Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-3, an assembled dampproofing heat dissipation high tension switchgear, including the cabinet body 1, locate the air exhauster 2 and the air inlet dehydrating unit 3 of slidable mounting in cabinet body 1 bottom at cabinet body 1 back, the bottom of cabinet body 1 sets up horizontally slip track 4, the bottom slidable mounting of air inlet dehydrating unit 3 is in on the slip track 4, this slip track's design can adopt slip mode or roll mode, and the outer end of air inlet dehydrating unit 3 is provided with handle and baffle, and the baffle is laminated with the cabinet body, when necessary, can set up locking structure such as hasp to and seal structure such as sealing washer, and under general condition, the cabinet body itself is not sealed yet, consequently is not high to sealing performance's requirement, just can play the effect of location through the orbital frictional force of the weight of air inlet dehydrating unit 3 self.

The inside wind channel 5 that sets up the L shape of air inlet dehydrating unit 3, wind channel 5 is including the vertical section 5-1 that is used for the air inlet and the horizontal segment 5-2 that is used for the air-out, built-in draught fan 6 in the wind channel, the draught fan is located the first half section of horizontal segment 5-2, sets up the exhaust vent on the lateral wall of the second half section of horizontal segment 5-2, and the mesh lets the air current dispersion, and it is internal to get into the cabinet from the bottom as many angles as possible, avoids under the unified condition of air current, the region of cover is too few.

The vertical section 5-1 is provided with a plurality of layers of pull-type moisture-proof layers 7, the lower end of the vertical section 5-1 is provided with a water collecting tank 8, the bottom surface of the water collecting tank 8 is lower than that of the horizontal section 5-2, the bottom of the water collecting tank 8 is provided with a water outlet 8-1, and a valve 8-2 is arranged at the water outlet 8-1.

The air current gets into from vertical section 5-1 under the effect of draught fan 6, after multilayer dampproof course 7, filters most moisture in the air current, and the gas that finally collects is dry gas, and dry gas gets into the cabinet body after, takes place heat exchange again with in the cabinet body, and produced moisture is extremely limited, and the time of passing through is short, and is fast, can not cause the threat to the internal electric elements of cabinet again basically.

When the moisture-proof layer 7 is forgotten to be replaced, so that the water vapor is too much, or under the condition of special weather, the water vapor is too much, and a large amount of water drops are condensed and seeped, the water drops can be temporarily stored in the water collecting tank 8 below the vertical section 5-1, the water drops are prevented from entering the horizontal section 5-2 of the air channel 5, and then the water drops are prevented from flowing into the cabinet body, and the water collecting tank 8 needs to be regularly drained.

Specifically, the vertical section 5-1 is provided with paired drawing slide rails 8 at positions for mounting the moisture-proof layer 7, the sections of the drawing slide rails 8 are T-shaped, and the openings of each pair of drawing slide rails 8 are opposite; moisture barrier 7 includes frame 9, dampproof board 10 and hand-strap 11, the both sides limit of frame 9 slides and sets up in the pull slide rail 8 of T shape, dampproof board 10 clamps in the frame 9, be provided with sliding seal 12 on the both sides limit of frame 9, the outer end at frame 9 is installed to hand-strap 11, be equipped with on the hand-strap 11 and correspond the sealing strip 13 of the vertical section in wind channel.

In this embodiment, the filler of the moisture-proof sheet 10 is made of a material having good permeability and water absorbability, such as porous silica gel.

The drawing slide rail 8 is in sliding fit with the outer frame 9, the sliding seal strip 12 is used for sealing, the main purpose of the drawing slide rail is to prevent water drops excessively generated from leaking downwards from the rail and prevent a large amount of wind from passing through the rail, the handling capacity of the moisture-proof plate for air flow is improved, the sealing requirement is not high, the main reason is that the sealing performance of the cabinet body is not enough, and therefore the effect is the optimized effect and is not a necessary structure.

In order to prevent the water vapor from dripping downwards from the edge after condensation, the outer frame 9 is integrally of a bucket-shaped structure with a large periphery, a small inner periphery and a downward closing-in, so that water drops of liquid are condensed towards the middle and fall onto the moisture-proof plate 10, the whole thickness of the outer frame 9 is consistent with the height of the hand-pulling plate 11, and the whole outer frame can be pulled out.

When in specific use:

the working personnel is required to make a regular maintenance plan according to the local environment, the damp-proof plate 10 is replaced and aired regularly, the air channel and the draught fan are cleaned and maintained regularly, the valve on the water collecting tank 8 is opened regularly to drain water, and the whole air inlet dehumidifying device 3 can be replaced if necessary.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
