ANSYS-based Finite Element Analysis of Thermal-Structural Coupling of Power Tension Clamp Monitoring Device
Tension clamps are one of the important types of components in overhead transmission lines,and their damage increases the cost of power system's safe operation,thus requiring a large number of monitoring devices.In this study a monitoring device was designed for monitoring the operation status of tension clamps.Finite element analysis of thermal-structural coupling of the device under environmental loads was conducted by using ANSYS,and stress and deformation of each part of the monitoring device under different installation contact conditions were recorded.The results show that the surface contact installation method is superior to point contact and line contact.Then by selecting the surface contact in-stallation method,the assembly with the NY400 type tension wire clamp 3D model was performed for transient thermal finite element analysis at the contact position of the drainage plate at 180℃,and the response of the monitoring device to temperature changes was obtained.
