不同导线排列下500kV输电线路直升机带电作业平台侵入路径

摘要

基于直升机和几种不同导线排列500 kV输电线路的实际参数,建立了直升机带电作业平台(HLLWP)靠近输电线路的模型.通过有限元方法计算了在不同的直升机带电作业平台的侵入角度和直升机带电作业平台与导线的距离下,操作人员屏蔽服和直升机作业平台表面的电场强度,基于计算结果给出了不同导线排布下,直升机带电作业平台靠近不同相导线时的最优侵入路径.%An approaching path model of HLLWP(Helicopter Live-Line Work Platform) to 500 kV UHV AC transmission lines is established based on the actual parameters of helicopter and conductor arrangements of transmission lines.The finite element method is adopted to calculate the electric field intensities of HLLWP and worker's screening clothing for different approaching angles of HLLWP and different distances between HLLWP and conductor,based on which,the optimal approaching paths of HLLWP to different phase-conductors are given for different conductor arrangements.
