Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment, renowned for their wide application in power systems. They primarily serve the critical roles of voltage conversion and power transmission. These transformers are meticulously designed to meet the high current and large capacity demands within power systems, offering exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding is engineered with a multi-layer cylindrical, continuous, or connecting continuous structure. This design significantly enhances the winding's shock distribution, minimizes magnetic leakage, and provides high mechanical strength. It also offers robust short-circuit resistance, ensuring superior performance.

2. Iron core design:
Utilizing high-quality cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design effectively reduces no-load loss and no-load current, optimizing transformer efficiency.

3. Fastening and anti-loosening:
The core and windings are securely fastened with comprehensive fastening measures. Components like high and low voltage leads are equipped with self-locking anti-loosening nuts and a non-hanging center structure to endure transportation vibrations. All fasteners are meticulously equipped with fastening nuts to ensure they remain secure during prolonged operation.

4. Vacuum processing:
Both coils and cores undergo vacuum drying, while transformer oil is meticulously vacuum filtered and injected, minimizing moisture within the transformer to enhance longevity and performance.

5. Oil tank design:
Featuring a corrugated sheet with a breathing function, the oil tank adeptly compensates for the oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, streamlining installation.

6. Other features:
This transformer boasts a beautiful appearance and compact volume, occupying minimal installation space. It stands as an ideal maintenance-free solution, offering unparalleled convenience.
Widely and effectively used in power plants, substations, industrial sectors, mining enterprises, and rural power grids as integral components of power distribution systems.

 

Environment and Requirements:
Ambient temperature: The ambient temperature is generally required to be maintained between -25°C and +40°C, ensuring optimal performance.
Altitude limit: The installation altitude should not exceed 1000m to ensure operational efficiency.
Air humidity: Relative air humidity should remain below 90% at temperatures of +25ºC to maintain ideal conditions.
Installation place: Select an installation area free from corrosive gases and conspicuous dirt, ensuring a clean environment for optimal functionality.

 

Maintenance and upkeep:
Regular inspection: Regularly inspect the oil level and test the oil insulation strength. If issues are detected, promptly replace the transformer oil to maintain performance.
Stable operation: Guarantee the transformer's stable operation by preventing overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, consider plant ventilation and fire prevention. Adhere strictly to technical specifications for proper installation.
