Scope of application
The transformer can replace the transformer of silicon steel sheet iron core and is widely used in outdoor power distribution system.The large-scale operation of the product into the network can achieve good energy-saving effect and reduce the pollution to the atmosphere.This product is especially suitable for power shortage and load fluctuation in and dificult to carry out and insulation medium is not polluted by air.Therefore,it can operate in wet environment.It is the ideal distribution equipment in the vast distribution network of urban and rural areas.
Model meaning
Structural features
The transformer core is made of amorphous alloy strip,and the no-load loss is about 75%lower than that of the SCB10 transformer. At low voltage,copper foil coils are used to improve the transformer's ability to withstand short circuits.
Transformer connection group adopts Dyn11 to reduce the influence of harmonics on power grid and improve power supply quality. Vacuum oil injection can completely eliminate bubbles in the wire network to ensure stable absolute slow performance.
Conditions of use
The altitude does not exceed 1000 meters.
The ambient medium temperature is not higher than+40℃;Maximum average monthly temperature+30℃;Maximum annual average temperature +20℃;Minimum temperature:-25℃ .
For indoor use.
Transformers operating under special operating conditions are available according to user requirements.Main technical parameters
