The windings consists of magnetic strip or wire material. They are wound in a plane which is at right angles to the plane which is at winding (2). The windings of the magnetic frame, which consists of dynamo strips, are wound edgewise in the plane of the support. The individual turns are separated by a given distance. The thickness can be varied according to requirements.

Description

Elektrische Drosselspule, insbesondere Glättungsirossel Die Erfindung betrifft eine elektrische Drosselspule, insbesondere Glättuzzgsdrossel, mit einer eisenkerniosen, hohlzylinb derförmigen Erregerwicklung, die von einem als Blechpaketrahmen ausgeführten magnetischen Rückschluß umgeben ist. Eine derartige Drosselspule ist aus den Big. 1 und 2 der DZ AUS 1 538 136 bekannt. Bei dieser bekannten Drosselspule ist der Blechpaketrahmen aus gestanzten Blechen aufgebaut, die mechanisch miteinander verbunden werden müssen, z.B. durch isolierte Spannbolzen und Druckplatten.Electric choke coil, particularly smoothing iron The invention relates to an electrical choke coil, in particular smoothing choke, with a Iron-core, hollow cylinder-shaped excitation winding, which is held by a laminated core frame executed magnetic yoke is surrounded. One such choke coil is from the big. 1 and 2 of DZ AUS 1 538 136 known. In this known choke coil the laminated core frame is made up of punched metal sheets that are mechanically interconnected must be connected, e.g. by means of insulated clamping bolts and pressure plates.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, durch eine besondere Formgebung des Blechpaketrahmens seine Perti; gung zu vereinfachen. Zur Lösung dieser Aufgabe besteht gemäß der Erfindung der Blechpaketrahmen aus mehreren, auf einem Isolierkörper nebeneinander liegend angeordneten Wicklungen aus magnetischem band- oder drahtförmigem Material, deren Wicklungsebene senkrecht zu der Wicklungsebene der Erregerwicklung liegt. Bei einem derartig aus mehreren Wicklungen aufgebauten Blechpaketrahmen entfällt das Stanzen von Einzeiblechen, so daß keine Schnittwerkzeuge für die Bleche erforderlich sind.The present invention is based on the object by a special shape of the laminated core frame his Perti; to simplify the process. To the According to the invention, the solution to this problem consists of several laminated core frames, Magnetic windings arranged side by side on an insulating body strip or wire-shaped material, the winding plane of which is perpendicular to the winding plane the excitation winding. In the case of such a structure composed of several windings There is no need to punch single sheets, so there are no cutting tools are required for the sheets.

Es entfallen weiterhin sämtliche mechanischen Befestigungselemente, da die einzelnen Nticklungen des Blechpaketrahmens auf einem Isolierstoffkörper angeordnet sind. Dieser Isolierstoffkörper hat entsprechend der Form des Blechpaketrahmens einen rechteckigen inneren Hohlraum, in welchem die Brregerllick.lung der Drosselspule liegt. Auf diese Weise dient der Isolierstoffkörper gleichzeitig als Luftführungskanal und Eisenisolierung für die Wicklung. Durch entsprechende konstruktive Gestaltung und mechanische Bemessung kann der Isolierstoffkörper auch als tragendes Element eingesetzt werden.There are still no mechanical fastening elements, because the individual Nticklungen of the laminated core frame on an insulating body are arranged. This insulating body has the shape of the laminated core frame a rectangular inner cavity in which the Brregerll.lung the Choke coil is located. In this way, the insulating body also serves as Air duct and iron insulation for the winding. Through appropriate constructive The insulating body can also be used as a load-bearing structure and mechanical dimensioning Element are used.

Da die Wicklungsebene des Blechpaketrahmens senkrecht zur Wicklungsebene der Erregerwicklung der Drosselspule liegt, vermeidet man außerdem die Ausbildung von Windungsspannungen innerhalb des Blechpaketrahmens, so daß die vorteilhafte Formgebung keine wesentlichen zusätzlichen elektrischen Verluste zur Folge hat. Weiterhin ist durch die Aufteilung des Blechpaketrahmens in mehrere nebeneinander liegende Wicklungen das Auftreten von Wirbelströmen in Grenzen gehalten.Because the winding plane of the laminated core frame is perpendicular to the winding plane the excitation winding of the choke coil, one also avoids the training of winding tensions within the laminated core frame, so that the advantageous Shaping does not result in any significant additional electrical losses. Furthermore, by dividing the laminated core frame into several side by side horizontal windings, the occurrence of eddy currents is kept within limits.

