Definitions

  • Figure 6 - represents a front view of a three-phase submersible dry transformer, highlighting the electrical insulation sheet, according to the object of the present invention.
  • Figure 1 shows a floor view of the submersible dry transformer, comprised by an insulation system, according to the teachings of the present invention.
  • the low voltage windings 2, also called internal windings, and the high voltage windings 3, called external windings, are electrically insulated from a solid material, being also possible to note the existence of a core win- dow 20 defined as a space between two core columns 1.2, 1.3.
  • the core window 20 is defined as the space formed by the central column, or leg of the core 1.2, and the side columns, or legs of the core 1.3 at the height of the core legs 1.2 e 1.3.
  • Such channels 15 allow the passage of the low voltage 2 and high voltage windings 3 through the structure of the insulation sheet 4.
  • the electrical insulation wall 4, accord- ing to the teachings of the present invention is preferably sealed to the low voltage and high voltage windings 2,3 using silicone material.
  • other methods can be used in order to seal the windings on the insulation wall 4, as proposed.
  • the use of the electrical insulation sheet 4, according to the object of the present invention allows the transformer to operate at powers quite higher than those available in the state of the art today.
  • An additional advantage of the distribution transformer of the present invention refers to the fact that it is free from insulating oils, which could contaminate the environment, such as the water table should leakage occur, during the transportation or during the operation of the transformer.
  • the underground chambers for the installation of the submersible transformers proposed in the invention herein can be executed in a more economic and simpler manner, once they do not require a system for oil containment, in case of leakage or explosion.
