According to the problems of low efficiency and high risk of manual tower climbing in traditional transmission line voltage detection operations

it proposes a contact-based voltage detection solution based on multi-rotor unmanned aerial vehicles.Firstly

by analyzing the current bottlenecks in voltage detection operations

it designs a suspended voltage detection device for unmanned aerial vehicles(UAVs).Secondly

it optimizes and determines core parameters such as the UAV model

the length of the insulating rope

the structure of the voltage detector

and the signal transmission mode.Finally

through structural design

prototype production and on-site testing verification

the operation time of this device for voltage level lines of 500 kV and above are shortened from over 30 minutes to 10 minutes

and the accuracy rate of the voltage detection resultsreach 100%

providing a safe and efficient new technical means for the voltage detection operation of transmission lines.
