Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, the noise-reduction heat-dissipation box-type substation comprises an inner cabinet body 4 composed of a high-pressure chamber 1, a transformer chamber 2 and a low-pressure chamber 3, wherein the transformer chamber 2 is positioned between the high-pressure chamber 1 and the low-pressure chamber 3, and is characterized in that a second step 7 and a first step 6 below the second step 7 are arranged below the inner cabinet body 4, a fan chamber 11 is arranged in the second step 7, a fan 12 and a sound-proof cover 13 outside the fan 12 are arranged in the fan chamber 11, the sound-proof cover 13 isolates and seals a sound source of noise, the distance between the wall surface of the sound-proof cover 13 and the fan chamber 11 is not less than 10 cm so as to reduce coupling resonance, the fan chamber 11 is further communicated with three air ducts 14, an outer cabinet body 5 is arranged outside the inner cabinet body 4, an air chamber 18 is formed between the inner cabinet body 4 and the outer cabinet body 5, one of the three air ducts 14 is communicated, an air outlet 15 is formed in the rear side wall of the outer cabinet body 5, the fan 12 blows air to three air channels 14 after working, the air blows upwards from the bottom in the transformer chamber 2 to have heat of a transformer main body, the air in the air chamber 18 flows along the outer wall of the inner cabinet body 4 to take away redundant heat on the inner cabinet body 4, and finally hot air is sent out from the air outlet 15, a wooden base plate 19 is fixedly arranged at the bottom of the transformer chamber 2, the wooden base plate 19 does not block the air channel 14 in the transformer chamber 2 from normally blowing out air, so that the wind energy is ensured to flow smoothly in the transformer chamber 2, the special fiber porous performance of the wood effectively plays a damping role on the transformer, and a temperature sensor 20 and an air window 17 are fixedly arranged on the side wall of the transformer chamber 2. A preset value is set for the temperature sensor 20, and when the temperature does not reach the preset value of the sensor, the fan 12 is in a shutdown state and radiates heat by means of all chambers of a natural ventilation team; only when the temperature rises to reach the preset value of the sensor, the fan 12 starts to work, the heat in the transformer substation is taken away through the air duct 14 and the air chamber 18, and the air duct 14 in the transformer chamber 2 independently supplies air and dissipates heat for the transformer chamber 2 with serious heat.
The inner cabinet body 4 is provided with cabinet doors corresponding to the high-voltage chamber 1, the transformer chamber 2 and the low-voltage chamber 3, the outer cabinet body 5 is in a semi-surrounding structure and is hermetically connected with the inner cabinet body 4, and the outer cabinet body 5 does not shield the cabinet doors. The outer cabinet body 5 surrounds the inner cabinet body 4 except for the cabinet door, the top and the bottom, so that the area of the air chamber 18 is increased as much as possible, and the cooling effect of the inner cabinet body 4 is enhanced.
The two air ducts 14 leading to the air chamber 18 open on one side of the low-pressure chamber 3 facing away from the transformer chamber 2 and on the other side of the high-pressure chamber 1 facing away from the transformer chamber 2. The air in the air chamber 18 is convected from the high pressure chamber 1 and the low pressure chamber 3 to accelerate the temperature reduction.
The screen plate 9 is installed at the opening of the fan room 11, the screen plate 9 is fixed through an internal fastener, a landslide 10 located below the fan room 11 is arranged on the first step 6, and the width of the landslide 10 is not smaller than that of the fan room 11. The landslide 10 is arranged for preventing rainwater from entering the fan room 11, and accumulated water is effectively evacuated.
And the air window 17 of the transformer chamber 2 corresponds to the air outlet 15 on the outer cabinet body 5. Wind blows from the bottom of the transformer room 2 to the wind windows 17 and is discharged from the air outlet 15 with the shortest distance.
The exhaust outlet 15 is fixedly provided with a silencing louver 16. The noise elimination louver 16 has a certain noise elimination effect, does not affect the flow of the air flow, and performs noise reduction processing again on the air blown out from the air outlet 15.
And a layer of microporous fiber composite sound absorption plate 21 is also adhered to the inner side of the outer cabinet. The noise of the transformer belongs to low-frequency noise, the low-frequency noise is difficult to eliminate only by the wood base plate 19 and the shutter 16, the low-frequency sound absorption coefficient of the microporous fiber composite sound absorption plate 21 is high, and the low-frequency noise of the transformer is effectively eliminated due to green and environment-friendly effects.
An inclined cabinet top 8 is further arranged above the outer cabinet body 5, and the cabinet top 8 is in sealing connection with the air chamber 18. The cabinet top 8 is hermetically connected with the air chamber 18, so that air cannot leak from the cabinet top 8 to reduce the heat dissipation efficiency, and the cabinet top 8 is inclined to disperse rainwater, so that rainwater is prevented from entering the inner cabinet body 4.
When the utility model is used, natural wind blows the air duct 14 to enter the air chamber 18 in the normal working state, the air in the air chamber 18 exchanges heat with the inner cabinet body 4 to take away the heat on the inner cabinet body 4 and is discharged from the air outlet 15, because the transformer generates much heat, an air duct 14 is independently established to lead to the transformer chamber 2, the high temperature in the transformer chamber 2 is output from the air window 17, and finally the high temperature is discharged from the air outlet 15 to achieve the purpose of heat dissipation; when natural wind cannot meet the heat dissipation requirement in the cabinet body, the temperature in the transformer room 2 rises to reach the preset value of the temperature sensor 20, and the fan 12 is started to enhance the wind speed and the air flow strength, so that the heat exchange efficiency is enhanced. It should be noted that the preset value of the temperature sensor 20 should be increased in hot summer to reduce mechanical loss and save energy.
The utility model has the advantages that: compared with the prior art, the novel air chamber ventilation and heat dissipation device has the innovation point of adopting air chambers to ventilate and dissipate heat, takes natural ventilation as main mechanical ventilation as assistance, combines multiple noise reduction means of the sound-proof cover, the noise-elimination shutter, the wooden base plate and the microporous fiber composite sound-absorbing plate, and has the advantages of scientific noise reduction, reasonable energy saving and heat dissipation.
