Abstract
(EN)
The present invention relates to a transformer. The transformer according to the present invention comprises: an enclosure; a wiring unit and an iron core unit provided inside the enclosure; an insulating fluid provided inside the enclosure; and a reinforcing unit, which is provided outside the enclosure and encompasses the enclosure, wherein the reinforcing unit is made of a second material which is a material having a yield strength higher than the yield strength of a first material which is a material for forming the enclosure, so as to press the enclosure and prevent expansion of the enclosure.
(FR)
La présente invention porte sur un transformateur. Le transformateur selon la présente invention comprend : une enceinte; une unité de câblage et une unité de noyau de fer disposée à l'intérieur de l'enceinte; un fluide isolant disposé à l'intérieur de l'enceinte; et une unité de renforcement, qui est disposée à l'extérieur de l'enceinte et englobe l'enceinte, l'unité de renforcement étant constituée d'un second matériau qui est un matériau ayant une limite d'élasticité supérieure à la limite d'élasticité d'un premier matériau qui est un matériau pour former l'enceinte, de façon à presser l'enceinte et empêcher la dilatation de l'enceinte.
