交流手弧焊机电子延时空载节能器

AC arc welder electronic delay no-load energy saver

针对交流焊机空载电流大、耗能高的弊端,设计出一种体积小、工作可靠的电子延时节能控制器。它的特点是利用电流互感器作为检测传感器,通过电子延时控制电路,使焊机空载时初级电源延时后断电,焊接时立即通电。不仅节能,而且也避免了由于短暂停焊造成电源频繁的通断,既方便又减少了对其他仪器设备的污染。

For the AC welder has the drawbacks of high no - load current and high energy consumption,this paper design a small and reliable electronic delay energy - saving controller. It’s feature is using the current transformers as detection sensor. Through the electronic delay control circuit,make the primary power source delay off when the welder no - load,and energized immediately when welding. Not only save energy,but also avoid the power frequently pass and break caused by the short pause welding. Both convenience and reduce the pollution for the other equipment.
