CA 2169967

The present invention relates generally to global noise or sound control and, more particularly, to the control of sound radiated from stationary induction apparatus such as power transformers (1) and shunt reactors by use of active enclosures and active panels (6). The purpose of the invention is to markedly reduce the radiation of sound from the machine to all observation points in the surrounding field with a very lightweight, compact, non-airtight structure (5, 6, 7, 8, 9, 10, 11) which does not impair maintenance or repair of the machine.

L'invention concerne la lutte contre le bruit et plus particulièrement, la lutte contre le bruit émis par un dispositif fixe à induction, tel qu'un transformateur de puissance (1) et un réacteur en dérivation au moyen d'enceintes et de panneaux efficaces (6). Le but de l'invention est de limiter considérablement l'émission de bruit provenant de la machine au niveau de tous les points d'observation du milieu environnant au moyen d'une structure très légère, compacte et non étanche à l'air (5, 6, 7, 8, 9, 10, 11) ne constituant pas un obstacle pour l'entretien ou la réparation de la machine.
