The embodiment of the invention discloses a transformer substation silencing wall. The transformer substation silencing wall comprises a silencing plate arranged close to the side of a transformer substation and a ventilation plate arranged far away from the side of the transformer substation, a noise reduction cavity is arranged between the silencing plate and the ventilation plate, an external silencing structure is arranged on the silencing plate, an opening structure in transmission connection with the external silencing structure is arranged in the noise reduction cavity, and an internalsilencing structure is arranged in the noise reduction cavity and close to the ventilation plate. Through the silencing wall formed by the ventilation plate and the silencing plate, sound is subjectedto primary noise reduction treatment through the external silencing structure arranged on the silencing plate, and then subjected to secondary noise reduction treatment through the internal silencingstructure arranged in the noise reduction cavity, so that the noise reduction effect of the silencing wall is improved, and the problem that the sound absorption effect is reduced due to the fact that a sound absorption material in a perforated board is prone to damp in the prior art is solved.
本发明实施例公开了一种变电站消音墙，包括靠近变电站一侧设置的消音板以及远离变电站一侧设置的通气板，所述消音板与所述通气板之间设置有降噪空腔，所述消音板上设置有外消音结构，所述降噪空腔内设置有与所述外消音结构传动连接的张开结构，所述降噪空腔内靠近所述通气板设置有内消音结构，通过通气板以及消音板组合形成的消音墙在声音经过消音板上设置的外消音结构进行一次降噪处理，然后再通过降噪空腔内设置的内消音结构进行二次消音处理，提高消音墙的消音降噪的效果，以解决现有技术中由于穿孔板内吸声材料易受潮而导致的吸声效果下降的问题。
