Description

Verfahren zum Herstellen einer Wicklungsanordnung einer Spule Method for producing a winding arrangement of a coil
Die Erfindung betrifft ein Verfahren zum Herstellen einer Wicklungsanordnung einer Spule, sowie einen elektrischen Leiter hierzu uno eine nach dem Verfahren hergestellte WieklungsanOrdnung.The invention relates to a method for producing a winding arrangement of a coil, and an electrical conductor for this purpose and a weighing arrangement produced according to the method.
Zum Herstellen einer Spule, z.B. eine Spule für einen Trans¬ formator, ist es bekannt, einen elektrischen Leiter auf einen Spulenkörper aufzuwickeln. Bei verschεlteten Wicklungsanord¬ nungen müssen dabei einzelne Teilwicklungen nacheinander ge¬ wickelt werden, welche dann nachträglich miteinander verschal¬ tet werden. Ein spezieller Fall dabei ist die sogenannte Sturz¬ wicklung. Das Herstellen einer Spule mit einer derartigen Wicklung ist recht aufwendig.For making a coil, e.g. a coil for a transformer, it is known to wind an electrical conductor on a coil former. In the case of interconnected winding arrangements, individual partial windings must be wound one after the other, which are then subsequently interconnected with one another. A special case is the so-called lintel winding. The production of a coil with such a winding is quite complex.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzu¬ geben, durch das die Herstellung einer Spule vereinfacht werden kann. Eine weitere Aufgabe ist es, einen elektrischen Leiter für ein derartiges Verfahren bereitzustellen sowie eine nach dem Verfahren hergestelle Wicklungsanordnung anzugeben.The invention is based on the object of specifying a method by which the manufacture of a coil can be simplified. Another object is to provide an electrical conductor for such a method and to specify a winding arrangement produced using the method.
-Die Lösung der Aufgabe gelingt mit einem Verfahren gemäß den Merkmalen des Anspruchs 1. Auf diese Weise wird eine wesent- liehe Zeitersparnis bei der Herstellung der Spule erzielt. Das Wickeln der Spule kann dabei wesentlich schneller als bisher erfolgen. Dies gilt insbesondere dann, wenn ein Leiter verwendet wird, bei dem bereits zusätzliche Maßnahmen ausge¬ führt sind, die bisher während des Wickelvorganges durchge- führt wurden. Dies betrifft z.B. das Einlegen von Zwischen¬ lagen für eine Isolation zwischen Wicklungen oder einen Kantenschutz. Das Verfahren eignet sich auch für aufwendig verschachtelte Wicklungen.The problem is solved with a method according to the features of claim 1. In this way, considerable time is saved in the manufacture of the coil. The winding of the coil can be done much faster than before. This applies in particular when a conductor is used, in which additional measures have already been carried out, which were previously carried out during the winding process. This affects e.g. inserting intermediate layers for insulation between windings or edge protection. The process is also suitable for complex nested windings.
Es ist günstig, wenn zumindest ein Teil des Leiters unter Bildung einer Scheibenwicklung auf den Wickelkörper aufge- wickelt wird. Hier sind besonders hohe Einsparungen in der Fertigung möglich, da während des .Wickelvorganges zumindest zwei Scheibenspulen entstehen. Überlappen in einem Abschnitt des Leiters mehr als 2 Leiterstücke einander, so können mit einer Wickeldrehung gleichzeitig mehrere Windungen erzeugt werden.It is advantageous if at least part of the conductor is formed on the winding body to form a disk winding. is wrapped. Particularly high savings in production are possible here, since at least two disc coils are formed during the winding process. If more than 2 conductor pieces overlap in a section of the conductor, several turns can be generated simultaneously with one winding turn.
Vorteilhafterweise kann sich ein Sturzwickelschritt anschlie¬ ßen. Dabei ist es günstig, wenn in einem weiteren Schritt die Enden einander überlappender Leiterstücke elektrisch mit¬ einander verbunden werden. Auf diese Weise entfällt ein nach¬ trägliches Ablängen der Leiter, wodurch auch eine Verletzungs¬ gefahr für die bereits fertige Wicklung verringert ist. Es entstehen saubere Verbindungsstellen an der Spule.Advantageously, a lintel winding step can follow. It is advantageous if in a further step the ends of overlapping conductor pieces are electrically connected to one another. In this way there is no need to subsequently cut the conductors to length, which also reduces the risk of injury for the winding that is already finished. There are clean connection points on the coil.
