What materials are used to make up transformer silicon steel sheets
It is an alloy of silicon and iron (especially steel)
(1) Cold rolled non oriented silicon steel strip () method: DW iron loss value (iron loss value per unit component of magnetic induction with a frequency of 50 Hz and a sinusoidal peak waveform of 1.5 T). ）100 times the thickness, 100 times the thickness. For example, dw470-50 indicates a loss of 4.7 w/kg of iron and a thickness of 0.5 mm cold-rolled undirected silicon steel. Now, a new model of 50 w470 is available.
(2) The meaning of cold-rolled oriented silicon steel strip (sheet) is: DQ iron loss value (the waveform at a frequency of 50 Hz is a sine magnetic peak of 1.7 T per unit weight). ）100 times the thickness, 100 times the thickness. Sometimes the loss of iron can add high magnetic susceptibility to G. For example, dq133-30 indicates an iron loss value of 1.33 and a cold-rolled oriented silicon steel strip (sheet) with a thickness of 0.3 millimeters. The new 30 q133 model now shows this.
(3) Hot rolled silicon steel plates are divided into low silicon steel (with a silicon content of 2.8% or less) and high silicon steel (with a silicon content>2.8%) according to their silicon content, according to the doctor. Indicating method: Doctor iron loss value (magnetization, unit component iron loss value when the magnetic induction intensity is 1.5 T with multiple sinusoidal shape changes of 50 Hz) 100 times the thickness value. If dr510-50 indicates an iron loss value of 5.1 and the thickness of hot-rolled silicon steel plate is 0.5 millimeters. The brand of household appliances and hot-rolled silicon steel sheets are made of JDR iron loss value thickness value, such as JDR540-50.
