Transformer substation enclosing wall sound insulation device

Abstract

The invention discloses a transformer substation enclosing wall sound insulation device. The transformer substation enclosing wall sound insulation device comprises a sound insulation plate and a fixing frame; the fixing frame is of a frame structure made of a stainless steel material, the lower portion of the fixing frame is fixed to the vertical face of the inner side of a transformer substation enclosing wall through a plurality of expansion screws, and the upper portion of fixing frame is higher than the upper edge of the transformer substation enclosing wall; a frame on the upper portion of the fixing frame is of a hollow structure, and an insertion hole is formed in the top face of the fixing frame; the sound insulation plate is made of a transparent endurance plate, the lower portion of the sound insulation plate is inserted into the insertion hole of the fixing frame, the upper portion of the sound insulation plate is of a cambered surface structure which is bent towards the inner side of the transformer substation enclosing wall, and the radian of the cambered surface structure is pi / 4. According to the transformer substation enclosing wall sound insulation device, not only can the noise reducing purpose be achieved, but also installation of an anti-theft power grid is not hindered, the design is reasonable, operation is convenient, and resources are saved; in addition, by adopting the transparent endurance plate as the sound insulation plate, light in a transformer substation is not influenced; due to the fact that arc-shaped design is adopted on the upper portion of the sound insulation plate, the sound absorption area is increased, targeted shielding on noise in the transformer substation is achieved, and it is guaranteed that noise at the boundary of the transformer substation accords with relevant regulations.

Description

technical field [0001] The invention belongs to the technical field of substation protection, in particular to a sound insulation device for a substation wall. Background technique [0002] In recent years, with the development of the economy, the demand for electricity has increased rapidly, and a large number of substations have been built one after another. With the increase of power supply capacity and power supply area, and the change of substation form, ensuing environmental problems have become increasingly prominent. Among them, noise pollution is one of the most serious problems. In a substation, there are many noise-generating equipment, such as transformers, reactors, and ventilation equipment. At present, conventional noise reduction measures include optimizing equipment, optimizing layout, and raising walls. With the continuous increase of noise, the height of the wall is also increasing; in the process of increasing the height of the wall, there are often ph...

AI Technical Summary

Problems solved by technology

With the continuous increase of noise, the height of the fence is also increasing; in the process of increasing the height of the fence, there are often phenomena that do not meet the architectural design specifications, and even affect the layout of outgoing and incoming lines in the station and increase construction costs.
