摘要: 在对自动消弧装置控制器的改进过程中 ,重新设计了基于AD1 6 74的数据采集系统 ,以克服原系统小信号测量不准、数据输出不稳、易受干扰影响的缺陷。经实验和现场挂网运行结果表明 ,改进后的数据采集系统能够很好地满足自动消弧装置宽范围输入信号的要求 ,测量准确 ,运行稳定Abstract: When improving the controller of automatic arc-suppressing device, the author redesigned data collection system based on AD1674 converter in order to remove defect that the old system cannot measure accurately and get steady output data and suppress interference very well. Improved data collection system can meet requirement of wide range input signal of automatic arc-suppressing device and its experimental operation and field showed that it has higher accuracy of measurement and better behavior than the old data collection system.
