Definitions
- the invention relates to a method for producing a winding arrangement of a coil, as well as an electrical conductor arrangement therefor and a winding arrangement produced by the method.
- a coil for example a coil for a transformer
- individual partial windings must be wound one after the other, which are then interconnected subsequently.
- a special case is the so-called lintel winding.
- the production of a coil with such a winding is quite complex.
- DE-A1-32 14 171 shows such a winding arrangement.
- the conductor used there consists of partial conductors that are connected in parallel and in series. There is no further information on the manufacture of the winding.
- the invention has for its object to provide a method by which the manufacture of a coil can be simplified. Another object is to provide an electrical conductor arrangement for such a method and to specify a winding arrangement produced using the method.
- the problem is solved with a method according to the features of claim 1.
- a substantial time saving is achieved in the manufacture of the coil.
- the winding of the coil can be done much faster than before. This applies in particular if a conductor, in particular a conductor arrangement, is used for which additional measures have already been carried out which were previously carried out during the winding process. This applies, for example, to the insertion of intermediate layers for insulation between windings or edge protection.
- the process is also suitable for complex nested windings.
- At least part of the conductor arrangement is wound onto the winding body to form a disk winding. Particularly high savings in production are possible here, since at least two disc coils are created during the winding process. If more than two conductor pieces overlap one another in a section of the conductor arrangement, several turns can be generated simultaneously with one winding rotation.
- a lintel winding step can advantageously follow. It is advantageous if the ends of mutually overlapping conductor pieces are electrically connected to one another in a further step. In this way, the conductors are not cut to length later, which also reduces the risk of injury to the already finished winding. There are clean connection points on the coil.
- 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.
- the conductor arrangement is also suitable for applications in the energy sector, for example for high-voltage transformers.
- connection points are therefore precisely specified.
- the conductor pieces can advantageously be separated from one another by spacer inserts. This eliminates the time-consuming intermediate winding of spacer inserts or edge protection rings when winding the transformer, as was previously the case. This applies in particular to the inside of a coil.
- conductor 1 shows an electrical conductor arrangement, hereinafter referred to as conductor 1, for a winding arrangement, which consists of a plurality of conductor pieces 3a to 3e.
- the conductor pieces 3a to 3e are at least partially overlapping one another, but are connected to one another in an insulated manner, so that a type of prefabricated conductor is provided.
- the lengths of the conductor pieces 3a to 3e are specified 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 optionally dimensioned such that they can be electrically connected to one another after winding. In the present FIG.
- 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 9c.
- the conductor pieces 3c, 3d are surrounded by a common insulation 7c.
- the conductor pieces 3c, 3d can comprise one or more conductor wires, for example as a solid conductor or a stranded conductor. This version is particularly space-saving, since it can be used to produce a very tightly and compactly wound coil which has very small dimensions.
- 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. An intermediate layer 9c is arranged between them and is designed to determine capacity.
- the conductor pieces 3c, 3d are surrounded by the common insulation 7c. In the present embodiment, this can optionally be made thinner than in the embodiment according to FIG. 1.
- a function of the common insulation 7c is to hold the respective conductor pieces together or to connect them to one another. It is essential that Because of the common insulation 7a to 7d (FIG. 1), the edge protection rings used in the prior art for electrical reasons (surge voltage level) can be dispensed with.
- FIG. 4 shows a partial external view of a winding arrangement 12 in which 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.
- the area of the winding arrangement 12 is now shown on which the connections between the conductor pieces 3a to 3e are made.
- 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 which are each formed by the conductor pieces 3b to 3d, come thereby to lie 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, which are 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.
- 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.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen einer Wicklungsanordnung einer Spule, sowie eine elektrische Leiteranordnung hierzu und eine nach dem Verfahren hergestellte Wicklungsanordnung.The invention relates to a method for producing a winding arrangement of a coil, as well as an electrical conductor arrangement therefor and a winding arrangement produced by the method.
