Abstract

The invention provides an air-cooling three-phase oil-immersed distribution transformer. The air-cooling three-phase oil-immersed distribution transformer comprises a transformer body. The transformer body comprises an oil box. The oil box is filled with high temperature resistant insulating oil. A transformer core is installed in the oil box, and the transformer core is immersed in the high temperature resistant insulating oil. At least one side wall of the oil box is communicated with a ripple tank. One side of the ripple tank is provided with a cooling fan of the ripple tank. The air outlet of the cooling fan of the ripple tank faces to the interior of the oil box. The provided air-cooling three-phase oil-immersed distribution transformer is capable of, through the cooling fan installed under the ripple tank, improving the cooling rate of the high temperature resistant insulating oil in the ripple tank, and further improving the heat-radiating cooling efficiency of the transformer through a cooling fan installed on the side face of the oil box. In addition, the back face of the cooling fan of the oil box is further provided with a self-cooling grating convenient for the self-cooling of the cooling fan of the oil box.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an air-cooled three-phase oil-immersed distribution transformer with improved heat dissipation performance. Background technique [0002] Transformer is an important equipment in power generation, power supply and power consumption enterprises. It is also in a very critical position in the power grid. It is an important device to ensure the safe and reliable operation of the power grid and the electrodes used by people in production and life.
