The testing apparatus comprises a power source generator, strain towers, a straight-line tower, conducting wires, ground wires, strain insulator strings, a suspension string and a jumper wire string, wherein one ends of the ground lines are connected with the strain towers, and the other ends of the ground lines are connected with the straight-line tower; the suspension string is arranged on the straight-line tower; one ends of the conducting wires are connected with the strain towers through the strain insulator strings, and the other ends of the conducting wires are connected with the suspension string mounted on the straight-line tower; the jumper wire strings are arranged on the strain towers; the output of the power source generator is connected with the conducting wires. According to the invention, all typical defects of an actual line can be simulated on the strain towers, the straight-line tower, the conducting wired, the suspension insulator string, the strain insulator strings and the jumper wire strings, so that the visible light and infrared inspection performance test of the multiple-rotor unmanned aerial vehicle is facilitated. The power source generator can output the alternating voltage of 110-1000 kV and direct voltages of +500 kV, -500 kV, +800 kV and -800 kV, the actual line environment at all voltage classes can be stimulated, and the transmission line inspection performance of the multiple-rotor unmanned aerial vehicle cam tested.

Description

technical field [0001] The invention belongs to the category of power transmission line operation and maintenance, in particular to a test device for performance testing of a multi-rotor UAV used for power transmission line inspection. Background technique [0002] With the development of my country's power grid industry, multi-rotor drones, as a new type of transmission line inspection method, can be used to quickly obtain transmission line body and channel information, and also have the advantages of portability and high mobility. In order to ensure the safety and applicability of multi-rotor UAVs for power transmission line inspections, it is necessary to test their flight performance and inspection performance. [0003] For the performance test of multi-rotor drones used for transmission line inspection, on the one hand, it is necessary to test its flight performance, such as load capacity, wind resistance, and endurance time. On the other hand, it is necessary to test ...