Zum Herstellen einer Spule, zum Beispiel eine Spule für einen Transformator, ist es bekannt, einen elektrischen Leiter auf einen Spulenkörper aufzuwickeln. Bei verschalteten Wicklungsanordnungen müssen dabei einzelne Teilwicklungen nacheinander gewickelt werden, welche dann nachtraglich miteinander verschaltet werden. Ein spezieller Fall dabei ist die sogenannte Sturzwicklung. Das Herstellen einer Spule mit einer derartigen Wicklung ist recht aufwendig.To manufacture a coil, for example 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 interconnected subsequently. A special case is the so-called lintel winding. The production of a coil with such a winding is quite complex.
Die DE-A1-32 14 171 zeigt eine derartige Wicklungsanordnung. Der dort verwendete Leiter besteht aus Teilleitern, die parallel und in Reihe geschaltet sind. Nähere Hinweise auf die Herstellung der Wicklung sind nicht gegeben.DE-A1-32 14 171 shows such a winding arrangement. The conductor used there consists of partial conductors that are connected in parallel and in series. There is no further information on the manufacture of the winding.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, durch das die Herstellung einer Spule vereinfacht werden kann. Eine weitere Aufgabe ist es, eine elektrische Leiteranordnung für ein derartiges Verfahren bereitzustellen sowie eine nach dem Verfahren hergestellte Wicklungsanordnung anzugeben.The invention has for its object to provide a method by which the manufacture of a coil can be simplified. Another object is to provide an electrical conductor arrangement 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 wesentliche 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, insbesondere eine Leiteranordnung, verwendet wird, bei dem bereits zusätzliche Maßnahmen ausgeführt sind, die bisher während des Wickelvorgangs durchgeführt wurden. Dies betrifft zum Beispiel das Einlegen von Zwischenlagen 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, a substantial time saving is achieved in the manufacture of the coil. The winding of the coil can be done much faster than before. This applies in particular if a conductor, in particular a conductor arrangement, is used for which additional measures have already been carried out which were previously carried out during the winding process. This applies, for example, to the insertion of 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 der Leiteranordnung unter Bildung einer Scheibenwicklung auf den Wickelkörper aufgewickelt wird. Hier sind besonders hohe Einsparungen in der Fertigung möglich, da während des Wickelvorgangs zumindest zwei Scheibenspulen entstehen. Überlappen in einem Abschnitt der Leiteranordnung mehr als zwei Leiterstücke einander, so können mit einer Wickeldrehung gleichzeitig mehrere Windungen erzeugt werden.It is advantageous if at least part of the conductor arrangement is wound onto the winding body to form a disk winding. Particularly high savings in production are possible here, since at least two disc coils are created during the winding process. If more than two conductor pieces overlap one another in a section of the conductor arrangement, several turns can be generated simultaneously with one winding rotation.
Vorteilhafterweise kann sich ein Sturzwickelschritt anschließen. Dabei ist es günstig, wenn in einem weiteren Schritt die Enden einander überlappender Leiterstücke elektrisch miteinander verbunden werden. Auf diese Weise entfällt ein nachträgliches Ablängen der Leiter, wodurch auch eine Verletzungsgefahr für die bereits fertige Wicklung verringert ist. Es entstehen saubere Verbindungsstellen an der Spule.A lintel winding step can advantageously follow. It is advantageous if the ends of mutually overlapping conductor pieces are electrically connected to one another in a further step. In this way, the conductors are not cut to length later, which also reduces the risk of injury to the already finished winding. There are clean connection points on the coil.
Die Lösung der weiteren Aufgabe gelingt mit einer elektrischen Leiteranordnung 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 verringert werden.The solution of the further problem is achieved with an electrical conductor arrangement according to claim 5. In this way, a type of pre-assembled conductor is provided which can be processed particularly easily 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 die Leiteranordnung auch für Anwendungen im Energiebereich, zum Beispiel 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. As a result, the conductor arrangement is also suitable for applications in the energy sector, for example 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 nachträgliche Verschalten der Leiteranordnung bei fertiggestellter Spule besonders einfach. Ein nachträgliches Anpassen oder Ablängen des Leiters oder der Leiteranordnung erübrigt sich oder wird zumindest vereinfacht. Die Verbindungsstellen sind also genau vorgegeben. Mit Vorteil können die Leiterstücke durch Distanzeinlagen voneinander getrennt sein. Dadurch entfällt beim Wickeln des Transformators das aufwendige Zwischenwickeln von Distanzeinlagen oder Kantenschutzringen, 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, the subsequent connection of the conductor arrangement is particularly simple when the coil is finished. Subsequent adaptation or cutting to length of the conductor or the conductor arrangement is unnecessary or is at least simplified. The connection points are therefore precisely specified. The conductor pieces can advantageously be separated from one another by spacer inserts. This eliminates the time-consuming intermediate winding of spacer inserts or edge protection rings when winding the transformer, as was previously the case. This applies in particular to the inside of a coil.
