Definitions

  • the invention relates to a transformer according to claim 1.
  • the windings of transformers are in operation, especially when short circuits occur, mechanically stressed. Due to dynamic short-circuit forces, loosening can occur of the windings occur, which inevitably destroy the Leads transformer.
  • the object of the invention is therefore to provide a transformer to create the type described above, in which a subsequent Winding compression is possible and then one Loosening of the winding avoided by dynamic short-circuit forces becomes.
  • the transformer according to the invention is by the Features of claim 1 defined.
  • the invention is a controlled pressing possible. Even in the event of a revision, a defined one Pressing can be specified.
  • the spring assembly preloaded and inserted with the preload.
  • Means the set screws can be the predefined pressure on the Winding can be achieved.
  • hydraulic cylinder If the hydraulic cylinder is also installed, it can also for example tightened at any time via a connection to the outside will. The for the operational safety of the transformer required winding pressure is over the remaining life of the transformer.
  • the windings 2 are equipped with hydraulic cylinders 11 which are between the press beam 1 and the winding pressure ring 3 introduced are pressed to the calculated pressure. Subsequently the prestressed spring elements 6 are used.
  • the spring elements 6 are preloaded by means of a fixation 18, the path of the plunger 9 and thus the travel of the Disc springs 8 limited in the socket 7.
  • the set screw 17 is placed on the stamp 9 and the pressure from the Hydraulic cylinders 11 taken.
  • the hydraulic cylinders 11 can get extended.
  • the pulling of the fixation 18 is due to the then a precisely coordinated design of the system is possible.
  • the number of spring elements 6 to be used per winding 2 depends on the total pressing force required in both cases from.
