交流焊接变压器装有自动控制开关,使焊机在焊接间隙自动切断电源,这是为了降低交弧焊机的空载损耗降低温升,提高电源电路的功率因数,从而提高焊接变压器的运用经济性,达到节约用电和安全用电的目的。由于这样,大家在这方面的意见越来越多。因此关于空载时焊接变压器的电流切断问题是一需待解决的问题,但如不预先在技术经济指标上进行分析比较,盲目
AC welding transformers equipped with automatic control switch, the welding machine automatically cut off power in the welding gap, which is to reduce the no-load loss of arc welding machine to reduce temperature rise and improve the power circuit power factor, thereby enhancing the utilization of welding transformer economy , To achieve the purpose of saving electricity and safe electricity. Because of this, everyone has more and more opinions in this regard. Therefore, the no-load welding transformer current cut off is a problem to be solved, but if not in advance on the technical and economic indicators for analysis and comparison, blind
