Device for Electrical Connection of a bar which belongs to an electric Conductive bar with a bushing which belongs to the Insulating cover of an electrical switching device

摘要

A device for Electrical Connection of at least one Bar (2), which belongs to an electric Conductive Rod bushing (1) belongs to an Insulating Cover for an electrical switching apparatus, which comprises a Conductive insert the bushing (3) surrounded by at least Mane Ra through an insulation part (1D), Said Device comprising means (10, 10,10b) for Electrical connection between the end (2a) of the bar and the aforementioned Conductive insert (3), and a baffle (4) formed by a Conductive Shield designed to be electrically connected to the rod (2) and placed around the area of Electrical connection (5) The bar (2) and (3) the insertion.This baffle is molded from a flexible material, which in the mentioned material to form a sleeve (6) of substantially Cylindrical Shape designed to account for the stiffness of the deflector Shield, to push through his Extreme part located on the same side of the The insulation device (1D) from the Hub (1) above,That presents a complementary manner, with a certain pressure, so as to achieve a perfect tightness between the flexible material and the Insulating bushing, so as to ensure a better Sealing Dielectric on substantially the whole of the circunferenc The lower part of the sleeve of the previously mentioned.
