Beschreibung description
Wicklungsanordnung mit Steckdurchführung Die Erfindung betrifft eine Wicklungsanordnung für einen Transformator oder eine Drossel mit einer aus einem Wicklungsleiter gebildeten Wicklung, einer die Wicklung umschließenden FeststoffIsolierung und einer in die FeststoffIsolierung eingebetteten Anschlusseinheit. The invention relates to a winding arrangement for a transformer or a choke with a winding formed from a winding conductor, a solid insulation enclosing the winding and a terminal unit embedded in the solid insulation.
Die Erfindung betrifft ferner ein Verfahren zum Herstellen einer Wicklungsanordnung für einen Transformator oder eine Drossel, bei dem eine aus einem Wicklungsleiter gebildete Wicklung in eine FeststoffIsolierung eingebettet wird. The invention further relates to a method for producing a winding arrangement for a transformer or a choke, in which a winding formed from a winding conductor is embedded in a solid insulation.
Eine solche Wicklungsanordnung, die auch als Trockenwicklung bezeichnet wird, ist aus der ständigen Praxis bekannt. So weisen marktübliche Transformatoren Wicklungsanordnungen auf, die aus einer Wicklung bestehen, die in eine Feststoffisolie- rung als Matrix eingebettet ist. Die vorbekannten Wicklungs¬ anordnungen sind hohlzylindrisch ausgebildet, so dass sie in ihrem Wicklungsinneren eine Unterspannungswicklung und einen aus Lamellen gebildeten Eisenkern aufnehmen kann. Wird an einer solchen vorbekannten Wicklungsanordnung daher eine Span- nung bis zu 36kV angelegt, induziert das sich im Kern aus¬ breitende Magnetfeld eine Spannung in der Unterspannungswicklung. Zum Anschluss einer Hochspannung ist die Wicklungsanordnung in der Regel mit einem Stützer ausgerüstet, mit dem ein Kabelschuh eines Hochspannungskabels verschraubbar ist. Such a winding arrangement, which is also referred to as a dry winding, is known from the constant practice. For example, commercially available transformers have winding arrangements which consist of a winding which is embedded in a solid insulation matrix. The previously known winding ¬ arrangements are hollow cylindrical, so that they can accommodate in their winding interior an undervoltage winding and an iron core formed from lamellae. Therefore, when applied to such a prior art winding arrangement, a voltage of up to 36kV, which induces in the core from ¬ wide magnetic field a voltage in the low voltage winding. To connect a high voltage, the winding assembly is usually equipped with a supporter with which a cable lug of a high voltage cable is screwed.
Darüber hinaus sind Wicklungsanordnungen bekannt, die als Anschlusseinheit eine Steckdurchführung aufweisen, wobei die Anschlusseinheit in einer Schaltleiste verbaut ist. Eine sol¬ che Wicklungsanordnung weist jedoch den Nachteil auf, dass die Ausgestaltung und Ausführung der Anschlusseinheit die Be¬ triebsspannungen begrenzt. Mit anderen Worten weist die vorbekannte Wicklungsanordnung nicht die notwendige Spannungs- festigkeit auf, um für Betriebsspannungen von über 40kV eingesetzt zu werden. In addition, winding arrangements are known which have a plug-in implementation as a connection unit, wherein the connection unit is installed in a switching strip. However, a sol ¬ che winding arrangement has the disadvantage that the design and implementation of the terminal unit limits the loading ¬ operating voltages. In other words, the previously known winding arrangement does not have the necessary voltage strength to be used for operating voltages above 40kV.
Aufgabe der Erfindung ist es daher, eine Wicklungsanordnung der eingangs genannten Art bereitzustellen, die auch bei höheren Betriebsspannungen die geforderte Spannungsfestigkeit bereitstellt . The object of the invention is therefore to provide a winding arrangement of the type mentioned, which provides the required dielectric strength even at higher operating voltages.
Die Erfindung löst diese Aufgabe dadurch, dass die Anschluss- einheit eine Steckdurchführung und zum Anschluss eines Kabel¬ steckers eingerichtet ist. The invention achieves this object in that the connection unit is a Plug-in bushing and adapted to connect a cable ¬ plug.
