Finite element analysis and vibration control of the Substation Equipment Water Washing Robot with Hot-line
The insulator strings in substation which are long time exposed in the outdoor environment are easily accumulation industrial and natural filth. So they need to be cleaned regularly to prevent the power outages and other incidents because of flashover phenomenon which occurs in the weather of rain and fog and other inclement weather. The substation equipment water washing robot with hot-line is employed in the substation to clean the insulator strings with the same method of artificial flushing. The theory of finite element analysis and modal analysis are based in this paper. The reliability and precision of robot's structural in the process of washing operation are ensured by stress distribution and deformation from the static analysis; The low order natural frequencies and mode shapes are carried out through modal analysis and a vibration control and optimization scheme is proposed to reduce the effects of vibration in the condition of the flushing operation, and the robot's stability can be improved.
