Description
Technical field
The utility model relates to a kind of noise shielding device, and especially a kind of power capacitor with noise shielding device belongs to the technical field of power capacitor noise shielding.
Background technology
Along with the development of China's electric utility and the raising of people's environmental consciousness, how to reduce even the noise pollution of eliminating power capacitor has become a new problem.
Power capacitor noise abatement at present mainly relies on the increase screening arrangement.Screening arrangement is generally processed by special material, can absorb a certain frequency spectrum or a certain frequency range pectrum noise, thereby realizes reducing the purpose that whole device makes a noise.
But some noise shielding devices itself have defective, as: the noise spectrum narrow range that 1-absorbs, cause shield effectiveness not obvious; 2-influences the ventilation and the heat radiation of capacitor device; The accelerated ageing of being exposed to the weather easily of the outdoor noise shielding device of 3-; 4-noise shielding materials processing difficulty, cost is high.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of power capacitor with noise shielding device is provided, and it is simple and compact for structure, and is easy to install, and shield effectiveness is good, long service life, and use cost is low, and is safe and reliable.
According to the technical scheme that the utility model provides, said power capacitor with noise shielding device comprises the housing of power capacitor and said power capacitor; The bottom of said housing is provided with the bottom shield layer, and the shape of said bottom shield layer and housing bottom is complementary; The top of housing is provided with the top cover screen, and the end shape of top cover screen and housing is complementary.
Said bottom shield layer and top cover screen all adopt foamed aluminium to process.Said housing is provided with the binding post of symmetrical distribution corresponding to the top that the top cover screen is set.
Said top cover screen is provided with the installing and locating hole of symmetrical distribution, and said installing and locating hole is corresponding with binding post.
Said bottom shield layer is positioned at the outer bottom of housing, and the top cover screen is positioned at the outer top of housing.
Said bottom shield layer is positioned at the bottom of housing, and the top cover screen is positioned at the top of housing.
The advantage of the utility model: the housing two ends of power capacitor are provided with bottom shield layer and top cover screen, and the bottom shield layer is installed on outer bottom of housing or the bottom in the housing, and the top cover screen is installed on outer top of housing or the top in the housing; Bottom shield layer and top cover screen are all processed through foamed aluminium, and the material ultralight of bottom shield layer and top cover screen can the sound-absorbing sound insulation, the electromagnetic effect of energy-absorbing and electronic shield; The spectral range of absorption of noise is wide, and can not influence the ventilation and heat of power capacitor, can reduce the noise level of power capacitor; Simple and compact for structure, easy to install, shield effectiveness is good; Long service life, use cost is low, and is safe and reliable.
