SHELL OF 15-35 kV SWITCHGEAR CABINET Russian patent published in 2024 - IPC H02B11/00 H05K5/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to designs of switchgear cabinets for rated voltage from 15 kV to 35 kV, intended for use in power engineering and electrical industry. Technical result is achieved by the fact that enclosure of 15–35 kV switchgear cabinet contains frame (1) and at least one swing two-leaf door, flaps of which (2, 3) have a protruding part, when the door is closed, into the inner space of the switchgear cabinet shell, which is limited by frame (1); projecting part side surfaces are conjugated with switchgear cabinet shell frame surface along the entire length, along the line of contact of doors flaps first fold (2) has a U-shaped bend, located so that the second flap overlaps the bend of the first flap, wherein on the outer side of the surface of first flap (2) of the door inside the bend, a locking system is fixed with guiding elements of a cone-shaped shape and two bolts (8), fastened freely through the grooves by the mushroom-shaped fixing elements, bolts (8) are connected by a folding hinge mechanism, and their parts, when first flap (2) is locked, go outside the cabinet shell elements, where the locking bars of the deadbolts are also located.

EFFECT: increased reliability of closing and locking of swing two-leaf doors of 15–35 kV switchgear cabinet shell taking into account possible emergencies, which makes it possible to reduce width of doors and service corridors in front of switchgear cubicles, to increase operator safety level.
