S11-M series 10KV low-loss fully sealed power transformer
The S11 type three-phase oil-immersed sealed distribution transformer has the characteristics of energy saving, environmental protection, advanced technology, novel structure, beautiful appearance, etc. It can be used as an updated product of the original "S9" type transformer, suitable for 10kV or 20kV 50HZ power distribution system.
Model and meaning
Iron core: The use of high-quality cold-rolled silicon steel sheets and multiple sets of fully oblique joints step-by-step overlapping and binding structure effectively improve the distribution of magnetic flux density inside the iron core and meet the energy-saving and environmental protection requirements of low loss and low noise in the transformer.
Winding: Use high-quality oxygen-free copper material/high-strength enameled wire (or paper-covered wire) winding and multilayer cylindrical (or cake/spiral) structure, with uniform ampere-turn distribution and reasonable insulation structure. The high-voltage winding and the low-voltage winding can be wound by a conjoined body, with high efficiency and compact coils. And through optimized cooling, heat dissipation/temperature rise design. The winding turns are bundled, clamped, and the winding ends are compacted with laminated wood. In order to enhance the mechanical strength of the winding and the short-circuit withstand ability, to ensure the safe and reliable operation of the transformer.
Body: The use of hanging cores and the surrounding limit and hanging plate structure of the body effectively solves the problem of the body hanging in the air, and the body will not move, avoiding the adverse impact of the transportation bumps on the product quality; the tightness of the body is used. The firmware adopts self-locking nuts to ensure that it will not loosen after long-distance transportation. Therefore, new products do not need to be inspected before they are put into operation.
Fuel tank: Choose corrugated fuel tank or expansion radiator fuel tank structure, maintenance-free, no leakage, small size, good heat dissipation, novel structure, no oil storage tank and moisture absorber, the change of oil volume depends on corrugated fuel tank corrugated sheet or expansion type The flexibility of the radiator compensates and adjusts, expands and contracts with the increase/decrease of the temperature and the increase or decrease of the transformer insulating oil. At the same time, the transformer is isolated from the air. The aging speed of paper and other materials can prolong the service life of the product. In addition, the oil tank seal is made of oil-resistant silicone seals, which are not easy to age or crack, and do not need to be replaced after many years of use. However, the new product is simple to operate and maintain, saving users the cost of power outage maintenance.
Surface treatment and coating: After phosphate treatment, the surface of parts and fuel tanks is sprayed with three anti-paint (anti-moisture, anti-mildew, anti-salt spray), which can meet a variety of different use environments and ensure that the surface treatment coating does not fall off or Corroded, fresh color, bright, beautiful appearance.
