Description
Technical field
The present invention relates to power engineering ventilation noise reduction technology field, particularly relate to the indoor substation noise control of 110kV city
Standard class processed is main transformer room when two grades.
Background technology
City is congregated district of population, and main transformer is all placed on indoor when standing in design by 110 kV urban transformations, logical
Cross house sound insulation and the running noises of shielding control main transformer, but because the safe operation of main transformer needs ventilation and heat, main
Transformer room must offer again door-window opening, causes the noise of indoor to reach outdoor, surrounding resident is produced impact.At city ring
Today that border noise control standard is the strictest, use new sound-deadening and noise-reducing measure to reduce transforming plant main transformer room noise and seem particularly
Important.
Summary of the invention
It is an object of the invention to the deficiency on the operation characteristic for existing unattended operation transformer station and noise control technique
Part, it is proposed that a kind of city indoor substation transformer chamber ventilation noise reduction system, on the premise of simple in construction and power consumption are relatively low,
Effectively reduce transformer chamber's outdoor noise.
To achieve these goals, the technical solution used in the present invention is:
A kind of city indoor substation transformer chamber ventilation noise reduction system, is included in transformer chamber and is provided with ventilating noise-elimination BAIYE, leading
Become upper end, room and be provided with vent, also include the fan house being arranged on transformer chamber top, fan house by vent directly with
Transformer chamber connects, and arranges blower fan, fan house wall is provided with air inlet and natural wind able to turn on or off in fan house
Exhaust outlet, is provided with impedance muffler at the fan outlet of blower fan, and impedance muffler is arranged on inside fan house,
Noise reduction elbow it is provided with at the air outlet of impedance muffler.
Also include protecting the intelligent wind control of main transformer indoor transformer to control device, measure the temperature of transformer temperature in transformer chamber
Degree sensor, intelligence wind control controller is according to the temperature set, and start and stop blower fan carries out temperature control, sets at natural wind exhaust outlet
Air-valve, air-valve linkage intelligence wind control is had to control device.
Also including acoustic-optic alarm, acoustic-optic alarm includes speaker and flash lamp, intelligence wind control controller according to
The temperature set, start and stop blower fan is carried out temperature control and is reported to the police by acoustic-optic alarm.
During described main transformer temperature >=45 DEG C, intelligence wind control controller controls blower fan and automatically turns on, and linkage air-valve cuts out；Main
During temperature ＜ 45 DEG C, blower fan is automatically switched off, and linkage air-valve is opened.
Transformer chamber and fan house indoor wall surface are laid with sound-absorbing material, and sound-absorbing material uses that barbed delthyrium is micro-to be worn
Orifice plate and aluminum fiber acoustic board composite plate.
The maintenance wicket for inspection maintenance at ordinary times is had on described ventilating noise reduction soundproof door.
The present invention, compared with traditional transforming plant main transformer chamber ventilated noise reduction technology, present invention solves the problem that one is
The cross-ventilation ventilating problem in transformer chamber under the conditions of normal working temperature；Two is that unattended operation transformer station is in transformer chamber's temperature
How in the case of not having personnel to operate in time, indoor temperature, properly functioning the asking of guarantee equipment is reduced when exceeding design temperature
Topic；After three are fan starting, how under conditions of positive mechanical is ventilated, by noise control in allowed band outside transformer chamber
Problem.The present invention, after using available ventilation and noise reduction measure, effectively meets while transformer chamber's room ventilation requirement significantly
Reduce outdoor noise.Show that outside transformer substation noise ＜ 50dB meets city through effective monitoring result of environmental monitoring part
Area two noise like controls the requirement of standard.
Accompanying drawing explanation
Fig. 1 is transformer chamber of the present invention and fan house generalized section；
Fig. 2 is roof ventilator room of the present invention floor map；
Fig. 3 is roof ventilator room of the present invention inner wall surface schematic diagram；
Fig. 4 is roof ventilator room of the present invention wall face schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described.
Embodiment
As shown in Fig. 1 ~ 4, the 110kV transformer chamber of the present embodiment and the city indoor substation main transformer of radiator chamber not split
The ventilation noise reduction system that room uses, including transformer chamber 1 and fan house 7；Ventilating noise-elimination BAIYE it is provided with on the downside of transformer chamber gate
2, indoor are provided with attemperating unit 3；Transformer chamber roof is provided with fan house 7, and fan house 7 inner blower 4 is eliminated the noise with impedance type
Device 5 is connected in series；Air inlet 11 and natural wind exhaust outlet 12 are set on fan house 7 interior wall, on natural wind exhaust outlet
It is provided with and the air-valve 8 of attemperating unit 3 linkage；Maintenance wicket 9, noise elimination ventilating blind 10 and fan outlet it is provided with on exterior wall
13；Fan outlet termination is provided with bend muffler 6.
The present invention method of operation under conventional sense is that blower fan 4 cuts out, and air-valve 8 is opened, by ventilating noise reduction BAIYE 2
Natural air inlet, air-valve 8 and ventilating noise reduction BAIYE 10 natural exhaust, generally natural ventilating status.Set when transformer chamber's temperature exceedes
During fixed temperature, attemperating unit 3 controls blower fan 4 and opens, and the air-valve 8 linked with it cuts out, and is naturally entered by ventilating noise reduction BAIYE 2
Wind, indoor high-temperature gas passes sequentially through blower fan 4, impedance muffler 5 and bend muffler 6, and room air is arranged by positive mechanical
Outside wind mode discharge chamber.
Because transformer chamber 1 and fan house 7 indoor wall are all laid with sound-absorbing material, can effectively absorb and propagate to body of wall
Indoor noise, main transformer room noise is mainly outwards propagated by shutter and wind passage mouth, is therefore entered these noise transmission approach
Row effectively controls, and both can reduce transformer chamber's outdoor noise.During natural ventilating status, at inlet and outlet, it is respectively provided with sound absorbing louver,
Effectively suppression noise outwards can be propagated；During positive mechanical ventilation state, linkage air-valve cuts out, and high-speed gas passes through blower fan, warp
Impedance muffler and bend muffler discharge, the noise that impedance muffler and bend muffler can effectively spread out of in filter chamber
The noise produced with elimination high velocity air, meets the requirement of criterion for noise control.
Patent of the present invention is after using available ventilation and noise reduction measure, while effectively meeting transformer chamber's room ventilation requirement
Significantly reduce outdoor noise.Show through effective monitoring result of environmental monitoring part, outside transformer substation noise ＜ 50dB, meet
Urban area two noise like controls the requirement of standard.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the simple change of those ordinary skill in the art
Within being all protection scope of the present invention with replacement.
