Oil-immersed Transformers Product Details:
Oil-immersed transformers are an essential component in modern power systems, designed to cater to the rigorous demands of voltage conversion and power transmission. Engineered for high current and substantial capacity, these transformers offer unparalleled stability and reliability, making them indispensable in power systems worldwide.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a multi-layer cylindrical, continuous, or connecting continuous structure, significantly enhancing shock distribution, reducing magnetic leakage, and providing superior mechanical strength and exceptional short-circuit resistance.

2. Iron core design:
Utilizing premium cold rolled grain-oriented silicon steel sheets, the innovative full diagonal seam stacking technique effectively minimizes no-load loss and no-load current, optimizing performance.

3. Fastening and anti-loosening:
Each core and winding is securely fastened with advanced measures. High and low voltage leads are equipped with self-locking anti-loosening nuts and a non-hanging center structure to withstand transportation vibrations. All fasteners are fitted with locking nuts to ensure steadfast operation over the long term.

4. Vacuum processing:
Coils and cores undergo vacuum drying, and the transformer oil is meticulously vacuum-filtered and injected, effectively minimizing moisture infiltration within the transformer.

5. Oil tank design:
The oil tank is engineered with corrugated sheets incorporating a breathing function, seamlessly accommodating oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Exuding a beautiful appearance and compact size, these transformers occupy minimal installation space and represent the pinnacle of maintenance-free solutions.
Widely utilized in power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems, these transformers ensure efficient power delivery.

 

Environment and Requirements:
Ambient temperature: Generally required to be maintained between -25°C and +40°C to ensure optimal operation.
Altitude limit: Should not exceed 1000m to maintain performance integrity.
Air humidity: Should be maintained at not more than 90% relative humidity (at +25ºC) to prevent any adverse effects.
Installation place: Select a location free from corrosive gases and obvious dirt to preserve the transformer's longevity and effectiveness.

 

Maintenance and upkeep:
Regular inspection: Frequent checks on oil levels and oil insulation strength tests are necessary. Prompt replacement of transformer oil is crucial if any issues are detected.
Stable operation: Ensure the transformer's stable operation by preventing overload, short circuits, and other irregularities.
Safety attention: Prior to installation, assess plant ventilation and fire prevention measures, ensuring alignment with technical specifications for correct installation.
