摘　　要：本文充分考虑了高空电磁脉冲源区与架空电力线缆之间相对位置的随机性,利用多项式混沌方法,计算了不同地磁倾角及不同架空高度下的电力线缆高空电磁脉冲传导环境。结果表明,不同地磁倾角及不同架空高度下,电力线缆终端设备所处的高空电磁脉冲传导环境不尽相同,脉冲电流峰值的变化范围为2~6 kA,脉冲上升沿的变化范围为4~12 ns,脉冲半宽的变化范围为70~150 ns。In this paper,the randomness of relative position between the source area of high-altitude electromagnetic pulse and elevated lines is fully considered,and the conducted parameters of high-altitude electromagnetic pulse elevated lines with different geomagnetic dip angles and heights are calculated by using polynomial chaos method.The results show that the variation range of pulse current peak value varies from 2 kA to 6 kA,the pulse rising edge varies from 4 ns to 12 ns,and the pulse half width varies from 70 ns to 150 ns.
