In order to detect 160~550 kN porcelain type insulator string of 500~1 000 kV UHV trans-mission line,the self-climbing robot was designed,the resistances of every insulator were measured during climbing.Given the consideration of ennergy-saving,working routes of robot are smoothed,the crawling for-ward and backward of robot was realized by manipulator finger,insulated connecting rod,electric rotating ma-chinery,voltage detection probe and control box.Furthermore,the module parameters were designed and proved to be reasonable by Ansoft Maxwell simulation.The simulation and prototype tests prove the validity of the robot detection system.
