摘要
针对氧化锌避雷器(MOA)在线监测方法易受干扰的状况,提出了基于基波法的MOA在线监测系统设计方案。在深入研究DSP技术、A/D采样技术、串行通信技术及软件编程等技术的基础上,详细阐述了系统的软硬件设计。系统实现了对MOA阻性泄漏电流的采集、计算和分析,从而实时监测其健康状况。试验表明,系统效果良好。
In accordance with the situation of the other method of Metal-Oxide Arresters（ MOA） on-line monitor,which is susceptible to interfere,the design scheme based on the first harmonic method for MOA on-line monitoring system is proposed. On the basis of in-depth research on technologies of DSP,A / D sampling,serial communication,software programming and so on,the design of hardware and software of this system is described in detail. The system implements the acquisition,calculation and analysis of the resistive leakage current for MOA,thus the health status can be monitored in real time. The experiment verifies that this system offers good effects.
