Core and Performance Characteristics of Transformer Silicon Steel Sheet
When it comes to the use of thinner silicon steel sheet cores, different varieties of BOD, BCD, ED, SD and their irregular or variable cross-section cores can be made using oriented silicon steel thin strips (with thicknesses of 0.10, 0.08, 0.05, 0.03mm). This thinner silicon steel sheet core is mainly used in transformers and transformers that operate in the frequency range of 400Hz~30KHz.
For a long time, thinner silicon steel sheet iron cores have been widely used in radar pulse transformers, high-frequency medical X-ray power supplies, and linear accelerator modulation power supplies. In addition, thinner silicon steel sheet iron cores are also used in dust removal and water treatment power supplies. To a large extent, they will be used in different varieties of medium and high frequency power supplies and high frequency pulse transformers.
The functional characteristics of thinner silicon steel sheet iron cores are relatively high magnetic induction intensity, large output power, and small size. The high-frequency loss of thinner silicon steel core is very low, and the operating power consumption of the core below high frequency is relatively small, and the temperature rise is also very low.
The process function of thinner silicon steel sheet iron core is relatively good, as it can maintain a flat cut without falling slag, and the no-load current is also relatively small; The iron core has good high-voltage stability function in this regard; The magnetic function of the iron core is stable and there will be no aging phenomenon; The stacking coefficient of the iron core is relatively high and the volume is also very small. And in terms of its shape specifications, it will be produced according to the SJ1761-81 standard, and customized non-standard products will be made according to customer requirements.
The thinner silicon steel core used for transformers usually selects cold-rolled silicon steel sheets with a thickness of 0.35mm. According to the required size of the thinner silicon steel core, to a large extent, it will be cut into long pieces and overlapped into a "Japanese" or "mouth" shape. The thinner the thickness of the silicon steel sheet, the narrower the spliced strips will be, and the effect will be very good.
