摘要
从Maxwell时变电磁场的微分方程出发,导出了通过脉冲电流的直导线周围电磁分量的计算公式及分布情况。在生物电介质介电模型的基础上,探讨了脉冲电磁场与细胞或生物体之间的相互作用,提出了高压强流环境的电磁防护问题,初步提出脉冲高压强流环境下的安全距离。
From the eletromagnetic field equations of Maxwell,the electric and magnetic fields and their components distribution produced by a pulse current following through a finite long lead have been derived.On the basis of the bilogical dielectric model,the biological effect of electromagnetic fields have been studied and provided the question of electromagnetic protection,the primary safe areas have been estimated under highvoltage pulse current discharging environment.This work will be useful for the establishment of the standards and measures of electromagnetic protection.
