Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers are pivotal power devices extensively utilized within power systems, serving primarily for seamless voltage conversion and efficient power transmission. They are meticulously engineered to meet the demand for high current and substantial capacity in power systems, ensuring exceptional stability and steadfast reliability.

 

Model Meaning Explained:

 

Performance Characteristics Highlighted:

1. Advanced Winding Structure:
The high-voltage winding features a multi-layer cylindrical design, with continuous or connecting continuous structures. This significantly enhances shock distribution across the winding, minimizes magnetic leakage, bolsters mechanical strength, and provides robust short-circuit resistance.

2. Innovative Iron Core Design:
Utilizing premium cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design effectively reduces no-load loss and no-load current, promoting efficiency.

3. Secure Fastening and Anti-loosening Measures:
The core and windings are securely fastened using advanced fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to withstand transportation vibrations. All fasteners feature locking nuts to prevent loosening throughout prolonged operation.

4. Precision Vacuum Processing:
Coils and cores undergo vacuum drying, with transformer oil vacuum-filtered and injected to minimize internal moisture, optimizing performance and longevity.

5. Optimized Oil Tank Design:
The oil tank utilizes corrugated sheets with a breathing function to accommodate oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and reducing the transformer's height.

6. Additional Distinctive Features:
Showcasing a beautiful appearance, compact volume, and minimal installation footprint, these transformers are the quintessential maintenance-free solution.
Extensively deployed in power plants, substations, industrial and mining enterprises, and rural power grids, these transformers are integral to power distribution systems.

 

Environmental Conditions and Requirements:
Optimal Ambient Temperature: Typically recommended between -25°C and +40°C for optimal performance.
Altitude Limitations: Should not exceed 1000m to maintain efficiency.
Air Humidity Parameters: Should not exceed 90% relative humidity at +25ºC to ensure reliability.
Ideal Installation Location: Select a site free from corrosive gases and significant dirt for optimal performance.

 

Maintenance and Upkeep Guidelines:
Regular Inspection Protocols: Conduct frequent checks on the oil level and perform oil insulation strength tests; replace transformer oil promptly if issues are detected.
Ensuring Stable Operation: Maintain stable operation by avoiding overloads, short circuits, and other anomalies.
Safety Considerations: Prior to installation, consider adequate plant ventilation and fire prevention. Ensure compliance with technical specifications for proper installation.
