The subject of the invention is an enclosure for secondary distribution modular switchgears, applicable in protecting switchgears both against adverse weather conditions and against unauthorized inspections of high, medium and low voltage switch gear, and also against accidental access by unauthorized persons, or by wild animals and birds. The inventive enclosure containing a base-frame (3) to which the enclosure walls are attached and which is provided with a roof cover is characterized in that the base frame (3) is formed by a metal truss and contains two extreme base-frame modules, the left one (20) and the right one (23,) and at least one middle module (21 and/or (22) which are connected with one another by means of a pair of permanent connections formed by a socket (27a) and a prong (27b) and fastening and earthing plates (28a, 28b).

1. Set for building an enclosure for secondary distribution modular switchgears, said set comprising wall elements to form enclosure walls,roof elements to form a roof, anda set of base-frame elements to form a base-frame composed of a metal truss,said enclosure walls being fixed on said base-frame and being covered by said roof to form said enclosure,said set for building an enclosure for secondary distribution modular switchgears being characterized in that said set of base frame elements comprisesat least three separate metal truss base-frame modules, comprising permanent coupling elements and being connectable with one another by means of a pair of said permanent coupling elements,each said permanent coupling element formed by an enclosed socket associated with one of said modules and a prong associated with another of said modules and extending from said module so as to face said module with said enclosed socket, andcorresponding fastening and earthing plates extending from said facing modules connected to each other with said prong fully received in said corresponding enclosed socket, wherein said fastening and earthing plates extend from a corresponding end of said coupling element that forms said enclosed socket and from a corresponding end of said coupling element from which said prong extends, said fastening and earthing plates positioned substantially adjacent one another and attached to one another when said prong is fully received in said corresponding enclosed socket,two of said modules forming the extreme base-frame modules, the left one and the right one and the at least third module forming the at least one middle module. 2. An enclosure as in claim 1 characterized in that at least one single switchgear panel is placed in a base-frame truss window formed in one of said truss base-frame modules. 3. The enclosure as in claim 2 characterized in that the windows of the base-frame truss have internal dimensions adjusted to the dimensions of a single switchgear panel, and the truss window width (W) corresponds to the width of one single switchgear panel, while the truss window length (L) corresponds to the length of the switchgear panel. 4. An enclosure as in claim 1 characterized in that the enclosed sockets are located in the extreme left base-frame module, and prongs are located in the middle base-frame module on one side of the module, while enclosed sockets are located on the other side of the middle base-frame module, and prongs are located in the extreme right base-frame module. 5. An enclosure as in claim 1 characterized in that a skid-frame is fastened to the base-frame and its skids are attached to brackets located in each base-frame module in the truss windows. 6. An enclosure as in claim 5 characterized in that the brackets are made of angle irons which are permanently fixed to the inner surface of the base-frame truss window. 7. An enclosure as in claim 1 characterized in that floor covers with cut-outs are fixed in the base-frame truss windows. 8. An enclosure as in claim 1 characterized in that the enclosure walls are fixed to the base-frame through a base beam which is a part of each wall module. 9. An enclosure as in claim 8, characterized in that the base beam is made from a bent profile, and at least one extreme left vertical beam or extreme right vertical beam is attached to the flat top surface of the base beam. 10. An enclosure as in claim 9, characterized in that the extreme vertical beams belonging to different wall modules of the enclosure are joined together by means of fixing bolts placed in openings that are made in surface margins being in contact with the adjacent mirrored part of the vertical beams. 11. The enclosure as in claim 1, characterized in that said base-frame modules are formed with at least two opposed beams connected at respective ends and in between by cross-wise beams, wherein said opposed beams and said crosswise beams have a tube of rectangular cross-section which form said enclosed sockets and which receive a corresponding said prong which has a rectangular cross-section sized to be received in said enclosed socket.
