Product Description
Three-Phase Oil-Immersed Distribution Transformer
Product Parameters:
Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power components extensively utilized in electrical networks, serving primarily for voltage transformation and power transmission. Engineered to meet the demands for high current and substantial capacity, these transformers guarantee exceptional stability and reliability within the power system.
Model Meaning:
Performance Characteristics:
1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or interconnected continuous construction, enhancing the shock distribution across the winding, minimizing magnetic leakage, and providing superior mechanical strength alongside robust short-circuit resilience.
2. Iron core design:
By utilizing premium cold-rolled grain-oriented silicon steel sheets and employing a full diagonal seam stacking technique, these transformers achieve significant reductions in no-load loss and no-load current.
3. Fastening and anti-loosening:
The core and windings are meticulously secured with specialized fastening systems. High and low voltage leads feature self-locking anti-loosening nuts, with the non-hanging center structure adept at withstanding transportation-induced vibrations. All fasteners come equipped with securing nuts to preserve integrity throughout extended operation.
4. Vacuum processing:
Both coils and cores undergo a vacuum drying process, while the transformer oil is vacuum-filtered and injected to effectively limit moisture content within the transformer.
5. Oil tank design:
The oil tank is crafted from corrugated sheets with a breathing function, adapting to oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet results in a reduced transformer height.
6. Other features:
With a stunning appearance, compact size, and minimal installation footprint, these products are the epitome of maintenance-free design.
These transformers find widespread application in power plants, substations, industrial and mining enterprises, as well as rural power distribution grids. Environment and Requirements:
Ambient temperature: generally required to be between -25°C and +40°C.
Altitude limit: not exceeding 1000m.
Air humidity: not more than 90% relative humidity (at +25ºC).
Installation place: Choose an area devoid of corrosive gases and significant particulate matter.
Maintenance and upkeep:
Regular inspection: Frequent assessments of the oil level and oil insulation strength are necessary. Prompt replacement of transformer oil is required if any issues are detected.
Stable operation: To achieve stable transformer operation, it is critical to prevent overloads, short circuits, and other irregularities.
Safety attention: Before installation, consider plant ventilation and fire safety in alignment with technical specifications to ensure correct installation.
