The description of SG (B) 10 type H insulated dry-type power transformer

SG (B) 10 type H insulated dry-type power transformer has strong thermal shock resistance, large overload capacity, flame resistance, high fire resistance, low loss, small partial discharge, low noise, no harmful gas, and no pollution , Insensitive to humidity, dust, small size, non-cracking, easy to maintain. Therefore, it is suitable for use in harsh environments with high fire resistance requirements, large load fluctuations and dirty and humid environments such as: airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping malls, densely populated areas and special environments such as petrochemicals, nuclear power plants, and nuclear submarines.

The structure of SG (B) 10 type H insulated dry-type power transformer

The core of SG (B) 10 type H insulated dry-type power transformer is made of imported grain-oriented high-quality and high-permeability silicon steel sheets laminated with a 45 ° full oblique seam structure. The elastic fixing device is used between the winding and the core, so that the compressor has low no-load loss and noise. The processing technology not only reduces the noise of the transformer, but also prevents the iron core from rusting during the operation of theSG (B) 10 type H insulated dry-type power transformer.

The iron core is moderately clamped by a pull screw, the upper and lower clamps are connected by a pull plate and fixed to the base as a whole, and the winding is fixed by an elastic pad. The buffer structure can reduce the degree of vibration and noise.

High and low voltage coils of SG (B) 10 type H insulated dry-type power transformer

The high and low voltage coils are made of Nomex insulation material and they have been subjected to multiple solvent-free paint varnishes by VPI vacuum pressurization equipment. The high-voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation conditions, which avoids the shortcomings of high-layer voltage, poor heat dissipation, easy thermal breakdown and low mechanical strength of the multilayer cylindrical coil. Thereby improving product operation. The low-voltage coil of SG (B) 10 type H insulated dry-type power transformer adopts a foil-type high-current spiral structure with a longitudinal airway. The coils with diffused stains have excellent moisture resistance that can withstand impact, no cracks, no partial discharges and easy to dry out and recover after life for protecting the environment.

The advantages of SG (B) 10 type H insulated dry-type power transformer

SG (B) 10 type H insulated dry-type power transformer adopts new structure, new materials and new technology. It has good heat dissipation conditions, long thermal life and strong overload capacity. It can work safely and reliably for a long time under 20% overload. In the old 23 environment, no fan cooling is required, and it can still run at full load for a long time.

SG (B) 10 type H insulated dry-type power transformer has good safety performance today. All insulation materials are non-combustible, self-extinguishing, non-toxic, and the flammable substances are less than 10% of the epoxy castable products. They can be burned at a high temperature of 80 ° C for a long time without the generation of toxic fumes, thereby overcoming the epoxy castable transformers combustion. The SG (B) 10 type H insulated dry-type power transformer with toxic gas defects is even more superior in places with high safety requirements, damp heat, and poor ventilation. such as power, subways, ships, chemicals and metallurgy.

reliability

The special coil design, technology and materials of the SG (B) 10 type H insulated dry-type power transformer make the product's three-proof performance extremely negligible (moisture-proof, mildew-proof, and salt-fog-proof) and can withstand thermal shock without cracks and partial discharge. The insulation system based on Nomex ⑧ maintains excellent electrical and mechanical properties throughout the life of the transformer. The material is not easy to age, is resistant to shrinkage and compression, and is extremely resilient, so it can ensure that the transformer remains tightly structured even after years of use, and can withstand the short circuit pressure.

Excellent moisture resistance of SG (B) 10 type H insulated dry-type power transformer

Nomex insulation system dry-type transformer is enough to resist the ingress of moisture.SG (B) 10 type H insulated dry-type power transformer adopt advanced VPI equipment and vacuum impregnation technology. High-quality dipping varnish that can run continuously for a long time at the temperature of 180 ℃ and above.

SG (B) 10 type H insulated dry-type power transformer uses DuPont Nomex paper as the main insulation material and uses it as a hybrid insulation system at the transformer hot spot, which makes the product smaller than epoxy resin cast transformer products of the same capacity. Dimensions and weight.

Environmental protection

SG (B) 10 type H insulated dry-type power transformer can be decomposed and recovered after the service life, which overcomes the defects of epoxy resin cast-type transformers which are solidified and integrated by dry resin and glass fiber, resulting in non-decomposability after the service life and pollute the environment.
