Amorphous Alloy Dry Type Transformer
SCBH15 series amorphous alloy dry-type transformer products use amorphous alloy and oxygen-free copper material, which makes the no-load loss and load loss 70% and 10% lower than that of the 10-type products. SC(B)H15 series amorphous alloy dry-type transformer products are widely used in high-rises due to their good flame retardancy, low loss, strong short-circuit capability, small volume, low noise, good lightning strike resistance and uniform temperature distribution. Construction, airports, ports, subways, etc. have strict and special requirements for fire protection and environmental protection.

1. The loss value is low. The amorphous alloy transformer is made of amorphous alloy material as the core, which greatly reduces the no-load loss and the no-load current, so that the loss value of the new series products is greatly reduced.
2. The core strength is high and the noise is small. The use of advanced core end face brushing and curing process makes the amorphous alloy core form a solid whole, which improves the strength of the core and greatly reduces the noise.
3. Good flame retardancy and high safety. The high-low voltage winding of the amorphous alloy transformer is formed by resin casting, and the epoxy resin itself has a flame-retardant self-extinguishing property, so the product has good flame retardancy, good safety, and can be supplied to the center of the load.
4. Strong mechanical strength, good elasticity and lightning resistance. The coil of the amorphous alloy transformer is cast by epoxy resin, has good mechanical strength and is elastic, so that the transformer has strong tolerance to secondary short-circuit current and short-time overload. Due to the large inter-turn capacitance, the foil-type coil has a uniform potential distribution at each point of the coil under the action of lightning shock waves. Therefore, the transformer also has good lightning-impact resistance.
5. Excellent moisture resistance and easy operation and maintenance. The coil adopts a closed structure, and the epoxy resin itself has excellent electrical properties and has high moisture resistance. Even in a wet state, it has excellent characteristics of rapid recovery of surface resistance, and it is only necessary to periodically remove surface dust during operation. Go to the core, dry and other complex work.
6. Exhaust thoroughly, partial discharge is small. Since the coil is degassed and degassed under vacuum, the epoxy is poured, so the exhaust is thorough and there is no air bubble inside; the special insulation design between the coil layers makes the mechanical strength of the resin casting layer further strengthened, so the casting layer will not Cracking, the partial discharge of the transformer is small.
7. The noise is small and there is no pollution. The coil of the amorphous alloy transformer is made of epoxy resin, which is a whole body. The compression positioning takes certain measures. The coil acts as an acoustic wall around the "iron core" of the sounding body, thus making the vibration of the transformer vibrate. Improved. Because it is a dry type transformer, it is free of liquid and gas insulation, so there is no leakage and environmental pollution.
8. Complete equipment and reliable operation. The distribution transformer itself is equipped with a temperature control protection device, which can patrol and detect the operating temperature of the low-voltage coil. It can issue an alarm signal or trip when any phase low coil overheats, protecting the transformer from damage. For transformers with air-cooling devices, it is equipped with special The thermostat controls the start and stop of the machine.
