Product description
S11-M series 10KV distribution transformer is the most commonly used distribution transformer in China.
Main Functions & Features (S11-M Series 10KV Distribution Transformer)
1、 Core: The core is made of cold-rolled oriented silicon steel sheet with a thickness of 0.30mm or 0.27mm, and the stepped coiled core is made of a jointless structure, which is rolled on the core winding machine, first winding 2 small frame cores, and then rolling a large frame outside the 2 small frame cores to form a three-phase coiling core, after the completion of rolling, it is then loaded into the core annealing furnace, and the core performance can be fully restored by vacuum and nitrogen annealing, therefore, the no-load loss of this series of transformers is very low, and the no-load loss is reduced by 30 on average compared with the S9 series 10KV distribution transformer% is a better low-loss distribution transformer.

2. Coil: The coil winding of the coiled core transformer needs to use a special winding machine, which is directly wound on the core, and the high and low voltage coils are wound at the same time, and there is no need to use the winding die.
3. Assembly: When assembling, it is no longer necessary to disassemble the iron yoke on the core, which can prevent the increase of the core loss in the assembly process.
4. Fuel tank: The oil tank of the coil core distribution transformer is all sealed with corrugated sheets.
S11-M-160/10-0.4 Three-phase oil-immersed transformer conditions:
1. Device type: outdoor type.
2. Normal environmental use conditions: the altitude is not more than 1000m, and the ambient temperature is 40 °C, -25 °C.
3. Installation environment: no corrosive gas, no obvious dirt environment.
Iron core: all of them are made of high-quality grain-oriented cold-rolled silicon steel sheets, full oblique non-porous binding structure, the iron core is multi-step stepped, three seams or five seams, low air loss and low noise: the coiled iron core is directly wound with first-class equipment, no joints, no angular weight, reducing magnetic resistance and low air loss; The core of the amorphous alloy transformer is made of materials produced by Unicredit in the United States, which reduces the air loss by 72% on average compared with the traditional silicon steel sheet , no-load current 50%.
Coil: It is made of high-quality QQ enameled round copper wire, flat copper coin or copper knot drawn by oxygen-free copper rod, and its forms include cylindrical type, continuous type, new spiral type, split type, etc., which have sufficient electrical strength, mechanical strength and heat dissipation capacity.
Fuel tank: made of high-quality steel plate welding, elliptical type, rectangular type and other structures, heat dissipation elements using sheet radiator, expansion radiator or corrugated fuel tank, the fuel tank in the factory for reliable sealing test, the inner and outer surfaces after pickling, phosphating treatment, three bottom one side paint coating, both anti-corrosion and beautiful and generous.
S11-M new energy-saving oil-immersed transformer, 10KV energy-saving transformer using imported silicon steel sheet to ensure the performance and quality of the core, high-quality copper magnet wire, electrical-grade insulating wood, capacity in the range of 630~2000kvA low-voltage winding using barrel or spiral structure, ampere turn distribution balance, strong short-circuit resistance, no deformation, no bursting, high mechanical strength. 2. The 10KV energy-saving transformer adopts corrugated oil tank, cancels the oil conservator, selects high-quality components, and installs pressure release valves, signal thermometers, gas relays, etc. according to standard requirements to ensure the safe operation of the transformer. Product attributes: The oil tank and clamps are treated with rust removal, pickling, phosphating and multiple baking paints, and the imported special anti-rust paint is used, which does not fall off or fade, and can meet the special use requirements of metallurgy, petrochemical systems and humid and polluted areas. 4. The transformer adopts a fully sealed structure, the box cover is folded and designed, completely welded or sealed and fastened with stainless steel bolts, the seals are made of aerospace rubber and plastic products, the transformer oil is isolated from the air, waterproof and moisture-proof, which delays the aging of the oil quality and prolongs the service life of the transformer. Installation and operation of Taixin S11-M new energy-saving oil-immersed transformer installation site: no corrosive gas, no obvious dirt environment Main features of oil-immersed transformer performance characteristics a. In addition to the small capacity of copper wires, the low-voltage windings of oil-immersed transformers generally adopt a cylindrical structure of copper foil winding; The high-voltage winding adopts a multi-layer cylindrical structure, so that the ampere-turn distribution of the winding is balanced, the magnetic flux leakage is small, the mechanical strength is high, and the short-circuit resistance is strong. B. The core and winding have adopted fastening measures, and the fastening parts such as the height and low-voltage lead are equipped with self-locking locknuts, and the non-hanging structure is adopted, which can withstand the shock of transportation. c. The coil and core are dried by vacuum, and the transformer oil adopts the process of vacuum oil filtration and oil injection, so that the moisture inside the transformer is minimized. d. The oil tank adopts corrugated sheets, which has a breathing function to compensate for the volume change of oil caused by temperature changes, so the product does not have an oil conservator, which obviously reduces the height of the transformer. e. Because the corrugated sheet replaces the oil conservator, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and water from leading to the decline of insulation performance. f. According to the above five performances, it ensures that the oil-immersed transformer does not need to change oil during normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
