FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of distribution devices for supply and distribution of electric energy, namely to the layout of a switching cabinet with a frame skeleton and a component of its internal configuration. In switching cabinet (1) with rectangular parallelepiped-shaped frame skeleton (2) of four vertical profiles (3) and eight horizontal profiles (4), four profiles (3, 4) form a rectangular shaped frame and two of four profiles forming profile frame and extending parallel to each other (3, 4) have respectively first mounting side (5) of the profile with the first row of spaced apart each other with observance of constant size (M) fastening sockets (6). At that, first profile fixing sides (5) are located in common plane (E) and on these first fixing sides (5) of the profile there is first component (7) of internal configuration extending between parallel profiles, which has mounting side (8) with second row of attachment sockets (9), which extends perpendicular to first row (6). Besides, in direction (y) of first row of fastening sockets (6) length there is a second row of attachment sockets (9) with observance of size (M) of raster of first row of fastening sockets (6) due to that as first row of fastening sockets (6) on first mounting side (5) of profile, and second row of attachment sockets (9) on mounting side (8) of component (7) of internal configuration are located in two-dimensional raster of holes. At that, raster distance in both measurements has raster size (M), internal configuration component (7) is internal configuration bus, which has mounting side (8) with inner line bus (7) extending in longitudinal direction, second row of attachment sockets (9) and with fasteners (25) formed on its opposite ends internal mounting bus (7) inside switching cabinet (1), and fasteners (25) are related to size (M) of raster of first row of fastening sockets (6) of first and / or second fastening sides (5, 11) of profile so that middle point of one of fastening sockets (6), respectively, in common plane (E) of profile fixing sides (5) is on straight line (G), on which the middle points of the second row of mounting seats (9) of mounting side (8) are located, if the internal fitting bus (7) is mounted in switching cabinet (1) through one of the profile fixing sides (5, 11).
EFFECT: increased density of package of components placed in switching cabinet due to arrangement in the direction of extension of the first row of fastening sockets of the second row of fastening sockets with observance of the size of raster of the first row of fastening sockets.
