Description

Die Erfindung bezieht sich auf einen Transformator, einen Wandler oder eine Drossel für mittlere bis große Leistungen nach dem Oberbegriff des Patentanspruches 1 sowie auf ein Verfahren zum Herstellen eines solchen Bauelementes. Derartige induktive Bauelemente sind prinzipiell aus der EP 0 522 475 B1 bekannt. Allerdings sind die Wicklungen dort nur für sehr viel geringere Leistungen ausgelegt.The invention relates to a transformer, a Converter or a choke for medium to large outputs according to the preamble of claim 1 and on a Method for producing such a component. Such inductive components are principally from the EP 0 522 475 B1 is known. However, the windings are there only designed for much lower performance.

Die EP 0 522 475 B1 offenbart ein induktives Bauelement, insbesondere einen Transformator mit mehreren Scheibenwicklungen. Jede Scheibenwicklung besteht aus einer relativ dünnen ebenen Metallplatte, in die ein spiralförmig umlaufender Schlitz eingebracht ist. Durch den Schlitz wird die Metallplatte zu einer planen Wicklung mit mehreren in einer Ebene nebeneinander liegenden Windungen. Die einzelnen Wicklungsscheiben werden unter Zwischenlage isolierender Schichten übereinander gestapelt und über seitlich herausgeführte Anschlüsse kontaktiert; die innenliegenden Wicklungsanschlüsse können über nachträglich einbringbare Metallstifte verbunden werden. Die Scheibenwicklungen werden über die isolierenden Zwischenlagen durch Druck- und Temperatureinwirkung zu einem allseits elektrisch isolierten Wicklungspaket verbacken. Die Wärmeabfuhr bei diesem induktiven Bauelement geschieht ausschließlich über die Oberfläche des Wicklungspaketes.EP 0 522 475 B1 discloses an inductive component, in particular a transformer with multiple windings. Each slice winding consists of a relatively thin one flat metal plate, in which a spiral revolving Slot is introduced. Through the slot is the metal plate to a flat winding with several in one level adjacent turns. The individual winding disks insulating layers are stacked on top of each other stacked and via side connections contacted; the internal winding connections can be connected via metal pins that can be inserted later become. The disc windings are insulated over the Intermediate layers due to pressure and temperature baked electrically insulated winding package on all sides. The Heat dissipation occurs exclusively with this inductive component over the surface of the winding package.

Aufgabe der Erfindung ist es, einen Transformator, einen Wandler oder eine Drossel nach dem Oberbegriff des Patentanspruches 1 so auszugestalten, dass er bzw. sie für mittlere bis große Leistungen von etwa 100 bis 3000A verwendbar ist; hieraus ergibt sich insbesondere die Forderung nach einer effektiven Wärmeabfuhr entlang der gesamten Oberfläche der verwendeten Scheibenwicklungen. Gleichzeitig soll der Montageaufwand für den zu schaffenden Transformator, Wandler oder die Drossel möglichst klein gehalten werden. Es ist ferner Aufgabe der Erfindung, ein Verfahren zum Herstellen einer solchen statischen Maschine anzugeben.The object of the invention is a transformer, a Converter or a choke according to the preamble of the claim 1 designed so that he or she for medium until large powers of around 100 to 3000 A can be used; this results in particular in the demand for an effective one Heat dissipation along the entire surface of the used Disc windings. At the same time, the assembly effort for the transformer, converter or the throttle should be kept as small as possible. It is further Object of the invention, a method for producing a to specify such a static machine.

Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1 bzw. 23. Durch das Ausschneiden von Scheibenwicklungen aus einige mm dicken Metallplatten ergibt sich die Möglichkeit, die Wicklungen auch leistungsstarker induktiver Bauelemente vollautomatisch zu fertigen, ohne daß ihre einzelnen Windungen mühevoll von Hand an eine bestimmte Formgebung angepaßt werden müssen. Die einzelnen Scheibenwicklungen können gefertigt, auch fremdgefertigt, und dann bis zur Montage in einem Lager aufbewahrt werden, aus dem sie bedarfsweise abgerufen werden können. Beim Zusammenbau der Wicklungen ist lediglich darauf zu achten, daß die einzelnen Windungen der Scheibenwicklungen auf Distanz gehalten werden und daß die benachbarten Scheibenwicklungen ebenfalls voneinander beabstandet sind; beides läßt sich durch nahezu punktförmig angreifenden Distanzelemente bewerkstelligen, die ohne großen Kraftaufwand in die Scheibenwicklungen bzw. zwischen diese einzupassen sind. Die Scheibenwicklungen sind dann lediglich noch elektrisch zu kontaktieren, wozu die Enden der einzelnen Scheibenwicklungen mit entsprechenden Mitteln auszustatten sind. Mindestens die Kontaktierung der innenliegenden Anschlüsse erfolgt bei oder nach dem Schichten der Scheibenwicklungen, auf jeden Fall aber vor dem Einsetzen eines Magnetkernes, solange die Anschlüsse für das Montagepersonal noch gut zugänglich sind. The invention solves this problem by the characterizing Features of claim 1 and 23. By cutting out Disc windings made of a few mm thick metal plates the possibility of making the windings more powerful to manufacture inductive components fully automatically without their individual turns laboriously by hand to a particular one Shape must be adjusted. The individual disc windings can be manufactured, also externally manufactured, and then be kept until assembly in a warehouse from which they can be accessed as needed. When assembling the It is only necessary to ensure that the individual windings Windings of the disk windings are kept at a distance and that the adjacent disc windings also from each other are spaced; both can be done by almost punctiform manage attacking spacer elements without great effort in the disc windings or between these have to be adjusted. The disc windings are then only still electrically contact, which is why the ends of the equip individual disk windings with appropriate means are. At least the contacting of the inside Connections are made during or after layering the windings, in any case, before inserting one Magnetic core, as long as the connections for the assembly personnel are still easily accessible.

Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Wickelgutes sind in den Unteransprüchen angegeben.Advantageous refinements and developments of the invention Wrapped goods are specified in the subclaims.

Danach soll die Metallplatte gemäß Anspruch 2 aus einer Aluminium- oder gemäß Anspruch 3 aus einer Kupferlegierung bestehen. Beide Materialien haben gute elektrische Leitfähigkeit und lassen sich problemlos auch bei dickeren Blechstärken bearbeiten.Thereafter, the metal plate according to claim 2 should consist of an aluminum or according to claim 3 of a copper alloy. Both materials have good electrical conductivity and can easily be used even with thicker sheet metal to edit.

Je nach dem, wofür die Wickelgüter zu verwenden sind, sollen die Windungen der Scheibenwicklungen in Form einer zylindrischen Spirale (Anspruch 4) oder in Form einer rechteckigen Spirale (Anspruch 5) verlaufen. Durch eine entsprechende Führung des Schlitzes ist es möglich, die Form der Scheibenwicklungen dem jeweiligen Anwendungsfall optimal anzupassen.Depending on what the winding materials are to be used for the windings of the disc windings in the form of a cylindrical Spiral (claim 4) or in the form of a rectangular Spiral (claim 5) run. With an appropriate guide of the slot it is possible to shape the disc windings to optimally adapt to the respective application.

Die Scheibenwicklung ist elektrisch isoliert auszuführen (Anspruch 6), um bei etwaigen Berührungen Querströme zu vermeiden.The disc winding must be electrically insulated (claim 6) in order to avoid cross currents when touching.

Für die elektrische Kontaktierung der Scheibenwicklungen sollen die Scheibenwicklungen gemäß Anspruch 7 endseits Kontaktierungsösen aufweisen. Damit ist es möglich, die Scheibenwicklungen gemäß Anspruch 8 zu mehreren in Reihe oder parallel zu schalten, ohne daß es hierzu irgendwelcher einpassbarer Bügel bedarf. Durch zweckmäßige Anordnung der Ösen fluchten diese sowohl dann, wenn die Scheibenwicklungen parallel als auch dann, wenn sie in Reihe geschaltet werden sollen.For the electrical contacting of the disc windings the disk windings according to claim 7 at the end contacting eyelets exhibit. It is possible to use the disc windings according to claim 8 to several in series or in parallel to switch without this being any customizable Bracket required. Align by appropriate arrangement of the eyelets both when the disc windings are parallel as well as if they are to be connected in series.

