Description

Technical Field

[0001] The utility model belongs to the technical field of dry rectifier transformers, and particularly relates to an air-cooling structure of a dry rectifier transformer. Background Art

[0002] A rectifier transformer is a power transformer of a rectification device. The characteristic of a rectification device is that the primary side inputs alternating current, and the secondary side outputs direct current after passing through rectifying elements. Commutation is the general term for three working modes: rectification, inversion, and frequency conversion, and rectification is the most widely used one among them. A transformer used as the power supply of a rectification device is called a rectifier transformer.

[0003] Since rectifier transformers are relatively fragile, in order to reduce the damage of the external environment to rectifier transformers, rectifier transformers are usually placed in a housing. When the rectifier transformer is in use, a large amount of heat will be generated. Then, an air-cooling structure needs to be installed in the housing for heat dissipation. Most of the existing air-cooling structures are installed in dry rectifier transformers. Once the air-cooling structure in the housing is damaged, it is inconvenient to maintain and replace the air-cooling structure. At the same time, if only air-cooling is used for heat dissipation, the heat dissipation efficiency of the transformer will be low, which greatly affects its subsequent processing. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings of the prior art, the utility model provides an air-cooling structure of a dry rectifier transformer, which can effectively solve the problems of the prior art.

[0010] Furthermore, ventilation holes are uniformly opened on the upper end surface of the cover plate body.

[0011] Further, the limiting mechanism includes a limiting groove and a limiting sliding rod. The limiting groove is opened on one side of the cover plate body. The limiting sliding rods are symmetrically fixed on the left and right sides of the inner wall of the limiting groove, and the cross-section of the limiting sliding rod is a "T" - shaped structure. The limiting sliding rods are slidably clamped on the left and right sides of the fan rack plate.

[0012] Further, an activated carbon filter plate is arranged on the lower end surface of the cooling plate.
