The function of the blocks 70 is also to adjust the low voltage coil 30 relative to the high voltage coil 40 and relative to the core leg 10.
Die Figur 2 zeigt beispielhaft die Ausgestaltung der Klötze 70 gemäß Figur 1 im Querschnitt. Man erkennt einen Spulenab¬ schnitt 30a der Unterspannungsspule sowie einen Spulenab- schnitt 40a der Oberspannungsspule, die durch einen Justier¬ stift 80 des Klotzes 70 voneinander getrennt und somit zuein¬ ander justiert werden. FIG. 2 shows by way of example the configuration of the blocks 70 according to FIG. 1 in cross section. One recognizes a Spulenab ¬ section 30a of the low voltage coil and a Spulenab- section 40a of the high voltage coil, the adjusting member 80 by a pin ¬ of the block 70 separated from each other, and thus be adjusted zuein ¬ other.
Anhand der Figuren 3 bis 6 wird nachfolgend beispielhaft ein Ausführungsbeispiel für einen erfindungsgemäßen Transformator sowie ein Ausführungsbeispiel für das erfindungsgemäße Ver¬ fahren erläutert. Die Figuren 3 bis 6 zeigen hierzu beispiel¬ haft die Anordnung einer Unterspannungsspule des Transforma¬ tors relativ zu dem zugeordneten Kernschenkel des Transforma- torkerns . An exemplary embodiment of a transformer according to the invention and an exemplary embodiment of the method according to the invention are explained below by way of example with reference to FIGS. 3 to 6. Figures 3 to 6 show, for this purpose ¬ way of the arrangement of a low voltage coil of the transformers ¬ gate relative to the associated core leg of the transformer torkerns.
In der Figur 3 erkennt man die Unterspannungsspule, die mit dem Bezugszeichen 100 gekennzeichnet ist. Der Kernschenkel, der die Unterspannungsspule 100 durchsetzt, ist in der Figur 3 nicht erkennbar. Er wird durch das Joch 110 des Transforma¬ torkernes verdeckt. FIG. 3 shows the undervoltage coil, which is identified by the reference numeral 100. The core leg, which passes through the undervoltage coil 100, can not be seen in FIG. It is covered by the yoke 110 of Transforma ¬ torkernes.
In der Figur 4 ist die Anordnung der Unterspannungsspule 100 relativ zum Kernschenkel im Querschnitt entlang der Schnitt- linie I-I' gemäß Figur 3 dargestellt. Man erkennt in der Fi¬ gur 4, dass der Kernschenkel 120 ein Kernblechpaket 130 auf¬ weist, das aus einer Vielzahl an in der Figur 4 vertikal verlaufenden Transformatorkernblechen gebildet ist. Die Trans- formatorkernbleche sind in der Figur 4 aus Gründen der Übersicht nicht explizit dargestellt, das Kernblechpaket 130 ist lediglich als Ganzes durch eine Schraffur gekennzeichnet. Die Transformatorkernbleche des Kernblechpakets 130 werden beispielsweise durch zwei Zugankerbleche und zwei oder mehr (z. B. drei) Kernbolzen zusammengepresst ; zusätzlich oder alternativ können zum Zusammenpressen auch Kernbandagen eingesetzt werden. Dabei ist beispielsweise ein erstes Zuganker- blech 140 an einer ersten (in der Figur 4 rechten) Seitenfläche 150 des Kernblechpakets 130 angebracht; ein zweites Zug¬ ankerblech 160 befindet sich an der gegenüberliegenden zweiten (in der Figur 4 linken) Seitenfläche 165 des Kernblechpa¬ kets 130. Die beiden Zugankerbleche 140 und 160 sind durch die drei Kernbolzen miteinander verbunden, die in der Figur 4 mit den Bezugszeichen 170, 171 und 172 gekennzeichnet sind. Die drei Kernbolzen 170, 171 und 172 sind - zumindest nähe¬ rungsweise - senkrecht zur Längsrichtung des Kernschenkels 120 ausgerichtet. FIG. 4 shows the arrangement of the undervoltage coil 100 relative to the core limb in cross section along the section line II 'according to FIG. It can be seen in Fi gur ¬ 4, that the core arms 120 has a core sheet package 130 ¬ formed of a plurality of vertically extending in the figure 4 transformer core sheets. The trans- For the sake of clarity, core plates are not explicitly shown in FIG. 4; the core plate package 130 is only indicated as a whole by a hatching. The transformer core laminations of the core lamination stack 130 are pressed together, for example, by two tie plates and two or more (eg, three) core bolts; Additionally or alternatively, core bandages can also be used for compression. In this case, for example, a first tie rod sheet 140 is attached to a first (right in FIG. 4) side face 150 of the core lamination stack 130; a second pull ¬ anchor plate 160 is located on the opposite second (left in Figure 4) side surface 165 of Kernblechpa ¬ kets 130. The two Zugankerbcheche 140 and 160 are interconnected by the three core bolts, which in the figure 4 by the reference numeral 170th , 171 and 172 are marked. The three core pins 170, 171 and 172 are - at least approximately ¬ approximately - aligned perpendicular to the longitudinal direction of the core limb 120.