Im Rahmen der Erfindung wurde die Anschlusseinheit als Steck¬ durchführung ausgebildet, wobei die Steckdurchführung im Ge- gensatz zum Stand der Technik in die FeststoffIsolierung der Wicklung eingebettet ist. Eine solche Steckdurchführung unterscheidet sich von den bislang in die FeststoffIsolierung eingebetteten Stützer dadurch, dass ein am Markt erhältlicher Kabelstecker auf einfache Art und Weise mit der Steckdurch- führung verbindbar ist. Der Anschluss der Wicklungsanordnung an eine Hochspannung ist daher im Rahmen der Erfindung vereinfacht . In the present invention the connection unit has the form of plug ¬ passage, wherein the Plug-in bushing in contrast to the prior art in the solid insulation of the winding is embedded. Such a plug-in implementation differs from the supporters hitherto embedded in the solid insulation in that a cable plug available on the market can be connected to the plug-in lead-through in a simple manner. The connection of the winding arrangement to a high voltage is therefore simplified within the scope of the invention.
Steckdurchführungen sind als solche bereits bekannt und am Markt erhältlich. So kommen vorbekannte Steckverbindungen insbesondere dann zur Anwendung, wenn die Betriebsspannungen für die Wicklungsanordnung oberhalb von 40kV liegen. Im Zusammenhang mit Transformatoren werden Steckdurchführungen im Wesentlichen bei Öltransformatoren eingesetzt. Erfindungsge- mäß wird eine marktübliche Steckdurchführung bearbeitet, um anschließend in die FeststoffIsolierung der Wicklung eingebettet werden zu können. Plug-in bushings are already known as such and available on the market. Thus, known plug-in connections are used in particular when the operating voltages for the winding arrangement are above 40 kV. In connection with transformers, plug-in feedthroughs are mainly used in oil transformers. According to the invention, a commercially available plug-in feedthrough is processed so that it can subsequently be embedded in the solid insulation of the winding.
Vorteilhafterweise weist die Steckdurchführung eine genormte Kabelanschlussbuchse auf. Gemäß dieser vorteilhaften Weiter¬ entwicklung kann die Wicklungsanordnung mit Hilfe markterhältlicher genormter Kabelstecker kontaktiert werden. Darüber hinaus ist die Steckdurchführung in Abhängigkeit einer je- weils geforderten Betriebsspannung dimensioniert. Insbesonde¬ re weist die Steckdurchführung eine hierfür notwendige Spannungsfestigkeit auf. Mit anderen Worten ist die Steckdurch¬ führung in Abhängigkeit der jeweils geforderten Betriebsspan- nung dimensioniert. Advantageously, the plug-in bushing has a standardized cable connection socket. According to this advantageous further development ¬ the coil assembly can be contacted using markterhältlicher standardized connector. In addition, the plug-in implementation is dependent on a respective Weil dimensioned required operating voltage. Insbesonde ¬ re, the Plug-in bushing to a required for this dielectric strength. In other words, the Plug-in ¬ leadership is dimensioned voltage depending on the respective required Betriebsspan-.
Gemäß einer weiteren Variante der Erfindung weist jede Steckdurchführung einen Phasenleiter auf, der sich durch eine aus einem Festkörper bestehende Durchführungsisolierung er- streckt, wobei in der Durchführungsisolierung Feldsteuerele¬ mente eingebettet sind. Mit Hilfe der Feldsteuerelemente ist es möglich, hohe elektrische Feldstärken, die während des Be¬ triebs zwischen dem Phasenleiter der Steckdurchführung und dem üblicherweise auf Erdpotenzial liegenden äußeren Oberflä- che der FeststoffIsolierung entstehen können zu vermeiden. According to a further variant of the invention, each plug-in bushing has a phase conductor which extends through a feedthrough insulation consisting of a solid body, wherein field control elements are embedded in the feedthrough insulation. With the aid of control elements, it is possible high electric field strengths, the surface during loading ¬ drive between the phase conductor of the plug passageway and the normally lying on earth potential outer surface-of the solid insulation can occur should be avoided.
