Evaporative cooling distribution transformer with novel cooling structure based on phase-change medium

The utility model discloses an evaporative cooling distribution transformer of a novel cooling structure based on a phase change medium. Wherein the box body internally comprises a soaking space and asteam condensation space; the soaking space is used for accommodating a transformer body and can be covered by a liquid insulating cooling medium with a phase change characteristic; the steam condensation space is positioned above the soaking space, is used for insulating other devices after the insulating cooling medium is evaporated, and can be condensed to flow back to the soaking space; wherein the other devices are located above the transformer body and are electrically connected with the transformer body. Through the implementation of the utility model, the structure is simple, self-circulation of evaporation, condensation and evaporation of an insulating cooling medium can be realized; the heat of the transformer is effectively dissipated; meanwhile, the use amount of an insulatingcooling medium is reduced
