Description

Technical Field

[0001] This invention belongs to the field of oil-immersed transformer protection technology, and more specifically, relates to an anti-condensation oil-immersed transformer insulation protection structure. Background Technology

[0002] Oil-immersed transformers are electrical devices in which the core and windings are completely immersed in insulating oil. The oil provides insulation, heat dissipation, and anti-aging properties. They achieve voltage transformation through the principle of electromagnetic induction and are widely used in power transmission and distribution systems. The oil medium effectively isolates moisture and oxygen, extending the life of internal components, while also providing efficient heat dissipation through natural or forced oil circulation. Compared to dry-type transformers, they have advantages such as high load-bearing capacity, low cost, and suitability for large-capacity applications, and are often used in outdoor substations, industrial and mining enterprises, and other similar locations.

[0003] The oil-immersed transformers currently in use still have the following problems: 1. They cannot assist staff in maintaining the oil-immersed transformers, affecting the maintenance efficiency; 2. After maintenance of the oil-immersed transformer is completed, the maintenance cabinet door is easily forgotten to be closed, affecting the subsequent protection effect; 3. When the air humidity is high, they cannot help remove moisture from the air, and condensation is likely to occur on the oil-immersed transformer. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, it is convenient for workers to adjust the spacing between the two connecting clamps appropriately, which is beneficial for connecting the two connecting clamps to the two utility poles. The two sets of limiting threaded nails play a positioning role for the two connecting clamps after the position is adjusted. It is also convenient for workers to maintain the oil-immersed transformer through the auxiliary ladder. The rectangular magnet plays a positioning role for the folded auxiliary ladder. Furthermore, when a worker steps onto the auxiliary ladder, the movable mounting frame and the auxiliary ladder slide downwards a certain distance under the worker's weight. As the movable mounting frame and the auxiliary ladder slide downwards under the worker's weight, the movable mounting frame can push the movable force rod forward. Under the action of the two support springs a, the movable force rod can also push the movable positioning block forward. When the worker separates from the auxiliary ladder, the movable mounting frame and the auxiliary ladder return to their original position upwards under the action of the support spring c. At this time, the support spring b pushes the movable force rod backwards, causing the rear end of the movable force rod to re-insert into the arc-shaped storage slot. When the movable force rod returns to its original position, the movable positioning block also returns to its original position.

[0016] 2. In this invention, the insulating protective cover and the movable sealing door provide shielding and protection for the oil-immersed transformer; when the controller controls the fan to work, external air enters the insulating protective cover, which provides automatic ventilation. Furthermore, when the staff pulls down the handle on the movable sealing door, the movable sealing door first pushes the movable positioning block backward, causing the two support springs a to compress. Then, under the action of the two support springs a, the movable positioning block inserts into the inclined limiting groove, which limits the movable sealing door and facilitates the staff's maintenance operations on the oil-immersed transformer. When the staff separates from the auxiliary ladder, the front end of the movable positioning block automatically separates from the inclined limiting groove, realizing the automatic reset of the movable sealing door and ensuring that the movable sealing door must be in the reset state when the maintenance of the oil-immersed transformer is completed.

[0017] 3. In this invention, the humidity sensor is used to detect the humidity of the air entering the insulating protective cover; when the humidity sensor detects that the humidity in the air exceeds the standard, the controller controls the output shaft of the servo motor to rotate intermittently by a certain angle, so that the drying impeller drives the desiccant to rotate intermittently. In addition, the two circular metal meshes require outside air to pass through the desiccant in the corresponding parts of the two circular metal meshes, which helps to remove moisture from the air and prevents condensation. When the output shaft of the servo motor drives the drying impeller to rotate intermittently at a certain angle, the used desiccant can be moved and discharged through the rectangular through hole.

Furthermore, since the two circular metal meshes 506 are fixedly installed on the left and right sides of the drying impeller 505, and the outer sides of the two circular metal meshes 506 are in contact with the inner wall of the auxiliary drying shell 501, the outside air must pass through the desiccant in the corresponding parts of the two circular metal meshes 506, which plays an auxiliary role in removing moisture in the air and has an anti-condensation effect. Also, since the bottom end of the auxiliary drying shell 501 has a rectangular through hole 5011, when the output shaft of the servo motor 502 drives the drying impeller 505 to rotate intermittently at a certain angle, the used desiccant can move and be discharged through the rectangular through hole 5011.

This ensures that the movable sealing door 404 is in the reset state when maintenance of the oil-immersed transformer 300 is completed. Then, the auxiliary ladder 204 is folded, allowing the top of the rectangular magnet 205 to contact the metal support base 101. When the humidity sensor 503 detects excessive humidity in the air... The controller 600 controls the output shaft of the servo motor 502 to rotate intermittently at a certain angle, causing the drying impeller 505 to drive the desiccant to rotate intermittently.