Zweckmäßigerweise weist die Steckdurchführung einen aus einer FeststoffIsolierung gebildeten Flanschabschnitt auf und ist über den Flanschabschnitt mit einem Aufnahmeabschnitt der FeststoffIsolierung verbunden, der an eine Außenfläche derAppropriately, the plug-in passage has a flange portion formed from a solid insulation and is connected via the flange portion with a receiving portion of the solid insulation, which is connected to an outer surface of the
FeststoffIsolierung von dieser aufragt. Gemäß dieser vorteilhaften Weiterentwicklung verfügt die FeststoffIsolierung über einen Aufnahmeabschnitt, der formkomplementär zu der der FeststoffIsolierung zugewandten Seite der Steckdurchführung ausgebildet ist. Eine solche Ausgestaltung wird beispielswei¬ se erreicht, indem die Steckdurchführung vor dem Vergießen mit einem Formteil verbunden wird. Nach dem Aushärten des Isolierstoffs wird das Formteil entfernt. Die Wicklungsanordnung weist einen in der Regel hohlzylindrischen Wicklungsinnenraum auf, der zur Aufnahme einer Unterspannungswicklung und/oder eines Schenkels eines Eisenkerns dient. Die umfänglich geschlossene Wicklung erstreckt sich dabei vollständig innerhalb der FeststoffIsolierung, deren äußere Einhüllende daher ebenfalls im Wesentlichen zylinder¬ förmig ausgebildet ist. Aus der zylinderförmigen Außenkontur ragt der Aufnahmeabschnitt im Wesentlichen rechtwinklig hervor. Ein sich durch den Aufnahmeabschnitt erstreckender elektrischer Verbindungsleiter verbindet einen Anschluss der eingebetteten Wicklung mit einem Phasenleiter der Steckdurchführung. Auf diese Weise sind alle elektrischen Leiter in einem festen Isolierstoff eingebettet, so dass sich die notwen- dige Spannungsfestigkeit ergibt. Solid insulation rises from this. According to this advantageous further development, the solid insulation has a receiving section, which is complementary in shape to the solid insulation side facing the plug passage. Such an embodiment is achieved beispielswei ¬ se by the plug-in bushing is connected before casting with a molding. After curing of the insulating material, the molded part is removed. The winding arrangement has a generally hollow-cylindrical winding interior, which serves to receive a low-voltage winding and / or a leg of an iron core. The circumferentially closed winding extends completely within the solid insulation, the outer envelope is therefore also formed substantially cylinder ¬ shaped. From the cylindrical outer contour of the receiving portion projects substantially at right angles. A extending through the receiving portion electrical connection conductor connects a terminal of the embedded winding with a phase conductor of the plug-in implementation. In this way, all electrical conductors are embedded in a solid insulating material, so that the required dielectric strength results.
Zweckmäßigerweise ist der Aufnahmeabschnitt zylinderförmig ausgebildet. Eine zylinderförmige Ausgestaltung bietet eine nach allen Seiten gleichförmige symmetrische Isolierung. Appropriately, the receiving portion is cylindrical. A cylindrical design provides a uniform symmetrical insulation on all sides.
