A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; wherein said second switching unit includes an emergency control arrangement activatable by a user to make said second switching unit to carry out an opening manoeuvre.

Hybrid switching apparatus of the withdrawable type

A switching apparatus for electric power distribution grids including a first switching unit having one or more first electric poles, each first electric pole being electrically connectable with a corresponding first line conductor of an electric line and including one or more solid-state switches adapted to operate in a conduction state or in an interdiction state to allow or interrupt a current flow, and a second switching unit having one or more second electric poles, each second electric pole being electrically connectable with a corresponding second line conductor of said electric line and electrically connected in series with a corresponding first electric pole of said first switching unit. The switching apparatus further includes a controller implementing a robust control logic to the operation of said first and second switching units.

Switching apparatus of the hybrid type including solid-state switches in series with electro-mechanical switches

A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; and a controller implementing control strategies directed to increase the safety of the withdrawal manoeuvres of said first and second switching units.
