目前岭澳一期核电站主控室采用的电感灯将逐步被LED灯替代,但LED灯配置的开关电源产生的辐射骚扰可能影响其他核电设备的正常工作,并带来电磁兼容性问题。首先根据文献调研情况提出了主控室内设备设施的辐射抗扰度水平,然后从试验和现场实测两个角度对三星、湖南麓山和Spark三种品牌的LED灯和电感灯的电磁辐射骚扰特性进行分析。结果表明:从辐射骚扰水平大小来看,考虑最严重条件下,主控室分别更换为三种LED灯后,产生的电场辐射骚扰水平和低频磁场辐射骚扰水平均远小于前述提出的核电设备辐射抗扰度水平,因此三种LED灯具均可替换目前主控室照明的电感灯。
At present, the inductive lights used in the main control room of Ling’ao Phase I nuclear power station will be gradually replaced by LED lights. However, the radiation harassment generated by the switching power supplies configured by LED lights may affect the normal operation of other nuclear power equipment and cause electromagnetic compatibility issues. First of all, based on the literature research, the radiation immunity level of the main control room equipment and facilities was put forward. Then, the electromagnetic radiation harassment characteristics of the LED and inductive lights of Samsung, Hunan Foothills and Spark were tested from two aspects of the experiment and field measurement analysis. The results show that the levels of radiated disturbance and low-frequency magnetic field radiated by the main control room are much smaller than those of the nuclear power plant radiation Immunity level, so the three LED lamps can replace the current control room lighting lamp.
