Is the stator three phase line voltage the same? And is it current zero? 定子三相电压是否相等?其电流是否为零?
Quality square wave power supply, current zero crossing time is short, arc stability, arc without high frequency stability. 优质方波电源,电流过零时间短,电弧稳定,无需高频稳弧。
But there should be no doubt that starting from the current zero tax rate on carbon, increased taxation would be desirable. 但毫无疑问的是,以当前碳排放零税率为起点而增加的税收将是可行的。
And is it current zero? 其电流是否为零?
The equipment ensures automatic closing at current zero, preset test voltage automatically and the effect is fine. 设备自动保证过电流零点(CZ)合闸,自动预置试验电压,试验效果好。
