il est connu de disposer une bobine de réactance, montée en série avec l'enroulement du secondaire, avec le transformateur sur un noyau en fer à trois branches et, comme dans
le cas d'un transformateur biphasé, de disposer les enroulements du transformateur et l'enroulement de la bobine
de réactance chacun-.- sur un noyau, tandis que le troisième noyau, sans enroulement, sert pour le retour du flux magné-

Dans l'exemple de réalisation, l'entrefer est constitué par un paquet de tôles 6 ovale, pouvant tourner, qui se trouve entre les deux parties de la branche 5. Suivant la position du paquet de tôles, l'entrefer augmente ou diminue. L'enroulement secondaire est fait de façon telle que,

Transformer with adjustable dispersion reactance, especially for arc welding.
We know different transformers with adjustable dispersion reactance in which we aim. obtain an assembly as compact as possible of the transforma-

it is known to have a reactance coil, mounted in series with the winding of the secondary, with the transformer on a three-branched iron core and, as in
in the case of a two-phase transformer, to arrange the windings of the transformer and the winding of the coil

che 3 serves as a common return for the magnetic flux. The dispersion reactance is adjusted by modifying
<EMI ID = 6.1>
In order to have a large adjustment area, we can still,

coils which are wound only around branch 5 and others which are wound only around branch 4.
In the exemplary embodiment, the air gap is formed by a packet of oval sheets 6, which can rotate, which is located between the two parts of the branch 5. Depending on the position of the pack of sheets, the air gap increases or decreases. The secondary winding is made in such a way that,
