Safety device for use on e.g. electromechanical meter for single-phase electrical network, during intervention, has blade made of electrically insulating material and mounted perpendicular and translatably movable to and along crosspiece

摘要

The device (2) has supporting units adapted to be attached and alternately disconnected with an electrical apparatus. A crosspiece (12) connects the supporting units, and a blade (20) made of an electrically insulating material is mounted perpendicular and translatably movable to and along the crosspiece. The blade is arranged to extend between wires from the apparatus. The blade is mounted swiveling on a carriage (18) that is mounted slidably along the crosspiece. Notches are arranged to immobilize the carriage on the crosspiece in a set of positions.
