Abstract

Abstract: The insulator strings of EHV and UHV transmission lines are long, and it is more convenient and effective to detect insulators with robot. The current insulator detection robots are mainly climbing style, large in volume and complex in structure, and needs to be improved. Therefore, a split-type insulator detection robot is designed, which is suitable for detection of the suspended insulator strings. The electric field distribution around the insulator robot is simulated and analyzed. The designed robot is tested for a 220 kV insulator string. The results show that the maximum electric field strength of the split-type robot is 1 753 kV/m and no partial discharge occurs. The voltage measured by the insulator detection robot is less than the original voltage distribution value of the insulator. The actual voltage distribution of insulators can be obtained through compensation and correction. The robot is used to test the low/zero resistance insulators.
