Product Description

The S1 1-M series three-phase oil-immersed distribution transformer is a new product of national science and technology. The design idea developed on the basis of the structural design of the new S9 series product is to meet the reliability of the product and improve the performance of the product. The actual situation of the new S9 product has readjusted some loss coefficients and structures to make the loss design value more in line with the real side value: at the same time, optimized design and reasonable determination of the copper-iron ratio have been made to lower the material cost and the structure.

The iron core adopts high-quality high-performance silicon steel sheet 27zHloo with high magnetic permeability and low loss, which reduces no-load loss and no-load current.

Winding and body, the whole series of high-voltage windings adopt a layered structure. In 500KVA and below products, the low-voltage winding is a layered structure, (not segmented, continuous) 630KVA and above products use a new type of spiral for low voltage: body assembly summary With the mature experience of the new S9 distribution transformer, the body becomes a solid whole after assembly to ensure that the product meets the electrical performance and mechanical strength requirements during sudden short circuit.

This series of products is fully sealed structure. It ensures the isolation of transformer oil from outside air, prevents the aging of oil, and improves the reliability of transformer operation. The oil tank uses a corrugated oil tank with a long hole in the upper and lower sides of the tank wall. In order to promote the circulation of oil in the corrugated sheet. The oil tank has a simple process, high mechanical strength, improved fluidity and heat dissipation capacity of the oil, good welding effect, and is not easy to leak.
