- Fig.lA to 1E there is shown the various stages of mounting a three-phase transformer with dry insulation according to the invention.
- FIG. 1A a low voltage winding 1 has been shown placed on a column 2 of the magnetic circuit of a three-phase transformer shown more fully in FIGS. 1D and 1E.
- a sleeve 3 of polymer resin is molded on the central part of column 2, i.e. outside the end parts 2A and 2B shaped bevel, for the subsequent meeting of the column 2 with yokes for closing the magnetic circuit.
- thermoplastic This is done by injection, or by hot strip compression, if the polymer used is thermoplastic.
- the material used can also be a thermosetting resin. It is important that the material is conductive of heat and this as much as possible. To this end, it may contain an adequate proportion of carbon, for example, which has the additional advantage of also making it weakly conductive of electricity, in accordance with a preferred variant of the invention which will be explained by the following.
- a metallic electrical conductor 5 is wound on the surface of the sleeve, which will form the low voltage winding of the transformer as shown in particular in FIG. 1D and also on the Figures 2,3 and 4.
- This conductor 5 can be in the form of large strips or flat aluminum or copper. It is conventionally wrapped in oiled insulating paper. Each of its ends is extended outside by conventional connection bars 6.
- the low voltage winding thus produced is then encapsulated in a layer 7 of dielectric polymer resin a few millimeters thick, for example 3 mm.
- This resin envelope 7 is produced by hot compression of superimposed sheets of thermoplastic material, which is also thermally conductive in order to promote heat exchange with the surrounding air.
- this resin is also slightly conductive of electricity, which improves the overall safety of the device to be produced, by putting the earth at potential at point 7A represented in FIG. 1A.
- the sleeve 3 although being an intermediate entity which will disappear as such in the completed embodiment shown in Figure 1A, nevertheless fulfills several essential roles.
- the sleeve 3 fulfills a major role of heat exchanger which promotes the cooling of the column 2 or of the winding 5 by conduction of heat through the thermally conductive material of which said sleeve is made.
- projections 8 in the form of longitudinal ribs forming spacers for the high-voltage coil shown in FIG. 1B and which will be placed around the 'low voltage stage of Figure 1A.
- ribs from 3 to 50 mm in height for example, also serve to define between them channels 9 for circulation of a cooling fluid by convection such as air between the low voltage stage and the high voltage stage as can be seen for example in Figure 1C.
- the outer surface of the dielectric polymer resin coating 7 has four ribs 8 distributed at 90 ° relative to each other along the periphery of the coating envelope 7.
- the coating or encapsulation resin envelope 7 preferably has a certain capacity for conducting electricity, in particular when it is formed from a polymer resin charged with electrically conductive particles or with a naturally conductive polymer resin.
- the compression rings 4 are in fact end flanges intended to laterally contain the metal conductor wound 5 in multi-layer turns and are shaped to take account of the helical winding of the latter. It is necessary for the end turns of each layer of the preformed winding of the conductor 5 to bear continuously against these flanges over their entire length. This implies an inward or outward ramp shape of the bearing face of each ring 4 according to the orientation of the winding helix of the turns.
- the low-voltage stage shown in FIG. 1A is of course produced in as many copies as the transformer to be built has phases.
- Figures 1B to 1E schematically show the stages of construction of a three-phase dry transformer.

- a layer 18 On the coating layer 12 is further pressed by hot compression, a layer 18 a few millimeters thick of an electrically conductive thermoplastic resin covering all the surfaces of the high-voltage winding as well as outside than inside of it.
- This resin forming a surface layer 18 (FIG. 2) is charged with carbon particles to make it electrically conductive and it is of the same nature as the insulating polymer forming the coating 12.
- the interfaces with the insulators can be made free of vacuoles.
- the high voltage coil is then finished. It remains to be specified that the thicknesses of insulation on the winding are sufficient to withstand the maximum dielectric stresses that can be applied between the winding and the electrically conductive layer 18 connected to earth, or between the internal connections of the winding and the electrically conductive layer 18 connected to the ground, between the terminals 15 of the winding and the electrically conductive layer 18 connected to the ground.
- the orifices 14 formed around the output conductors 15 are intended to allow the connection of the high voltage coil to the network, or to connect the high voltage coil to other high voltage coils so as to achieve an electrical coupling such as 'It will be described with reference to Figure 1E, and to connect to the high voltage coil, an adjustable connector such as the set of conductors 20 appearing in Figure 1B in a hole 22 of square shape formed in the side strip 16 between the orifices 14 for passage of the connection conductors of the high-voltage winding.
- the high voltage winding 10 is then placed on the low voltage winding 1 as shown in FIG. 1C.
- the low voltage winding 1 mounted on its column 2 is introduced into the high voltage winding 10.
- the ribs 8 present on the periphery of the conductive coating 7 of the low voltage winding allow try to center the high voltage stage on the axis of the magnetic column 2 of the low voltage winding and to provide a channel 9 for cooling by ambient air between the low voltage 1 and high voltage windings 10, the ribs 8 thus forming spacers between the two windings.

- the axis of the transformer windings is preferably close to vertical to improve the cooling of the transformer by natural convection of the ambient air.
- the frame 34 can also be used to reinforce the timing of the windings. This setting is necessary to oppose the electro-dynamic forces exerted on the windings, in particular during network short-circuits.
