1.2 Model Significance
The model of our 2500KVA transformer follows strict industry - standard naming conventions. For example, if it belongs to a well - known series like SCB, "SCB" indicates its three - phase epoxy - resin cast dry - type construction. The model number further provides crucial details such as its energy - saving grade. A higher energy - saving grade not only means lower power consumption but also reflects the use of advanced manufacturing techniques and top - quality materials. The 2500KVA rating clearly defines its large - scale power - handling capacity, making it an ideal choice for applications with substantial power requirements.
2. Structural Design
2.1 Core Construction
The core of the 2500KVA transformer is made from high - quality 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 is highly effective in minimizing the core's no - load loss. By reducing no - load loss, the transformer operates more efficiently, even during periods of low or no load. Additionally, this design significantly reduces the noise generated during operation, making it suitable for installation in noise - sensitive areas such as hospitals, schools, and upscale residential neighborhoods.
2.2 Winding Design
The windings of the 2500KVA transformer are crafted from high - conductivity copper wires (alternatively, aluminum wires based on design specifications). After winding, they are encapsulated within a solid insulation structure through epoxy - resin vacuum casting. The epoxy - resin provides excellent electrical insulation, allowing the windings to withstand high electrical stresses. This casting process also imparts strong mechanical strength and protection against environmental factors such as moisture, dust, and corrosion. As a result, the windings can effectively resist short - circuit impacts, ensuring the transformer's stable operation under challenging working conditions.
3. Performance Characteristics
3.1 High Efficiency and Energy - Saving
Our 2500KVA transformer is designed with state - of - the - art technologies and premium materials, resulting in outstanding energy - saving capabilities. Compared to traditional transformers of similar capacity, it has significantly lower no - load and load losses. This high efficiency not only leads to substantial long - term cost savings for end - users but also contributes to a more sustainable power distribution system. It meets or exceeds 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 cause 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 in various environmental conditions, from humid coastal areas 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 crucial. 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 2500KVA, making it suitable for handling extremely large - scale electrical loads. It can provide a stable power supply to large - scale industrial complexes with heavy - duty machinery, large - scale commercial facilities with extensive electrical systems, or large - scale residential developments with a high density of households. This capacity allows it to meet the power demands of various large - scale 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 2500KVA 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 2500KVA 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.
