Oil-immersed Transformers Product Details:
Oil-immersed transformers, an essential component in modern power systems, excel in voltage conversion and power transmission. Engineered to meet the demands for high current and large capacity, these transformers offer unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous design. This innovative structure enhances winding shock distribution, minimizes magnetic leakage, and ensures superior mechanical strength along with robust short-circuit resilience.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, the iron core employs a full diagonal seam stacking method. This design significantly reduces no-load loss and minimizes no-load current, enhancing efficiency.

3. Fastening and anti-loosening:
The core and windings are secured with specialized fastening measures, complemented by self-locking anti-loosening nuts on high and low voltage leads. The non-hanging center structure effectively withstands transportation vibrations, and all fasteners come with nuts to ensure stability during extended operation.

4. Vacuum processing:
With coils and cores vacuum-dried and transformer oil undergoing vacuum filtration and injection, this meticulous process ensures minimal moisture within the transformer, optimizing performance.

5. Oil tank design:
The oil tank, designed with corrugated sheets possessing breathing capabilities, adeptly compensates for oil volume fluctuations caused by temperature changes, eliminating the need for an oil storage cabinet and effectively reducing transformer height.

6. Other features:
Boasting a beautiful appearance, compact size, and minimal installation footprint, this product stands as the perfect low-maintenance solution.
Ideal for power plants, substations, industrial and mining enterprises, as well as rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Should typically range between -25°C and +40°C.
Altitude limit: Not surpassing 1000m.
Air humidity: Must not exceed 90% relative humidity at 25ºC.
Installation place: Select locales devoid of corrosive gases and significant dirt accumulation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks on oil level and insulation strength are crucial. Should any issues arise, timely replacement of transformer oil is imperative.
Stable operation: Ensuring steady transformer operation is vital, with measures to avert overloads, short circuits, and any irregularities.
Safety attention: Prior to installation, assess ventilation and fire prevention at the plant, adhering to technical specifications for precise setup.