Die Lösung der weiteren Aufgabe gelingt mit einem elektri¬ schen Leiter gemäß Anspruch 5. Auf diese Weise ist eine Art vorkonfektionierter Leiter gegeben, der sich besonders einfach und schnell verarbeiten läßt. Je nach Anzahl von parallelen Leiterstücken kann so die Wickelzeit für eine Spule ver¬ ringert werden.The further task is solved with an electrical conductor according to claim 5. In this way a type of pre-assembled conductor is provided which can be processed particularly simply and quickly. Depending on the number of parallel conductor pieces, the winding time for a coil can be reduced.
Die jeweiligen Leiterstücke können dabei mehrere parallel geschaltete Leiteradern umfassen, wobei die Leiterstücke auch als Drilleiter ausgebildet sein können. Dadurch eignet sich der Leiter auch für Anwendungen im Energiebereich, z.B. für Hochspannungstransformatoren.The respective conductor pieces can comprise a plurality of conductor wires connected in parallel, wherein the conductor pieces can also be designed as twisted pairs. This means that the conductor is also suitable for applications in the energy sector, e.g. for high voltage transformers.
Es ist vorteilhaft, wenn jeweils zwei einander überlappende Enden zweier Leiterstücke elektrisch miteinander verbindbar ausgebildet sind. Auf diese Weise gestaltet sich das nach¬ trägliche Verschalten des Leiters bei fertiggestellter Spule besonders einfach. Ein nachträgliches Anpassen oder Ablängen des Leiters erübrigt sich oder wird zumindest vereinfacht. Die Verbindungsstellen sind also genau vorgegeben. Mit Vorteil können die Leiterstücke durch Distanzeinlagen .voneinander ge¬ trennt -sein. Dadurch entfällt beim Wickeln des Transformators das aufwendige Zwischenwickeln von Distanzeinlagen oder Kanten¬ schutzringen wie es bisher üblich war. Dies gilt insbesondere für den Innenbereich einer Spule.It is advantageous if two mutually overlapping ends of two conductor pieces are each electrically connectable. In this way, subsequent connection of the conductor when the coil is finished is particularly simple. Subsequent adjustment or cutting to length of the conductor is unnecessary or is at least simplified. The connection points are therefore precisely specified. With advantage the conductor pieces can be separated from one another by spacer inserts. As a result, the time-consuming intermediate winding of spacer inserts or edge protection rings, as was previously the case, is eliminated when the transformer is being wound. This applies in particular to the inside of a coil.
Die Lösung der dritten Aufgabe gelingt mit einer Wicklungsan¬ ordnung gemäß Anspruch 10. Eine derartige Wicklungsanordnung zeichnet sich durch ihre geringen Baumaße aus, da die Spule wesentlich kompakter gewickelt werden kann als bisher. Darüber hinaus ist sie einfacher und schneller herzustellen. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den übrigen Unteraπsprüchen angegeben.The third task is solved with a winding arrangement according to claim 10. Such a winding arrangement is characterized by its small dimensions, since the coil can be wound much more compactly than before. It is also easier and faster to manufacture. Further advantageous embodiments of the invention are specified in the remaining sub-claims.
Die Erfindung und weitere Vorteile werden nachfolgend anhand der Zeichnung beispielhaft näher erläutert. Es zeigen:The invention and further advantages are explained in more detail below by way of example with reference to the drawing. Show it:
FIG 1 einen Leiter,1 shows a conductor,
FIG 2 den Leiter im Querschnitt entlang der Linie II-II , FIG 3 einen weiteren Leiter im Querschnitt entlang der Linie III-III, und FIG 4 eine Teilaußenansicht einer Wicklungsanordnung.2 shows the conductor in cross section along the line II-II, FIG. 3 shows another conductor in cross section along the line III-III, and FIG. 4 shows a partial external view of a winding arrangement.
