Description

Beschreibung description
Wicklungsanordnung mit Spulenwicklungen und einem Kühlkanal- System Winding arrangement with coil windings and a cooling duct system
Die Erfindung betrifft eine Wicklungsanordnung mit Spulenwicklungen und einem Kühlkanalsystem für einen elektrischen Apparat, vorzugsweise für eine ölgefüllte Drossel oder einen Transformator. The invention relates to a winding arrangement with coil windings and a cooling duct system for an electrical apparatus, preferably for an oil-filled throttle or a transformer.
Die Strömung des Kühlmittels wird in solchen Wicklungen entweder durch eine Pumpe erzwungen (OD/OF-Kühlung) oder erfolgt selbständig auf Grund der thermisch bedingten Dichteänderung der Kühlflüssigkeit (ON-Kühlung) . Die in der Wicklung erwärmte Kühlflüssigkeit steigt auf Grund des geringeren spezifi¬ schen Raumgewichts gegenüber der umgebenden Flüssigkeitsmenge auf und wird durch von unten zuströmende Kühlflüssigkeit er¬ setzt . The flow of the coolant is forced in such windings either by a pump (OD / OF cooling) or takes place automatically due to the thermally induced density change of the cooling liquid (ON cooling). The cooling liquid heated in the winding increases due to the lower ¬ specifi c region weight relative to the surrounding liquid amount and is incoming from below cooling liquid ¬ it sets.
Solche Wicklungen werden vorzugsweise als Spulen- oder Schei¬ benwicklungen ausgeführt bei denen die Kühlkanäle radial an¬ geordnet sind . In einer Vielzahl von Anwendungsfällen ist es vorteilhaft, solche Wicklungen mit radial angeordneten Kühlkanälen liegend (Wicklungsachse parallel zum Boden) einzusetzen. Such windings are preferably designed as coil or ticket ¬ benwicklungen in which the cooling channels are arranged radially to ¬ . In a large number of applications, it is advantageous to use such windings with radially arranged cooling channels (winding axis parallel to the ground).
Das Problem dabei ist, dass ab einer bestimmten radialen Breite der Wicklung in radial verlaufenden weitgehend horizontal angeordneten Kühlkanälen keine ausreichende natürliche Ölzirkulation mehr sichergestellt werden kann. The problem with this is that from a certain radial width of the winding in radially extending largely horizontally disposed cooling channels sufficient natural oil circulation can no longer be ensured.
Es ist eine Aufgabe der Erfindung, eine verbesserte Wick- lungsanordnung mit Spulenwicklungen und einem Kühlkanalsystem zu deren Kühlung anzugeben. Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 an¬ gegebenen Merkmale gelöst. It is an object of the invention to provide an improved winding arrangement with coil windings and a cooling channel system for the cooling thereof. The object is achieved by the features given in claim 1 ¬ .
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Advantageous embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Wicklungsanordnung umfasst wenigstens eine Spulenwicklung und ein Kühlkanalsystem zur Aufnahme eines Kühlmittels zur Kühlung der Spulenwicklung. Dabei sind die Spulenwicklungen um eine in einer x-Richtung verlaufende x-Achse gewickelt. Zwischen Windungen der Spulenwicklung sind Kühlkanäle des Kühlkanalsystems angeordnet. Das Kühlkanal¬ system ist derart ausgebildet, dass bei geeigneter Aus¬ richtung der Wicklungsanordnung im Erdschwerefeld und Befül- lung des Kühlkanalsystems mit dem Kühlmittel eine durch einen Stromfluss erzeugte Erwärmung der Spulenwicklungen eine Kon- vektionsströmung des Kühlmittels durch sämtliche Kühlkanäle des Kühlkanalsystems bewirkt. Mit dem Begriff Spulenwicklungen werden hier nicht nur Spulenwicklungen im wörtlichen Sinne bezeichnet, sondern auch Scheibenwicklungen . The winding arrangement according to the invention comprises at least one coil winding and a cooling channel system for receiving a coolant for cooling the coil winding. The coil windings are wound around an x-axis extending in an x-direction. Between turns of the coil winding cooling channels of the cooling channel system are arranged. The cooling channel ¬ system is designed such that in a suitable Aus ¬ direction of the winding arrangement in the earth's gravity field and filling the cooling duct system with the coolant caused by a current flow heating of the coil windings Konvektionsströmung the coolant through all the cooling channels of the cooling duct system causes. The term coil windings here not only coil windings in the literal sense, but also disc windings.
Erfindungsgemäß wird eine Strömung des Kühlmittels somit al- lein durch dessen Erwärmung durch die Spulenwicklungen erzeugt. Dies wird durch die Ausbildung des Kühlkanalsystems erreicht. Dies hat den Vorteil, dass keine weiteren Vorrich¬ tungen zur Erzeugung einer Strömung des Kühlmittels erforderlich sind. Insbesondere sind keine Pumpen zur Erzeugung einer Kühlmittelströmung erforderlich. According to the invention, a flow of the coolant is thus generated solely by its heating by the coil windings. This is achieved by the design of the cooling channel system. This has the advantage that no further Vorrich ¬ lines to generate a flow of the coolant are required. In particular, no pumps for generating a coolant flow are required.
