Product Details:
Our oil-immersed transformers stand as a pinnacle of innovation in power equipment, playing a crucial role in modern power systems. Specifically engineered for efficient voltage conversion and seamless power transmission, these transformers meet the high-current, large-capacity demands with exceptional stability and reliability.
Model Meaning:
Performance Characteristics:
1. Winding structure:
The high-voltage winding employs a sophisticated multi-layer cylindrical, continuous, or connecting continuous design. This results in superior shock distribution, minimal magnetic leakage, high mechanical strength, and robust short-circuit resistance.
2. Iron core design:
Utilizing premium quality, cold-rolled, grain-oriented silicon steel sheets with an advanced full diagonal seam stacking method significantly reduces no-load loss and no-load current, enhancing overall efficiency.
3. Fastening and anti-loosening:
Meticulously designed with fastening measures, the core and windings are secured with self-locking anti-loosening nuts. The innovative non-hanging center structure withstands transport vibrations, ensuring long-term operational stability and preventing fastener loosening.
4. Vacuum processing:
Employing vacuum drying for coils and cores, combined with vacuum filtration and oil injection processes, ensures minimal moisture content within the transformer, optimizing performance and longevity.
5. Oil tank design:
The oil tank is crafted with corrugated sheets that possess breathing capabilities, accommodating oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet contributes to a reduced transformer height.
6. Other features:
With its sleek appearance, compact size, and minimal installation footprint, this product is the epitome of maintenance-free design, offering unmatched convenience and aesthetics.
Widely used in power plants, substations, industrial and mining enterprises as well as rural power grids in the power distribution system.
Environment and Requirements:
Ambient temperature: typically required to range from -25°C to +40°C, ensuring optimal functionality across various climates.
Altitude limit: should not exceed 1000 meters above sea level to maintain performance integrity.
Air humidity: should remain below 90% relative humidity at a comfortable +25°C to ensure efficient operation.
Installation place: Select an installation area free from corrosive gases and evident dirt for optimal operational conditions.
Maintenance and Upkeep:
Regular inspection: Conduct frequent checks on the oil level and perform oil insulation strength tests. Address any issues promptly by replacing the transformer oil if necessary.
Stable operation: Ensure the transformer operates stably, safeguarding against overload, short circuits, and other irregularities to maintain uninterrupted functionality.
Safety attention: Before installation, consider plant ventilation, fire prevention, and adhere to technical specifications to ensure an accurate and safe setup.
