摘要
研究电火花线切割机床脉冲电源工作时的放电间隙特性,对极间放电状态检测、伺服系统进给控制等具有重要意义。在对节能脉冲电源整体结构进行分析的基础上,对其工作时的放电间隙伏安特性进行了研究。通过实验研究了火花放电状态出现的"阶梯"电压现象,并分析了脉宽、开路电压、切割厚度对间隙峰值电流的影响规律。
It is of great significance to study the discharge gap characteristics of energy-saving pulse generator for the purpose to detect discharge status,CNC servo control and other aspects. On the basis of analyze the whole structure, the voltage-current characteristic of energy-saving pulse generator is studied. Ladder phenomenon of gap spark voltage is explained through experiments, and influences of pulse width,open circuit voltage and workpiece thickness on gap peak current is studied.
