This invention belongs to the field of transformer technology, specifically relating to a high-heat-dissipation protective transformer. It includes a transformer body, with two rows of bushings installed on the top of the transformer body, including one row of high-voltage bushings and one row of low-voltage bushings. A mesh cover is installed on the top of the transformer body, comprising a first mesh cover and a second mesh cover. The high-voltage bushings are all located within the first mesh cover, and the low-voltage bushings are all located within the second mesh cover. This invention provides comprehensive protection for the transformer while ensuring heat dissipation. It prevents corrosion from rainwater during rain, as rainwater is less likely to cause heat dissipation problems in the bushing area. In hot, windy environments, it ensures both protection and heat dissipation. This invention achieves optimal heat dissipation in hot, windless environments, reduces the risk of damage at bushing connections, and facilitates maintenance operations at the bushing connections.
