SCB10 series dry-type transformer

SCB10 series dry-type transformer

**I. Interpretation of model meaning**

1. **"SCB" part**

- "S" stands for three-phase. This indicates that this transformer is a transformer used in a three-phase power system and can convert three-phase alternating current electric energy simultaneously.

- "C" represents resin-cast type. This is a common insulation method for dry-type transformers. By casting the windings with resin, the insulation performance of the windings can be improved, and the structure of the windings can be fixed, enhancing the mechanical stability of the transformer.

- "B" indicates foil winding. Foil windings have certain advantages in electrical performance. For example, they can reduce the eddy current loss of windings, improve the efficiency of the transformer, and also have good performance in heat dissipation and other aspects.

2. **"10"**

- This is the design serial number. Different design serial numbers represent differences in the structure, performance, materials, etc. of the transformer. Generally speaking, the higher the serial number, it may indicate that it is more technologically advanced. For example, the SCB10 series may have improvements in some performance indicators such as energy saving and reliability compared to previous series.

**II. Performance characteristics** 1

. **Good energy saving performance**

- The SCB10 series dry-type transformer adopts advanced design concepts and materials. Its iron core may use high-quality silicon steel sheets. This kind of silicon steel sheet has low iron loss and can effectively reduce the energy loss of the transformer during operation. At the same time, designs such as foil windings also help reduce winding losses, thereby improving the overall efficiency of the transformer and meeting the energy-saving requirements of modern power systems.

2. **Reliable insulation performance**

- Due to the adoption of resin-cast insulation, the windings are tightly wrapped by resin. This insulation method can effectively prevent the influence of external environmental factors (such as moisture, dust, etc.) on the windings and avoid electrical faults such as short circuits in the windings. Moreover, the resin has good heat resistance, enabling the transformer to operate normally within a certain temperature range and improving the safety and stability of transformer operation.

3. **Low-noise operation**

- In the design and manufacturing process, noise control is fully considered. For example, by optimizing the structure of the iron core and selecting appropriate materials, the hysteresis and eddy current noise during transformer operation can be reduced. At the same time, reasonable winding design and assembly process also help reduce the noise generated by mechanical vibration, making it suitable for places with relatively strict noise requirements, such as power distribution rooms near residential areas, hospitals, schools, etc.

4. **Limited overload capacity**

- Compared with oil-immersed transformers, the cooling method (natural air cooling or forced air cooling) of dry-type transformers determines that its overload capacity is relatively weak. When the SCB10 series dry-type transformer operates under overload, due to the limitation of heat dissipation capacity, the winding temperature will rise rapidly. Excessive temperature will accelerate the aging of insulation materials and affect the service life of the transformer. Therefore, long-term overload operation should be avoided as much as possible during operation.

**III. Application scenarios**

1. **Commercial buildings**

- In commercial places such as large shopping malls and hotels, there are higher requirements for the reliability and safety of power supply. The oil-free characteristic of the SCB10 series dry-type transformer greatly reduces the fire risk and meets the fire safety requirements of commercial buildings. At the same time, its characteristic of low-noise operation will not interfere with the commercial environment and can provide stable power supply for lighting systems, air conditioning systems, elevators and other equipment in shopping malls.

2. **Public facilities**

- For public facilities such as hospitals, schools, and libraries, safety and environmental friendliness are important factors in choosing transformers. The reliable insulation performance of this series of transformers guarantees the stability of power supply and will not pose a threat to people and equipment in public facilities due to electrical faults. Moreover, low-noise operation will not affect the medical environment of hospitals, the teaching environment of schools, and the reading environment of libraries.

3. **Industrial plants (specific types)**

- In some industrial plants with high requirements for environmental cleanliness, such as electronics factories and pharmaceutical factories, the SCB10 series dry-type transformer is an ideal choice. Its oil-free structure avoids environmental pollution that may be caused by oil leakage and can provide stable power for production equipment, lighting equipment, etc. in the plant to ensure the normal progress of the production process.
