The product adopts advanced technology from Germany, integrates the advantages of flameproof transformers at home and abroad, adopts a full corrugated cylinder flameproof shell, a special-shaped bellows formed at one time, and the shell is equipped with a guide heat dissipation plate, which has a unique and efficient heat dissipation effect.
The body insulation system is H-class DuPont NOMEX insulation material, non-encapsulated oblong coil, flat copper wire vertical winding structure, using international advanced level of special technology: VPI vacuum pressure impregnation, multiple impregnation by the United States UL certification solvent-free insulating paint, and then after baking and curing, the product has the characteristics of high electrical strength and good impact performance.
The iron core is made of foreign high magnetic permeability material, oblong cross-section, no punching 200 compression belt binding type, compact structure, strong and reliable.
The appearance of the product is round, small size, beautiful appearance, light weight, reliable flameproof performance, electrical performance indicators (compared with GB8286-1996 national standard: no-load loss is reduced by 14% on average, load loss is reduced by 10% on average) leading similar products in China, reaching the advanced level of similar products in the world, filling the domestic gap.
The 3150KVA oil-immersed transformer is a transformer with a flameproof housing
This series of new products is a non-encapsulated dry-type transformer made of high-quality NOMEX insulating material. Its high and low voltage windings are long and round, and the high-voltage coil adopts a special process of vertical winding of flat copper wires. It is impregnated with H-grade solvent-free paint by VPI vacuum pressure and cured at high temperature. So as to improve the mechanical strength of the coil and achieve the effect of reducing the size of the whole machine. The core is made of high-quality high-permeability cold-rolled oriented (0.27-0.30) thin silicon steel sheet, the core column and iron yoke are oblong cross-section, no punching full oblique 45° joint, the core column and iron yoke are fastened with stainless steel pull plate and H200 tightening belt, compact structure, reliable and advanced, and effectively reduce the no-load current and no-load loss.
The flameproof shell adopts a special conductor bellows (domestic blank) structure, the upper and lower parts of the shell are arc type, the two sides are vertical corrugations, and the inside and outside are equipped with guiding heat dissipation reinforcing plates, which have good heat dissipation performance, improve the heat dissipation effect and mechanical strength of the whole machine, and enhance the reliability of the product.
Use environment: There is methane mixed gas and coal dust in the mine, and there is a high risk in the mine, mine, tunnel and other places; and in the absence of gases and vapours sufficient to corrode metals and destroy insulation; There is no strong turbulence vibration and the vertical plane inclination does not exceed 35°.
Normal environmental use conditions: the altitude does not exceed 1000m. The ambient temperature is up to +40°C, the lowest is -25°C, and the average annual temperature is +20°C
Special environmental use conditions: more than 1000m above sea level. The ambient temperature is up to +40°C and the lowest is -45°C. (If it does not meet the above conditions, it will be explained in detail when ordering, and appropriate adjustments can be made according to the relevant provisions of the corresponding standards)
