| 摘 要： | 近年来,大电流的监测成了人们十分关心的问题,这是由于大电流有强磁、高压、电流大等一系列的直接监测所不能克服的问题。这就需要把高压大电流的强电信号,经过提取后变成能在实验室中直接观测的弱电信号。为此,如何从高压大电流的信号中提取出随实时信号变化而实时变化的小信号就变成了一个关键问题。详细介绍了监测信号提取的光收发电路原理和后续信号处理电路,分析了各部分的作用,给出了必要的分析结果。

| Abstract: | Recently,people are all care about the proplem of the warning of high current,because of the series problem of the problem,such as high voltage and high current.In order to solve the problem,it is necessary to convent the high current to weak signal that can be warned directly in the laboratory.So it is a core for how to transient the high current which changes following by the time into weak signal.In this paper,the circuit of optical transition and receiver and the process circuit of the follower sign is introduced.The function of them is analyzed.The necessary results of the analysis is given. |
