Definitions

  • the invention relates to a power transformer in dry construction with a preferably formed as a winding core core made of amorphous material which is sensitive to mechanical stresses, with at least one surrounding the core, at least one primary winding and secondary winding formed winding body and at least one holding device.
  • Transformers are used for power transmission in power supply by voltage adjustment from a first voltage level to a second one.
  • power transformers in dry construction so-called dry-type transformers, are increasingly being used.
  • the structure of a power transformer in dry construction is very similar to that of the power transformer with oil filling, as well as power transformer in dry construction, the respective winding body are applied to cores made of ferromagnetic material, which are connected at both ends with yokes and form a magnetic circuit.
  • Ohmic losses occur in the windings of a loaded transformer due to the winding currents and eddy currents in the conductor material. These ohmic losses are superimposed by no-load losses and possibly short-circuit losses and hysteresis losses.
  • the no-load losses are mainly determined by the induction and nature of the core and are approximately independent of the operating temperature of the transformer.
  • the short-circuit losses are temperature-dependent and increase at constant load with the temperature or the resistivity of the conductor material.
  • core materials with a very narrow hysteresis loop are used.
  • amorphous core material is used in place of grain-oriented core material in recent times.
  • amorphous materials require new constructions and processing because the amorphous material is largely pressure-sensitive so that core losses can be enhanced.
  • the invention provides that the core is kept suspended from amorphous material of the holding device, wherein the holding device for fixing the at least one primary winding and secondary winding is used and for this purpose acts on the at least one winding body respectively at its end faces.
  • the amorphous core is made in each case as a winding tape core of strip material made of amorphous material.
  • the metal coils prepared for use as cores are held in shape by means of tear-resistant tape, in that the tear-resistant tape is repeatedly looped around the sheet stack at a distance from one another, so that the sheet metal coils are held together.
  • the winding cores thus formed preferably have a rectangular plan, that is, they each occupy a rectangular area.
  • embodiments with an oval or circular floor plan are also within the scope of the invention.
  • the transformer according to the invention is designed as a three-phase transformer and has three juxtaposed cores, each of which is comprised of a winding or bobbin.
  • At least two winding cores are arranged side by side with their longitudinal legs and their mechanical connection by means of band material made of amorphous material in the winding plane are wrapped, all legs have the same winding cross-section, that is, the same thickness and width.
  • At least two, but preferably four, of the previously described winding cores are placed with their longitudinal limbs against one another.
  • This arrangement thus formed is then wrapped by means of band material of amorphous material, so that result as a result of this wrapping a total of five legs with the same winding cross-section.
  • the transformer is characterized in that the holding device is formed of at least two clamping elements, which are in operative connection with each other and are arranged on each end face of a winding body. It is provided that the support structure is designed so that mechanical stresses that arise during the fixation of the winding body, are initiated only in the support structure and in the winding body, so that the covered by the winding bodies cores in the support structure, although guided but not braced , so exposed to mechanical stresses are.
  • each core is cylindrical in shape of amorphous material in layer construction with at least two legs and a one-piece molded yoke.
  • the clamping elements of the support structure may consist of ferromagnetic material and at the same time serve as a yoke.
  • each core is magnetically connected to the clamping elements of the holding device.
  • each core end is in each case encompassed on two opposite sides of the clamping elements without pressure, wherein to avoid a compressive load of the core due to a clamping of the core and the resulting mechanical stress, the clamping elements by means firmly connected to the clamping elements spacer exactly Distance to the respective core are kept.
  • the respective core is in this case introduced at the intended location with one end in the space between the clamping elements and held by a likewise firmly connected to the clamping elements support plate, so that, for example, in a three-phase transformer designed as a transformer according to the invention three cores columnar next to each other at the lower yoke serving lower holding device, wherein they optionally engage in the space defined by the two clamping elements gap while avoiding mechanical stresses.
  • the retaining construction consists of non-ferromagnetic material, in particular of fiber-reinforced plastics.
  • the holding structure is not part of the magnetic field circuit in this case, the entire arrangement has a significantly reduced weight compared to a full-metal design.
  • each core is provided at its end faces with a pad of insulating material.
  • This edition serves both as electrical insulation and on the other hand as a means of shock absorption for the relevant core.
  • this edition of an insulating material such as plastic, in particular glass fiber reinforced plastic or silicone rubber.
  • carriers are provided at the front ends of each yoke, which interconnect the yokes, that is, the lower yoke with the upper yoke. These carriers are preferably guided along the outer longitudinal sides of the core or cores and encompassed by the relevant respective winding body, that is, the carriers are guided in the interior of the winding body parallel to the respective core and connected to the opposite yoke.
  • tie rods can be provided which press the yokes formed from the clamping elements against the winding body, wherein the cores are each unimpaired.
  • the invention provides, instead of a hitherto conventional core press construction, in which the attachment of the coil or winding body is effected by pressing against the core, to use a coil press construction.
  • the winding body are held by a support structure independent of the core.
  • the core is only placed or suspended on designated plates of the support structure.
  • this novel transformer namely a transformer having a core composed of layered strips of amorphous material , which is sensitive to mechanical stresses, with at least one surrounding the core, at least one primary winding and a secondary winding formed winding body and specify at least one holding device.
  • the short legs of the winding rings each form the magnetic yokes.
  • the short legs of the winding rings instead of the rectangular shape for the cross section of the individual winding rings and oval or circular cross-sections can be used.
  • the transformer core is formed from a total of four coils with juxtaposed longitudinal limbs, which are mechanically connected to one another, so that in this way a 5-limb core is produced.
  • the mechanical connection as previously indicated for the dreischkeligen core, preferably effected by the single cores are wrapped in its winding plane with tape material and so the composite of the individual cores is made into a 5-leg core.

  • the flanges have a different width and in such a way that the flanges 28 located on the side of the winding body 12 are narrower than those on the side facing away from the winding bodies 12, which are about twice as wide.
  • this design proves to be advantageous because with the wider flanges 28 a correspondingly larger footprint and thus a higher stability is ensured.
  • Each of the winding bodies 12 facing flanges 28 of the clamping elements 25 are used to attach the winding body 12 and thus to force during clamping of the yokes 22, 24.
