Abstract
The utility model discloses a prepackage type transformer substation uses prevent wind sandbox, prevent wind sandbox include the box, still include the shutter that sets up at the anterior air intake of box, the dust board that the box middle part set up, the laying dust board that the bottom half set up. Prevent wind sandbox pass through shutter air inlet and built -in dust board and laying dust board, prevent effectively that thick sand blown by the wind from getting into, be applicable to the serious regional prepackage type transformer substation of sand blown by the wind, simple structure, simple to operate, area is little, the practicality is strong.
Description
Technical field
The utility model relates to electric power project engineering field, especially relates to the windproof sandbox of one being applicable to dust storm prone areas preassembled transformer station.
Background technology
The development of photovoltaic plant reaches its maturity, but does not also far improve for ruthless area protective capacities, and desert region sandstorm annoyings the safe operation of electric fixtures, also attendant is increased to the workload of many deashings simultaneously.The anti-dust measure that current field box becomes is all add filter cotton with shutter to be directly placed in transformer station box sidepiece air intake; often cleaning is needed for sand and dust more regions or changes filter cotton; otherwise improper ventilation, the inverter at high temperature low even disorderly closedown of operational efficiency will be caused, have a strong impact on photovoltaic generation and normally run.
Utility model content
The purpose of this utility model is exactly the situation for above-mentioned prior art, and propose the preassembled transformer station improper ventilation that a kind of windproof sandbox solution sand and dust more regions causes, inverter at high temperature operational efficiency is low, the even problem of disorderly closedown.
The purpose of this utility model is achieved through the following technical solutions: a kind of windproof sandbox, comprise casing, also comprise laying dust plate, dust board and shutter, described shutter is fixed on the air inlet of casing front portion, described dust board is fixed on the upper middle part of box house, and described laying dust plate is located at bottom half.
Further, described shutter is the curved shutter of S.
Further, described dust board is provided with bending angle A, 90 ° of < A≤180 °.
Further, described laying dust plate is draw and insert-type.
The beneficial effects of the utility model are: be with the distinguished and admirable by being stopped most of rough sand dirt by shutter during air intake of sand and dust, meet with dust board again, make sand and dust dive downwards on laying dust plate produce deposition, remaining fine sand dirt upwards to air outlet place, therefore reaches the object of filtering rough sand dirt with distinguished and admirable continuation.Be applicable to the regional preassembled transformer station that dust storm is serious, have structure simple, easy for installation, floor space is little, practical advantage.
Accompanying drawing explanation
Fig. 1 is a kind of windproof sandbox generalized section of the utility model;
Fig. 2 is the dust storm flow graph of a kind of windproof sandbox of the utility model.
Description of reference numerals: 1-casing, 2-laying dust plate, 3-dust board, 4-shutter.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of windproof sandbox of the utility model is described further: this embodiment is only not used in restriction scope of the present utility model for illustration of the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model all falls within the application's claims limited range.
As shown in Figure 1, the windproof sandbox of one described in the utility model, comprise casing 1, also comprise laying dust plate 2, dust board 3 and shutter 4, described shutter 4 is fixed on the air inlet of casing 1 front portion, described dust board 3 is fixed on the upper middle part of casing 1 inside, and described laying dust plate 2 is located at bottom casing 1.
Described shutter 4 is the curved shutter of S, has two anti-features:
(1) rainproof: within the scope of air intake 180 °, dabbling of any direction all can not enter box house;
(2) sand prevention: air intake has catches rough sand dirt function, can effectively stop entering of bulky grain sand bed, for the ventilation in the large area of dust storm provides Reliable guarantee.
Described dust board 3 is provided with bending angle A, 90 ° of < A≤180 °, described dust board 3 has dust-break effect: obstruct by dust board 3 after being entered in case by the sand and dust of air intake and directly can not arrive air outlet and detour downwards and upwards circulate, sand and dust are forced to produce sedimentation downwards, thus reduce sand and dust and arrive air outlet, dust board 3 has and changes wind direction and cause sand and dust to dive downwards, extend distinguished and admirable path and make the effect of soil deposition.
Described laying dust plate 2 is draw and insert-type, and described laying dust plate 2 has the function can artificially extracted out after sand and dust are piled up, easy cleaning.
As shown in Figure 2, this example windproof sandbox general principle is as follows: rough sand dirt is stopped most of rough sand dirt in casing 1 first air inlet by shutter 4 by windproof sandbox, meet with dust board 3 again, sand and dust are dived downwards, laying dust plate 2 produces deposition, further filtration sand and dust, because air outlet is raised, the rough sand dirt in air-flow, by gravity damping, is difficult to pass through air outlet, therefore cold wind is by after windproof sandbox, and the rough sand dirt arriving air outlet just can greatly reduce; It is just less that preassembled transformer station chassis can arrange the sand and dust arriving box house after second air intake filters, thus under solving the larger situation of bad environments dust storm, photovoltaic transformer station, inversion room and the bad problem of integrated photovoltaic Inverter Station air intake.
