Abstract
Aiming at the problem that the high-voltage inspection robot is susceptible to wind load when inspecting the
line, which leads to poor stability and low safety of the airframe, a balanced method of magnetic torque based
on HVDC magnetic f ield is proposed: The dynamic balance is achieved through the ampere torque which is
generated by the current-carrying coil in the HVDC magnetic field to offset the wind load moment. According
to the actual working conditions of the inspection robot, a magnetic torque simulation model which was calculated
and simulated was established. The results show that the model could produce a magnetic torque which
met the requirements under the set parameters. Finally, an experiment was conducted on the magnetic torque
device which showed that the torque generated by the device was sufficient to meet the requirements in nonextreme
wind speed environments. In addition, the method used the magnetic torque to offset the wind load
moment, which provided an effective idea for facing more complex load situations.
