product description
The S11-M series fully sealed oil-immersed power transformer developed and produced by Changneng Group has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution. Compared with ordinary oil-immersed transformers, the fully sealed transformers eliminate the oil storage cabinet. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is insulated from the air to prevent and slow down the deterioration of the oil and the insulation aging. , to enhance operational reliability, maintenance-free maintenance.
Features
1. The transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current, and binds the iron core to ensure the tightness of the iron core and reduce noise.
2. The high and low voltage windings are wound with oxygen-free copper, and the low-voltage windings of 500kVA and below adopt a double-layer cylindrical structure. 630kVA and above adopt double helix or four-helical structure, and high-voltage winding adopts multi-layer cylindrical structure.
3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the power supply quality.
4, the transformer is a fully sealed structure, extending the service life, free of core, maintenance-free.
5. The measured noise value is lower than the standard.
After the normal transmission of this series of transformers, the relevant parts and components can be installed without the inspection of the core, and the acceptance project test can be carried out.
