Title
(EN) THREE-PHASE TRANSFORMER
(FR) TRANSFORMATEUR TRIPHASE
Abstract
(EN)
A three-phase transformer comprises three closed magnetic circuits (1, 2, 3), primary and secondary windings consisting of electrically interconnected parts (6, 7) and (10, 11), as well as primary windings (4, 5) and secondary windings (8, 9). The parts (10, 11) and the parts (6, 7) are located on the corresponding sections (12, 13) of the magnetic circuits (1, 3). The sections (15, 16) of the magnetic circuit (2) are neighbouring, respectively, upon sections (14, 17) of the magnetic circuits (1, 3) and carry the primary windings (4, 5) and the secondary windings (8, 9). Since less winding wire is used for making the transformer and because demagnetizing influences from the secondary windings (8, 9) are avoided, the weight and dimensions of the transformer and the electic energy losses are decreased and the design of the transformer is simplified.

Un transformateur triphasé comprend trois circuits magnétiques fermés (1, 2, 3), des enroulements primaires et secondaires composés de parties interconnectées électriquement (6, 7) et (10, 11), ainsi que des enroulements primaires (4, 5) et des envoulements secondaires (8, 9). Les parties (10, 11) ainsi que les parties (6, 7) sont situées sur les sections correspondantes (12, 13) des circuits magnétiques (1, 3). Les sections (15, 16) du circuit magnétique (2) sont voisines, respectivement, sous les sections (14, 17) des circuits magnétiques (1, 3), et portent les enroulements primaires (4, 5) ainsi que les enroulements secondaires (8, 9). Puis qu'on utilise moins de câble d'enroulement pour fabriquer ledit transformateur et comme on peut éviter les influences de démagnétisation provenant des enroulements secondaires (8, 9), il est possible de réduire le poid et les dimensions dudit transformateur ainsi que les pertes en énergie électrique, et de simplifier la conception dudit transformateur.
