摘要
阐述了智能化低压电器产品EMC测试项目中的雷击浪涌抗扰度试验和传导发射试验所存在的共性问题。通过大量实验归纳分析了其基本的解决措施有压敏吸收、放电管释放能量、线路布局改变、加滤波电路等,并给出了整改后的效果。
The paper mainly expounds the common problems in intelligent low-voltage electrical products' EMC test of surge immunity test and conducted emission test. Its basic solutions are analyzed with pressure-sensitive absorption, discharge tube release energy, line layout changes, adding filter circuit and so on through a lot of experiments, and practical measures are given.