In FIG 1 ist ein elektrischer Leiter 1 für eine Wickluπgsan- Ordnung gezeigt, der aus einer Mehrzahl von Leiterstücken 3a bis 3e besteht. Die Leiterstücke 3a bis 3e sind einander wenigstens teilweise überlappend aber gegeneinander isoliert miteinander verbunden, so daß eine Art vorkonfektionierter Leiter gegeben ist. Die Längen der Leiterstücke 3a bis 3e sind derart vorgegeben, daß beim Wicklen einer Spule Leiterabschnit¬ te A bis D jeweils vorgegebenen Windungen zugeordnet sind. Da¬ bei sind die freien Enden der Leiterstücke 3a bis 3e gegebenen¬ falls derart bemessen, daß diese nach dem Wickeln miteinander elektrisch verbunden werden können. In der vorliegenden FIG 1 sei dies beispielhaft anhand der freien Enden 5c und 5d der Leiterstücke 3c, 3d aufgezeigt. Sind diese miteinander ver¬ bunden, so ist der Leiter 1 entlang den Leiterabschnitten B, und D elektrisch leitend. Mit den Bezugszeichen 6a, 6b, 6c si die Übergänge zwischen den Leiterabschnitten A bis D bezeich- net. Die freien Enden 5a, 5b der endseitigen Leiterstücke 3a, 3e bilden die Anschlüsse für den externen Anschluß der später Wicklungsanordnung. In einem Abschnitt können auch mehr als zwei Leiterstücke parallel angeordnet sein.1 shows an electrical conductor 1 for a winding arrangement, which consists of a plurality of conductor pieces 3a to 3e. The conductor pieces 3a to 3e are connected to one another at least partially overlapping but isolated from one another, so that a type of pre-assembled conductor is provided. The lengths of the conductor pieces 3a to 3e are predefined in such a way that, when a coil is being wound, conductor sections A to D are each assigned predetermined windings. The free ends of the conductor pieces 3a to 3e are dimensioned such that they can be electrically connected to one another after winding. In the present FIG. 1, this is exemplified by the free ends 5c and 5d of the Conductor pieces 3c, 3d shown. If these are connected to one another, the conductor 1 is electrically conductive along the conductor sections B and D. The transitions between the conductor sections A to D are designated by the reference symbols 6a, 6b, 6c. The free ends 5a, 5b of the end-side conductor pieces 3a, 3e form the connections for the external connection of the later winding arrangement. In a section, more than two conductor pieces can also be arranged in parallel.
Der in FIG 2 gezeigte Querschnitt des Leiters 1 aus FIG 1 ent¬ lang der Linie II-II stellt eine einfache Ausführungsvariante dar. Der mit la bezeichnete Leiter weist zwei Leiterstücke 3c, 3d auf, die gegeneinander durch die Zwischenlage 9b isoliert sind. Die Leiterstücke 3c, 3d sind von einer gemeinsamen Iso- lierung 7b umgeben. Die Leiterstücke 3c, 3d können dabei eine oder mehrere Leiteradern, beispielsweise als ■Volleiter oder Drilleiter, umfassen. Diese Ausführung ist besonders platz¬ sparend, da sich daraus eine sehr eng und kompakt gewickelte Spule herstellen läßt, die sehr kleine Baumaße aufweist.The cross section shown in FIG. 2 of the conductor 1 from FIG. 1 along the line II-II represents a simple embodiment variant. The conductor labeled la has two conductor pieces 3c, 3d which are insulated from one another by the intermediate layer 9b. The conductor pieces 3c, 3d are surrounded by a common insulation 7b. The conductor pieces 3c, 3d can comprise one or more conductor wires, for example as a solid conductor or a stranded conductor. This embodiment is particularly space-saving since it can be used to produce a very tightly and compactly wound coil which has very small dimensions.
