Whether in industrial, commercial, or residential applications, this transformer stands out for its reliability and efficiency.
1.2 Model Information
The model of this transformer likely adheres to industry - standard naming conventions. For example, if it belongs to a well - known series such as the SCB series, "SCB" indicates a three - phase epoxy - resin cast dry - type construction. The model number may further detail aspects like its energy - saving class, with higher values signifying greater energy - efficiency. The 80 kVA rating clearly defines its power - handling capacity, making it suitable for a range of load requirements.
2. Structural Design
2.1 Core Structure
The core of the 80 kVA transformer is constructed 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 effectively reduces the no - load loss of the core. By minimizing no - load loss, the transformer operates more efficiently, especially during periods of low or no load. Additionally, this design helps in reducing the noise generated by the transformer, making it suitable for installations near noise - sensitive areas like residential neighborhoods, hospitals, and schools.
2.2 Winding Design
The windings are made of high - conductivity copper wires (or aluminum wires, depending on the design). After being wound, they are encapsulated in a solid insulation structure through epoxy - resin vacuum casting. The epoxy - resin provides excellent electrical insulation, ensuring that the windings can withstand high electrical stresses. This casting process also imparts mechanical strength and protection against environmental factors such as moisture, dust, and corrosion. As a result, the windings can effectively resist short - circuit impacts, which are common in power systems, ensuring the stable operation of the transformer even under challenging working conditions.
3. Performance Characteristics
3.1 High Efficiency and Energy - Saving
Our 80 kVA transformer is designed with advanced techniques and high - quality materials, resulting in outstanding energy - saving capabilities. Compared to traditional transformers, it has significantly lower no - load and load losses. This high efficiency not only helps end - users reduce their long - term power consumption costs but also contributes to a more sustainable power distribution system. By minimizing energy waste, the transformer plays a vital role in promoting environmental conservation. It meets 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 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 reliably in a wide range of environmental conditions, from humid coastal areas to dusty industrial sites. The reliable performance of the transformer 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 reduce the noise generated during the transformer's operation. In areas where the transformer is installed near residential or commercial buildings, low - noise operation is highly desirable. 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 save costs during installation and operation.
4. Technical Parameters
4.1 Rated Capacity
The rated capacity of this transformer is 80 kVA, which is suitable for a variety of electrical loads. It can provide a stable power supply to medium - sized industrial machinery, a set of commercial equipment, or a group of residential buildings. This capacity allows it to handle the power demands of a range of 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 various voltage levels depending on the power grid requirements. Common high - voltage ratings include [list some common high - voltage values like 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 80 kVA 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 80 kVA 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
