S11/13m series three phase oli mmersed distribution transformer is a new product of national science and technologydeveloped onthe basis ofthe structure design of new S9 series products. The dominant idea of design is tosatisfy production Product reliability, improve the performance of the product, according to the actual situation of the new S9 product design,readjust someloss coefficient and structure, make the loss desian value more in line with the real side value; At the same timeThe optimized design and reasonable proportion of copper and iron make the material costlowestand the structure reasonable.
This series ofproducts are fully sealed structure, to ensuretheisolation of transformer oil from the outside air, prevent the aging ofoil,improvethe reliability of transformer operation.The fuel tank uses corrugated fuel tank in the boxA long hole is opened on the wall to promote the circulation of oil in the corrugated sheet. This kind of oil tank has the
advantages of simple process,high mechanical strengthimproved oil fluidity and heat dissipation, good welding effectand no leakage.
How to deal with insulation damage of oil-immersed transformer?
1, the operation of the transformer should check and parts of the oil seepage phenomenon, transformer body no water, in order to prevent water and air into the transformer caused by transformer insulation damage.
2. The oil seal of the respirator of the transformer should maintain a certain oil level and keep smooth, and the desiccant should be kept dry to ensure good hygroscopic effect.
3. Check regularly to ensure that the explosion-proof film and safety pressure relief valve of the transformer are intact to prevent direct connection with the air, resulting in the increase of the water content of the transformer oil and the deterioration of the insulation performance of the oil.
4. When feeding the transformer, attention should be paid to the qualified oil quality in the oil storage cabinet to prevent the deterioration of the oil quality caused by the oil filling, and the bottom of the transformer is prohibited from feeding the oil tank, to prevent the impurities at the bottom of the air and the tank from entering the transformer body, especially to prevent metal impurities from entering the transformer.
