Problems solved by technology
[0002] At present, in order to reduce the noise of the main transformer, substations in urban areas far from residential areas often adopt indoor layouts. The building volume increases, and it is difficult to deal with ventilation and heat dissipation of the main transformer. The project cost is high, and the design and construction are difficult.

Embodiment Construction
[0011] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0012] A sound-absorbing sound barrier for the main transformer, such as figure 1 As shown, it includes: a transformer 4, the outside of the transformer 4 has a fire-retaining wall 3, the outside of the fire-retaining wall 3 is a partition wall 1, and the outside of the fire-retaining wall 3 is fixedly equipped with a sound-absorbing panel 2.
[0013] In this embodiment, the height of the sound-absorbing panel 2 from the ground is 1 meter.
[0014] Beneficial effects of the present invention: In the semi-indoor substation of the present invention, the main transformers are only separated by fire-retaining walls, and the sound-absorbing sound barrier is used to partially shield the main transformers, which has better feasibility, economy and effect. High-efficiency sound-absorbing centrifugal glass wool board is used as the material of sound insulati...

A main transformer sound absorption type sound barrier comprises a transformer. A fire barrier is arranged on the outer side of the transformer. A separating barrier is arranged on the outer side of the fire barrier. A sound absorption plate is fixedly installed on the outer side of the fire barrier. The height from the sound absorption plate to the ground is one meter. The main transformer sound absorption type sound barrier has the advantages that only the fire barrier is used for separating a half-indoor transformer substation from the main transformer, the sound absorption type sound barrier is adopted for shielding part of the main transformer and good in feasibility, economy and effect. The sound absorption type sound barrier is made of efficient sound absorption centrifugal glass wool boards, and therefore the sound absorption type sound barrier is good in noise reduction effect and performance, safe and reliable in structure, economical in material price, low in installation cost, durable in use, long in service life, harmonious in scenery and elegant in appearance.
Description
technical field [0001] The invention relates to a barrier for reducing transformer noise, in particular to a sound-absorbing sound barrier for a main transformer. Background technique [0002] At present, in order to reduce the noise of the main transformer, substations in urban areas far from residential areas often adopt indoor layouts. The building volume increases, and the ventilation and heat dissipation of the main transformer is difficult. The project cost is high, and the design and construction are difficult. Contents of the invention [0003] The object of the present invention is to provide a main transformer sound-absorbing sound barrier that can effectively reduce transformer noise. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A sound-absorbing sound barrier for a main transformer, comprising: a transformer, a fire-retaining wall outside the transformer, and an isolation wall outside the fire-retai...
