摘　　要：在电火花加工中 ,间隙放电状态是伺服控制的依据 ,因此间隙放电状态的检测非常重要。检测方法有很多 ,最常用的是间隙平均电压检测法和峰值电压检测法。本文提出了间隙平均脉宽电压检测法 ,其构思巧妙 ,具有方法简单、检测准确、适用范围宽等优点。Spark states of the gap are the base of servo control in EDM, so it is very important to test them. There are many methods of testing spark states of the gap, the method of testing the average or the peak value of voltage is used commonly. This paper puts forward the testing method of the average voltage in a pulse width in the gap, the thinking is handiness. This method has following advanced abilities: convenience in using, high accuracy and wide adaptability in testing and so on.