Dadurch wird die Konstruktion der Wicklungsanordnung gegenüber aus dem Stand der Technik bekannten Wicklungsanordnungen mit gekühlten Spulenwicklungen erheblich verein- facht und verbilligt. Außerdem wird die Betriebs-sicherheit der Wicklungsanordnung erhöht, da der Wegfall von separaten Vorrichtungen zur Erzeugung einer Kühlmittel-Strömung auch die Gefahr eines Ausfalls derartiger Vorrichtungen beseitigt. Die Auslegung des Kühlkanalsystems zur Durchströmung sämtli¬ cher Kühlkanäle des Kühlkanalsystems vermeidet vorteilhaft lokale Überhitzungen von Spulenwicklungen und reduziert somit die Gefahr von Beschädigungen und Funktionseinbußen der Wicklungsanordnung durch derartige Überhitzungen. As a result, the construction of the winding arrangement with respect to winding arrangements with cooled coil windings known from the prior art is made considerably simpler and less expensive. In addition, the operational safety of the winding assembly is increased, since the elimination of separate devices for generating a coolant flow also eliminates the risk of failure of such devices. The design of the cooling channel system for the flow through sämtli ¬ cher cooling channels of the cooling channel system advantageously avoids local overheating of coil windings and thus reduces the risk of damage and loss of function of the winding assembly by such overheating.
In einer bevorzugten Ausgestaltung der Wicklungsanordnung sind die Kühlkanäle an einem Trägerkörper angeordnet. Ferner weist das Kühlkanalsystem wenigstens eine im Inneren des Trä¬ gerkörpers angeordnete Speicherkammer auf und jede Speicher¬ kammer ist über Verbindungskanäle mit Kühlkanälen verbunden. In a preferred embodiment of the winding arrangement, the cooling channels are arranged on a carrier body. Further, the cooling passage system at least one of the Trä ¬ gerkörpers arranged storage chamber inside, and each memory ¬ chamber is connected via connecting ducts with cooling channels.
In den Speicherkammern kann ausreichend Kühlmittel zur Kühlung der Spulenwicklungen zur Verfügung gestellt werden. Über die Verbindungskanäle kann das Kühlmittel aus den Speicher¬ kammern den Kühlkanälen zugeführt bzw. auf diese verteilt und aus ihnen abgeführt werden. Dadurch wird eine Kühlmittelzirkulation innerhalb des Kühlkanalsystems ermöglicht, die eine erfindungsgemäße Kühlung der Spulenwicklungen bewirkt. In the storage chambers sufficient coolant can be provided for cooling the coil windings. Via the connecting channels, the coolant from the storage ¬ chambers supplied to the cooling channels or distributed to these and removed from them. This allows a coolant circulation within the cooling channel system, which causes a cooling of the coil windings according to the invention.
Vorzugsweise ist dabei jeder Kühlkanal an einer Außenseite des Trägerkörpers angeordnet. Dadurch kann einerseits die Kühlung der Spulenwicklungen durch einen thermischen Kontakt der Kühlkanäle mit der Umgebung der Wicklungsanordnung vorteilhaft verbessert werden. Andererseits können die Kühlkanä¬ le in einfacher und effizienter Weise um die Speicherkammern im Inneren des Trägerkörpers herum angeordnet und mit diesen verbunden werden. Preferably, each cooling channel is arranged on an outer side of the carrier body. As a result, on the one hand, the cooling of the coil windings can be advantageously improved by thermal contact of the cooling ducts with the surroundings of the winding arrangement. On the other hand Kühlkanä ¬ le can be arranged in simple and efficient manner to the storage chambers inside the carrier body around and connected to these.
Von jeder Speicherkammer gehen vorzugsweise wenigstens ein erster Verbindungskanal, der wenigstens näherungsweise in ei¬ ner z-Richtung verläuft, und wenigstens ein zweiter Verbindungskanal, der wenigstens näherungsweise in einer zu der z- Richtung und der x-Richtung orthogonalen y-Richtung verläuft, aus. Diese geometrische Anordnung der von den Speicherkammern ausgehenden Verbindungskanäle ermöglicht es vorteilhaft, den durch Erwärmung der Spulenwicklungen entstehenden Auftrieb innerhalb des Kühlmittels zur Durchströmung sämtlicher Kühlkanäle des Kühlkanalsystems zu nutzen, indem die Wicklungsan¬ ordnung im Erdschwerefeld mit der z-Richtung in Richtung der Schwerkraft ausgerichtet wird. From each storage chamber, preferably at least one first connecting channel , which runs at least approximately in the z-direction, and at least one second connecting channel, which extends at least approximately in a y-direction orthogonal to the z-direction and the x-direction, exit , This geometric arrangement of the outgoing from the storage chambers connecting channels makes it possible advantageously, resulting from heating the coil windings buoyancy to use within the coolant to flow through all the cooling channels of the cooling channel system by the winding arrangement is aligned in the gravitational field with the z-direction in the direction of gravity.