Es empfiehlt sich, die Wicklungen des Blechpaketrahmens aus flachkant gewickelten Bändern aus Dynamoblech herzustellen, wobei diese gleich auf den Isolierkörper aufgewickelt werden.It is recommended that the windings of the laminated core frame be made flat Manufacture wound strips from dynamo sheet, with these equal to the insulating body be wound up.

Statt Blechbänder kann aber ebenfalls Draht verwendet werden.Instead of sheet metal strips, wire can also be used.

Man erhält außerdem auf einfachste Weise durch eine Dickenabstufung der nebeneinander angeordneten Wicklungen eine optimale Anpassung des Blechpaketrahmens an die Flußverteilung. Dadurch kann für den Blechpaketrahmen insgesamt an Gewicht gespart werden.It is also obtained in the simplest possible way by grading the thickness The windings arranged next to one another enable the laminated core frame to be optimally adapted to the flow distribution. This can mean overall weight for the laminated core frame be saved.

Im folgenden sei die Erfindung anhand des in den Fig. 1 und 2 dargestellten Ausführungsbeispiels noch näher erläutert. Fig. 1 zeigt einen Querschnitt durch eine gemäß der Erfindung ausgebildete Glättungsdrosselspule, in Fig. 2 ist der Schnitt entlang der Linie II-II in Fig. 1 dargestellt.In the following the invention with reference to that shown in FIGS. 1 and 2 is shown Embodiment explained in more detail. Fig. 1 shows a cross section through a smoothing choke coil designed according to the invention, in Fig. 2 is the section shown along the line II-II in FIG.

Bei der Glättungsirossel 1 ist die aus Einzelscheiben aufgebaute Erregerwicklung 2 im rechteckförmigen Innenraum 3 eines Isolierkörpers 4 angeordnet. Der Isolierkörper 4 dient somit als tuftführungskanal für die Erregerwicklung 2 und außerdem als Tragkörper für den die Erregerwicklung 2 umgebenden, als magnetischem Rückschluß ausgeführten Blechpaketrahmen 5. Dieser besteht aus mehreren, auf dem Isolierkörper 4 nebenein ander liegend angeordneten Wicklungen -6, 7, 8, 9, 10, 11, die in Abstand voneinander liegen, so daß zwischen ihnen Bue'tkanäle 12 zur besseren Kühlung verbleiben. Da die Wicklungen 7 bis 11 unmittelbar auf den Isolierkörper 4 aufgewickelt werden, entfallen sämtliche zusätzlichen Befestigungamittel.In the smoothing iron 1 is the excitation winding made up of individual disks 2 arranged in the rectangular interior 3 of an insulating body 4. The insulator 4 thus serves as a tuft guide channel for the excitation winding 2 and also as a support body for the field winding 2 surrounding it, as a magnetic one Conclusion executed laminated core frame 5. This consists of several, on the Insulating body 4 side by side arranged windings -6, 7, 8, 9, 10, 11, which are at a distance from each other, so that between them Bue'tkanäle 12 to better cooling remain. Since the windings 7 to 11 directly on the insulating body 4 are wound up, all additional fasteners are omitted.

Außerdem sind die Wicklungen symmetrisch zur Mitte in ihren Dicken der Flußverteilung angepaßt. Dies bedeutet, daß die einzelnen aus flachkant gewickelten Bändern aus Dynamoblech bestehenden Wicklungen jeweils unterschiedliche Windungszahlen aufweisen. Die Windungszahlen der in der Mitte liegenden Wicklungen 8 und 9 sind am größten, die der an den äußeren Seiten liegenden Wicklungen 6 und 11 am kleinsten. Man erzielt somit eine optimale Größenanpassung des Blechpaketrahmens 5 an den magnetischen Fluß, so daß insgesamt bei geringstem Gewicht des Blechpaketrahmens 5 der notwendige Energieinhalt der Drosselspule 1 erzielbar ist.In addition, the windings are symmetrical about the center in their thicknesses adapted to the flow distribution. This means that the individual is wound from flat edge Bands made of dynamo sheet windings each have different numbers of turns exhibit. The turns of the windings in the middle are 8 and 9 the largest, those of the windings 6 and 11 lying on the outer sides the smallest. An optimal size adaptation of the laminated core frame 5 to the magnetic one is thus achieved Flow, so that overall with the lowest weight of the laminated core frame 5 the necessary Energy content of the choke coil 1 can be achieved.
