改绕后初级2.2的纱包圆铜线线绕220匝,次级2*3的纱包扁铜线绕了180匝,使用4只100A金属封装二极管桥式整流输出,测得整流前180V整流后230V;
引弧的用电视高压包输出经8000PF15KV电容放电,经3条长的收音机天线的磁棒将引狐电压传至负极,(即割枪端)
结果现在的问题是不能电弧一点都不稳定,一直开着高压都不能连续燃烧,断断续续的,不知道是什么原因;
后来经过测量三项变压器式40A的空载电压是190V,又加绕组,现在的空载电压也合适,但还是无法正常切割,电弧都无法维持1秒,又买了47000UF电容加在整流后,还是不行,电极一下就挂了!
见到市面上卖的变压器式的等离子电源都是三相的,是不是两项的就做不好???
但是氩焊机单三项都可以呢??
