For example, in the SCB series, "SCB" denotes a three - phase epoxy - resin cast dry - type construction. The model number further details aspects like its energy - saving grade. A higher energy - saving grade implies enhanced energy efficiency, which is crucial for cost - effective and sustainable power consumption. The 1000KVA rating precisely defines its substantial power - handling capacity, positioning it as an optimal solution for large - scale power - intensive scenarios.
2. Structural Design
2.1 Core Construction
The core of the 1000KVA transformer is fabricated from top - notch cold - rolled oriented silicon steel sheets. These sheets are assembled using a full - inclined joint and multi - level step - by - step lamination process. This construction method effectively curtails the core's no - load loss, boosting the transformer's efficiency, especially during low - load or no - load periods. Moreover, it significantly reduces the noise generated by the transformer, making it highly suitable for installation in noise - sensitive areas such as hospitals, schools, and upscale residential complexes.
2.2 Winding Design
The windings are made from high - conductivity copper wires (alternatively, aluminum wires based on the design). After winding, they are encapsulated within a solid insulation structure via epoxy - resin vacuum casting. The epoxy - resin offers excellent electrical insulation, enabling the windings to endure high electrical stresses. This casting process also imparts significant mechanical strength and protection against environmental factors like moisture, dust, and corrosion. Consequently, the windings can effectively withstand short - circuit impacts, ensuring the transformer's stable operation even in challenging working conditions.
3. Performance Characteristics
3.1 High Efficiency and Energy - Saving
Our 1000KVA transformer is engineered with advanced techniques and high - quality materials, resulting in remarkable energy - saving capabilities. Compared to traditional transformers, it exhibits considerably lower no - load and load losses. This high efficiency not only enables end - users to significantly reduce their long - term power consumption costs but also contributes to a more sustainable power distribution system. It complies with both national and international energy - saving standards, validating its energy - efficient design.
3.2 Safety and Reliability
One of the key advantages of our dry - type transformer is its oil - free design. This design eliminates the risks associated with oil - filled transformers, such as oil leakage, which can lead to fire hazards and environmental pollution. The epoxy - resin cast windings have excellent moisture - proof, dust - proof, and corrosion - proof properties. These characteristics ensure that the transformer can operate dependably across a wide range of environmental conditions, from humid coastal regions to dusty industrial zones. The transformer's reliable performance is further enhanced by its ability to maintain stable operation under different load conditions, providing a consistent power supply to connected electrical equipment.
3.3 Low Noise Operation
The design of the core and windings is optimized to minimize the noise generated during the transformer's operation. In areas where the transformer is installed near residential or commercial buildings, low - noise operation is of utmost importance. The reduced noise levels create a more comfortable environment for people living or working nearby. It also eliminates the need for additional noise - reduction measures, which can lead to cost savings during installation and operation.
4. Technical Parameters
4.1 Rated Capacity
The rated capacity of this transformer is 1000KVA, making it suitable for a diverse range of high - power electrical loads. It can provide a stable power supply to large - scale industrial machinery, extensive commercial equipment, or a large number of residential buildings. This substantial capacity enables it to handle the power demands of various applications, making it a versatile choice for different power distribution scenarios.
4.2 Rated Voltage
The high - voltage side of the transformer can be customized to different voltage levels according to the power grid requirements. Common high - voltage ratings include 10 kV, 20 kV, 35 kV, etc. The low - voltage side can also be tailored to meet the specific needs of end - users. In most general distribution applications, the low - voltage side is often set to 0.4 kV for powering commercial and industrial equipment. However, other voltage levels can be provided upon request to meet specific system requirements.
4.3 Voltage Regulation Range
The transformer is equipped with a voltage regulation range, typically ±5% or as specified by the customer. This feature allows the transformer to adjust the output voltage to compensate for voltage fluctuations in the power grid. Voltage fluctuations can occur due to changes in load demand, grid conditions, or the operation of other electrical equipment. By regulating the output voltage, the transformer ensures that the electrical equipment connected to the low - voltage side receives a stable and consistent power supply, which is essential for the proper operation and longevity of the equipment.
4.4 Insulation Class
Our 1000KVA transformer offers insulation classes such as Class F or Class H. These insulation classes have excellent heat - resistance performance. During operation, the transformer may experience varying temperatures, especially under high - load conditions. The high - quality insulation ensures that the transformer can withstand these thermal stresses without insulation breakdown, guaranteeing long - term stable operation.
4.5 Impedance Voltage
The impedance voltage of the 1000KVA transformer is carefully designed according to relevant standards and customer requirements. The impedance voltage plays a crucial role in limiting the short - circuit current in the power system. In the event of a short - circuit, the impedance of the transformer helps to control the magnitude of the short - circuit current, preventing excessive current flow that could damage the transformer and other electrical equipment in the system. This protection mechanism ensures the safe operation of the entire power system.
5. Application Scenarios
