Summary
The transformer can transform the grid voltage into the voltage required by the system or load, and realize the transmission and distribution of electric energy. The transformer can replace the transformer with silicon steel core and is widely used in outdoor power distribution system. The large-scale operation of the product can achieve good energy-saving effect and reduce air pollution. This product is especially suitable for areas with insufficient power, large load fluctuation and difficulty in routine maintenance. Because the transformer adopts the fully sealed structure, the insulating oil and the insulating medium are not polluted by the air, so it can operate in the humid environment, and it is the ideal distribution equipment in the urban and rural distribution network.

Structural features
The core of transformer is made of amorphous alloy strip. The no-load loss is about 80% lower than that of S9 transformer and 25% lower than that of JB / T10318 Right; copper foil coil is used for low voltage to enhance the ability of transformer to withstand short circuit; Dyn11 is used for connection group to reduce the influence of harmonics on power grid and improve the quality of power supply; the oil tank and tank cover are welded as a fully sealed structure of one lifting body to extend the service life and avoid maintenance; vacuum oil injection is used for transformer to completely eliminate air in coil Before leaving the factory, each transformer is tested for full wave lightning impulse with peak voltage 25% higher than the national standard to ensure the safe and reliable operation of the transformer.
Amorphous alloy is a new type of energy-saving material, which is produced by rapid condensation. Its physical state is that the metal atoms are arranged in disorder amorphous. Its crystal structure is completely different from that of silicon steel, which is more favorable for magnetization and demagnetization. The thickness of its core piece is very thin, only 0.025mm, less than 1 / 10 of the common silicon steel sheet. The transformer with amorphous alloy core is a new type of energy-saving product, which has the characteristics of high saturation magnetic induction strength, low loss, low exciting current and good temperature stability. The core adopts single frame or three-phase five column coil core. Sheet or formed frame structure for core clamping. High and low voltage coils are of rectangular structure. The amorphous alloy transformer has the advantages of low no-load loss, strong short-circuit resistance, advanced structure, energy saving and environmental protection, which is in line with the industrial policy of "saving resources, protecting the environment and building a saving society" advocated by the Chinese government. It is an ideal distribution transformer for energy saving. The amorphous alloy distribution transformer introduced by our company has been widely used in factories, mines, parks, communities, stations, docks and other places. It is the most ideal replacement product of the old type of energy transformer.
