Technical Field

The invention relates to the technical field of transformers, in particular to an oil conservator structure of an oil immersed transformer.

Background

The cylindrical oil storage tank on the oil immersed transformer is the conservator, and has the effects that the oil temperature of the oil immersed transformer is increased due to the increase of the load, the oil in the oil tank expands, at the moment, too much oil flows into the conservator, and when the temperature is reduced, the oil in the conservator flows into the oil tank again, so that the effect of automatically adjusting the oil level is achieved. When the volume of the oil-immersed transformer expands or shrinks along with the change of the oil temperature, the oil conservator plays the roles of oil storage and oil supplementation, and can ensure that the oil tank is filled with oil. The side of the conservator is also provided with an oil level gauge which can monitor the change of the oil level. After the transformer is used for a long time, in order to ensure the stability of the transformer, the transformer needs to be changed with oil, the oil needs to be supplemented from an oil conservator during oil change, the old oil needs to be completely discharged during oil change of the transformer, a transformer cavity is flushed with the new oil until the oil is clean and free of impurities, the new oil can be added, the inner wall of the transformer cavity is stained with a lot of oil stains due to long-time use of the old oil, the oil stains stained on the inner wall of the transformer cavity can not be well flushed due to the traditional top-down flushing mode of the new oil from the oil conservator to the inside of the transformer, and the oil stains stained on the inner wall of the transformer cavity can not be well flushed due to the fixed direction of impact, so that the new oil added into the transformer is mixed with the oil stains of the old oil, the oil.
