Definitions

  • the present invention relates to a shield for receiving at least one is a non-ionizing radiation or a non-ionizing one Field generating object. In particular, it is about the Protection against electromagnetic fields in the area of energy plants.
  • the invention has as its object, a shield for receiving at least one of a non-ionizing radiation or a non-ionizing one Creating field generating object, which is a compliance of the Limits allowed.
  • the invention corresponds to the characterizing features of Claim 1. Further advantageous embodiments are dependent Claims.
  • the inventive shielding is in the range of energy systems, For example, in transformers, a more effective and yet with relatively little constructive and financial effort achievable protection against electromagnetic fields created.
  • Fig. 1 is the example of a transformer shown schematically 1 shows the course of the field lines 2 of an electromagnetic interference field.
  • the area of this transformer 1, the part of a further not shown network station is to shield it.
  • the transformer 1 is arranged in a specially shaped and constructed shield 3. From the basic idea, preferably two are orthogonal Intersecting tube section-like elements 4 and 5 with approximately rectangular Cross section arranged. Seen from above and from below, is by this arrangement of the pipe section-like elements 4 and 5 a cross, more precisely a Swiss cross, formed. The transformer 1 is in the middle of this three-dimensional shield 3, on the bottom of which 6 standing, arranged. It goes without saying that in intersection or overlap area in the bottom 6 and in the ceiling 7 of the two pipe section-like elements 4 and 5 no Wandaufdoppelung the shield 3 must be given. Rather, here is the wall of the Shield 3 built exactly the same as in the other parts.
  • the four corners 8, 9, 10 and 11 of the shield 3 remain open in any case, these preferably being dimensioned so That should at least be right in front of the cooling fins 12 and 13 of the transformer 1 lying area by a strip-shaped wall part 14, 15, 16 and 17 is covered.
  • transformer masses is the wall width 18 of one of these strip-shaped wall parts 14 - 17 preferably about 100 cm.
  • the open construction of the shield 3 also brings a whole series of advantages.
  • the good air circulation is unhindered Cooling the transformer 1.
  • Transformer 1 is for maintenance personnel easily accessible from all four corners 8 - 11, without shielding or trim parts would be dismounted.
  • Fig. 3 the rational shield of several, side by side arranged transformers 1 shown. In fact, it is many times so that in network stations a number of juxtaposed Transformers 1 is present. It is in this case, as based on the Example of two transformers shown, not required respectively to provide a separate shield 3. Rather, a single, Provide extended shielding 19, without intermediate wall between the individual transformers 1, but only with a first, im Cross-section widened, pipe section-like element 20 and a additional pipe section-like element 22 for the second transformer 1.
  • This expanded shield 19 thus has, from the idea, three pipe section-like or optionally three in cross-section U-shaped Elements 20, 21 and 22.
  • FIG. 4 The wall structure of the wall parts 14-17 and the ceiling 7 and possibly the bottom 6 of the shield 3 or 19 is shown in FIG. 4 in several parts.
  • a first wall 24 is provided, preferably consisting of several layers of a ⁇ m metal.
  • This first, inner wall 24, or the material attached closer to the source of interference, must have the highest possible magnetic conductivity.
  • a high permeability, or a high initial magnetization is important.
  • the initial permeability ⁇ 4 is preferably> 1000.
  • a second wall 26 is present, for example made of aluminum or of an aluminum alloy. This second wall 26 must have the highest possible electrical conductivity, preferably Y> 30 m / ⁇ mm 2 .
  • the magnetically conductive layer and the electrically conductive material are electrically isolated from each other.
  • the two walls 24 and 26 are spaced from each other, forming a hollow space 27.
  • This insulating gap is important on the one hand for the efficiency of the shield.
  • the profiles 28 of a support structure can be arranged, which gives the shield 3 and 19, the required static stability.
  • care must be taken to ensure that the insulation between the two walls 24 and 26 is not affected by the supporting structure.
  • the walls 24 and 26 can be bolted to the profiles 28.
  • the edges can also be closed so that the profiles 28 of an assembled shield 3 or 19 are not visible. Overall, this results in not only a very effective and practical, but also a shapely construction.
  • the described shield 3 or 19 can be used not only in transformers 1, for which she is especially designed, but also at others, a non-ionizing radiation or a non-ionizing one Use field generating objects, e.g. for control cabinets or for a low-voltage distribution as well as for cable trays, cable ducts or cable trenches.
  • the shield 19 may be e.g. corresponding the embodiment of FIG. 3 are stretched.
  • the shield 3 or 19 in detail also different than drawn and described previously described.
  • the ceiling 7 in several parts or in other ways partially open to construct, as in the present example the case is.
  • the ceiling 7 or possibly a room only partially covering Partial ceiling can, for example, also from each other Legs of L or C-shaped wall parts 14 - 17 are formed.
  • the ceiling 7 and possibly the bottom 6 instead of cross-shaped be formed rectangular, so that the area of the open Corners 8-11 is covered and is e.g. gives a cube-like body.
  • the wall parts 14 - 17 could also be inclined, up to the formation of a Pyramid.
  • the outside wall 26 could also be multilayered be educated.
  • the wall parts 14 -17 and the ceiling 7 could also do so be attached so that they can be disassembled quickly for maintenance purposes.