Dabei verlaufen alle von Speicherkammern ausgehenden zweiten Verbindungskanäle vorzugsweise wenigstens näherungsweise in der y-Richtung. Dies ermöglicht eine geometrisch einfache und zweckmäßige Gestaltung der Verbindungskanäle zur Durchströ¬ mung der Kühlkanäle mit dem Kühlmittel. In this case, all the second connection channels emanating from storage chambers preferably extend at least approximately in the y-direction. This allows a geometrically simple and convenient design of the connecting channels for Durchströ ¬ tion of the cooling channels with the coolant.
In einer bevorzugten Ausgestaltung des Kühlkanalsystems sind dabei erste und zweite Verbindungskanäle über in der In a preferred embodiment of the cooling channel system in this case are first and second connection channels over in the
x-Richtung verlaufende dritte Verbindungskanäle mit den Kühl¬ kanälen verbunden. Die dritten Verbindungskanäle unterstützen dabei vorteilhaft die Verteilung des Kühlmittels auf die Kühlkanäle, insbesondere in der x-Richtung. X-direction extending third connection channels connected to the cooling ¬ channels. The third connection channels advantageously support the distribution of the coolant to the cooling channels, in particular in the x-direction.
In einer besonders bevorzugten Ausgestaltung weist das Kühlkanalsystem wenigstens zwei Speicherkammern auf und die Spei¬ cherkammern sind entlang der x-Richtung hintereinander angeordnet. Durch eine Mehrzahl hintereinander angeordneter Speicherkammern wird die Strömung von Kühlmittel durch das Kühlkanalsystem verbessert, indem das Kühlkanalsystem vorteilhaft segmentiert wird. In a particularly preferred embodiment, the cooling channel system comprises at least two storage chambers, and the SpeI ¬ cherkammern are arranged along the x-direction one behind the other. By a plurality of successively arranged storage chambers, the flow of coolant through the cooling channel system is improved by the cooling channel system is advantageously segmented.
In dieser Ausgestaltung sind die von benachbarten Speicherkammern ausgehenden ersten und zweiten Verbindungs-kanäle vorzugsweise versetzt zueinander angeordnet. Dadurch ergänzen sich die Strömungen aus und zu benachbarten Speicherkammern vorteilhaft, indem Kühlkanäle, die von einer Speicherkammer weniger versorgt werden, umso besser von einer benachbarten Speicherkammer versorgt werden. In this embodiment, the outgoing from adjacent storage chambers first and second connection channels are preferably arranged offset from one another. As a result, the flows from and to adjacent storage chambers complement one another in an advantageous manner in that cooling ducts, which are supplied less by one storage chamber, are better supplied by an adjacent storage chamber.
Der Trägerkörper ist vorzugsweise zylinderförmig mit einer in der x-Richtung verlaufenden Zylinderachse ausgebildet. Dies ermöglicht vorteilhaft eine geometrisch einfache Konstruktion einer erfindungsgemäßen Wicklungsanordnung. Ferner umfasst der Trägerkörper vorzugsweise mehrere Hohlzylindersegmente, deren Hohlräume jeweils eine Speicher-kammer bilden und durch Trennscheiben voneinander getrennt sind, wo- bei die von den Speicherkammern ausgehenden ersten und zweiten Verbindungskanäle Öffnungen in den Hohlzylinder-wänden der Hohlzylindersegmente sind. Auf diese Weise kann in einfa¬ cher Weise die oben beschriebene besonders bevorzugte Ausges¬ taltung der Wicklungsanordnung mit mehreren hintereinander angeordneten Speicherkammern realisiert werden. The carrier body is preferably cylindrical in shape with a cylinder axis extending in the x-direction. This advantageously allows a geometrically simple construction of a winding arrangement according to the invention. Furthermore, the carrier body preferably comprises a plurality of hollow cylinder segments whose cavities each form a storage chamber and are separated from one another by separating disks, wherein the first and second connecting channels extending from the storage chambers are openings in the hollow cylinder walls of the hollow cylinder segments. In this way, in simp ¬ cher, the above-described particularly preferred Ausges ¬ taltung the winding arrangement can be realized with a plurality of serially-arranged storage chambers.
Alternativ ist innerhalb des Trägerkörpers ein Innenkörper angeordnet und die Speicherkammern sind durch Trennscheiben voneinander getrennte Zwischenräume zwischen dem Trägerkörper und dem Innenkörper. Auch diese Ausgestaltung realisiert die besonders bevorzugte Ausgestaltung der Wicklungsanordnung mit mehreren hintereinander angeordneten Speicherkammern. Diese Ausgestaltung kann insbesondere vorteilhaft, beispielsweise als Wicklungsanordnung für Transformatoren, insbesondere Fahrzeugtransformatoren, verwendet werden. Als Trägerkörper oder Innenkörper eignen sich beispielsweise elektrische Barriereanordnungen zur Hochspannungsisolation. Wenn hochspannungstechnisch nur eine Hochspannungsbarriere erforderlich ist, kann als Innenkörper beispielsweise vorteilhaft ein Transformatorkern genutzt werden. Alternatively, an inner body is arranged within the carrier body and the storage chambers are separated by separating disks between the carrier body and the inner body. This embodiment also realizes the particularly preferred embodiment of the winding arrangement with a plurality of storage chambers arranged one behind the other. This refinement can be used particularly advantageously, for example as a winding arrangement for transformers, in particular vehicle transformers. As a carrier body or inner body, for example, electrical barrier arrangements for high voltage insulation are. If high-voltage only a high-voltage barrier is required, as an inner body, for example, advantageously a transformer core can be used.
