Oil-Immersed Transformers:
Oil-immersed transformers, a cornerstone of modern power systems, excel in voltage conversion and power transmission. Crafted to meet demands for high current and large capacity, they offer unparalleled stability and reliability, making them indispensable in today's power systems.
Model's Significance:
Performance Characteristics:
1. Superior Winding Structure:
The high-voltage winding features a multi-layer cylindrical design, utilizing continuous or connecting continuous structures. This innovation enhances shock distribution, minimizes magnetic leakage, bolsters mechanical strength, and ensures robust short-circuit resistance.
2. Advanced Iron Core Design:
By adopting premium cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking approach, we significantly reduce both no-load loss and no-load current.
3. Reliable Fastening and Anti-Loosening Mechanisms:
Each core and winding is meticulously secured with advanced fastening measures. Equipped with self-locking anti-loosening nuts, they adopt a non-hanging center structure, proficiently withstanding transportation vibrations. Fasteners come with nuts that ensure steadfastness even during extended operation.
4. Precision Vacuum Processing:
Through vacuum drying of coils and cores, and vacuum filtration and injection of transformer oil, we ensure minimal moisture presence inside the transformer, enhancing efficiency and longevity.
5. Innovative Oil Tank Design:
Our oil tank features corrugated sheets with a breathing function, adeptly compensating for oil volume changes due to temperature variations. The absence of an oil storage cabinet reduces the transformer's overall height.
6. Additional Remarkable Features:
Elegant design, compact size, and minimal installation footprint make it the quintessential maintenance-free solution.
Our transformers find extensive application in power plants, substations, industrial and mining enterprises, and rural power grids, seamlessly serving the power distribution system.
Conditions and Requirements:
Optimal Ambient Temperature Range: Generally maintained between -25°C and +40°C for efficient operation.
Altitude Constraints: Should not exceed 1000 meters above sea level.
Air Humidity Standards: Relative humidity should not surpass 90% at +25ºC.
Installation Site Recommendations: Select a location devoid of corrosive gases and significant dirt for optimal performance.
Maintenance and Upkeep:
Periodic Inspections: Regularly monitor oil levels and conduct oil insulation strength tests. Promptly replace transformer oil if any issues arise.
Ensuring Stable Operation: Prioritize stable transformer operation by averting overload, short circuits, and other anomalies.
Crucial Safety Precautions: Consider plant ventilation and fire prevention measures before installation, adhering to technical specifications for precise setup.
