Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a transformer device capable of accelerating the circulation of transformer oil. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. When the transformer is in operation, it generates heat. Transformer oil has good insulation and heat dissipation properties. By circulating oil that flows and circulates inside the transformer, the heat generated by the iron core, windings, etc. inside the transformer is taken away, keeping the transformer temperature within a reasonable range to prevent overheating damage, and helping to maintain good insulation properties to ensure safe and stable operation of the transformer. Common oil circulation methods include natural oil circulation and forced oil circulation.

[0003] During the repeated circulation of transformer oil, impurities in the transformer oil gradually granulate, which is easy to block the pipeline and reduce the oil circulation speed. The existing patent publication number CN118888277A is a transformer that can speed up the circulation of transformer oil. A rotating ball plug is proposed until the circulating oil channel of the ball plug is aligned with the sewage outlet. The two pull rings of the filter cup are hooked with a tool to take out the filter cup and remove the granular impurities on the filter cup.

[0004] However, in practice, it is difficult to remove the filter cup during the rotation of the ball plug, and the filter cup removed in this way is stained with a large amount of oil, which is easy to pollute the environment.

[0046] Working principle: oil is injected into the oil storage cabinet 11 on the oil pillow bracket 14, and the oil is transported to the transformer body 10 through the oil pump 19 on the oil inlet pipe 12. After circulating in the transformer body 10, the oil flows back to the oil storage cabinet 11 through the oil outlet pipe 21, the filter cylinder 40, the connecting pipe 18 and the oil return pipe 13, completing the internal circulation of the entire oil between the transformer body 10 and the oil storage cabinet 11.

[0047] The oil flowing out of the oil outlet pipe 21 of the transformer body 10 during operation contains a large amount of heat. The oil outlet pipe 21 cools the oil through the cooling branch pipe 23 in the cooling cylinder 20. The cooled oil is filtered by the filter steel mesh 43 in the filter cylinder 40 and then flows back to the oil conservator 11 to improve the purity of the oil in the oil conservator 11.

The rotating gear will drive the L-shaped cleaning brush 41 to brush and clean the bottom side of the filter steel mesh 43, and brush and clean the impurities blocked at the bottom of the filter steel mesh 43, thereby completing the removal of impurities on the filter steel mesh 43.

The circular slider 62 realizes stable and smooth reciprocating motion on the limiting base 61 through the limiting slide groove 64 and the limiting slider 65. The limiting slider 65 will drive the piston plate 57 on the piston rod 51 to reciprocate back and forth in the cleaning cylinder 50. When the piston plate 57 is pumped in the cleaning cylinder 50 to generate negative pressure, the oil will be pumped from the oil storage cylinder 52 into the cleaning cylinder 50 through the second conduit 54 and the one-way valve. When the piston plate 57 is squeezed in the cleaning cylinder 50 to generate positive pressure, the oil will be pumped into the cleaning cylinder 50 through the third conduit 54. 9 and the one-way valve transport the oil in the cleaning cylinder 50 to the spray head 58 on the cleaning ring 56, and the oil is sprayed onto the filter steel mesh 43 through the spray head 58 to take away the impurities removed by the L-shaped cleaning brush 41, and the impurities are taken away by the oil through the drain pipe 30 to complete the removal and cleaning of the impurities on the filter steel mesh 43. The worker opens the rotary sealing plug on the drain pipe 30 to take away the oil containing impurities, and then uses the filtering equipment to filter the oil containing impurities. The filtered oil is injected into the oil storage cabinet 11 to complete full utilization. After the impurities are removed, the rotary motor 74 is closed to open the valves on the oil pump 19 and the oil outlet pipe 21.

[0050] During the annual maintenance process, the connecting pipe 18 is removed from the oil return pipe 13 and the filter cartridge 40 through the flange, and then the sealing cover 46 is rotated to open the filter cartridge 40, and then a tool is used to penetrate the connecting ring 48 on the filter steel mesh 43, so that the filter steel mesh 43 is rotated in the L-shaped limit groove 42 and then taken out to replace or finely clean the filter steel mesh 43. After completion, the sealing cover 46 is used to seal the filter cartridge 40, and then the connecting pipe 18 is assembled through the flanges at both ends.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
