[0002] In power systems, transformers are core equipment for energy conversion and transmission, and their operational stability is directly related to the safety and efficiency of the power grid. Transformer bushings, as a crucial component of transformers, provide electrical insulation and secure the leads. However, over long-term operation, the oil level inside the bushing may drop due to factors such as temperature fluctuations, oil aging, and seal failure. If not replenished promptly, this will affect the bushing's insulation performance and even cause failures. Currently, a variety of transformer bushing oil replenishment devices are available on the market, but most of these devices utilize manual operation or simple mechanical structures, resulting in the following drawbacks: First, the refueling process is cumbersome, requiring on-site professional operation, which is time-consuming and labor-intensive.

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a transformer bushing oil replenishing device. Figure 1-Figure 2, including a handheld frame 1, both ends of the outer wall of the handheld frame 1 are connected with handles 9 by screws, which is convenient for the staff to hold the handheld frame 1 for operation. A support plate 2 is provided on one side of the handheld frame 1, and a mounting hole 10 is opened at the center of the support plate 2. An oil replenishing pipe 3 is detachably installed inside the mounting hole 10, and one end of the oil replenishing pipe 3 is connected to an external oil pump, and the other end of the oil replenishing pipe 3 extends to the outside of the handheld frame 1 and is fixed with an oil replenisher 4. A tube hole 5 adapted to the oil replenishing pipe 3 is opened at the center of the inside of the handheld frame 1, so the oil replenishing pipe 3 is installed in the handheld frame 1 and the support plate 2 to provide stable supporting force.
[0020] In the present application, the hosting hole 5 and the mounting hole 10 are connected, and a fixing rod 6 is symmetrically fixed to the outer wall of the support plate 2 near one end of the handheld frame 1. The internal movably connected to the fixing rod 6 is a matching movable rod 7. The position of the support plate 2 close to the handheld frame 1 can be adjusted according to actual needs. At this time, the movable rod 7 will move and shrink inside the fixing rod 6, so as to facilitate the support and use of oil supply pipes 3 of different lengths. A fixing bolt 8 is provided on the fixing rod 6, and the fixing rod 6 and the movable rod 7 are fixedly connected by the fixing bolt 8 to fix the support distance, and the end of the movable rod 7 away from the fixing rod 6 is fixedly connected to the outer wall of the handheld frame 1. The setting of the support plate 2 can support one end of the oil supply pipe 3 to prevent the oil supply pipe 3 from bending and dragging.
[0021] like Figure 3 As shown, a liquid level sensor 12 is fixedly installed on one side of the bottom end of the oil replenisher 4, and a detection head 13 is connected to the output end of the liquid level sensor 12. The oil replenisher 4 is set as a hollow structure, and a through hole 14 is opened at the center of the oil replenisher 4. By installing the oil replenisher 4 on the input end of the transformer bushing, the liquid level sensor 12 extends into the inside of the transformer bushing, and the oil level inside the transformer bushing is monitored in real time through the detection head 13. In addition, a number of delivery pipes 11 are fixed at equal intervals on the inner wall of the bottom end of the oil replenisher 4. By setting up multiple delivery pipes 11, the efficiency of oil replenishment to the transformer bushing can be improved.
[0022] The implementation principle of a transformer bushing oil replenishing device in an embodiment of the present application is as follows: when in use, an external oil pump is connected in advance through the oil replenishing pipe 3, and then the user holds the handle 9 to lift the handheld frame 1 for use, so that the oil replenisher 4 is close to the outside of the transformer bushing input port. At this time, the liquid level sensor 12 extends into the inside of the transformer bushing and detects the oil level in the transformer bushing through the detection head 13. At the same time, the movable distance of the movable rod 7 in the fixed rod 6 can be adjusted according to the use length of the oil replenishing pipe 3. After adjustment, it is fixed by the fixing bolt 8. The connecting end of the oil replenishing pipe 3 can be supported by the handheld frame 1 and the support plate 2 to ensure the overall stability and prevent the connection port from loosening due to dragging. Then the oil pump is started. The oil pump works to transport the oil to the inside of the oil replenishing device 4 through the oil replenishing pipe 3, and is discharged through multiple delivery pipes 11, which greatly improves the efficiency of oil replenishment.
