Background

Transformers are devices for changing ac voltage using the principle of electromagnetic induction, and can be classified into dry type transformers, oil-immersed transformers, fluoride transformers, and the like according to the cooling method. The oil for the oil-immersed transformer realizes the functions of cooling, insulation and the like. The oil level is too low, which causes the lead wire or iron core of the transformer to be exposed to the air, causing the danger of internal flashover, and the insulation of the transformer oil will be rapidly reduced due to the increased contact area between the oil and the air, so that the transformer needs to be supplemented with the insulation oil periodically by using an oil storage tank for the transformer. The stored oil for the transformer is classified according to the type of the insulating oil, and generally comprises new transformer insulating oil, used transformer insulating oil and regenerated transformer insulating oil, wherein different types of insulating oil are stored in different oil storage tanks, and different oil storage tanks are selected according to the requirement of the transformer to perform oil supplementing operation on the transformer.