Der Innenkörper ist dabei beispielsweise zylinderförmig ausgebildet. Dies ist besonders in Verbindung mit einem eben¬ falls zylinderförmig ausgebildeten Trägerkörper vorteilhaft, da dann gleichmäßig geformte Speicherkammern in den Zwischenräumen zwischen beiden Körpern entstehen. The inner body is for example cylindrical. This is particularly advantageous in connection with a just ¬ if cylindrical shaped carrier body, since then uniformly shaped storage chambers arise in the spaces between the two bodies.
Erfindungsgemäß wird somit eine Wicklungsanordnung vorge¬ schlagen, in der durch Kombination verschieden ausgerichteter Kanäle (Kühlkanäle, Verbindungskanäle) und anderer Kühlmit¬ telräume (Speicherkammern) jeweils Kanäle mit starkem Strö¬ mungsantrieb (weitgehend vertikale Kanäle) und Kanäle mit un¬ günstigem Kühlmittelantrieb (weitgehend horizontale Kanäle) zu einem Strömungskanal zusammengefasst werden. Durch diese Verkettung von Kanälen wird die Strömung des Kühlmittels durch die Wicklungsanordnung vergleichmäßigt und eine übermä¬ ßige Erwärmung von Teilen der Wicklung vermieden, indem ein Stagnieren der Strömung in den weitgehend horizontalen Kanälen vermieden wird. According to the invention a coil assembly is thus provided ¬ propose, in the different aligned by combining channels (coolant channels, connecting channels) and other Kühlmit ¬ telräume (storage chambers) each channels with strong Strö ¬ mung drive (largely vertical channels) and channels with un ¬ favorable coolant drive (largely horizontal channels) be summarized to a flow channel. By this concatenation of channels, the flow of the coolant is equalized through the winding assembly and a übermä ¬ ssige heating of parts of the winding avoided by stagnation of the flow is avoided in the substantially horizontal channels.

Einander entsprechende Teile sind in allen Figuren mit den gleichen Bezugszeichen versehen. Figur 1 und Figur 2 zeigen eine perspektivische Darstellung bzw. Teildarstellung eines ersten Ausführungsbeispiels einer erfindungsgemäßen Wicklungsanordnung A. Die Wicklungs- anordnung A umfasst eine Spulenwicklung 1, einen hohlzylin- derförmigen Trägerkörper 2 und ein Kühlkanalsystem, das mit einem Kühlöl als Kühlmittel zur Kühlung der Spulenwicklungen 1 befüllt wird. Die Spulenwicklung 1 verläuft helikal um eine Längsachse (Zy¬ linderachse) des Trägerkörpers 2 an dessen Außenseite. Corresponding parts are provided in all figures with the same reference numerals. Figure 1 and Figure 2 show a perspective view and partial representation of a first embodiment of a winding arrangement A according to the invention. The winding arrangement A comprises a coil winding 1, a hollow cylindrical derförmigen carrier body 2 and a cooling channel system, with a cooling oil as a coolant for cooling the coil windings 1 is filled. The coil winding 1 extends helically about a longitudinal axis (Zy ¬ linderachse) of the support body 2 on the outside thereof.
Das Kühlkanalsystem umfasst Kühlkanäle 40, die jeweils zwi¬ schen benachbarten Windungen der Spulenwicklung 1 angeordnet sind, eine Speicherkammer 20, die durch den Hohlraum im Inneren des Trägerkörpers 2 gebildet wird, und Verbindungskanä¬ le 51, 52, 53, über die die Speicherkammer 20 mit den Kühlka¬ nälen 40 verbunden ist. Erste Verbindungskanäle 51 und zweite Verbindungskanäle 52 sind Öffnungen in der Hohlzylinderwand des Trägerkörpers 2. Dabei verlaufen die ersten Verbindungskanäle 51 wenigstens näherungsweise in einer z-Richtung, die orthogonal zu einer x-Richtung ist, welche durch die Längsachse (Zylinderachse) des Trägerkörpers 2 definiert wird. Die zweiten Verbindungs¬ kanäle 52 verlaufen wenigstens näherungsweise in einer y- Richtung, welche orthogonal zu der x-Richtung und der z- Richtung ist. Die ersten und zweiten Verbindungskanäle 51, 52 führen von der Speicherkammer 20 durch die Hohlzylinderwand des Trägerkörpers 2 zu dritten Verbindungskanälen 53, die an der Außenoberfläche des Trägerkörpers 2 in x-Richtung verlau¬ fen . The cooling duct system includes cooling channels 40, each interim ¬ rule adjacent turns of the coil winding are located 1, a storage chamber 20 which is formed by the cavity inside the carrier body 2, and Verbindungskanä ¬ le 51, 52, 53, via which the storing chamber 20 is connected to the Kühlka ¬ channels 40. First connecting channels 51 and second connecting channels 52 are openings in the hollow cylinder wall of the carrier body 2. In this case, the first connecting channels 51 extend at least approximately in a z-direction which is orthogonal to an x-direction which is defined by the longitudinal axis (cylinder axis) of the carrier body 2 becomes. The second connection ¬ channels 52 extend at least approximately in a y-direction, which is orthogonal to the x-direction and the z-direction. The first and second connecting channels 51, 52 lead from the storage chamber 20 through the hollow cylinder wall of the support body 2 to the third connecting channels 53 duri ¬ fen on the outer surface of the support body 2 in the x direction.
