Abstract

La présente invention concerne un sectionneur de ligne comportant un bras (1) pivotant dans un plan, portant à son extrémité libre un contact mobile (2) et entraîné en pivotement à son autre extrémité par un mécanisme d'entraînement (3) porté par au moins une première colonne isolante (4) et un contact fixe (6) porté par une seconde colonne isolante (7) et recevant le contact mobile (2) en position fermée (A) du sectionneur, le bras (1) étant en position sensiblement perpendiculaire à cette position fermée en position ouverte (B) du sectionneur. La première colonne isolante (4) porte un contact de mise à la terre (8) et le mécanisme d'entraînement (3) permet le pivotement du bras (1) dans une position sensiblement perpendiculaire inverse (C), où le contact mobile (2) vient en prise avec ce contact de mise à la terre (8).The present invention relates to a line disconnector comprising an arm (1) pivoting in a plane, carrying at its free end a movable contact (2) and pivotally driven at its other end by a drive mechanism (3) carried by the at least a first insulating column (4) and a fixed contact (6) carried by a second insulating column (7) and receiving the movable contact (2) in the closed position (A) of the disconnector, the arm (1) being in substantially the position perpendicular to this closed position in the open position (B) of the disconnector. The first insulating column (4) carries an earthing contact (8) and the drive mechanism (3) allows the pivoting of the arm (1) in a substantially perpendicular reverse position (C), where the movable contact ( 2) engages this grounding contact (8).
