Patent ID: 6976862

Claim:
An interconnection assembly for electrical switchgear cells, applicable to modular cells that incorporate parts of operation and protection equipment of electrical distribution and transformation stations, comprising an independent connector element housed in each pan, previously coupled to the cells, in correspondence with conductor terminals to be joined and permitting offsetting of misalignments between conductor terminals, the pans permitting an attachable cap when an electrical connection is not required, an electrical isolation of the terminal situated in a bottom of the cap itself being formed, providing a leakproof coupling both mechanically and electrically, of the independent connector element to the conductive terminal of the pan, the independent connector element comprising: an external mount of elastic material provided internally and partially on the outside with a semiconductor to assure good control of the electric field; a pair of metallic tubes of a total length less than that of the external elastic mount, arranged internally in the mount and approximately in correspondence with its outermost sectors, in order to leave a central zone of the external and elastic mount free; a metallic ring and conductor housed directly in an interior of the elastic mount; and a bundle of conductive parts mounted axially in respective passages provided radially in the metallic ring, the conductive ring being in correspondence with the central zone, intercalated between facing ends of the metallic tubes, and fitting tightly between the ring and the mount, the conductive parts being spaced sufficiently from the metallic tubes to permit a degree of swiveling of the bundle formed by those conductive parts in order to offset possible misalignments between the conductive terminals to be connected.