Die dritten Verbindungskanäle 53 sind voneinander durch an der Außenoberfläche des Trägerkörpers 2 anliegende, in x-The third connection channels 53 are mutually abutting on the outer surface of the carrier body 2, in x-
Richtung verlaufende Axialleisten 3 getrennt und regelmäßig über die gesamte Außenoberfläche des Trägerkörpers 2 ver¬ teilt. Die Kühlkanäle 40 schließen sich jeweils an einen dritten Verbindungskanal 53 an und sind durch diesen von der Außen¬ oberfläche des Trägerkörpers 2 beabstandet. Sie verlaufen in einer yz-Ebene jeweils radial von einem dritten Verbindungs¬ kanal 53 nach außen. In der yz-Ebene sind die Kühlkanäle 40 durch Trennungsleisten 4 voneinander getrennt, die jeweils auf einer Axialleiste 3 aufliegen und sich von dieser zwischen benachbarten Windungen der Spulenwicklung 1 radial nach außen erstrecken. Direction extending axial strips 3 separated and regularly over the entire outer surface of the support body 2 ver ¬ shares. The cooling channels 40 connect respectively to a third connecting channel 53 and are spaced through it from the outside ¬ surface of the carrier body. 2 They run in a yz plane in each case radially from a third connection ¬ channel 53 to the outside. In the yz plane, the cooling channels 40 are separated from each other by separating strips 4, each resting on an axial strip 3 and extending radially outwardly therefrom between adjacent turns of the coil winding 1.
Figur 3 zeigt eine perspektivische Darstellung des Träger¬ körpers 2 der in den Figuren 1 und 2 dargestellten Wicklungsanordnung A mit an dem Trägerkörper 2 angeordneten Axialleis- ten 3. Figure 3 shows a perspective view of the carrier ¬ body 2 illustrated in Figures 1 and 2 with A winding arrangement is arranged on the carrier body 2 Axialleis- th. 3
Die in den Figuren 1 bis 3 dargestellte Wicklungsanordnung A ist dazu vorgesehen, im Erdschwerefeld mit der z-Richtung in Richtung der Schwerkraft ausgerichtet zu werden. Das Kühlka- nalsystem ist so konzipiert, dass bei einer derartigen Aus¬ richtung eine Erwärmung der Spulenwicklung 1, die durch einen Stromfluss durch die Spulenwicklung 1 erzeugt wird, eine Kon- vektionsströmung des Kühlöls durch sämtliche Kühlkanäle 40 des Kühlkanalsystems bewirkt. Die Konvektions-strömung wird dabei durch einen Auftrieb erzeugt, der durch die Erwärmung der Spulenwicklung 1 in dem Kühlöl entsteht. Die Anordnung insbesondere der ersten und zweiten Verbindungskanäle 51, 52 und deren näherungsweiser Verlauf in z- bzw. y-Richtung bewirken dabei, dass alle Kühlkanäle 40 in die Strömung des Kühlöls einbezogen werden. Um eine solche Strömung zu fördern, werden die zweiten Verbindungskanäle 52 vorzugsweise nicht exakt in y-Richtung verlaufend ausgeführt, sondern leicht davon abweichend, so dass sie jeweils eine aufwärts gerichtete Komponente der Strömung zulassen. The winding arrangement A shown in FIGS. 1 to 3 is intended to be oriented in the gravitational force in the gravitational field with the z-direction. Channel system the Kühlka- is designed so that in such From ¬ direction heating of the coil winding 1, which is generated by a current flow through the coil 1, a con- vektionsströmung of the cooling oil through all the cooling channels 40 of the cooling channel system causes. The convection flow is generated by a buoyancy, which is caused by the heating of the coil winding 1 in the cooling oil. The arrangement in particular of the first and second connecting channels 51, 52 and their approximate course in the z- or y-direction thereby ensure that all cooling channels 40 are included in the flow of the cooling oil. To promote such flow, the second communication passages 52 are preferably not made to run exactly in the y-direction, but slightly different, so that they each allow an upward component of the flow.
