Abstract
The utility model discloses a distribution box. The distribution box comprises a box body, a framework for supporting the box body and a box door, wherein as improvement, radiating grilles are arranged on the upper and lower sides of the box body; each radiating grille comprises radiating holes and a dust shield; the dust shield covering the radiating holes and the walls of the radiating holes are arranged in a dislocated manner to form a gap; the gap between the dust shield and walls of radiating holes of the grille on the upper side of the box body is larger than that between the dust shield and walls of radiating holes of the grille on the lower side of the box body; the gap between the dust shield and walls of radiating holes of the grille on the upper side of the box body is smaller than 1mm; and the grilles are arranged on the box door. The distribution box has the beneficial effects that the radiating grilles are arranged on the upper and lower sides of the box body, the dust shields are arranged on the radiating holes of the radiating grilles, and the dust shields covering the radiating holes and the walls of the radiating holes are arranged in a dislocated manner to form the gaps, thus being convenient for radiation and effectively preventing dust from entering the distribution box; and the distribution box has a simple structure and is convenient to produce.
Description
Technical field
The utility model relates to a kind of power distribution cabinet.
Background technology
In recent years, along with the development of China's modernization construction, urban and rural power grids constantly increased, and then power distribution cabinet is widely used.Existing power distribution cabinet is generally positioned at the cabinet of rectangular shape, and cabinet is provided with louvre.Power distribution cabinet much be arranged on industrial and mining enterprises with, operational environment is relatively poor, accumulates dust easily, of long duration, dust is more serious, dust is to the electronic product in the power distribution cabinet, heavy contamination influences its performance.
In addition, existing power distribution cabinet does not generally have heat abstractor.The general long-term use of power distribution cabinet, heat dispersion are related to the useful life of electronic product in the power distribution cabinet.The power distribution cabinet that has is provided with heat abstractor, and heat abstractor is arranged at the top of power distribution cabinet, but the winged insect invasion is arranged, and influences electronic product in the power distribution cabinet, and it is polluted and damages.
Summary of the invention
The utility model provides a kind of good heat dissipation to be convenient to the dustproof power distribution cabinet for solving the problem that prior art in use exists.
The technical scheme that the utility model solves existing issue is: a kind of power distribution cabinet, the skeleton, the cabinet door that comprise cabinet, support cabinet, as improvement, side and lower side are provided with the heat radiation barrier on the described cabinet, described barrier comprises louvre and dust excluding plate, be covered on dust excluding plate on the louvre and louvre hole wall and shift to install and constitute the gap, the dust excluding plate of the barrier of side and louvre hole wall gap are greater than the dust excluding plate and the louvre hole wall gap of cabinet lower side barrier on the described cabinet.The dust excluding plate of the barrier of side and louvre hole wall gap are less than 1mm on the above-mentioned cabinet.Above-mentioned barrier is arranged on the cabinet door.
As further improvement, described dust excluding plate and the adhesion of louvre hole wall part.
As further improvement, described dust excluding plate one opposite side and the adhesion of louvre hole wall.
The utility model compared with prior art, its beneficial effect is that side and lower side are provided with a heat radiation grid on cabinet, on the louvre of heat radiation grid dust excluding plate is set, being covered on dust excluding plate on the louvre and louvre hole wall shifts to install and constitutes the gap, both be convenient to heat radiation, can have prevented effectively again that dust from entering in the power distribution cabinet.The utility model is simple in structure, just with manufacturing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of barrier.
Embodiment
Referring to Fig. 1, the implementation case comprises cabinet 1, supports skeleton, the cabinet door 2 of cabinet 1, side 11 and lower side 12 are provided with heat radiation barrier 3 on the cabinet 1, barrier 3 comprises louvre 31 and dust excluding plate 32, be covered on dust excluding plate 32 on the louvre 31 and shift to install with louvre 31 hole walls and constitute the gap, the dust excluding plate 32 of the barrier 3 of side and louvre 31 hole wall gap h are less than 1mm on the cabinet 1.Cabinet 1 inner electrical heating, heated upward motion of air, the top forms normal pressure in the cabinet 1, the below forms negative pressure, the louvre 31 of the side 12 from the cabinet 1 of the air after the heating overflows with the gap in the dust excluding plate 13, and suck from lower side, therefore the dust excluding plate 32 of the barrier 3 of side 11 and the dust excluding plate 32 and louvre 31 hole wall gaps of louvre 31 hole wall gaps on the cabinet 1 greater than cabinet lower side 12 barriers 3, can be so that the air of heating be taken dust out of from last side, minimizing sucks dust from lower side, thereby plays the dustproof effect.For the ease of the cleaning dust, barrier 3 is arranged on the cabinet door 2.
Claims (5)
