Problems solved by technology

[0004] At present, many sound barriers are basically for sound insulation of a certain transformer, and it is rare to carry out sound insulation for two transformers at the same time
And the effect is mainly on the air noise generated by the transformer, but for the micro-vibration transmitted from the transformer to the foundation, through the structure to the upper part, and then to generate structural noise, it seems somewhat powerless

Embodiment 1

[0048] as attached figure 1 , 2 , 4, the present invention includes an upper V-shaped portion with an upward opening, a middle upright portion and a lower V-shaped portion with an opening downward, and the upper V-shaped portion, the middle upright portion and the lower V-shaped portion with an opening downward can be divided into There are two left and right parts, and the upper V-shaped part and the lower V-shaped part have the same structure and material. The left sides of the upper and lower vees and the left side of the middle upright face one transformer noise source, and the right sides of the upper and lower vees and the right side of the middle upright face the other transformer noise source.

[0049] The left side plate of the upper V-shaped part includes the front orifice plate 1, the front sound-absorbing layer 2 and the front thin steel plate 3 arranged in sequence from left to right, and the right side plate of the upper V-shaped part includes the rear plate ar...

Embodiment 2

[0057] The structure of this embodiment is consistent with that of Embodiment 1, and on the basis of Embodiment 1, a process connector 4 for connecting the upper V-shaped part, the middle upright part and the lower V-shaped part is added.

[0058] This embodiment includes all the technical features of Embodiment 1, that is, as attached figure 1 As shown, the present invention includes an upper V-shaped portion with an upward opening, a middle upright portion, and a lower V-shaped portion with an opening downward. The two parts, the upper V-shaped part and the lower V-shaped part have the same structure and material. The left sides of the upper and lower vees and the left side of the middle upright face one transformer noise source, and the right sides of the upper and lower vees and the right side of the middle upright face the other transformer noise source.

[0059] The left side plate of the upper V-shaped part includes the front orifice plate 1, the front sound-absorbing...

Abstract

The invention relates to a noise-reducing double-sided sound-absorbing barrier for a transformer, which comprises an upper V-shaped portion with an upward opening, a middle upright portion, and a lower V-shaped portion with an opening downward. The structures of the upper V-shaped portion and the lower V-shaped portion are the same Same material, left side of upper and lower vee and left side of middle upright facing a transformer noise source, right side of upper and lower vee and right side of middle upright facing Another transformer noise source; the present invention designs the internal size of the sound-absorbing barrier based on the characteristics of the noise frequency generated by the transformer, which can effectively reduce the noise transmitted through the foundation and underground after the transformer oil tank is connected to the foundation, and can also effectively reduce the noise in the air. Spreading to a distance, it is especially suitable for noise reduction and sound absorption of multiple transformers arranged in rows. provide effective support.

Description

technical field [0001] The invention belongs to the technical field of noise control, in particular to a noise-reducing double-sided sound-absorbing barrier for transformers. Background technique [0002] With the simultaneous rapid advancement of power grid construction and urban development, many substations will inevitably be built in urban centers or densely populated areas. Transformers, the main electrical equipment of substations, will produce noises of different sizes during normal operation. If these noises are not controlled and eliminated, they will seriously affect the lives and rest of nearby residents. [0003] There are three main modes of transformer noise transmission: one is that after the oil tank is connected to the foundation, the low-frequency noise of the transformer propagates through the ground; Spread through the surrounding air. Taking noise reduction measures in the way of transformer noise transmission has been continuously developed with the i...
