Abstract
The invention relates to a power capacitor possessing a noise shield device. The power capacitor possessing a noise shield device comprises a power capacitor and a shell. A bottom of the shell is equipped with a bottom shielding layer. A shape of the bottom shielding layer matches with the shape of the shell bottom. A shell top is provided with a head cover shielding layer. The shape of the head cover shielding layer matches with the shape of the shell top. The bottom shielding layer is installed on the bottom out of the shell or the bottom in the shell. The head cover shielding layer is installed on the top out of the shell or the top in the shell. The bottom shielding layer and the head cover shielding layer are made of foamed aluminium. Materials of the bottom shielding layer and the head cover shielding layer are light and have characteristics of sound absorption and sound insulation, energy absorption and electronic shielding electromagnetic wave. A frequency spectrum scope of the absorbed noise is wide. Ventilation and heat dissipation of the power capacitor can not be influenced. A noise level of the power capacitor can be reduced. A structure is simple and compact. Installation and usage are convenient. A shielding effect is good. A service life is long. Usage costs are low. The power capacitor is safe and reliable.
Description
Technical field
The present invention relates to a kind of noise shielding device, 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
