摘　　要：磁场及传导抗扰度试验是智能高压电器的型式试验的重要组成部分,建立符合规范的智能高压电器磁场及传导抗扰度电磁屏蔽室是实施该类试验的必要条件。针对专业规范缺失之现状,结合相关CNAS规范及电磁兼容规范,文中系统研究了该类屏蔽室的电磁环境电平需要控制的电参数,包括电源线上的插入损耗、空间电磁场的屏蔽效能;分析总结出了这些参数的幅度和频率控制要求,并给出了控制方法,可为有关方规划、设计和验收该类屏蔽室提供技术参考。The test of magnetic-field and conduct sensitivity is a main item for type tests oI intelligent Fly appliances, and the EM shielded room is the necessary condition for carrying out the test. Aiming at absence for the professional specifications, this paper discusses the EM ambient level of shielded room for magnetic-field and conduct sensitivity based on the relevant CANS and EMC＇ regulations. The contents include insert loss on power lines and screening effectiveness of space. The amplitude and frequency needed to depress are analyzing and summarizing, meanwhile, the suggestion for controlling method is also provided. It may be help to those who plan to layout, design and check such the shielded room.
