Abstract

Projecteur électrostatique rotatif de produit de revêtement et i nstallation de projection comprenant un tel projecteur Ce projecteur électrostatique rotatif (10) de produit de revêtement comprend un bol de pulvérisation (106), un corps (102), une turbine d’entraînement montée dans le corps et configurée pour entraîner le bol de pulvérisation en rotation autour d’un axe de rotation (A100) défini par le corps. Le projecteur comprend également des électrodes (146) de charge de produit de revêtement pulvérisé par le bol de pulvérisation, ces électrodes étant montées sur une bague (160) rapportée sur le corps et chacune alimentée en haute tension à travers une résistance. Chaque résistance (180) s’étend axialement à l’extérieur de la bague (160) et est équipée, à son extrémité opposée à l’électrode (146) qu’elle alimente, d’une première fiche (208) de branchement électrique sur une deuxième fiche de géométrie correspondante prévue sur le corps (102), avec un mouvement parallèle à l’axe de rotation, et en ce que la bague (160) est configurée pour être montée et branchée (F2) sur le corps (102), ou démontée et débranchée (F1) du corps, en étant équipée des électrodes (146) et des résistances .