Eine Ausgestaltung des in den Figuren 1 bis 3 dargestellten ersten Ausführungsbeispiels sieht anstelle einer Spulen¬ wicklung 1 mehrere derartige Spulenwicklungen 1 vor, deren Windungen beispielsweise gegeneinander versetzt oder miteinander verflochten sind. An embodiment of the shown in the figures 1 to 3 the first embodiment provides, instead of a coil winding 1 ¬ a plurality of such coil windings 1 before, the Windings, for example, offset from each other or intertwined.
Hinsichtlich der Ausgestaltung des Kühlkanalsystems trifft Entsprechendes auch für die im Folgenden anhand der Figuren 4 bis 14 beschriebenen Ausführungsbeispiele erfindungsgemäßer Wicklungsanordnungen A zu. Auch diese weisen näherungsweise in z- bzw. y-Richtung verlaufende erste und zweite Verbin¬ dungskanäle 51, 52 auf, die eine Konvektionsströmung durch sämtliche Kühlkanäle 40 ermöglichen, wenn die Spulenwicklungen 1 von elektrischem Strom durchflössen werden und die jeweilige Wicklungsanordnung A im Erdschwerefeld mit der z- Richtung in Richtung der Schwerkraft ausgerichtet ist. Die Wicklungsanordnungen A dieser Ausführungsbeispiele weisen ebenfalls jeweils einen zylinderförmigen Trägerkörper 2 auf. Sie unterscheiden sich aber von dem ersten Ausführungsbeispiel dadurch, dass im Inneren des Trägerkörpers 2 zur weiteren Verbesserung der Konvektionsströmung des Kühlöls mehrere Speicherkammern 21, 22, 23, 24 entlang der Längsachse (Zylinderachse) des Trägerkörpers 2 hintereinander angeordnet sind. Die Längsachse des Trägerkörpers 2 definiert dabei je¬ weils wiederum eine x-Richtung. Die y- und die z-Richtung bezeichnen zu der x-Richtung und zueinander orthogonale Richtungen . With regard to the configuration of the cooling channel system, the same applies to the exemplary embodiments of inventive winding arrangements A described below with reference to FIGS. 4 to 14. These also have approximately in the z- or y-direction extending first and second connec ¬ tion channels 51, 52, which allow a convection flow through all the cooling channels 40 when the coil windings 1 are traversed by electric current and the respective winding arrangement A in the earth's gravity field the z-direction is oriented in the direction of gravity. The winding arrangements A of these embodiments also each have a cylindrical carrier body 2. However, they differ from the first embodiment in that a plurality of storage chambers 21, 22, 23, 24 along the longitudinal axis (cylinder axis) of the carrier body 2 are arranged one behind the other in the interior of the carrier body 2 for further improving the convection flow of the cooling oil. The longitudinal axis of the carrier body 2 defines each ¬ weils in turn, an x-direction. The y and z directions refer to the x-direction and mutually orthogonal directions.
Figur 4 zeigt eine perspektivische Darstellung einer Trennscheibe 5 zur Aufteilung eines zylindrischen Hohlraumes innerhalb eines hier nicht dargestellten zylindrischen Trägerkörpers 2 in zwei Speicherkammern 21, 22. Die Trenn-scheibe 5 ist dabei mittels einer entlang der Längsachse des Trägerkör¬ pers 2 angeordneten Befestigungsstange 6 an einer Tragevorrichtung 7 des Trägerkörpers 2 befestigt. Die Befestigungs¬ stange 6 kann entfallen, wenn die Trennscheibe 5 an ihrem Au¬ ßenrand mit der Innenoberfläche des Trägerkörpers 2 verbunden ist. Figure 4 shows a perspective view of a cutting wheel 5 for dividing a cylindrical cavity within a cylindrical support body 2, not shown here in two storage chambers 21, 22. The separating disk 5 is arranged by means of a arranged along the longitudinal axis of the Trägerkör ¬ pers 2 mounting rod 6 at a carrying device 7 of the support body 2 attached. The fastening ¬ rod 6 can be omitted when the blade 5 is connected at its Au ¬ ßenrand with the inner surface of the carrier body. 2
Figur 5 zeigt einen Längsschnitt in einer xz-Ebene durch ein zweites Ausführungsbeispiel einer Wicklungsanordnung A. Die Wicklungsanordnung A weist einen zylinderförmigen Trägerkörper 2 mit drei Speicherkammern 21, 22, 23 auf, die jeweils als ein Hohlraum eines Hohlzylindersegmentes innerhalb des Trägerkörpers 2 ausgebildet sind. Benachbarte Speicher- kammern 21, 22, 23 sind jeweils durch eine Trennscheibe 5 voneinander getrennt. FIG. 5 shows a longitudinal section in an xz plane through a second exemplary embodiment of a winding arrangement A. Winding arrangement A has a cylindrical carrier body 2 with three storage chambers 21, 22, 23, which are each formed as a cavity of a hollow cylinder segment within the carrier body 2. Adjacent storage chambers 21, 22, 23 are each separated by a cutting disc 5 from each other.
