[0002] During long-term operation, oil-immersed transformers inevitably experience the gradual absorption of moisture by the transformer oil due to air exchange. Therefore, it is necessary to use oil filling equipment to refill the oil in oil-immersed transformers.

[0003] In existing technologies, oil filling equipment for oil-immersed transformers with filtration functions often consists of a filtration component and an oil filling device. The oil filling device can filter the internal oil, thereby improving the cleanliness of the oil.

[0004] Existing oil-immersed transformer oil filling equipment with filtration function has limitations in handling oil containing various impurities. While the equipment can filter these impurities, it struggles to collect magnetic materials or metal debris, leading to a decrease in oil purity. Therefore, this paper proposes an oil-immersed transformer oil filling equipment with filtration function to address these issues. Summary of the Invention

[0033] Furthermore, as shown in Figure 4, a first rotating wheel 6 is rotatably connected to the bottom of the extrusion column 22; during operation, before the second transmission gear 18 extrudes the bottom end of the extrusion column 22, the first rotating wheel 6 rotates, which can effectively reduce the friction between the bottom end of the extrusion column 22 and the second transmission gear 18; the overall device improves the working life of the extrusion column 22.
