| 摘要 |
The invention relates to an actuator device (1) for at least one electrical device for a line having a housing with the same profile adjacent thereto on an attachment rail, said protection device comprising a mechanical lock for cutting off at least one protected line and being provided with a manual control switch that is movable between at least two positions that correspond to the opening and closing of said line(s), respectively, including: a drive means (9) and a transmission system consisting of a set of gears (10, 11, 12, 13, 14) connecting the drive means (9) and a rotary lever (4) which can be secured to the control switch of the adjacent protection device, said drive means (9) being capable of moving the lever (4) between two end positions corresponding to the open and closed positions of the switch of the protection device. The transmission system comprises a rotary means for driving the rotary lever (4) in two opposite directions of rotation, said driving means having an angular displacement substantially equal to twice the angular path covered by the switches of the associated line-protecting devices, a means for controlling the drive means (9) making it possible to reset the position of the drive means after driving the switch at one of the end positions thereof into a middle point between said positions by a reverse rotation equal to an angular path of the switch. |
