Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as pivotal power equipment extensively utilized in power systems. They excel in voltage conversion and power transmission tasks, catering to high current and large capacity demands with impressive stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a multi-layer cylindrical, continuous, or connecting continuous structure. This design enhances the winding's shock distribution, minimizes magnetic leakage, boosts mechanical strength, and offers robust short-circuit resistance.

2. Iron core design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, it significantly reduces no-load loss and no-load current, optimizing performance.

3. Fastening and anti-loosening:
Each core and winding is secured with strategic fastening measures. High and low voltage leads feature self-locking anti-loosening nuts, and a non-hanging center structure is incorporated to withstand transport vibrations. All fasteners are equipped with tightening nuts, ensuring stability during prolonged operation.

4. Vacuum processing:
Coils and cores undergo meticulous vacuum drying, while transformer oil is vacuum filtered and injected to ensure minimal moisture content, elevating the transformer's performance.

5. Oil tank design:
The oil tank features corrugated sheets with breathing functionality, accommodating oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet lowers the transformer's height.

6. Other features:
Boasting a beautiful appearance, compact size, and minimal installation footprint, these transformers are the epitome of maintenance-free excellence.
Widely applied in power plants, substations, industrial and mining enterprises, as well as rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically required to be maintained between -25°C and +40°C.
Altitude limit: should not exceed 1000 meters.
Air humidity: must remain below 90% relative humidity (at +25ºC).
Installation place: Select a location devoid of corrosive gases and significant dirt for optimal performance.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength are essential. Any issues require immediate transformer oil replacement to ensure continued reliability.
Stable operation: Guarantee the stable operation of the transformer by preventing overload, short circuits, and other anomalies.
Safety attention: Prior to installation, consider plant ventilation and fire prevention, adhering to technical specifications for proper installation.
