Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment extensively employed in power systems for efficient voltage conversion and robust power transmission. Expertly designed to meet high current and large capacity demands, these transformers offer unparalleled stability and reliability, making them a cornerstone in modern power systems.

 

Understanding Model Meaning:

 

Key Performance Characteristics:

1. Advanced Winding Structure:
Our high-voltage winding utilizes a multi-layer cylindrical, continuous, or connecting continuous structure. This design significantly enhances shock distribution, minimizes magnetic leakage, and provides exceptional mechanical strength, ensuring strong short-circuit resistance.

2. Innovative Iron Core Design:
Crafted with high-quality cold-rolled grain-oriented silicon steel sheets, using a full diagonal seam stacking method to significantly reduce no-load loss and no-load current, optimizing efficiency.

3. Reliable Fastening and Anti-loosening Features:
Each core and winding is securely fastened, featuring self-locking anti-loosening nuts for critical high and low voltage leads. The non-hanging center structure withstands transportation vibrations, while fastening nuts ensure long-term operational stability.

4. Precision Vacuum Processing:
Utilizing meticulous vacuum drying for coils and cores, along with vacuum-filtered and injected transformer oil, this process effectively minimizes internal moisture, enhancing performance.

5. State-of-the-Art Oil Tank Design:
Featuring a corrugated sheet oil tank with a breathing function, it adeptly compensates for oil volume changes due to temperature fluctuations while eliminating the need for an oil storage cabinet, thus reducing transformer height.

6. Additional Features:
With an elegant appearance, compact volume, and minimal installation footprint, these transformers are the epitome of ideal maintenance-free solutions.
These transformers serve a critical role in power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environmental Considerations and Requirements:
Optimal Ambient Temperature Conditions: Typically required to be between -25°C and +40°C for optimal performance.
Maximum Altitude Limit: Installation should not exceed an altitude of 1000m.
Air Humidity Specifications: Must not exceed 90% relative humidity at a temperature of +25ºC.
Recommended Installation Location: Choose installation areas free from corrosive gases and significant dirt accumulation to ensure longevity.

 

Maintenance and Upkeep Guidelines:
Regular Inspection Protocol: Conduct frequent checks on oil level and perform oil insulation strength tests. Immediate replacement of transformer oil is necessary upon problem detection.
Ensuring Stable Operation: To ensure smooth and stable transformer operation, preventing overload, short circuits, and other potential abnormalities is crucial.
Safety Precautions and Attention: Consider necessary ventilation and fire prevention measures prior to installation, adhering to technical specifications for correct setup.
