Description
Product Brief
The S20-M-30-2500/10-NX2 series fully sealed oil-immersed power transformer developed and produced by the company has the advantages of low loss, low noise and high efficiency, and can achieve good energy saving effect and reduce pollution. Compared with ordinary oil-immersed transformers, the fully sealed oil-immersed transformer cancels the oil storage cabinet, the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated oil tank, the transformer oil is isolated from the air, preventing and slowing down the deterioration and insulation aging of the transformer oil, enhancing operational reliability, and normal operation is maintenance-free.
Model Meaning
Conditions of use
1. The installation height does not exceed 1000m above sea level (normal time), and the special environment is explained separately;
2. The ambient temperature is not higher than 40°C;
3. The minimum outdoor temperature is -25°C.
Transformers operating under special conditions of use are available upon request.
Product Features
1. The transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load and no-load current, and lashes the iron core to ensure the compactness of the iron core and reduce noise.
2. High and low voltage windings are wound with oxygen-free copper, low voltage windings 500kVA and below adopt double-layer cylindrical structure, 630kVA and above adopt double helix or four helix structure or copper foil winding, high voltage winding adopts multi-layer cylindrical structure.
3. Dyn11 is adopted in the transformer coupling group to reduce the impact of harmonics on the power grid and improve the quality of power supply.
4. The transformer is fully sealed structure, prolonging service life, no hanging core, no maintenance.
5. Low voltage standard for measured noise value.
After normal transportation, this series of transformers can be installed without core inspection, and the acceptance project test can be carried out, and it can be put into operation after qualifying.
