Baoding oil immersed transformer is inseparable from transformer oil, it is in the transformer oil constantly soaked, so the quality of transformer oil is a direct impact on the quality of baoding oil immersed transformer is an important guarantee. The type of transformer that present and category are undertaking increasing ceaselessly, all sorts of technology and performance are uneven also, because this is choosing transformer, should notice to look forward to quality. Of transformer oil all sorts of occurrence problem appear the aging that appears most is transformer oil, this often can appear, so transformer oil is to want to accomplish ageing differentiate, what is common differentiate method?

Oil-immersed transformer

(1) prevent transformer overload, in order to avoid the oil temperature jumped to more than 85 ℃. If the oil temperature is too high, part of the hydrocarbon in the oil will decompose and form sludge, and the acid value of the oil will surge and age.

(2) if the capacity is 750 kva or above, the equipment itself is equipped with a hygroscopic device. The hygroscopic chamber is usually filled with silica gel or calcium chloride, which should be treated or replaced frequently in case of damp. Discolored silica gel is affected by moisture when the signs are blue to pink, silica gel can be heated to restore the original color; Calcium chloride is affected by moisture when the signs of condensation into blocks, should be replaced.

(3) a silica gel bag can be placed in the small transformer to immerse in the oil. Silica gel can regenerate the oil and prevent aging. The content of silica gel is about 5% of oil weight.

(4) in the maintenance of transformers, care should be taken not to make oil and no covering copper parts (bare copper surface is suitable for tin plating or tin lining) or iron parts (iron parts surface is suitable for painting) contact, such as oil and copper, iron, zinc contact surface is the larger, the more likely to aging.

Above is the transformer oil aging inspection method, to do a reasonable test, to ensure that the transformer oil is qualified, but also to continue to improve the quality of inspection and standards, this is the basic requirements of oil-immersed transformer oil, otherwise baoding oil-immersed transformer will not be safe operation!
