Anordnung des Transformatorkerns 13 zwischen der Primärphase 11 und Sekundärphase 12, bewirkt eine Reduzierung der elektromagnetischen Rückkopplung auf die Primärphase 11 bei Abgabe von elektrischer Energie durch die Sekundärphase 12. Hierdurch wird der Wirkungsgrad bei der elektromagnetischen Energieumwandlung wesentlich verbessert.The primary phase 11 and secondary phase 12 , preferably made of copper, are arranged coaxially. These conductors 11 and 12 are connected inductively by a suitable magnetically conductive medium 13 . Depending on the frequency and application area, this medium can be steel, transformer sheet metal, ferrite, air, etc. The coaxial transformer parts 11 , 12 and 13 are galvanically separated by electrical insulators 14 , 15 and 16 made of electrically non-conductive material. The coaxial arrangement of the transformer core 13 between the primary phase 11 and the secondary phase 12 brings about a reduction in the electromagnetic feedback to the primary phase 11 when electrical energy is emitted by the secondary phase 12 . This significantly improves the efficiency of electromagnetic energy conversion.
Fig. 2 zeigt das Prinzipschaltbild des koaxialen Transformators. Wird eine elektrische Wechsel- oder Pulsspannung an den Eingang 23 des koaxialen Transformators angelegt, so fließt ein entsprechender elektrischer Strom durch die Primärleiter 21. Durch Induktion wird eine elektrische Spannung in dem Sekundärleiter 22 erzeugt und steht am Transformator-Ausgang 24 zur Verfügung. Fig. 2 shows the basic circuit diagram of the coaxial transformer. If an electrical AC or pulse voltage is applied to the input 23 of the coaxial transformer, a corresponding electrical current flows through the primary conductor 21 . An electrical voltage is generated in the secondary conductor 22 by induction and is available at the transformer output 24 .
Koaxiale Transformatoren können vorzugsweise als Stäbe oder Stangen hergestellt werden. Bei Bedarf und je nach gewünschter Spannung und Strom, können diese Stäbe zu einer "Transformatoren Batterie" geschaltet werden. Coaxial transformers can preferably be used as rods or Rods are made. If necessary and depending on the desired Voltage and current, these rods can become a "transformers Battery ".
Fig. 3 zeigt vier koaxiale Transformatoren, deren Primärleiter und Sekundärleiter in Reihe geschaltet sind. Fig. 3 shows four coaxial transformers, the primary conductors and secondary conductors are connected in series.
Fig. 4 zeigt vier koaxiale Transformatoren, deren Primärleiter in Reihe und deren Sekundärleiter parallel geschaltet sind. Fig. 4 shows four coaxial transformers whose primary conductors are connected in series and whose secondary conductors are connected in parallel.
Koaxiale Transformatoren können auch als Mehrphasen-Transformatoren geschaltet werden. Fig. 5 zeigt einen 3-Phasen- Transformator in Stern-Schaltung und Fig. 6 zeigt einen 3-Phasen- Transformator in Dreieck-Schaltung. Durch Schaltung von vorgefertigten Stäben wird eine große Flexibilität in der Herstellung erreicht.Coaxial transformers can also be switched as multi-phase transformers. Fig. 5 shows a 3-phase transformer in a star connection and Fig. 6 shows a 3-phase transformer in a delta connection. By switching prefabricated bars, great flexibility in production is achieved.
Eine weitere Ausführungsform der Erfindung besteht darin, daß der Sekundärleiter vorzugsweise aus Stahl oder aus einem anderen geeigneten magnetisch und elektrisch leitfähigem Material hergestellt wird. Hierdurch wird die Funktion des Transformatorkerns mit übernommen bzw. ersetzt durch den Sekundärleiter.Another embodiment of the invention is that the Secondary conductor preferably made of steel or another suitable magnetically and electrically conductive material becomes. As a result, the function of the transformer core with taken over or replaced by the secondary leader.
