通过对不同电压等级、不同设备等电位带电作业时电场分布的计算,得出人体与周围设备的电场分布图。给出不同工况下人体周围的最大场强和最大畸变率,以及人体进入高电位过程中的人体电位分布,指出带电作业人员作出典型动作时,人体突出部位电场强度较大、易发生畸变。
通過對不同電壓等級、不同設備等電位帶電作業時電場分佈的計算,得齣人體與週圍設備的電場分佈圖。給齣不同工況下人體週圍的最大場彊和最大畸變率,以及人體進入高電位過程中的人體電位分佈,指齣帶電作業人員作齣典型動作時,人體突齣部位電場彊度較大、易髮生畸變。

The human body and surrounding equipment electric field distribution map is obtained by calculation of equipotential hot-line work for different voltage grades and different equipments .The map gives the maximum field strength and maximum distortion rate for the human body around in different conditions , and provides the human body potential distribution when entering the high potential area.The paper points out that the electric field of human body prominent parts is greater and prone to distortion when the hot-line worker takes typical action.
