Abstract
The utility model discloses an epoxy resin dry-type power transformer, which relates to transformer manufacturing technology and belongs to field of electrotechology. The power transformer comprises an alloy iron core, high/low voltage combined winding and a bending-plate clamp. The high/low voltage combined winding winds the coil and is formed by wholly pouring of the epoxy resin; solvent-free gridding cloth is arranged at the inner layer and the outer layer and between layers of the high/low voltage combined winding, and the epoxy resin fully penetrates the coil. After the high/low voltage combined winding winds the coil and is formed by wholly pouring of the epoxy resign, a left side column and a right side column are clamped through the bending-plate clamp; an upper copper row and a lower copper row are tightened to lead the transformer to form a solid integrity; and sub-splicing sheets are arranged between the high voltage combined winding and the low voltage combined winding for further fixing. The benefits are as follows: the high/low voltage combined coil winding in the transformer is wholly formed by adopting epoxy resin pouring, improves field intensity inside the winding, increases the impact resistance and mechanical strength; the solvent-free gridding cloth is arranged at the inner layer and the outer layer and between layers of the soil winding, so as to lead greatly reduce PD capacity and extend the service life.
