Abstract
A fast control device for high-voltage switchgear, in particular a grounding disconnector which is equipped with a moving contact, which fast control device comprises a spring for storing mechanical energy, a cocking mechanism for cocking the spring and comprising an electric motor organized to rotate at least one rotary part organized to take up two stable positions corresponding respectively to the spring being cocked and to the spring being not cocked, said cocking mechanism being provided with a connection rod coupled to an actuating mechanism for actuating a moving contact, the connection rod being associated with a brake shock-absorber device. This brake shock-absorber device comprises at least one hydraulic shock-absorber co-operating with the connection rod and secured to the housing of the device via a spring member. By means of this brake shock-absorber device, the control device is effective, reliable, and its cost is particularly advantageous.
