摘要： A dry-type transformer with an elliptical iron core includes a transformer housing, a heat dissipation mechanism, an elliptical iron core, a coil, a clamping mechanism and an upper cover. The heat dissipation mechanism is arranged in a horizontal direction and fixedly assembled with the transformer housing. One end, away from the transformer housing, of the heat dissipation mechanism is in contact with ground. The elliptical iron core is arranged in a vertical direction inside the transformer housing. The coil is wound on the elliptical iron core. The clamping mechanism is sheathed on one side, away from the elliptical iron core, of the coil. The upper cover is arranged at a top end of the transformer housing, and the upper cover is fixedly assembled with the transformer housing via a bolt structure.
