Abstract

Cette invention se rapporte à un générateur électrique rotatif, qui comprend un stator (1) dont l'enroulement est constitué par un câble haute tension et qui est pourvu de dents (4) s'étendant radialement vers l'intérieur à partir d'un étrier externe (5). Au moins l'une des dents (4) du stator est reliée par au moins un tube de refroidissement (18) s'étendant radialement dans la dent (4) du stator et relié à un circuit de refroidissement (34) dans lequel circule un réfrigérant (36), le refroidissement s'effectuant sur au moins la majeure partie de l'extension axiale de la dent (4) du stator. Cette invention se rapporte également à un procédé de refroidissement d'un générateur électrique rotatif pourvu d'enroulements de stator haute tension, le stator étant refroidi par un réfrigérant (36) qui circule dans un circuit de refroidissement (34) le long de conduits de refroidissement s'étendant radialement à travers les dents (4) du stator.