In der Figur 4 lässt sich darüber hinaus erkennen, dass die Unterspannungsspule 100 konzentrisch zum Kernschenkel 120 justiert ist und an dem Kernschenkel 120 mittels zweier Fi¬ xierbolzen 200 und 210 befestigt ist. Die beiden Fixierbolzen 200 und 210 erstrecken sich senkrecht, zumindest annähernd senkrecht, zur Längsachse der Unterspannungsspule 100 und da¬ mit senkrecht, zumindest annähernd senkrecht, zur Längsachse des Kernschenkels 120. Die Befestigung der Unterspannungsspule 100 an dem Kernschenkel 120 mittels der beiden Fixierbolzen 200 und 210 ist in den Figuren 5 und 6 näher im Detail gezeigt; dabei zeigt die Figur 5 die in der Figur 4 mit dem Bezugszeichen B gekenn- zeichnete Einzelheit und die Figur 6 die in der Figur 4 mit dem Bezugszeichen C näher gekennzeichnete Einzelheit. In the figure 4 it can be seen furthermore that the low voltage coil is concentrically aligned with respect to the core leg 120 100 and is attached to the core leg 120 by means of two Fi ¬ xierbolzen 200 and 210th The two fixing bolts 200 and 210 extend vertically, at least approximately perpendicularly, to the longitudinal axis of the undervoltage coil 100 and there ¬ perpendicular, at least approximately perpendicular to the longitudinal axis of the core leg 120. The attachment of the undervoltage coil 100 to the core limb 120 by means of the two fixing bolts 200 and 210 is shown in greater detail in FIGS. 5 and 6; FIG. 5 shows the reference number B indicated in FIG. drew particulars and the figure 6 in Figure 4 with the reference C more marked detail.
Man erkennt in den Figuren 5 und 6, dass das erste Zuganker- blech 140 und damit der Kernschenkel 120 zwei Bolzenhalteaus- nehmungen 220 und 230 aufweisen. Die Bolzenhalteausnehmungen 220 und 230 sind durch Durchgangslöcher gebildet, die das erste Zugankerblech 140 vollständig durchsetzen, so dass das erste Bolzenende 240 der beiden Fixierbolzen 200 und 210 un- mittelbar auf dem äußersten Transformatorkernblech des Kernblechpaketes auf der ersten Seitenfläche aufliegen kann. Das zweite Bolzenende 250 der beiden Fixierbolzen 200 und 210 ist in zwei Einhängausnehmungen 260 und 270 in der Unterspannungsspule 100 eingehängt. It can be seen in FIGS. 5 and 6 that the first tie rod sheet 140 and thus the core limb 120 have two bolt holding recesses 220 and 230. The bolt holding recesses 220 and 230 are formed by through holes which completely pass through the first tie plate 140, so that the first bolt end 240 of the two fixing bolts 200 and 210 can rest directly on the outermost transformer core of the core package on the first side surface. The second bolt end 250 of the two fixing bolts 200 and 210 is suspended in two Einhängausnehmungen 260 and 270 in the lower voltage coil 100.
Wie sich in den Figuren 4 bis 6 erkennen lässt, ist die Unterspannungsspule 100 mit einem elektrischen Anschlussblech 280 ausgestattet, das einen elektrischen Spulenanschluss der Unterspannungsspule 100 bildet. In diesem elektrischen An- schlussblech 280 sind zwei Durchgangslöcher vorhanden, die die Einhängausnehmungen 260 und 270 in der Unterspannungsspu¬ le 100 bilden. Das elektrische Anschlussblech 280 bildet so¬ mit anschaulich die Innenseite 290 der Unterspannungsspule 100, die die Außenfläche des Kernblechpakets 130 konzentrisch umgibt. As can be seen in FIGS. 4 to 6, the undervoltage coil 100 is equipped with an electrical connection plate 280, which forms an electrical coil connection of the undervoltage coil 100. In this electrical connections circuit sheet 280, two through holes are provided which form in the Unterspannungsspu ¬ le 100 Einhängausnehmungen the 260 and 270th The electric terminal plate 280 is so ¬ with clearly the inner side 290 of the low voltage coil 100 surrounding the outer surface of the core stack 130 concentrically.