Der in FIG 3 gezeigte Querschnitt zeigt eine bevorzugte Vari¬ ante des Leiters 1 aus FIG 1. Der mit lb bezeichnete Leiter weist zwei jeweils von einer separaten Isolierung 11a, 11b um¬ gebenen Leiterstücke 3c und 3d auf. Diese sind, wie in der Zeichnung angedeutet, als verketteter Zwillingsdrilleiter ausgebildet. Zwischen ihnen ist eine kapazitätsbestimmende Zwischeneinlage 9b angeordnet. Die Leiterstücke 3c, 3d sind von der gemeinsamen Isolierung 7b umgeben. Diese kann bei der vorliegenden Ausführung ggf. dünner als bei der Ausführung ge- maß FIG 1 ausgeführt sein.. Eine Funktion der gemeinsamen Iso¬ lierung 7b ist es, die jeweiligen Leiterstücke zusammenzuhal¬ ten oder miteinander zu verbinden. Wesentlich ist dabei, daß aufgrund der gemeinsamen Isolierung 7a bis 7d auf die beim bis herigen Stand der Technik aus elektrischen Gründen (Stoßspan- nungspegel) verwendeten Kantenschutzringe verzichtet werden kann. In FIG 4 ist eine Teilaußenansicht einer Wicklungsanordnung 12 gezeigt, bei. der der Leiter 1 gemäß FIG 1 verwendet ist. Die Wicklungsanordnung 12 ist dabei als Spule mit Sturzwick¬ lung ausgebildet. Die Leiterabschnitte A, B, C und D bilden dabei jeweils Scheibenspulenpaare 13a, 14a bis 13d, 14d. Die freien Enden 5a, 5b der endseitigen Scheibenspulen 13a bzw. 14d bilden die Anschlüsse für die Wicklungsanordnung 12. Die ein¬ zelnen Scheibenspulen 13a bis 14d sind durch Distanzeinlagen 15 voneinander getrennt.The cross section shown in FIG. 3 shows a preferred variant of the conductor 1 from FIG. 1. The conductor labeled 1b has two conductor pieces 3c and 3d, each surrounded by separate insulation 11a, 11b. As indicated in the drawing, these are designed as a concatenated twin wire. A capacity-determining intermediate insert 9b is arranged between them. The conductor pieces 3c, 3d are surrounded by the common insulation 7b. In the present embodiment, this can possibly be made thinner than in the embodiment according to FIG. 1. One function of the common insulation 7b is to hold the respective conductor pieces together or to connect them to one another. It is essential here that, due to the common insulation 7a to 7d, the edge protection rings used in the prior art for electrical reasons (surge voltage level) can be dispensed with. 4 shows a partial exterior view of a winding arrangement 12, at. the conductor 1 according to FIG 1 is used. The winding arrangement 12 is designed as a coil with a drop winding. The conductor sections A, B, C and D each form disk coil pairs 13a, 14a to 13d, 14d. The free ends 5a, 5b of the end-side disc coils 13a and 14d form the connections for the winding arrangement 12. The individual disc coils 13a to 14d are separated from one another by spacer inserts 15.
Bei der gezeigten Teilaußenansicht ist nun der Bereich der Wicklungsanordnung 12 gezeigt, an der die Verbindungen zwi¬ schen den Leiterstücken 3a bis 3e hergestellt sind. Dabei¬ bilden beispielhaft für die gesamte Wicklungsanordnuπg 12 die freien Enden 5c, 5d der Leiterstücke 3c und 3d eine Ver¬ bindung zwischen den beiden Scheibenspulen 13c und 14c des Leiterabschnittes C. Die Übergänge 6a bis 6c, die jeweils von den Leiterstücken 3b bis 3d gebildet sind, kommen dabei zwi¬ schen den jeweiligen Scheibenspulen zweier benachbarter Lei- terabschnitte, beispielsweise Übergang 6c zwischen den Lei¬ terabschnitten D und C mit den Scheibenspulen 13d und 14c, zu liegen. Eine weitere Verbindungsstelle zwischen den jeweils nebeneinander geordneten Scheibenspulen liegt dabei (nicht näher dargestellt), wie bei Sturzwicklungen üblich, an der Innenseite der Wicklungsanordnung 12. Eine derartige Übergangs¬ stelle entspricht in FIG 1 den jeweiligen Mitten der Leiterab¬ schnitte A bis D.In the partial exterior view shown, the area of the winding arrangement 12 is now shown on which the connections between the conductor pieces 3a to 3e are made. For example, for the entire winding arrangement 12, the free ends 5c, 5d of the conductor pieces 3c and 3d form a connection between the two disk coils 13c and 14c of the conductor section C. The transitions 6a to 6c, each formed by the conductor pieces 3b to 3d are located between the respective disk coils of two adjacent conductor sections, for example transition 6c between the conductor sections D and C with the disk coils 13d and 14c. A further connection point between the disc coils arranged next to one another is (not shown in more detail), as is customary in the case of drop windings, on the inside of the winding arrangement 12. Such a transition point corresponds in FIG. 1 to the respective centers of the conductor sections A to D.
