Abstract

A dry type transformer device with an air inlet control valve comprises a casing (80) and a plurality of winding columns (81), wherein the side wall of the casing (80) is provided with a cooling exhaust fan (83), and the winding columns (81) are arranged in the casing (80) and are evenly arranged in the circumferential direction. A cooling blowing device (82) for which air is supplied through a gas conveying pipe (61) is arranged at the bottom of the center part encircled by the winding columns (81). The cooling blowing device (82) comprises an air cavity annular casing (15) which is provided with a gas inlet pipe nozzle (6) so as to be communicated with the gas conveying pipe (61). An air inlet control valve (26) is arranged at the position of an inlet of the gas inlet pipe nozzle (6) so as to control the gas inlet amount. The air inlet control valve (26) is an electromagnetic control valve. A bottom surface annular part (152) and a drum-shaped part (151) on the upper side are integrally arranged on the air cavity annular casing (15), and the air cavity annular casing (15) is internally provided with a gas communicating cavity (150).

Description

technical field [0001] The application belongs to the field of transformers, in particular to a dry-type transformer device with an air intake control valve. 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...
