Problems solved by technology

[0005] The solution in the prior art has the disadvantage that the corresponding components partly hinder the circulation of the ambient medium in the bottom area of ​​the winding and lead to short leakage paths due to the direct connection between the winding and the transformer core

Embodiment Construction

[0023] figure 1 A mast 1 according to the invention is shown with a receiving element 2 consisting of a web 3 and a fastening element 4 . Furthermore, the pole 1 has holes 5 through which bolts can pass and be connected to the transformer core. The web 3 of the receiving element 2 is welded to the pole 1 in the example shown. Other methods of connection, such as screwing or bonding, are also within the scope of the present invention. Fixing element 4 in figure 1 In the example shown, it can be plugged onto the web 3 of the receiving element 2 .

[0024] figure 2 A support element 6 is shown, which has a bearing surface 7 and a recess 8 . The cast resin transformer winding 12 can be arranged on the support surface 7 (not shown). The inner spacing of the recess 8 can be reduced by means of the locking element 9 . At the same time, the supporting element 6 can be fixedly connected to the receiving element 2 via the corresponding locking piece 9 . Furthermore, locking ele...

Abstract

The invention relates to a holding device for fastening a cast resin transformer winding relative to a transformer core having a support element and a receiving element attached to a tie rod. By fastening the support element to the receiving element attached to the tie rod, a cast resin transformer winding can be fixed rigidly and precisely centered relative to a transformer core. By attaching the receiving element directly on the tie rod, circulation in the lower region of the cast resin transformer winding or of an insulating cylinder also attached to the support element is ensured and thereby the thermal properties of a cast resin transformer winding produced in this way are improved. Furthermore a modular and thus simple design of the cast resin transformer is possible due to the possibility of connecting the receiving element to the tie rod by way of the support element.

Description

technical field [0001] The invention relates to a holding device for fixing a winding of a cast resin transformer relative to a transformer core, said holding device having a support element. Furthermore, the invention relates to a specially constructed pole and a corresponding supporting element for holding a winding of a cast-resin transformer. Background technique [0002] In the manufacture of cast resin transformers there is often the difficulty that the winding has to be fixed relative to the transformer core extending inside the winding. Furthermore, external influences and forces, for example during transport, must not cause changes in the position of the winding relative to the transformer core. [0003] For these reasons, the windings are permanently fixed relative to the upper and lower yokes of the transformer core by means of suitable fixing elements. This fastening takes place in particular by means of support parts made of plastic, usually in the form of elo...
