A noise reduction structure for a dry-type transformer
By introducing a vacuum-jacketed noise-reducing enclosure and a multi-layer spring telescopic rod connecting rod structure into the dry-type transformer, the problems of transformer swaying and noise were solved. At the same time, efficient noise reduction and heat dissipation were achieved by using a cooling fan and a dustproof net.

Abstract
This utility model relates to the field of transformer technology and discloses a noise reduction structure for dry-type transformers, including a noise reduction housing with two soundproof doors rotatably connected to its surface. In this noise reduction structure for dry-type transformers, when the transformer body shakes during operation, the support plate transmits the force to the first movable seat via a first connecting rod and simultaneously to the second movable seat via a second connecting rod. Under the action of the first and second spring telescopic rods, the transformer body is buffered, thereby reducing the noise generated by the shaking. Furthermore, the vacuum interlayer of the noise reduction housing enhances its noise reduction effect. Two cooling fans exhaust air from the top and sides of the noise reduction housing, creating a negative pressure inside. This allows air to enter the interior of the noise reduction housing through the cooling mechanism, thus achieving a cooling function.
