Product Details:
Our oil-immersed transformers are a premier class of power equipment, widely recognized for their pivotal role in modern power systems. These transformers excel in voltage conversion and power transmission, tailored to meet the high current and extensive capacity demands prevalent in today's advanced power networks, ensuring unparalleled stability and reliability.
Model Meaning:
Performance Characteristics:
1. Winding structure:
Our high-voltage winding features a sophisticated multi-layer cylindrical design, with options for continuous or connecting continuous structures. This innovation enhances shock distribution, minimizes magnetic leakage, and offers high mechanical strength with robust short-circuit resistance.
2. Iron core design:
Utilizing premium cold rolled grain-oriented silicon steel sheets and a unique full diagonal seam stacking method, our design significantly reduces no-load loss and no-load current, optimizing energy efficiency.
3. Fastening and anti-loosening:
Our transformers boast meticulously fastened cores and windings, with high and low voltage leads secured by self-locking anti-loosening nuts. The non-hanging center structure is engineered to endure transportation vibrations. Additionally, all fasteners come with locking nuts, ensuring long-term operational stability without loosening.
4. Vacuum processing:
A state-of-the-art vacuum drying process for coils and cores, paired with vacuum-filtered and injected transformer oil, ensures minimal moisture presence within the transformer.
5. Oil tank design:
The oil tank features corrugated sheets with an innovative breathing function, adept at compensating for volume fluctuations due to temperature changes, eliminating the need for an oil storage cabinet and thus reducing the transformer's overall height.
6. Other features:
With an elegant design, compact size, and minimal installation footprint, our transformers are the epitome of maintenance-free convenience, perfectly suited for modern infrastructure demands.
Our transformers find extensive application in power plants, substations, industrial and mining enterprises, as well as rural power grids, making them an invaluable asset in power distribution systems.
Environment and Requirements:
Ambient temperature: typically expected to be within the range of -25°C to +40°C.
Altitude limit: should not surpass 1000 meters.
Air humidity: should remain below 90% relative humidity at a temperature of +25ºC.
Installation place: Choose an environment free from corrosive gases and noticeable dirt accumulation.
Maintenance and upkeep:
Regular inspection: It's crucial to routinely examine the oil level and oil insulation strength. Any issues detected should prompt an immediate replacement of the transformer oil.
Stable operation: Maintaining stable transformer operations involves preventing overloads, short circuits, and other irregularities.
Safety attention: Prior to installation, ensure proper plant ventilation, fire prevention measures, and compliance with technical specifications for precise and safe installation.
