Claims (2)

1. Enroulement à conducteurs triples pour un transformateur de four composé d'un transformateur principal et d'un transformateur additionnel, enroulement qui est disposé sur le côté secondaire et présente des bobines (5, 6) qui entourent les deux branches des noyaux ferreux (1, 2) du transformateur principal et du transformateur additionnel, par deux barres de liaison parallèles (12 à 15, 19 à 24) situées entre les deux branches, caractérisé par le fait que les barres de liaison (12, 13, 14, 15, 19, 20, 21, 22, 23, 24) d'une bobine (5, 6) s'étendent à une distance normale choisie (25) d'un axe longitudinal (16), de préférence parallèlement à cet axe, qui joint les centres (17, 18) des deux branches ferreuses (1, 2) du transformateur principal et du transformateur additionnel, par le fait que d'autres bobines (5, 6) sont disposées retournées de 180° autour de l'axe longitudinal (16), la distance normale (25) entre les barres de liaison (12, 13, 14, 15, 19, 20, 21, 22, 23, 24) des différentes bobines (5, 6) et l'axe longitudinal (16) se présentant en alternance à gauche et à droite de cet axe, par le fait qu'une plaque de matière isolante (26) dont l'épaisseur est égale au double de ladite distance normale (25), est disposée verticalement entre les barres de liaison intérieures (12, 15, 19, 21, 23), et par le fait que d'autres plaques de matière isolante (32, 33) sont prévues respectivement contre les surfaces extérieures verticales (27, 28, 29, 30, 31) des barres de liaison (13, 14, 20, 22, 24) et assemblées par des liaisons démontables à la plaque de matière isolante (26) placée entre les barres de liaison intérieures (12, 15, 19, 21, 23).
2. Enroulement à conducteurs triples selon la revendication 1, caractérisé par le fait que la plaque de matière isolante (26) située entre les barres de liaison intérieures (12, 15, 19, 21, 23) présente des trous filetés (35), au-dessus et au-dessous des surfaces de portée (36, 37, 38, 39, 40) de ces barres de liaison (12, 15, 19, 21, 23) et par le fait que des vis (41), de préférence isolées ou isolantes et non magnétiques, qui sont vissées dans les trous filetés (35), sont enfilées de l'extérieur des plaques de matière isolante (32, 33) appliquées contre les surfaces extérieures verticales (27, 28, 29, 30, 31 ) des barres de liaison (13,14, 20, 22, 24), à travers les trous (34).
