SWITCHGEAR INSTALLATION USING MODULAR COMPOSITE BUS SYSTEM AND HAVING NO CURRENT-CARRYING PARTS ON ITS FACE Russian patent published in 2007 - IPC H02B1/20 H01R11/09 

FIELD: electrical engineering.

SUBSTANCE: proposed improved-design switchgear installation that can be used for sectionalizing power cable network has bus system assembled of modular parts, such as high-voltage cables, connectors joined to cables, and third cable-free bus assembled using mechanical and/or plug-in connections. Using such buses enables assembly of bus systems of different mechanical design with differently disposed phase planes and of different size. Connectors and cable-free bus may have both plug-in and mechanical connection points, and combinations thereof. Buses proper may have insulation and semiconductor screens. Improved switchgear installation may also have solid insulation, such as EPDM rubber, for insulating bus system from external surfaces of switchgear installation.

EFFECT: ability of assembling bus systems of different mechanical design and different disposition of phase planes, as ell as of different size from buses of proposed type.
