摘　　要：基于某核电厂堆外核测量系统设备信号线缆电快速瞬变脉冲群抗扰度(EFT)试验不通过的情况,对电快速瞬变脉冲群抗扰度试验以及干扰机理进行研究。结果表明,对信号线缆增加一定屏蔽效能的屏蔽网并对屏蔽网接地能有效抑制干扰信号。为堆外核测量系统以及同类产品EFT试验提供指导,同时为后续项B电缆选型提供参考。Based on the failure of the electrical fast transient/burst immunity(EFT)test for the Extra-reactor nuclear measurement system^signal cable,the analysis of the EFT has been carries out.The result shows that measures by adding shielding on the signal cable and grounding are effective for suppress interference signal.It provides reference for the similar products9 EFT test and cable selection.
