An electrical current collector system comprising an electrically conductive slip ring mounted to a rotatable shaft and a fixed conducting ring assembly forming a partially enclosed AC high voltage electrical current conductive ring channel in which slip ring contacting members are mounted. A compartment at ground potential at least partially encloses the slip ring and the fixed conducting ring assembly. A source directs a fluid into the compartment so that the fluid travels through into the conductive ring channel to perform at least one of cooling and cleaning of the slip ring contacting members. A hollow conically shaped insulator has a frustum with a narrower cross-sectional opening connected to the conductive ring channel and a larger diameter cross-sectional portion passing through and connected to the compartment for exhausting the fluid from the current conductive ring channel.
La présente description porte sur un collecteur de courant électrique comprenant une bague collectrice montée à un arbre rotatif et un ensemble de bague conductrice fixe formant un canal de bague conductrice de courant c.a. haute tension partiellement fermé dans lequel les éléments en contact avec la bague collectrice sont montés. Un compartiment au potentiel terre renferme au moins partiellement la bague collectrice et l'ensemble bague conductrice fixe. Une source dirige un fluide dans le compartiment de sorte que le fluide traverse le canal de bague conductrice pour assurer au moins le refroidissement et le nettoyage des éléments en contact avec la bague collectrice. Un isolant creux de forme conique comporte un tronc avec une ouverture transversale plus étroite reliée au canal de bague conductrice et une partie transversale de diamètre plus grand passant à travers et reliée au compartiment pour assurer l'évacuation du fluide du canal de bague conductrice de courant.
