Abstract
The utility model discloses a top cap, particularly the top cap for a low-voltage electrical cabinet. The top cap for the low-voltage electrical cabinet has the advantages of good structural strength, ideal appearance effect and strong dustproof and waterproof capabilities. The top cap for the low-voltage electrical cabinet has a column structure, consists of a top plate and side walls and is provided with an opened bottom surface, and the side walls have ventilating structures.
Description
Technical field
The utility model relates to a kind of top cover, especially relates to a kind of top cover that is used for the low tension gas holder.
Background technology
Present employed low tension gas holder top cover is simpler, just be fixed with a block plate and be used for the enclosures top on the cabinet top, in order to increase heat sinking function, in the steel plate upper punch some ventilation holes are arranged, just because the existence of ventilation hole, caused following defective for described low-voltage electrical cabinet: cap structure intensity difference, depressed deformation easily; Radiating effect is poor; Dustproof, waterproof ability is poor, degree of protection is low; Install inconvenient; Have a strong impact on the overall appearance of cupboard.
The utility model content
Technical problem to be solved in the utility model is: the top cover that is used for the low tension gas holder that a kind of structural strength is good, appearance is good, the dustproof and waterproof ability is strong is provided.
The technical scheme that solves the problems of the technologies described above is: be used for the top cover of low tension gas holder, described top cover is the column structure of a bottom surface opened that is made of top board and sidewall, and described sidewall is provided with aeration structure.
Further be, the cross section of described sidewall is quadrilateral structure, is provided with aeration structure on each sidewall of described quadrilateral structure.
The optimal way of such scheme is that described aeration structure is ventilation hole or the shutter that is arranged on the described sidewall.
Further be that each sidewall of described top cover is formed by the sheet material bending that links to each other with top board.
The optimal way of such scheme is that described each side wall lower ends has turnup structure.
Further be to have at least the turnup structure of two sidewalls to be provided with installing hole in described each turnup structure.
The optimal way of such scheme is that the described installed inside that is provided with the sidewall of aeration structure has protection network.
Further be that at least one ventilating fan is installed on the described top board.
The beneficial effects of the utility model are: the top cover of the column structure by a bottom surface opened that is made of top board and sidewall is set at low tension gas holder counter, and on the sidewall of described top cover, establish aeration structure, owing on top board, there is not the ventilation hole structure, strengthened the intensity on regulator cubicle cabinet top, improve the waterproof and dustproof ability of top cover, and increased the overall appearance of cabinet.

Be labeled as among the figure: top board 1, sidewall 2, aeration structure 3, turnup structure 4, installing hole 5, ventilating fan 6.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be the top cover that is used for the low tension gas holder that a kind of structural strength is good, appearance is good, the dustproof and waterproof ability is strong that the utility model provides.Described top cover is the column structure of a bottom surface opened that is made of top board 1 and sidewall 2, and described sidewall 2 is provided with aeration structure 3.The top cover of described structure is owing to being the column structure, so structural strength is more far better than the structural strength of an original block plate; The top cover of described structure is installed to regulator cubicle, especially on the plane, the cabinet of low tension gas holder top, both can have played the effect of ventilation, because of ventilation hole is not set in the top board plane, so the water proof and dust proof ability is strong, effective; And it is very attractive in appearance to be installed in the cabinet top as a cap, has improved the visual effect of regulator cubicle product.
The sidewall 2 of described top cover can be a column structure, if adopt column structure, need roll during making, makes trouble, and cabinet body structure generally is cube structure, if top cover is made into circle, also inconveniently cooperates with cabinet; Electric components can produce a large amount of heats in the energising course of work in addition, if the heat that is sent can not dissipate, it is very high that the cabinet temperature inside is raised to, thereby makes the electric elements cisco unity malfunction in the cabinet or burn out described electric elements.So, be convenient to again cooperate with cabinet in order to make system convenient, fast, can also improve heat radiation, the draught capacity of electric cabinet simultaneously, the cross section of described sidewall 2 is quadrilateral structure, is provided with aeration structure 3 on each sidewall 2 of described quadrilateral structure.Do not need to roll during this making sidewall 2, easy to make, quick; Aeration structure 3 all is set on each sidewall 2 can improves heat radiation, draught capacity largely.Described aeration structure can be arranged on the ventilation hole on the described sidewall 2, also can be arranged on the shutter on the described sidewall 2.Adopt the above-mentioned ventilating opening and the structure of shutter, all exist dust in air to enter the interior shortcoming of cabinet easily,, will certainly cause damage, can not satisfy the requirement of electric equipment products degree of protection electric elements if a large amount of dusts enters cabinet.In order to improve dustproof grade, the described installed inside that is provided with the sidewall 2 of aeration structure 4 has protection network, and the general protection network that adopts common dustproof construction of described protection network so just can effectively improve the degree of protection in the regulator cubicle cabinet.Although increase the degree of protection that protection network has improved cabinet, but be unfavorable for ventilation and heat, the electric elements of installing in cabinet more for a long time, in order to improve the ventilation and heat function, on described top board 1, one or more ventilating fans 6 can be installed, so just, can effectively reduce the temperature in the regulator cubicle cabinet, play the effect of ventilation and heat.
Can be between top board 1 and the sidewall 2 for being welded to connect, also can connect for riveted joint, be welded to connect if adopt, because the wall thickness and the top cover material therefor of regulator cubicle cabinet are all thinner, so no matter be the connection of top cover self or top cover and being connected of cabinet, post welding distortion will be very big, be unfavorable for the attractive in appearance of appearance, workload also can increase greatly simultaneously, and is more attractive in appearance in order to make product, and the making workload is less again, each sidewall 2 of described top cover is formed by the sheet material bending that links to each other with top board 1, so do not need to weld between sidewall 2 and the top board 1, just there is not welding deformation yet, presentation quality can well be guaranteed; If but the sheet material bending that just directly will be connected with top board 1, the intensity of then described sidewall 2 a little less than, in order to improve the intensity of described sidewall 2, described each sidewall 2 lower end have turnup structure 4; Further in order to make top cover quick and convenient with being connected of cabinet, there is not bigger distortion again, have at least the turnup structure 4 of two sidewalls 2 to be provided with installing hole 5 in described each turnup structure 4, described installing hole 5 is used for top cover is installed to the regulator cubicle cabinet with bolt, install just quick and conveniently like this, also do not had very big distortion.Both save making man-hour, and can well guarantee the presentation quality of product again.
