The central layer of the porous material of described sound insulationg board has the effect of buffering vibration, absorption of noise.Can effectively stop and absorb the noise that each capacitor unit produces, thereby reduce the noise that capacitor device produces in running.
Because of the sound insulationg board two sides is covered with metallic plate, is surrounded by the hard section bar all around,, good weatherability is arranged, and corrosion resistance is strong so can stand washing away of air-flow and current in the harsh weather.Its structure also makes it light weight, intensity height, good processability.
The sound insulationg board that stationary arrangement is installed between two row's capacitor unit bottom surfaces on one deck frame is 1 or 2.To strengthen defening effect.Have at least 2 fixed strips to be connected and installed in 2 sound insulationg boards between the capacitor unit bottom surface, stable to guarantee sound insulationg board.
The advantage that the utility model reduces the capacitor device of noise is: 1, be applicable to high-voltage electric power system, reduced the noise that produces in the capacitor device running effectively; 2, the sound insulationg board of installing on the capacitor device need not additionally to take the fabricating yard, and is easy to install and use; 3, sound insulationg board light weight, intensity height are corrosion-resistant good with weather resistance; 4, sound insulationg board does not influence the heat dispersion of device substantially; 5, simple in structure, cost is lower, be easy to promote the use of.
