Abstract: front page image
(EN)The present invention relates to a system for grounding bearings of rotary electric machines (200), especially rotary electric machines (200) controlled by frequency converters, the system comprising an outer ring (1), a contact ring (2), a support ring (3), elements (4) for fastening the rings, optional closure elements (5), elements (6) for fastening the assembly, elements (7) for adjusting the brush, a brush (8) made of a conductive material and a compressive fastening element (9), wherein the outer ring (1) is provided with at least two, preferably four to six housing holes (8A) for housing one or more grounding brushes (8). The present invention further relates to an electric machine provided with a system according to the invention.
(FR)La présente invention concerne un système de mise à la terre de paliers de machines électriques tournantes (200), notamment pour des machines électriques tournantes (200) commandées par des convertisseurs de fréquence, comprenant un anneau extérieur (1), un anneau de contact (2), un anneau de support (3), des éléments de fixation des anneaux (4), éventuellement des éléments de fermeture (5), des éléments de fixation de l'ensemble (6), des éléments de réglage de balai (7), un balai de matériau conducteur (8) et un élément de fixation par compression (9), l'anneau extérieur (1) comportant au moins deux - de préférence quatre à six - trous de logement (8A) destinés à recevoir un ou plusieurs balais de mise à la terre (8). La présente invention se rapporte en outre à une machine électrique dotée d'un système selon l'invention.
(PT)A presente invenção se refere a um sistema de aterramento de mancais de máquinas elétricas girantes (200), especialmente para máquinas elétricas girantes (200) controladas por conversores de frequência, compreendendo um anel externo (1 ), um anel de contato (2), um anel de suporte (3), elementos de fixação dos anéis (4), eventualmente elementos de fechamento (5), elementos de fixação do conjunto (6), elementos de ajuste da escova (7), escova de material condutivo (8) e elemento de fixação por compressão (9), em que o anel externo (1) é dotado de pelo menos dois, preferencialmente de quatro a seis furos de alojamento (8A) para alojar uma ou mais escovas de aterramento (8). Além disso, a presente invenção se refere a uma máquina elétrica dotada de um sistema de acordo com a invenção.
