| 摘 要： | 在特高压线路巡检技术中,直升机巡视,因其巡视角度和携带的高科技装备,具有人工巡检无法比拟的优点,尤其是在巡视塔头细节和发现红外、紫外特征缺陷方面有着巨大的优势。研究和讨论直升机在巡视1 000 kV交流特高压线路的安全距离方面的应用。通过对带电安全距离、电磁场强度及飞行控制等方面的研究,解决了直升机巡视交流特高压线路的关键技术问题,并以此为基础开发出整套的交流特高压线路巡视方法,最终在带电的特高压线路上成功进行了正式的直升机巡视作业。

| Abstract: | Because of helicopter's inspection angle and high-tech equipment on board,its inspections on ultra high voltage(UHV)power lines have unmatched advantages compared to manual work,especially in tower head detail inspections and infrared/ultraviolet radiation defect detections.Some key technical problems in inspections for UHV lines with a helicopter were studied,such as safety distances for live line works,electromagnetic field intensity and flight control.Based on the study results,a set of UHV line inspecti... |
