    中频炉电力污染在那些方面？ 中频炉的中频频电源整流是6脉冲全波整流，存在5次、7次谐波电流超标，造成电网电能质量严重下降，电能损耗显著上升。 In what aspects is the electricity pollution of the induction melting furnace? The intermediate frequency power supply rectification of the induction melting furnace is a 6-pulse full-wave rectification, and the 5th and 7th harmonic currents exceed the standard, which causes a serious decline in the power quality of the power grid and a significant increase in power loss.