Die Kontaktierung der einzelnen Scheibenwicklungen erfolgt nach der Lehre des Anspruches 9 über Schraubverbindungen oder gemäß Anspruch 10 über elektrisch kontaktierende Druckknöpfe, wie sie prinzipiell zur Kontaktierung von Batterien bekannt sind; Anspruch 11 sieht die Kontaktierung der Windungen über hart gelötete Flansche vor.The individual disc windings are contacted according to the teaching of claim 9 about screw connections or according to claim 10 via electrically contacting push buttons, as they are known in principle for contacting batteries are; Claim 11 sees the contacting of the turns brazed flanges.

Als besonders zweckmäßig wird angesehen, wenn die Distanzelemente nach der Lehre des Anspruches 12 zur Separierung der Windungen der einzelnen Scheibenwicklungen gleichzeitig auch zum Separieren benachbarter Scheibenwicklungen verwendet werden. Dies wird erreicht, wenn die Distanzelemente gemäß Anspruch 13 z. B. die Form von Stiften mit endseitigen Flanschen oder mittig umlaufenden Kragen aufweisen, wobei die Stifte zwischen die benachbarten Windungen fassen und die Flansche oder die umlaufenden Kragen die einzelnen Scheibenwicklungen auf Abstand halten.It is considered particularly useful if the spacer elements according to the teaching of claim 12 for the separation of Windings of the individual disk windings at the same time be used to separate adjacent disc windings. This is achieved if the spacer elements according to claim 13 z. B. the shape of pins with end flanges or have a circumferential collar, the Grip the pins between the adjacent turns and the Flanges or the circumferential collar the individual disc windings keep your distance.

Die Stifte könne gemäß Anspruch 14 vorteilhaft als Schrauben ausgeführt sein, die in entsprechende Gewindebohrungen der Scheibenwicklungen einzuschrauben oder in Durchgangslöcher der Scheibenwicklungen einzustecken und dort über Muttern zu halten sind.The pins could advantageously as screws according to claim 14 be carried out in the corresponding threaded holes Screw in windings or in through holes of the windings and plug them in there with nuts are holding.

Die Distanzelemente sind dabei gemäß Anspruch 15 in den Schlitzen oder in gesonderten Ausnehmungen der Scheibenwicklungen gehalten. Sie lassen sich so über die Oberfläche der Scheibenwicklungen verteilt anordnen und halten die Scheibenwicklungen auf Abstand, ohne die Luftzirkulation zwischen den Scheibenwicklungen nennenswert zu beeinträchtigen. Bei Halterung der Distanzelemente in den Schlitzen sorgen sie gleichzeitig auch für eine Separierung der einzelnen Windungen der Scheibenwicklungen. The spacer elements are according to claim 15 in the Slots or in separate recesses in the disk windings held. They can be seen on the surface of the Arrange the disk windings in a distributed manner and hold the disk windings at a distance without the air circulation between the Noticeably affect disc windings. With bracket the spacer elements in the slots ensure them at the same time also for a separation of the individual turns of the Disc windings.

Die Distanzelemente können bei geeigneter Ausgestaltung auch in die Schlitze bzw. Ausnehmungen zweier benachbarter Scheibenwicklungen eingreifen und so gemäß Anspruch 16 gleichzeitig zwei Scheibenwicklungen separieren und gegeneinander ausrichten.With a suitable design, the spacer elements can also into the slots or recesses of two adjacent disc windings intervene and so according to claim 16 simultaneously Separate two disc windings and align them against each other.