Gemäß einer bevorzugten Ausgestaltung der Erfindung weist die Steckdurchführung eine Anschlussseite und eine der Feststoff¬ isolierung zugewandte Wicklungsseite auf, die von der An¬ schlussseite abgewandt ist. Dabei ist die Wicklungsseite mit Ausnehmungen versehen. Die Ausnehmungen erhöhen die Oberfläche der Steckdurchführung an der Seite, an der die Steckdurchführung mit der FeststoffIsolierung verbunden wird. Jede Ausnehmung vergrößert die Oberfläche der Steckdurchführung, so dass beim Aushärten der FeststoffIsolierung aufgrund der sich einstellenden stoffschlüssigen Verbindung ein festerer Halt Steckdurchführung an der FeststoffIsolierung bereitgestellt ist. Als Ausnehmung kommt beispielsweise eine umfäng¬ lich geschlossen umlaufende Kanalstruktur mit rechtwinkligem Querschnitt in Betracht. Besondere Vorteile ergeben sich je- doch, wenn die Ausnehmungen geschlossen umlaufende abgerundete Rillenstrukturen aufweisen. Eine solche Rillenstruktur ermöglicht der FeststoffIsolierung die Steckdurchführung im Bereich der Ausnehmungen zu hintergreifen, so dass neben einer stoff- auch eine formschlüssige Verbindung zwischen der aus- gehärteten FeststoffIsolierung und der Isolierung der Steckdurchführung ermöglicht ist. According to a preferred embodiment of the invention, the plug bushing, a connection side and a solid insulation ¬ facing on winding side which faces away from the on ¬ connection side. The winding side is provided with recesses. The recesses increase the surface of the plug-in feedthrough on the side at which the plug-in feedthrough is connected to the solid insulation. Each recess enlarges the surface of the push-in lead-through, so that a firmer hold on the solid insulation is provided on hardening of the solid insulation due to the adjoining cohesive connection. As a recess umfäng ¬ Lich closed peripheral channel structure is used for example with a rectangular cross section into consideration. However, special advantages arise when the recesses have closed, rounded, rounded groove structures. Such a groove structure allows the solid insulation to engage behind the plug-in feedthrough in the region of the recesses, so that not only a material but also a positive-locking connection between the hardened solids insulation and the insulation of the plug-in leadthrough is made possible.
Ausgehend von dem eingangs genannten Verfahren löst die Erfindung die Aufgabe dadurch, dass die FeststoffIsolierung an eine Steckdurchführung zum Anschluss eines Kabelsteckers angeformt wird. Erfindungsgemäß kann somit eine markterhält¬ liche Steckdurchführung an die FeststoffIsolierung der Wicklungsanordnung angeformt werden. Ein spezielles Design der Steckdurchführung ist somit überflüssig geworden. Aufwändige Eigenentwicklungen und Anpassungen der Steckdurchführung als solche sind vermieden. Gemäß einer diesbezüglich zweckmäßigen Weiterentwicklung wird die Steckdurchführung vor dem Einbetten in die FeststoffIsolierung an ihrer der FeststoffIsolierung zugewandten Wicklungsseite mit Ausnehmungen versehen. Wie bereits weiter oben ausgeführt wurde, dienen die Ausnehmungen zu einer Erhöhung der Oberfläche, so dass die FeststoffIsolierung über einen größeren Flächenbereich an der Steckdurchführung anliegt. Hierdurch ergibt sich ein fester Halt. Based on the above-mentioned method, the invention solves the problem in that the solid insulation is formed on a plug-in bushing for connecting a cable connector. According to the invention thus obtains a market ¬ Liche Plug-in bushing can be integrally formed on the solid insulation of the winding assembly. A special design of the Plug-in implementation has become superfluous. Elaborate in-house developments and adaptations of the plug-in procedure as such are avoided. According to a purposeful further development, the plug-in bushing is provided with recesses on its winding side facing the solids insulation before it is embedded in the solid insulation. As has already been explained above, the recesses serve to increase the surface, so that the solids insulation rests against the plug-in lead-through over a larger surface area. This results in a firm grip.
Weitere Vorteile ergeben sich, wenn in die Wicklungsseite um- fänglich geschlossene Rillen oder Kanäle eingefräst werden. Kanäle weisen hier eine rechteckige Struktur auf, während Rillen im Querschnitt bogenförmig ausgebildet sind. Further advantages result when grooves or channels that are completely closed in the winding side are milled in. Channels here have a rectangular structure, while grooves are arc-shaped in cross-section.

Figur 4 die Steckdurchführung der Durchführung gemäß Figure 4, the plug-in implementation of the implementation according to
Figur 1 in einer geschnittenen Seitenansicht verdeutlichen .  Figure 1 illustrate in a sectional side view.
