Sound absorption and insulation unit structure and modular sound absorption and insulation wall of transformer substation

Abstract

The invention provides a sound absorption and insulation unit structure and a transformer substation modular sound absorption and insulation wall. The sound absorption and insulation unit structure comprises a shell, a noise isolation mechanism arranged in the shell, a noise absorption mechanism and a noise inlet structure arranged on the shell. The noise isolation mechanism is of a plate-shaped structure matched with the shell structure, and the periphery of the plate-shaped structure is connected with the inner wall of the shell through the multiple noise absorption mechanisms. And a certain gap is formed between the plate-shaped structure and the shell. The sound absorption and insulation unit structure and the modular sound absorption and insulation wall of the transformer substation are excellent in sound absorption and insulation effect, the noise radiation level of the modular transformer substation is reduced in a limited mode, and sustainable and healthy development of the noise environment of the transformer substation is achieved.

Description

technical field [0001] The invention relates to the technical field of power grid environmental protection, in particular to a sound-absorbing and insulating unit structure and a substation modular sound-absorbing and insulating wall. Background technique [0002] The modular construction of 35kV~220kV smart substations has become the mainstream of infrastructure project design. The unified design depth and construction standards have improved construction efficiency and reduced construction costs. This type of substation generally adopts a prefabricated steel structure building, and the enclosure wall of the substation building is mostly made of light-weight walls such as aluminum-magnesium sandwich panels, which have very limited ability to control the noise of power equipment. Power transformers are the main noise source of substations. A large number of field tests and experimental studies have shown that transformer noise is medium and low frequency noise, and its spect...

Problems solved by technology

The interior and exterior wall materials currently used in modular substations are light, weather-resistant, stable, and environmentally friendly new materials. They are mainly designed from the perspective of energy conservation and fire prevention, and meet relevant performance indicators. However, there is no in-depth design and material selection in terms of wall acoustic performance.