Es ist aber auch möglich, die Scheibenwicklungen gemäß Anspruch 17 über Isolierstangen auszurichten, wobei die Isolierstangen gleichzeitig dazu verwendet sein können, die Windungen der einzelnen Scheibenwicklungen zu separieren. Durch während der Montage auf die Isolierstangen auf steckbare Isolationsscheiben oder Isolationsrohre gemäß Anspruch 18 lassen sich die einzelnen Scheibenwicklungen auf Abstand halten.However, it is also possible to use the disk windings as claimed Align 17 over insulating rods, the insulating rods the windings can be used simultaneously to separate the individual disk windings. By during assembly on the insulating rods on pluggable insulating washers or leave insulation pipes according to claim 18 keep the individual disc windings at a distance.

Die Isolierstangen können gemäß Anspruch 19 über Sicherungsscheiben im fertig montierten Scheibenwicklungsblock dauerhaft fixiert sein.The insulating rods can according to claim 19 via locking washers permanently in the assembled disc winding block be fixed.

Die Isolierstangen können gemäß Anspruch 20 vorteilhaft als Metallstangen oder Metallrohre ausgebildet sein, die nach außen hin elektrisch isoliert sind oder in isolierende Buchsen in den Scheibenwicklungen fassen.The insulating rods can advantageously as claimed in claim 20 Metal rods or metal pipes are formed, which face the outside are electrically insulated or in insulating sockets grasp in the windings.

Für die Aufnahme der Distanzelemente können die benachbarten Windungen der Scheibenwicklungen gemäß Anspruch 21 mit aufeinander weisenden Ausnehmungen versehen sein. Dies macht es möglich, die als Distanzelemente verwendeten Stifte relativ großvolumig und damit gut handhabbar auszuführen. In vorteilhafter Weise sind die Kanten der Ausnehmungen für die Stifte gemäß Anspruch 22 zu brechen. Theoretische Betrachtungen zeigen, daß an scharfen Kanten beim Beaufschlagen der Wicklungswindungen mit Speisespannungen hohe Feldstärken auftreten und The neighboring ones can be used to accommodate the spacer elements Windings of the disk windings according to claim 21 with one another facing recesses. It does it possible, the pins used as spacers relative large volume and therefore easy to handle. In advantageous Ways are the edges of the recesses for the pins to break according to claim 22. Theoretical considerations show that on sharp edges when loading the winding turns high field strengths occur with supply voltages and

dadurch Spannungsüberschläge an diesen Stellen verstärkt auftreten können.this leads to increased voltage flashovers at these points can.

Das erfindungsgemäße Verfahren zum Herstellen von Scheibenwicklungen für Transformatoren, Wandler oder Drosseln mittlerer bis großer Leistung besteht gemäß Anspruch 23 im Ausschneiden der Scheibenwindungen aus ebenen dickwandigen Metallplatten, wobei in die Metallplatten durch bestimmte Bearbeitungsverfahren jeweils ein der Wicklungskontur folgender Schlitz eingebracht wird.The method according to the invention for producing disc windings for medium-sized transformers, converters or chokes to great performance consists in cutting according to claim 23 the disc windings made of flat, thick-walled metal plates, being in the metal plates by certain machining processes one each following the winding contour Slot is introduced.

Die elektrische Isolierung der Scheibenwicklung soll gemäß Anspruch 24 vorzugsweise durch ein Wirbelsinterverfahren hergestellt werden.The electrical insulation of the disc winding is said to Claim 24 preferably produced by a vortex sintering process become.

Mindestens die innenliegenden Anschlüsse der Scheibenwicklungen werden gemäß Anspruch 25 kontaktiert, solange sie noch zugänglich sind.At least the internal connections of the disc windings be contacted according to claim 25 while they are still are accessible.

Die Scheibenwicklungen sind zu ihrer Parallelschaltung zu mehreren mit gleichem Wicklungssinn und zu ihrer Reihenschaltung zu mehreren mit unterschiedlichem Wicklungssinn ihrer Windungen übereinanderzuschichten, zu separieren und miteinander elektrisch leitend zu verbinden. Diese Verbindungen sind in der Zeichnung aus Gründen der Übersichtlichkeit nicht dargestellt. Die Kontaktierung erfolgt über endseits in die Windungen eingelassene offene oder geschlossene Ösen vorzugsweise mittels Schraubverbindungen. Die Kontaktierungen können aber auch in vorteilhafter Weise über elektrisch kontaktierende Druckknöpfe oder Verlötungen vorgenommen werden.In the disc winding shown in the right part of Figure 1 it is a winding, like it on one rectangular core can be put on; their turns 1 to 4 run around a in the form of a rectangular spiral common axis.

