Product Details:
Oil-immersed transformers represent a quintessential element in power systems worldwide, celebrated for their superior ability to convert voltages and facilitate seamless power transmission. Crafted to meet the rigorous demands of high current and expansive capacity within power networks, these transformers are designed with exceptional stability and assured reliability.
Model Meaning:
Performance Characteristics:
1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure, which enhances the winding's shock distribution, minimizes magnetic leakage, and delivers robust mechanical strength with superior short-circuit resistance.
2. Iron core design:
Employing top-tier cold rolled grain-oriented silicon steel sheets with an innovative full diagonal seam stacking approach, this design significantly reduces no-load losses and minimizes no-load current.
3. Fastening and anti-loosening:
Both core and windings are securely fastened with precision measures. Fastening components, such as high and low voltage lead connections, are fitted with self-locking anti-loosening nuts, while a non-suspension center structure enables resilience against transport vibrations. All fasteners include nuts to ensure steadfastness during extended operations.
4. Vacuum processing:
Coils and cores undergo meticulous vacuum drying, while transformer oil is vacuum filtered and injected, effectively minimizing moisture presence within the transformer.
5. Oil tank design:
The oil tank integrates corrugated sheets with a breathing function to accommodate oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and thus reducing transformer height.
6. Other features:
Exuding elegance with its compact design and minimal installation footprint, this transformer is the quintessential maintenance-free solution.
Extensively employed across power plants, substations, industrial sectors, mining enterprises, and rural power grids as a vital component of power distribution systems.
Environment and Requirements:
Ambient temperature: Typically requires a range between -25°C and +40°C to ensure optimal performance.
Altitude limit: Should not exceed an altitude of 1000m for effective operation.
Air humidity: Must maintain relative humidity levels below 90% at +25°C for optimal performance.
Installation place: Select an installation area devoid of corrosive gases and free from significant contaminants.
Maintenance and upkeep:
Regular inspection: Routine checks on oil levels and insulation strength are crucial; should issues arise, timely replacement of transformer oil is essential.
Stable operation: Ensure the transformer operates stably by avoiding overloads, short circuits, and other irregularities.
Safety attention: Prior to installation, consider ventilation and fire prevention in line with technical standards for accurate and safe setup.
