Abstract
The invention relates to electrical engineering, in particular to designs of single-pole high-voltage vacuum switches of outer unit intended for operation on feeders of contact network of traction substations of electrified railroads at alternating current with voltage 27.5 kV. Design of the invention has pole arranged as column with vacuum arc-suppression chamber and mechanism for displacement if its movable contact, and drive that is kinematically connected to that mechanism. Design of the invention has pole arranged as column with vacuum arc-suppression chamber and mechanism for displacement of its movable contact and drive that is kinematically connected to that mechanism.