Figur 1 zeigt ein Ausführungsbeispiel der erfindungsgemäßen Wicklungsanordnung 1 in einer perspektivischen Darstellung. Es ist erkennbar, dass die Wicklungsanordnung 1 einen zylindrischen Innenraum 2 zur Aufnahme einer Unterspannungswicklung sowie einen Schenkel eines Eisenkerns eines Transformators aufweist. Die Außenhülle oder mit anderen Worten die Außen- kontur ist im Wesentlichen zylinderförmig ausgebildet, wobei die Wicklungsanordnung 1 eine Anschlussseite 3 aufweist, die gegenüber der zylindrischen Außenhülle abgeflacht ist. An der Anschlussseite 3 ragen zwei Aufnahmeabschnitte 4 auf, die in dem gezeigten Ausführungsbeispiel zylinderförmig ausgeführt sind. Die Aufnahmeabschnitte 4 erstrecken sich rechtwinklig zu einer Mittenachse des zylindrischen Innenraums 2 und die¬ nen jeweils zur Aufnahme einer Steckdurchführung 5, wobei jede Steckdurchführung 5 mit einem scheibenförmigen Flanschabschnitt auf dem jeweiligen Aufnahmeabschnitt 4 aufsitzt. Figure 1 shows an embodiment of the winding assembly 1 according to the invention in a perspective view. It can be seen that the winding arrangement 1 has a cylindrical inner space 2 for receiving a low-voltage winding and a leg of an iron core of a transformer. The outer shell or, in other words, the outer contour is substantially cylindrical, wherein the winding arrangement 1 has a connection side 3, which is flattened with respect to the cylindrical outer shell. On the connection side 3 protrude two receiving portions 4, which are cylindrical in the embodiment shown. The receiving portions 4 extend at right angles to a center axis of the cylindrical inner space 2 and the ¬ nen each for receiving a plug-in passage 5, each plug-in bushing 5 is seated with a disc-shaped flange on the respective receiving portion 4.
Die Figuren 2 und 3 zeigen die Steckdurchführung 5 genauer. Es ist erkennbar, dass die Steckdurchführungen 5 eine Kabelseite 7 sowie eine Wicklungsseite 8 aufweisen. Dabei sind die Kabelseite 7 und die Wicklungsseite 8 durch den scheibenför- migen Flanschabschnitt 6 voneinander getrennt. Aus dem schei¬ benförmigen Flanschabschnitt 6 ragt ein Säulenabschnitt 9 hervor, der konisch oder mit anderen Worten kegelstumpfförmig ausgestaltet ist. Dabei umschließt der Säulenabschnitt 9 ei¬ nen Leiter 10, an dessen vom Flanschabschnitt 6 abgewandten freien Ende ein Gewindeanschluss 11 in Gestalt eines Innenge¬ windes ausgebildet ist. Der Säulenabschnitt 9 ist formkomple¬ mentär zu einem genormten figürlich nicht dargestellten Kabelstecker ausgeführt. Die gesamte Durchführung ist daher ebenfalls genormt, wobei die Norm beispielsweise der EN 50181 entspricht. Die Norm legt beispielsweise die Größe des Innengewindes, beispielsweise M16, und die Dimensionierung und den Typus des kegelstumpfförmigen Säulenabschnittes fest. Das Innengewinde 11 dient der Fixierung des Kabelleiters, der sich innerhalb einem Steckerkopf erstreckt. Der Steckerkopf wird über den Säulenabschnitt gestülpt. Figures 2 and 3 show the plug-in passage 5 in more detail. It can be seen that the plug-in bushings 5 have a cable side 7 and a winding side 8. In this case, the cable side 7 and the winding side 8 are separated from each other by the disk-shaped flange section 6. From the schei ¬ benförmigen flange 6 protrudes a column section 9, which is conical or in other words frusto-conical shape. In this case, the column section encloses 9 ei ¬ NEN conductor 10, at its side facing away from the flange portion 6 free end, a threaded connection 11 in the form of a Innenge ¬ wind is formed. The pillar portion 9 is designed formkomple ¬ tary to a standard cable connector not illustrated figuratively. The entire implementation is therefore also standardized, the standard corresponds to, for example, EN 50181. The standard specifies, for example, the size of the internal thread, for example M16, and the dimensions and type of the frustoconical column section. The internal thread 11 serves to fix the cable ladder, which extends within a plug head. The plug head is slipped over the column section.