Um eine konzentrische Justage der Unterspannungsspule 100 re¬ lativ zu dem Kernblechpaket zu gewährleisten, ist zwischen dem ersten Zugankerblech 140 sowie dem elektrischen An- schlussblech 280 eine Distanzeinrichtung in Form zweier Distanzelemente 300 und 310 vorgesehen. Die beiden Distanzele¬ mente 300 und 310 können beispielsweise durch Distanzplatten oder Distanzscheiben gebildet sein, die vorzugsweise aus ei- nem elektrisch nicht leitenden Material bestehen. Die Distanzelemente 300 und 310 können beispielsweise aus Kunst¬ stoff, insbesondere glasfaserverstärktem Kunststoff, beste¬ hen. Die beiden Distanzelemente 300 und 310 bewirken einen Mindestabstand zwischen dem ersten Zugankerblech 140 bzw. der in den Figuren 5 und 6 rechten Seitenfläche des Kernschenkels 120 und dem elektrischen Anschlussblech 280 der Unterspannungsspule 100. Die beiden Fixierbolzen 200 und 210 können jeweils mit ihrem zugeordneten Distanzelement 300 bzw. 310 einteilig verbunden sein. Vorzugsweise bilden der Fixierbolzen 200 und das Distanzelement 300 ein gemeinsames Bauteil und in entsprechender Weise der Fixierbolzen 210 und das Distanzelement 310 ein weiteres gemeinsames Bauteil. Im Falle einer solchen Ausge¬ staltung bestehen die Fixierbolzen und die zugehörigen Distanzelemente vorzugsweise aus demselben Kunststoff, insbeson¬ dere aus demselben glasfaserverstärktem Kunststoff. Sind die Fixierbolzen und die zugehörigen Distanzelemente jeweils ein- teilig, so ist in vorteilhafter Weise pro Fixierbolzen- und Distanzelementj ustage nur ein einziger Montageschritt nötig. A concentric alignment of the low voltage coil re ¬ tively to ensure 100 to the core sheet pack, sheet-circuit is provided between the first Zugankerblech 140 and the electrical connections 280, a spacer means in the form of two spacer elements 300 and 310th The two Distanzele ¬ elements 300 and 310 may be formed for example by spacer plates or spacers, which preferably consists of a NEM electrically non-conductive material. The spacer elements 300 and 310, for example, made of synthetic material ¬, especially glass fiber reinforced plastic, best ¬ hen. The two spacer elements 300 and 310 effect a minimum distance between the first tie plate 140 and the right in FIGS. 5 and 6 side surface of the core leg 120 and the electrical connection plate 280 of the lower voltage coil 100. The two fixing bolts 200 and 210 each with its associated spacer element 300th or 310 be integrally connected. Preferably, the fixing bolt 200 and the spacer element 300 form a common component and, correspondingly, the fixing bolt 210 and the spacer element 310 form another common component. In case of such Substituted ¬ staltung the fixing bolt and the associated spacer elements are preferably made of the same plastic, insbeson ¬ particular made of the same glass fiber reinforced plastic. If the fixing bolts and the associated spacer elements are each one-piece, advantageously only one single assembly step is required per fixing bolt and spacer element jute.
Selbstverständlich ist es auch möglich, die beiden Distanzelemente 300 und 310 sowie die beiden Fixierbolzen 200 und 210 als separate Bauteile herzustellen. Bei einer solchenOf course, it is also possible to produce the two spacer elements 300 and 310 and the two fixing bolts 200 and 210 as separate components. In such a
Ausgestaltung würde man vorzugsweise die beiden Fixierbolzen 200 und 210 in die zugeordneten Bolzenhalteausnehmungen 220 und 230 im Kernschenkel 120 bzw. im Zugankerblech 140 des Kernschenkels 120 einschieben oder einschlagen und darauf dann die zugeordneten Distanzelemente 300 und 310 aufschie¬ ben. Anschließend kann dann die Unterspannungsspule 100 mit den Einhängausnehmungen 260 und 270 auf dem zweiten Bolzenende 250 der beiden Fixierbolzen 200 und 210 aufgesteckt wer- den, wodurch die Unterspannungsspule 100 auf bzw. an dem Kernblechpaket 130 durch Einhängen fixiert wird. Embodiment, one would preferably insert the two fixing bolts 200 and 210 in the associated Bolzenhalteausnehmungen 220 and 230 in the core leg 120 and in Zugankerblech 140 of the core leg 120 or beat and then aufschie ¬ ben the associated spacers 300 and 310. Subsequently, the undervoltage coil 100 can then be attached to the attachment recesses 260 and 270 on the second bolt end 250 of the two fixing bolts 200 and 210. the, whereby the undervoltage coil 100 is fixed on or on the core plate package 130 by hanging.