Wird ein Leiter gemäß FIG 1 auf einem Wickelkörper beispiel- haft zu einer Wicklungsanordnung 12 gemäß FIG 4 verarbeitet, so können wesentliche Vorteile in der Fertigung erzielt wer¬ den. Trotz des erhöhten Aufwandes bei der Herstellung des Leiters 1 werden bei der gesamten Wicklungsanordnung 12 Ein¬ sparungen erreicht. Dies betrifft insbesondere die Anwendung bei Scheibenspulen und bei Sturzwicklungen. Trotz großer Be- denken in Fachkreisen in bezug auf die Handhabbarkeit hat es sich gezeigt, daß die Verwendung des vorgeschlagenen vorkon¬ fektionierten Leiters 1 insbesondere bei großen Wicklungsan¬ ordnungen, z.B. für Hochspannungstransformatoren, besonders günstig ist. Aus Versuchen mit dem aufgezeigten Verfahren habe sich zusätzlich noch folgende Vorteile gezeigt:If a conductor according to FIG. 1 is processed on a winding body, for example to form a winding arrangement 12 according to FIG. 4, then significant advantages in production can be achieved. Despite the increased effort in the manufacture of the conductor 1, savings are achieved in the entire winding arrangement 12. This applies in particular to the use with disc coils and with drop windings. Despite large loads think in specialist circles with regard to the handling, it has been shown that the use of the proposed pre-assembled conductor 1 is particularly favorable, particularly in the case of large winding arrangements, for example for high-voltage transformers. Experiments with the method shown have also shown the following advantages:
- Schutzwinkel an der Innenseite von Wicklungsanordnungen bzw. von Spulen für Transformatoren können ersatzlos entfallen. - Es können bis zu vier normale Doppelspulen aus Zwillings- Drilleiter gewickelt werden.- Protective angles on the inside of winding arrangements or coils for transformers can be omitted without replacement. - Up to four normal double coils can be wound from twin wire.
- Die miteinander elektrisch zu verbindenden freien Enden 5c 5d liegen nach dem Wickeln der Spule immer in richtiger Po¬ sition. - Kapazitätsbestimmende Einlagen können bereits im vorkon¬ fektionierten Leiter enthalten sein. Es entfällt das Stanzen und Einbringen von Radialbeilagen beim Wickeln einer Wick¬ lungsanordnung.The free ends 5c 5d to be electrically connected to one another are always in the correct position after winding the coil. - Deposits that determine capacity can already be contained in the pre-assembled conductor. There is no need to punch and insert radial inserts when winding a winding arrangement.
- Bei Bedarf können auch nur eine Eingangsgruppe einer Wick- lungsanordnung oder wenige Gruppen vorgefertigt werden.- If required, only one input group of a winding arrangement or a few groups can be prefabricated.
- Durch den Entfall von Schutzwinkeln stellt sich eine niedri¬ gere hσt-spot Temperatur in der Wicklungsanordnung ein.The elimination of protective angles results in a lower hσt-spot temperature in the winding arrangement.
Bei der Anwendung im Hochspannungsbereich werden die Zwi- schenlagen 9a bis 9d bevorzugt in Stärken zwischen 0,1 bis 2 mm, insbesondere 0,3 bis 1 mm verwendet. Dabei sind Span¬ nungsbeanspruchungen zwischen 50 bis 150 KV berücksichtigt. When used in the high-voltage range, the intermediate layers 9a to 9d are preferably used in thicknesses between 0.1 to 2 mm, in particular 0.3 to 1 mm. Voltage stresses between 50 and 150 KV are taken into account.
