Description

Technical Field

[0002] At present, a large number of transformers are needed in power plants, power supply stations, substations, and large industrial and mining enterprises. Moreover, most of the transformers currently used, whether large main transformers or small transformers, are still oil-immersed. Oil-immersed transformers are filled with special transformer oil inside the transformer, and the transformer oil plays the role of insulation, cooling, and corrosion prevention in the oil tank. It can be seen that the quality of transformer oil plays a vital role in a transformer, so the daily detection of transformer oil quality indicators is very important. The acid value indicator can directly reflect the aging degree of transformer oil.

[0003] Since insulating oil plays an insulating role in the equipment, its acid value must be controlled within a certain range. If the acid value is too high, the corrosiveness of the insulating oil will increase, thereby accelerating the aging of the equipment and reducing the service life of the equipment. At the same time, the acid value of the insulating oil can also reflect the aging degree of the oil and the possible content of acidic substances; in the prior art, the equipment for testing oleic acid needs to manually pour the insulating oil to be tested into the sample cup, and pour the extractant and neutralizer into the sample cup to extract and neutralize the insulating oil.
