The drive mechanism of the indicating contacts of an electrical apparatus, in particular of a disconnector or grounding switch high voltage.

摘要

The present invention relates to a drive mechanism of a rotary switch signalling (1) of a high voltage electrical apparatus, in particular of a disconnector, or a grounding disconnector, connecting the switch by its rotation shaft (5) to a rotary shaft of an actuating mechanism of the contacts of the apparatus so that the contacts of the contactor are open or closed when the contacts of the apparatus are open or closed, this actuating shaft being displaced at a speed omegaht during a maneuver of opening or closing of the contacts of the apparatus. & br / the drive mechanism is a positive action between the actuating shaft and said rotation shaft (5) and comprises means for driving the rotation shaft (5) of the switch at the start and end of operation at a speed greater than omegaht omegacs.
