Abstract

The invention discloses a silicon steel sheet used for a transformer. The silicon steel sheet comprises, by percentage, 0.07-0.1% of C, 3-3.4% of Si, 0.2-0.3% of Mn, 0.05-0.07% of Cr, 0.02-0.03% of P, 0.1-0.2% of S, 5.8-6.0% of Al, and 0.04-0.06% of Ni. The silicon steel sheet is high in magnetic conductivity and specific resistance, good in magnetization and low in cost, internal stress is good, current consistency is good, and the components are simple.

Description

technical field [0001] The invention relates to the technical field of transformer components, in particular to a silicon steel sheet used for a transformer. Background technique [0002] Transformers use the principle of mutual inductance. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. [0003] Transformers In electrical equipment and wireless circuits, transformers are often used for...
