Title
(EN) CONTAINING TANK OF AN OIL IMMERSED POWER TRANSFORMER
(FR) CUVE POUR TRANSFORMATEUR DE PUISSANCE IMMERGE DANS L'HUILE
Abstract
(EN)
The subject of the invention is the containing tank of an oil immersed power transformer intended for use especially in large capacity power transformers. According to the invention, the containing tank of an oil immersed power transformer is a metal box to which, on its external circumference, acoustic screens (7) or (14) are attached. The longitudinal edges of the acoustic screens (7) or (14) are attached to the side walls (2) or (11) of the box. The lower and upper edges of the acoustic screens (7) are attached to the lower (4) or upper (5) flange of the box (1) respectively. The side edges of the acoustic screens (14) are suitably attached to the vertical brackets (13).

L'invention concerne une cuve destinée à contenir un transformateur de puissance immergé dans l'huile, cette cuve étant destiné en particulier à des transformateurs de grande dimension. Cette cuve est constituée d'une boîte métallique sur le pourtour extérieur de laquelle sont montés des écrans (7 ou 14) antibruit. Les bords longitudinaux des écrans (7 ou 14) antibruit sont fixés sur les parois (2 ou 11) latérales de la boîte. Les bords supérieur et inférieur des écrans (7) antibruit sont fixés respectivement sur le rebord inférieur (4) ou supérieur (5) de la boîte. Les bords latéraux des écrans (14) antibruit sont fixés de manière adéquate sur des supports (13) verticaux.