The spacer elements exist preferably from a pin-like structure with circular or rectangular cross-section, in the intended Insert recesses 16 of adjacent winding windings is. These recesses, one of which is shown in FIG is shown enlarged, are in pairs in neighboring Windings of the disc windings, taking them with their openings face each other. The edges of the Recesses are broken at 17.

Die Distanzelemente bestehen aus einem wärmefesten elektrisch isolierenden Werkstoff. Sie halten benachbarte Windungen auf Abstand, wobei sie, wie in Figur 1 angenommen, nicht unbedingt zwischen jede benachbarte Windung sondern nur zwischen jede zweite Windung eingesetzt werden können.The spacer elements consist of a heat-resistant electrical insulating material. They stop neighboring turns Distance, whereby, as assumed in Figure 1, not necessarily between each adjacent turn but only between every second turn can be used.

Die Distanzelemente sind mit einem etwa mittig umlaufenden Kragen 18 oder einem endseitigen Flansch versehen, dessen Dicke den Abstand der Scheibenwicklungen voneinander vorgibt; ein solcher Flansch kann z.B. durch den Kopf einer wärmefesten Kunststoffschraube gebildet sein, auf die zur Vorgabe bestimmter Abstände zwischen den Scheibenwicklungen gegebenenfalls eine oder mehrere Unterlegscheiben aufzustecken sind. Die Schrauben können in entsprechende Gewindelöcher der Scheibenwicklungen eingedreht und/oder in Durchgangslöcher der Scheibenwicklungen eingesteckt und dort mittels von der Gegenseite der Scheibenwicklungen angreifenden Muttern gehalten sein. Über die Kragen bzw. Flansche werden die benachbarten Scheibenwicklungen elektrisch isoliert auf Distanz gehalten. Die Dicke der Kragen/Flansche liegt bevorzugt in der Größenordnung von etwa 0.5 bis einigen mm. Die Breite der einzelnen Windungen liegt bevorzugt in der Größenordnung von 10 bis 25 mm, die Dicke bei etwa 5 bis 12 mm: die Schlitzbreite liegt zwischen etwa 0,5 und einigen mm.The spacer elements have an approximately circumferential one Collar 18 or an end flange provided, the thickness specifies the distance between the disk windings from one another; such a flange can e.g. through the head of a heat-resistant Plastic screw to be formed on the specified Clearances between the windings if necessary one or more washers are to be attached. The screws can be screwed into the corresponding threaded holes Disc windings screwed in and / or in through holes the disc windings inserted and there by means of the Nuts on the opposite side of the disk windings are held his. The neighboring ones are over the collars or flanges Disc windings are kept electrically insulated at a distance. The thickness of the collar / flanges is preferably in the On the order of about 0.5 to a few mm. The width of the individual turns is preferably of the order of magnitude 10 to 25 mm, the thickness at about 5 to 12 mm: the slot width is between about 0.5 and a few mm.

