摘要
为了实时准确的测量氧化锌避雷器的泄漏电流,设计了基于各次谐波多元补偿法的氧化锌避雷器数据采集和处理系统。对电压信号和电流信号进行独立的信号采集,将数据传送给数字信号处理器,利用软件进行后续的数据处理、分析和计算。结果表明测试系统的测量数据准确,性能稳定可靠,完成了预定的研究目标。最后提出了实际测量时出现的问题和解决的方法。
A data acquisition and processing system based on multiple compensation method of harmonics is designed for measuring the leakage current of MOA accurately and real—timely.The voltage and current signals which collected separately are transmitted to the DSP.Data acquisition,signal processing and calculating have been finished in DSP.Analysis showed that the measurement system is accurate and stable,reaches the expected target.In addition,the measurement problems is proposed and solved.
