针对架空输电线路巡检作业需求，设计制造了具有弹簧阻尼减振结构的二轴三框架小型无人机载吊舱系统，并挂载无人机进行了超高压架空输电线路巡检试验；通过试验数据可知，小型无人机载吊舱系统稳定精度满足输电线路巡检需求，可清晰观测输电线路外观运行情况及线路周围树木生长状况，并为快速、有效地发现和消除超高压输电线路的故障提供清晰图像信息，在高纬度和低温环境下应用优势明显；巡检结果验证了小型无人机载吊舱系统理论分析的合理性和对高压输电线路巡检的实用性。%According to operation requirement for overhead transmission lines inspection, the small Unmanned Aerial Vehicle (UAV) airborne pod system structure is designed and manufactured which has two axis three framework with spring damping system, being assembled into the UAV for ultrahigh pressure overhead transmission lines inspection test. The test data showed that the accuracy of the small UAV airborne pod system stabilization met the requirement of transmission line inspection. The operation situation of transmission line and the growth situation of the trees around the transmission lines could be clearly observed. In order to quickly,effectively discover and eliminate ultrahigh pressure transmission line fault, the clear image information is provided, which had obvious superiority with the environment of high altitude and low temperature. The rationality of theoretical analysis and the practicability of transmission lines in-spection for small UAV airborne pod system were verified.