Anstelle einer von der Zahl der jeweils übereinander anzuordnenden Scheibenwicklungen abhängigen Anzahl von stift- oder schraubenförmigen kurzen Distanzelementen ist es auch möglich, die Scheibenwicklungen über eine Anzahl von Isolierstangen mit aufgefädelten Isolierscheiben oder Isolierrohren zu separieren. Die Stangen durchdringen dabei die übereinander angeordneten Scheibenwicklungen, wobei sie deren einzelne Windungen gegeneinander ausrichten; sie sind über endseitige Anschläge zwischen den äußeren Scheibenwicklungen gehalten. Die benachbarten Scheibenwicklungen werden durch auf die Isolierstäbe aufgesteckte scheiben- oder rohrförmige Distanzelemente voneinander getrennt. Die Isolierstäbe können die einzelnen Windungen durchdringen; sie können auch in die Wicklungsschlitze eingesetzt sein. Die Windungen können dabei mit seitlich in die Schlitze vorstehenden Nasen versehen sein, die über Lochungen dazu eingerichtet sind, die Isolierstäbe aufzunehmen. Dadurch wird erreicht, dass die Isolierstäbe in den benachbarten Scheibenwicklungen jeweils benachbarte Windungen durchdringen, wodurch die Separierung der Windungen innerhalb der einzelnen Scheibenwicklungen verbessert wird.Instead of one of the number of those to be arranged one above the other Disc windings dependent number of pin or helical short spacer elements it is also possible the disc windings over a number of insulating rods with threaded insulation washers or insulation tubes to separate. The rods penetrate the one above the other arranged disc windings, being their individual Align turns against each other; they are over-ended Stops held between the outer disc windings. The adjacent disc windings are through on the insulating rods attached disc or tubular spacers separated from each other. The insulating rods can do the individual Penetrate coils; they can also be in the winding slots be used. The turns can be used lugs protruding laterally into the slots, which are set up via perforations, the insulating rods to record. This ensures that the insulating rods in adjacent windings each adjacent windings penetrate, causing the separation of the turns is improved within the individual disk windings.

Durch die Verwendung von insgesamt kleinvolumigen Distanzelementen, die auf den einzelnen Scheibenwicklungen nur quasi punktförmig anliegen, ist es möglich, die Scheibenwicklungen zur Wärmeabfuhr optimal zu belüften. Die Wärmeabfuhr geschieht durch Konvektion in Folge von Leitungserwärmung der Scheibenwicklungen oder durch Zuführen von Kühlluft, welche den Freiraum zwischen den Scheibenwicklungen durchströmt. Through the use of small overall spacer elements, that on the individual disk windings only quasi it is possible to place the disc windings optimal ventilation for heat dissipation. The heat dissipation happens by convection as a result of line heating Disc windings or by supplying cooling air, which flows through the space between the windings.

Die Scheibenwicklungen werden im Gegensatz zu herkömmlichen Scheibenwicklungen nicht durch Aufwickeln isolierter Drähte oder Leitungsprofile gebildet, sondern sie werden aus ebenen Metallplatten ausgeschnitten. Diese Metallplatten bestehen aus einem elektrisch gut leitendem Werkstoff, vorzugsweise einer Aluminium- oder Kupferlegierung, in die ein der Windungskontur folgender Schlitz vorgegebener Breite eingebracht ist. Dieses Schlitzen der Metallplatte erfolgt durch Sägen, Nibbeln, Ätzen, Erodieren, durch einen Wasserschneidevorgang, durch Schweißen oder durch Laserbearbeitung, wobei möglicherweise jeweils mehrere übereinandergeschichtete Metallplatten gleichzeitig bearbeitet werden können. Schon beim Ausschneiden der einzelnen Windungen können die Ausnehmungen für die elektrische Kontaktierung und/oder die Aufnahme der Distanzelemente in die Metallplatte eingebracht werden, so daß sich zusätzliche Arbeitsgänge für das Einbringen entsprechender Konturen erübrigen. Die elektrische Isolierung der Scheibenwicklungen geschieht vorzugsweise durch Anwendnung eines Wirbelsinterverfahrens, wobei die Kontaktierungsflächen der Wicklungen während des Sintervorganges abzudecken oder erst nachträglich hergestellt werden.The disc windings are in contrast to conventional ones Disc windings not by winding insulated wires or line profiles are formed, but they are made up of levels Cut out metal plates. These metal plates are made made of an electrically highly conductive material, preferably an aluminum or copper alloy into which one of the winding contours following slot of predetermined width introduced is. This slitting of the metal plate is done by sawing, Nibbling, etching, eroding, through a water cutting process, by welding or by laser machining, possibly several metal sheets stacked on top of each other can be edited at the same time. Already when cutting out of the individual turns, the recesses for the electrical contacting and / or the inclusion of the spacer elements be introduced into the metal plate so that additional operations for the introduction of appropriate Eliminate contours. The electrical insulation of the disc windings is preferably done by using a vortex sintering process, the contact surfaces of the Cover windings during the sintering process or only can be produced subsequently.