Von jeder Speicherkammer 21, 22, 23 gehen mehrere wenigstens annähernd in z-Richtung verlaufende erste Verbindungs- kanäle 51 und mehrere wenigstens annähernd in From each storage chamber 21, 22, 23 go several at least approximately in the z-direction extending first connecting channels 51 and several at least approximately in
y-Richtung verlaufende zweite Verbindungskanäle 52 aus, die jeweils als eine Öffnung in der Hohlzylinderwand des jeweili¬ gen Hohlzylindersegmentes ausgebildet sind. Wie im ersten Ausführungsbeispiel sind die ersten und zweiten Verbindungs- kanäle 51, 52 jeweils mit einem dritten Verbindungskanal 53 verbunden. Ebenfalls wie im ersten Ausführungsbeispiel ver¬ laufen die dritten Verbindungs-kanäle 53 in x-Richtung an der Außenoberfläche des Trägerkörpers 2 und sind mit sich nach außen anschließenden Kühlkanälen 40 verbunden, in denen Spu- lenwicklungen 1 angeordnet sind. Y direction extending second connecting channels 52, which are each formed as an opening in the hollow cylinder wall of the respec ¬ gene hollow cylinder segment. As in the first embodiment, the first and second connection channels 51, 52 are each connected to a third connection channel 53. Also as in the first embodiment ver ¬ through the third connecting passages 53 in the x-direction on the outer surface of the support body 2 and are provided with outwardly subsequent cooling channels 40 are connected, in which SPU lenwicklungen are arranged. 1
Die ersten Verbindungskanäle 51 und die zweiten Verbindungs¬ kanäle 52 benachbarter Speicherkammern 21, 22, 23 sind jeweils versetzt zueinander angeordnet. Dadurch wird die Kon- vektionsströmung des Kühlöls vorteilhaft weiter verbessert. The first connection channels 51 and the second connection ¬ channels 52 adjacent storage chambers 21, 22, 23 are each offset from each other. As a result, the convection flow of the cooling oil is advantageously further improved.
Die Figuren 6 und 7 zeigen jeweils einen Querschnitt in einer yz-Ebene durch die in Figur 5 dargestellte Wicklungsanord¬ nung A, wobei die Schnittebene in Figur 6 durch eine erste Speicherkammer 21 verläuft und die Schnittebene in Figur 7 durch eine der ersten Speicherkammer 21 benachbarte zweite Speicherkammer 22 verläuft. Dargestellt sind außerdem die Richtungen der Konvektionsströmung des Kühlöls durch die ersten und zweiten Verbindungskanäle 51, 52, die in den beiden Speicherkammern 21, 22 versetzt zueinander angeordnet sind.

Shown are also the directions of the convection flow of the cooling oil through the first and second connection channels 51, 52 which are arranged offset in the two storage chambers 21, 22 to each other.
Die Figuren 8 bis 10 zeigen jeweils eine Draufsicht auf einen entlang einer x-Richtung aufgeschnittenen und in eine xy-Ebene abgewickelten zylinderförmigen Trägerkörper 2 von Ausführungsbeispielen von Wicklungsanordnungen A, die sich durch die Anzahl von Speicherkammern 21, 22, 23, 24 und die Anzahl und/oder Verteilung von ersten und zweiten Verbin- dungskanälen 51, 52 unterscheiden, im Übrigen aber jeweils dem in den Figuren 5 bis 7 dargestellten Ausführungs-beispiel entsprechen. Dargestellt ist jeweils auch die Lage der Trenn¬ scheiben 5, die die Speicherkammern 21, 22, 23, 24 voneinander trennen. Wie in dem in den Figuren 5 bis 7 gezeigten Aus- führungsbeispiel sind die ersten und zweiten Verbindungskanä¬ le 51, 52 benachbarter Speicherkammern 21, 22, 23, 24 versetzt zueinander angeordnet. FIGS. 8 to 10 each show a plan view of a cut-and-cut along an x-direction xy plane unwound cylindrical support body 2 of embodiments of winding arrangements A, which differ by the number of storage chambers 21, 22, 23, 24 and the number and / or distribution of first and second connection channels 51, 52, but otherwise correspond to the embodiment shown in Figures 5 to 7. In each case, the position of the separating disks 5 is shown, which separate the storage chambers 21, 22, 23, 24 from one another. As in the exemplary embodiment shown in FIGS. 5 to 7, the first and second connection channels 51, 52 of adjacent storage chambers 21, 22, 23, 24 are arranged offset from one another.
