Transformer oil replacing device

Abstract

The invention relates to a transformer oil replacing device. The device comprises a U-shaped pipe; a first communicating opening, a second communicating opening and a third communicating opening are formed in the U-shaped pipe; the first communicating opening is communicated with a transformer body; the second communicating opening is communicated with a communicating pipe; the communicating pipe can be communicated with the transformer body to form a communicating device; a sensing structure is arranged on the communicating pipe; the third communicating opening is communicated with a first collecting box and a second collecting box; a pushing structure capable of pushing transformer oil to wash impurities on the inner wall of the transformer body is arranged on the first collecting box; the sensing structure can sense the liquid level in the communicating pipe and can start the pushing structure to work; and a drawing structure capable of drawing out transformer oil in the transformer body is arranged on the second collecting box. According to the transformer oil replacing device of the invention, by utilizing the sensing structure, the pushing structure and the drawing structure which are linked, the transformer oil and impurities in the transformer body are timely and rapidly discharged, so that rapid pollution of the transformer oil after oil change caused by the impurities attached to the inner wall of the transformer body is avoided, and the oil change and impurity removal effects are improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a transformer oil replacement device. Background technique [0002] In the power industry, power oil is the general term for various insulating oils. Many equipment need to use insulating oil, such as transformer oil in the transformer oil tank, and the transformer oil plays the role of insulation and cooling. [0003] After the transformer oil is used for a long time, there will be carbon deposits, which will make the transformer oil contain impurities. The transformer oil needs to be cleaned and replaced regularly. Impurities will not flow out together with the release of transformer oil. After the replaced transformer oil rushes into the interior of the transformer, the impurities attached to the inner wall of the transformer will quickly cause pollution of the newly replaced transformer oil, reducing The effect of transformer oil replacement treatment. [0004] Ther...

Problems solved by technology

[0003] After the transformer oil is used for a long time, carbon deposits will appear, which will make the transformer oil contain impurities. The transformer oil needs to be cleaned and replaced regularly. The existing transformer replacement process When the transformer oil is released directly, the impurities attached to the inner cavity wall of the transformer will not flow out together with the release of the transformer oil. The impurities will quickly cause the pollution of the newly replaced transformer oil, reducing the effect of transformer oil replacement treatment
