Provide users with 500kV and below, 1000MVA and below series oil immersed power transformers. stay
While digesting the advanced technology at home and abroad, combined with the advanced technology at home and abroad and our company's experience in producing power transformers for many years, through
Through optimization and innovation, we have successfully produced a series of power transformers with low noise, low loss, low partial discharge and high short-circuit resistance,
Fully comply with and superior to national standards and International Electrotechnical Commission recommended standards.
1. Low loss and low noise
The core piece adopts the laminated form of full oblique joint, and the oil tank adopts composite shielding technology
Structural parts adopt measures such as reducing eddy current loss to solve the phenomenon of local overheating.
2. Safe and reliable operation
The electrical calculation adopts simulation software for positioning and quantitative analysis to ensure sufficient electrical strength and reliability
Low loss and effective suppression of local overheating;
The local discharge is kept below 50pc, and the temperature rise of transformer winding and oil surface are low
Above 5K of national standard, yield strength of winding conductor ≥ 180n / mm2, copper conductor, transformer
It has strong short-circuit resistance, which can ensure the long-term stable operation of the transformer.
3. Easy installation and maintenance
The transformer adopts core free structure, and all accessories are pre installed in the factory.
The transformer adopts maintenance free structure and technology, and the product maintenance is simple and convenient.
4. Fine workmanship
The coil is wound by vertical winding machine and equipped with tensioning device to ensure the axial direction of all windings
Winding force to improve the mechanical strength of winding.
The combined suit process is adopted to reduce the assembly tolerance of the body and improve the overall quality of the body
strength.
All high voltage electrodes and metal structures are rounded to avoid tip discharge
