In order to improve the safety and efficiency of live working on the distribution network,the distribution network live working robot system was designed,including the master-slave teleoperation hydraulic manipulator,the control system,the live working tool system,the insulation protection system and the insulated bucket truck,etc.Its unique structure,technical parameters and working principle were described.The master-slave position closed-loop follow-up control was adopted,the master hand and the slave hand were the same structure,and the master hand had force feedback,which improved the operation flexibility and work efficiency.Tests on live lines of 10 kV distribution network have verified the rationality and superiority of the design.
