Waterproof device for dry-type transformer

The utility model relates to the technical field of dry-type transformers, in particular to a waterproof device of a dry-type transformer, which comprises a box body, a mounting mechanism, a plurality of flow guide mechanisms and a heat dissipation mechanism, a top cover is fixedly mounted at the top of the box body, the flow guide mechanisms are arranged on two sides of the top cover, and the box body is fixedly connected with the top cover through the mounting mechanism. And heat dissipation mechanisms are arranged outside the two sides of the box body, and each flow guide mechanism comprises a flow guide groove, a fixing block, a water accumulation groove and a water drainage pipe. Through the arrangement of the top cover, in rainy days, rainwater falls into the flow guide groove formed in the top of the top cover, flows into the water accumulation groove in the fixing block along the flow guide groove, then enters the drainage pipe through the water accumulation groove, and then is drained from the bottom
