Design and electric field analysis of four-split spacer live working robot

In order to solve the maintenance of the four-split spacer, a robot is designed in this paper, which includes a robot walking system, a work head for removing the spacer gripper pin, a work head for the spacer gripper pin replacement, and a multi-free working platform. According to the typical defects of the spacer, the robot's function is designed and the maintenance process is proposed. Combined with the on-line method, the electric field distribution on the robot in the process of entering equipotential is obtained by simulation and analysis. According to the characteristics of electromagnetic environment, the protection design strategy of the robot is proposed, which provides support for the development of the four-split spacer live working robot.
