Product Description

The principle of the product is the same as the sealed type power transformer. The basic elements of amorphous alloy are iron, nickel, cobalt, silicon, boron carbon, etc. It is a soft magnetic material and its magnetizing power is low. The amorphous alloy iron is extremely thin with 0.027mm. Lamination coefficient is low with 0.75-0.8. The electrical resistivity is very high and is 3 to 6 times the silicon steel plates. The hardness is 5 times that of silicon steel sheets. No-load loss of SH15-M-30~2500/6~10 series products decreased by 70% on the basis of GB/T6541 standard value.

1. The transformer core is made of amorphous alloy strips.
2. Low-voltage windings adopts copper foil coils and a cylindrical structure. High-voltage windings use a multi-layer cylindrical structure to balance the ampere-turn distribution of the windings and minimize magnetic leakage. 
3. The transformer connection type adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the power supply quality.
4. The oil tank is corrugated structure, the cover and the edge of the box are completely welded or fastened with bolts in two types, which fundamentally prolongs the service life of the transformer oil and insulating materials.
5. All fasteners with special anti-loosening treatment.
6. The transformer adopts vacuum oil injection, which can completely eliminate bubbles in the coil and ensure stable insulation performance.

The transformer can convert the voltage of the grid into the voltage required by the system or the load, and realize the transmission and distribution of electric energy. The transformer can replace the silicon steel sheet iron core transformer and is widely used in outdoor power distribution system. A large number of this product into the network operation can achieve good energy saving effect and can reduce the pollution to the atmosphere. This product is especially suitable for power shortage and load fluctuations and areas difficult to carry out daily maintenance. The transformer adopts a fully sealed structure, protecting the insulating oil and the insulating medium from being polluted by the atmosphere, so it can operate in a humid environment. It is the ideal distribution equipment in the vast distribution network for urban and rural areas.

Why Do Transformers Fail?

An electrical transformer can blow for a variety of reasons and can cause an explosion or fire. Causes of transformer explosions could include:

· Lightning strikes

· Overheating

· Wear and corrosion

· Damage to the electrical system anywhere along the line

· Failed safety devices and power surges

· Foreign objects or animals getting into the transformer

· Moisture

When a transformer fails, it will usually result in a loud boom, a power outage, and a fireball that creates a large plume of smoke.

The final assembly begins with the removal of the core and coil assembly from the vapor phase. All internal components are re pressed under the pressure specified by the project, and now the excess water has been removed to ensure the tightness. The metal and fiber nuts are tightened or tightened as required, and the electrical clearance is verified again.

 

The core and coil assembly are placed in the tank, which is filled with oil to prevent exposure to air, and a cover assembly is added to connect with the sleeve. Once the enclosure is welded and leak checked, the galvanized radiator is assembled to the tank, the unit is drained, and the transformer is vacuum filled for final testing. During this period, the control box and any other customer specified monitors and components are installed and connected. All external welded components shall be installed to ensure correct installation to the tank and removed prior to the completion of the factory acceptance test of the transformer.
