Since people go out during the day, the noise reduction requirements of the substation are not high. At night, the temperature is low, so the heat dissipation requirements of the substation are not high, but the noise reduction requirements for people who are resting are high. Therefore, it is urgent to design a built-in noise reduction device for the substation to solve the above problems. Utility Model Content

At night, the electric telescopic rod 11 pushes the sound insulation board 9 to be carded into the card slot 10, so that the transformer substation is more sealed, and heat is dissipated through a ventilation mechanism 17, thereby reducing the generation of noise, and at the same time increasing the sound insulation of the transformer substation and improving the noise reduction effect. During the day, the electric telescopic rod 11 contracts, and heat is dissipated to the transformer substation through a ventilation mechanism 3, so that the transformer substation is in a better heat dissipation environment.
