Abstract

The invention discloses a dry type transformer device using position sensors. The device comprises a shell (80) and multiple winding pillars (81), wherein a cooling exhaust fan (83) is arranged on the side wall of the shell (80), the multiple winding pillars (81) are evenly arrayed inside the shell (80) in the peripheral direction, a cooling blast device (82) is arranged at the bottom of the center surrounded by the multiple winding pillars (81), air is supplied to the cooling blast device (82) through an air conveying pipe (61), the cooling blast device (82) comprises an air inlet mouthpiece (6) and an air cavity ringlike shell (15) which is communicated with the air conveying pipe (61), the air cavity ringlike shell (15) is integrally provided with a bottom face ringlike part (152) and a tube-shaped part (151) which is located at the upper side, and an air communication cavity (150) is formed inside the tube-shaped part (151).

Description

technical field [0001] The application belongs to the field of transformers, in particular to a dry-type transformer device using a position sensor. 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 inventio...
