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.

摘要： The present disclosure discloses a dry-type transformer with an elliptical iron core, comprising a transformer housing, a heat dissipation mechanism, an elliptical iron core, a coil, a clamping mechanism and an upper cover, the heat dissipation mechanism being arranged in a horizontal direction and fixedly assembled with the transformer housing, one end, away from the transformer housing, of the heat dissipation mechanism being in contact with ground, the elliptical iron core being arranged in a vertical direction inside the transformer housing, the coil being wound on the elliptical iron core, the clamping mechanism being sheathed on one side, away from the elliptical iron core, of the coil, the upper cover being arranged at a top end of the transformer housing, and the upper cover being fixedly assembled with the transformer housing via a bolt structure. The present disclosure uses an iron core with an elliptical cross section, wherein three-phase iron cores are arranged in a regular triangle shape and are respectively located at each midpoint position of edges of the triangle, and a winding manner of coil adjacent to the iron core is also different. In addition, a clamping mechanism is provided in the present disclosure, so that it is possible to implement a remedy for re-detachment of the coil during clamping, thereby extending a service life of the dry-type transformer.