Um zu vermeiden, dass die Unterspannungsspule 100 von den beiden Fixierbolzen 200 und 210 unbeabsichtigt ausgehängt werden kann, wird die Unterspannungsspule 100 nach einem Ein¬ hängen vorzugsweise in Richtung der zweiten Seitenfläche 165 des Kernblechpakets 130 (vgl. Figur 4) gezogen. Hierzu können Keilelemente eingesetzt werden, wie sie in den Figuren 3 und 4 mit den Bezugszeichen 400 und 410 gekennzeichnet sind. Die Funktion der Keilelemente 400 und 410 besteht darin, die Un¬ terspannungsspule 100 nach einem Einhängen in die beiden Fixierbolzen 200 und 210 (vgl. Figur 4) nach links bzw. in Richtung zur zweiten Seitenfläche 165 des Kernblechpakets 130 zu ziehen, um so ein Aushängen zu vermeiden. In order to avoid that the low voltage coil 200 and 210 can be unhooked inadvertently 100 of the two fixing bolts, the low voltage coil 100 is pulled by a A ¬ preferably hanging toward the second side surface 165 of the core stack 130 (see FIG. 4). For this purpose, wedge elements can be used, as they are identified in FIGS. 3 and 4 by reference numerals 400 and 410. The function of the wedge elements 400 and 410 is to pull the Un ¬ terspannungsspule 100 after hanging in the two fixing bolts 200 and 210 (see Figure 4) to the left or in the direction of the second side surface 165 of the core lamination stack 130 so as to To avoid hanging out.
Nachfolgend wird anhand der Figuren 3-6 ein Ausführungsbei¬ spiel für ein Montageverfahren erläutert: Zunächst werden die Fixierbolzen 200 und 210 in die Bolzen- halteausnehmungen 220 und 230 des Kernschenkels 120 einge¬ schlagen. Falls die Distanzelemente 300 und 310 nicht eintei¬ lig mit den Fixierbolzen 200 und 210 verbunden sind, so werden sie nachfolgend auf die Fixierbolzen 200 und 210 aufge- schoben. Subsequently, a Ausführungsbei ¬ game for a mounting method will be explained with reference to FIGS 3-6: First, the fixing bolts 200 and 210 into the bolt holding recesses 220 and 230 of the core leg beat ¬ turned 120th If the spacer elements 300 and 310 is not eintei ¬ lig connected with the fixing bolts 200 and 210, they are pushed below listed on the fixing bolt 200 and the 210th
Nachfolgend wird die Unterspannungsspule 100 auf den zugehö¬ rigen Kernschenkel 120 auf und somit in die in den Figuren nicht weiter dargestellte Oberspannungsspule des Transforma- tors eingesetzt. Dies erfolgt zunächst außermittig, um einSubsequently, the low voltage coil 100 is thus used to zugehö ¬ ring core leg 120 and into the not shown further in the figures, high voltage coil of the transformer tors. This is done first off-center to a
Vorbeiführen der Unterspannungsspule 100 an den seitlich herausstehenden Fixierbolzen 200 und 210 zu ermöglichen. Sobald die Einhängausnehmungen 260 und 270, die im innen lie¬ genden elektrischen Anschlussblech 280 der Unterspannungsspule 100 vorgesehen sind, in der Höhe des jeweiligen Fixierbol¬ zens 200 bzw. 210 angelangt sind, wird die Unterspannungsspu- le 100 in den Zeichnungen nach links versetzt bzw. so verschoben, dass die Unterspannungsspule 100 mit den Einhängaus¬ nehmungen 260 und 270 auf die herausstehenden Fixierbolzen 200 und 210 aufgeschoben und somit auf dem Kernschenkel 120 fixiert wird. Die Unterspannungsspule 100 wird damit von den beiden Fixierbolzen 200 und 210 und vom Kernschenkel 120 gehalten . To allow the undervoltage coil 100 to pass past the laterally protruding fixing bolts 200 and 210. Once the Einhängausnehmungen 260 and 270 which are provided in the inner lie ¬ constricting electrical connection plate 280 of the low voltage coil 100 have reached the level of the respective Fixierbol ¬ zen 200 and 210, the under voltage coil is 100 in the drawings offset to the left or So that the lower voltage coil 100 with the Einhängaus ¬ recesses 260 and 270 is pushed onto the protruding fixing bolts 200 and 210 and thus fixed on the core leg 120. The undervoltage coil 100 is thus held by the two fixing bolts 200 and 210 and the core limb 120.
