LOW-VOLTAGE SWITCHGEAR AND CONTROL GEAR Russian patent published in 2008 - IPC H02B11/173 H02B1/20 

FIELD: electrical engineering; cabinets for low-voltage switchgear and control gear designed for electrical energy distribution and metering.

SUBSTANCE: proposed low-voltage switchgear and control gear has at least one power cabinet with draw-out modules, each of the latter being provided with mechanism for locking them in desired positions and bus compartment with mainline and distribution bused installed in top part. Bus bridge is formed by mainline buses set on edge and clamped throughout their entire length by means of bus holders; each of the latter has two transversal load-bearing members. Bottom load-bearing member is secured on cabinet framework and top one is mounted on bottom load-bearing member by means of fastening members for holding down mainline buses. Bus bridge is equipped with insulators having protruding members on their supporting surfaces. Each load-bearing member has longitudinal row of holes to receive mentioned protruding members of insulators provided with slots on locating surfaces for disposing mainline buses on them.

EFFECT: improved performance characteristics, enhanced safety.
