Abstract:
1. A structure for supporting a main portion of an electrical apparatus for electrical control or protection in a medium-voltage electrical cell, when said structure is supported on a bearing surface, said structure comprising: two sides that are substantially parallel with one another, each side comprising a main portion from which extends a portion forming a wing, said wings being connected to one another at their free ends and at their ends connected to the main portion of the sides by, respectively, two upper crossmembers, the wings forming, at their junctions with the main portions of the sides, an opening for slidingly receiving, respectively, the two ends of a first said upper crossmember, the structure comprising first abutment and locking means that are carried partly by the first upper crossmember and partly by the sides, for preventing relative movement of said first upper crossmember relative to the structure in five of six degrees of freedom, the sixth degree of freedom corresponding to a direction opposite to the direction of insertion of the first upper crossmember, said first abutment and locking means being stopped by fastening means carried partly by the first upper crossmember and partly by the sides, so that installation of the said first upper crossmember alone in said opening prior to use of fastening means is sufficient to make the structure stable under the effect of gravity.
