Product Details

SCBH15 Series Amorphous Alloy Dry-type Transformer

SCBH series amorphous alloy dry-type transformer is a dry-type transformer with low loss and high energy efficiency. Its no-load loss is more than 70% lower than that of traditional transformers using silicon steel sheets as iron cores.

It is a new generation of energy-saving, safe, green and environmentally friendly high-tech products. This product can replace ordinary dry-type transformers, and is mainly suitable for high-rise buildings, commercial

centers, infrastructure, industrial and mining enterprises, power plants, etc.

Standard:IEC60076-1, IEC60076-11.

Selection

Operating conditions

1. Ambient temperature: Maximum temperature:+40°C,Minimum temperature:-25℃ .

2. Average temperature of the hottest month:+30℃,Average temperature in the hottest year:+20℃ .

3. Altitude not exceeding 1000m.

4. The waveform of the power supply voltage is similar to a sine wave.

5. The three-phase supply voltage should be approximately symmetrical.

6. The relative humidity of the surrounding air should be lower than 93%, and there should be no water droplets on the surface of the coil. 7. Where to use: indoors or outdoors.

Features

1. Low loss, good energy-saving effect, and economical operation.

2. Flame retardant, fireproof, explosion-proof and non-polluting.

3. Good moisture resistance and strong heat dissipation.

4. High mechanical strength, small partial discharge and high reliability.

5. Short-circuit resistance, high level of lightning impact, and large overload capacity. 6. Small size,lightweight, small footprint, and convenient installation

Structure

■ Iron core:

● The iron core is made of amorphous alloy material and adopts a three-phase three column structure.

● The iron core is suspended on the reinforced insulation board on the upper part of the coil, which is completely free from external force, and fully utilizes the characteristics of low no-load loss and low no-load current of the
amorphous alloy material, and the energy saving effect is obvious.

■ High and low voltage winding:

● The high and low voltage adopt rectangular winding, and the inner and outer layers are filled and wound with glass fiber mesh and glass ribbon, which are permeated and solidified with resin,and have strong resistance to cracking and
sudden short circuit.

■ Simple and beautiful structure:

● The transformer adopts a frame type clamp structure, and the coil is compressed by elastic compression nails, resulting in a simple and beautiful overall structure

■ Advanced technology:

● Using vacuum film degassing, metering pump, static mixing and other advanced technologies,Ensure the proportioning accuracy and pouring quality of the epoxy mixture.

● The HTC winding adopts advanced "airway rod" technology,Not limited by the curvature radius of the winding, one or more axial air ducts can be set at the heating center of the winding according to design requirements to achieve the

best heat dissipation effect of the entire machine,Simultaneously, multiple supporting ribs can be generated in the air duct, effectively enhancing the mechanical strength of the winding.
