The S11-M series fully sealed oil-immersed power transformer
The S11-M series fully sealed oil-immersed power transformer developed and produced by our company has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully-sealed transformer eliminates the oil storage tank, the oil volume change is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank, the transformer is isolated from the air, prevents and slows down the deterioration of the oil and insulation aging, enhances the operation reliability, and the normal operation is maintenance-free,
1. The transformer core is made of imported high-quality cold- rolled silicon steel sheet, which greatly reduces no-load loss and no-load current, and binds the core to ensure the firmness of the core and reduce noise. 2.The high and low voltage windings are wound with oxygen free copper, the low voltage windings are 500 kVA and below using double-layer cylinder three-sex rated capacity electric structure, 630kVA and above using double helix or quadruhelix structure, and the high voltage windings are polyphase can be laminated cylinder structure. 3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the quality of power supply. The transformer is fully sealed structure, extending the service life, no lifting center, no maintenance. 5. The measured noise value is lower than the standard. After the normal transportation of this series of transformers, without the need for lifting core inspection, you can install the relevant parts, acceptance project test, can be put into operation after passing
