空气等离子切焊电源的调流方式

Current adjustment of air plasma cutting welding power source

设计了空气等离子切焊机电源的调流方式;详细论述了集成芯片触发电路的连接调试等方面。由于三相电源换相点等原因,晶闸管在等离子切焊设备中很难得到可靠地应用;论述了集成芯片触发电路在切焊设备中的应用是可行的,并且效果良好。

This article designs the way of adjusting the current of air plasma cutting ＆ welding power source,deseribes the connection of triggering circuit to the integrated chip,For the changed points of three-phase power,it is difficult for SCR＇s briliant applied for cutting and welding equipment of plasma.Thls article proves that the integrated chip trigger circuit could be used in cutting and welding equipment and has good effects as well.
