Detailed Insights on Oil-immersed Transformers:
Oil-immersed transformers are pivotal power equipment, extensively utilized in power systems for efficient voltage conversion and seamless power transmission. Engineered to cater to high-current and substantial capacity transformer demands, our transformers epitomize stability and reliability in challenging power system applications.

 

Model Meaning:

 

Performance Characteristics:

1. Winding Structure:
Employing a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure for the high-voltage winding, this design enhances shock distribution within the winding, minimizes magnetic leakage, and offers superior mechanical strength and robust short-circuit resistance.

2. Iron Core Design:
The use of premium cold-rolled grain-oriented silicon steel sheets, combined with a full diagonal seam stacking method, significantly reduces both no-load loss and no-load current, elevating energy efficiency.

3. Fastening and Anti-loosening Mechanisms:
Incorporating comprehensive fastening measures for the core and windings, with self-locking anti-loosening nuts on high and low voltage leads, this non-hanging center structure is designed to endure transportation vibrations. All fasteners are equipped with secure nuts, ensuring stability and longevity during extended operations.

4. Vacuum Processing:
Through meticulous vacuum drying of coils and cores, alongside vacuum filtering and injection of transformer oil, our process ensures minimal moisture presence, thereby prolonging the transformer's lifecycle.

5. Oil Tank Design:
Featuring a corrugated sheet oil tank with a built-in breathing function, this design compensates for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's overall height.

6. Additional Features:
Our transformers boast an elegant appearance and compact size, occupying minimal installation space, positioning them as ideal maintenance-free solutions for diverse applications.
These transformers find extensive use across power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environmental Conditions and Requirements:
Ambient Temperature: Ideally, the operational temperature should range between -25°C to +40°C.
Altitude Constraints: Installation should occur at altitudes not exceeding 1000 meters.
Air Humidity: Maintain within 90% relative humidity at a temperature of +25ºC.
Installation Environment: Select locations devoid of corrosive gases, with minimal visible pollutants for optimal performance.

 

Maintenance and Upkeep:
Routine Inspection: Conduct regular checks on the oil level and perform oil insulation strength tests. Prompt transformer oil replacement is necessary upon detection of issues.
Stable Operation: Ensuring stable transformer operation involves preventing overloads, short circuits, and other anomalies.
Safety Considerations: Assess ventilation and fire prevention measures prior to installation, adhering to technical specifications for correct setup.
