Definitions
- the present invention relates to a shunt inductor.
- Such coils are used to compensate for the capacitive reactive power of long lines of high voltage electrical energy.
- a known type of such a shunt inductor comprises a magnetic core constituted by a stack of laminated iron sections separated from each other by airgaps made of non-magnetic material, an electrical winding surrounding said core and a magnetic mantle for closing. of magnetic flux.
- a magnetic coat is a laminated magnetic circuit comprising two legs parallel to the axis of the coil joined by two yokes, the core being between the midpoints of the two yokes.
- Another known solution consists in placing a tie rod in the central hole of the core. From the point of view of saving space and saving copper this solution is ideal, on the other hand there is a heating of the fixing system because of the losses by eddy current in the drawing.
- the present invention therefore relates to an electric shunt inductor for an electric power transmission line comprising a magnetic core around which an electric winding is placed, and a magnetic mantle for closing the magnetic flux comprising two branches parallel to the axis of the winding joined by two yokes, said magnetic core comprising a central hole and being constituted by a stack of sections of iron separated from each other by air gaps made of non-magnetic material, characterized in that the yokes are clamped against the magnetic core and said branches by means of several tie rods of non-magnetic material passing through said central hole and passing through said cylinder heads, spacer washers being placed regularly along the tie rods so as to prevent their vibration.
- tie rods there are seven tie rods, one of which is located in the axis of the central hole of the core and the other six regularly distributed around.
- a piece in the form of a bowl whose bottom is pierced with seven holes nuts screwed on the tie rods preventing the removal of said piece, which is threaded on its outer periphery and receives a nut bearing on washers having an axial elasticity and exerting a bearing force on the upper cylinder head.
- said nut bearing on the washers is divided into two superimposed parts which can be screwed separately onto said cup-shaped part, the upper part of said nut having a bottom at its upper part, pierced with a tapped hole.
- FIG. 3 we see a small part of the magnetic core of a shunt inductor.
- a core consists of a stack of laminated iron sections, two sections of which: 1 and 2 are shown in FIG. 3.
- the sections are cylindrical and have a central hole 3.
- the sections are separated from each other by air gaps 4 in non-magnetic material.
- At the top and at the base of the magnetic core are located an upper yoke and a lower yoke joined at their ends by vertical branches, these yokes and these vertical branches are not shown in FIG. 3.
- tie rods 5, 6, 7, 8, 9, 10 and 11 are used, of which only three are visible in FIGS. 1 and 3.
- the tie rod 6 is placed in the axis of the core and the others distributed regularly around.
- Figure 1 shows the device for exercising and maintaining traction in the tie rods.
- the part located to the left of the axis 26 of the winding is shown before tightening and the part located to the right of the axis 26 is shown after tightening.
- a part 12 in the form of a bowl comprising an external cylindrical wall threaded.
- Nuts 13 serve to retain the part 12 on the tie rods.
- a nut 14 in two independent parts 14A and 14B is screwed onto the external wall of the bowl-shaped part 12, and the lower end of the part 14B of the nut is supported on washers 15 which have a certain axial elasticity .
- the washers 15 rest on the upper yoke, not shown, by means of a support distribution plate 16 and of insulation 17.
- spacer washers 24 are placed on the tie rods: three washers are placed at the level of each section of iron. For example, at section 2 (fig.3), place a washer on tie rods 7, 8 and 10 as shown in Figure 2. On the Figure 3 we see the washer 24 on the tie rod 7 and part of the washer located on the tie rod 8 placed behind the tie rods 5 and 6. At the next section, for example section 1, the washers will be placed on the tie rods 5 , 9 and 11. These washers are supported on an insulating cylinder 25 placed inside the central hole of each section.
- the clamping device according to the invention thus occupies very little space and the heating of the tie rods is very low. Furthermore, the number of tie rods equal to seven is that which allows the best filling of the hole for a given diameter and it also allows a very practical setting of the tie rods by means of three washers offset alternately at the level of the successive sections.
