Title
(EN) DISTRIBUTION OF A DIELECTRIC GASEOUS MIXTURE TO A HIGH-VOLTAGE APPARATUS
(FR) DISTRIBUTION D'UN MÉLANGE GAZEUX DIÉLECTRIQUE VERS UN APPAREILLAGE HAUTE TENSION
Abstract
(EN)
Method for distributing an electrically insulating liquefied gaseous mixture to a high-voltage electric apparatus from a storage means containing an insulating gaseous mixture, said method comprising the following steps: - Step a): heating said insulating gaseous mixture up to a temperature such that the content of the storage means is a homogeneous fluid; - Step b): tapping the insulating mixture from step a) to fill a high-voltage electric apparatus by raising the temperature of said mixture from step a), characterised in that, during step b), a variable pressure regulation setpoint, calculated in real time from the weight of the storage means, is applied when the variation from the pressure setpoint is less than 0.2 bar per 1kg/m3 of density variation, then a constant temperature regulation setpoint is applied until the content of the storage means is emptied.
(FR)
Procédé de distribution d'un mélange gazeux liquéfié isolant électrique vers un appareillage électrique à haute tension depuis un moyen de stockage contenant un mélange gazeux isolant, ledit procédé comprenant les étapes suivantes : - Etape a) : chauffage dudit mélange gazeux isolant jusqu'à une température telle que le contenu du moyen de stockage soit un fluide homogène; - Etape b) : Prélèvement du mélange isolant issu de l'étape a) pour remplir un appareillage électrique à haute tension en rehaussant la température dudit mélange issu de l'étape a); caractérisé en ce que, pendant l'étape b), on applique une consigne de régulation à pression variable, calculée en temps réel à partir de la pesée du moyen de stockage, quand la variation de la consigne de pression est inférieure à 0,2 bar pour 1 kg/m3 de variation de la masse volumique, puis on applique une consigne de régulation à température constante jusqu'à ce que le moyen de stockage soit vidé de son contenu.
