Technical field
The utility model belongs to denoising device technical field, and specifically, the utility model relates to a kind of bottom acoustic hood for dry reactor, particularly a kind of bottom acoustic hood for dry-type air-core reactor.
Background technology
In current conversion station, because converter valve can produce a large amount of harmonic currents in rectification and reversals, if can the quality of power supply be had a strong impact in inflow system, so need to adopt a series of filter to be carried out filtering.When the harmonic current of multiple frequency range is by dry reactor, produces multifrequency vibration, thus result in the audible noise of middle and high frequency range.Although fundamental current is greater than individual harmonic current, contribute to current conversion station overall noise with high-frequency noises.As long as therefore adopt an effective measure to high-frequency noises, its noise radiation power just significantly can be suppressed.
But, there is not the sound arrester directly reducing dry-type air-core reactor noise floor in prior art.
Utility model content
The purpose of this utility model is to provide a kind of bottom acoustic hood for dry reactor, with the technical problem that the dry reactor noise floor solving prior art existence is excessive.
In order to solve the problem, the utility model provides a kind of bottom acoustic hood for dry reactor, and its technical scheme is as follows:
For a bottom acoustic hood for dry reactor, described bottom acoustic hood is circle cap-like structure; Have ventilation hole in the bottom dead center position of described bottom acoustic hood, discharge for the thermal current that described dry reactor is distributed; In described bottom, acoustic hood has multiple through hole, and described bottom acoustic hood is fixedly mounted on the bottom of described dry reactor by the end of described dry reactor through described through hole every transition bearing.
Preferably, described bottom acoustic hood has multiple bolt hole, described spiro keyhole position is in the both sides of described through hole, and described bottom acoustic hood is fixed on described dry reactor by bolt hole by bolt.
Preferably, in the acoustic hood of described bottom, described through hole is square opening.
Preferably, the diameter of described bottom acoustic hood is greater than the diameter of described dry reactor, described bottom acoustic hood has multiple tracks and stretches out groove, stretches out for the line-outgoing arm of described dry reactor and nameplate arm.
Preferably, in the acoustic hood of described bottom, also comprise acoustical cotton, described acoustical cotton is arranged on the madial wall place of described bottom acoustic hood.
Preferably, described bottom acoustic hood is that fiber glass epoxy material makes.
Preferably, in the acoustic hood of described bottom, described dry reactor is dry-type air-core reactor.
Analyze known, compared with prior art, the bottom acoustic hood that the utility model provides is developed according to the noise behavior of dry-type air-core reactor just, and himself mechanism makes sound wave oscillatory extinction in the acoustic hood of bottom, reduces the noise level of dry-type air-core reactor.The agent structure of the bottom acoustic hood that the utility model provides is acoustic hood bottom fiberglass, and bottom fiberglass, acoustic hood and dry-type air-core reactor were connected to a fixed every transition bearing the end of by.Bottom this, the own form of acoustic hood and architectural feature determine it and have good noise reduction performance for the dry-type air-core reactor loading a large amount of harmonic wave, especially can effectively suppress for high-frequency noises radiant power, simultaneously, according to the supporting making of the dry-type air-core reactor of different model, can meet various installation requirements.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is bottom acoustic hood and dry reactor connection diagram.
In figure, acoustic hood bottom 1-; 2-ventilation hole; 3-through hole; 4-bolt hole; 5-stretches out groove; 6-dry reactor; Every transition bearing at the bottom of 61-; 62-nameplate arm; 63-line-outgoing arm.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 and Figure 2, the bottom acoustic hood 1 of preferred embodiment of the present utility model is circle cap-like structure, have ventilation hole 2 in the bottom dead center position of bottom acoustic hood 1, discharge, to ensure that the temperature rise of dry reactor 6 is in safe range for the thermal current that dry reactor 6 is distributed; Have multiple through hole 3 at bottom acoustic hood 1, bottom acoustic hood 1 is fixedly mounted on the bottom of dry reactor 6 by the end of dry reactor 6 through through hole 3 every transition bearing 61.The size of bottom acoustic hood 1 can adjust according to the size of dry reactor 6, and bottom acoustic hood 1 is as a whole.The size relationship of ventilation hole 2 is to air-flow turnover amount, thus directly affect the temperature rise of dry reactor 6, therefore, for the dry reactor 6 of different size, size, the size of ventilation hole 2 is determined by the calculating of careful throughput and temperature rise, thus ensure under the prerequisite not affecting good noise reduction, reduce the temperature rise of dry reactor 6 to greatest extent; Position of opening for through hole 3 is consistent every the Support Position of transition bearing 61 end of with, and the size of through hole 3 and the end close every the matching size of transition bearing 61, ensures that bottom acoustic hood 1 can pass the end and be arranged on the end on transition bearing 61 every transition bearing 61.
In order to can by the bottom being fixed on dry reactor 6 firm for bottom acoustic hood 1, bottom acoustic hood 1 has multiple bolt hole 4, bolt hole 4 is positioned at the both sides of through hole 3, and bottom acoustic hood 1 is fixed on dry reactor 6 by bolt hole 4 by bolt (not shown).When installation process, be connected every transition bearing 61 end of with by bolt, play the effect of installing solid bottom acoustic hood 1.Preferably, the center of through hole 3 and bolt hole 4 be centrally located on same circumference; The position of the bolt hole that the position of opening of bolt hole 4 and size and the end open on the fixing bent angle of transition bearing 61 and size match, and ensure the smooth installation of bottom acoustic hood 1 and dry reactor 6.Further preferably, through hole 3 is processed as square opening, to adapt every transition bearing 61 with the end of dry reactor 6.The size of through hole 3 and the end, close every the matching size of transition bearing 61.
In order to effectively play Noise Reduction, the diameter of bottom acoustic hood 1 is greater than the diameter of dry reactor 6; After dry reactor 6 is wrapped up, as shown in Figure 2, conveniently the nameplate arm 62 of dry reactor 6 and line-outgoing arm 63 stretch out, and bottom acoustic hood 1 has multiple tracks and stretches out groove 5, to stretch out be connected with outside for the nameplate arm 62 of dry reactor 6 with line-outgoing arm 63.The design of stretching out groove 5, while playing good noise reduction, does not affect using and checking of line-outgoing arm 63 and nameplate arm 62, and the degree of depth of stretching out groove 5 can be determined according to line-outgoing arm 63 and the width of nameplate arm 62 and the installation site of bottom acoustic hood 1.
In order to reach the effect of noise reduction better, the utility model also comprises acoustical cotton (not shown), and acoustical cotton is arranged on the madial wall place of bottom acoustic hood 1, specifically can require to install acoustical cotton according to noise reduction.
