摘要
行波波头到达时刻差的确定是保证行波测距精度的关键。本文根据行波测距的要求,采用4通道60MHz采集卡设计了专用的数据采集系统,并利用此数据采集系统进行了模拟实验。实验结果显示,所检测行波信号波头突变特性明显,在此基础上,可较容易实现对于行波波头到达时刻的精确确定。
Wave-head arriving time detection is important for traveling wave method. This design a paper data acquisition system for fault location by using 4 channel/60MHz high speed acquisition card, by which Analogue experiment is carried out . The result shows the experiment wave has good abrupt features which indicate this system has good performance.
