This invention discloses a low-frequency ventilation and noise reduction structure for a prefabricated substation, comprising a shell, multi-stage side-supported resonant sound absorbers, a main ventilation duct, a composite sound-absorbing layer, and a constrained damping layer. The shell has an air inlet and an air outlet. The main ventilation duct is formed inside the shell and runs through the airflow direction from the air inlet to the air outlet. The multi-stage side-supported resonant sound absorbers are located circumferentially or axially outside the main ventilation duct and are connected to the main ventilation duct through a neck channel. The composite sound-absorbing layer is located on the inner wall of the main ventilation duct, and the constrained damping layer is located on the inner side of the shell. Each stage of the side-supported resonant sound absorber has a different cavity volume, neck cross-sectional area, and equivalent neck length to absorb noise in different low-frequency bands. This invention, while maintaining the unobstructed ventilation and heat dissipation channels of the prefabricated substation, can achieve multi-peak coupling noise reduction for low-frequency noise in the 50~200Hz range, while also considering low voltage loss, compact structure, convenient installation, and adaptability to outdoor operation.