Die Lösung der dritten Aufgabe gelingt mit einer Wicklungsanordnung gemäß Anspruch 9. 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 Unteransprüchen angegeben.The solution to the third task is achieved with a winding arrangement according to claim 9. 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 subclaims.
Die Erfindung und weitere Vorteile werden nachfolgend anhand der Zeichnung beispielhaft näher erläutert. Es zeigen:
- Figur 1 einer Leiteranordnung,
- Figur 2 die Leiteranordnung im Querschnitt entlang der Linie II-II,
- Figur 3 eine weitere Leiteranordnung im Querschnitt entlang der Linie III-III, und
- Figur 4 eine Teilaußenansicht einer Wicklungsanordnung.
- 1 shows a conductor arrangement,
- FIG. 2 shows the conductor arrangement in cross section along the line II-II,
- Figure 3 shows a further conductor arrangement in cross section along the line III-III, and
- Figure 4 is a partial exterior view of a winding arrangement.
In Figur 1 ist eine elektrische Leiteranordnung, nachfolgend als Leiter 1 bezeichnet, für eine Wicklungsanordnung gezeigt, die 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 Wickeln einer Spule Leiterabschnitte A bis D jeweils vorgegebenen Windungen zugeordnet sind. Dabei sind die freien Enden der Leiterstücke 3a bis 3e gegebenenfalls derart bemessen, daß diese nach dem Wickeln miteinander elektrisch verbunden werden können. In der vorliegenden Figur 1 sei dies beispielhaft anhand der freien Enden 5c und 5d der Leiterstücke 3c, 3d aufgezeigt. Sind diese miteinander verbunden, so ist der Leiter 1 entlang den Leiterabschnitten B, C und D elektrisch leitend. Mit den Bezugszeichen 6a, 6b, 6c sind die Übergänge zwischen den Leiterabschnitten A bis D bezeichnet. Die freien Enden 5a, 5b der endseitigen Leiterstücke 3a, 3e bilden die Anschlüsse für den externen Anschluß der späteren Wicklungsanordnung. In einem Abschnitt können auch mehr als zwei Leiterstücke parallel angeordnet sein.1 shows an electrical conductor arrangement, hereinafter referred to as conductor 1, for a winding arrangement, which consists of a plurality of conductor pieces 3a to 3e. The conductor pieces 3a to 3e are at least partially overlapping one another, but are connected to one another in an insulated manner, so that a type of prefabricated conductor is provided. The lengths of the conductor pieces 3a to 3e are specified 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 optionally dimensioned such that they can be electrically connected to one another after winding. In the present FIG. 1, this is exemplified by the
Der in FIG 2 gezeigte Querschnitt des Leiters 1 aus FIG 1 entlang 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 9c isoliert sind. Die Leiterstücke 3c, 3d sind von einer gemeinsamen Isolierung 7c umgeben. Die Leiterstücke 3c, 3d können dabei eine oder mehrere Leiteradern, beispielsweise als Volleiter oder Drilleiter, umfassen. Diese Ausführung ist besonders platzsparend, 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
Der in FIG 3 gezeigte Querschnitt zeigt eine bevorzugte Variante des Leiters 1 aus FIG 1. Der mit lb bezeichnete Leiter weist zwei jeweils von einer separaten Isolierung lla, llb umgebenen Leiterstücke 3c und 3d auf. Diese sind, wie in der Zeichnung angedeutet, als verketteter Zwillingsdrilleiter ausgebildet. Zwischen ihnen ist eine Zwischenlage 9c angeordnet, die kapazitätsbestimmend ausgebildet ist. Die Leiterstücke 3c, 3d sind von der gemeinsamen Isolierung 7c umgeben. Diese kann bei der vorliegenden Ausführung ggf. dünner als bei der Ausführung gemäß FIG 1 ausgeführt sein. Eine Funktion der gemeinsamen Isolierung 7c ist es, die jeweiligen Leiterstücke zusammenzuhalten oder miteinander zu verbinden. Wesentlich ist dabei, daß aufgrund der gemeinsamen Isolierung 7a bis 7d (FIG 1) auf die beim bisherigen Stand der Technik aus elektrischen Gründen (Stoßspannungspegel) verwendeten Kantenschutzringe verzichtet werden kann.The cross section shown in FIG. 3 shows a preferred variant of the conductor 1 from FIG. 1. The conductor labeled 1b has two
