Embodiment
The invention provides a kind of pre-installed transformer station box heat dissipation channel structure, clearer, clear and definite for making purpose of the present invention, technical scheme and advantage, below develop simultaneously with reference to accompanying drawing that the present invention is described in more detail for embodiment.
In order to solve the bad problem of pre-installed transformer station box heat dissipation channel effect in the prior art, innovative point of the present invention is: air intake passage and air-out passage are improved, the air-out passage is arranged on around the top of casing top cover, air intake passage is arranged on the bottom of transformer station box, by on the base of casing, increasing a bed hedgehopping layer, just on base, fix several interlaced arrangement of welding, the section bar cross section is the supporting base of U type channel-section steel, with the contour bottom half of supporting base around have a plurality of openings and install shutter on the wall at opening part, and one of welding has the through hole dividing plate that several are evenly distributed on the upper surface of supporting base, like this by the shutter on the wall box, the some U type cross section channel-section steels and the through hole dividing plate that are built in lower box are formed air intake passage, on box house through hole dividing plate, be placed with transformer, when moving, internal transformer work produces heat energy, utilize the chimney principle, cold wind is by shutter, after the air intake passage that supporting base and through hole dividing plate are formed enters by shutter, enter in the casing by the different through hole on the through hole dividing plate through detouring as the layout in mazy U type channel-section steel supporting base, make cold wind be full of whole nonmetal casing inside, components and parts are carried out efficiently radiates heat, hot-air rises then, air-out passage by the casing top is discharged, formed the exchange of heat, the temperature rise that makes whole box body inside is less than 5K.
In conjunction with shown in Figure 2, pre-installed transformer station box of the present invention comprises casing body 100, the top cover 101 that links to each other with the casing body, wherein the casing top cover is reverse V-shaped top, has the peristome 102 that top shutter 103 is installed around the top, and the shutter on the top constitutes the air-out passage; The present invention also comprises the air intake passage part that casing body 100 bottoms are elevated, air intake passage partly comprises: supporting base 300, have a plurality of aperture portion 500 on the box body wall around the supporting base 300, shutter 501 is installed at aperture portion 500 places and is also comprised a multi-through hole dividing plate 400, the diameter of multi-through hole dividing plate 400 through holes decides (diameter is generally less than 12mm, and every square metre hole number is not less than 120) according to the degree of protection of preassembled transformer station; Wherein: the section bar cross section of supporting base 300 is U type channel-section steel, the U type lower surface vertical fixing of channel-section steel is welded on the base 200, the U type upper surface of channel-section steel is vertically welded on the multi-through hole dividing plate 400, and the height of supporting base 300 and shutter 501 are highly suitable, its height is greater than 100mm, and scope is between 100-120mm; The density in hole is relevant on the layout density of supporting base 300 and the multi-through hole dividing plate 400, the quantity of general control supporting base 300 is half of hole number on the multi-through hole dividing plate 400, when cold wind sucks around following casing lower wall, drag effect by " U " font channel-section steel, upwards, constantly move, to the center thus the temperature rise that reduced whole box body inside.According to cross-ventilated principle, when temperature in the chimney is higher than outside the chimney temperature, hot-air is little because of density in the chimney, just rise naturally along these chimneys, the outer cold air of chimney is big because of density, is infiltrated by low layer and replenishes, this just forms stack effect, the chimney principle that the present invention utilized is the technology that the people in the industry knows, and specifically this air intake and air-out passage are how to dispel the heat, and its operation principle is not done detailed description.
3 is arrangement modes of supporting base 300 of the present invention and multi-through hole dividing plate 400 in conjunction with the accompanying drawings, among the figure, the supporting base 300 that is positioned under the multi-through hole dividing plate 400 comprises 6 groups of supporting bases, every group of two-phase border on the river square to supporting base U type channel-section steel in corresponding in twos, the position interlaced arrangement of notch, and the U type channel-section steel of every group of supporting base and adjacent one group of supporting base is to arrange back to notch, just the planar base surface of corresponding another group channel-section steel of the planar base surface of every group of channel-section steel; One embodiment of the invention is seen shown in Figure 3, have 12 row supporting bases, one group of per two behavior (that is: every group of two-phase border on the river square to supporting base U type channel-section steel in notch corresponding in twos, the position interlaced arrangement) to be divided into 6 groups of supporting bases be benchmark by Fig. 3 center line to the supporting base under multi-through hole dividing plate 400 300, (the said front and back of this specification are to be placed on before transformer frontal in the casing is for three groups of branch first three groups and backs, and the direction of transformer back is the back), first three groups and back are the mirror image symmetric arrangement for three groups, and several through holes 401 on the multi-through hole dividing plate 400 are evenly distributed on the multi-through hole dividing plate, each supporting base 300 is pressed the corresponding respectively through hole 401 of cross section horizontal direction and supporting base 300 of the through hole in every interval 401 distributions under the multi-through hole dividing plate, supporting base 300 is pressed cross section vertical direction through hole 401 for 400 times at the multi-through hole dividing plate quantity is identical or approximate with supporting base 300, the quantity of horizontal direction through hole 401 is nearly one times of the quantity of supporting base 300, in order to guarantee good ventilation effect, key of the present invention needs a bit to guarantee that the through hole 401 on supporting base 300 " U " type upper surface and the multi-through hole dividing plate 400 keeps at a certain distance away, just through hole of being opened on multi-through hole dividing plate 400 401 and supporting base 300 upper surfaces can not interfere with each other, need stagger mutually, otherwise will influence ventilation effect, the flow direction of the wind that the arrangement of this form makes in the air channel is just as entering in the labyrinth, so be referred to as labyrinth passage.
It should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
