To make a transformer it is necessary for us to have a certain knowledge of transformer-related information, so here I will introduce the common sense of this aspect. 1, iron core data, transformer use of iron core data mainly iron, low silicon, high silicon, in the steel sheet silicon can reduce the conductivity of the steel sheet, add resistivity, it can reduce the eddy current, make its loss reduction. We usually call the silicon-added steel sheet silicon steel sheet, transformer quality of silicon steel sheet used in the quality has a great relationship, the quality of silicon steel sheet is usually indicated by magnetic flux density B, usually the B value of black iron sheet is 6000-8000, low silicon sheet is 9000-11000, high silicon sheet is 12000-16000,2. On the requirements of the wire, is a good conductive function, insulation coating to meet the function of heat resistance, and must have a certain corrosion resistance. Usually it is best to use QZ type high strength polyester enameled wire. 3, insulation data, in winding transformer, coil structure layer barrier, between the barrier between the winding resistance, all want to use insulation data, common transformer structure data can be made of phenolic cardboard, Epoxy Board, or cardboard. INTERLAYER can be used polyester film, telephone paper, 6520 composite paper and so on as barrier, around the barrier can be used yellow wax cloth, or imine film as barrier. 4, impregnation data, after winding the transformer, but also through the final process, namely impregnation insulation paint, it can enhance the mechanical strength of the transformer, improve insulation function, extend service life, usually, cresol varnish can be used as impregnating material or 1032 insulating varnish, resin varnish.
