SCBH15 Series amorphous alloy dry transformer has low no-load loss, no oil, flame retardant since extinguishing, moisture resistance and maintenance free advantages.Now all places of ordinary dry transformer are suitable for amorphous alloy trans former (including airport, station,city subway, high-rise buildings and power plants, etc.), especially in the flammable explosive and power shortage is more suitable. The specific characteristics are:
1.Low consumption and energy saving: using isotropic soft magnetic conductive materials, small magnetization power,high resistivity, low eddy current loss. The core no-load loss and no-load current made of non-quality alloy materials are very low, only 1 / 3 of the silicon steel sheet. The no-load loss of the transformer is reduced by 75% compared with the specified value of GB /T10228. Can greatly reduce the operation cost, the energy-saving effect is remarkable.
2.Strong corrosion resistance:the amorphous alloy core is fully packaged through resin and high-temperature resistant silicone gel,effectively prevent corrosion and amorphous alloy debris off, so as to effectively protect the core and coil.
3.Low noise:in order to reduce the operating noise of the product, reasonable working maqnetic density is selected in the product design, the core and coil structure are improved in the product processing, and special noise reduction materials are adopted, etc.The product noise is far lower than the requirements of the national standard J8/T10088.
4.Strong short circuit resistance:the product adopts three-phase three-column structure around the core with compact and reasonable structure.
5.Low temperature rise, long service life: the product low temperature rise, strong heat dissipation capacity, under forced air cooling conditions can be1 50% rated load operation, the performance of the temperature control protection system can be optional, to provide reliable guarantee for the safe operation of the transformer.
About Amorphous Alloy:
Amorphous alloy is an advanced old acute cooling technology, iron, cobalt, boron, silicon and other liquid melt injection into a high speed chassis and sharp cooling, forming 0.02mm-0.04mm thin band,which has excellent soft viscosity performance, corrosion resistance, wear resistance and high resistance and other characteristics. The amorphous alloy core and cold rolled grain tend to silicon steel sheet have the following advantages:
1. Amorphous alloy material has no crystal structure, and it is an isotropic soft magnetic material with low magnetization power.
2.There is no structural defects that hinder the movement of the magnetic domain wall and the hysteresis loss is smaller than that of the silicon steel sheet.
3.The resistivity is very high, which is 3-6 times that of silicon steel sheet. its eddy current loss is greatly reduced, and the unit eddy current loss is only20%~30% of that of silicon steel sheet.
1. The altitude is not 1000m(when more than 1000m).
2. Ambient temperature: maximum temperature + 40C, hottest monthly average temperature +30°C; lowest temperature-25°C,hottest annual average temperature + 20°C
3. waveform of power supply voltage is similar to sine wave, three-phase power supply voltage isroughly symmetrical
4. Installed in the household, the use ofthe environment without obvious pollution.
