不同材料机翼下1 000 kV线路直升机带电作业侵入路径研究
|
摘要
输电线路直升机带电作业侵入路径的研究已经有所开展,但目前还没有考虑不同材料机翼对侵入路径的影响。为此,文中基于轻型复合材料以及金属材料两种不同材料所制机翼,根据1 000 kV三角形排布输电线路的实际参数,建立了直升机带电作业平台(helicopter live-line work platform,HLLWP)靠近输电线路边相导线的模型。通过控制直升机带电作业平台与导线的不同侵入距离以及不同侵入角度,利用有限元法进行静电场计算,得出了直升机及作业人员的表面电场强度。基于计算结果总结得出了不同材料机翼下直升机最优侵入路径,并通过对两种材料机翼下计算结果的分析对比,对不同材料机翼的选择提出了一定的参考意见,以期为直升机带电作业的安全开展提供一些有价值的建议。
To reveal the influences of helicopter wings of different materials on the helicopter approaching path for live-line work of transmission lines, according to the parameters of an actual 1 000 kV triangular-arranged transmission lines,a helicopter live-line work platform(HLLWP)close to the side phase conductor of the trans-mission lines is established. The helicopter wings are made of light-weight composite material and metal materi-al,respectively. By controlling the approaching distance and angle of the helicopter live-line work platform to the lines,the electrostatic field is calculated via the finite element method,and the surface electric field intensi-ties of the helicopter and the operator are obtained. Based on the calculated results,the optimal approaching paths of the helicopter under different material wings are obtained. And through the analysis and comparison of the results for the wings of two materials,some suggestions for selecting wing material are offered to provide some advices about the safety of helicopter live-line work.