Die Figuren 11 und 12 zeigen jeweils einen Querschnitt in ei- ner yz-Ebene durch eine Wicklungsanordnung A gemäß einem weiteren Ausführungsbeispiel. Dieses Ausführungsbeispiel unter¬ scheidet sich von den in den Figuren 5 bis 10 dargestellten Ausführungsbeispielen im Wesentlichen dadurch, dass die Wicklungsanordnung A keine dritten Verbindungs-kanäle 53 auf- weist, sondern die ersten und zweiten Verbindungskanäle 51, 52 direkt mit den Kühlkanälen 40 verbunden sind. Abgesehen davon ist die Wicklungsanordnung A analog zu den in den Figuren 5 bis 10 dargestellten Ausführungsbeispielen ausgebildet. Insbesondere weist sie mehrere Speicherkammern 21, 22, 23, 24 auf, wobei die von benachbarten Speicherkammern 21, 22, 23, 24 ausgehenden ersten und zweiten Verbindungskanäle 51, 52 versetzt zueinander angeordnet sind. Figur 11 zeigt einen Querschnitt, dessen Schnittebene durch eine erste Speicher¬ kammer 21 verläuft. Figur 12 zeigt einen Querschnitt, dessen Schnittebene durch eine der ersten Speicherkammer 21 benachbarte zweite Speicherkammer 22 verläuft. FIGS. 11 and 12 each show a cross section in a yz plane through a winding arrangement A according to a further exemplary embodiment. Are of this embodiment with ¬ differs from the embodiments shown in Figures 5 to 10 embodiments is essentially characterized in that the winding arrangement A has no third connecting channels 53 up but the first and second connecting channels 51, 52 connected directly to the cooling channels 40 , Apart from that, the winding arrangement A is formed analogously to the embodiments illustrated in FIGS. 5 to 10. In particular, it has a plurality of storage chambers 21, 22, 23, 24, wherein the first and second connection channels 51, 52 emanating from adjacent storage chambers 21, 22, 23, 24 are arranged offset relative to one another. Figure 11 shows a cross-section whose sectional plane passing through a first storage chamber ¬ 21st FIG. 12 shows a cross section whose sectional plane extends through a second storage chamber 22 adjacent to the first storage chamber 21.
Die Figuren 13 und 14 zeigen jeweils einen Querschnitt in ei¬ ner yz-Ebene durch eine Wicklungsanordnung A gemäß einem wei- teren Ausführungsbeispiel. Wie das in den Figuren 11 und 12 dargestellte Ausführungsbeispiel weist auch dieses Ausfüh¬ rungsbeispiel keine dritten Verbindungskanäle 53 auf. Der Un¬ terschied zu dem in den Figuren 11 und 12 dargestellten Aus- führungsbeispiel besteht in der Ausbildung der Speicherkammern 21, 22, 23, 24. Innerhalb des Trägerkörpers 2 ist ein zylinderförmiger Innenkörper 8 angeordnet, dessen Zylinderachse mit der Zylinderachse des Trägerkörpers 2 zusammen- fällt. Die Speicherkammern 21, 22, 23, 24 werden in diesem Ausführungsbeispiel von Zwischenräumen zwischen dem Trägerkörper 2 und dem Innenkörper 8 gebildet, die voneinander durch ringförmige Trennscheiben 5 voneinander getrennt sind. Abgesehen davon ist die Wicklungsanordnung A analog zu dem in den Figuren 11 und 12 dargestellten Ausführungsbeispiel aus¬ gebildet. Figur 13 zeigt einen Querschnitt, dessen Schnitt¬ ebene durch eine erste Speicher-kammer 21 verläuft. Figur 14 zeigt einen Querschnitt, dessen Schnittebene durch eine der ersten Speicherkammer 21 benachbarte zweite Speicherkammer 22 verläuft. Figures 13 and 14 show respectively a cross section in egg ¬ ner yz-plane by a winding arrangement A according to a soft direct embodiment. Like the embodiment illustrated in Figures 11 and 12 also includes exporting this example approximately ¬ no third connecting channels 53rd The Un ¬ terschied to that shown in Figures 11 and 12 off guiding example consists in the formation of the storage chambers 21, 22, 23, 24. Within the carrier body 2, a cylindrical inner body 8 is arranged, the cylinder axis coincides with the cylinder axis of the support body 2. The storage chambers 21, 22, 23, 24 are formed in this embodiment of spaces between the support body 2 and the inner body 8, which are separated from each other by annular cutting discs 5. Apart from that, the winding arrangement A is formed analogous to the embodiment shown in Figures 11 and 12 ¬ . Figure 13 shows a cross-section whose sectional ¬ plane passing through a first storage chamber 21st FIG. 14 shows a cross section whose sectional plane extends through a second storage chamber 22 adjacent to the first storage chamber 21.
Bei dem in den Figuren 13 und 14 dargestellten Ausführungsbeispiel eignen sich als Trägerkörper 2 und/oder Innenkörper 8 beispielsweise elektrische Barriereanordnungen zur Hochspannungsisolation. Dieses Ausführungsbeispiel kann ins¬ besondere vorteilhaft als Wicklungsanordnung für Fahrzeug¬ transformatoren verwendet werden. Wenn hochspannungstechnisch nur eine Hochspannungsbarriere erforderlich ist, kann als In¬ nenkörper 8 beispielsweise vorteilhaft der Kern eines Trans- formators genutzt werden. In the exemplary embodiment illustrated in FIGS. 13 and 14, suitable carrier bodies 2 and / or inner bodies 8 are, for example, electrical barrier arrangements for high-voltage insulation.
