Cooling mechanism for dry-type transformer and cooling working method

Abstract

The invention discloses a cooling mechanism for a dry-type transformer, and the mechanism is arranged on a main box body, wherein the dry-type transformer is arranged in the main box body, and the cooling mechanism comprises a cooling box, a cooling assembly and an air supply bustle pipe; the cooling box is arranged on the outer side of the main box body, and the top of the cooling box communicates with the side wall of the top of the main box body through an air pipeline. The bottom of the cooling box communicates with the air supply bustle pipe through an air pipeline. The cooling assembly is installed on the cooling box and cools flowing air passing through the cooling box. The air supply bustle pipe is arranged on a bottom plate in the main box body, the air supply bustle pipe is arranged around a base of the dry-type transformer, and the inner side of the air supply bustle pipe can convey cooled flowing air to the dry-type transformer. The invention further provides a cooling working method applying the mechanism, heat generated by the dry-type transformer is conveniently recycled through the arrangement of the cooling bypass, meanwhile, air exchange with the external environment is reduced, only heat is transferred, impurities are not introduced, the cleanness in the main box body is guaranteed, and the safe operation performance is improved.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a cooling mechanism for a dry-type transformer and a cooling and cooling working method. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. According to the cooling method of dry-type transformers, it can be divided into natural air cooling (AN) and forced air cooling (AF). [0003] In the prior art, the air-cooled dry-type transformer starts the fan fixed on the channel steel of the foot, and the cold wind passes through the heat dissipation air passage of the transformer coil to discharge the heat during the operation of the transformer to the outside of the transformer, thereby achieving the effect of cooling. The structure is co...

Problems solved by technology

However, the exchange of outside air easily introduces impurities, resulting in a decrease in electrical insulation. At the same time, the heat generated by the transformer is not fully utilized and discharged, resulting in energy loss.
