Insulator Contamination And Cleaning Robot Research

With China economic of fast development,the industry electricity volume needs constantly increased,on grid of construction and maintenance increasingly attention,and insulation child in transmission lines road in the up with mechanical connection and the electrical insulation of role,insulation child can security run is decided power system can stable run of important factors,but due to insulation child in long-term run process in the surface will attached filthy,dang encountered drizzle,and fog,weather situation Xia may will produced Flash complex,insulation child Flash complex will brings huge of economic loss and inconvenience.In order to avoid pollution flashover of insulator of insulator on-line monitoring insulator pollution flashover trend in time to the area of cleaning.Infrared thermal imaging technology is an important method for detection of insulator contamination grades and application of infrared detection technology needs to perfect the mechanism of insulator of heat,so on insulator temperature field of research is of great significance.Paper using ANSYS limited Yuan software analysis has insulation child in wet dirt uniform,wet dirt added dry with,wet dirt added dry charged arc three species State Xia of temperature distribution situation and for test research validation model of effectiveness;while using ANSYS electric coupled of method focus research has dry with on filthy insulation child temperature field distribution of effect in the including: dry with location;dry with article number;dry with week to length;dry bandwidth degrees,on insulation child radial temperature distribution of effect.Both tilt mount insulator cleaning difficulty,and at present is dominated by power manual cleaning insulator this phenomenon,presented to achieve a different installation location,insulators of different radii for a full 360-degree sweep of cleaning robot new insulator designs.Issue the final results:(1)lists the wet dirty insulators of heat balance equation;(2)insulators in different wet strength under different surface resistivity contours of temperature and temperature distribution;(3)wet strength was obtained through analysis and surface resistivity on insulator temperature distribution and drying effects of electric arc;(4)insulators in three States are obtained by analysis of temperature changes over time;(5)the dried out surface different positions now,dry zone closer to the edge of insulators,the higher the overall temperature of the insulator;(6)with the increasing width of dry insulator overall drop in temperature,and changes in temperature near the maximum temperature gradient;(7)disc dry with increase in the number of insulators under an umbrella,in addition to the overall drop in temperature,a radial temperature distribution changed little,dry with temperatures near the fittings;(8)surface of the insulator appears dry but not yet generating multi-segment ring when dry,compared with the same weeks to dry the internal temperature is low,but temperatures remain high on both ends,resulting in dry area continues,with the length of insulator temperature drying zone,but the change is unlikely until generate multi-segment when dry,temperatures dropped significantly;(9)through research to determine the model structure and size of the joints,using UG the establishment of three-dimension model of the manipulator,selects the movements required for joint of cylinder and motor;(10)based on ANSYS finite element analysis of the stress and deformation of manipulator;check the key parts of the strength and stiffness and modal analysis of the robot as a whole,determine the natural frequency and vibration mode of a manipulator,presented programmes;(11)based on ADAMS software overall motion of the manipulator kinematics and dynamics simulation analysis of obtained the movement joint displacement,velocity,acceleration and force change,eventually proved the feasibility of the design.
