[0031] Embodiment 1:
[0032] Reference Figure 1 To Attachment Figure 7 As shown, an insulating cylinder oil dipping device according to a preferred embodiment of the utility model is schematically shown. The insulating cylinder oil dipping device 1 can perform oil dipping and draining treatment on an insulating product, is easy to operate, and reduces the consumption of time and labor costs.
[0033] Figure 1 and Figure 2 1 is a schematic diagram of the overall structure of the insulating cylinder oil immersion device 1 according to the first preferred embodiment of the utility model. In this embodiment, the insulating cylinder oil immersion device 1 includes an oil immersion device 10, a draining device 20 and a stepping platform 30, the oil immersion device 10 is installed on the stepping platform 30, the draining device 20 is connected to the stepping platform 30, the oil immersion device 10 is used to immerse the insulating product in oil, and the draining device 20 is used to drain the insulating product.
[0034] in Figure 3 It is a front view of the insulating cylinder oil immersion device 1 according to the utility model. Figure 4 It is a side view of the insulating cylinder oil immersion device 1 according to the utility model. Figure 5 It is a top view of the insulating cylinder oil immersion device 1 according to the utility model. The oil immersion device 10 includes an oil immersion body 11, a rolling machine 13 and an oil immersion tank 12. The oil immersion body 11 is arranged on the step platform 30, and the oil immersion tank 12 is arranged in the oil immersion body 11. In other words, the oil immersion tank 12 extends downward from the surface of the oil immersion body 11, and the rolling machine 13 is installed in the oil immersion tank 12. The rolling machine 13 is arranged in the oil immersion tank 12 of the insulating cylinder oil immersion device 1, so as to roll and immerse the oil evenly on the surface of the insulating product, and the degree of automation is high.
[0035] The oil immersion tank 12 is used to place oil, preferably #25 or #45 transformer oil. The oil immersion time of the insulating product is maintained at 5 to 8 hours and cannot be less than 30 minutes to ensure that the insulating product is fully immersed in oil. The rolling machine 13 is used to drive the insulating product, and then the oil is evenly rolled and immersed on the surface of the insulating product, with a high degree of automation. The rolling machine 13 is driven by a motor and a reducer to drive the sprocket to roll.
[0036] The oil immersion device 10 also includes a limiting portion 14, and the limiting portion 14 is arranged on one side of the oil immersion body 11, so that when the rolling machine 13 drives the insulating product, it prevents the insulating product from rolling away from the oil immersion tank 12, causing damage to the insulating product. In this embodiment, the limiting portion 14 is arranged on one side of the oil immersion body 11. In other embodiments, the limiting portion 14 can be arranged on the left and right sides of the oil immersion body 11, and the shape of the limiting portion 14 is suitable for change. In this embodiment, the limiting portion 14 is set to be an arc shape to conform to the circumferential shape of the insulating product. In this regard, those skilled in the art should understand that the number and shape of the limiting portion 14 are not limitations of the present utility model.
[0037] The drain device 20 includes a drain body 21 and a drain groove 22, wherein the drain groove 22 is disposed in the drain body 21. In other words, the drain groove 22 extends downward from the surface of the drain body 21. The drain groove 22 is used to store oil dripping from the surface of the insulation product.
[0038] It is worth mentioning that, in this embodiment, the drain tank 22 of the drain device 20 is interconnected with the oil immersion tank 12 of the oil immersion device 10, so that the oil in the drain tank 22 can flow into the oil immersion tank 12 by itself for recycling. In other words, after the insulating product is immersed in oil in the oil immersion tank 12, the surface is immersed in oil, and then placed in the drain device 20 for draining. During the draining process, the excess oil on the surface of the insulating product will drip into the drain tank 22, and finally the oil will flow back from the drain tank 22 to the oil immersion tank 12 for reuse in the oil immersion process of the insulating product, avoiding manual oil change and oiling.
[0039] The draining device 20 further includes a grid member 23, which is installed in the draining tank 22. The grid member 23 is used to place the insulating product, that is, after the insulating product is immersed in oil in the oil immersion tank 12, it is suitable to be placed in the grid member 23 for draining. The grid member 34 can increase the draining speed of the insulating product and ensure the draining efficiency of the insulating product.
[0040] In addition, the insulating product needs to be dried before the oil immersion treatment. Preferably, an electric oven is used for the drying treatment. After drying, the insulating paperboard product needs to be placed in the oil immersion device 10 for oil immersion treatment within 3 hours. During the draining process of the insulating product after the oil immersion treatment, care should be taken to prevent dust from adhering. Because during the draining process, once dust is attached, it is difficult to remove. When the transformer oil on the surface of the insulating product no longer flows down, it should be wrapped with a plastic film as soon as possible to prevent the insulating product from absorbing moisture again.
[0041] In this embodiment, it should be noted that the insulating product will still absorb moisture after the oil immersion treatment. However, the moisture absorption rate is greatly slowed down, so the insulating product after the oil immersion treatment cannot be exposed to the atmosphere for a long time. Finally, if the insulating product after the oil immersion treatment has not entered the transformer body drying process within 60 days, it must be dried, oil immersed and drained again.
[0042] Figure 6 and Figure 7 It is a schematic diagram of the dimensions of the insulating cylinder oil immersion device 1 according to the utility model. The dimensions of the insulating cylinder oil immersion device 1 are set according to the actual oil immersion treatment and draining treatment to ensure that the oil immersion treatment and draining treatment of the insulating product are carried out smoothly.

In this embodiment, the oil immersion device 10 is located at the center of the step platform 30. Based on this, the distance L10 from the left edge of the oil immersion body 11 of the oil immersion device 10 to the left edge of the step platform 30 is 400. Similarly, the distance L10 from the right edge of the oil immersion body 11 of the oil immersion device 10 to the right edge of the step platform 30 is also 400. Based on this, the edge thickness of the oil immersion body 11 of the oil immersion device 10 is 20. The size of the insulating cylinder oil immersion device 1 is set according to the actual oil immersion treatment and draining treatment to ensure that the oil immersion treatment and draining treatment of the insulating product are carried out smoothly. In this regard, those skilled in the art should understand that the size of the insulating cylinder oil immersion device 1 is not a limitation of the present invention.
