As shown in fig. 4 and 5, the moisture barrier assembly further includes a first gate-shaped bar (not shown), a second gate-shaped bar 270, and a third gate-shaped bar 440; the first and second gate bars 270 are connected to the inner wall of the fourth inner panel 240; a side surface of the first baffle, which is directly opposite to the third inner plate 230, is in contact with the first gate bar; a side of the second barrier directly opposite to the third inner panel 230 is in contact with the second gate bar 270.

The third gate bar 440 is connected to an inner wall of the first outer plate 410, and a side of the third barrier, which is away from the first outer plate 410, is in contact with the third gate bar 440.

Through setting up first door type pole, second door type pole 270 and third door type pole 440 for first baffle and second baffle are laminated in the inner wall of fourth inner panel 240 all the time, make the third baffle laminate in the inner wall of first planking 410 all the time. The structure is more compact, and the condition that silica gel granule appears leaking can be prevented.

As shown in fig. 5 and fig. 6, in another embodiment of the moisture-proof and condensation-proof hua-type box transformer substation switch cabinet, the bottom wall 420 is inclined toward the first outer plate 410, and at this time, the top of the fan sleeve 600 can contact with the sidewall of the regeneration chamber 400, so that the silica gel particles in the regeneration chamber 400 can more easily roll down into the storage chamber 200.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
