Abstract

This invention relates to the field of dry-type transformer equipment technology. It discloses a quick-assembly integrated sound insulation and heat dissipation device for dry-type transformers, comprising a transformer body, an assembled sound insulation shell, a pull-out heat dissipation unit, heat sinks, and a flow guide plate. The assembled sound insulation shell is detachably fitted onto the outside of the transformer body, using multiple sound insulation panels spliced ​​together and equipped with sealing strips. The pull-out heat dissipation unit is connected to the side wall of the sound insulation shell and can be moved vertically for easy maintenance; it includes drive, translation, and reinforcement components. The heat sinks are corrugated and fixed to the inclined flow guide plate, which guides airflow and prevents dust. This device integrates sound insulation and heat dissipation, is easy to assemble, and highly efficient to maintain. It can be flexibly adapted to different specifications of dry-type transformers, ensuring equipment operational stability and service life.
