Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an air-cooled dry-type transformer. Background Art

[0002] The main cooling method for air-cooled dry-type transformers is air. Forced air cooling can make the transformer have a good cost-effectiveness, but for this cooling method, the structure of the transformer's air duct directly affects its effect.

[0003] For example, a Chinese patent with the announcement number CN211125280U discloses an air-cooled dry-type transformer, including a base, three dry-type transformers are fixed to the middle of the top of the base by bolts, vertically arranged rotating rods are movably connected to both sides of the top of the base, a stepping motor is fixed to the inside of one side of the base by bolts, and a control device is also arranged on one side of the inside, a connecting block is sleeved on the outside of the rotating rod, a mounting plate is sleeved and fixed on the outside of the connecting block, and six heat dissipation fans are installed on the surface of the mounting plate;

[0004] The technical solution recorded in this scheme uses a stepper motor to drive the two rotating rods on both sides of the base to rotate synchronously using a driving gear, a transmission gear and a synchronous belt, thereby driving the connecting block whose inner wall is provided with a thread groove corresponding to the thread on the surface of the rotating rod to achieve lifting and lowering, so that the mounting plate installed on the outside of the connecting block drives the heat dissipation fan fixed inside to continuously dissipate heat from the upper and lower parts of the dry-type transformer. However, when this scheme is in use, the six heat dissipation fans are fixed on the surface of the mounting plate, resulting in a large space being occupied, and the six heat dissipation fans generate large vibrations when running at the same time, affecting the operation of the transformer.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an air-cooled dry-type transformer is provided to achieve a purpose with greater practical value. Utility Model Content
