In-Depth Overview of Oil-immersed Transformers:
Oil-immersed transformers stand as pivotal power equipment within power systems, excelling in tasks such as voltage conversion and seamless power transmission. They are meticulously engineered to meet the high current demands and large capacity requirements with unparalleled stability and reliability.

 

Model Meaning:

 

Distinctive Performance Characteristics:

1. Ingenious Winding Structure:
The high-voltage winding features a multi-layer cylindrical design, offering options like continuous or connecting continuous structures. This strategic configuration enhances the winding's shock absorption capabilities, minimizes magnetic leakage, and ensures superior mechanical strength with robust short-circuit resistance.

2. Advanced Iron Core Design:
Utilizing top-tier cold rolled grain-oriented silicon steel sheets in a full diagonal seam stacking method significantly reduces no-load loss and minimizes no-load current, optimizing energy efficiency.

3. Secure Fastening and Anti-loosening Mechanisms:
Both the core and windings are secured with specialized fastening techniques. High and low voltage leads are fortified with self-locking anti-loosening nuts, while a non-hanging center structure ensures resilience against transportation vibrations. All fasteners are equipped with locking nuts to maintain integrity during extended operation.

4. Precision Vacuum Processing:
Coils and cores undergo meticulous vacuum drying, paired with the vacuum filtration and injection of transformer oil, effectively minimizing internal moisture and boosting operational efficacy.

5. Innovative Oil Tank Design:
The oil tank is crafted with corrugated sheets incorporating breathing functionality that compensates for oil volume fluctuations due to temperature changes. This design eliminates the need for an oil storage cabinet, thereby reducing the transformer's overall height.

6. Additional Superior Features:
Boasting an aesthetically pleasing appearance, compact volume, and minimal installation space, these transformers are the epitome of ideal, maintenance-free solutions.
Extensively deployed across power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers play a vital role in enhancing power distribution systems.

 

Environmental Considerations and Requirements:
Optimal Ambient Temperature Range: The transformers are designed to operate efficiently within a temperature range of -25°C to +40°C.
Altitude Limitation: Operational altitude should not exceed 1000 meters to maintain performance standards.
Humidity Control: The ideal operational environment features a relative humidity not exceeding 90% at a temperature of +25ºC.
Recommended Installation Location: Choose areas devoid of corrosive gases and prominent dirt to ensure optimal performance and longevity.

 

Regular Maintenance and Upkeep:
Proactive Regular Inspection: It is critical to consistently monitor the oil level and conduct oil insulation strength tests. Should any issues arise, timely replacement of the transformer oil is essential.
Ensuring Stable Operation: To maintain stable transformer operation, it is important to guard against overloads and short circuits, preventing potential anomalies.
Attention to Safety Protocols: Prior to installation, considerations regarding plant ventilation and fire prevention must be addressed, adhering strictly to technical specifications for precise installation.
