Description
Die Erfindung betrifft eine Spule mit einer Wicklung aus einer Anzahl von aus mehreren gegeneinander isolierten, miteinander verdrillten Litzendrähten bestehenden schlauchförmigen Leitersträngen, wobei die einzelnen Leiterstränge derart angeordnet sind, daß sie ihre Lage zueinander soweit wechseln, daß diese mindestens auf die Läoge eircr Windung jeweils jede mögliche geometrische Lage zur Schlauchachse einnehmen und die schlauchförmigen S liter im Querschnitt in die Form eines Rechtecks zusammengepreßt sind.The invention relates to a coil with a winding of a number of several against each other insulated, twisted-together stranded wires consisting of tubular conductor strands, the individual conductor strands are arranged in such a way that they change their position to one another so far that this Take at least every possible geometric position to the hose axis to the length of one turn and the tubular S liter are compressed into the shape of a rectangle in cross section.
Eine derartige Spule ist aus dem Buch Nottebrock »Spulen«, 1950, als Bauelement der Nachrichtentechnik, d.h. für Hochfrequenz- und Niederfrequenzspulen bekanntgeworden.Such a coil is from the book Nottebrock »Spulen«, 1950, as a component of communications engineering, i.e. became known for high frequency and low frequency coils.
Die US-PS 5 87 764 zeigt die Zusammensetzung einzelner Leiterstränge aus gegeneinander isolierten, miteinander verdrillten Litzendrähten und das aus mehreren Leitersträngen ein Leiter hergestellt werden kann, der in die Form eines Rechtecks zusammengepreßt werden kann.The US-PS 5 87 764 shows the composition of individual strands of conductor insulated from one another, stranded wires twisted together and that a conductor can be produced from several conductor strands which can be compressed into the shape of a rectangle.
Es Aufgabe der Erfindung, eine elektrische Spule als Kommutierungsdrossel für Stromrichteranlagen derart zu verbessern, daß der Stromverdrängungseffekt und damit die Stromwärmeverluste verringerl werden, Weiterhin soll die Spule mit relativ geringen Kosten hergestellt werden können,It is the object of the invention to provide an electrical coil as To improve commutation choke for power converter systems so that the current displacement effect and so that the current heat losses are reduced. Furthermore, the coil should have a relatively low cost can be produced
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.
bei der Verwendung für Stromrichter bei elektrischenwhen used for converters in electrical
da die Kühlanlage für die Abführung der Stromwärmeverlusfe kleiner sein kann. Außerdem wird derbecause the cooling system for the dissipation of the electricity heat losses can be smaller. In addition, the
ίο Wirkungsgrad der Gesamtanlage verbessert.ίο Improved efficiency of the overall system.
Für einen Leiterquerschnitt von 50 mm2 werden z. B. 132 Drähte mit einem Durchmesser von 0,1 mm nach ihrer Lackisolierung miteinander verdrillt, so daß Stränge mit einem effektiven Querschnitt von ca. 1 mm2 is vorliegen. Dann werden etwa 50 solcher Stränge schlauchförmig miteinander verwoben, um anschließend auf einen Querschnitt von ca. 25 - 4 mm2 gedrückt zu werden. Mit diesem flexiblen Leiter lassen sich alle Arten von Spulen, z. B. scheiben- oder zylmderförmige Spulen leicht wickeln.For a conductor cross-section of 50 mm 2 z. B. 132 wires with a diameter of 0.1 mm twisted together after their enamel insulation, so that strands with an effective cross-section of about 1 mm 2 is present. About 50 such strands are then woven together in the form of a hose, in order to then be pressed onto a cross-section of approx. 25-4 mm 2. With this flexible conductor all types of coils, z. B. easily wind disc or cylindrical coils.
Es können in einer Weiterbildung der Erfindung mehrere schlauchförmige oder rechteckige Leiter konzentrisch zueinander angeordnet sein.It can in a development of the invention several tubular or rectangular conductors can be arranged concentrically to one another.
Die Drosselspule nach der Erfindung kann sowohl eisenlos als auch mit einem geblechten Eisenkern versehen sein.The choke coil according to the invention can be either ironless or with a laminated iron core be provided.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus dem im folgenden beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiel. Es zeigtFurther details and advantageous developments of the invention emerge from the following embodiment described and shown in the drawing. It shows
Fig.2 einen zu einem rechteckigen Querschnitt zusammengedrückten Leiter.2 shows a conductor compressed to a rectangular cross-section.
In der Zeichnung F i g. 1 sind die parallel verlaufenden Leiterstränge mit 10, 11, 12 ... 17 und die mit diesen verflochtenen ebenfalls parallel verlaufenden Leiterstränge mit 20, 21, 22 bezeichnet. Im unteren Teil der F i g. 1 ist einer der verdrillten Leiterstränge aufgefächert dargestellt. Der Verflechtungswinkel ist so gewählt, daß die einzelnen Leitprstränge ihre Lage am Umfang des Schlauches jeweils so wechseln, daß sie mindestens auf die Länge einer Windung jeweils jede mögliche räumliche Lage zur Schlauchachse einnehmen. Es ergeben sich hierbei ähnlich günstige Verlustwerte wie bei einem sogenannten Roebel-Stab einer elektrischen Maschine, der im räumlichen Aufbau jedoch von der Spule nach der Erfindung abweicht.In the drawing F i g. 1 are the parallel strands with 10, 11, 12 ... 17 and those with these intertwined conductor strands, which also run parallel, are denoted by 20, 21, 22. In the lower part of the F i g. 1 one of the twisted conductor strands is shown fanned out. The interweaving angle is like this chosen that the individual Leitprstränge their position on Change the circumference of the hose so that they are at least the length of one turn each assume possible spatial position to the hose axis. This results in similarly favorable loss values as with a so-called Roebel rod of an electrical machine, but the spatial structure of differs from the coil according to the invention.
In der Fig.2 ist der aus den Leitersträngen geflochtene Schlauch zu einem rechteckigen Querschnitt zusammengedrückt. Diese Leiter werden dann zu entsprechenden Windungen von Spulen gewickelt.In Fig.2 is the one from the conductor strands braided hose compressed into a rectangular cross-section. These leaders then become wound into corresponding turns of coils.
