一种测量工业环境感应传导干扰的方法

         

摘要

针对采用干扰测量仪或频谱分析仪只能测量工业环境中干扰源的辐射干扰强度的问题,提出了一种测量工业环境感应传导干扰的方法.该方法采用HBYV非双绞2芯线作为干扰接收体,采用数字示波器记录干扰波形的最大幅值和单个脉冲的最大强度,通过与标准干扰发生器感应到HBYV非双绞2芯线上的干扰信号大小进行比较,确定干扰强度.以瞬变脉冲群干扰强度和浪涌干扰强度的测量为例,详细介绍了该方法的具体实现.%In view of problem that interference meter or spectrum analyzer can only measure radiated interference intensity of interference source in industrial environment, the paper proposed a measuring method for induced and conducted interference in industrial environment. The method uses HBYV non-twisted-pair 2-core cable as interference acceptor and uses digital oscilloscope to record the maximum amplitude of interference waveform and the maximum intensity of the single pulse, which are compared with interference signal of HBYV non-twisted-pair 2-core cable induced by a standard interference generator to determine interference intensity. Implementation of the method was introduced in details by examples of measurement of transient pulse train interference intensity and surge interference intensity.
