摘要
接触器分断时会产生频率很高、幅值很大的过电压 ,采用一般的检测设备很难测出其动态波形。本文介绍一种基于DSP的高速数据采集系统 ,对接触器分断时的过电压进行采集 ,绘出过电压动态波形。
When the contactor breaks, it produces high frequency and high amplitude over voltage signals. It is very difficult to test the dynamic waveform of the over voltage signal for common test instruments. In the paper, a kind of high speed data collection system based on DSP was introduced, in which the over voltage signals produced during breaking contactor are collected and the dynamic waveforms are drawn.
