摘要
在对一款典型性单相静止式电能表电流采样信号输入端进行增加瓷片电容、串联磁珠和电流采样信号短路等试验和分析的基础上,总结提出一些针对射频电磁场辐射抗扰度试验的解决方案,整改后的电能表通过了射频电磁场辐射抗扰度试验。
Based on adding ceramic chip capacitance,ferrite bead and short circuit sampling line to the current sampling signal input on a typical single-phase static electricity meter,some pertinence methods for radio frequency electromagnetic field radiated immunity test was summarized.After rectification,the electricity meter passed the radio frequency electromagnetic field radiated immunity test.
