摘　　要：为解决电能表射频辐射抗扰度试验难以通过的问题,以一款典型三相多功能电子式电能表为对象进行试验,在诊断分析并整改成功的基础上,提出了一些有针对性的解决方案。该方案要求在电能表PCB板设计初期就侧重进行优化设计,对于进一步提高电能表的设计和整改技术、拓展设计思路、增强干扰防护水平,具有重要的现实意义。In order to solving the problem that the electricity meter often failed to pass the radio frequency electromagnetic field radiated immunity test,one typical three phase multi-function electricity meter as the test object is taken.After diagnose and successful rectification,some pertinence methods are advanced.The methods suggest that the optimal design of the electricity meter PCB board should be pay more attention to.The methods are quite practical for improving the design and rectification technology of electricity meter.
