Description
S11/13-m series three-phase oil-immersed distribution transformer is a new product of national science and technology, developed on the basis of the structure design of new S9 series products. The dominant idea of design is to satisfy productionProduct reliability, improve the performance of the product, according to the actual situation of the new S9 product design, readjust some loss coefficient and structure, make the loss design 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 cost lowest and the structure reasonable.
Iron core, using high magnetic conductivity, low loss of high quality high-performance silicon steel sheet 27ZH100, reduce the no-load loss and no-load current.
Winding and body, the whole series of high voltage windings are layered structure, within 500KVA and below products, low voltage windings are layered structure, (not piecewise, continuous)630KVA and above products lowThe pressure adopts new spiral type.
Body assembly summarizes the mature experience of the new S9 distribution transformer, body assembly becomes a solid whole, to ensure that the product meets the electrical performance and sudden short circuit machineMechanical strength requirements.
This series of products are fully sealed structure, to ensure the isolation of transformer oil from the outside air, prevent the aging of oil, improve the 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 strength, improved oil fluidity and heat dissipation, good welding effect and no leakage.
