Oil-immersed Transformers Product Details:
Oil-immersed transformers are paramount power apparatus in electrical systems, expertly engineered for efficient voltage conversion and seamless power transmission. Crafted to meet the rigorous demands for high current and extensive capacity, these transformers ensure exceptional stability and reliability across power networks.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a sophisticated multi-layer cylindrical configuration, with options for continuous or connecting continuous structures. This design enhances winding shock distribution, minimizes magnetic leakage, and ensures superior mechanical strength for robust short-circuit resistance.

2. Iron core design:
Utilizing top-grade cold rolled grain oriented silicon steel sheets, the iron core design implements a full diagonal seam stacking method, significantly reducing no-load loss and no-load current for heightened efficiency.

3. Fastening and anti-loosening:
Innovative fastening techniques secure both the core and windings, featuring self-locking anti-loosening nuts on critical components like high and low voltage leads. The non-hanging center structure withstands transportation vibrations, with all fasteners equipped with specialized nuts to prevent loosening during prolonged operation.

4. Vacuum processing:
Precision vacuum drying of coils and cores, coupled with vacuum-filtered oil filling, ensures minimal moisture presence within the transformer, enhancing its longevity and performance.

5. Oil tank design:
The oil tank integrates corrugated sheets with a breathing function, adeptly compensating for oil volume fluctuations due to temperature changes, while eliminating the need for an oil storage cabinet, thereby reducing transformer height.

6. Other features:
Elegant design with compact dimensions and minimal installation footprint, making it an ideal choice for maintenance-free operation.
Widely used in power plants, substations, industrial and mining enterprises as well as rural power grids in the power distribution system.

 

Environment and Requirements:
Ambient temperature: typically required to be between a range of -25°C to +40°C.
Altitude limit: recommended not to exceed 1000 meters.
Air humidity: should not surpass 90% relative humidity at a temperature of +25ºC.
Installation place: Select locations devoid of corrosive gases and visible contaminants for installation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks on oil levels and oil insulation strength are essential, with immediate oil replacement upon detection of issues to maintain optimal function.
Stable operation: Ensure smooth and stable transformer operation by preventing overloads, short circuits, and other irregularities.
Safety attention: Consideration of plant ventilation and fire prevention measures is crucial before installation, adhering to technical guidelines for proper setup.
