摘　　要：应用雷电监测网资料对雷电直接击于建筑物或击于建筑物附近所产生的空间磁场强度进行估算，得出在引下线周围1--5m范围磁场强度衰减值，并估算出电子信息系统机房应加装的屏蔽网格宽度。The magnetic intensity caused by direct lightning stroke on buildings or neighbors is estimated according to data from the lightning detection network, thus obtaining the attenuation value of magnetic intensity within a range of 1 to 5m around down-conductor system and estimating the width of a shielding grid installed on an electronic information system room.

关 键 词：磁场分布 安全空间 屏蔽网格宽度 雷电流幅值 分流系数 引下线 屏蔽系数 防雷设计