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 Sturzwicklung 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 einzelnen Scheibenspulen 13a bis 14d sind durch Distanzeinlagen 15 voneinander getrennt.FIG. 4 shows a partial external view of a winding arrangement 12 in which 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
Bei der gezeigten Teilaußenansicht ist nun der Bereich der Wicklungsanordnung 12 gezeigt, an der die Verbindungen zwischen den Leiterstücken 3a bis 3e hergestellt sind. Dabei bilden beispielhaft für die gesamte Wicklungsanordnung 12 die freien Enden 5c, 5d der Leiterstücke 3c und 3d eine Verbindung 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 zwischen den jeweiligen Scheibenspulen zweier benachbarter Leiterabschnitte, beispielsweise Übergang 6c zwischen den Leiterabschnitten 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 Übergangsstelle entspricht in FIG 1 den jeweiligen Mitten der Leiterabschnitte 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
Wird ein Leiter gemäß FIG 1 auf einem Wickelkörper beispielhaft zu einer Wicklungsanordnung 12 gemäß FIG 4 verarbeitet, so können wesentliche Vorteile in der Fertigung erzielt werden. Trotz des erhöhten Aufwandes bei der Herstellung des Leiters 1 werden bei der gesamten Wicklungsanordnung 12 Einsparungen erreicht. Dies betrifft insbesondere die Anwendung bei Scheibenspulen und bei Sturzwicklungen. Trotz großer Bedenken in Fachkreisen in bezug auf die Handhabbarkeit hat es sich gezeigt, daß die Verwendung des vorgeschlagenen vorkonfektionierten Leiters 1 insbesondere bei großen Wicklungsanordnungen, z.B. für Hochspannungstransformatoren, besonders günstig ist. Aus Versuchen mit dem aufgezeigten Verfahren haben sich zusätzlich noch folgende Vorteile gezeigt:
- 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.
- Die miteinander elektrisch zu verbindenden freien
5d liegen nach dem Wickeln der Spule immer in richtiger Position.Enden 5c - Kapazitätsbestimmende Einlagen können bereits im vorkonfektionierten Leiter enthalten sein. Es entfällt das Stanzen und Einbringen von Radialbeilagen beim Wickeln einer Wicklungsanordnung.
- Bei Bedarf können auch nur eine Eingangsgruppe einer Wicklungsanordnung oder wenige Gruppen vorgefertigt werden.
- Durch den Entfall von Schutzwinkeln stellt sich eine niedrigere hot-spot Temperatur in der Wicklungsanordnung ein.
- Protective angles on the inside of winding arrangements or of coils for transformers can be omitted without replacement.
- Up to four normal double coils can be wound from twin wire.
- The free ends 5c 5d to be electrically connected to one another are always in the correct position after the coil has been wound.
- Deposits that determine capacity can already be included in the pre-assembled head. There is no need to punch and insert radial inserts when winding a winding arrangement.
- If necessary, only one input group of a winding arrangement or a few groups can be prefabricated.
- The elimination of protective angles results in a lower hot-spot temperature in the winding arrangement.
Bei der Anwendung im Hochspannungsbereich werden die Zwischenlagen 9a bis 9d bevorzugt in Stärken zwischen 0,1 bis 2 mm, insbesondere 0,3 bis 1 mm verwendet. Dabei sind Spannungsbeanspruchungen zwischen 50 bis 150 KV berücksichtigt.When used in the high-voltage range, the
