Definitions

  • the invention relates to transformers with an active part in an oil-filled, smooth-walled boiler, the side walls of which are supported by welded-on webs and divided into wall-high fields.
  • Such smooth-walled boilers are usually used in large transformers.
  • radiators are provided on the outside and / or front of the transformer tank, or a recooling device combined in a special structural unit is used for this purpose.
  • the boilers for these large transformers are designed according to strength considerations, with the aim of minimizing the wall thickness of the sheets used for reasons of economy and to reduce the transport weight.
  • a large number of webs are generally provided to stiffen the relatively large side walls of the transformer tank.
  • the invention is based on the object of creating an economical design for the boiler of transformers, which ensures that resonance vibrations of the boiler side walls with the transformer core are avoided and, in addition, that the radiation of the vibrations generated by the transformer core is only emitted via the side walls of the boiler dampened.
  • this object is achieved in a smooth-walled boiler with side walls divided into wall-high fields in that the natural frequency f of the sheet metal wall in each field according to the function is less than twice the network frequency, where S is the sheet thickness in cm, B is the clear field width in cm and k f is in its absolute size from the length-width ratio of the field, from the elastic modulus, from the transverse contraction and from the weight of the material used dependent constant is.
  • the fields have a minimum width of 50 cm and that a sheet metal with a thickness of at least 1.2 cm is used for the side walls of the boiler, at least in the area of wall-high fields.
  • the width of the wall-high fields is twice the width of radiators arranged on the side wall and the side walls are composed of field-wide elements, the vertical edges of which are bent outwards to form the webs, the webs adjacent to one another field-wide elements form a V-shaped cross section.
  • the design of the boiler side walls for transformer boilers according to the invention is very advantageous because, as a result, using thicker walls leads to a reduction in the number of webs required for stiffening and thus enables the construction of transformers whose noise emission is lower than that of transformers in practically no additional cost Standard version.
  • the active part of a transformer is arranged in a cuboid housing with edge lengths of a few meters in a manner not shown.
  • the cuboid housing is laterally closed by side walls 1 and end walls 2.
  • the lower edges of the side walls 1 and the end walls 2 are connected oil-tight to a base plate, not shown.
  • a flange 3 is provided, on which a cover 4 is also oil-tight, but is releasably attached.
  • both the side walls 1 and the end walls 2 are divided into individual fields in terms of vibration technology.
  • the number of Crosspieces 5 are relatively small and at the same time the natural frequency of the sheet metal wall in the individual fields is less than twice the network frequency.
  • FIG. 2 shows a detail of a cross section through a side wall 1 or end wall 2 composed of field-wide elements 6.
  • the vertical edges of these field-wide elements 6 are folded over a vertical line by less than 90 °.
  • the folded edges of adjacent elements 6 thereby each form a cross-sectionally V-shaped web, the outer contact line of which is closed by a weld seam 7.
  • the construction of the side walls 1 and the end walls 2 from elements 6 allows the transformer tank to be constructed in accordance with the modular principle by means of their standardization and contributes to more economical production by a possible reduction in the storage of sheet metal.
