Study On The Stress Of Column Procelain Insulator Of Isolating Switch And The Monitoring Device

According to statistics,in the last 30 years,the fault of porcelain insulator is frequent,and the light is caused by the damage of the isolated switch.The role of the ceramic post insulator in the junction of the palm is the role of the bus wire,will produce the stress in the porcelain insulator,and the position of the umbrella in the umbrella position to produce stress concentration,if not installed properly,will be a fracture accident.Firstly,this chapter analyzes the basic theory,including the structure and classification of porcelain insulator,the failure mechanism,the finite element method,the stress analysis and detection method,and the stress field of the crack tip.Based on the finite element method,the stress distribution of porcelain insulator.The principle of finite element software ANSY is introduced,and the related principle of linear elastic fracture mechanics is analyzed,including the stress field at the crack tip,the stress intensity factor,and the cracking principle.The load theory of the applied force is explained.The theoretical premise of elastic mechanics finite element analysis.Based on the finite element method,the principle and the simulation model of the stress are constructed,including the process analysis of the generating point,the analysis of the generating line and the analysis of the generating surface.Then,the paper studies the stress detection device of the porcelain insulator.First,the overall design,analysis of the relevant hardware device design,including the main control system,the composition of the control system hardware structure.Again,analysis of the design of software equipment,such as the system’s needs analysis,data collection,calculation,processing and display,operation software design and security measures of design and so on.
