Abstract
Disclosed is a transformer cabin ventilation and sound attenuation system which comprises a transformer cabin and a roof natural ventilator arranged at the top of the transformer cabin and communicated with the transformer cabin. An exterior wall air passage inlet communicated with an air channel in the transformer cabin is arranged on the exterior wall of the transformer cabin; an underground air channel inlet communicated with the transformer cabin is arranged at the bottom of the interior wall of the transformer cabin; blowers communicated with the exterior wall air channel inlet and the underground air channel inlet are arranged at all the four corners of the transformer cabin; the air outlets of the blowers face a radiator; and muffling shutters are arranged on the exterior wall air channel inlet, the underground air channel inlet and the outlet of the roof natural ventilator. The blowers of the ventilation and sound attenuation system are separately arranged, thus effectively adjusting the air distribution in the cabin, and since the system is provided muffling shutters, noise of the blowers is greatly reduced, reaching the requirement of urban environment noise standard. By adopting the roof natural ventilator for exhausting air naturally, the ventilation and sound attenuation system effectively reduces the energy consumption of the blowers; by making use of the exterior wall and the underground air channel for taking in air, the ventilation and sound attenuation system solves the difficulty that the ventilation exterior wall is small in area; and the air channel built underground has the effect of cooling the air.
Description
Technical field
The utility model relates to the ventilation of transformer room system, relate in particular to a kind of noise control have relatively high expectations the zone the ventilation of transformer room silene system.
Background technology
Transformer is one of nucleus equipment of transformer station, and whether its transformer station that is directly connected to whether working properly normally moves.Because transformer exists investment high, volume, weight are big, heat dissipation capacity is big, the noise height, oil reserve is big, fire risk grade height, but the ventilation outer wall bulk area is little, problems such as the ventilation difficulty is big will be resolved transformer and ventilate, and must take all factors into consideration from many-sides such as ventilation equipment type selecting, draft type selection and layouts.
The traditional draft type in transformer room generally adopts natural air inlet, mechanical exhaust or mechanical air intake, the draft type of natural exhaust, blower fan all adopts exterior wall or roof to install, indoor air flow tissue odds is even, summer, indoor environment temperature was much larger than the indoor design temperature, the ventilation equipment energy consumption is big, the noise height.
Along with rapid development of social economy, the improving constantly of living standards of the people, the augmentation day by day of electricity consumption channel, the increase of power load, having increasing transformer station needs in the down town and the surrounding area construction.These transformer stations must satisfy urban architecture and view is coordinated mutually, simultaneously, ventilate on the basis of satisfying the equipment operating environment temperature requirement, must satisfy the requirement of urban area environmental noise standard.And that existing ventilation of transformer room system airflow is organized is not smooth, and summer, indoor temperature was too high, and transformer and ventilation equipment noise are all influential to surrounding enviroment simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of energy consumption that can reduce ventilating system is provided, and can reduce the ventilation of transformer room silene system of noise simultaneously again.
For achieving the above object, the technical solution adopted in the utility model is: the coupled logical roof natural ventilation that comprises the transformer room and be opened in the top, transformer room, on the exterior wall of transformer room, offer the exterior wall air channel inlet that is connected with air channel in the transformer room, offer the underground air duct inlet that is connected with the transformer room in the bottom of transformer room, and four jiaos in the transformer room are provided with the blower fan that is connected with exterior wall air channel inlet and underground air duct inlet, the air outlet of this blower fan is over against radiator, and enters the mouth in the exterior wall air channel, the exit position of underground air duct inlet and roof natural ventilation is provided with the noise reduction blinds.
Blower fan of the present utility model adopts axial flow blower.
Because the utility model ventilation of transformer room silene system is reasonable in design, the blower fan dispersed placement has effectively been regulated the indoor air flow tissue, greatly reduces fan energy consumption and noise; Blower fan, air channel inlet and roof natural ventilation are provided with the noise reduction blinds, make noise satisfy the requirement of urban area environmental noise standard; Utilize underground air duct and exterior wall two parts air intake, solved the little difficulty of ventilation outer wall area, and the air channel, hypogee there is the effect that cools to wind.
Description of drawings
Fig. 1 is a floor map of the present utility model;
Fig. 2 is the utility model profile.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1,2, the coupled logical roof natural ventilation 7 that the utility model comprises transformer room 4 and is opened in 4 tops, transformer room, on the exterior wall of transformer room 4, offer the exterior wall air channel inlet 5-1 that is connected with air channel 3 in the transformer room 4,4 bottom offers the underground air duct inlet 5 that is connected with transformer room 4 in the transformer room, and 4 four jiaos are provided with and exterior wall air channel inlet 5-1 and underground air duct inlet 5 axial flow blowers that are connected 1 in the transformer room, the air outlet of this blower fan 1 is over against radiator 6, and at exterior wall air channel inlet 5-1, the exit position of underground air duct inlet 5 and roof natural ventilation 7 is provided with noise reduction blinds 2.
The utility model ventilation of transformer room silene system mainly comprises ventilating system and silene system, and ventilating system adopts the draft type of mechanical air intake, roof natural ventilation natural exhaust.Because main transformer room exterior wall incoming air area is limited, and indoor air flow organizes not freely, so employing two parts air intake, a part directly enters underground air duct 3 from noise reduction blinds 2, and blower fan 1 is evenly delivered to radiator 6 lower positions from underground air duct 3 air draughts with new wind; Another part adopts exterior wall noise reduction blinds air inlet system, and promptly wind enters the air channel through exterior wall noise reduction blinds 2, and blower fan 1 is evenly delivered to the radiator lower position from the air channel air draught with new wind.After sending into the new wind of radiator 6 bottoms and radiator 6 and fully carrying out heat exchange, because the effect of hot pressing and indoor forced draft, hot blast rises along radiator, after top noise reduction blinds, discharges outdoor from the top natural ventilator.Because each transformer room's air intake adopts 4 typhoon machine parallel runnings, effectively regulated indoor air flow, fan energy consumption has reduced by 40% when selecting 1 typhoon machine for use at least, noise has reduced 25dB (A) at least when selecting 1 typhoon machine for use, control flexible, when spring, autumn transition season outdoor temperature are low, adopt the air-supply of 2 typhoon machines.Blower fan, air channel suction inlet and roof natural ventilation aditus laryngis are equipped with the noise reduction blinds, make noise satisfy the requirement of urban area environmental noise standard.
Although in conjunction with the accompanying drawings preferred enforcement of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; the conventional design personnel of this area are under the enlightenment of utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms.
