A high-efficiency oil-immersed transformer with fast exhaust

Abstract

The invention discloses a high-efficiency oil-immersed transformer capable of rapid exhaust. The rectifying fins, exhaust structure, and oil guiding device are coordinated. When the transformer needs to be repaired and refueled, the staff will directly pour new transformer oil into the main body of the oil tank from the oil filling pipe, and the residual air bubbles in the transformer oil can be directly passed through the exhaust structure. Discharge improves the purity of the newly added transformer oil. After refueling, the transformer can be started to work, reducing the time for waiting for the air bubbles to be discharged by themselves, shortening the power outage time caused by transformer maintenance, and improving work efficiency.

Description

Technical field[0001]The invention relates to the field of power equipment, in particular to a high-efficiency oil-immersed transformer capable of rapid exhaust.Background technique[0002]The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. With the continuous development of the National Grid, the transformer has become an indispensable equipment in circuit transmission. Among them, oil-immersed transformers have become the choice of users due to their strong performance and easy maintenance. One, but the current technical considerations are not perfect, and it has the following shortcomings: oil-immersed transformers will produce impurities in the tank and precipitate at the bottom after a long time of use. The oil needs to be drained to drain the impurities before refueling to ensure the normal operation of the transformer, but During the oil change process, the transformer oil easily mixes with air and flows into the oil tank. ...

[0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. With the continuous development of the national grid, the transformer has become an indispensable equipment in circuit transmission. Among them, the oil-immersed transformer has become the choice of the majority of users due to its strong performance and easy maintenance. One, but the current technical considerations are not perfect, and it has the following disadvantages: After the oil-immersed transformer has been used for a long time, impurities will be generated in the oil tank and precipitated at the bottom, and it is necessary to drain the oil and then refuel to ensure the normal operation of the transformer. During the oil change process, the transformer oil is easy to mix with air and flow into the oil tank. The purity of the transformer oil in the transformer will be reduced, and the insulation of the transformer oil containing air will also be reduced, which will easily cause the transformer to be damaged. Therefore, the transformer oil in the transformer oil tank After the oil change, it needs to stand still for a few hours and wait for the air bubbles to be automatically discharged before starting the transformer to start working, which has low working efficiency
