Abstract

The invention relates to a heat-dissipation dry type transformer device. The heat-dissipation dry type transformer device includes a shell (80) of which the side wall is provided with a cooling exhaust fan (83) and a plurality of winding columns (81) which are arranged in the shell (80) and are uniformly distributed along a circumferential direction; the bottom of a central portion surrounded by the plurality of winding columns (81) is provided with a cooling blowing device (82); a gas conveying pipe (61) supplies gas for the cooling blowing device (82); the cooling blowing device (82) includes a gas inlet pipe mouthpiece (6) and a gas cavity annular shell (15) communicated with the gas conveying pipe (61); and the gas cavity annular shell (15) is integrally provided with a bottom surface annular portion (152) and a cylindrical portion (151) at the upper side of the bottom surface annular portion (152); and a gas communication cavity (150) is arranged in the gas cavity annular shell (15).

Description

technical field [0001] The application belongs to the field of transformers, in particular to a heat-dissipating dry-type transformer device. Background technique [0002] Dry-type transformers often have multiple winding column assemblies to meet power needs. In some places where the installation environment is limited, these multiple winding columns can be arranged in a circular manner. However, the cooling ventilation in this arrangement requires a special design to meet the needs of cooling and ensure the safe operation of the equipment. [0003] The existing ventilation device quickly cools down the temperature of transformer components such as windings in the casing by setting a fan. However, there may be local overheating in the individual winding columns of the transformer, which has a particularly large impact on safe operation and poses a potential risk to the safety of the equipment. Contents of the invention [0004] The object of the present invention is to...
