Oil-immersed Transformers Product Details:
Oil-immersed transformers are indispensable power equipment, widely integrated into power systems for seamless voltage conversion and power transmission. This innovative design caters to the demand for high current and substantial capacity transformers in power systems, offering unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding is intricately designed with a multi-layer cylindrical, continuous, or connecting continuous structure, significantly enhancing shock distribution of the winding, minimizing magnetic leakage, and maximizing both mechanical strength and short-circuit resistance.

2. Iron core design:
Engineered with premium cold-rolled grain-oriented silicon steel sheets using a full diagonal seam stacking method, this design remarkably reduces no-load loss and no-load current, ensuring optimal efficiency.

3. Fastening and anti-loosening:
Both the core and windings are securely fastened with advanced measures. Fastening components, such as the high and low voltage leads, are equipped with self-locking anti-loosening nuts, utilizing a non-hanging center structure to withstand transportation vibrations. Every fastener is complemented with securing nuts to prevent loosening during prolonged operation.

4. Vacuum processing:
Utilizing cutting-edge vacuum processing, coils and cores are meticulously vacuum dried. Transformer oil undergoes vacuum filtration and is injected to significantly minimize internal moisture.

5. Oil tank design:
The innovative oil tank features corrugated sheets with a breathing function to accommodate oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's height efficiently.

6. Other features:
With its elegant design, compact size, and minimal installation space requirement, this product is the epitome of maintenance-free excellence, ideal for diverse applications.
This transformer finds extensive use across power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to range from -25°C to +40°C, ensuring versatile adaptability.
Altitude limit: Should not exceed 1000 meters, maintaining optimal performance.
Air humidity: Should be maintained at no more than 90% relative humidity at +25ºC, ensuring operational integrity.
Installation place: Select an area devoid of corrosive gases and evident dirt to ensure longevity and efficiency.

 

Maintenance and upkeep:
Regular inspection: Frequent monitoring of the oil level and conducting oil insulation strength tests are essential. If issues arise, prompt replacement of transformer oil is crucial.
Stable operation: Ensuring the transformer's stable operation is vital by preventing overloads, short circuits, or other anomalies.
Safety attention: Pre-installation considerations should include plant ventilation and fire prevention strategies, adhering strictly to technical specifications for correct installation.
