An enclosed cabinet for electrical switchgear comprises delimiting surfaces 5, 6, 7, 8, 9 clad with sheet metal or other material and arranged on a frame of supporting corner columns 1, 2, 3, 4. At least two corner columns are designed as steel profiles, which are bent in such a way that they have elasticity at right angles to the longitudinal direction of the profile, in the direction outwards from the inside of the cabinet. One of the delimiting surfaces consists of a door 5 which is secured pivotably on one corner column 1 and can be locked to another 4 by means of a locking bolt 11, which columns are designed as elastic profiles. The corner column profiles, the door and the locking bolt are designed in such a way that the passage for gas leaking out from the inside of the cabinet is formed between the bent portions of the profiles 1, 4, the door 5 and the locking bolt 11. <IMAGE> |
