Title
(EN) DEVICE FOR DETECTING AT LEAST ONE GAS IN A FLUID EMANATING FROM AN APPARATUS
(FR) DISPOSITIF DE DÉTECTION D'AU MOINS UN GAZ DANS UN FLUIDE ÉMANANT D'UN APPAREIL
Abstract
(EN)
A device for detecting gas to be monitored in a fluid such as oil emanating from an apparatus such as a transformer, comprises an enclosure and a chamber for extracting the gases contained in the fluid, a measurement chamber containing sensors for detecting the gases to be monitored, and an air drying chamber having an air drying member. The chambers communicate through an arrangement of tubes having lengths and internal diameters such that transfers of gas between the chambers by diffusion in the tubes are negligible without pressure differential produced in the tubes by a pump operated by a circuit.
(FR)
Un dispositif de détection de gaz à surveiller dans un fluide comme de l'huile émanant d'un appareil comme un transformateur, comporte une enceinte et une chambre d'extraction des gaz contenus dans le fluide, une chambre de mesure contenant des capteurs pour détecter les gaz à surveiller, et une chambre d'assèchement d'air ayant un organe d'assèchement d'air. Les chambres communiquent par un arrangement de tubes ayant des longueurs et des diamètres intérieurs tels que des transferts de gaz entre les chambres par diffusion dans les tubes soient négligeables sans différentiel de pression produit dans les tubes par une pompe opérée par un circuit.
