How much do you know about silicon steel sheet of high frequency transformer?

Is the greater the silicon content in the silicon steel sheet of the transformer core, the better?

It is not found that the silicon content of silicon steel sheet has little effect on the quality of transformer, but the oriented and non oriented are related to the type of iron core. Secondly, even for the same type of iron core, if you don't handle it well, the quality difference is very big, sometimes as high as 40% or 50%.

Good core and the same data, the heat treatment and wire winding process is very important, good heat treatment only needs a very small 10mA exciting current can reach 15000 Gauss, and bad heat treatment may need 50mA Excitation current can reach the corresponding 15000 Gauss, the difference between the two is very big, from a professional point of view to judge whether the iron core is good or not, mainly through the excitation current, iron loss, saturation parameters several indicators to comprehensive.

If the splicing process is adopted for the silicon steel strip of high frequency transformer, does it mean that the quality is definitely not good?

It can't be generalized, but it's not easy to splice too many broken ends, because one more broken point means one more magnetic flux leakage point, so it's better not to exceed 2 – 3 joint points. In the production, all the broken ends and splices should be pickled first, but strictly speaking, the silicon steel sheet without splicing is the best for the ring type transformer manufacturing high-grade audio equipment, and its process quality will be more guaranteed.
