SCBH15 series amorphous alloy dry transformer has such advantages as low no-load loss, no oil, flame retardant, self-extinguishing, moisture-free, and maintenance-free. Now, the amorphous alloy transformers are applied to all sites(including airports, railway stations, metros, high-rise buildings, and power plants)where normal dry transformers are applied, and especially they are more appropriate for places with flammable, explosive, and power shortages. The specific features are as follows:
1. Low consumption and energy-saving: the permeability magnetic materials with isotropic soft magnetism are used, with small magnetizing power, high resistivity, and low eddy current loss. The core made of amorphous alloy has low no-load loss and no-load current, only one-third of silicon steel sheets. The no-load loss of the transformer falls 75% compared to the value provided in GB/T10228. It can significantly reduce operating costs and the energy-saving effect is significant.
2. Strong corrosion resistance: the amorphous alloy core is fully encapsulated with resin and heat-resistant silicone, thus effectively preventing rust and amorphous alloy debris shedding, to protect the core and coils effectively.
3. Low noise: to reduce the running noise, a reasonable working flux density is selected in the product design; before product processing, the core and coil structure are improved, and special noise-reducing materials are used, so that the noise of the product is well below the requirement of the national standard JB/T10088.
4. Strong ability to withstand short circuits: the products adopt three phases three limb structure, adopts a frame structure spread around the core, reasonably compact.
5. Low-temperature rise and long service life: the product has low-temperature rise and strong heat-sinking capability, and can run with 150% of the rated load under the condition of forced air cooling. A temperature control protection system with perfect performance can be selected and adapted to provide reliable protection for the safe operation of the transformer.
SCB15 series Amorphous metal transformer has the advantages of low no-load loss, oil-free, self extinguishing, moisture resistance, crack resistance and maintenance free. All places where ordinary dry transformers are now used can be replaced by amorphous dry transformers, which can be used in high-rise buildings, commercial centers, airports, Oil platform, maps, tunnels, airports, stations, industrial and mining enterprises and power plants. Especially suitable for installation and use in places with high fire protection requirements such as flammable and explosive materials.
