High-efficiency oil-immersed transformer capable of quickly exhausting gas

Abstract

The invention discloses a high-efficiency oil-immersed transformer capable of quickly exhausting gas. The high-efficiency oil-immersed transformer structurally comprises a high-voltage wiring terminal, a heat dissipation plate, a fixed base, an oil discharge pipe, an oil tank main body, an oil filling pipe and a low-voltage wiring terminal. According to the oil-immersed transformer, an oil pipe control valve, a rectifying fin, an exhaust structure and an oil guide device are adopted in a matched mode, and when the transformer needs maintenance and refueling, the working personnel directly injects new transformer oil into the oil tank main body from the oil filling pipe, the residual bubbles in the transformer oil can be directly discharged out through the exhaust structure, and the purityof the new transformer oil is improved; and after oiling is completed, the transformer can be started to start to work, so that the time for waiting for self-discharging of the bubbles is shortened, the power failure time caused by overhauling of the transformer is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric 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, 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 ...

[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
