Abstract
The utility model discloses a noise-and-magnetism-reducing system for a main transformer room. The system comprises the main transformer room which is fixedly provided with a fan; an air outlet of the main transformer room is fixedly provided with a silencing shutter; an inlet and an outlet of the main transformer room are hinged with sound insulation doors, and silencing ventilation windows are arranged at the bottom of the sound insulation doors; metal sound absorption wallboards are fixedly arranged on internal walls of the main transformer room except the sound insulation doors; the lower ends of the sound absorption wallboards are grounded; and a silencer is fixedly connected to an air discharge pipe of the fan. The system has an obvious effect of reducing the noises and electromagnetic radiation of the main transformer room and has high economic benefit.
Description
Technical field
The utility model relates to a kind of noise reduction demagnetize system, particularly a kind of noise reduction demagnetize system that is used in main transformer room.
Background technology
In recent years, along with the development of urban construction, a large amount of transformer stations that build are to satisfy the demand of urban economy development to electric power in the city.But noise is bigger during the work of substation transformer chamber; Particularly during the peak load in summer; Noise of transformer is more serious to the influence of the operate as normal life generation of surrounding resident; And produce stronger electromagnetic radiation in the transformer course of work, to electric equipment and the healthy influence and the injury that possibly cause in various degree of resident on every side.And existing equipment often all is to realize reducing noise or weaken electromagnetic radiation, not comparatively comprehensively protective shielding effect, and function ratio is more single.
The utility model content
For solving the deficiency of prior art, the utility model provides a kind of system that has noise reduction and demagnetize concurrently.
The utility model technical scheme that adopts of dealing with problems is:
A kind of noise reduction demagnetize system that is used for main transformer room; Comprise the main transformer room that is installed with blower fan; Said main transformer room air outlet is installed with the noise elimination blinds, and said main transformer room import and export are hinged with the soundproof door that the bottom is provided with the noise elimination ventilating window, is installed with metal sound absorption wallboard on the wall around the main transformer chamber interior beyond the said soundproof door; Said sound absorption wallboard lower end ground connection is fixedly connected with muffler on the said blower fan discharge pipe.
Further, said sound absorption wallboard is spliced by polylith metal piercing acoustic board, and said acoustic board jointing positions is provided with press strip.Press strip can be connected to an integral body with acoustic board, strengthens the effect of noise reduction demagnetize.
Further, said muffler air outlet also is fixedly connected with bend muffler.
Further, said main transformer room also is provided with air inlet, and said air inlet is installed with the noise elimination blinds.
The beneficial effect of the utility model: the utility model is provided with noise elimination blinds, soundproof door and muffler respectively at main transformer room inlet and outlet, import and export and fan outlet, blocks the path that noise is propagated outward, weakens noise; The sound absorption wallboard is installed around the main transformer chamber interior; Further reduce noise, on sound absorption wallboard seaming position, press strip is set simultaneously and, can better the sound absorption wallboard be connected into an integral body the acoustic wall plate earthing; Indoor, play the demagnetize effect to ELECTROMAGNETIC RADIATION SHIELDING.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is that the utility model is arranged sketch map;
Fig. 2 is the layout sketch map of the utility model fan house;
Fig. 3 is the structural representation of the utility model soundproof door;
Fig. 4 is the structural representation of the utility model sound absorption wallboard.
Embodiment
Like Fig. 1,2, a kind of noise reduction demagnetize system that is used for main transformer room shown in 3 and 4; Comprise the main transformer room 5 that is installed with blower fan 6; Said main transformer room 5 air outlets and air inlet are installed with noise elimination blinds 1 respectively, and it is hinged that said main transformer room 5 import and export and bottom are provided with the soundproof door 3 of noise elimination ventilating window 4, are installed with metal sound absorption wallboard 2 on the walls around main transformer room beyond the soundproof door 35 is inner; Sound absorption wallboard 2 lower end ground connection; Realize the effect of electromagnetic radiation shielding, sound absorption wallboard 2 is spliced by polylith metal piercing acoustic board 9, and said acoustic board 9 jointing positions are provided with press strip 10; Press strip better connects into integral body with acoustic board 9, improves noise reduction demagnetize effect.Be fixedly connected with muffler 7 on said blower fan 6 discharge pipes, muffler 7 air outlets also are fixedly connected with bend muffler 8.
During work, eliminated the noise blinds 1, soundproof door 3 and sound absorption wallboard 2 of the noise overwhelming majority that main transformer produces absorbs, and reduces noise and passes to outdoor amplitude; The noise that blower fan 6 produces weakens with bend muffler 8 through the muffler 7 that installs additional; The radiation that main transformer produces is then mainly shielded by the metal of lower end ground connection sound absorption wallboard 2, weakens the energy toward outdoor propagation.
The above is the utility model preferred implementation, and it does not constitute the restriction to the utility model protection range, so long as realize that with essentially identical means the purpose of the utility model all should belong to the protection range of the utility model.
