Abstract

The invention relates to a control system of a dry-type transformer device. The control system comprises a digital signal processor (DSP) controller, a motor driving circuit and the dry-type transformer device, wherein the dry-type transformer device comprises a shell (80) and a plurality of winding posts (81), wherein a cooling exhaust fan (83) is arranged on the lateral wall of the shell (80), the plurality of winding posts (81) are arranged in the shell (80) and uniformly distributed on a peripheral direction, a cooling blower (82) is arranged at the bottom of a central part encircled by the plurality of the winding posts (81), air is supplied to the cooling blower (82) through a gas delivery pipe (61), the cooling blower (82) comprises an air cavity annular shell (15), the air cavity annular shell (15) is provided with a gas inlet pipe mouth (6) communicated with the gas delivery pipe (61), and provided with an annular part (152) at the bottom surface and a cylindrical part (151) at the upper side in an integrated manner, and a gas communication cavity (150) is arranged in the air cavity annular shell (15).

Description

technical field [0001] The application belongs to the field of transformers, in particular to a dry-type transformer device control system. 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 p...