Der Aufbau eines Transformators, eines Wandlers oder einer Drossel geschieht in der Weise, daß die einzelnen Scheibenwicklungen unter Einfügen der die Wicklungen und die Windungen separierenden Distanzelemente übereinander gesteckt und elektrisch kontaktiert werden. Für die Kontaktierung sind die dafür in die Windung oder die Windungen eingebrachten Ösen 5 und 6 so anzuordnen, dass die Möglichkeit besteht, durch Wenden der benachbarten Wicklungen um 180° um deren Längsachse bedarfsweise zu einer Reihen- oder Parallelschaltung benachbarter Scheibenwicklungen zu kommen. Selbstverständlich ist es auch möglich, die Wicklungsenden der Scheibenwicklungen mit mehreren Ösen zu versehen und diese Ösen möglicherweise noch mit einem Gewinde zur Aufnahme von Kontaktierungsschrauben zu versehen. Desgleichen ist es möglich, die Ausnehmungen ebenfalls mit Gewinden zur Aufnahme von Distanzelementen auszubilden, die auf ihrer Oberfläche eine entsprechende Gewindestruktur aufweisen. Dies hätte den Vorteil, daß die Distanzelemente in die Windungen eingeschraubt werden können und dann in den einzelnen Scheibenwicklungen lagestabil fixiert wären, was die Montage der elektrischen Maschine erleichtern würde; das hätte aber zur Voraussetzung, daß in die Ausnehmungen in einem zusätzlichen Arbeitsgang Gewinde eingebracht werden müßten. Vorteilhafter ist es, die Distanzelemente mit federnden Rasten oder mit aufspreizbaren Hülsen zu versehen, die beim Einstecken in die Ausnehmungen benachbarter Windungen zusammengedrückt werden und in ihrer Montageposition auseinanderfedern und sich so zwischen den Windungen der einzelnen Scheibenwicklungen fixieren. Dem gleichen Zweck kann auch das Anheften von Distanzelementen zwischen den Windungen einer Scheibenwicklung über ein Klebverbindung dienen.The construction of a transformer, a converter or one Choke happens in such a way that the individual disk windings inserting the the windings and the turns separating spacer elements one above the other and be contacted electrically. For contacting are the for this purpose, eyelets introduced into the turn or turns 5 and 6 so that there is the possibility of turning of the adjacent windings by 180 ° about their longitudinal axis if necessary to a series or parallel connection of neighboring Disc windings to come. It goes without saying it is also possible to use the winding ends of the disc windings to be provided with several eyelets and these eyelets possibly still with a thread for receiving contacting screws to provide. It is also possible to make the recesses also with threads to accommodate spacer elements, the corresponding thread structure on their surface exhibit. This would have the advantage that the spacer elements can be screwed into the turns and then fixed in position in the individual disk windings would be what facilitate the assembly of the electrical machine would; but that would have to be a prerequisite that in the recesses Threaded in an additional step should be. It is more advantageous to use the spacer elements to provide resilient catches or with expandable sleeves, when inserted into the recesses of adjacent turns be compressed and spring apart in their mounting position and so between the turns of the individual Fix the disc windings. The same purpose can also attaching spacers between turns of one Serve disc winding via an adhesive connection.

Sind Scheibenwicklungen auch oder ausschließlich mit innenliegenden Windungsanschlüssen versehen, so werden diese während oder nach dem Zusammenbau der Wicklungspakete kontaktiert, auf jeden Fall vor dem Einbringen der Kernelemente, die die Zugänglichkeit der Wicklungsanschlüsse beeinträchtigen oder versperren würden.Are disc windings also or exclusively with internal ones Provided turn connections, so these are during or contacted after assembling the winding packages, in any case before inserting the core elements, that affect the accessibility of the winding connections or would block.
