Oil-immersed Transformers Product Details:
Oil-immersed transformers represent a pinnacle of power equipment, widely embraced in power systems for their exceptional voltage conversion and power transmission capabilities. Crafted to meet high current and large capacity demands, these transformers are engineered for unmatched stability and reliability within power systems.

 

Model Meaning:

 

Performance Characteristics:

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

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

3. Fastening and anti-loosening:
Each core and winding is meticulously secured with effective fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, paired with a non-hanging center structure. This ensures resilience against transportation vibrations. All fasteners are furnished with securing nuts, guaranteeing stability during long-term operations.

4. Vacuum processing:
With coils and cores undergoing vacuum drying, and transformer oil being vacuum filtered and injected, this meticulous process effectively minimizes internal moisture within the transformer.

5. Oil tank design:
The oil tank is innovatively designed with corrugated sheets that boast a breathing function, accommodating oil volume changes due to temperature fluctuations. This eliminates the need for an oil storage cabinet and effectively reduces the transformer's height.

6. Other features:
The transformer boasts a sleek appearance, compact volume, and minimal installation footprint, making it an ideal maintenance-free solution.
Extensively utilized in power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers are integral to power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically conditioned to range from -25°C to +40°C.
Altitude limit: Should not surpass 1000 meters.
Air humidity: Should maintain relative humidity below 90% at +25ºC.
Installation place: Select a site devoid of corrosive gases and obvious contamination.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on the oil level and perform oil insulation strength tests. Promptly replace transformer oil if issues are detected.
Stable operation: Ensure the transformer operates stably, preventing overloads and short circuits to maintain optimal function.
Safety attention: Prior to installation, address plant ventilation and fire prevention as per technical specifications to ensure correct installation.
