耐张线夹是架空输电线路的重要组成部件之一,其损坏导致电力系统安全运行成本的增加,因此需要大量相关监测装置.设计了一款耐张线夹监测装置,用于耐张线夹运行状况的监测.利用ANSYS对装置进行环境载荷下的热-结构耦合的有限元分析,记录监测装置在不同安装接触情况下各部位的应力和变形,所得结果表明面接触安装方式优于点接触和线接触.选取面接触安装方式与NY400 型耐张线夹三维模型完成装配,进行引流板接触位置 180℃情况下的瞬态热有限元分析,获取监测装置对引流板接触位置温度变化的响应情况.
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.
