Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as pivotal power equipment in modern power systems, expertly designed to facilitate voltage conversion and power transmission. Engineered to meet the demands of high current and large capacity requirements, these transformers boast unmatched stability and reliability, ensuring seamless operations in power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a meticulously crafted multi-layer cylindrical, continuous, or connecting continuous structure. This enhances the shock distribution across the winding, minimizes magnetic leakage, and offers exceptional mechanical strength and robust short-circuit resistance.

2. Iron core design:
The use of premium cold-rolled grain oriented silicon steel sheet with an innovative full diagonal seam stacking technique dramatically reduces no-load loss and minimizes no-load current, elevating efficiency.

3. Fastening and anti-loosening:
Core and windings are securely fastened with advanced locking measures. High and low voltage leads come equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure. This design withstands transport vibrations, and all fasteners include locking nuts to prevent loosening during extended operation.

4. Vacuum processing:
Both coils and cores undergo meticulous vacuum drying, with transformer oil meticulously vacuum filtered and injected. This precision process ensures minimal moisture presence within the transformer.

5. Oil tank design:
Ingeniously designed, the oil tank features a corrugated sheet with breathing capability, adeptly compensating for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, optimizing spatial efficiency.

6. Other features:
Designed with an aesthetically pleasing appearance, compact volume, and minimal installation footprint, this is the quintessential maintenance-free solution.
These transformers find widespread application in power plants, substations, industrial and mining enterprises, and rural power grids, seamlessly integrating into power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to range from -25°C to +40°C.
Altitude limit: Must not exceed 1000m.
Air humidity: Should not surpass 90% relative humidity (at +25ºC).
Installation place: Select an area devoid of corrosive gases and conspicuous dirt for installation.

 

Maintenance and upkeep:
Regular inspection: It is imperative to frequently monitor the oil level and conduct oil insulation strength tests. Any issues should prompt immediate replacement of transformer oil.
Stable operation: Ensure the transformer's stable operation, vigilantly preventing overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, consider plant ventilation and fire prevention. Adhere to technical specifications for precise installation.
