FIELD: electrical engineering.
SUBSTANCE: proposed low-voltage switchgear has draw-out equipment module to receive switching, protective, and control devices. Housing of draw-out equipment module accommodates interlocking beam disposed across direction of displacement and provided with retaining beaks projecting on one side. Side flanges of compartment base mount positioning links engageable with retaining beaks for retaining draw-out equipment module in wiring, repair, and check-up positions. Interlocking beam is set to operating position by means of leverage controlled by actuating element disposed on front control panel. Closing auxiliary interrupting contact in repair position of draw-out equipment module sets the latter in check-up position. Interlocking beak functions to lock interlocking beam in the process thereby preventing draw-out of equipment module.
EFFECT: provision for setting equipment module to check-up position and for preventing its shift from this position; simplified design.
