Definitions
- the invention relates to a holding device for fastening a cast resin transformer winding relative to a transformer core with a support element. Furthermore, the invention relates to a specially designed tie rod and a supporting element corresponding thereto for holding a casting resin transformer winding.
- the windings are permanently fixed relative to an upper and lower yoke of the transformer core by means of suitable fixing elements.
- This is accomplished in particular by means of plastic support components, usually in the form of elongated blocks.
- DE 201 05 608 U1 describes a supporting device for an electrical component in the form of a coil.
- a cuboid elongated block is wedged with a corresponding component of the shape, so that a fixing and centering of the winding takes place relative to the transformer core.
- a fixing device for an electrical winding according to DE 10 2005 058 0119 B4 is known, integrated in the fixing devices within a winding and allows direct screwing of the winding with the lower yoke of the transformer core. As a result, a permanent fixation of the winding is ensured relative to the transformer core.
- a disadvantage of the solutions in the prior art is that the corresponding components partially affect a circulation of the surrounding medium in the bottom region of the winding and it comes to relatively short creepage paths due to the direct connection between the windings and or the transformer core.
- the object of the present invention is therefore to avoid the disadvantages of the prior art and to provide a holding device for fixing a cast-resin transformer winding which is easy to assemble and at the same time does not impair circulation of air between the inner wall of the winding and the transformer core ,
- a tie rod which contains a receiving element for fastening a correspondingly configured supporting element.
- the tie rod is designed so that the receiving element has a central web and a fastening element, wherein the support element is connectable to the fastening element.
- a fastener connectable to the support member By providing a fastener connectable to the support member, a modular construction for securing the winding in accordance with the present invention is provided.
- only a corresponding fastening element has to be configured in such a way that it can be correspondingly connected to the supporting element.
- the receiving element can be configured differently in so far.
- the receiving element is weldable to the tie rod.
- the tie rod has a recess, so that the tie rod can be screwed to the transformer bar.
- a secure attachment not only of the tie rod on the transformer core, but by means of the receiving element and the korres- ponding support also ensures a secure and permanent fixation of the winding by means of the support element.
- the object is likewise achieved by a supporting element for holding a winding, in that the supporting element can be connected to a receiving element which can be attached to a tie rod and thus ensures that the winding is held.
- the support element has an elastic receiving surface for holding the G manharztransformatoren- winding.
- a receiving surface for holding the G manharztransformatoren winding at the top of the support element resulting forces of the windings can be intercepted.
- the support element has a recess for receiving an insulating cylinder.
- the insulating cylinder conventionally arranged around a winding can be replaced by means of a corresponding
- Insulating cylinder can be easily and securely fixed by means of the support element.
- the support element has a detent on the receiving surface for fastening the cast-resin transformer winding and / or in the recess for fastening the insulating cylinder.
- a clamping connection similar to a vice, by tightening the screw, the distance within the recess of the support element or to the receiving surface to be locked in each case Component in the form of cast resin transformer winding or the insulating cylinder are locked quickly and easily.
- the support element advantageously comprises an electrically insulating material so that partial discharges are avoided and sufficient insulation in this region of the cast-resin transformer is ensured.
- the object is likewise achieved by a holding device for fastening a cast-resin transformer winding in such a way that the support element is connected to a receiving element attached to a tie rod.
- the holding device consists of two tie rods, each having a receiving element on the front and back of a leg of the transformer core, wherein the cast resin transformers winding is fixed by two corresponding to the receiving elements supporting elements.
- Breakpoints are fixed in the lower region, so that in this way a high stability of the holder of the windings is ensured.
- the holding device is provided that are mounted above the G manharztransformatoren- winding spacers for mounting an insulating cylinder relative to the cast-resin transformer winding.
- appropriately designed spacers are positioned in the upper region of the cast resin transformer winding in such a way that contact or displacement of the insulating cylinder ders is excluded relative to the cast resin transformer winding.
- FIG. 1 shows a tie rod according to the invention with a receiving element.
- Fig. 2 shows an inventive support with a
- FIG. 3 shows a detailed view of a tie rod attached to a transformer core with a receiving element and support element
- Fig. 5 is a detail view of the upper yoke portion with a tie rod on the transformer core and two spacers.
- Fig. 1 shows a tie rod 1 according to the invention with a receiving element 2, which consists of a web 3 and a fastening element 4. Furthermore, the tie rod 1 has a bore 5, through which a screw can be passed and connected to the transformer core.
- the web 3 of the receiving element 2 is attached to the tie rod 1. welded.
- Other connection methods, such as screwing or gluing, are also included within the meaning of the present invention.
- the fastening element 4 is in the example shown in FIG. 1 on the web 3 of the receiving element 2 plugged.
- FIG. 2 shows the support element 6, which has a bearing surface 7 and a recess 8.
- the cast-resin transformer winding 12 is (not shown) can be placed on the support surface 7.
- a lock 9 the inner spacing of the recess 8 can be reduced.
- the support element 6 can be firmly connected to the receiving element 2 with a corresponding lock 9.
- a detent 9 can be used to firmly connect the cast resin transformer winding 12 to the bearing surface 7.
- FIG. 3 shows a partial view of the transformer core 15, in which the tie rod 1 is integrated.
- the support element 6 serves to hold the cast-resin transformer winding 12 and the insulating cylinder 10.
- the tie-rod 1 is likewise fastened in the transformer core 15 and in the lower yoke 14.
- FIG. 3 by defining the distance between the recess 8 and the support surface 7, the distance between the cast-resin transformer winding 12 and the insulating cylinder 10 can be precisely determined.
- FIG. 4 shows a spacer IIa, with which the distance to the insulating cylinder 10 can be set in the upper region of the cast-resin transformer winding 12.
- FIG. 5 shows a spacer IIa, with which the distance to the insulating cylinder 10 can be set in the upper region of the cast-resin transformer winding 12.
