Definitions

  • This invention relates to a transformer of an electric / electric device.
  • This transformer is a single winding on the primary side] connected by a star connection ⁇ or j filter connection and passed through a magnetic circuit so that the secondary winding is wound in the opposite direction to each other.
  • ⁇ ⁇ ⁇ Potentials on each primary side Prevent the generation of line voltage versus earth voltage by eliminating the effects on other circuits.
  • Figure 1 shows an electrical circuit diagram. An air circuit is shown between the corresponding coils. This figure shows ⁇ when the primary control is star-connected.
  • Figure 2 shows an example of a construction drawing.
  • Transmission system Distribution system Should be used in electrical circuits to minimize power accidents and prevent electrical pollution

Abstract

Transformateur pour un appareil électrique. Dans la pratique, la tension de ligne dans un circuit à courant alternatif triphasé est élevée par rapport à la tension de la masse en utilisant un circuit de retour à la masse. Le transformateur en question utilise par contre trois bobines individuelles du côté primaire selon un agencement en étoile ou en delta, et deux bobines individuelles pour chaque phase du côté secondaire, agencées dans le sens de rotation des aiguilles d'une montre et dans le sens inverse de rotation des aiguilles d'une montre, annulant ainsi la tension du secondaire et éliminant la tension du primaire.
