Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular relates to a novel anti-seepage device for box-type transformers. Background Technology

[0002] Box-type transformers have different protection requirements during operation in different environments. Among them, water leakage of the enclosure will become an increasingly important factor in product quality during long-term use. Under the combined influence of various environmental factors, such as wind and sand, earthquakes, rainstorms, hurricanes, and ultraviolet radiation, the enclosure may crack, loosen, or break during operation, causing damage and water leakage that affects the stable operation of the equipment. Therefore, the improved mechanical anti-leakage structure is required. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a novel anti-leakage device for box-type transformers.

[0004] The technical solution adopted by this utility model is as follows: a novel box-type transformer anti-seepage device, including a base for support and fixation, a box body installed on the base, a top cover installed on the upper end of the box body, and a door panel installed on the box body;

[0005] A suspended ceiling is installed at the lower end of the top cover. The suspended ceiling is located on the upper wall of the box. A fixed drop plate is installed at the connection between the suspended ceiling and the box on the outer side of the box. A filter plate is installed on the fixed drop plate. A drip drop plate is installed on the filter plate.

[0006] The combined drop-type anti-leakage mechanical structure at the connection between the box and the ceiling prevents water from entering the box through the drop-type mechanical structure. When it rains, the water flows along the outer wall of the top cover to the position of the drip-type drop plate. Because the filter plate is higher than the position of the drip-type drop plate, the water flow stops on the drip-type drop plate and will not enter the box with the wind.

[0007] The top cover is provided with an outer top cover and an inner top cover. The outer top cover and the inner top cover are tilted at an angle greater than 3 degrees. The outer top cover and the inner top cover adopt a full welding technology with the height difference of the splicing plate to achieve mechanical waterproofing. At the same time, the double-layer full welding inside and outside provides high resistance to damage. Moreover, the large tilt angle and the greater overlap result in high risk resistance.

[0008] The inner wall of the top cover is equipped with absorbent and heat-insulating cotton, which further improves the reliability of leak prevention.

[0009] The enclosure features a U-shaped plate installed between its side wall and the base. This U-shaped plate is recessed and spliced ​​onto the base. To ensure long-term operation, the enclosure is recessed by 20mm. Internally, it is segmented welded without grinding to enhance structural strength, increase resistance to deformation, and reduce the risk of leakage. The lower end of the door panel is located on the side wall of the U-shaped plate. A waterproof strip is installed between the U-shaped plate and the base. Leaking water is discharged through the U-shaped plate, and the large-foamed strip seals the door panel for waterproofing. This double-layer structure provides protection against water leakage.

[0010] Among them, a U-shaped return channel is installed between the upper part of the door panel and the box body. The upper end of the U-shaped return channel is connected to the ceiling, and the lower end of the U-shaped return channel is located inside the door panel. When splicing the two parts, waterproof adhesive strips are attached to the overlapping parts to fix and compress the adhesive strips to prevent water leakage.

[0011] Meanwhile, the sides of the enclosure feature a stacked anti-leakage mechanical structure at the joints, with sealant applied to small gaps on the outside, and a squeezed sealing strip structure process is used to prevent leaking water from entering the enclosure.

[0012] The filter plate is provided with multiple sets of filter holes for dust prevention and ventilation.

[0013] The fixed drop plate is 23mm wide, and the drip drop plate is 17mm wide.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] 1. A combined drop-type anti-leakage mechanical structure is used at the connection between the side and top of the box body; the drop-type mechanical structure prevents water leakage from entering the box body.

[0016] 2. The top of the transformer substation adopts a drop-off full-welded + adsorption mechanical structure;

[0017] 1) Double-layer full welding inside and out, providing high resistance to damage;

[0018] 2) Larger tilt angles result in greater overlap and higher resilience to risks;

[0019] 3) Internal adsorption devices can further improve the reliability of leak prevention.

[0020] 3. The door panel and the cabinet body are connected by an external clamp and rubber strip to prevent leakage; a U-shaped backflow water guide channel and a squeeze sealing strip structure process are used to prevent water leakage into the cabinet body.

[0021] 4. The connection between the side of the box and the base is made with a recessed splicing anti-leakage mechanical structure;

[0022] 1) The structure can be welded in sections without grinding during the production and processing process, and the high resistance to deformation of the weld points reduces the risk of leakage;

[0023] 2) The mechanical structure drop process prevents water leakage into the box. Attached Figure Description

[0035] It should be noted that the combined drop-type anti-leakage mechanical structure at the connection between the box and the ceiling prevents water from entering the box through the drop-type mechanical structure. When it rains, the water flows along the outer wall of the top cover to the position of the drip-type drop plate. Since the filter plate is higher than the position of the drip-type drop plate, the water flow stops on the drip-type drop plate and will not enter the box with the wind.

To ensure long-term operation, the enclosure is recessed by 20mm. The internal structure is welded in sections without grinding to strengthen the structure, increase the resistance to deformation, and reduce the risk of leakage. The lower end of the door panel is located inside the U-shaped plate. A waterproof strip is installed between the U-shaped plate and the base to improve the water-proof performance of the enclosure.

[0039] A U-shaped reflux channel is installed between the upper part of the door panel and the box body. The upper end of the U-shaped reflux channel is connected to the ceiling, and the lower end of the U-shaped reflux channel is located inside the door panel. When splicing the two parts, waterproof adhesive strips are applied at the joints to fix and compress the adhesive strips to prevent water leakage.

[0040] The filter plate is provided with multiple sets of filter holes for dust prevention and ventilation.
