In-Depth Product Details of Oil-immersed Transformers:
Oil-immersed transformers are indispensable power equipment, extensively utilized in power systems for precision voltage conversion and robust power transmission. Engineered for high current and vast capacity demands, this transformer promises exceptional stability and unparalleled reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The innovative high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous structure that enhances shock distribution, minimizes magnetic leakage, and ensures high mechanical strength with formidable short-circuit resistance.

2. Iron core design:
Crafted with premium cold-rolled grain-oriented silicon steel sheets, the iron core employs a full diagonal seam stacking method to significantly reduce no-load loss and no-load current.

3. Fastening and anti-loosening:
The core and windings are secured with precision fastening techniques. Equipped with self-locking anti-loosening nuts and a non-hanging center structure, they withstand transportation vibrations. All fasteners feature locking nuts to maintain stability during prolonged operation.

4. Vacuum processing:
Utilizing advanced vacuum processing, coils and cores are meticulously dried, while transformer oil undergoes vacuum filtration and injection, effectively minimizing internal moisture.

5. Oil tank design:
The oil tank, designed with a corrugated sheet for breathability, compensates for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's overall height.

6. Other features:
Boasting a sleek appearance, compact size, and minimal installation area, this product is the epitome of maintenance-free excellence.
Perfectly suited for power plants, substations, industrial and mining enterprises, as well as rural power grids within the power distribution system.

 

Environment and Requirements:
Ambient temperature: typically required to range between -25°C and +40°C.
Altitude limit: should not exceed 1000 meters.
Air humidity: must remain under 90% relative humidity (at +25ºC).
Installation place: Choose an area devoid of corrosive gases and significant dirt to ensure optimal operation.

 

Maintenance and upkeep:
Regular inspection: It is essential to frequently monitor the oil level and conduct oil insulation strength tests, promptly replacing transformer oil if issues arise.
Stable operation: Ensuring stable transformer operation involves preventing overloads, short circuits, and other anomalies.
Safety attention: Prioritize ventilation and fire prevention during installation, adhering to technical specifications for accurate setup.
