Abstract

The embodiment of the invention discloses a transformer substation silencing wall. The transformer substation silencing wall comprises a silencing plate arranged close to the side of a transformer substation and a ventilation plate arranged far away from the side of the transformer substation, a noise reduction cavity is arranged between the silencing plate and the ventilation plate, an external silencing structure is arranged on the silencing plate, an opening structure in transmission connection with the external silencing structure is arranged in the noise reduction cavity, and an internalsilencing structure is arranged in the noise reduction cavity and close to the ventilation plate. Through the silencing wall formed by the ventilation plate and the silencing plate, sound is subjectedto primary noise reduction treatment through the external silencing structure arranged on the silencing plate, and then subjected to secondary noise reduction treatment through the internal silencingstructure arranged in the noise reduction cavity, so that the noise reduction effect of the silencing wall is improved, and the problem that the sound absorption effect is reduced due to the fact that a sound absorption material in a perforated board is prone to damp in the prior art is solved.

Description

technical field

[0001] The embodiment of the present invention relates to the technical field of sound-absorbing devices, in particular to a sound-absorbing wall of a substation. Background technique

[0002] Noise pollution has become one of the serious environmental problems in the process of urbanization in China. With the development of Chinese society, the country pays more and more attention to people-oriented, social harmony and scientific development, and pays more and more attention to the living environment of citizens. Acoustic environment quality control will be a major issue of sustainable development in the new century.

[0003] "Green power grid" and "green substation" will become the development direction of urban power grid and substation design and construction. It requires not only the splendor of the city and the protection of residents' electricity consumption, but also the comfort and harmony of the city and the tranquility of the residents. Therefore...