Der Leiter 10 der Steckdurchführung 5 erstreckt sich von der Kabelseite 7 mittig durch den Säulenabschnitt 9 und ist auf der Wicklungsseite 8 mit einer in der FeststoffIsolierung der Wicklungsanordnung 1 angeordneten Wicklung kontaktierbar . Dabei durchragt der Leiter 10 auf der Wicklungsseite einen Stu¬ fenabschnitt 12 der Steckdurchführung 5, der in Figur 3 be- sonders gut erkennbar ist. So weist der Stufenabschnitt 12 umfänglich geschlossen umlaufende Rillen 13 als Aufnehmungen auf, mit denen die Oberfläche der Steckdurchführung 5 an der Wicklungsseite 8 vergrößert ist. Aufgrund der vergrößerten Außenfläche der Steckdurchführung 5 ist eine verbesserte Stoffschlüssige Verbindung zwischen der Steckdurchführung 5 und der FeststoffIsolierung der Wicklungsanordnung 1 ermöglicht. Abschließend sei darauf hingewiesen, dass der LeiterThe conductor 10 of the plug-in passage 5 extends centrally from the cable side 7 through the column section 9 and is on the winding side 8 can be contacted with a arranged in the solid insulation of the winding assembly 1 winding. Here, the conductor 10 extends through on the winding side, a Stu ¬ fenabschnitt 12 of the plug-in passage 5, the description is Sonders clearly seen in FIG. 3 Thus, the step portion 12 circumferentially closed circumferential grooves 13 as recesses, with which the surface of the plug-in passage 5 is increased on the winding side 8. Due to the enlarged outer surface of the plug-in bushing 5, an improved cohesive connection between the plug-in bushing 5 and the solid insulation of the winding arrangement 1 is made possible. Finally, it should be noted that the head
10 aus einem elektrisch leitenden Material besteht, der vollständig in eine aus einem Isolierstoff bestehende Durchfüh- rungsisolierung eingebettet ist. 10 consists of an electrically conductive material which is completely embedded in an existing from an insulating implementation insurance isolation.
Säulenabschnitt 9, Flanschabschnitt 6 und Wicklungsabschnitt 12 bestehen daher aus einem festen Durchführungsisolierstoff. In der Durchführungsisolierung sind ferner figürlich nicht dargestellte Feldsteuerelemente eingebettet. Column section 9, flange section 6 and winding section 12 are therefore made of a solid feedthrough insulating material. In the feedthrough insulation figuratively not shown field control elements are embedded.
Figur 4 verdeutlicht ein bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Verfahrens, bei dem die Durchführung 5 an die FeststoffIsolierung der Wicklungsanordnung 1 angeformt wird. In der gezeigten geschnittenen Seitenansicht ist erkennbar, dass sich der Leiter 10 von der KabelanschlussbuchseFigure 4 illustrates a preferred embodiment of the method according to the invention, in which the implementation of 5 is molded to the solid insulation of the winding assembly 1. In the sectional side view shown, it can be seen that the conductor 10 from the cable connection socket
11 durch die gesamte Durchführungsisolierung, die aus einem elektrisch nichtleitenden Material, beispielsweise einem zweckmäßigen Harz, besteht, hindurch erstreckt. Dabei ist der Gewindeanschluss 11 als zylindrische Sacköffnung ausgeführt. 11 through the entire feedthrough insulation, which consists of an electrically non-conductive material, such as a suitable resin, extends therethrough. In this case, the threaded connection 11 is designed as a cylindrical bag opening.
