TANDEM-JOINED FRAMEWORK OF SWITCHGEAR CUBICLE FOR MULTIPLE- CUBICLE SWITCHGEAR

摘要

FIELD: multiple-cubicle switchgear.;SUBSTANCE: multiple-cubicle switchgear 1 has tandem-joined frameworks confined in side frames 5. System perforation in side frames 5 has alternately arranged large and small holes 6, 7, 13, 14 asymmetrically disposed with respect to depth axis 10 and height axis 11 according to their size. Each time when frameworks are being joined, smaller hole 7 opposes larger one 6. When holes 6 and 7 are being adjusted to self-tapping screws 12, adjacent frameworks can be joined with aid of screws and tools on one respective end only. Additional holes 13, 14 are used for installing wiring interconnecting adjacent switchgear cubicles.;EFFECT: facilitated procedure of joining frameworks to form multiple-cubicle switchgear.;4 cl, 5 dwg
