Abstract

L'invention concerne un dispositif de réduction acoustique des ondes provenant de la partie active et propagées dans le fluide diélectrique d'un appareillage électrique haute ou moyenne tension (1) comprenant une partie active par induction, caractérisé en ce qu'il comprend : -une enveloppe creuse et étanche, adaptée pour être soumise à des ondes mécaniques par une de ses faces, - des moyens de tenue au vide adaptés pour maintenir les faces de l'enveloppe dans leur limite élastique lorsque l'enveloppe est soumise par l'extérieur à la pression du vide. L'invention est une solution simple et efficace pour la résistance au vide des enveloppes lors de la mise au vide à l'intérieur de la cuve d'un appareillage à haute ou moyenne tension.The invention relates to a device for acoustic reduction of the waves originating from the active part and propagated in the dielectric fluid of a high or medium voltage electrical apparatus (1) comprising an active part by induction, characterized in that it comprises: a hollow and tight envelope, adapted to be subjected to mechanical waves by one of its faces, - vacuum holding means adapted to maintain the faces of the envelope in their elastic limit when the envelope is subjected from the outside at the vacuum pressure. The invention is a simple and effective solution for the vacuum resistance of the envelopes during the evacuation inside the vessel of a high or medium voltage switchgear.
