[0015] Compared with the prior art, the invention has the following beneficial effects: the dry-type transformer with incoming line protection structure,

[0016] (1) In order to solve the problem that the existing dry-type transformer cannot protect the wires, so that the high-voltage wires are easy to fit with the low-voltage wires, thereby causing safety accidents, the present application is provided with an incoming line protection assembly and a protective top plate. Through the incoming line protection assembly, it is convenient to directional-enter the high-voltage wires and the low-voltage wires to avoid fitting and entanglement, and avoid safety accidents. At the same time, a protective top plate is provided to facilitate the protection of the incoming line protection assembly, thereby improving the protection of use;

However, when the dry-type transformer is transported on a flat surface, a lifting device is used for lifting and transportation, which wastes resources.
