Noise reduction double-sided sound absorption barrier for transformer

Abstract

The invention relates to a noise reduction double-sided sound absorption barrier for a transformer, which comprises an upper V-shaped part with an upward opening, a middle vertical part and a lower V-shaped part with a downward opening, wherein the upper V-shaped part and the lower V-shaped part are the same in structure and material, the left sides of the upper V-shaped part and the lower V-shaped part and the left side face of the middle vertical part face one transformer noise source, and the right sides of the upper V-shaped part and the lower V-shaped part and the right side face of the middle vertical part face the other transformer noise source. Based on the characteristic that the transformer generates noise frequency, the internal size of the sound absorption barrier is designed,noise propagated through the foundation and the underground after the transformer oil tank is connected with the foundation can be effectively reduced, the spread of noise in the air can be effectively reduced, the barrier is particularly suitable for noise reduction and absorption of a plurality of transformers which are arranged in a row, the structure is stable, the sound absorption efficiencyis high, sound absorption and noise reduction between two transformers can be carried out, the operation environment of the transformer can be improved, and effective support is made for an environment-friendly power grid.

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...

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
