Definitions

the invention relates to an electrical winding arrangement with at least one electrical winding having at least two supporting parts is supported against a holding arrangement.
Such an electrical winding arrangement is in the GEAFOL cast-resin transformer from Siemens AG / Trafo-Union obviously pertaintemp; This transformer is also in the Brochure "GEAFOL cast-resin transformers - top technology pictured in one piece "of the Trafo Union Transformer is three-phase and has three winding combinations each with two coaxial with each other arranged windings, each having a core leg surrounded by a three-legged core of the transformer. The windings are on each of their faces with at least a support member against a holding device forming frame supported, which with the core legs connected to the three-legged core connecting core yokes is.
Each support part has an inelastic support element and another resilient support member adjacent thereto on, wherein the inelastic support member on the support assembly and the other resilient support on the front side the winding is applied.
the support elements are all heat resistant formed according to class F of DIN 532, Part 6.
the object of the invention is an electrical winding arrangement specify the type mentioned, which comparatively requires little effort.
the object is in an electrical winding arrangement of the type mentioned in the present invention achieved by that the support parts formed differently heat resistant are and arranged such that the heat-resistant support member in a relatively warm region of the winding arrangement during operation is arranged and that is less heat resistant Supporting part at a relatively cool region of the winding assembly located.
the electrical winding arrangement not in all areas the same temperature and the support parts accordingly Not all exposed to a same high temperature are so that not all support parts are the same, for the highest possible occurring thermal load of Support parts must have designed heat resistance. Rather, the support parts that are relatively in operation cool area of the winding arrangement are arranged less heat resistant than the support parts that are in operation are relatively warm area of the winding arrangement. There the less heat-resistant support parts are less expensive, also requires the winding arrangement according to the invention only a small effort.
the support parts can each have a heat resistance, specifically with regard to the applied thermal Load is adapted to the respective installation location.
Prefers The heat resistant support member has a thermal resistance class F according to DIN 532, part 6 and the less heat resistant Support part a thermal strength class B according to DIN 532, part 6.
the winding is cylindrical and standing and arranged at its upper end face with the heat-resistant support part and at its lower end side with the less heat-resistant support member against the support assembly supported.
the standing arrangement along the winding forming temperature gradient between the lower and the strongly noticeable on the upper front side; in the area of the upper At the front side, significantly higher temperatures occur than in the Area of the lower front side. Accordingly, the heat resistance chosen the two support parts.
the support parts can be made in one piece and from a single material be trained, but they can also be arbitrary be composed of several individual parts, provided each of the Items that have the required heat resistance.
the inelastic support element with hard paper, Hard tissue, wood and / or thermoset formed.
This are particularly suitable materials for the inelastic support element.
thermoset Supporting the thermoset according to the required Heat resistance can be selected.
the elastic support element with a Elastomer formed.
These materials are due to their resilient properties particularly good for the formation of the resilient Ab rangelements suitable.
the resilient support element of the heat-stronger support part with a silicone rubber educated. Silicone rubber is one accordingly heat-resistant material.
the resilient support member of the less heat-resistant Support part formed with neoprene is one inexpensive and resilient and therefore for the less heat resistant support well suitable material.
the figure shows a three-phase transformer 1 with a three-leg transformer core 2 and three winding combinations 3 to 5, each having a core leg 6, 7 and 8 respectively surround.
the structure of the winding combinations 3, 4 and 5 is each similar and is shown by the cut Winding combination 5 explained.
the winding combination 5 has a first outer winding 9 which has a inner winding 10, leaving a ring channel 29 coaxial surrounds.
the annular channel 29 is by means of a cooling cylinder 30 divided into two sub-channels 29A and 29B, with the cooling air can be flowed through.
the winding combinations 3 and 4 are only the respective outer winding 9 corresponding outer windings 11 and 12 visible.
FIG Form of a frame 21 For holding all Windings 9, 10, 11 and 12 is a holding arrangement in FIG Form of a frame 21 provided, the frame carrier 22, 23, 24, 25.
the frame rails 22 and 23 are connected to the upper, the core legs 6, 7 and 8 are magnetic with each other connecting core yoke 26 connected.
the frame supports 24 and 25 are connected to the corresponding lower core yoke 26A.
the windings 9 to 12th and the inner winding 10 corresponding inner windings the winding combinations 3 and 4 (due to the perspective Representation concealed) supported to the holder.
the support parts 13, 14 and 16 for supporting the winding 11 and the winding 9 corresponding inner winding of the winding combination serve 3, the support members 17 and 18, the the support of the winding 12 and corresponding to the winding 10 inner winding of the winding combination 4 serve and the support members 19, 20 and 21 for supporting the Windings 9 and 10.
the support elements 13, 14, 17, 19 and 20 are formed of a heat-resistant material, as the support members 16, 18 and 21st
the winding combinations heat up 3 to 5 due to their electrical losses, these are in their closer to the frame rails 22 and 23 out areas are warming up more than in their own the frame members 24 and 25 lying areas.
These different Heat distribution in the winding combinations 3 to 5 is mainly due to the fact that their upper, to the frame members 21 and 22 lying down areas, worse with the through the annular channel 29 and by the corresponding ring channels of the winding combinations 3 and 4 flowing cooling air to be cooled.
the annular channel 29 and the corresponding ring channels of the winding combinations. 3 and FIG. 4 shows a bottom-up direction Flow of cooling air.
the experienced Support elements 13 and 14 a stronger thermal load as the support element 16, so that the support elements 13 and 14 are formed heat-resistant than the support members 16th
the support element 16 does not have to be this way be formed heat-resistant as the support elements 13 and 14th
the support elements 13 and 14 have in particular a thermal Strength of class F according to DIN 532, part 6 and the less heat-resistant support member 16 has a thermal resistance Class B of the same DIN standard.
the support members 17, 19 and 20 are heat-resistant formed as the support members 18 and 21st
the support part 13 with an inelastic support element 15 and an adjoining resilient Supported 15a formed.
the inelastic support element 15 rests against the frame carrier 22 and the resilient Supporting element 15a is located on the end face 28 of Winding 11 at.
the winding 11 is resilient supported the frame 21 and different thermal expansions the winding 11 are by means of the resilient support element 15a recorded so that the winding A always is fixed.
the support member 16 is also with an inelastic Supporting element 16b and an elastic support element 16a trained.
inelastic support member 15 or 16b is for example hard paper, hard tissue, wood and / or a correspondingly heat-resistant thermoset; equally can a ceramic material can be used for this.
elastic support member 15a of the heat-resistant support member 13 is an elastomer, in particular a silicone rubber.
the resilient support member 16a of the less heat resistant support member 16 may be formed with neoprene, for example be.
the support parts 17, 19 and 20 are similar to the support part 13 also with a corresponding inelastic and a corresponding resilient support member formed;
the support members 18 and 21 are the same Supporting member 16 with a corresponding inelastic and a executed according to resilient support member.