An der Wicklungsseite 8 ist in den Leiter 10 ein Wicklungsan- schluss 14 in Gestalt einer Gewindeöffnung eingebracht. Zur Vermeidung hoher Feldstärken an dem Wicklungsleiter 8 ist ei- ne metallische Abschirmanordnung oder Abschirmelement 15 mon¬ tiert. Das Abschirmelement 15 ist elektrisch leitend mit dem Leiter 10 verbunden. In Figur 4 ist weiterhin eine Gießform 16 erkennbar, die aus einer Aufnahmeabschnittsform 17 besteht, die über Verbindungsmittel 18 fest mit den restlichen Bestandteilen der Gießform 16 verbunden ist. An ihrer von den Befestigungsmit- teln 18 abgewandten Seite ist die Aufnahmeabschnittsform 17 mit Haltemitteln 19 ausgerüstet, die einen Klemmring 20 umfassen, der zum Festklemmen der Haltemittel 19 auf der Aufnahmeabschnittsform 17 eingerichtet ist. Dabei umgreift der Klemmring 20 die Aufnahmeabschnittsform 17 umfänglich. Der Klemmring 20 verfügt über eine Durchgangsöffnung mit Innengewinde, die jeweils mit einer Klemmschraube 21 im Eingriff steht. Die Klemmschrauben 21 erstrecken sich durch Klemmbügel 22 sowie durch ein Wiederlager 23, wobei das Wiederlager 23 auf der oberen Kante der Aufnahmeabschnittsform 17 aufsitzt. Zwischen den Klemmbügeln 22 und dem Wiederlager 23 erstreckt sich der Flanschabschnitt 6 der Steckdurchführung 5, so dass durch Verdrehen der Klemmschrauben 21 die Steckdurchführung 5 fest an der Aufnahmeabschnittsform 17 gehalten ist. Vor dem Verklemmen wurden in die Wicklungsseite die in Figur 3 ver- deutlichten Rillen 13 eingebracht. On the winding side 8, a winding connection 14 in the form of a threaded opening is made in the conductor 10. To avoid high field strengths at the coil conductor 8 egg ne metallic shield or shielding member 15 mon ¬ advantage. The shielding element 15 is electrically conductively connected to the conductor 10. FIG. 4 also shows a casting mold 16, which consists of a receiving section 17, which is firmly connected to the remaining constituents of the casting mold 16 via connecting means 18. On its side facing away from the fastening means 18, the receiving portion form 17 is equipped with holding means 19, which comprise a clamping ring 20 which is arranged to clamp the holding means 19 on the receiving portion 17. In this case, the clamping ring 20 surrounds the receiving portion 17 shape circumferentially. The clamping ring 20 has a through opening with internal thread, which is in each case with a clamping screw 21 in engagement. The clamping screws 21 extend through clamping brackets 22 and through a support bearing 23, wherein the abutment 23 is seated on the upper edge of the receiving portion 17 form. Between the clamping brackets 22 and the abutment 23, the flange portion 6 of the plug-in passage 5 extends, so that the plug-in bushing 5 is held firmly on the receiving portion 17 form by turning the clamping screws 21. Prior to the jamming, the grooves 13 illustrated in FIG. 3 were introduced into the winding side.
Nachdem die Steckdurchführung 5, wie in Figur 4 gezeigt, mit der Gießform 16 für die FeststoffIsolierung verbunden ist, wird die figürlich nicht dargestellte Wicklung vergossen, wo- bei der flüssige Isolierstoff, beispielsweise ein flüssigesAfter the plug-in feedthrough 5, as shown in FIG. 4, is connected to the casting mold 16 for the solid insulation, the winding, not shown in the figure, is cast, with the liquid insulating material, for example a liquid one
Harz, in die Gießform 16 gegossen wird. Anschließend wird die FeststoffIsolierung ausgehärtet und die Klemmmittel 19 und die Gießform 16 entfernt, so dass die in Figur 1 dargestellte Wicklungsanordnung 1 bereitgestellt ist. Resin is poured into the mold 16. Subsequently, the solid insulation is cured and the clamping means 19 and the mold 16 are removed, so that the winding arrangement 1 shown in Figure 1 is provided.
