Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder coating dipping technology, specifically to a transformer insulation layer powder coating dipping device. Background Technology
[0002] The transformer insulation layer is a protective layer composed of insulating materials (such as insulating varnish, resin, etc.). It mainly covers the surface of conductive components such as coils and iron cores or fills gaps to isolate conductors at different potentials, prevent current leakage or short circuits, and improve overall performance. Insulating powder impregnation provides insulation treatment to the transformer insulation layer. The cured powder coating has high insulation strength and adhesion, effectively isolating conductive components and reducing the risk of leakage.
[0003] According to Chinese Patent CN219898819U, a transformer insulation layer powder impregnation device includes a fluidizing tank. A locking block is provided on the inner wall of the fluidizing tank. A filter cloth mounting frame is fixed above the locking block by bolts, and a filter cloth is embedded and fixed in the filter cloth mounting frame. Powder coating is placed on top of the filter cloth and spread evenly. The particle density on the filter cloth is less than the particle density of the powder, so the powder will not penetrate the filter cloth. An air pump is started, blowing air into the air blowing pipe. Because the filter cloth inside the fluidizing tank is covered with powder coating, the air blown out of the air blowing pipe is blocked. When the air below the filter cloth is full, it will blow outward through the filter cloth, and the powder coating above will be pushed upward by the air pressure, causing it to bounce upward. At this time, the heated transformer casing and its frame inside the carrying basket will be surrounded and covered by the powder blown up from the bottom, forming an impregnation effect.
[0004] In the aforementioned devices, uneven airflow distribution is prone to occur, making it difficult to ensure the uniform dispersion of insulating powder within the fluidized bed. If the airflow is strong in some areas and weak in others, the degree of powder agitation and distribution will vary at different locations, thus affecting the uniformity of the impregnation coating on the transformer casing or frame. Therefore, we provide a transformer insulation layer powder coating impregnation device. Utility Model Content

[0037] Example 2: Based on Example 1, the transformer insulation layer powder coating impregnation device provided by this utility model, such as... Figures 1 to 6 As shown: The stirring unit 52 includes a motor 521 fixedly connected to the inner surface of the mounting frame 2.

[0039] Furthermore, the stirring plate 526 is positioned below the filter plate 513 to agitate the powder coating, causing the insulating powder to form a stable fluidized state in the fluidizing tank 1, reducing local accumulation or agglomeration.
[0040] Example 3: Based on Example 1, the transformer insulation layer powder coating impregnation device provided by this utility model, such as... Figures 1 to 6As shown: The air blowing part 53 includes a connecting sleeve 531 sleeved on the outer wall of the rear end of the rotating rod 522. An annular block 532 is fixedly connected to the inner wall of the connecting sleeve 531. The inner wall of the annular block 532 is engaged with the inner surface of the annular groove 533.

The front of the air pump 536 is fixedly connected to the back of the fluidizing tank 1.
[0041] In this embodiment, the right end of the air guide tube 535 is connected to the ventilation cavity 534 opened on the rear side of the rotating rod 2 525 through the right side connecting sleeve 531, which facilitates the delivery of gas without affecting the rotation of the rotating rod 1 522 and the rotating rod 2 525.

This helps to ensure the uniformity of the transformer insulation layer coating. At the same time, the connecting sleeve 531 is rotatably connected to the annular groove 533 through the annular block 532. This ensures that the rotation of the rotating rod 1 522 and the rotating rod 2 525 is not affected when the rotating rod 1 522 and the rotating rod 2 525 are connected to the air guide pipe 535 through the connecting sleeve 531.
