Middle voltage load break switch and application to a middle voltage cell and a middle voltage post

摘要

Multipole load break switch comprising, for each pole, an insulating bushing enclosing an evacuated bulb, the bushing including at a first end a first contact connected to a first terminal of the bulb and intended to cooperate with a first conductor, and at a second end a second contact connected to a second terminal of the bulb and intended to cooperate with a second conductor, the bushings being integral with a common metal section (4) shrouding a common shaft (38) for operating the bulbs (14) and which is actuated by a mechanism contained in a cabinet (5) integral with the section. Applications to medium-voltage cells and substations. IMAGE