Um zu vermeiden, dass die Unterspannungsspule 100 von den Fi¬ xierbolzen 200 und 210 weggeschoben bzw. aus diesen ausgehakt werden kann, werden auf der anderen Seiten der Unterspannungsspule - und zwar in der Figur 4 links zwischen der Unterspannungsspule 100 und dem Kernschenkel 120 - zwei Keil¬ elemente 400 und 410 eingeführt bzw. eingeschlagen, die die Unterspannungsspule 100 nach links versetzen bzw. nach links ziehen, so dass die in der Figur 4 rechte Seite der Unterspannungsspule 100 nach links auf die Fixierbolzen 200 und 210 gezogen wird. Die Funktion der Keilelemente 400 und 410 besteht also darin, ein Aushaken der Unterspannungsspule zu verhindern . In order to avoid that the low voltage coil 100 200 and 210 pushed away from the Fi ¬ xierbolzen or can be unhooked from these, are on the other side of the low voltage coil - in the Figure 4 left between the low voltage coil 100 and the core leg 120 - two Wedge ¬ elements 400 and 410 introduced or hit, which move the lower voltage coil 100 to the left or pull to the left, so that the right in the figure 4 side of the lower voltage coil 100 is pulled to the left on the fixing bolts 200 and 210. The function of the wedge members 400 and 410 is thus to prevent unhooking of the undervoltage coil.
Die zwei Keilelemente 400 und 410 könnten zu einer außermit¬ tigen Anordnung der Unterspannungsspule 100 führen, wenn nicht die Distanzelemente 300 und 310 zwischen der Unterspan¬ nungsspule 100 und dem Kernschenkel 120 vorgesehen werden. Mit anderen Worten besteht die Funktion der Distanzelemente 300 und 310 also darin, bei einem Verrücken der Unterspannungsspule 100 nach links, was durch die Keilelemente 400 und 410 bewirkt wird, eine zentrische Ausrichtung der Unterspan¬ nungsspule 100 auf dem Kernschenkel 120 zu gewährleisten. The two wedge elements 400 and 410 could result in a außermit ¬ term arrangement of the low voltage coil 100 when not the spacer elements 300 and 310 between the lower clamping ¬ voltage coil 100 and the core leg 120 is provided. In other words, the function of the spacer elements 300 and 310 is thus in the case of a displacement of the lower voltage coil 100 to the left, which by the wedge elements 400 and 410 is effected to ensure a centric alignment of the lower chip ¬ tion coil 100 on the core leg 120.
Die Keilelemente 400 und 410 bestehen vorzugsweise aus Kunst- stoff, beispielsweise glasfaserverstärktem Kunststoff; sie können beispielsweise Stab-, leisten- oder plattenförmig sein. Um ein Einführen in den Zwischenraum bzw. Spalt zwischen Kernschenkel 120 und Unterspannungsspule 100 zu gewähr¬ leisten, ist zumindest die vordere Stirnseite der Keilelemen- te, mit denen sie in den Zwischenraum bzw. Spalt eingeführt werden, vorzugsweise keilförmig. The wedge elements 400 and 410 are preferably made of plastic, for example glass fiber reinforced plastic; they may be, for example, rod, strip or plate-shaped. An insertion in the intermediate space or gap between the core leg 120 and the low voltage coil 100 afford to be granted ¬, at least the front end side of the Keilelemen- te, with which they are introduced into the space or gap, preferably wedge-shaped.
Zum Verkeilen der Unterspannungsspule 100 können die Keilele¬ mente auch mehrteilig sein, auch kann eine Vielzahl an Keil- elementen montiert werden. To wedge the low voltage coil 100 the Keilele ¬ elements may be in multiple parts, also can produce a variety of wedge elements are mounted.
Außerdem kann auf dem in der Figur 4 linken (zweiten) Zugankerblech 160 zusätzlich eine Abstandsplatte aufgebracht wer¬ den, die mit den einzuschlagenden Keilelementen zusammen- wirkt. Beispielsweise können die Keilelemente zwischen einer solchen Abstandsplatte und der Unterspannungsspule 100 einge¬ schlagen werden, um einen Kontakt mit dem Kernschenkel 120 zu vermeiden . In addition, on the left in the figure 4 left (second) Zugankerblech 160 a spacer plate ¬ applied, which cooperates with the wedge elements to be hammered. For example, the wedge elements between such a spacer plate and the low voltage coil 100 can be inserted ¬ propose to avoid contact with the core leg 120th
