Product Description
800 kVA Three - Phase Dry - Type Distribution Transformer Product Description
1. Product Overview
1.1 General Introduction
Our 800KVA three - phase dry - type distribution transformer is a state - of - the - art electrical solution, meticulously engineered to address the complex power conversion and distribution requirements in a wide range of applications. Whether it's in large - scale industrial complexes, bustling commercial areas, or densely populated residential neighborhoods, this transformer serves as a reliable and efficient power hub.
1.2 Model Significance
The model of our 800KVA transformer follows industry - standard naming conventions. For example, if it's part of the well - known SCB series, "SCB" indicates a three - phase epoxy - resin cast dry - type construction. The model number also details aspects like its energy - saving grade. A higher energy - saving grade means greater energy efficiency, which is essential for cost - effective and environmentally friendly power consumption. The 800KVA rating precisely defines its power - handling capacity, making it suitable for medium - to - large - scale power - intensive operations.
2. Structural Design
2.1 Core Construction
The core of the 800KVA transformer is crafted from top - quality cold - rolled oriented silicon steel sheets. These sheets are assembled using a full - inclined joint and multi - level step - by - step lamination technique. This construction method effectively reduces the core's no - load loss, enhancing the transformer's efficiency, especially during low - load or no - load periods. Additionally, it significantly decreases the noise generated by the transformer, making it suitable for installation in noise - sensitive locations such as hospitals, schools, and residential areas.
2.2 Winding Design
The windings are made from high - conductivity copper wires (or aluminum wires as per the design). After winding, they are encapsulated in a solid insulation structure through epoxy - resin vacuum casting. The epoxy - resin provides excellent electrical insulation, enabling the windings to withstand high electrical stresses. This casting process also gives the windings substantial mechanical strength and protection against environmental factors like moisture, dust, and corrosion. As a result, the windings can effectively resist short - circuit impacts, ensuring the transformer's stable operation under challenging conditions.
3. Performance Characteristics
3.1 High Efficiency and Energy - Saving
Our 800KVA 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. It meets both national and international energy - saving standards, validating its energy - efficient design.
3.2 Safety and Reliability
One of the key benefits 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 cause fire hazards and environmental pollution. The epoxy - resin cast windings have excellent moisture - proof, dust - proof, and corrosion - proof properties. These features ensure that the transformer can operate reliably in various environmental conditions, from humid coastal regions to dusty industrial areas. 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 and also eliminate the need for additional noise - reduction measures, leading to cost savings during installation and operation.
4. Technical Parameters
4.1 Rated Capacity
The rated capacity of this transformer is 800KVA, making it suitable for a wide range of electrical loads. It can power large - scale industrial machinery, a comprehensive set of commercial equipment, or a significant number of residential buildings. This capacity allows 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 has 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 800KVA 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 800KVA 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
5.1 Industrial Applications
In industrial settings, such as large - scale manufacturing plants, steel mills, and chemical factories, the 800KVA transformer is an ideal choice. These industries have high - power - consuming equipment that requires a stable power supply. The transformer's ability to handle large loads, high - efficiency operation, and resistance to harsh industrial environments make it suitable for powering machinery, motors, and other electrical equipment used in the production process.
5.2 Commercial Establishments
For large - scale commercial buildings like shopping malls, convention centers, and office complexes, our 800KVA transformer can meet their substantial power needs. These establishments require power for lighting systems, air - conditioning units, elevators, and a wide range of electrical appliances. The low - noise operation of the transformer is particularly important in commercial settings as it helps maintain a comfortable environment for customers and employees. Additionally, the transformer's energy - saving features can help commercial businesses reduce their electricity costs.
5.3 Residential Applications
In residential areas, especially in large - scale apartment complexes or gated communities, the 800KVA transformer can provide a reliable power supply to a significant number of households. It can handle the combined power demands of various electrical appliances used in homes, such as air - conditioners, refrigerators, and lighting systems.
