Abstract

The invention discloses a novel sound absorbing composite board used for a transformer station. The composite board comprises a composite board body, an aluminum fiber sound absorbing board, a fillingmaterial, a backboard, and side boards. The composite board body is formed by the aluminum fiber sound absorbing board, the filling material, and the backboard from outside to inside. Two sides of the composite board body are provided with the side boards. One end of the composite board body is provided with a limiting boss, and the other end of the composite board body is provided with a limiting groove matched with the limiting boss. The aluminum fiber sound absorbing board and a micropunch plate are used as basic materials of the novel sound absorbing composite board used for a transformerstation. The aluminum fiber board and the micropunch plate form a first layer resonating cavity. Themicropunch plate and a wall form a second layer resonating cavity. The first layer resonating cavity is filled with polyester fibers. The impedance double-resonance sound absorbing system can reinforce low frequency sound absorption performance, and can also expand high-efficiency sound absorptionfrequency bands, and is convenient to install.

Description

technical field [0001] The invention relates to the technical field of equipment related to sound-absorbing composite panels, in particular to a novel sound-absorbing composite panel for substations. Background technique [0002] Traditional microporous fiber composite sound-absorbing panels usually adopt the structural form of outer micro-perforated panels and inner aluminum fiber panels. This arrangement can give full play to the sound absorption performance of micro-perforated panels and porous fiber panels. While improving low-frequency sound absorption performance, Broadening the range of sound-absorbing frequency bands has better application value than traditional single-structure sound-absorbing materials, but this arrangement still cannot meet the deep noise reduction requirements of substation low-frequency noise. Contents of the invention [0003] The purpose of the present invention is to provide a new type of sound-absorbing composite panel for substation, whic...
