Abstract (en)

[origin: EP3770938A1] The present invention decreases an insulation distance between a vacuum switch and its peripheral components of equipment and improves the insulation characteristic of the vacuum switch. A solid dielectric vacuum switch includes a vacuum interrupter (1) having a fixed electrode (3a), a movable electrode (5a), a fixed conductor (3b) that is connected to the fixed electrode, and a movable conductor (5b) that is connected to the movable electrode; an insulated actuating rod (20) that is mechanically connected to the movable conductor; an actuator (30) that actuates the insulated actuating rod; and a solid insulator (21) covering the vacuum interrupter. A ground layer (23) covering an outer surface of the solid insulator is provided. A conductive shield (13) is provided within the solid insulator, the conductive shield covering around a connection portion between the movable conductor and the insulated actuating rod.
