SCB18-(30 - 2500)/10 Three - Phase Dry - Type Distribution Transformer
The SCB18-(30 - 2500)/10 three - phase dry - type distribution transformer is a power equipment that combines advanced technology and excellent performance. It is carefully designed to meet the diverse needs of modern power distribution systems. With its leading - level design, manufacturing, and performance, it is committed to providing safe, efficient, and reliable power conversion and distribution solutions for various users.
I. Product Overview
-Model Explanation: "SCB18" represents that this transformer is a three - phase epoxy - resin cast dry - type transformer, and "18" indicates its energy - saving level, demonstrating outstanding energy - saving characteristics. "(30 - 2500)" means the capacity range is from 30kVA to 2500kVA, which can meet the power demands of different scales. It is suitable for both small - scale commercial places and large - scale industrial enterprises. "/10" indicates that the rated voltage of the high - voltage side is 10kV, which can effectively connect with common medium - voltage power grids.
-Structural Design: The core is made of high - quality cold - rolled oriented silicon steel sheets. Through the full - inclined joint and multi - level step - by - step lamination process, the no - load loss and noise level of the core are greatly reduced, and the magnetic - conducting performance of the magnetic circuit is improved. The windings are wound with copper wires and then formed by epoxy - resin vacuum casting to form a solid insulation structure. It not only has good electrical performance but also can effectively resist short - circuit impacts, ensuring the stable operation of the transformer under complex working conditions.
II. Performance Characteristics
-High - efficiency and Energy - saving: Based on advanced design concepts and the use of high - quality materials, the no - load loss and load loss of the SCB18 series transformers are significantly reduced compared with traditional products. It meets national energy - saving standards, helps to reduce users' long - term power consumption costs, and at the same time reduces energy waste, contributing to sustainable development.
-Safe and Reliable: The structural characteristics of the dry - type transformer eliminate the need for oil, avoiding the fire and environmental pollution risks caused by oil leakage. The epoxy - resin cast windings have good moisture - proof, dust - proof, and corrosion - proof properties, and can work normally in harsh environments, improving the reliability and stability of power supply.
-Low Noise: The optimized core structure and manufacturing process effectively reduce the noise during the operation of the transformer, making it especially suitable for environments where low - noise requirements are strict, such as hospitals, schools, and residential areas.
III. Technical Parameters
-Rated Capacity: Ranging from 30kVA to 2500kVA, providing flexible choices for different power consumption scenarios.
-Rated Voltage: High - voltage side: 10kV; low - voltage side can be customized according to user requirements, usually 0.4kV for general distribution applications.
-Voltage Regulation Range: Usually ±5% or other specified ranges according to user needs, which can adjust the output voltage to adapt to voltage fluctuations in the power grid.
-Insulation Class: Class F or H insulation systems are available, with excellent heat - resistance performance, ensuring the long - term stable operation of the transformer under high - temperature conditions.
-Impedance Voltage: The impedance voltage value is designed according to relevant standards and user requirements, which is crucial for limiting short - circuit current and ensuring the safe operation of the power system.
IV. Application Scenarios
-Commercial Buildings: Such as shopping malls, office buildings, and hotels, where reliable power supply and low - noise operation are required. The SCB18 series transformers can meet the large - scale power demands of these commercial facilities while ensuring a quiet environment for business operations.
-Industrial Parks: For various industrial production lines, the transformers can provide stable power support for industrial equipment. Their high - efficiency and overload - capacity features can adapt to the complex and changeable power consumption characteristics of industrial production.
-Residential Areas: To meet the power needs of residents, the low - noise and safe operation characteristics of the dry - type transformers ensure a comfortable and secure living environment.
-Public Facilities: In hospitals, schools, and other public facilities, the reliable power supply and high - safety performance of the SCB18 series transformers are of utmost importance. They can ensure the normal operation of medical equipment, teaching facilities, and other key equipment.
