在电火花加工机理研究、新系统开发以及分析加工设备性能时,都希望有一套通用性强的电压、电流波形测试系统,本文就此作一介绍。一、对系统的要求和配置对系统的要求:1.有合适的电压、电流测量范围2.具有测量瞬态信号的能力3.应有存贮能力和足够的存贮容量4.具有较宽的频带和高的记录速度5.能捕捉特定事件为了捕捉预定的波形供研究,就要求仪器具有预延迟触发功能,以便能记录下事件发生前后的波形信息。例如打算研究线切割加工断丝时的波形特征,就应设计出能在断丝瞬间发生信号脉冲的装置。6.多种显示方式7.能进行波形基本参数的测量
In the study of EDM mechanism, the development of new systems and the analysis of processing equipment performance, we hope that there is a universal testing system for voltage and current waveforms. This article introduces this. First, the system requirements and configuration of the system requirements: 1. There is a suitable voltage and current measurement range 2. With the ability to measure transient signals 3. Should have storage capacity and sufficient storage capacity 4. Has a wide Of the band and high recording speed 5. Capturing specific events In order to capture a predetermined waveform for the study, it requires the instrument has a pre-delay trigger to record the waveform information before and after the event. For example, to study the characteristics of waveforms when wire cutting is broken, a device that can generate a signal pulse at the moment of wire breakage should be designed. 6. A variety of display 7. Waveform can be measured the basic parameters
