Oil-immersed Transformers Product Details:
Oil-immersed transformers are indispensable power equipment widely embraced across power systems globally. Their primary role lies in efficient voltage conversion and power transmission. Crafted meticulously for high current and substantial capacity demands within power systems, these transformers stand out for their remarkable stability and unparalleled reliability.
Model Meaning:
Performance Characteristics:
1. Winding structure:
The high-voltage winding features a meticulously crafted multi-layer cylindrical design, continuous or connecting continuous structure. This innovative approach enhances shock distribution across the winding, minimizes magnetic leakage, and ensures impressive mechanical strength, along with exceptional short-circuit resistance.
2. Iron core design:
Utilizing premium quality cold-rolled grain-oriented silicon steel sheets with a complete diagonal seam stacking method effectively reduces no-load loss and no-load current, thus optimizing performance.
3. Fastening and anti-loosening:
Both the core and windings are securely fastened using specialized measures. The fastening components, such as the high and low voltage leads, are fitted with self-locking anti-loosening nuts. The innovative non-hanging center structure endures transportation vibrations, while all fasteners incorporate fastening nuts to prevent loosening during prolonged operations.
4. Vacuum processing:
The coils and cores undergo vacuum drying, and transformer oil is meticulously vacuum filtered and injected. This advanced process significantly minimizes moisture within the transformer, ensuring optimal performance and longevity.
5. Oil tank design:
The oil tank incorporates a corrugated sheet with a breathing function, adeptly managing oil volume changes due to temperature fluctuations. Notably, the absence of an oil storage cabinet reduces the transformer's height, enhancing its adaptability.
6. Other features:
With its stunning appearance, compact volume, and minimal installation footprint, this product represents the pinnacle of maintenance-free innovation.
Widely used in power plants, substations, industrial and mining enterprises as well as rural power grids in the power distribution system.
Environment and Requirements:
Ambient temperature: typically required to range between -25°C and +40°C.
Altitude limit: should not exceed 1000m.
Air humidity: should remain below 90% relative humidity at a temperature of +25ºC.
Installation place: Select locations devoid of corrosive gases and apparent dirt for optimal installation.
Maintenance and upkeep:
Regular inspection: Requires frequent monitoring of the oil level and conducting oil insulation strength tests. If issues are identified, timely replacement of transformer oil is essential.
Stable operation: To ensure the transformer's stable operation, it is imperative to prevent overloads, short circuits, and other anomalies effectively.
Safety attention: Prior to installation, it is crucial to consider plant ventilation alongside fire prevention measures, adhering strictly to technical specifications to guarantee correct installation.
