ELECTRICAL APPARATUS WITH DUAL MOVEMENT OF CONTACTS COMPRISING A RETURN DEVICE WITH TWO LEVERS

摘要

The invention provides electric power line switchgear (10) comprising a main movable contact (14) and a secondary movable contact (16), capable of moving along a main axis A of the switchgear (10), in which the main movable contact (14) is connected to the secondary movable contact (16) by means of a crank mechanism (20) that transforms the movement of the main movable contact (14) in one direction into a movement of the secondary movable contact (16) in an opposite direction; the switchgear being characterized in that the crank mechanism (20) comprises two levers (22, 24) mounted to pivot relative to the stationary housing (12) about respective parallel pivot axes (B, C), each lever (22, 24) being connected firstly to a respective one of the main movable contact (14) and the secondary movable contact (16), and secondly to the other lever (24, 22).

主权项

1. Electric power line switchgear (10) comprising a main movable contact (14) and a secondary movable contact (16), each of which is capable of moving relative to a stationary housing of the switchgear along a main axis A of the switchgear (10) between a closed position of the switchgear (10) and an open position of the switchgear (10);
wherein the main movable contact (14) is connected to the secondary movable contact (16) by means of a crank mechanism (20) that transforms the movement of the main movable contact (14) in one direction into a movement of the secondary movable contact (16) in a direction opposite the direction of movement of the main movable contact; the switchgear being characterized in that the crank mechanism (20) comprises two levers (22, 24) mounted to pivot relative to the stationary housing (12) about respective parallel pivot axes (B, C), each lever (22, 24) being connected firstly the main movable contact (14) or the secondary movable contact (16), and secondly to the other lever (24, 22).
