It is in situ in described the when elastic piece, the moving block turn to latter second elastic piece and be bonded with first elastic piece
The heating wire in the cavity volume in one through hole coordinates with the conductive contact blade to be powered.Using the structure, lead in switchgear
During wind, air all enters in cabinet by first through hole after silica-gel desiccant absorbs water, therefore ensures to coagulate in cabinet
Dew, and weight increase after the silica-gel desiccant water suction to a certain extent in first through hole so that the second elastic piece crosses first
It is in situ in described the when elastic piece, the moving block turn to latter second elastic piece and be bonded with first elastic piece
The heating wire in the cavity volume in one through hole coordinates with the conductive contact blade to be powered, will during heating wire is powered
Originally the vapor absorbed is evaporated from the second through hole by heating, and enters the close of cylindrical shell after then rotating again
Closed region, so circulation, so as to reach the function that switchgear is non-maintaining, automatic drying is anti-condensation.
In above-mentioned technical proposal, it is preferred that the first through hole and the second through hole section are the identical sector of shape,
The cavity volume section is matched with the first through hole and second through hole.The sky of cylindrical shell is made full use of using the structure
Between, and installation easier to process.
In above-mentioned technical proposal, it is preferred that the moving block both ends are both provided with ring support, the institute of each cavity volume
State and be provided with pilot hole in the middle part of ring support, the heating wire is inserted in the pilot hole.Heating wire is caused using the structure
Convenient installation.
Compared with prior art, the present invention have the advantages that：Using the structure, when switchgear is divulged information, air
All enter by first through hole after silica-gel desiccant absorbs water in cabinet, thus ensure in cabinet will not condensation, and the
Weight increase after silica-gel desiccant water suction to a certain extent in one through hole so that the second elastic piece crosses the first elastic piece, institute
When stating moving block and turning to latter second elastic piece and be bonded with first elastic piece, original position is in the first through hole
The heating wire in the cavity volume coordinates with the conductive contact blade to be powered, and absorbs script during heating wire is powered
Vapor is evaporated from the second through hole by heating, and the closed area of cylindrical shell is entered after then rotating again, such as
This circulation, so as to reach the function that switchgear is non-maintaining, automatic drying is anti-condensation.
