Abstract

The invention relates to a functional locking cabinet for a medium tension switchgear. Functional locking cabinet for a medium tension switchgear comprising, within a casing closed by an access panel, at least one switch, a ground isolator and a mechanism for operating these systems, said mechanism comprising for each one of the systems a shaft which can adopt in rotation two given angular positions corresponding respectively to the open-circuit or closed-circuit condition of the system, each shaft being equipped with a disc equipped with a slot, the position of which corresponds to the open-circuit or closed- circuit condition of the system with which it is associated, said cabinet being characterised in that it comprises a first lock (3) which can be moved into two positions, a second lock (5) having two positions and two levers (6, 7) for driving the locks. Application: medium tension switchgear.
