Oil-immersed Transformers Product Details:
Oil-immersed transformers are quintessential power equipment in modern power systems, primarily serving the crucial functions of voltage conversion and power transmission. Crafted with precision to meet the high current and large capacity demands, these transformers offer unparalleled stability and reliability in power systems.
Model Meaning:
Performance Characteristics:
1. Winding structure:
Our high-voltage winding embraces a multi-layer cylindrical, continuous or connecting continuous structure. This advanced design optimizes shock distribution within the winding, minimizes magnetic leakage, boosts mechanical strength, and enhances resistance to short-circuits.
2. Iron core design:
By utilizing top-grade cold rolled grain-oriented silicon steel sheets and employing a full diagonal seam stacking method, our design significantly reduces no-load loss and no-load current, ensuring efficiency and performance.
3. Fastening and anti-loosening:
The core and windings are meticulously secured with robust fastening strategies. Key components, such as high and low voltage leads, are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to endure transportation vibrations effortlessly. Ensuring durability, all fasteners are complemented with locking nuts to prevent loosening over extended operation periods.
4. Vacuum processing:
Our coils and cores undergo precise vacuum drying, while the transformer oil is meticulously vacuum filtered and injected. This process is tailored to significantly reduce moisture, safeguarding the interior of the transformer.
5. Oil tank design:
Featuring an oil tank crafted from corrugated sheets with a breathing function, the design adeptly compensates for oil volume fluctuations due to temperature changes. The absence of an oil storage cabinet reduces the transformer's height, offering a sleek, efficient profile.
6. Other features:
Characterized by its aesthetic elegance and compact design, this transformer occupies minimal installation space and embodies the essence of an ideal maintenance-free product.
Our oil-immersed transformers find widespread applications in diverse settings, including power plants, substations, and industrial and mining enterprises, as well as rural power grids, perfectly catering to power distribution systems.
Environment and Requirements:
Ambient temperature: The optimal ambient temperature range is generally between -25°C and +40°C, ensuring robust performance.
Altitude limit: Ensuring efficacy and safety, these transformers are best suited for altitudes not exceeding 1000m.
Air humidity: The air humidity should remain below 90% relative humidity at a temperature of +25ºC to maintain optimal functioning.
Installation place: Select an installation site free from corrosive gases and noticeable dirt to ensure the longevity and performance of the transformer.
Maintenance and upkeep:
Regular inspection: Frequent monitoring of the oil level and performing oil insulation strength tests are imperative. Any detected issues should be promptly addressed by replacing the transformer oil.
Stable operation: To guarantee the transformer's seamless operation, avoiding overloads and preventing short circuits and other anomalies is essential.
Safety attention: Prior to installation, it is crucial to consider ventilation, fire prevention, and other safety measures, adhering strictly to technical specifications for accurate setup.
